Technical Field

[0003] The present application belongs to the field of electrochromic technology, and in particular relates to a testing method, system, electronic device and storage medium for an electrochromic product. Background Art

[0004] Electrochromic technology uses an applied electric field to alter the physical or chemical properties of a medium, causing the intensity and frequency of a light beam emitted through the medium to change, thereby adjusting the transmittance or color of the light beam. In recent years, products that utilize electrochromic technology, such as liquid crystal glass and electrochromic tunable films, have been increasingly applied to various fields such as electronic devices, wearable devices, transportation, and architecture.

[0005] Different application areas require different performance characteristics of electrochromic products, and the operating environments they face also vary. When operating in different environments, to ensure stable charging and discharging to achieve dimming and avoid malfunctions, electrochromic products often require pre-operation stability testing to extend their service life. However, how to conduct operational stability testing for electrochromic products is a pressing technical issue.

[0006] Summary of the Invention

[0007] In view of this, the present application provides a testing method, system, electronic device and storage medium for an electrochromic product to solve the technical problem in the prior art that it is impossible to perform working stability testing on electrochromic products.

[0008] A first aspect of the present application provides a method for testing an electrochromic product, comprising: determining test parameters corresponding to environmental characteristics of a test scene, the test parameters including charge and discharge parameters; and performing a charge and discharge cycle test on the electrochromic product based on the charge and discharge parameters.

[0009] In the first aspect of the present application, by determining the corresponding test parameters according to the environmental characteristics of the test scenario and performing a cycle test on the electrochromic product according to the charge and discharge parameters, the working stability of the electrochromic product in the corresponding test scenario can be verified, which is beneficial for developers to match the scenario with the charge and discharge parameters, thereby improving the service life of the electrochromic product after leaving the factory.

[0010] Optionally, the environmental characteristics of the test scenario include a preset temperature or a preset temperature range, and determining the test parameters corresponding to the environmental characteristics of the test scenario includes determining the charge and discharge parameters based on a correspondence between the preset temperature or temperature range of the test scenario and the charge and discharge parameters. Thus, the charge and discharge parameters for the electrochromic product can be directly determined based on the correspondence between the preset temperature or temperature range and the charge and discharge parameters, thereby simplifying the entire testing process and improving testing efficiency.

[0011] Optionally, the environmental characteristics of the test scenario include a preset temperature or a preset temperature range, and determining the test parameters corresponding to the environmental characteristics of the test scenario includes: determining a temperature interval corresponding to the preset temperature or preset temperature range based on the preset temperature or preset temperature range of the test scenario; and determining the charge and discharge parameters based on the temperature interval and the correspondence between the temperature interval and the charge and discharge parameters. Thus, it is possible to first determine the temperature interval within which the preset temperature or preset temperature range corresponding to the scenario falls, and then select the charge and discharge parameters corresponding to the temperature interval as the test parameters. This can simplify the setting of the charge and discharge parameters, that is, the charge and discharge parameters only need to be set based on different temperature intervals, and do not need to be set separately based on multiple temperatures within the same temperature interval, thereby simplifying the operation process of the test equipment and facilitating improved stability and reliability of the test equipment.

[0012] Optionally, the environmental characteristics of the test scene include a preset temperature or a preset temperature range, and the test parameters corresponding to the environmental characteristics of the test scene include: determining the temperature interval corresponding to the preset temperature or preset temperature range based on the preset temperature or preset temperature range of the test scene; determining the transmittance change interval of the electrochromic product based on the temperature interval and the correspondence between the temperature interval and the transmittance change interval; determining the charge and discharge parameters based on the transmittance change interval and the correspondence between the transmittance change interval and the charge and discharge parameters. Taking into account the influence of temperature on the transmittance variation range of electrochromic products, by determining different transmittance variation ranges corresponding to different temperature ranges, and then determining the charge and discharge parameters based on the transmittance variation ranges, when the charge and discharge cycle test of the electrochromic product is performed using the charge and discharge parameters determined in the above manner, the transmittance variation results of the electrochromic product can be made more reliable, thereby improving the user experience; and, by separately considering the transmittance variation ranges corresponding to different temperature ranges, it can also prevent the electrochromic product from being overcharged or over-discharged at the preset temperature or within the preset temperature range of the test scenario, which can further improve the stability and reliability of the cycle test of the electrochromic product.

[0013] Optionally, the charge and discharge parameters include charge parameters and discharge parameters, wherein the charge parameters include charge voltage and / or charge current, and at least one of charge cut-off current, charge cut-off time, and charge cut-off capacity; and the discharge parameters include discharge voltage and / or discharge current, and at least one of discharge cut-off current, discharge cut-off time, and discharge cut-off capacity. Preferably, the charge parameters include charge voltage and charge cut-off capacity, and the discharge parameters include discharge voltage and discharge cut-off current. Thus, the charge and discharge parameters determined according to the environmental characteristics of the test scene can include both charging parameters and discharging parameters, which facilitates charging and discharging of the electrochromic product according to the charging parameters and discharging parameters, that is, performing a charge and discharge cycle test on the electrochromic product; and, by making the charging parameters include charging voltage and / or charging current, and making the discharging parameters include discharge voltage and / or discharge current, the electrochromic product can be charged and discharged based on voltage or current, simplifying and more effectively controlling the charge and discharge cycle process, and by selecting one of the three cut-off modes of cut-off current, cut-off time and cut-off capacity, the applicability of the test method can be improved; further, by making the charging parameters include charging voltage and charging cut-off capacity, and the discharging parameters include discharge voltage and discharge cut-off current, the charging capacity cut-off (charging charge amount) and discharge current cut-off modes can be adopted in the charging and discharging processes, respectively, so that the transmittance of the electrochromic product during the cycle test can be relatively more stable, more in line with the user's usage requirements of the electrochromic product during actual use, etc., thereby further improving the effectiveness and accuracy of the cycle test.

[0014] Optionally, the environmental characteristics of the test scenario include a preset temperature or a preset temperature range, and the test scenario includes at least one of a mild scene, a maximum temperature scene, a high temperature scene, a low temperature scene, and a sub-high temperature and high humidity scene, wherein the preset temperature or preset temperature range of the maximum temperature scene is greater than the preset temperature or preset temperature range of the high temperature scene, the preset temperature or preset temperature range of the high temperature scene is greater than the preset temperature or preset temperature range of the sub-high temperature and high humidity scene, the preset temperature or preset temperature range of the sub-high temperature and high humidity scene is greater than the preset temperature or preset temperature range of the mild scene, and the preset temperature or preset temperature range of the mild scene is greater than the preset temperature or preset temperature range of the low temperature scene. Thus, the preset temperature or preset temperature range can be set for different test scenarios according to the requirements of different test scenarios.

[0015] Optionally, the test parameters include a preset number of cycles, and the performing of a charge-discharge cycle test on the electrochromic product according to the charge-discharge parameters includes: performing a charge-discharge cycle on the electrochromic product according to the charge-discharge parameters until the number of charge-discharge cycles reaches the preset number of cycles. Thus, the corresponding preset number of cycles can be determined based on the environmental characteristics of the test scenario. By setting the preset number of cycles, the electrochromic product can be subjected to a charge-discharge cycle test in the corresponding test scenario, and the number of charge-discharge cycles can be monitored. When the number of charge-discharge cycles reaches the preset number of cycles, the charge and discharge in the scenario is stopped. This allows for more effective and comprehensive control of the charge-discharge cycles in the test scenario, preventing situations such as insufficient test times (too short a test time) or excessive test times (too long a test time).

[0016] Optionally, the environmental characteristics of the test scenario include a preset temperature or a preset temperature range, or the environmental characteristics of the test scenario include a preset temperature or a preset temperature range, and a preset humidity or a preset humidity range; and determining the test parameters corresponding to the environmental characteristics of the test scenario includes determining the preset number of cycles based on the preset temperature or the preset temperature range of the test scenario, or based on the preset temperature or the preset temperature range, and the preset humidity or the preset humidity range of the test scenario. Thus, by associating the preset number of cycles of the test scenario with the temperature condition or the humidity condition, a correlation can be established between the preset number of cycles and the environmental quality of the actual application scenario of the electrochromic product, making the test more closely aligned with the actual application scenario and fully verifying the operational reliability of the electrochromic product in the actual application scenario.

[0017] Optionally, determining the preset number of cycles based on the preset temperature or preset temperature range of the test scenario, or based on the preset temperature or preset temperature range and the preset humidity or preset humidity range of the test scenario, includes: determining the total number of cycles of the charge-discharge cycle test of the electrochromic product; determining the proportion of the number of charge-discharge cycle tests performed in the test scenario based on the preset temperature or preset temperature range of the test scenario, or based on the preset temperature or preset temperature range and the preset humidity or preset humidity range of the test scenario; and determining the preset number of cycles based on the total number of cycles and the proportion of the number of cycles. Thus, by determining the total number of cycles and determining the preset number of cycles for each test scenario based on the total number of cycles and the proportion of the number of cycles, the proportion of each test scenario can be made close to the frequency of occurrence of each application scenario, further fully verifying the working reliability of the electrochromic product in actual application scenarios.

[0018] Optionally, determining the preset number of cycles based on the preset temperature or preset temperature range of the test scenario, or based on the preset temperature or preset temperature range and the preset humidity or preset humidity range of the test scenario, includes: determining the total number of cycles based on the expected service life and the expected average daily number of color changes of the electrochromic product; determining the proportion of time spent in the test scenario in the expected service life based on the preset temperature or preset temperature range of the test scenario, or based on the preset temperature or preset temperature range and the preset humidity or preset humidity range of the test scenario; and determining the preset number of cycles based on the total number of cycles and the proportion of time spent. Thus, by associating the total number of cycles with the expected service life and the expected average daily number of color changes of the electrochromic product, the test can be made more closely aligned with actual application scenarios, further fully verifying the operating reliability of the electrochromic product in actual application scenarios.

[0019] Optionally, when the test scenario includes at least one of the highest temperature scenario, the high temperature scenario, the low temperature scenario, and the sub-high temperature and high humidity scenario, the number of times meets at least one of the following conditions: the number of times the charge and discharge cycle test is performed in the highest temperature scenario accounts for no less than 10%, the number of times the charge and discharge cycle test is performed in the high temperature scenario accounts for no less than 10%, the number of times the charge and discharge cycle test is performed in the low temperature scenario accounts for no less than 10%, and the number of times the charge and discharge cycle test is performed in the sub-high temperature and high humidity scenario accounts for no less than 10%. Thus, in the test process of the electrochromic product, by ensuring that the number of tests in various extreme environments (such as the highest temperature scenario, the high temperature scenario, the low temperature scenario, and the sub-high temperature and high humidity scenario, etc.) meets certain proportion requirements, on the one hand, the test can be made closer to the actual application scenario, and on the other hand, the test requirements for the electrochromic product can be further improved, thereby not only ensuring the working reliability of the electrochromic product in the actual application scenario, but also improving the life of the electrochromic product in actual use.

[0020] Optionally, the test scenarios include at least two of a mild scenario, a maximum temperature scenario, a high temperature scenario, a low temperature scenario, and a sub-high temperature and high humidity scenario; determining the test parameters corresponding to the environmental characteristics of the test scenarios includes: determining the test parameters corresponding to the environmental characteristics of different test scenarios respectively; and performing a charge-discharge cycle test on the electrochromic product according to the charge-discharge parameters includes: performing a charge-discharge cycle test on the electrochromic product according to the charge-discharge parameters in different test scenarios. Preferably, performing a charge-discharge cycle test on the electrochromic product according to the charge-discharge parameters includes: performing a charge-discharge cycle on the electrochromic product according to the charge-discharge parameters in different test scenarios respectively, until the number of charge-discharge cycles reaches a preset number of cycles corresponding to the different test scenarios. Therefore, according to the actual application scenario requirements of the electrochromic product, multiple appropriate test scenarios can be selected, and the same electrochromic product can be subjected to charge and discharge cycles in different test scenarios. That is, serial charge and discharge cycle tests can be performed on the electrochromic product. This can make the testing process closer to the actual application scenario, thereby better considering the actual performance of the electrochromic product in different application scenarios, which is conducive to a more comprehensive understanding of the color change performance and working stability of the electrochromic product.

[0021] Optionally, the test scenario includes at least one of a mild scene, a maximum temperature scene, a high temperature scene, a low temperature scene and a sub-high temperature and high humidity scene, and the environmental characteristics of the test scenario include a preset temperature or a preset temperature range, wherein the preset temperature or preset temperature range of the maximum temperature scene is greater than the preset temperature or preset temperature range of the high temperature scene, the preset temperature or preset temperature range of the high temperature scene is greater than the preset temperature or preset temperature range of the sub-high temperature and high humidity scene, the preset temperature or preset temperature range of the sub-high temperature and high humidity scene is greater than the preset temperature or preset temperature range of the mild scene, and the preset temperature or preset temperature range of the mild scene is greater than the preset temperature or preset temperature range of the low temperature scene; and the charge and discharge parameters include at least one of a first charge and discharge parameter, a second charge and discharge parameter, a third charge and discharge parameter and a fourth charge and discharge parameter, the preset number of cycles includes at least one of a first preset number of cycles, a second preset number of cycles, a third preset number of cycles and a fourth preset number of cycles, and the test method includes at least one of the following test steps. Less one: determine the first charge and discharge parameters and the first preset number of cycles corresponding to the environmental characteristics of the highest temperature scene or the high temperature scene, and perform a first charge and discharge cycle on the electrochromic product based on the first charge and discharge parameters until the number of the first charge and discharge cycles reaches the first preset number of cycles; determine the second charge and discharge parameters and the second preset number of cycles corresponding to the environmental characteristics of the mild scene, and perform a second charge and discharge cycle on the electrochromic product based on the second charge and discharge parameters until the number of the second charge and discharge cycles reaches the second preset number of cycles; determine the third charge and discharge parameters and the third preset number of cycles corresponding to the environmental characteristics of the low temperature scene, and perform a third charge and discharge cycle on the electrochromic product based on the third charge and discharge parameters until the number of the third charge and discharge cycles reaches the third preset number of cycles; determine the fourth charge and discharge parameters and the fourth preset number of cycles corresponding to the environmental characteristics of the secondary high temperature and high humidity scene, and perform a fourth charge and discharge cycle on the electrochromic product based on the fourth charge and discharge parameters until the number of the fourth charge and discharge cycles reaches the fourth preset number of cycles.

[0022] In this case, the electrochromic product can be tested individually in only one test scenario, or it can be tested serially in multiple test scenarios, depending on the requirements of the actual application scenario of the electrochromic product, so that the testing process is closer to the actual application scenario.

