Based on the test data recorded by the control module, the control module can send the test data to the processing device (such as the corresponding PC tool) for processing, and the test result of the device to be tested can be obtained after the corresponding data processing device.

[0020] In summary, the present invention can realize automatic whole-machine testing of the device to be tested (such as the first / secondary charging operation, the discharging operation), and the operation is simple. It can effectively simplify the production process, improve the testing efficiency and the testing accuracy, and record the corresponding time during the whole-machine testing process to determine whether the device to be tested meets the requirements. The production data is automatically recorded, and the information can be traced.

[0021] Furthermore, in the battery testing system described in the present invention, the device to be tested also includes a power supply switch, which is electrically connected to the power supply device, the control module and the battery device respectively, and the control module is used to control the connection status between the power supply device and the power supply device through the power supply switch.

[0022] It can be seen from the above description that a corresponding power supply switch is set, and the power supply switch is electrically connected to the control module, the battery device, the functional module and the power supply device respectively. The control module can control the switching state of the power supply switch, so that the power supply device is in a corresponding connection state with the battery device and the functional module respectively. For example, the power supply device can be connected / disconnected with the battery device through the power supply switch, and the power supply device can be connected / disconnected with the functional module through the power supply switch.

[0023] Furthermore, in the battery testing system of the present invention, the device to be tested further includes a functional module, and the functional module is electrically connected to the battery device and the control module.

[0024] In practical applications, the functional modules may include audio, video, indicator light and other modules, which can be set according to actual conditions and are not limited here.

[0025] Furthermore, in the battery testing system of the present invention, the device to be tested also includes a prompt module, the prompt module is electrically connected to the battery device and the control module, and the prompt module is used to give an end prompt after the whole machine test is completed.

[0026] From the above description, it can be known that after the device to be tested finishes the whole machine test (ie, records the charging end time), a prompt is given, such as a liquid crystal display or indicator light display through a prompt module, to prompt that the test is completed.

[0027] Furthermore, the battery testing system of the present invention further comprises a server, wherein the server is communicatively connected to the data processing device, and the server is used to receive and display the test result of the device to be tested.

[0028] In actual applications, after processing the test data to generate the test results, the data processing device will upload the test data and the test results to the server to save them to the factory server, so that the test data and test results of each device to be tested can be viewed in batches.

[0029] Correspondingly, another object of the present invention is to provide a battery testing method, which comprises the following steps: S1: Connecting the device to be tested to a power supply device, and performing a first charging operation on a battery device in the device to be tested until the battery device reaches a fully charged state; S2: End the first charging operation of the battery device, perform a discharging operation on the battery device and record the discharging start time; S3: When the power of the battery device is reduced to a preset power, recording the discharge end time; S4: performing a second charging operation on the battery device, recording the charging start time, and recording the charging end time after the battery device is fully charged; S5: Determine a test result of the device to be tested based on the discharge start time, the discharge end time, the charge start time, and the charge end time.

[0030] In actual applications, after the device to be tested is set to the charge and discharge test state and the device to be tested is connected to the power supply device, the first charging operation can be performed on the battery device in the device to be tested. Specifically: the power supply switch can be controlled by the control module to make the power supply device and the battery device connected, so as to perform the first charging operation on the battery device. When the battery device reaches a full charge state (that is, the power is 100%), a discharge operation is performed. During the discharge operation, if the battery device is close to being exhausted (such as 2%, which can be set according to actual conditions), the discharge end time is recorded. After that, a second charging operation is performed. After the second charging operation is completed, the test data recorded by the control module is sent to the data processing device for processing to obtain the test results of the device to be tested. At the same time, the data processing device will save the test records of the device to be tested. The battery device can be various types of batteries such as lithium batteries.

[0031] From the above description, it can be seen that the beneficial effect of the present invention is that after the device to be tested is connected to the power supply device, the device to be tested is subjected to a whole-machine test, specifically: first, the battery device in the device to be tested is subjected to a first charging operation and a discharging operation in sequence, and the discharge start time and the discharge end time are recorded during the discharge operation. Afterwards, the battery device is subjected to a second charging operation, and during the second charging process, the charging start time and the charging end time are recorded.

[0032] In summary, the present invention can realize automatic whole-machine testing of the device to be tested (such as the first / secondary charging operation, the discharging operation), and the operation is simple. It can effectively simplify the production process, greatly improve the testing efficiency and the testing accuracy, and the test data is automatically recorded during the whole-machine testing process, and the information can be traced.

