Description

technical field [0001] The invention belongs to the technical field of batteries, in particular to a battery module. Background technique [0002] An electric vehicle refers to a vehicle powered by an on-board power supply and driven by a motor to drive the wheels. Compared with fuel vehicles, the main difference between pure electric vehicles lies in the four major components, namely the drive motor, speed controller, power battery, and on-board charger. With the development of electric vehicles, higher requirements are placed on the performance of power batteries, especially the low-temperature performance of power batteries. [0003] However, when the ambient temperature is low, the battery does not allow charging, and the discharge energy and power output are drastically reduced. Contents of the invention [0004] The purpose of the present invention is to provide a battery module to improve the working performance of the battery in a low temperature environment. ...
