[0002] Module EOL (End of Life) detection refers to the process of performing end-of-life tests on battery modules. Based on module EOL detection, various aspects such as the functions, performance, and compatibility of battery modules can be tested to ensure that the battery modules can still operate normally after maintenance stops, providing guarantee for the safety and reliability of battery modules.

[0003] Currently, the commonly used EOL detection method is dual-station offline synchronous detection, which requires sending the module to the offline detection station for EOL offline detection and then sending the module back to the main production line after the detection is completed, resulting in low detection efficiency.

By arranging the first detection station and the second detection station in sequence along the production line of the module to be tested and respectively completing the online detection of the module to be tested based on the first detection station and the second detection station, the detection efficiency of the module to be tested is improved.

[0037] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a module detection device 01 provided by an embodiment of the present application. Figure 1 Specifically shown is a top view structural diagram of the module detection device 01. The module detection device 01 includes: a first detection station 10 and a second detection station 20 arranged in sequence along the production line of the module to be tested;

[0038] The first detection station 10 is configured to perform one of on-line insulation detection or on-line withstand voltage detection on the module to be tested, and the second detection station 20 is configured to perform the other of on-line insulation detection or on-line withstand voltage detection on the module to be tested.

[0039] Among them, the first detection station 10 can be an insulation detection station for performing on-line insulation detection on the module to be tested; or it can be a withstand voltage detection station for performing on-line withstand voltage detection on the module to be tested. When the first detection station 10 is implemented by an insulation detection station, the second detection station 20 can be implemented by a withstand voltage detection station; when the first detection station 10 is implemented by a withstand voltage detection station, the second detection station 20 can be implemented by an insulation detection station; and then on-line EOL detection of the module to be tested is realized based on the first detection station 10 and the second detection station 20. Specifically, both the first detection station 10 and the second detection station 20 can be implemented by existing EOL detection stations, and one of on-line insulation detection or on-line withstand voltage detection is performed on the module to be tested based on the first detection station 10, and one of on-line insulation detection or on-line withstand voltage detection is performed on the module to be tested based on the second detection station 20.

[0040] It can be seen that the module detection device 01 provided by the embodiment of the present application improves the detection efficiency of the module to be tested by sequentially arranging a first detection station 10 and a second detection station 20 on the production line of the module to be tested, and respectively cooperating with the first detection station 10 and the second detection station 20 to complete the on-line detection of the module to be tested. Without additionally increasing the detection stations, the module detection device 01 uses two detection stations to respectively implement insulation detection and withstand voltage detection in EOL detection, thereby realizing the on-line EOL detection of the module to be tested, saving the time of sending the module to be tested to the off-line detection station and sending the module back to the main production line after the detection is completed, and improving the module detection efficiency. It solves the technical problem of the low detection efficiency of the existing EOL detection method.

[0041] Please refer to Figure 2 , Figure 2 FIG. is a schematic structural diagram of another module detection device 01 provided by the embodiment of the present application. In some alternative embodiments, the first detection station 10 includes a first lifting mechanism 101 and a first detection mechanism 102; the first lifting mechanism 101 is configured to lift the module to be tested to a first target detection position when the module to be tested reaches the first lifting position along the production line; the first detection mechanism 102 is configured to perform the on-line insulation detection on the module to be tested at the first target detection position; the second detection station 20 includes a second lifting mechanism 201 and a second detection mechanism 202; the second lifting mechanism 201 is configured to lift the module to be tested to a second target detection position when the module to be tested reaches the second lifting position along the production line; the second detection mechanism 202 is configured to perform the on-line withstand voltage detection on the module to be tested at the second target detection position.

[0042] The first lifting mechanism 101 can be implemented by a first power unit and a first guide unit. The first power unit provides the first lifting mechanism 101 with power to lift the module under test, while the first guide unit ensures the stability and accuracy of the module under test during the lifting process. The first lifting mechanism 101 can lift the module under test upward, allowing it to separate from the conveyor mechanism and be lifted to the first target inspection position, achieving precise positioning for testing. The first lifting mechanism 101 also provides a stable platform for online insulation testing of the module under test. Specifically, the first lifting mechanism 101 can be positioned at the first lifting position on the production line. It can lift the module under test from the first lifting position to the first target inspection position, whereupon the first inspection mechanism 102 can perform online insulation testing on the module under test. Accordingly, the second lifting mechanism 201 can be implemented by a second power unit and a second guide unit. The second power unit provides the second lifting mechanism 201 with power to lift the module under test, while the second guide unit ensures the stability and accuracy of the module under test during the lifting process. Based on the second lifting mechanism 201, the module to be tested can be lifted upward, so that the module to be tested is separated from the conveying mechanism and lifted to the second target detection position, so as to achieve accurate test positioning of the module to be tested, and based on the second lifting mechanism 201, a stable online voltage resistance testing platform is provided for the module to be tested.