[0033] Furthermore, in the battery testing method of the present invention, in step S2, the first charging operation of the battery device is ended, and a discharging operation is performed on the battery device, including: The power supply switch of the device to be tested is turned off, and the functional modules in the device to be tested are powered by the battery device to continuously operate the functional modules.

[0034] In practical applications, the end of the first charging operation of the battery device includes: disconnecting the power supply switch of the device to be tested through the control module, so that the power supply device is disconnected from the battery device and the power supply device is disconnected from the power supply module. After that, the discharge operation is performed, specifically: the functional modules in the device to be tested are powered by the battery device to achieve the effect of manually unplugging the power supply, and then the power supply module is continuously operated, such as playing audio, video, radio frequency operation, indicator light, etc. In addition, it should be noted that when starting the discharge operation, the discharge start time needs to be recorded.

[0035] Furthermore, in the battery testing method of the present invention, in step S4, a second charging operation is performed on the battery device, including: The functional module is turned off, a power supply switch of the device to be tested is turned on, and the battery device is charged through the power supply device.

[0036] In actual application, the functional module is turned off, such as ending the playing of audio and video, and then the power supply switch of the device to be tested is turned on, so that the power supply device and the battery device are connected, and then the battery device is charged through the power supply device.

[0037] Further, in the battery testing method of the present invention, in step S4, recording the charging end time after the battery device is fully charged includes: The power of the battery device is monitored, and the charging end time is recorded after the power of the battery device reaches a fully charged state.

[0038] In actual applications, the power level of the battery device is monitored by the control module. After the battery device reaches a fully charged state (power level is 100%), the charging end time is recorded, and an LCD or indicator light is displayed through the prompt module to prompt that the test is completed.

[0039] Further, in the battery testing method of the present invention, in step S3, based on the discharge start time, the discharge end time, the charge start time and the charge end time, the test result of the device to be tested is determined, including: Determine an actual charging time of the device to be tested, where the actual charging time is the difference between the charging end time and the charging start time; Determine an actual discharge time of the device to be tested, where the actual discharge time is the difference between a discharge end time and a discharge start time; If the actual charging time of the device to be tested is less than or equal to the first preset time, and the actual discharging time is greater than or equal to the second preset time, the test result of the device to be tested is that the test passes; If the actual charging time of the device to be tested is greater than the first preset time, and / or the actual discharging time is less than the second preset time, the test result of the device to be tested is that the test fails.

[0040] The actual charging time is equal to the charging end time minus the charging start time. The actual discharging time is equal to the discharging end time minus the discharging start time.

[0041] In actual applications, the device to be tested can be connected to a data processing device (such as a PC tool), and the qualified standard is preset in the data processing device. For example, the qualified standard for charging time is x minutes (i.e., the first preset time), and the qualified standard for discharging time is y minutes (i.e., the second preset time). If the device to be tested simultaneously satisfies: the actual charging time ≤ x minutes, and the actual discharging time ≥ y minutes, it is considered that the test satisfies the pre-set qualified standard, and the test result of the device to be tested can be determined as a passed test. If the device to be tested simultaneously satisfies: the actual charging time > x minutes, and / or the actual discharging time < y minutes, it is considered that the test does not meet the pre-set qualified standard, and the test result of the device to be tested can be determined as a failed test.

[0042] From the above description, it can be seen that the test data obtained by the above-mentioned device to be tested during the whole machine testing process includes the discharge start time, the discharge end time, the charge start time and the charge end time. The test results of the device to be tested can be quickly and accurately judged through the above-mentioned test data to determine whether the performance of the whole device to be tested meets the requirements.

[0043] In summary, the battery testing method and testing system provided by the present invention: (1) realize the automatic start of charging and discharging of the device to be tested, and record the corresponding time and other operations, and then use the PC tool to determine whether the whole machine test of the device to be tested meets the standard. The operation is simple, which can effectively simplify the production process. At the same time, the test data is automatically recorded, and the information can be traced. The PC tool can automatically determine whether the test meets the requirements. (2) The worker only needs to set the device to be tested to the charging and discharging test state (that is, the battery is continuously charged and discharged under simulated actual use conditions), and after connecting the power supply device, wait for the whole machine test operation to be completed, remove the device to be tested, connect the PC tool to determine the test results and upload the test results. The operation is simple and improves the test efficiency.

[0044] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
