AI Technical Summary

Technical Problem

When a battery experiences thermal runaway, the support around the explosion-proof valve is prone to melting, causing the explosion-proof valve to become blocked and unable to release pressure in time, thus reducing battery safety.

Method used

A support structure is set in the battery assembly, and an exhaust channel is formed on the bracket with a melting point higher than the thermal runaway temperature of the battery. This ensures that the explosion-proof valve is not blocked by molten material during thermal runaway, and releases internal pressure and gas through the explosion-proof valve.

Benefits of technology

This effectively prevents the explosion-proof valve from being blocked by molten material, promptly releases internal battery pressure and gas, improves battery safety, and reduces the probability of safety accidents such as explosions.

Abstract

This utility model discloses a battery assembly, including a housing structure, a cover plate, and a bracket. The housing structure is used to accommodate battery cells. The cover plate is installed on the open side of the housing structure and has at least one explosion-proof valve. The bracket is disposed between the battery cells and the cover plate, and the bracket has at least one support structure. The projection of the support structure toward the cover plate at least partially overlaps with the position of the explosion-proof valve. The melting point of the support structure is higher than the temperature at which the battery experiences thermal runaway. This utility model can prevent the explosion-proof valve from clogging when the battery experiences thermal runaway, thus improving battery safety. This utility model also discloses a battery.
