Description

Technical Field

[0001] This utility model relates to the field of optical instrument technology, and in particular to a detachable temperature control fixture and battery testing system. Background Technology

[0002] With the rapid development of photovoltaic technology, new battery technologies such as crystalline silicon cells, perovskite cells, and tandem cells are constantly emerging. Each of these cells has its own performance advantages. To simulate real-life scenarios, everyone is trying to test the cells in different environments to improve their performance. Therefore, there is a need for a product that can simulate different temperature environments, is lightweight and portable, and allows for the replacement of different types of batteries. The fixture is small in size and easy to carry, and has a sealing function to ensure that the battery does not age over a period of time. This fixture integrates control and testing functions.

[0003] The testing equipment in the related technology has the following disadvantages:

[0004] First, the battery is bulky, has low space utilization, and is inconvenient to operate. Commercially available battery testing systems consist of temperature control components and testing components assembled together, each occupying a separate testing space. Furthermore, the testing and temperature control components are fixed in place and cannot be carried around; they cannot be operated simultaneously during testing, which is inconvenient.

[0005] Second: Poor compatibility. The tested product is not compatible with multiple battery types and only supports one type of battery.

[0006] Third: Low integration and incomplete functionality. The test product has low functional integration; functions such as temperature control, testing, and airtight protection cannot be integrated into one unit, failing to fully meet testing requirements.

[0007] Fourth: The temperature control accuracy is not high, and it cannot achieve single-point temperature control or stepped temperature control. The tested product can be temperature controlled, but it cannot achieve the required temperature range and precise temperature accuracy in some harsh testing environments. It cannot achieve continuous single-point temperature control or stepped temperature control, and the temperature sampling accuracy is low.

[0008] Therefore, the relevant technologies need to be improved. Utility Model Content

[0032] Please see Figures 1 to 5 This application provides a detachable temperature control fixture 1, which is suitable for characterizing and testing different types of battery samples (such as monocrystalline silicon batteries, tandem batteries, etc.) in a controlled temperature environment.

[0033] The aforementioned detachable temperature control fixture 1 includes at least a temperature control console body 11, a fixture structure (20, 30), and a temperature control module 21. The components are described below:

[0034] The temperature control platform body 11 can be a one-piece molded structure, with a placement area 12 formed in the center for placing the battery sample 40 to be tested. In addition, the temperature control platform body 11 is provided with a first clamping connection structure 13 and a second clamping connection structure 14, so as to be assembled and disassembled with different clamping structures respectively.

[0035] The clamping structures (20, 30) are detachably mounted on the top area of ​​the temperature control platform body 11 to achieve mechanical clamping and positioning of the battery sample 40 under test.

[0036] The temperature control module 21 can be multiple heating elements (such as ceramic heating plates) or temperature control circuits integrated in the temperature control station body 11 to accurately regulate the temperature of the sample placement area 12 and ensure that the battery operates under the set temperature curve (i.e., to control the ambient temperature of the battery sample 40 under test on the temperature control station body 11).

[0037] To achieve compatible clamping for different types of battery structures, the temperature control console body 11 is provided with a first clamping connection structure 13 and a second clamping connection structure 14, which allows for quick assembly and replacement using different types of clamping components 20 and 30.

[0038] The fixture structure includes a flip-top fixing assembly 30 or a four-sided fixing assembly 20 to accommodate different types of battery samples 40 under test, as detailed below:

[0039] When the type of the battery sample 40 being tested belongs to the first type, that is, when the battery sample 40 being tested is compatible with the flip-type fixing component 30, the flip-type fixing component 40 is assembled on the temperature control platform body 11 as a clamp structure (at this time, the temperature control platform body 11 is used to fix with the flip-type fixing component 30), and the corresponding flip-type fixing component 40 is used to fix and clamp the battery sample 40 being tested.

[0040] When the type of the battery sample 40 being tested belongs to the second type, that is, when the battery sample 40 being tested is compatible with the four-sided fixing component 20, the clamping structure of the four-sided fixing component 20 is assembled on the temperature control platform body 11 (at this time, the temperature control platform body 11 is used to fix with the four-sided fixing component 20), and the corresponding four-sided fixing component 20 is used to fix and clamp the battery sample 40 being tested.

[0041] In practical use, users or operators can select the appropriate fixture structure 20 or 30 according to the type of sample being tested, and quickly install it through the fixture connection structures 13 and 14 on the temperature control station body. After assembly, the sample maintains stable contact in the fixture structure, and the temperature control station body provides a constant controlled temperature. With the help of an external testing system, various performance tests such as photoelectric, current, and voltage can be carried out.

