[0003] Existing monitoring technologies have the following shortcomings:

[0004] Insufficient multi-parameter collaborative monitoring capability: Traditional monitoring equipment mostly uses thermocouples or infrared thermal imagers alone, which makes it difficult to simultaneously acquire temperature field, appearance changes and electrical parameter data, and cannot fully analyze the thermal-electric coupling characteristics during battery charging and discharging.

[0005] Poor visualization accuracy and real-time performance: Conventional CCD cameras have low resolution and cannot capture subtle abnormalities such as overheating of battery tabs and micro-cracks, and there is also a delay in data transmission;

[0006] Insufficient equipment integration and flexibility: The monitoring components are mostly independent devices, requiring manual wiring and debugging. They also need to be disassembled and reassembled when adapting to different battery specifications, resulting in low efficiency.

[0007] Lack of safety protection: There may be risks such as leakage and fire during battery charging and discharging. Existing devices lack protective structures, and the safety of operators cannot be guaranteed.

[0008] Therefore, it is necessary to provide a device for visually monitoring the battery charging and discharging process to solve the above-mentioned technical problems. Utility Model Content