[0023] Preferably, the testing method includes: first, determining first charge-discharge parameters and a first preset number of cycles corresponding to the environmental characteristics of the highest temperature scene or the high temperature scene, and performing a first charge-discharge cycle on the electrochromic product based on the first charge-discharge parameters until the number of the first charge-discharge cycle reaches the first preset number of cycles; and / or, determining third charge-discharge parameters and a third preset number of cycles corresponding to the environmental characteristics of the low temperature scene, and performing a third charge-discharge cycle on the electrochromic product based on the third charge-discharge parameters until the number of the third charge-discharge cycle reaches the third preset number of cycles; and / or, determining fourth charge-discharge parameters and a fourth preset number of cycles corresponding to the environmental characteristics of the medium temperature and high humidity scene, and performing a fourth charge-discharge cycle on the electrochromic product based on the fourth charge-discharge parameters until the number of the fourth charge-discharge cycle reaches the fourth preset number of cycles. Then, determining second charge-discharge parameters and a second preset number of cycles corresponding to the environmental characteristics of the mild scene, and performing a second charge-discharge cycle on the electrochromic product based on the second charge-discharge parameters until the number of the second charge-discharge cycle reaches the second preset number of cycles. In this case, since electrochromic products are greatly affected by the environment (especially harsh environment), during the testing process of electrochromic products, by first subjecting them to charge and discharge cycles in extreme scenarios (such as at least one of the highest temperature scenario, high temperature scenario, low temperature scenario and sub-high temperature and high humidity scenario), and then subjecting them to charge and discharge cycles in a mild scenario, if the electrochromic product itself has certain defects, they can be identified more quickly in the early testing process, thus eliminating the need for subsequent charge and discharge cycles in a mild scenario, thereby saving testing time.

[0024] Preferably, the testing method includes: first, determining second charge-discharge parameters and a second preset number of cycles corresponding to the environmental characteristics of a mild scene, and performing a second charge-discharge cycle on the electrochromic product based on the second charge-discharge parameters until the number of the second charge-discharge cycles reaches the second preset number of cycles. Then, determining first charge-discharge parameters and a first preset number of cycles corresponding to the environmental characteristics of a maximum temperature scene or a high temperature scene, and performing a first charge-discharge cycle on the electrochromic product based on the first charge-discharge parameters until the number of the first charge-discharge cycles reaches the first preset number of cycles; and / or, determining third charge-discharge parameters and a third preset number of cycles corresponding to the environmental characteristics of a low temperature scene, and performing a third charge-discharge cycle on the electrochromic product based on the third charge-discharge parameters until the number of the third charge-discharge cycles reaches the third preset number of cycles; and / or, determining fourth charge-discharge parameters and a fourth preset number of cycles corresponding to the environmental characteristics of a medium high temperature and high humidity scene, and performing a fourth charge-discharge cycle on the electrochromic product based on the fourth charge-discharge parameters until the number of the fourth charge-discharge cycles reaches the fourth preset number of cycles. As a result, the entire testing process can be made closer to the actual application scenarios of electrochromic products, improving the validity and reliability of the test results.

[0025] Optionally, the test method further includes: placing the electrochromic product in a storage scenario for a preset time; wherein the storage scenario includes at least one of a mild scenario, a maximum temperature scenario, a high temperature scenario, a low temperature scenario, and a sub-high temperature and high humidity scenario, wherein the preset temperature or preset temperature range of the maximum temperature scenario is greater than the preset temperature or preset temperature range of the high temperature scenario, the preset temperature or preset temperature range of the high temperature scene is greater than the preset temperature or preset temperature range of the sub-high temperature and high humidity scene, the preset temperature or preset temperature range of the sub-high temperature and high humidity scene is greater than the preset temperature or preset temperature range of the mild scenario, and the preset temperature or preset temperature range of the mild scene is greater than the preset temperature or preset temperature range of the low temperature scene. Thus, by placing the electrochromic product in a storage scenario, the static stability of the electrochromic product in the corresponding storage scenario can be tested to obtain the static performance and static stability of the electrochromic product.

[0026] Optionally, at least one of the maximum temperature scene, the high temperature scene, the sub-high temperature and high humidity scene, the mild scene, and the low temperature scene satisfies the following conditions: the preset temperature or preset temperature range of the maximum temperature scene is within a range greater than or equal to 70°C, the preset temperature or preset temperature range of the high temperature scene is between 55°C and 70°C, the preset temperature or preset temperature range of the sub-high temperature and high humidity scene is between 35°C and 55°C, the preset humidity or preset humidity range of the sub-high temperature and high humidity scene is between 70%RH and 100%RH, the preset temperature or preset temperature range of the mild scene is between 10°C and 35°C, and the preset temperature or preset temperature range of the low temperature scene is within a range less than or equal to 10°C. Thus, the temperature or humidity corresponding to each test scene can be adaptively adjusted according to the needs of the actual application scenario, so that the test of the electrochromic product is more in line with the actual application scenario, and the applicability and reliability of the test method can be further improved.

[0027] The second aspect of the present application provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the steps of the electrochromic product testing method provided in the first aspect of the embodiment of the present application are implemented.

[0028] The third aspect of the present application provides a testing system for electrochromic products, the testing system comprising a main control device and a tester, the main control device and the tester being connected; wherein the main control device is used to determine test parameters corresponding to the environmental characteristics of the test scenario, the test parameters including charge and discharge parameters; and the tester is used to perform a charge and discharge cycle test on the electrochromic product based on the charge and discharge parameters. In the second aspect of the present application, the main control device determines the corresponding test parameters based on the environmental characteristics of the test scenario, and the tester performs a cycle test on the electrochromic product based on the charge and discharge parameters. Through the cooperation of the main control device and the tester, a charge and discharge cycle test of the electrochromic product in the test scenario can be implemented. Thus, the working stability of the electrochromic product in the corresponding test scenario can be verified, which is beneficial for developers to match the scenario with the charge and discharge parameters, thereby improving the service life of the electrochromic product after leaving the factory.

[0029] Optionally, the environmental characteristics of the test scenario include a preset temperature or a preset temperature range, and the master control device is specifically configured to determine the charge and discharge parameters based on a correspondence between the preset temperature or temperature range of the test scenario and the charge and discharge parameters.

Thus, the main control device can first determine the temperature interval within which the preset temperature or preset temperature range corresponding to the scenario falls, and then select the charge and discharge parameters corresponding to the temperature interval as the test parameters. This can simplify the setting of the charge and discharge parameters, that is, the charge and discharge parameters only need to be set based on different temperature intervals, and do not need to be set separately based on multiple temperatures within the same temperature interval, thereby simplifying the operation process of the test device and facilitating improving the stability and reliability of the test device.

[0031] Optionally, the environmental characteristics of the test scene include a preset temperature or a preset temperature range, and the main control device is specifically used to: determine the temperature interval corresponding to the preset temperature or preset temperature range according to the preset temperature or preset temperature range of the test scene; determine the transmittance change interval of the electrochromic product based on the temperature interval and the correspondence between the temperature interval and the transmittance change interval; determine the charge and discharge parameters according to the transmittance change interval and the correspondence between the transmittance change interval and the charge and discharge parameters. Taking into account the impact of temperature on the transmittance variation range of electrochromic products, the main control device determines different transmittance variation ranges corresponding to different temperature ranges, and then determines the charge and discharge parameters based on the transmittance variation ranges. Therefore, when the charge and discharge cycle test of the electrochromic product is performed using the charge and discharge parameters determined in the above manner, the transmittance variation results of the electrochromic product can be made more reliable, thereby improving the user experience; and, by separately considering the transmittance variation ranges corresponding to different temperature ranges, it can also prevent the electrochromic product from being overcharged or over-discharged within the preset temperature or within the preset temperature range of the test scenario, which can further improve the stability and reliability of the cycle test of the electrochromic product.

[0032] Optionally, the charge and discharge parameters include charge parameters and discharge parameters, wherein the charge parameters include charge voltage and / or charge current, and at least one of charge cut-off current, charge cut-off time, and charge cut-off capacity; and the discharge parameters include discharge voltage and / or discharge current, and at least one of discharge cut-off current, discharge cut-off time, and discharge cut-off capacity. Preferably, the charge parameters include charge voltage and charge cut-off current, and the discharge parameters include discharge voltage and discharge cut-off current. More preferably, the charge parameters include charge voltage and charge cut-off capacity, and the discharge parameters include discharge voltage and discharge cut-off current.

[0033] Thus, the charge and discharge parameters determined by the main control device according to the environmental characteristics of the test scene can include both charging parameters and discharging parameters, so that the tester can charge and discharge the electrochromic product according to the charging parameters and discharging parameters respectively, that is, perform a charge and discharge cycle test on the electrochromic product; and, by making the charging parameters include the charging voltage and / or charging current, and making the discharging parameters include the discharge voltage and / or discharge current, the tester can charge and discharge the electrochromic product based on the voltage or current, simplifying and more effectively controlling the charge and discharge cycle process, and by selecting one of the three cut-off modes of cut-off current, cut-off time and cut-off capacity, the applicability of the test method can be improved; further By making the charging parameters include the charging voltage and the charging cut-off current, and the discharging parameters include the discharge voltage and the discharge cut-off current, the process of charging and discharging tests on electrochromic products can be simplified and the test efficiency can be improved; further, by making the charging parameters include the charging voltage and the charging cut-off capacity, and the discharging parameters include the discharge voltage and the discharge cut-off current, the tester can adopt the charging capacity cut-off (charging charge amount) and the discharge current cut-off methods during the charging and discharging processes respectively, which can make the transmittance of the electrochromic product during the cycle test relatively more stable, more in line with the user's usage needs during the actual use of the electrochromic product, etc., thereby further improving the effectiveness and accuracy of the cycle test.

[0034] Optionally, the environmental characteristics of the test scenario include a preset temperature or a preset temperature range, and the test scenario includes at least one of a mild scene, a maximum temperature scene, a high temperature scene, a low temperature scene, and a sub-high temperature and high humidity scene, wherein the preset temperature or preset temperature range of the maximum temperature scene is greater than the preset temperature or preset temperature range of the high temperature scene, the preset temperature or preset temperature range of the high temperature scene is greater than the preset temperature or preset temperature range of the sub-high temperature and high humidity scene, the preset temperature or preset temperature range of the sub-high temperature and high humidity scene is greater than the preset temperature or preset temperature range of the mild scene, and the preset temperature or preset temperature range of the mild scene is greater than the preset temperature or preset temperature range of the low temperature scene. Thus, the main control device can set the preset temperature or preset temperature range for different test scenarios according to the requirements of different test scenarios.

[0035] Optionally, the test parameters include a preset number of cycles, and the tester is specifically configured to: perform charge and discharge cycles on the electrochromic product according to the charge and discharge parameters until the number of charge and discharge cycles reaches the preset number of cycles. Thus, the main control device can determine the corresponding preset number of cycles based on the environmental characteristics of the test scenario. By setting the preset number of cycles, the electrochromic product can be subjected to a charge and discharge cycle test in the corresponding test scenario, and the number of charge and discharge cycles can be monitored. When the number of charge and discharge cycles reaches the preset number of cycles, the tester is controlled to stop charging and discharging in the scenario. This allows for more effective and comprehensive control of the charge and discharge cycles in the test scenario, preventing situations such as insufficient test times (too short a time) or excessive test times (too long a time).

[0036] Optionally, the environmental characteristics of the test scenario include a preset temperature or a preset temperature range, or the environmental characteristics of the test scenario include a preset temperature or a preset temperature range, and a preset humidity or a preset humidity range; and the main control device is specifically configured to determine the preset number of cycles based on the preset temperature or the preset temperature range of the test scenario, or based on the preset temperature or the preset temperature range, and the preset humidity or the preset humidity range of the test scenario. Thus, by associating the preset number of cycles of the test scenario with the temperature condition or the humidity condition, a correlation can be established between the preset number of cycles and the environmental quality of the actual application scenario of the electrochromic product, making the test more closely aligned with the actual application scenario and fully verifying the operational reliability of the electrochromic product in the actual application scenario.

[0037] Optionally, the main control device is specifically configured to: determine the total number of cycles of the charge-discharge cycle test of the electrochromic product; determine the percentage of charge-discharge cycle tests performed in the test scenario based on a preset temperature or a preset temperature range of the test scenario, or based on a preset temperature or a preset temperature range and a preset humidity or a preset humidity range of the test scenario; and determine the preset number of cycles based on the total number of cycles and the percentage of cycles. Thus, by determining the total number of cycles and then determining the preset number of cycles for each test scenario based on the total number of cycles and the percentage of cycles, the main control device can ensure that the percentage of each test scenario closely matches the frequency of occurrence of each application scenario, further fully verifying the operational reliability of the electrochromic product in actual application scenarios.

Thus, by associating the total number of cycles with the expected service life and the expected average daily number of color changes of the electrochromic product, the test can be made more closely aligned with actual application scenarios, further fully verifying the operational reliability of the electrochromic product in actual application scenarios.

[0039] Optionally, when the test scenario includes at least one of the highest temperature scenario, the high temperature scenario, the low temperature scenario, and the sub-high temperature and high humidity scenario, the number of times meets at least one of the following conditions: the number of times the charge and discharge cycle test is performed in the highest temperature scenario accounts for no less than 10%, the number of times the charge and discharge cycle test is performed in the high temperature scenario accounts for no less than 10%, the number of times the charge and discharge cycle test is performed in the low temperature scenario accounts for no less than 10%, and the number of times the charge and discharge cycle test is performed in the sub-high temperature and high humidity scenario accounts for no less than 10%. Thus, in the test process of the electrochromic product, by ensuring that the number of tests in various extreme environments (such as the highest temperature scenario, the high temperature scenario, the low temperature scenario, and the sub-high temperature and high humidity scenario, etc.) meets certain proportion requirements, on the one hand, the test can be made closer to the actual application scenario, and on the other hand, the test requirements for the electrochromic product can be further improved, thereby not only ensuring the working reliability of the electrochromic product in the actual application scenario, but also improving the life of the electrochromic product in actual use.

[0040] Optionally, the test scenarios include at least two of a mild scenario, a maximum temperature scenario, a high temperature scenario, a low temperature scenario, and a medium temperature and high humidity scenario. The main control device is used to determine the test parameters corresponding to the environmental characteristics of the different test scenarios; the tester is used to perform charge and discharge cycle tests on the electrochromic product according to the charge and discharge parameters in the different test scenarios. Preferably, the main control device is used to perform charge and discharge cycles on the electrochromic product according to the charge and discharge parameters in the different test scenarios until the number of charge and discharge cycles reaches the preset number of cycles corresponding to the different test scenarios. In this way, it is possible to select multiple appropriate test scenarios based on the actual application scenario requirements of the electrochromic product, and subject the same electrochromic product to charge and discharge cycles in different test scenarios, that is, to perform serial charge and discharge cycle tests on the electrochromic product. This can make the testing process more closely aligned with the actual application scenario, thereby better considering the actual performance of the electrochromic product in different application scenarios, and facilitate a more comprehensive understanding of the color change performance and working stability of the electrochromic product.

