AI Technical Summary

Technical Problem

Existing battery modules are prone to fires under heat propagation conditions, and these fires are difficult to contain, posing serious risks to property and personal safety.

Method used

A battery module structure is designed, including a single cell component, a module housing, a busbar assembly, and a blocking component. The blocking component expands when heated to close the slot, preventing oxygen from flowing in and venting high-temperature gas, thereby preventing the occurrence and spread of fire.

Benefits of technology

It effectively prevents the occurrence and spread of fire inside the battery module by venting high-temperature gas while blocking oxygen flow, ensuring that the fire can be extinguished quickly.