[0043] In some optional embodiments, the second detection mechanism 202 includes a withstand voltage detection unit and a total pressure internal resistance detection unit; the withstand voltage detection unit is configured to perform the online withstand voltage detection on the module to be tested at the second target detection position; the total pressure internal resistance detection unit is configured to perform the total pressure internal resistance detection on the module to be tested at the second target detection position.

[0044] Among them, the withstand voltage detection unit can be specifically implemented by a withstand voltage detection probe board for obtaining withstand voltage detection data, and a withstand voltage detection data processor for analyzing the withstand voltage detection data.

The total pressure internal resistance detection unit can be specifically implemented by a total pressure internal resistance detection probe board for obtaining total pressure internal resistance detection data, and a total pressure internal resistance detection data processor for analyzing the total pressure internal resistance detection data. The total pressure internal resistance detection data processor can analyze the withstand voltage detection data based on the existing total pressure internal resistance detection method, and obtain the total pressure internal resistance detection result of the corresponding module to be tested. Since the time required for insulation detection is usually greater than the time required for withstand voltage detection, by placing the total pressure internal resistance detection and withstand voltage detection on the same workstation, the module EOL detection matters can be increased while ensuring the detection efficiency, so as to further improve the reliability of the EOL detection results.

[0045] In some alternative embodiments, the first detection station 10 further includes a first scanning mechanism; the first scanning mechanism is configured to scan a first information code of the module under test when the module under test is lifted to the first target detection position; the second detection station 20 further includes a second scanning mechanism; the second scanning mechanism is configured to scan a second information code of the module under test when the module under test is lifted to the second target detection position.

[0046] Wherein, the first scanning mechanism or the second scanning mechanism can be implemented by a barcode scanner, a fixed barcode scanner, a radio frequency identifier, etc.; the specific implementation manners of the first scanning mechanism and the second scanning mechanism can be the same or different, and the present application does not make specific limitations thereto. Through the first scanning mechanism and the second scanning mechanism, the module information of the corresponding module under test can be automatically identified to quickly obtain information such as the model, production batch or serial number of the module under test, thereby improving the testing efficiency. Based on the module information, the module detection result can also be matched with the corresponding module to record and track the module detection progress, which is convenient for subsequent quality monitoring and management.

Through the first position detection mechanism 103 and the second position detection mechanism 203, it can be detected whether the module under test reaches the corresponding lifting position; and then when the module under test reaches the corresponding lifting position, the corresponding lifting mechanism is reminded to lift the module under test to the target detection position.

[0049] In some alternative embodiments, the first position detection mechanism 103 includes a first photoelectric sensor; the second position detection mechanism 203 includes a second photoelectric sensor.

The third position detection mechanism 30 can detect whether there are other modules to be tested at the first lifting position or the second lifting position, thereby ensuring that the module to be tested does not enter the same testing station as other modules to be tested, thereby ensuring the orderly testing of multiple modules to be tested.

[0054] The blocking mechanism can be implemented by structural components such as a blocking plate and a blocking cylinder. The blocking mechanism can be connected to the module to be tested. Specifically, the module to be tested can be placed on a transmission plate. The power mechanism drives the transmission plate to move along the production line, thereby driving the module to be tested along the production line. The blocking mechanism can be installed on both sides of the transmission plate. The blocking mechanism blocks the module to be tested at the corresponding lifting position, ensuring that the module to be tested can be lifted by the lifting mechanism to the corresponding target detection position.

[0055] In some optional embodiments, the first lifting mechanism 101 includes a first guide member and a first driving member; the first guide member is configured to limit the moving direction of the module to be tested to a first target guide; the first driving member is configured to drive the module to be tested to rise from the first lifting position to the first target detection position along the first target guide, or to fall from the first target detection position to the first lifting position; the second lifting mechanism 201 includes a second guide member and a second driving member; the second guide member is configured to limit the moving direction of the module to be tested to a second target guide; the second driving member is configured to drive the module to be tested to rise from the second lifting position to the second target detection position along the second target guide, or to fall from the second target detection position to the second lifting position.

The implementation manner of the second guiding member can be the same as or different from that of the first guiding member. The first driving member can be implemented by a motor or a cylinder.