[0041] Optionally, the test scenario includes at least one of a mild scene, a maximum temperature scene, a high temperature scene, a low temperature scene, and a sub-high temperature and high humidity scene; the environmental characteristics of the test scenario include a preset temperature or a preset temperature range, wherein the preset temperature or preset temperature range of the maximum temperature scene is greater than the preset temperature or preset temperature range of the high temperature scene, the preset temperature or preset temperature range of the high temperature scene is greater than the preset temperature or preset temperature range of the sub-high temperature and high humidity scene, the preset temperature or preset temperature range of the sub-high temperature and high humidity scene is greater than the preset temperature or preset temperature range of the mild scene, and the preset temperature or preset temperature range of the mild scene is greater than the preset temperature or preset temperature range of the low temperature scene; and the charge and discharge parameters include at least one of a first charge and discharge parameter, a second charge and discharge parameter, a third charge and discharge parameter, and a fourth charge and discharge parameter; the preset number of cycles includes at least one of a first preset number of cycles, a second preset number of cycles, a third preset number of cycles, and a fourth preset number of cycles; and the test system includes at least one of the following:

[0042] The main control device is specifically used to determine the first charge and discharge parameters and the first preset number of cycles corresponding to the environmental characteristics of the highest temperature scene or the high temperature scene; the tester is specifically used to perform a first charge and discharge cycle on the electrochromic product according to the first charge and discharge parameters until the number of the first charge and discharge cycles reaches the first preset number of cycles;

[0043] The main control device is specifically used to determine the second charge and discharge parameters and the second preset number of cycles corresponding to the environmental characteristics of the mild scene; the tester is specifically used to perform a second charge and discharge cycle on the electrochromic product according to the second charge and discharge parameters until the number of the second charge and discharge cycles reaches the second preset number of cycles;

[0044] The main control device is specifically used to determine a third charge and discharge parameter and a third preset number of cycles corresponding to the environmental characteristics of the low-temperature scene; the tester is specifically used to perform a third charge and discharge cycle on the electrochromic product according to the third charge and discharge parameter until the number of the third charge and discharge cycles reaches the third preset number of cycles;

[0045] The main control device is specifically used to determine the fourth charge and discharge parameters and the fourth preset number of cycles corresponding to the environmental characteristics of the secondary high temperature and high humidity scene; the tester is specifically used to perform a fourth charge and discharge cycle on the electrochromic product according to the fourth charge and discharge parameters until the number of the fourth charge and discharge cycles reaches the fourth preset number of cycles.

[0046] In this case, the electrochromic product can be tested individually in only one test scenario, or it can be tested serially in multiple test scenarios, depending on the requirements of the actual application scenario of the electrochromic product, so that the testing process is closer to the actual application scenario.

[0047] Preferably, the main control device is specifically used to: first, determine the first charge and discharge parameters and the first preset number of cycles corresponding to the environmental characteristics of the highest temperature scene or the high temperature scene, and / or, determine the third charge and discharge parameters and the third preset number of cycles corresponding to the environmental characteristics of the low temperature scene, and / or, determine the fourth charge and discharge parameters and the fourth preset number of cycles corresponding to the environmental characteristics of the secondary high temperature and high humidity scene; the tester is specifically used to: first, perform a first charge and discharge cycle on the electrochromic product according to the first charge and discharge parameters until the number of the first charge and discharge cycles reaches the first preset number of cycles, and / or, perform a third charge and discharge cycle on the electrochromic product according to the third charge and discharge parameters until the number of the third charge and discharge cycles reaches the third preset number of cycles, and / or, perform a fourth charge and discharge cycle on the electrochromic product according to the fourth charge and discharge parameters until the number of the fourth charge and discharge cycles reaches the fourth preset number of cycles. The main control device is specifically configured to: then determine the second charge-discharge parameters and the second preset number of cycles corresponding to the environmental characteristics of the mild scenario; and the tester is specifically configured to: then perform a second charge-discharge cycle on the electrochromic product based on the second charge-discharge parameters until the number of the second charge-discharge cycles reaches the second preset number of cycles. In this case, because electrochromic products are significantly affected by the environment (especially harsh environments), during the testing of the electrochromic product, by first subjecting it to a charge-discharge cycle in an extreme scenario (e.g., at least one of a maximum temperature scenario, a high temperature scenario, a low temperature scenario, and a sub-high temperature and high humidity scenario) and then to a charge-discharge cycle in a mild scenario, any defects in the electrochromic product itself can be identified more quickly during the early testing process, eliminating the need for subsequent charge-discharge cycles in a mild scenario, thereby saving testing time.

The main control device is specifically used to: then determine the first charge and discharge parameters and the first preset number of cycles corresponding to the environmental characteristics of the highest temperature scene or the high temperature scene, and / or determine the third charge and discharge parameters and the third preset number of cycles corresponding to the environmental characteristics of the low temperature scene, and / or determine the fourth charge and discharge parameters and the fourth preset number of cycles corresponding to the environmental characteristics of the secondary high temperature and high humidity scene; the tester is specifically used to: then perform a first charge and discharge cycle on the electrochromic product according to the first charge and discharge parameters until the number of the first charge and discharge cycles reaches the first preset number of cycles, and / or perform a third charge and discharge cycle on the electrochromic product according to the third charge and discharge parameters until the number of the third charge and discharge cycles reaches the third preset number of cycles, and / or perform a fourth charge and discharge cycle on the electrochromic product according to the fourth charge and discharge parameters until the number of the fourth charge and discharge cycles reaches the fourth preset number of cycles. In this way, the entire testing process can be made closer to the actual application scenarios of the electrochromic product, improving the validity and reliability of the test results.

[0049] Optionally, the tester is further used to: in a storage scenario, leave the electrochromic product stationary for a preset time; wherein the storage scenario includes at least one of a mild scenario, a maximum temperature scenario, a high temperature scenario, a low temperature scenario, and a sub-high temperature and high humidity scenario, wherein the preset temperature or preset temperature range of the maximum temperature scenario is greater than the preset temperature or preset temperature range of the high temperature scenario, the preset temperature or preset temperature range of the high temperature scene is greater than the preset temperature or preset temperature range of the sub-high temperature and high humidity scene, the preset temperature or preset temperature range of the sub-high temperature and high humidity scene is greater than the preset temperature or preset temperature range of the mild scenario, and the preset temperature or preset temperature range of the mild scene is greater than the preset temperature or preset temperature range of the low temperature scene. Thus, by leaving the electrochromic product stationary in a storage scenario, the static stability of the electrochromic product in each storage scenario can be tested to obtain the static performance and static stability of the electrochromic product.

[0050] Optionally, at least one of the maximum temperature scene, the high temperature scene, the sub-high temperature and high humidity scene, the mild scene, and the low temperature scene satisfies the following conditions: the preset temperature or preset temperature range of the maximum temperature scene is within a range greater than or equal to 70°C, the preset temperature or preset temperature range of the high temperature scene is between 55°C and 70°C, the preset temperature or preset temperature range of the sub-high temperature and high humidity scene is between 35°C and 55°C, the preset humidity or preset humidity range of the sub-high temperature and high humidity scene is between 70%RH and 100%RH, the preset temperature or preset temperature range of the mild scene is between 10°C and 35°C, and the preset temperature or preset temperature range of the low temperature scene is within a range less than or equal to 10°C. Thus, the temperature or humidity corresponding to each test scene can be adaptively adjusted according to the needs of the actual application scenario, so that the test of the electrochromic product is more in line with the actual application scenario, and the applicability and reliability of the test method can be further improved.

It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0061] The following explains the terms that may appear in the embodiments of the present application.

[0062] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three possible relationships exist.

[0064] In the embodiments of the present application, the terms "first," "second," "third," and similar expressions are used only for descriptive purposes to distinguish objects, such as substances, from one another, and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. For example, without departing from the scope of the embodiments of the present application, the first XX can also be referred to as the second XX, and similarly, the second XX can also be referred to as the first XX. Thus, features defined as "first," "second," or "third" can explicitly or implicitly include one or more of such features.

[0066] In the embodiment of the present application, the term "stationary" may include a situation where the electrochromic product is not in the charging or discharging process, that is, a situation where no voltage or current is applied to the electrochromic product, and may also include a situation where the state of the electrochromic product (such as color or transmittance) is maintained unchanged.

[0067] In application, the testing method for electrochromic products provided in the embodiments of the present application is applied to electrochromic products. The electrochromic products can specifically be dimmable glass suitable for buildings, anti-glare interior / exterior rearview mirrors, color-changing windshields, color-changing windows or color-changing panoramic skylights suitable for automobiles, color-changing goggles or virtual-reality glasses, or housings of electronic devices, etc. The embodiments of the present application do not impose any restrictions on the specific types of electrochromic products.

[0068] It should be understood that in the various embodiments of the present application, the size of the serial number of each process does not mean the order of execution. Some or all steps can be executed in parallel or sequentially. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0069] The technical solutions of the embodiments of the present application will be described below with reference to the accompanying drawings.

[0070] FIG1 shows a schematic diagram of the architecture of a test system 100 for an electrochromic product provided in an embodiment of the present application. The test system 100 includes a main control device 101 and a tester 102. The main control device 101 and the tester 102 are connected; wherein,

[0071] The main control device 101 is used to determine the test parameters corresponding to the environmental characteristics of the test scene, and the test parameters include charge and discharge parameters;

[0072] The tester 102 is used to perform a charge-discharge cycle test on the electrochromic product 103 according to the charge-discharge parameters.

[0073] In the embodiment of the present application, the main control device 101 can be a mobile phone, a tablet computer, a wearable device, a laptop computer, a desktop computer, an ultra-mobile personal computer (UMPC), a personal digital assistant (PDA), etc. The embodiment of the present application does not impose any restrictions on the specific type of the main control device 101. The main control device 101 can match corresponding test parameters according to the environmental characteristics of the test scene, and the test parameters include the charge and discharge parameters of the electrochromic product 103.

[0074] In an embodiment of the present application, the electrochromic product 103 can be placed in a test box or circulation cabinet or laboratory that supports adjustment of environmental characteristics such as temperature and / or humidity for charge and discharge cycle testing, or the tester 102 itself is the above-mentioned test box or circulation cabinet or laboratory, and the tester 102 is connected to the main control device 101 and the electrochromic product 103 respectively, and drives the electrochromic product 103 according to the received charge and discharge parameters under the control of the main control device 101 to perform charge and discharge cycle testing on the electrochromic product 103.

[0075] In this case, the main control device determines the corresponding test parameters according to the scene characteristics of the test scene. The test parameters include charge and discharge parameters. The tester performs a cycle test on the electrochromic product according to the charge and discharge parameters. Through the cooperation of the main control device and the tester, the charge and discharge cycle test of the electrochromic product in the test scene can be realized. In this way, the working stability of the electrochromic product in the corresponding test scene can be verified, which is beneficial for developers to match the scene with the charge and discharge parameters, thereby improving the service life of the electrochromic product after leaving the factory.

[0076] In some embodiments, the main control device 101 can build a corresponding test scene according to the environmental characteristics before obtaining the corresponding test parameters according to the environmental characteristics, or after obtaining the corresponding test parameters according to the environmental characteristics and before performing the charge and discharge cycle test, and can also place the electrochromic product 103 in the test scene so that the temperature of the electrochromic product 103 itself is the same as the temperature of the test scene.

[0077] In some embodiments, the charge and discharge parameters include charge parameters and discharge parameters, wherein the charge parameters include charge voltage or charge current, and at least one of charge cutoff current, charge cutoff time, and charge cutoff capacity; the discharge parameters include discharge voltage or discharge current, and at least one of discharge cutoff current, discharge cutoff time, and discharge cutoff capacity. In other embodiments, the charge parameters include charge voltage and charge current, and at least one of charge cutoff current, charge cutoff time, and charge cutoff capacity; the discharge parameters include discharge voltage and discharge current, and at least one of discharge cutoff current, discharge cutoff time, and discharge cutoff capacity. In this way, the main control device can determine the charging and discharging parameters according to the environmental characteristics of the test scene, including both charging parameters and discharging parameters, so that the tester can charge and discharge the electrochromic product according to the charging parameters and discharging parameters respectively, that is, perform a charge and discharge cycle test on the electrochromic product; and, by making the charging parameters include the charging voltage and / or charging current, and making the discharging parameters include the discharge voltage and / or discharge current, the tester can charge and discharge the electrochromic product based on voltage or current, simplifying and more effectively controlling the charge and discharge cycle process, and by selecting one of the three cut-off modes of cut-off current, cut-off time and cut-off capacity, the applicability of the test method can also be improved.

[0078] In yet other embodiments, the charging parameters include a charging voltage and a charge cutoff capacity, and the discharging parameters include a discharge voltage and a discharge cutoff current. Thus, by including the charging parameters in terms of the charging voltage and the charge cutoff current, and the discharging parameters in terms of the discharge voltage and the discharge cutoff current, the process of charging and discharging tests on electrochromic products can be simplified, improving testing efficiency.

[0079] In some other embodiments, the charging parameters include a charging voltage and a charging cutoff current, and the discharging parameters include a discharging voltage and a discharging cutoff current. Thus, by making the charging parameters include the charging voltage and the charging cutoff capacity, and making the discharging parameters include the discharging voltage and the discharging cutoff current, the tester can respectively adopt the charging capacity cutoff (charging charge amount) and the discharging current cutoff methods during the charging and discharging processes, which can make the transmittance of the electrochromic product during the cycle test relatively more stable, more in line with the user's usage requirements during the actual use of the electrochromic product, and thus further improve the effectiveness and accuracy of the cycle test.

[0080] It should be noted that for the electrochromic product 103, under different environmental characteristics, the charge / discharge voltage, charge / discharge cutoff current, etc. that the electrochromic product 103 can bear may be different; and under different environmental characteristics, when the same voltage or current is used for color change control, the color change time may also be different (the color change time can be adjusted by configuring the charge / discharge cutoff time and the charge / discharge cutoff capacity). Therefore, when performing a charge and discharge cycle test on the electrochromic product 103, at least two sub-parameters of the charging parameters and / or at least two sub-parameters of the discharge parameters can be determined based on the environmental characteristics, thereby more effectively testing the color change control of the electrochromic product, comprehensively measuring the comprehensive performance of the electrochromic product, and improving test flexibility and test confidence.

[0081] In some embodiments, the charging parameters may further include a maximum charging current. In other embodiments, the discharging parameters may further include a maximum discharging current. Thus, during the charging and discharging process of the electrochromic product, by monitoring the current during the charging process or the current during the discharging process in real time and controlling the real-time current within the threshold of the maximum charging current or the maximum discharging current, it is possible to prevent damage to the electrochromic product caused by excessive current during the charging and discharging process, thereby improving the reliability and stability of the test.

