AI Technical Summary
When a single battery module in a current battery pack fails, the entire battery pack needs to be disassembled to remove the faulty battery module, resulting in low maintenance efficiency and potential damage to other battery modules.
The design incorporates a removable top cover and bottom cover, with each cover corresponding to at least one battery module. The faulty module can be removed by disassembling the cover at the fault location. Combined with independent electrical system control, targeted maintenance and replacement can be achieved.
It improves the maintenance efficiency of the battery pack, avoids damage to normal battery modules, simplifies the wiring structure, and enhances space utilization and structural strength.
