1Temperature
If a temperature regulation member is arranged to heat the battery in low-temperature environment, then the battery can operate in normal temperature range, but the heating efficiency is relatively low
Solution Approach 1:
The heating film is arranged on both sides of the thermally conductive plate in the thickness direction, transforming a single-sided heating structure into a dual-sided heating structure. This dimensional change doubles the heating area and allows simultaneous heating of battery cores on both sides, significantly improving heating efficiency while maintaining the battery's normal operating temperature