[0082] In some embodiments, the environmental characteristics of the test scenario include a preset temperature or a preset temperature range. The method for the main control device 101 to determine the charge and discharge parameters according to the environmental characteristics may include any one of the following:

[0083] (1) Determine the charge and discharge parameters based on the correspondence between the preset temperature or preset temperature range of the test scenario and the charge and discharge parameters. Specifically, the main control device 101 may pre-store a first comparison table or a first mapping function, and the first comparison table or the first mapping function may include the correspondence between the preset temperature or the preset temperature range and the charge and discharge parameters. By inputting the preset temperature or the preset temperature range into the first comparison table or the first mapping function, the corresponding charge and discharge parameters can be obtained. The embodiment of the present application does not impose any restrictions on the specific correspondence between the preset temperature or the preset temperature range and the charge and discharge parameters. Therefore, the main control device can directly determine the parameters for charging and discharging the electrochromic product based on the direct correspondence between the preset temperature or the preset temperature range and the charge and discharge parameters, thereby simplifying the entire test process and improving the test efficiency.

[0084] (2) According to the preset temperature or preset temperature range of the test scene, determine the temperature interval corresponding to the preset temperature or preset temperature range; and determine the charge and discharge parameters based on the temperature interval and the correspondence between the temperature interval and the charge and discharge parameters. Specifically, the main control device 101 can pre-store a second comparison table or a second mapping function, and the second comparison table or the second mapping function can contain the correspondence between the temperature interval and the charge and discharge parameters. By determining the temperature interval according to the preset temperature or preset temperature range of the test scene, and inputting the temperature interval into the second comparison table or the second mapping function, the corresponding charge and discharge parameters can be obtained. The embodiment of the present application does not impose any restrictions on the specific correspondence between the temperature interval and the charge and discharge parameters. Therefore, the main control device can first determine the temperature interval in which the preset temperature or preset temperature range corresponding to the scene falls, and then select the charge and discharge parameters corresponding to the temperature interval as the test parameters, which can simplify the setting of the charge and discharge parameters, that is, the charge and discharge parameters only need to be set based on different temperature intervals, and do not need to be set separately based on multiple temperatures in the same temperature interval, thereby simplifying the operation process of the test device and helping to improve the stability and reliability of the use of the test device.

[0085] (3) According to the preset temperature or preset temperature range of the test scene, determine the temperature interval corresponding to the preset temperature or preset temperature range; based on the temperature interval and the corresponding relationship between the temperature interval and the transmittance change interval, determine the transmittance change interval of the electrochromic product 103; and determine the charge and discharge parameters according to the transmittance change interval and the corresponding relationship between the transmittance change interval and the charge and discharge parameters. Specifically, the main control device 101 can pre-store a third comparison table or a third mapping function, and a fourth comparison table or a fourth mapping function. The third comparison table or the third mapping function can include the corresponding relationship between the temperature interval and the transmittance change interval, and the fourth comparison table or the fourth mapping function can include the corresponding relationship between the transmittance change interval and the charge and discharge parameters. By determining the temperature interval according to the preset temperature or the preset temperature range of the test scene, and inputting the temperature interval into the third comparison table or the third mapping function, the corresponding transmittance change interval is obtained, and the transmittance change interval is input into the fourth comparison table or the fourth mapping function, the corresponding charge and discharge parameters can be obtained. Generally speaking, in combination with actual scenarios, in scenarios with higher temperatures, such as the highest temperature scenario, high temperature scenario, or medium temperature and high humidity scenario, because the temperature is higher, in most cases, users prefer the electrochromic product to have a lower transmittance to block external light and reduce the heat radiation caused by the light. Therefore, in scenarios with higher temperatures, the transmittance variation range of the electrochromic product can be set closer to the direction with lower transmittance; in scenarios with lower temperatures, such as low temperature scenario, low temperature and high humidity scenario, because the temperature is lower, in most cases, users prefer the electrochromic product to have a higher transmittance to allow more external light to pass through to increase the heat radiation caused by the light. Therefore, in scenarios with lower temperatures, the transmittance variation range of the electrochromic product can be set closer to the direction with higher transmittance; in scenarios with normal temperatures, such as scenarios close to room temperature, mild scenarios, etc., the transmittance variation range can be set to any range between the minimum transmittance and the maximum transmittance. The embodiments of the present application do not impose any restrictions on the specific correspondence between temperature ranges and transmittance variation ranges.

[0086] Taking into account the influence of temperature on the transmittance variation range of electrochromic products, the main control device determines different transmittance variation ranges corresponding to different temperature ranges, and then determines the charge and discharge parameters based on the transmittance variation ranges. Thus, when the charge and discharge cycle test of the electrochromic product is performed using the charge and discharge parameters determined by the method described in (3) above, the transmittance variation results of the electrochromic product can be made more reliable, thereby improving the user experience. Moreover, by separately considering the transmittance variation ranges corresponding to different temperature ranges, the electrochromic product can be prevented from being overcharged or over-discharged at the preset temperature or within the preset temperature range of the test scene, thereby further improving the stability and reliability of the cycle test of the electrochromic product.

[0087] For example, the relationship between the charge and discharge parameters, the temperature range, and the transmittance variation range can be shown in Table 1. In the temperature ranges shown in Table 1, the "-" sign in front of each value indicates a negative value, that is, a sub-zero temperature. For example, a temperature of -10°C indicates a temperature of -10°C. In the discharge parameters shown in Table 1, the "-" sign in front of each value does not indicate a negative value, but only indicates that the charge and discharge direction is the discharge direction. For example, a discharge voltage of -0.6V indicates a discharge voltage of 0.6V, a discharge current of -600mA indicates a discharge current of 600mA, a discharge cut-off current of -40mA indicates a discharge cut-off current of 40mA, and a discharge cut-off time of -200s indicates a discharge cut-off time of 200s. The transmittance variation range can be reflected as a variation range of transmittance gears. In the transmittance gear variation range shown in Table 1, a larger gear indicates a lower transmittance, and a lower gear indicates a higher transmittance.

[0088] Table 1

[0089] In some embodiments, each temperature may also directly correspond to a set of charging parameters or discharging parameters, so that the corresponding charging parameters or discharging parameters may be directly determined according to a preset temperature or a preset temperature range of the test scenario.

[0090] In embodiments of the present application, charge and discharge parameters may include charge parameters and / or discharge parameters. In some embodiments, the charge parameters may include charge voltage and at least one of charge cutoff current, charge cutoff time, and charge cutoff capacity; the discharge parameters may include discharge voltage and at least one of discharge cutoff current, discharge cutoff time, and discharge cutoff capacity. In other embodiments, the charge parameters may include charge current and at least one of charge cutoff current, charge cutoff time, and charge cutoff capacity; the discharge parameters may include discharge current and at least one of discharge cutoff current, discharge cutoff time, and discharge cutoff capacity. In still other embodiments, the charge parameters may include charge voltage and charge current and at least one of charge cutoff current, charge cutoff time, and charge cutoff capacity; the discharge parameters may include discharge voltage and discharge current and at least one of discharge cutoff current, discharge cutoff time, and discharge cutoff capacity. In still other embodiments, the charge parameters may include charge voltage and charge cutoff current, and the discharge parameters may include discharge voltage and discharge current. In still other embodiments, the charge parameters may include charge voltage and charge cutoff current, and the discharge parameters may include discharge voltage and discharge cutoff current. In still other embodiments, the charge parameters may include charge voltage and charge cutoff capacity, and the discharge parameters may include discharge voltage and discharge cutoff current.

[0091] Thus, the charge and discharge parameters determined by the main control device according to the environmental characteristics of the test scene can include both charging parameters and discharging parameters, so that the tester can charge and discharge the electrochromic product according to the charging parameters and discharging parameters respectively, that is, perform a charge and discharge cycle test on the electrochromic product; and, by making the charging parameters include the charging voltage and / or charging current, and making the discharging parameters include the discharge voltage and / or discharge current, the tester can charge and discharge the electrochromic product based on the voltage or current, simplifying and more effectively controlling the charge and discharge cycle process, and by selecting one of the three cut-off modes of cut-off current, cut-off time and cut-off capacity, the applicability of the test method can be improved; further By making the charging parameters include the charging voltage and the charging cut-off current, and the discharging parameters include the discharge voltage and the discharge cut-off current, the process of charging and discharging tests on electrochromic products can be simplified and the test efficiency can be improved; further, by making the charging parameters include the charging voltage and the charging cut-off capacity, and the discharging parameters include the discharge voltage and the discharge cut-off current, the tester can adopt the charging capacity cut-off (charging charge amount) and the discharge current cut-off methods during the charging and discharging processes respectively, which can make the transmittance of the electrochromic product during the cycle test relatively more stable, more in line with the user's usage needs during the actual use of the electrochromic product, etc., thereby further improving the effectiveness and accuracy of the cycle test.

[0092] In some embodiments, the charge and discharge parameters (charge parameters and / or discharge parameters) may be determined entirely based on a preset temperature or a preset temperature range of the test scenario. In other embodiments, the charge and discharge parameters (charge parameters and / or discharge parameters) may be determined partially based on a preset temperature or a preset temperature range of the test scenario, and partially not based on a preset temperature or a preset temperature range of the test scenario. For example, the charging voltage, charging cutoff current, and charging cutoff time in the charging parameters can be determined based on the preset temperature or preset temperature range of the test scenario. For example, when the temperatures corresponding to different test scenarios are different, the charging voltage, charging cutoff current, and charging cutoff time corresponding to each scenario can be different or partially the same, while the charging current can be determined not based on the preset temperature or preset temperature range of the test scenario, for example, one or more preset specific values ​​that are not associated with the temperature; the discharge voltage, discharge cutoff current, and discharge cutoff time in the discharge parameters can be determined based on the preset temperature or preset temperature range of the test scenario. For example, when the temperatures corresponding to different test scenarios are different, the discharge voltage, discharge cutoff current, and discharge cutoff time corresponding to each scenario can be different or partially the same, while the discharge current can be determined not based on the preset temperature or preset temperature range of the test scenario, for example, one or more preset specific values ​​that are not associated with the temperature. Thus, different charging and discharging parameters (charging parameters and / or discharging parameters) can be set according to actual application scenarios to meet different testing requirements.

[0093] In some embodiments, the environmental characteristics of the test scenario include a preset temperature or a preset temperature range, and the test scenario may include at least one of a mild scene, a maximum temperature scene, a high temperature scene, a low temperature scene, and a sub-high temperature and high humidity scene, wherein the preset temperature or preset temperature range of the maximum temperature scene is greater than the preset temperature or preset temperature range of the high temperature scene, the preset temperature or preset temperature range of the high temperature scene is greater than the preset temperature or preset temperature range of the sub-high temperature and high humidity scene, the preset temperature or preset temperature range of the sub-high temperature and high humidity scene is greater than the preset temperature or preset temperature range of the mild scene, and the preset temperature or preset temperature range of the mild scene is greater than the preset temperature or preset temperature range of the low temperature scene. Thus, the main control device can set the preset temperature or preset temperature range for different test scenarios according to the requirements of different test scenarios.

[0094] In some embodiments, at least one of the highest temperature scene, high temperature scene, sub-high temperature and high humidity scene, mild scene and low temperature scene satisfies the following conditions: the preset temperature or preset temperature range of the highest temperature scene is within a range greater than or equal to 85°C, the preset temperature or preset temperature range of the high temperature scene is between 55°C and 85°C, the preset temperature or preset temperature range of the sub-high temperature and high humidity scene is between 42°C and 55°C, the preset humidity or preset humidity range of the sub-high temperature and high humidity scene is between 80%RH and 100%RH, the preset temperature or preset temperature range of the mild scene is between 0°C and 42°C, and the preset temperature or preset temperature range of the low temperature scene is within a range less than or equal to 0°C. In other embodiments, at least one of the highest temperature scene, the high temperature scene, the sub-high temperature and high humidity scene, the mild scene, and the low temperature scene satisfies the following conditions: the preset temperature or preset temperature range of the highest temperature scene is within a range greater than or equal to 70°C, the preset temperature or preset temperature range of the high temperature scene is between 55°C and 70°C, the preset temperature or preset temperature range of the sub-high temperature and high humidity scene is between 35°C and 55°C, the preset humidity or preset humidity range of the sub-high temperature and high humidity scene is between 70%RH and 100%RH, the preset temperature or preset temperature range of the mild scene is between 10°C and 35°C, and the preset temperature or preset temperature range of the low temperature scene is within a range less than or equal to 10°C. Thus, the temperature or humidity corresponding to each test scene can be adaptively adjusted according to the requirements of the actual application scenario, so that the test of the electrochromic product is more in line with the actual application scenario, and the applicability and reliability of the test method can be further improved.

[0095] In some embodiments, at least one of the highest temperature scene, high temperature scene, sub-high temperature and high humidity scene, mild scene and low temperature scene meets the following conditions: the preset temperature of the highest temperature scene is 85°C or the preset temperature range is (85±5)°C, the preset temperature of the high temperature scene is 65°C or the preset temperature range is (65±5)°C, the preset temperature of the sub-high temperature and high humidity scene is 42°C or 50°C, or the preset temperature range is (42±5)°C, or the preset temperature range is (50±5)°C, the preset humidity of the sub-high temperature and high humidity scene is 95%RH or the preset humidity range is (95±5)%RH, the preset temperature of the mild scene is 23°C or the preset temperature range is (23±5)°C, the preset temperature of the low temperature scene is 10°C or -10°C, or the preset temperature range is (10±5)°C, or the preset temperature range is -(10±5)°C.

[0096] In some embodiments, the test scenarios can include at least two of a mild scenario, a maximum temperature scenario, a high temperature scenario, a low temperature scenario, and a medium temperature and high humidity scenario. The main control device 101 can be used to determine the test parameters corresponding to the environmental characteristics of each test scenario; and the tester 102 can be used to perform charge-discharge cycle tests on the electrochromic product 103 based on the charge-discharge parameters in each test scenario. In other embodiments, the main control device 101 can be used to perform charge-discharge cycles on the electrochromic product 103 based on the charge-discharge parameters in each test scenario until the number of charge-discharge cycles reaches a preset number of cycles corresponding to each test scenario. Thus, multiple appropriate test scenarios can be selected based on the actual application scenario requirements of the electrochromic product, and the same electrochromic product can be subjected to charge-discharge cycles in different test scenarios. This means that serial charge-discharge cycle testing of the electrochromic product can be performed. This makes the testing process more closely aligned with actual application scenarios, thereby better considering the actual performance of the electrochromic product in different application scenarios and facilitating a more comprehensive understanding of the electrochromic product's color change performance and operational stability.

