AI Technical Summary

Technical Problem

Conventional battery packs face limitations in effectively cooling heat generated during charging and discharging, and when thermal runaway occurs in one battery module, the high temperature heat can spread to other modules, risking explosion.

Method used

A battery pack design featuring a main partition wall with heat dissipation pins that extend along various directions to quickly dissipate heat, including linear, wave, and diagonal patterns, and a hollow base plate with flow path pipes and auxiliary heat dissipation pins to enhance cooling.

Benefits of technology

The design effectively cools the battery pack during charging and discharging, and in case of thermal runaway, prevents heat transfer to other modules, thereby preventing explosions.
