AI Technical Summary
Technical Problem
When traditional battery cells are stacked, explosion-proof valves are relatively prone to causing serious heat spread, endangering life and property safety.
Method used
In the battery cell group, the explosion-proof valves of two adjacent battery cells are staggered along the third direction, and the explosion-proof valves are prevented from facing each other through the design of protective beams and exhaust channels. The emission of high-temperature substances is controlled by exhaust holes and fire extinguishing system.
Benefits of technology
This effectively avoids heat spread caused by the explosion-proof valve, improves the safety and space utilization of the battery pack, reduces weight and cost, and enhances the safety performance of the battery pack.