[0097] In some embodiments, when executing the test, each test scene can be switched according to a preset test sequence, or different test scenes can be switched randomly. The preset test sequence can be arranged from first execution to last execution as the highest temperature scene, mild scene, low temperature scene, sub-high temperature and high humidity scene; it can also be mild scene, highest temperature scene, low temperature scene, sub-high temperature and high humidity scene, mild scene; it can also be mild scene, low temperature scene, highest temperature scene, sub-high temperature and high humidity scene, mild scene. Thus, by setting the highest temperature scene and the low temperature scene to be switched in adjacent order in the preset test sequence, and by switching between mild scenes and extreme scenes, rapid cooling and rapid heating temperature tests can be achieved, and the actual performance of electrochromic products under different extreme conditions can be considered, which is beneficial for testers to further understand the performance and working stability of electrochromic products.

[0098] It should be noted that the preset test sequence can be set according to actual application requirements, and the embodiment of the present application does not impose any restrictions on the preset test sequence.

[0099] In some embodiments, the low temperature scene may include a low temperature and high humidity scene and a low temperature and low humidity scene. The embodiments of the present application do not impose any restrictions on the specific types and quantities of the test scenes. The preset temperatures or preset temperature ranges of the low temperature and high humidity scene and the low temperature and low humidity scene may be the same or different. In other embodiments, the preset temperatures or preset temperature ranges of the low temperature and high humidity scene and the low temperature and low humidity scene may be respectively within a range of less than or equal to 10°C. In yet other embodiments, the preset humidity or preset humidity range of the low temperature and high humidity scene may be between 50% RH and 100% RH, and the preset humidity or preset humidity range of the low temperature and low humidity scene may be between 0 and 50% RH.

[0100] In some embodiments, the test parameters may include a preset number of cycles, and the tester 102 may be specifically used to perform charge and discharge cycles on the electrochromic product 103 according to the charge and discharge parameters until the number of charge and discharge cycles reaches the preset number of cycles. The preset number of cycles may be determined based on the environmental characteristics of the test scenario, or may be determined based on the frequency of occurrence of the test scenario in the actual use scenario. Thus, the main control device may determine the corresponding preset number of cycles based on the environmental characteristics of the test scenario. By setting the preset number of cycles, the electrochromic product may be subjected to a charge and discharge cycle test in the corresponding test scenario, and the number of charge and discharge cycles may be monitored. When the number of charge and discharge cycles reaches the preset number of cycles, the tester may be controlled to stop charging and discharging in the scenario. This allows for more effective and comprehensive control of the charge and discharge cycles in the test scenario, preventing situations such as insufficient test times (too short a time) or excessive test times (too long a time).

[0101] It should be noted that charging and discharging the electrochromic product 103 once can be considered to complete a charge-discharge cycle. In some embodiments, the electrochromic product 103 can be charged first and then discharged to complete a charge-discharge cycle. In other embodiments, the electrochromic product 103 can be discharged first and then charged to complete a charge-discharge cycle. In the embodiments of the present application, there is no particular limitation on the order of charging or discharging. Therefore, the electrochromic product can be charged and discharged according to the needs of the actual product and application scenario to improve the applicability of the test method.

[0102] In some embodiments, when the main control device 101 switches between various test scenes according to a preset test sequence, after the number of charge and discharge cycles in any test scene reaches the corresponding preset number of cycles, it switches to the next test scene, and so on, until it switches to the last test scene and the number of charge and discharge cycles reaches the corresponding preset number of cycles, determining that the charge and discharge cycle test of the electrochromic product 103 is completed.

[0103] In some embodiments, the environmental characteristics of the test scene include a preset temperature or a preset temperature range, or the environmental characteristics of the test scene include a preset temperature or a preset temperature range, and a preset humidity or a preset humidity range; the main control device 101 is specifically configured to determine a preset number of cycles based on the preset temperature or preset temperature range of the test scene, or based on the preset temperature or preset temperature range, and the preset humidity or preset humidity range of the test scene. That is, the main control device 101 can determine the preset number of cycles of the electrochromic product based on the temperature and / or humidity of the test scene. Thus, by associating the preset number of cycles of the test scene with the temperature condition or the humidity condition, a correlation can be established between the size of the preset number of cycles and the environmental quality of the actual application scenario of the electrochromic product, making the test closer to the actual application scenario and fully verifying the working reliability of the electrochromic product in the actual application scenario.

[0104] In some embodiments, the main control device 101 can determine the preset number of cycles based on the preset temperature or preset temperature range of the test scene. In this case, the setting logic of the preset number of cycles can be: when the preset temperature or preset temperature range of the test scene exceeds the preset temperature or preset temperature range of the mild scene, the greater the absolute difference between the preset temperature or preset temperature range of the test scene and the preset temperature or preset temperature range of the mild scene, the fewer the preset number of cycles; that is, the more extreme the temperature condition of the test scene, the fewer the preset number of cycles. The setting logic of the preset number of cycles can also be: when the preset temperature or preset temperature range of the test scene exceeds the preset temperature or preset temperature range of the mild scene, the greater the absolute difference between the preset temperature or preset temperature range of the test scene and the preset temperature or preset temperature range of the mild scene, the more the preset number of cycles; that is, the more extreme the temperature condition of the test scene, the more the preset number of cycles.

[0105] In some embodiments, the main control device 101 may determine the preset number of cycles based on the preset temperature or preset temperature range of the test scene, and the preset humidity or preset humidity range. In this case, the setting logic of the preset number of cycles may be: when the preset temperature or preset temperature range of the test scene exceeds the preset temperature or preset temperature range of the mild scene, the greater the absolute difference between the preset temperature or preset temperature range of the test scene and the preset temperature or preset temperature range of the mild scene, the fewer the preset number of cycles; and at the same time, when the preset humidity or preset humidity range of the test scene exceeds the preset humidity or preset humidity range of the mild scene, the greater the absolute difference between the preset humidity or preset humidity range of the test scene and the preset humidity or preset humidity range of the mild scene, the smaller the preset number of cycles; or, when the preset humidity or preset humidity range of the test scene exceeds the preset humidity or preset humidity range of the mild scene, the greater the absolute difference between the preset humidity or preset humidity range of the test scene and the preset humidity or preset humidity range of the mild scene, the larger the preset number of cycles. The setting logic of the preset number of cycles may also be: when the preset temperature or preset temperature range of the test scene exceeds the preset temperature or preset temperature range of the mild scene, the greater the absolute difference between the preset temperature or preset temperature range of the test scene and the preset temperature or preset temperature range of the mild scene, the greater the preset number of cycles; at the same time, when the preset humidity or preset humidity range of the test scene exceeds the preset humidity or preset humidity range of the mild scene, the greater the absolute difference between the preset humidity or preset humidity range of the test scene and the preset humidity or preset humidity range of the mild scene, the preset number of cycles is reduced; or when the preset humidity or preset humidity range of the test scene exceeds the preset humidity or preset humidity range of the mild scene, the greater the absolute difference between the preset humidity or preset humidity range of the test scene and the preset humidity or preset humidity range of the mild scene, the preset number of cycles is increased. It should be noted that the embodiments of the present application do not impose any restrictions on the correspondence between temperature conditions or humidity conditions and the preset number of cycles, and do not impose any restrictions on the specific number of preset number of cycles for any test scene.

[0106] Therefore, by associating the preset number of cycles for each test scenario with temperature conditions or humidity conditions, it is possible to establish a correlation between the size of the preset number of cycles and the environmental quality of the actual application scenario of the electrochromic product, making the test closer to the actual application scenario and fully verifying the working reliability of the electrochromic product in the actual application scenario.

[0107] In some embodiments, the main control device 101 can be specifically used to determine the total number of cycles of the charge and discharge cycle test of the electrochromic product 103; wherein the total number of cycles can be directly determined based on the life requirements of the electrochromic product 103 or the actual application needs of the electrochromic product 103, for example, 20,000 times or 100,000 times. In other embodiments, the main control device 101 can be specifically used to determine the total number of cycles based on the expected service life and the expected average daily color change number of the electrochromic product 103. For example, assuming the expected service life is 5 years and the expected average daily color change number is 3 times, the total number of cycles is 5*3*365=5475 times. In some other embodiments, the minimum number of cycles can also be calculated based on the expected service life and the expected average daily color change number of the electrochromic product 103, and the total number of cycles can be determined based on the pressure test coefficient and the minimum number of cycles. For example, assuming that the minimum number of cycles is 5475 times, when the stress test coefficient is 3 (which can be regarded as increasing the expected average daily number of color changes to 9 times), the total number of cycles is 5475*3=16425 times, or, when the stress test coefficient is 6 (which can be regarded as increasing the expected average daily number of color changes to 9 times and the expected service life to 10 years), the total number of cycles is 5475*6=32850 times.

[0108] In some embodiments, the main control device 101 can be specifically configured to: determine the percentage of charge and discharge cycle tests performed in a test scenario based on a preset temperature or preset temperature range of the test scenario, or based on a preset temperature or preset temperature range and a preset humidity or preset humidity range of the test scenario; and determine the preset number of cycles based on the total number of cycles and the percentage of cycles. The percentage of cycles can be directly determined based on the test scenario requirements. For example, the percentage of cycles for a mild scenario with a temperature between 10°C and 35°C is 50%. Then, the product of the total number of cycles and the percentage of cycles in the test scenario is calculated to determine the preset number of cycles.

[0109] In other embodiments, the main control device 101 can be specifically used to: determine the time proportion of the test scene in the expected service life based on the preset temperature or preset temperature range of the test scene, or based on the preset temperature or preset temperature range, and the preset humidity or preset humidity range of the test scene; and determine the preset number of cycles based on the total number of cycles and the time proportion. In some embodiments, the time proportion of the temperature and / or humidity of the test scene in the expected service life can be monitored, or the time proportion of the temperature and / or humidity of the test scene in a year can be monitored to determine the time proportion of the test scene. For example, by monitoring the expected service life or a year, the time of the highest temperature scene (for example, a temperature of 85°C) accounts for 12% of the expected service life or a year, and the time proportion of the test scene is determined to be 12%. Then, the product of the total number of cycles and the time proportion under the test scene is calculated to determine the preset number of cycles.

[0110] Therefore, by determining the total number of cycles and then determining the preset number of cycles for the test scenario based on the total number of cycles and the percentage of cycles or the percentage of time, the master control device can make the percentage of test scenarios more closely match the frequency of occurrence of each application scenario, fully verifying the operational reliability of the electrochromic product in actual application scenarios. Furthermore, by correlating the total number of cycles with the expected service life and expected average daily number of color changes of the electrochromic product, the test can be made more closely aligned with actual application scenarios, further fully verifying the operational reliability of the electrochromic product in actual application scenarios.

[0111] In some embodiments, when the test scenario includes at least one of a maximum temperature scenario, a high temperature scenario, a low temperature scenario, and a sub-high temperature and high humidity scenario, the number of times satisfies at least one of the following conditions: the number of charge and discharge cycle tests performed in the maximum temperature scenario accounts for no less than 10%, the number of charge and discharge cycle tests performed in the high temperature scenario accounts for no less than 10%, the number of charge and discharge cycle tests performed in the low temperature scenario accounts for no less than 10%, and the number of charge and discharge cycle tests performed in the sub-high temperature and high humidity scenario accounts for no less than 10%.

[0112] In some embodiments, when the test scenario includes the highest temperature scenario, the high temperature scenario, the low temperature scenario, the sub-high temperature and high humidity scenario, and the mild scenario at the same time, the number of times the highest temperature scenario, the high temperature scenario, the low temperature scenario, and the sub-high temperature and high humidity scenario are subjected to the charge and discharge cycle test can all account for 10%, and the number of times the mild scenario is subjected to the charge and discharge cycle test is 60%. When performing the charge and discharge cycle test, multiple rounds of charge and discharge cycle tests can be set. For any test scenario, the number of cycles of each round is determined according to the total number of cycles, the number of rounds, and the number of times of any of the above test scenarios. For example, assuming that the number of rounds is 2, the total number of cycles is 10,000 times, and any of the above test scenarios is the highest temperature scenario, the corresponding number of times or time is 10%, then in each round, the number of cycles of the highest temperature scenario is equal to (10,000 / 2)*10%=500 times. The embodiment of the present application does not impose any restrictions on the number of rounds of charge and discharge cycle tests and the number of times or time of each test scenario.

[0113] In some embodiments, the test scenario includes at least one of a mild scenario, a maximum temperature scenario, a high temperature scenario, a low temperature scenario, and a sub-high temperature and high humidity scenario; the environmental characteristics of the test scenario include a preset temperature or a preset temperature range, wherein the preset temperature or preset temperature range of the maximum temperature scenario is greater than the preset temperature or preset temperature range of the high temperature scenario, the preset temperature or preset temperature range of the high temperature scenario is greater than the preset temperature or preset temperature range of the sub-high temperature and high humidity scenario, the preset temperature or preset temperature range of the sub-high temperature and high humidity scenario is greater than the preset temperature or preset temperature range of the mild scenario, and the preset temperature or preset temperature range of the mild scene is greater than the preset temperature or preset temperature range of the low temperature scene; and the charge and discharge parameter includes at least one of a first charge and discharge parameter, a second charge and discharge parameter, a third charge and discharge parameter, and a fourth charge and discharge parameter; the preset number of cycles includes at least one of a first preset number of cycles, a second preset number of cycles, a third preset number of cycles, and a fourth preset number of cycles; and the test system 100 includes at least one of the following:

[0114] The main control device 101 is specifically configured to determine a first charge-discharge parameter and a first preset number of cycles corresponding to the environmental characteristics of the highest temperature scenario or the high temperature scenario; the tester 102 is specifically configured to perform a first charge-discharge cycle on the electrochromic product 103 according to the first charge-discharge parameter until the number of the first charge-discharge cycles reaches the first preset number of cycles;

[0115] The main control device 101 is specifically configured to determine a second charge-discharge parameter and a second preset number of cycles corresponding to the environmental characteristics of a mild scene; the tester 102 is specifically configured to perform a second charge-discharge cycle on the electrochromic product 103 according to the second charge-discharge parameter until the number of the second charge-discharge cycles reaches the second preset number of cycles;

[0116] The main control device 101 is specifically configured to determine a third charge-discharge parameter and a third preset number of cycles corresponding to the environmental characteristics of a low-temperature scene; the tester 102 is specifically configured to perform a third charge-discharge cycle on the electrochromic product 103 according to the third charge-discharge parameter until the number of the third charge-discharge cycles reaches the third preset number of cycles;

[0117] The main control device 101 is specifically used to determine the fourth charge and discharge parameters and the fourth preset number of cycles corresponding to the environmental characteristics of the secondary high temperature and high humidity scene; the tester 102 is specifically used to perform a fourth charge and discharge cycle on the electrochromic product 103 according to the fourth charge and discharge parameters until the number of the fourth charge and discharge cycles reaches the fourth preset number of cycles.

