AI Technical Summary
Technical Problem
Traditional battery modules cannot cool when the board temperature rises, resulting in thermal overload problems.
Method used
The mounting hole is formed on the circuit board of the battery module, and the expansion hole extending through the hole to allow air circulation, thereby achieving cooling of the circuit board.
Benefits of technology
Through the design of the expansion hole, air can flow through to cool the circuit board, effectively reducing the temperature and avoiding thermal overload.
