Abstract
The present disclosure relates to a battery energy processing device and method and a vehicle. The battery energy processing device includes: a bridge arm converter, having a first bus terminal connected with a positive electrode of a battery and a second bus terminal connected with a negative electrode of the battery; a motor winding, having a first end connected with a midpoint of the bridge arm converter; an energy storage device, respectively connected with a second end of the motor winding and the second bus terminal; and a controller, configured to control, in a first preset state, the bridge arm converter to charge and discharge the battery, so as to realize heating of the battery. In this way, the charging and discharging of the battery can be controlled, and internal resistance of the battery causes the battery to generate a large amount of heat, which causes a temperature rise of the battery, thereby realizing the heating of the battery.