[0118] In this case, the electrochromic product can be tested individually in only one test scenario, or it can be tested serially in multiple test scenarios, depending on the requirements of the actual application scenario of the electrochromic product, so that the testing process is closer to the actual application scenario.

[0119] In some embodiments, the main control device 101 can be specifically used to: first, determine the first charge and discharge parameters and the first preset number of cycles corresponding to the environmental characteristics of the highest temperature scene or the high temperature scene, and / or, determine the third charge and discharge parameters and the third preset number of cycles corresponding to the environmental characteristics of the low temperature scene, and / or, determine the fourth charge and discharge parameters and the fourth preset number of cycles corresponding to the environmental characteristics of the secondary high temperature and high humidity scene; the tester 102 can be specifically used to: first, perform a first charge and discharge cycle on the electrochromic product 103 according to the first charge and discharge parameters until the number of the first charge and discharge cycles reaches the first preset number of cycles, and / or, perform a third charge and discharge cycle on the electrochromic product 103 according to the third charge and discharge parameters until the number of the third charge and discharge cycles reaches the third preset number of cycles, and / or, perform a fourth charge and discharge cycle on the electrochromic product 103 according to the fourth charge and discharge parameters until the number of the fourth charge and discharge cycles reaches the fourth preset number of cycles.

In this case, because electrochromic products are greatly affected by the environment (especially the harsh environment), during the testing process of the electrochromic product, by first subjecting it to a charge and discharge cycle in an extreme scene (such as at least one of the highest temperature scene, the high temperature scene, the low temperature scene, and the sub-high temperature and high humidity scene), and then subjecting it to a charge and discharge cycle in a mild scene, if the electrochromic product itself has certain defects, they can be identified more quickly during the early testing process, thereby eliminating the need for subsequent charge and discharge cycles in a mild scene, thereby saving testing time.

[0120] In other embodiments, the main control device 101 can be specifically used to: first, determine the second charge and discharge parameters and the second preset number of cycles corresponding to the environmental characteristics of the mild scene; the tester 102 can be specifically used to: first, perform a second charge and discharge cycle on the electrochromic product 103 according to the second charge and discharge parameters, until the number of the second charge and discharge cycles reaches the second preset number of cycles.

In this way, the entire testing process can be made closer to the actual application scenarios of the electrochromic product, improving the validity and reliability of the test results.

[0124] In some embodiments, the master device 101 can determine the corresponding charge and discharge parameters according to the environmental characteristics of each test scenario, and determine the preset number of cycles for each test scenario based on the number of times or time proportion of the charge and discharge cycle test under each test scenario and the total number of cycles. The following examples illustrate the environmental characteristics, charge and discharge parameters, and preset number of cycles of the above four test scenarios:

[0125] Among them, the preset temperature or preset temperature range of the highest temperature scene is greater than or equal to 70°C, the preset temperature or preset temperature range of the high temperature scene is between 55°C and 70°C, the preset temperature or preset temperature range of the medium temperature and high humidity scene is between 35°C and 55°C, and the preset humidity or humidity range is between 70%RH and 100%RH, the preset temperature or preset temperature range of the mild scene is between 10°C and 35°C, and the preset temperature or preset temperature range of the low temperature scene is less than or equal to 10°C; the first charge and discharge parameters to the fourth charge and discharge parameters can refer to the charge and discharge parameters corresponding to each temperature range in Table 1 above, and will not be repeated here.

[0126] Assuming that the total number of cycles is 20,000, and the number of charge and discharge cycles or the time proportion of the highest temperature scene or high temperature scene, medium high temperature and high humidity scene, and low temperature scene are all 10%, then the first preset number of cycles, the third preset number of cycles, and the fourth preset number of cycles are all 2,000, and the third preset number of cycles is 14,000.

[0127] Therefore, according to the actual needs, the electrochromic product 103 can be tested to perform 2000 charge and discharge cycles in the highest temperature scenario, 2000 charge and discharge cycles in the high temperature scenario, 2000 charge and discharge cycles in the medium high temperature and high humidity scenario, 14,000 charge and discharge cycles in the mild scenario, and 2000 charge and discharge cycles in the low temperature scenario. The charge and discharge cycle tests can be performed serially in the above order or other orders.

[0128] In some embodiments, the main control device 101 is further configured to determine a preset time period for the electrochromic product 103 to be left at rest in a storage scenario. In other embodiments, the tester 102 is further configured to leave the electrochromic product 103 at rest for a preset time period in a storage scenario; wherein the storage scenario includes at least one of a mild scenario, a maximum temperature scenario, a high temperature scenario, a low temperature scenario, and a sub-high temperature and high humidity scenario, wherein the preset temperature or preset temperature range of the maximum temperature scenario is greater than the preset temperature or preset temperature range of the high temperature scenario, the preset temperature or preset temperature range of the high temperature scenario is greater than the preset temperature or preset temperature range of the sub-high temperature and high humidity scenario, the preset temperature or preset temperature range of the sub-high temperature and high humidity scenario is greater than the preset temperature or preset temperature range of the mild scenario, and the preset temperature or preset temperature range of the mild scene is greater than the preset temperature or preset temperature range of the low temperature scene.

[0129] In some embodiments, the tester 102 can store the electrochromic product 103 in any storage scenario for static placement, and the static placement time can be equal to a preset duration, which can be 1 minute, 2 minutes, 1 hour, 2 hours, 24 hours, 120 hours, 240 hours, etc. The embodiment of the present application does not impose any restrictions on the specific duration of the preset duration. Among them, static placement can be a situation where the open circuit voltage of the electrochromic product 103 is equal to 0 or no power is applied, that is, no voltage or current is applied to the electrochromic product 103, or static placement can also be a situation where the state (such as color or transmittance) of the electrochromic product 103 remains unchanged, such as being at a preset static transmittance (brightest state, darkest state, or any transmittance).

[0130] In some embodiments, after the static time of the electrochromic product 103 reaches a preset time, the electrochromic product 103 can be powered on and tested. If the power is successfully supplied and the operation is normal, it is determined that the electrochromic product 103 has passed the static test; if the power fails or the operation is abnormal, it is determined that the electrochromic product 103 has not passed the static test.

[0131] Therefore, by placing the electrochromic product in a storage scenario, the static stability of the electrochromic product in the corresponding storage scenario can be tested to obtain the static performance and static stability of the electrochromic product.

[0132] In some embodiments, the main control device 101 can be specifically used to: first, determine the second charge and discharge parameters and the first sub-cycle number corresponding to the environmental characteristics of the mild scene; second, determine the preset time for the electrochromic product 103 to be stationary under the highest temperature scene; third, determine the first charge and discharge parameters and the first preset cycle number corresponding to the environmental characteristics of the high temperature scene; then, determine the third charge and discharge parameters and the third preset cycle number corresponding to the environmental characteristics of the low temperature scene; then, determine the fourth charge and discharge parameters and the fourth preset cycle number corresponding to the environmental characteristics of the secondary high temperature and high humidity scene; finally, determine the second sub-cycle number corresponding to the environmental characteristics of the mild scene, wherein the sum of the first sub-cycle number and the second sub-cycle number is equal to the second preset cycle number. In other embodiments, the tester 102 can be specifically used to: first, perform a second charge and discharge cycle on the electrochromic product 103 according to the second charge and discharge parameters, until the number of the second charge and discharge cycles reaches the first sub-cycle number; second, in the highest temperature scenario, the electrochromic product 103 is left stationary for a preset time; third, perform a first charge and discharge cycle on the electrochromic product 103 according to the first charge and discharge parameters, until the number of the first charge and discharge cycles reaches the first preset cycle number; then, perform a third charge and discharge cycle on the electrochromic product 103 according to the third charge and discharge parameters, until the number of the third charge and discharge cycles reaches the third preset cycle number; then, perform a fourth charge and discharge cycle on the electrochromic product 103 according to the fourth charge and discharge parameters, until the number of the fourth charge and discharge cycles reaches the fourth preset cycle number; then, in the highest temperature scenario, the electrochromic product 103 is left stationary for a preset time; finally, perform a fifth charge and discharge cycle on the electrochromic product 103 according to the second charge and discharge parameters, until the number of the fifth charge and discharge cycles reaches the second sub-cycle number.

[0133] In some embodiments, the main control device 101 can be used to adjust according to the environmental characteristics of the current test scene when it detects that the electrochromic product 103 has a fault, so as to obtain the environmental characteristics of the storage scene; the environmental pressure of the electrochromic product 103 in the fine-tuning scene is less than the environmental pressure of the electrochromic product 103 in the current test scene; the tester 102 is used to leave the electrochromic product 103 stationary for a preset time in the storage scene.

[0134] In some embodiments, the main control device 101 can monitor the electrochromic product 103 during the charge-discharge cycle test, and determine whether a fault has occurred based on the performance of the electrochromic product 103. Specifically, the transmittance of the electrochromic product 103 can be monitored to determine whether it is within the transmittance range corresponding to the current charge-discharge parameters. If not, it is determined that the electrochromic product 103 has failed. Alternatively, the color change rate of the electrochromic product 103 can be monitored to determine whether it is within the color change rate range corresponding to the current charge-discharge parameters. If not, it is determined that the electrochromic product 103 has failed.

[0135] In some embodiments, if an electrochromic product fails during a charge-discharge cycle test, it indicates that the environmental pressure of the current test scenario is too high. The environmental characteristics of the current test scenario can be adjusted to obtain the environmental characteristics of a storage scenario, where the environmental pressure of the storage scenario is less than that of the current test scenario. A static test is then performed on the electrochromic product 103 in the storage scenario using the tester 102. If the electrochromic product 103 passes the static test, it indicates that the electrochromic product 103 can withstand the environmental pressure of the storage scenario in a static state. The main control device 101 can then determine corresponding test parameters based on the environmental characteristics of the storage scenario, and the tester 102 can then perform a charge-discharge cycle test on the electrochromic product 103 based on the corresponding test parameters to determine the dynamic performance and operational stability of the electrochromic product 103 in the storage scenario.

[0136] Therefore, by reducing the environmental pressure of the test scenario in response to the failure of the electrochromic product and conducting static tests and subsequent charge and discharge cycle tests, the ultimate environmental pressure that the electrochromic product can withstand in similar scenarios can be analyzed, which is beneficial for testers to further understand the ultimate performance of the electrochromic product, so as to deeply match the scenario with the charge and discharge parameters, thereby improving the service life of the electrochromic product after leaving the factory.

[0137] The test system for the electrochromic product provided in the embodiment of the present application is described in detail above in conjunction with Figure 1. The test method provided in the embodiment of the present application will be described in detail below in conjunction with Figures 2 to 4. The corresponding methods 200, 300, and 400 shown in Figures 2 to 4 can be executed in a system 100 such as that shown in Figure 1. It should be understood that the description of the test method embodiment corresponds to the description of the test system embodiment. Therefore, for matters not described in detail, please refer to the test system embodiment above. For the sake of brevity, they will not be repeated here.

[0138] FIG2 shows a schematic flow chart of a method 200 for testing an electrochromic product according to an embodiment of the present application.

[0139] As shown in FIG2 , a method 200 for testing an electrochromic product provided in an embodiment of the present application includes step S201 : determining test parameters corresponding to environmental characteristics of a test scene, where the test parameters include charge and discharge parameters; and step S202 : performing a charge and discharge cycle test on the electrochromic product based on the charge and discharge parameters.

[0140] In an embodiment of the present application, corresponding test parameters can be matched according to the environmental characteristics of the test scene. The test parameters include the charge and discharge parameters of the electrochromic product, and the electrochromic product is driven according to the charge and discharge parameters to perform a charge and discharge cycle test on the electrochromic product.

[0141] In some embodiments, the environmental characteristics of the test scene include a preset temperature or a preset temperature range, and the test scene includes at least one of a mild scene, a maximum temperature scene, a high temperature scene, a low temperature scene, and a sub-high temperature and high humidity scene, wherein the preset temperature or preset temperature range of the highest temperature scene is greater than the preset temperature or preset temperature range of the high temperature scene, the preset temperature or preset temperature range of the high temperature scene is greater than the preset temperature or preset temperature range of the sub-high temperature and high humidity scene, the preset temperature or preset temperature range of the sub-high temperature and high humidity scene is greater than the preset temperature or preset temperature range of the mild scene, and the preset temperature or preset temperature range of the mild scene is greater than the preset temperature or preset temperature range of the low temperature scene.

[0142] In some embodiments, at least one of the highest temperature scene, high temperature scene, sub-high temperature and high humidity scene, mild scene and low temperature scene satisfies the following conditions: the preset temperature or preset temperature range of the highest temperature scene is within a range greater than or equal to 85°C, the preset temperature or preset temperature range of the high temperature scene is between 55°C and 85°C, the preset temperature or preset temperature range of the sub-high temperature and high humidity scene is between 42°C and 55°C, the preset temperature or preset temperature range of the mild scene is between 0°C and 42°C, and the preset temperature or preset temperature range of the low temperature scene is within a range less than or equal to 0°C. In other embodiments, at least one of the highest temperature scene, high temperature scene, sub-high temperature and high humidity scene, mild scene and low temperature scene satisfies the following conditions: the preset temperature or preset temperature range of the highest temperature scene is within a range greater than or equal to 70°C, the preset temperature or preset temperature range of the high temperature scene is between 55°C and 70°C, the preset temperature or preset temperature range of the sub-high temperature and high humidity scene is between 35°C and 55°C, the preset temperature or preset temperature range of the mild scene is between 10°C and 35°C, and the preset temperature or preset temperature range of the low temperature scene is within a range less than or equal to 10°C.

[0143] Therefore, according to the needs of the actual application scenario, the temperature or humidity corresponding to each test scenario can be adaptively adjusted to make the test of electrochromic products more in line with the actual application scenario, and the applicability and reliability of the test method can be further improved.

[0144] In some embodiments, at least one of the highest temperature scene, high temperature scene, sub-high temperature and high humidity scene, mild scene and low temperature scene meets the following conditions: the preset temperature of the highest temperature scene is 85°C or the preset temperature range is (85±5)°C, the preset temperature of the high temperature scene is 65°C or the preset temperature range is (65±5)°C, the preset temperature of the sub-high temperature and high humidity scene is 42°C or 50°C, or the preset temperature range is (42±5)°C, or the preset temperature range is (50±5)°C, the preset humidity of the sub-high temperature and high humidity scene is 95%RH or the preset humidity range is (95±5)%RH, the preset temperature of the mild scene is 23°C or the preset temperature range is (23±5)°C, the preset temperature of the low temperature scene is 10°C or -10°C, or the preset temperature range is (10±5)°C, or the preset temperature range is -(10±5)°C.

