AI Technical Summary
The heat dissipation effect of the existing battery pack heat exchanger is not ideal, which affects the performance and safety of the battery pack under high temperature conditions, especially during fast charging, where the error increases and affects the normal operation of the battery pack.
An extension is provided on the battery pack plate to connect with the heat-conducting layer of the battery pack. Combined with the bending part and the heat-conducting layer, a dual cooling mode of natural heat dissipation and conductive heat dissipation is formed. Heat exchange is carried out through the heat-conducting layer and the cold plate to improve heat dissipation efficiency.
It achieves rapid cooling of the battery pack's heat sink, reduces heat generation under high current conditions, ensures the safety of the battery pack and the stability of the fast charging function, and improves the accuracy of voltage and temperature acquisition.