[0042] As can be seen, the detachable temperature control fixture of this application, by adopting a detachable configuration between the clamping structure and the temperature control station body, is compatible with different types of clamping structures (flip-type fixing components or four-sided fixing components), which can meet the fixing requirements of various types of battery samples (such as monocrystalline silicon batteries and stacked batteries), thereby improving the versatility and compatibility of the structure. At the same time, the temperature control module is integrated into the temperature control station body, which can accurately regulate the ambient temperature of the battery sample under test, avoiding the impact of external temperature fluctuations on the test accuracy. The overall device is compact, easy to carry, and has both clamping and temperature control functions, effectively improving test efficiency, adaptability and reliability.

[0043] In optional embodiments of this application, the first type includes monocrystalline silicon and the second type includes stacked silicon.

[0044] When the battery sample 40 being tested is of the single-crystal silicon type, the temperature control station body 11 is used in conjunction with the flip-type fixing component 30; when the battery sample 40 being tested is of the stacked type, the temperature control station body is used in conjunction with the four-sided fixing component 20.

[0045] Specifically, the "first category" includes, but is not limited to, single-crystal silicon type battery samples, such as single-junction solar cells and other devices with regular shapes and standardized dimensions; this type of device has a stable structure and is suitable for quick and reliable clamping using a flip-top fixing assembly. The flip-top fixing assembly can press the device onto the temperature control stage surface through its flip-up structure, making operation convenient and replacement efficient.

[0046] The "second category" includes devices with complex structures, irregular dimensions, and significant thickness variations, such as tandem batteries. For this type of sample, using a four-sided fixing assembly can provide multi-directional clamping force from four directions, more evenly and stably holding the sample, effectively preventing the device from shifting or making poor contact during temperature control.

[0047] It should also be noted that the flip-top fixing component 20 is characterized by requiring only one hand-tightening screw to open / close the clamp, facilitating quick sample replacement and improving operational efficiency. Meanwhile, the four-sided fixing component 30 is secured to the platform using four screws, effectively preventing displacement or warping of large-area components and improving clamping stability and testing consistency.

[0048] Please see Figure 6 The four-sided fixing component 20 is adapted to the battery sample 40 under test that requires multi-sided clamping force, and is especially suitable for devices with relatively complex structures or inconsistent thicknesses, such as stacked batteries.

[0049] The aforementioned four-sided fixing components 20 include at least:

[0050] Multiple sidewall structures 202 are used to limit the four sides of the battery sample 40 under test;

[0051] Multiple screw fixing holes 201 are respectively provided at the top or edge of the side wall structure;

[0052] The side wall structure 202 is used to clamp and limit the four sides of the battery sample 40 under test. The screw fixing holes 201 are used to connect with the corresponding fixing parts (second clamp connection structure 14) of the temperature control platform body 11 through fasteners (screws) to realize the detachable fixed installation of the four-side fixing components 20 and the temperature control platform body 11. That is, during the clamping process, the four-side fixing components 20 form an all-round constraint to prevent the sample from shifting due to thermal expansion and contraction or micro-vibration during heating or testing.

[0053] Please return and continue reading. Figure 3 and Figure 4 The flip-top fixing component 30 is suitable for test battery samples with relatively regular structures and high sample change frequency, such as single-crystal silicon cells.

[0054] The aforementioned flip-type fixing assembly 30 includes at least a flip-type body;

[0055] The flip cover body has a threaded hole 301 on one side and is hinged to the temperature control body 11 via a rotating part 17 on the other side to achieve rotation relative to the temperature control body 11.

[0056] When the flip cover is in the open state ( Figure 4As shown), the operator can directly place the sample into the placement area formed by the temperature control table body; after flipping and closing (i.e., as shown), Figure 3 When in the closed state (as shown), quick clamping is achieved by locking with a single hand-tightened screw (i.e., fixing the flip-top body to the temperature control console body by passing the screw through the threaded hole). The advantage of using the flip-top fixing component 30 in this embodiment is that it facilitates high-frequency experimental switching and reduces operation time.

[0057] Please see Figure 7 The outer shell of the temperature control console 11 is provided with an air inlet 19 and an air outlet 18.

[0058] The air inlet 19 can be a channel opened on the temperature control panel body 11, which is used to draw in air from the external environment. It is usually equipped with a filter structure or grille to prevent dust particles from entering. The drawn-in cold air is guided to the temperature control area through the internal air duct.

