AI Technical Summary

⚠Technical Problem

Individual cells that experience thermal runaway may spray high-temperature jets into the battery pack, affecting the normal operation of other cells and causing battery pack safety issues.

⚗Method used

A first protective component is set between the battery cells, including a first heat insulation part and a second heat insulation part. The clamping part clamps the sealing part of the battery cell, and the exhaust path is blocked by the clamping part to optimize the exhaust design. Fireproof parts and buffer parts are used to isolate high-temperature smoke and reduce the risk of heat transfer and chain reaction.

🎯Benefits of technology

It effectively blocks high-temperature ejections from thermally runaway cells, optimizes the exhaust path, reduces heat transfer, reduces the risk of chain reactions from thermal runaway, and improves the safety and stability of the battery pack.

Abstract

This utility model relates to the field of soft-pack battery technology, and discloses a battery module and battery pack. The battery module includes a cell unit, a first protective component, and a clamping component. A plurality of cell units are arranged along a first direction to form a battery pack. The main body of each cell unit extends to both opposite ends along a third direction to form sealing portions, and a tab extends from one of the sealing portions. A second heat-insulating portion is connected to the first heat-insulating portion to form the first protective component. The first heat-insulating portion is attached to two main body portions on opposite sides along the first direction, and the second heat-insulating portion is attached to two sealing portions of two adjacent cell units located away from the tab on opposite sides along the first direction. The clamping component clamps the sealing portion near the tab. This utility model provides protection for adjacent cell units through the first protective component, blocking high-temperature ejected materials; and the clamping component blocks the exhaust path at one end of the battery pack, optimizing the exhaust path.