[0145] In some embodiments, the test scenarios may include at least two of a mild scenario, a maximum temperature scenario, a high temperature scenario, a low temperature scenario, and a sub-high temperature and high humidity scenario. Step S201 may include: determining the test parameters corresponding to the environmental characteristics of different test scenarios respectively; step S202 may include: performing charge and discharge cycle tests on the electrochromic product according to the charge and discharge parameters under different test scenarios.

[0146] In some embodiments, when executing the test, each test scene can be switched according to a preset test sequence, or different test scenes can be switched randomly. The preset test sequence can be arranged from first execution to last execution as the highest temperature scene, mild scene, low temperature scene, sub-high temperature and high humidity scene; it can also be mild scene, highest temperature scene, low temperature scene, sub-high temperature and high humidity scene, mild scene; it can also be mild scene, low temperature scene, highest temperature scene, sub-high temperature and high humidity scene, mild scene. Thus, by setting the highest temperature scene and the low temperature scene to be switched in adjacent order in the preset test sequence, and by switching between mild scenes and extreme scenes, temperature tests of rapid cooling and rapid heating can be achieved, and the actual performance of the electrochromic product surface under different extreme conditions can be considered, which is beneficial for testers to further understand the performance and working stability of the electrochromic product.

[0147] It should be noted that the preset test sequence can be set according to actual application requirements, and the embodiment of the present application does not impose any restrictions on the preset test sequence.

[0148] In some embodiments, the low temperature scene may include a low temperature and high humidity scene and a low temperature and low humidity scene.

[0149] Therefore, by configuring corresponding test parameters according to the scene characteristics of different test scenarios, the test parameters include charge and discharge parameters, and by conducting cycle tests on electrochromic products according to the charge and discharge parameters, the working stability of the electrochromic products in the corresponding test scenarios can be verified, and an in-depth understanding of the reliability performance of the electrochromic products in color-changing operations in different scenarios can be obtained, which is conducive to developers matching the scenarios with charge and discharge parameters, thereby improving the service life of the electrochromic products after leaving the factory.

[0150] In some embodiments, before obtaining the corresponding test parameters based on the environmental characteristics, or after obtaining the corresponding test parameters based on the environmental characteristics and before performing the charge and discharge cycle test, a corresponding test scene can be established according to the environmental characteristics, and the electrochromic product can be placed in the test scene so that the temperature of the electrochromic product itself is the same as the preset temperature of the test scene or falls within the preset temperature range of the test scene.

[0151] In some embodiments, the charge and discharge parameters include charging parameters and discharging parameters, wherein the charging parameters include charging voltage and / or charging current, and at least one of charging cut-off current, charging cut-off time and charging cut-off capacity; the discharging parameters include discharging voltage and / or discharging current, and at least one of discharging cut-off current, discharging cut-off time and discharging cut-off capacity.

[0152] It should be noted that for electrochromic products, under different environmental characteristics, the charge / discharge voltage or current, and charge / discharge cut-off current that the electrochromic product can withstand may be different; and under different environmental characteristics, when the same voltage or current is used for color change control, the color change time may also be different (the color change time can be adjusted by configuring the charge / discharge cut-off time and charge / discharge cut-off capacity). Therefore, when performing charge and discharge cycle tests on electrochromic products, at least one sub-parameter of the charging parameters and / or at least one sub-parameter of the discharge parameters can be determined according to the environmental characteristics, that is, at least one of the charging voltage, charge cut-off current, charge cut-off time, charge cut-off capacity, discharge voltage, discharge cut-off current, discharge cut-off time, and discharge cut-off capacity of the electrochromic product can be determined according to the environmental characteristics, thereby more effectively testing the color change control of electrochromic products under different environmental characteristics, comprehensively measuring the comprehensive performance of electrochromic products, and improving test flexibility and test confidence.

[0153] In some embodiments, the charge and discharge parameters may further include: maximum charge current and maximum discharge current.

[0154] Figure 3 shows another schematic flow chart of the electrochromic product testing method provided in an embodiment of the present application. This method 300 can be understood as an extension of method 200, and can be performed in parallel with method 200 or after method 200.

[0155] As shown in Figure 3, the testing method 300 of the electrochromic product provided in the embodiment of the present application may include step S301: determining the charge and discharge parameters based on the corresponding relationship between the preset temperature or preset temperature range of the test scene and the charge and discharge parameters; step S302: determining the temperature interval corresponding to the preset temperature or preset temperature range according to the preset temperature or preset temperature range of the test scene; step S303: determining the charge and discharge parameters based on the temperature interval and the corresponding relationship between the temperature interval and the charge and discharge parameters; step S304: determining the temperature interval corresponding to the preset temperature or preset temperature range according to the preset temperature or preset temperature range of the test scene; step S305: determining the transmittance change interval of the electrochromic product based on the temperature interval and the corresponding relationship between the temperature interval and the transmittance change interval; step S306: determining the charge and discharge parameters based on the transmittance change interval and the corresponding relationship between the transmittance change interval and the charge and discharge parameters; step S307: performing a charge and discharge cycle test on the electrochromic product according to the charge and discharge parameters.

[0156] In some embodiments, the environmental characteristics of the test scenario include a preset temperature or a preset temperature range. The following describes the method for determining the charge and discharge parameters according to the environmental characteristics in steps S301 to S306:

[0157] (1) Determine the charge and discharge parameters based on the correspondence between the preset temperature or preset temperature range of the test scenario and the charge and discharge parameters. Specifically, a first comparison table or a first mapping function may be pre-stored, and the first comparison table or the first mapping function may include the correspondence between the preset temperature or the preset temperature range and the charge and discharge parameters. By inputting the preset temperature or the preset temperature range into the first comparison table or the first mapping function, the corresponding charge and discharge parameters may be obtained. The embodiment of the present application does not impose any restrictions on the specific correspondence between the preset temperature or the preset temperature range and the charge and discharge parameters. Thus, the parameters for charging and discharging the electrochromic product can be directly determined based on the direct correspondence between the preset temperature or the preset temperature range and the charge and discharge parameters, thereby simplifying the entire test process and improving the test efficiency.

[0158] (2) determining a temperature interval corresponding to the preset temperature or the preset temperature range according to the preset temperature or the preset temperature range of the test scene;

[0159] Based on the temperature interval, and the correspondence between the temperature interval and the charge and discharge parameters, the charge and discharge parameters are determined. Specifically, a second comparison table or a second mapping function can be pre-stored, and the second comparison table or the second mapping function can include the correspondence between the temperature interval and the charge and discharge parameters. By determining the temperature interval according to the preset temperature or preset temperature range of the test scene, and inputting the temperature interval into the second comparison table or the second mapping function, the corresponding charge and discharge parameters can be obtained. The embodiment of the present application does not impose any restrictions on the specific correspondence between the temperature interval and the charge and discharge parameters. Therefore, it is possible to first determine the temperature interval in which the preset temperature or preset temperature range corresponding to the scene falls, and then select the corresponding charge and discharge parameters within the temperature interval as the test parameters, which can simplify the setting of the charge and discharge parameters, that is, the charge and discharge parameters only need to be set based on different temperature intervals, and there is no need to set them separately based on multiple temperatures within the same temperature interval, thereby simplifying the operation process of the test equipment, which is conducive to improving the use stability and reliability of the test equipment.

[0160] (3) According to the preset temperature or preset temperature range of the test scene, determine the temperature interval corresponding to the preset temperature or preset temperature range; based on the temperature interval and the corresponding relationship between the temperature interval and the transmittance change interval, determine the transmittance change interval of the electrochromic product; according to the transmittance change interval and the corresponding relationship between the transmittance change interval and the charge and discharge parameters, determine the charge and discharge parameters. Specifically, a third comparison table or a third mapping function and a fourth comparison table or a fourth mapping function can be pre-stored. The third comparison table or the third mapping function can include the corresponding relationship between the temperature interval and the transmittance change interval, and the fourth comparison table or the fourth mapping function can include the corresponding relationship between the transmittance change interval and the charge and discharge parameters. By determining the temperature interval according to the preset temperature or the preset temperature range of the test scene, and inputting the temperature interval into the third comparison table or the third mapping function, the corresponding transmittance change interval is obtained, and the transmittance change interval is input into the fourth comparison table or the fourth mapping function, the corresponding charge and discharge parameters can be obtained. Generally speaking, in combination with actual scenarios, in scenarios with higher temperatures, such as the highest temperature scenario, high temperature scenario, or medium temperature and high humidity scenario, because the temperature is higher, in most cases, users prefer the electrochromic product to have a lower transmittance to block external light and reduce the heat radiation caused by the light. Therefore, in scenarios with higher temperatures, the transmittance variation range of the electrochromic product can be set closer to the direction with lower transmittance; in scenarios with lower temperatures, such as low temperature scenario, low temperature and high humidity scenario, because the temperature is lower, in most cases, users prefer the electrochromic product to have a higher transmittance to allow more external light to pass through to increase the heat radiation caused by the light. Therefore, in scenarios with lower temperatures, the transmittance variation range of the electrochromic product can be set closer to the direction with higher transmittance; in scenarios with normal temperatures, such as scenarios close to room temperature, mild scenarios, etc., the transmittance variation range can be set to any range between the minimum transmittance and the maximum transmittance. The embodiments of the present application do not impose any restrictions on the specific correspondence between temperature ranges and transmittance variation ranges.

[0161] Taking into account the influence of temperature on the transmittance variation range of electrochromic products, by determining different transmittance variation ranges corresponding to different temperature ranges, and then determining the charge and discharge parameters based on the transmittance variation ranges, when the charge and discharge cycle test of the electrochromic product is performed using the charge and discharge parameters determined by the method described in (3) above, the transmittance variation results of the electrochromic product can be made more reliable, thereby improving the user experience; and, by separately considering the transmittance variation ranges corresponding to different temperature ranges, it can also prevent the electrochromic product from being overcharged or over-discharged at the preset temperature or within the preset temperature range of the test scene, which can further improve the stability and reliability of the cycle test of the electrochromic product.

[0162] The exemplary relationship between the charging parameters and the discharging parameters and the temperature range and the transmittance variation range can be referred to in Table 1 above, which will not be described in detail here.

[0163] In some embodiments, each temperature may also directly correspond to a set of charging parameters or discharging parameters, so that the corresponding charging parameters or discharging parameters may be directly determined according to a preset temperature or a preset temperature range of the test scenario.

[0164] Therefore, electrochromic products can be subjected to comparative tests in test scenarios at different temperatures, comprehensively measuring the reliability performance of electrochromic products at different temperatures and using different charge and discharge parameters, further improving the flexibility and confidence of the test.

[0165] In some embodiments, the charge and discharge parameters (charge parameters and / or discharge parameters) may be determined entirely based on a preset temperature or a preset temperature range of the test scenario. In other embodiments, the charge and discharge parameters (charge parameters and / or discharge parameters) may be determined partially based on a preset temperature or a preset temperature range of the test scenario, and partially not based on a preset temperature or a preset temperature range of the test scenario. For example, the charging voltage, charging cutoff current, and charging cutoff time in the charging parameters can be determined based on the preset temperature or preset temperature range of the test scenario. For example, when the temperatures corresponding to different test scenarios are different, the charging voltage, charging cutoff current, and charging cutoff time corresponding to each scenario can be different or partially the same, while the charging current can be determined not based on the preset temperature or preset temperature range of the test scenario, for example, one or more preset specific values ​​that are not associated with the temperature; the discharge voltage, discharge cutoff current, and discharge cutoff time in the discharge parameters can be determined based on the preset temperature or preset temperature range of the test scenario. For example, when the temperatures corresponding to different test scenarios are different, the discharge voltage, discharge cutoff current, and discharge cutoff time corresponding to each scenario can be different or partially the same, while the discharge current can be determined not based on the preset temperature or preset temperature range of the test scenario, for example, one or more preset specific values ​​that are not associated with the temperature. Thus, different charging and discharging parameters (charging parameters and / or discharging parameters) can be set according to actual application scenarios to meet different testing requirements.

[0166] In some embodiments, the environmental characteristics of the test scene include a preset temperature or a preset temperature range, or the environmental characteristics of the test scene include a preset temperature or a preset temperature range, and a preset humidity or a preset humidity range; before step S307, the method may further include: determining a preset number of cycles based on the preset temperature or preset temperature range of the test scene, or based on the preset temperature or preset temperature range, and the preset humidity or preset humidity range of the test scene. That is, the preset number of cycles of the electrochromic product can be determined based on the temperature and / or humidity of the test scene. Thus, by associating the preset number of cycles of the test scene with the temperature condition or the humidity condition, a correlation can be established between the size of the preset number of cycles and the environmental quality of the actual application scenario of the electrochromic product, making the test more closely aligned with the actual application scenario and fully verifying the working reliability of the electrochromic product in the actual application scenario.

[0167] In some embodiments, the preset number of cycles can be determined based on the preset temperature or preset temperature range of the test scene. In this case, the setting logic of the preset number of cycles can be: when the preset temperature or preset temperature range of the test scene exceeds the preset temperature or preset temperature range of the mild scene, the greater the absolute difference between the preset temperature or preset temperature range of the test scene and the preset temperature or preset temperature range of the mild scene, the fewer the preset number of cycles; that is, the more extreme the temperature condition of the test scene, the fewer the preset number of cycles. The setting logic of the preset number of cycles can also be: when the preset temperature or preset temperature range of the test scene exceeds the preset temperature or preset temperature range of the mild scene, the greater the absolute difference between the preset temperature or preset temperature range of the test scene and the preset temperature or preset temperature range of the mild scene, the more the preset number of cycles; that is, the more extreme the temperature condition of the test scene, the more the preset number of cycles.

[0168] In some embodiments, the preset number of cycles can be determined based on the preset temperature or preset temperature range, and the preset humidity or preset humidity range of the test scene. In this case, the setting logic of the preset number of cycles can be: when the preset temperature or preset temperature range of the test scene exceeds the preset temperature or preset temperature range of the mild scene, the greater the absolute difference between the preset temperature or preset temperature range of the test scene and the preset temperature or preset temperature range of the mild scene, the fewer the preset number of cycles; at the same time, when the preset humidity or preset humidity range of the test scene exceeds the preset humidity or preset humidity range of the mild scene, the greater the absolute difference between the preset humidity or preset humidity range of the test scene and the preset humidity or preset humidity range of the mild scene, the lower the preset number of cycles; or, when the preset humidity or preset humidity range of the test scene exceeds the preset humidity or preset humidity range of the mild scene, the greater the absolute difference between the preset humidity or preset humidity range of the test scene and the preset humidity or preset humidity range of the mild scene, the higher the preset number of cycles. The setting logic of the preset number of cycles may also be: when the preset temperature or preset temperature range of the test scene exceeds the preset temperature or preset temperature range of the mild scene, the greater the absolute difference between the preset temperature or preset temperature range of the test scene and the preset temperature or preset temperature range of the mild scene, the greater the preset number of cycles; at the same time, when the preset humidity or preset humidity range of the test scene exceeds the preset humidity or preset humidity range of the mild scene, the greater the absolute difference between the preset humidity or preset humidity range of the test scene and the preset humidity or preset humidity range of the mild scene, the preset number of cycles is reduced; or when the preset humidity or preset humidity range of the test scene exceeds the preset humidity or preset humidity range of the mild scene, the greater the absolute difference between the preset humidity or preset humidity range of the test scene and the preset humidity or preset humidity range of the mild scene, the preset number of cycles is increased. It should be noted that the embodiments of the present application do not impose any restrictions on the correspondence between temperature conditions or humidity conditions and the preset number of cycles, and do not impose any restrictions on the specific number of preset number of cycles for any test scene.

