AI Technical Summary

Technical Problem

Existing battery modules experience reduced charging and discharging performance in low-temperature environments, affecting the battery's usable capacity and safety. Furthermore, the space occupied by the heating module leads to a reduction in battery pack capacity.

Method used

The system employs a combination of heat-conducting components and heating elements. The heat is conducted through the heat-conducting components to heat the individual cells, avoiding direct heating and ensuring that the cells can operate normally in low-temperature environments. It also uses zoned heating control to meet the needs of different individual cells.

Benefits of technology

It enables battery modules to operate normally in low-temperature environments, maintains good compatibility and flexibility, and ensures safety performance and space utilization while reducing production costs.