[0059] The air outlet 18 can also be a channel opened on the temperature control panel body 11, which is used to discharge the air that has been heated or absorbed by the temperature control module in a timely manner, thereby avoiding the accumulation of heat inside.

[0060] In an optional embodiment of this application, the temperature control module includes a heating unit, a cooling unit, a temperature sensor, and a control circuit.

[0061] Specifically, the heating unit heats the temperature control platform to achieve the required high-temperature testing environment; the cooling unit cools the platform to meet low-temperature testing requirements, satisfying the battery performance testing needs under different ambient temperatures. A temperature sensor collects the current temperature information of the battery sample in real time. The control circuit is electrically connected to the heating unit, cooling unit, and temperature sensor, and controls the heating or cooling unit based on the temperature data fed back from the sensor. This technical solution forms a closed-loop temperature control system, achieving dynamic and precise control of the testing environment temperature to accommodate various temperature-required testing scenarios.

[0062] Please return and continue reading. Figure 1 The temperature control console body 11 is equipped with a temperature control dial device 15 and a fixture temperature control interface 16.

[0063] Specifically, the temperature control dial switch 15, as a dial switch structure with multiple preset control positions, allows users to quickly switch the control strategy of the temperature control module by manually toggling different positions, such as switching between different modes like room temperature maintenance, constant heating, constant cooling, or stepped temperature control. The fixture temperature control interface 16 connects to the temperature acquisition unit set in the fixture structure, transmitting the temperature data detected within the fixture to the control circuit through this interface. This improves the overall system's temperature feedback accuracy and control response speed, thereby ensuring temperature stability and accuracy during the testing process.

[0064] Please return and refer to Figure 2 In an optional embodiment of this application, an electrical testing interface 202 is provided on the outer surface of the four-sided fixing component 20.

[0065] Specifically, the electrical testing interface 202 has a dual-end connection structure. One end is used to establish an electrical connection with the electrode area of ​​the battery sample under test, and the other end is used to establish a signal communication connection with an external electrical testing system. This allows the electrical performance data of the battery sample under a controlled temperature environment to be output to the testing system in real time, thereby achieving the integration and collaboration between the temperature control fixture and the electrical testing equipment, and improving testing efficiency and data acquisition accuracy.

[0066] Please see Figure 8 The detachable temperature control clamp also includes a power control interface 50.

[0067] The power control interface 50 is located on the temperature control unit body 11 and is used to provide power input and switching control signals to the temperature control module. Through this power control interface 50, the power supply and operation start / stop control of the heating unit, cooling unit, and control circuit inside the temperature control unit body can be realized, thereby achieving independent operation of the fixture as a whole and linkage control with external systems. This design improves the operational flexibility and system integration capability of the device.

[0068] This application also provides a battery testing system, including a testing device, a battery, and a detachable temperature control clamp as described in the above embodiments; the detachable temperature control clamp is used to hold the battery, and the testing device is used to test the battery.

[0069] This utility model discloses a detachable temperature control fixture and battery testing system. By detachably configuring the clamping structure and the temperature control platform body, it is compatible with different types of clamping structures (flip-type fixing components or four-sided fixing components), which can meet the fixing requirements of various types of battery samples (such as monocrystalline silicon batteries and stacked batteries), thereby improving the versatility and compatibility of the structure. At the same time, the temperature control module is integrated into the temperature control platform body, which can accurately regulate the ambient temperature of the battery sample under test, avoiding the impact of external temperature fluctuations on the test accuracy. The overall device is compact, easy to carry, and combines clamping and temperature control functions, effectively improving testing efficiency, adaptability and reliability.

[0070] In summary, the detachable temperature control fixture and battery testing system of this application has the following advantages: First, it can realize the testing functions and requirements of most batteries on the market, and there are corresponding detachable fixtures for testing the battery types (such as single-junction battery fixtures and stacked battery fixtures); Second, through the cooperation of the detachable fixture and the temperature control table, it is small in size, has high space utilization, and is easy to carry; Third, it can be adapted to two methods: four-sided fixing fixtures and flip-top fixing fixtures. The flip-top fixing only requires one hand-tightening screw, which makes it easy to replace the fixture, while the four-sided fixing makes it easy to replace the sample.

[0071] The specific embodiments of the utility model have been described in detail above, but they are only examples, and the utility model is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications or substitutions to the utility model are also within the scope of the utility model.