[0169] Therefore, by associating the preset number of cycles for each test scenario with temperature conditions or humidity conditions, it is possible to establish a correlation between the size of the preset number of cycles and the environmental quality of the actual application scenario of the electrochromic product, making the test closer to the actual application scenario and fully verifying the working reliability of the electrochromic product in the actual application scenario.

[0170] Figure 4 shows another schematic flow chart of the electrochromic product testing method provided in an embodiment of the present application. Method 400 can be understood as an extension of method 300, and method 400 can be performed in parallel with method 300, or can also be performed after method 300.

[0171] As shown in Figure 4, the testing method 400 of the electrochromic product provided in the embodiment of the present application may include step S401: determining the charge and discharge parameters based on the corresponding relationship between the preset temperature or preset temperature range of the test scene and the charge and discharge parameters; step S402: determining the temperature interval corresponding to the preset temperature or preset temperature range based on the preset temperature or preset temperature range of the test scene; step S403: determining the charge and discharge parameters based on the temperature interval and the corresponding relationship between the temperature interval and the charge and discharge parameters; step S404: determining the temperature interval corresponding to the preset temperature or preset temperature range based on the preset temperature or preset temperature range of the test scene; step S405: determining the transmittance change interval of the electrochromic product based on the temperature interval and the corresponding relationship between the temperature interval and the transmittance change interval; step S406: determining the charge and discharge parameters based on the transmittance change interval and the corresponding relationship between the transmittance change interval and the charge and discharge parameters.

[0172] Among them, steps S401 to S406 in method 400 can refer to steps S301 to S306 in method 300, and will not be repeated here.

[0173] The testing method 400 for an electrochromic product provided in an embodiment of the present application may further include step S407: determining the total number of cycles of the charge and discharge cycle test of the electrochromic product; step S408: determining the proportion of the number of charge and discharge cycle tests performed in the test scenario based on the preset temperature or preset temperature range of the test scenario, or based on the preset temperature or preset temperature range, and the preset humidity or preset humidity range of the test scenario; step S409: determining the preset number of cycles based on the total number of cycles and the proportion of the number of cycles.

[0174] In some embodiments, in step S407, the total number of cycles can be directly determined based on the life requirements of the electrochromic product or the actual application requirements of the electrochromic product, for example, 20,000 times or 100,000 times. In other embodiments, the total number of cycles can also be determined based on the expected service life of the electrochromic product and the expected average daily number of color changes. For example, assuming that the expected service life is 5 years and the expected average daily number of color changes is 3 times, the total number of cycles is 5*3*365=5475 times. In some other embodiments, the minimum number of cycles can also be calculated based on the expected service life of the electrochromic product and the expected average daily number of color changes, and the total number of cycles can be determined based on the pressure test coefficient and the minimum number of cycles. For example, assuming that the minimum number of cycles is 5475 times, when the stress test coefficient is 3 (which can be regarded as increasing the expected average daily number of color changes to 9 times), the total number of cycles is 5475*3=16425 times, or, when the stress test coefficient is 6 (which can be regarded as increasing the expected average daily number of color changes to 9 times and the expected service life to 10 years), the total number of cycles is 5475*6=32850 times.

[0175] In some embodiments, after determining the total number of cycles, in step S408, the percentage of cycles can be directly determined based on the test scenario requirements. For example, the percentage of cycles in a mild scenario with a temperature between 10°C and 35°C is 50%. In step S409, the preset number of cycles can be determined by multiplying the total number of cycles by the percentage of cycles in the test scenario.

[0176] In other embodiments, step S408 may also be to determine the time proportion of the test scene in the expected service life based on the preset temperature or preset temperature range of the test scene, or based on the preset temperature or preset temperature range, and the preset humidity or preset humidity range of the test scene. Step S409 may also be to determine the preset number of cycles based on the total number of cycles and the time proportion. In some embodiments, the time proportion of the temperature and / or humidity of the test scene in the expected service life can be monitored, or the time proportion of the temperature and / or humidity of the test scene in a year can be monitored to determine the time proportion of the test scene. For example, by monitoring the expected service life or a year, the occurrence time of the highest temperature scene (for example, a temperature of 85°C) accounts for 12% of the expected service life or a year, and the time proportion of the test scene is determined to be 12%. Then, the product of the total number of cycles and the time proportion under the test scene is calculated to determine the preset number of cycles.

[0177] Therefore, by determining the total number of cycles and determining the preset number of cycles for the test scenario based on the total number of cycles and the proportion of the number of cycles or the proportion of the time, the proportion of the test scenario can be made close to the frequency of occurrence of each application scenario, fully verifying the working reliability of the electrochromic product in the actual application scenario; and, by associating the total number of cycles with the expected service life and the expected average daily number of color changes of the electrochromic product, the test can be made closer to the actual application scenario, further fully verifying the working reliability of the electrochromic product in the actual application scenario.

[0178] In some embodiments, when the test scenario includes at least one of a maximum temperature scenario, a high temperature scenario, a low temperature scenario, and a sub-high temperature and high humidity scenario, the number of times satisfies at least one of the following conditions: the number of charge and discharge cycle tests performed in the maximum temperature scenario accounts for no less than 10%, the number of charge and discharge cycle tests performed in the high temperature scenario accounts for no less than 10%, the number of charge and discharge cycle tests performed in the low temperature scenario accounts for no less than 10%, and the number of charge and discharge cycle tests performed in the sub-high temperature and high humidity scenario accounts for no less than 10%.

[0179] In some embodiments, when the test scenario includes the highest temperature scenario, the high temperature scenario, the low temperature scenario, the sub-high temperature and high humidity scenario, and the mild scenario at the same time, the number of times the highest temperature scenario, the high temperature scenario, the low temperature scenario, and the sub-high temperature and high humidity scenario are subjected to the charge and discharge cycle test can all account for 10%, and the number of times the mild scenario is subjected to the charge and discharge cycle test is 60%. When performing the charge and discharge cycle test, multiple rounds of charge and discharge cycle tests can be set. For any test scenario, the number of cycles of each round is determined according to the total number of cycles, the number of rounds, and the number of times of any of the above test scenarios. For example, assuming that the number of rounds is 2, the total number of cycles is 10,000 times, and any of the above test scenarios is the highest temperature scenario, the corresponding number of times or time is 10%, then in each round, the number of cycles of the highest temperature scenario is equal to (10,000 / 2)*10%=500 times. The embodiment of the present application does not impose any restrictions on the number of rounds of charge and discharge cycle tests and the number of times or time of each test scenario.

[0180] In some embodiments, the test scenario includes at least one of a mild scenario, a maximum temperature scenario, a high temperature scenario, a low temperature scenario, and a sub-high temperature and high humidity scenario, and the environmental characteristics of the test scenario include a preset temperature or a preset temperature range, wherein the preset temperature or preset temperature range of the maximum temperature scenario is greater than the preset temperature or preset temperature range of the high temperature scenario, the preset temperature or preset temperature range of the high temperature scenario is greater than the preset temperature or preset temperature range of the sub-high temperature and high humidity scenario, the preset temperature or preset temperature range of the sub-high temperature and high humidity scenario is greater than the preset temperature or preset temperature range of the mild scenario, and the preset temperature or preset temperature range of the mild scene is greater than the preset temperature or preset temperature range of the low temperature scene; and the charge and discharge parameter includes at least one of a first charge and discharge parameter, a second charge and discharge parameter, a third charge and discharge parameter, and a fourth charge and discharge parameter, and the preset number of cycles includes at least one of a first preset number of cycles, a second preset number of cycles, a third preset number of cycles, and a fourth preset number of cycles. The test method 400 further includes at least one of the following test steps:

[0181] Determining first charge and discharge parameters and a first preset number of cycles corresponding to the environmental characteristics of the highest temperature scene or the high temperature scene; and performing a first charge and discharge cycle on the electrochromic product according to the first charge and discharge parameters until the number of the first charge and discharge cycles reaches the first preset number of cycles;

[0182] Determining a second charge-discharge parameter and a second preset number of cycles corresponding to the environmental characteristics of the mild scene; and performing a second charge-discharge cycle on the electrochromic product according to the second charge-discharge parameter until the number of the second charge-discharge cycles reaches the second preset number of cycles;

[0183] Determining a third charge-discharge parameter and a third preset number of cycles corresponding to the environmental characteristics of the low-temperature scene; and performing a third charge-discharge cycle on the electrochromic product according to the third charge-discharge parameter until the number of the third charge-discharge cycles reaches the third preset number of cycles;

[0184] Determine the fourth charge and discharge parameters and the fourth preset number of cycles corresponding to the environmental characteristics of the secondary high temperature and high humidity scene; and perform a fourth charge and discharge cycle on the electrochromic product according to the fourth charge and discharge parameters until the number of the fourth charge and discharge cycles reaches the fourth preset number of cycles.

[0185] In this case, the electrochromic product can be tested individually in only one test scenario, or it can be tested serially in multiple test scenarios, depending on the requirements of the actual application scenario of the electrochromic product, so that the testing process is closer to the actual application scenario.

[0186] In some embodiments, corresponding charge and discharge parameters can be determined based on the environmental characteristics of each test scenario. The preset number of cycles for each test scenario is determined based on the percentage of charge and discharge cycle tests performed in each test scenario, as well as the total number of cycles. The test sequence for each test scenario is described above in relation to the electrochromic product test system and is not further detailed here.

[0187] In some embodiments, the test method 400 may further include: determining a preset time period for the electrochromic product to be left standing in a storage scenario. In other embodiments, the test method 400 may further include: leaving the electrochromic product standing for a preset time period in a storage scenario. The storage scenario includes at least one of a mild scene, a maximum temperature scene, a high temperature scene, a low temperature scene, and a sub-high temperature and high humidity scene, wherein the preset temperature or preset temperature range of the maximum temperature scene is greater than the preset temperature or preset temperature range of the high temperature scene, the preset temperature or preset temperature range of the high temperature scene is greater than the preset temperature or preset temperature range of the sub-high temperature and high humidity scene, the preset temperature or preset temperature range of the sub-high temperature and high humidity scene is greater than the preset temperature or preset temperature range of the mild scene, and the preset temperature or preset temperature range of the mild scene is greater than the preset temperature or preset temperature range of the low temperature scene.

[0188] In some embodiments, the electrochromic product can be stored in any storage scenario and allowed to rest for a period of time equal to a preset duration, which can be 1 minute, 2 minutes, 1 hour, 2 hours, 24 hours, 120 hours, 240 hours, etc. The embodiments of the present application do not impose any restrictions on the specific duration of the preset duration. The resting state can be when the open circuit voltage of the electrochromic product 103 is equal to 0 or when no power is applied, i.e., when no voltage or current is applied to the electrochromic product 103. Alternatively, the resting state can be when the state (e.g., color or transmittance) of the electrochromic product 103 remains unchanged, such as when the state is at a preset resting transmittance (brightest state, darkest state, or any transmittance).

[0189] In some embodiments, after the electrochromic product has been stationary for a preset period of time, the electrochromic product may be subjected to a power-on test. If the power is successfully supplied and the product operates normally, the electrochromic product is determined to have passed the stationary test. If the power fails or the product operates abnormally, the electrochromic product is determined to have failed the stationary test.

[0190] Therefore, by placing the electrochromic product in a storage scenario, the static stability of the electrochromic product in the corresponding storage scenario can be tested to obtain the static performance and static stability of the electrochromic product.

[0191] In some embodiments, the test method 400 also includes: when a fault is detected in the electrochromic product, adjusting according to the environmental characteristics of the current test scene to obtain the environmental characteristics of the storage scene; the environmental pressure of the electrochromic product in the fine-tuning scene is less than the environmental pressure of the electrochromic product in the current test scene; in the storage scene, the electrochromic product is left stationary for a preset time.

[0192] In some embodiments, an electrochromic product undergoing a charge-discharge cycle test can be monitored, and a malfunction can be determined based on the performance of the electrochromic product. Specifically, the transmittance of the electrochromic product can be monitored to determine if it is within the transmittance range corresponding to the current charge-discharge parameters. If not, a malfunction can be determined. Alternatively, the color change rate of the electrochromic product can be monitored to determine if it is within the color change rate range corresponding to the current charge-discharge parameters. If not, a malfunction can be determined.

[0193] In some embodiments, if an electrochromic product fails during a charge-discharge cycle test, it indicates that the environmental pressure of the current test scenario is too high. The environmental characteristics of the current test scenario can be adjusted to obtain the environmental characteristics of a storage scenario, where the environmental pressure of the storage scenario is less than that of the current test scenario. Furthermore, a static test can be performed on the electrochromic product in the storage scenario. If the electrochromic product passes the static test, it indicates that the electrochromic product can withstand the environmental pressure of the storage scenario in a static state. Furthermore, corresponding test parameters can be determined based on the environmental characteristics of the storage scenario, and a charge-discharge cycle test can be performed on the electrochromic product based on the corresponding test parameters to determine the dynamic performance and operational stability of the electrochromic product in the storage scenario.

[0194] Therefore, by reducing the environmental pressure of the test scenario in response to the failure of the electrochromic product and conducting static tests and subsequent charge and discharge cycle tests, the ultimate environmental pressure that the electrochromic product can withstand in similar scenarios can be analyzed, which is beneficial for testers to further understand the ultimate performance of the electrochromic product, so as to deeply match the scenario with the charge and discharge parameters, thereby improving the service life of the electrochromic product after leaving the factory.

[0195] In step S410, the electrochromic product is charged and discharged in cycles according to the charge and discharge parameters until the number of charge and discharge cycles reaches a preset number of cycles.

[0196] In some embodiments, when switching between test scenes according to a preset test sequence, after the number of charge and discharge cycles in any test scene reaches the corresponding preset number of cycles, the test scene is switched to the next test scene, and so on, until the last test scene is switched to and the number of charge and discharge cycles reaches the corresponding preset number of cycles, it is determined that the charge and discharge cycle test of the electrochromic product is completed.
