The invention discloses a battery dynamic balancing device, a control method thereof and a vehicle. The device comprises a power battery; a motor controller; a motor; the controller is connected with the motor controller, and the controller is configured to control a bridge arm of the motor controller to drive the motor and enable the first battery pack and the second battery pack to alternately charge and discharge in a first preset state so as to realize self-heating of the first battery pack and the second battery pack; and the absolute value of the difference between the capacitance of the first battery pack and the capacitance of the second battery pack is lower than a preset threshold value. The balancing device can realize dynamic balancing of the electric quantity between the first battery pack and the second battery pack in the battery self-heating process when the vehicle is in the driving working condition, so that the performance of the battery is improved, and the service life of the battery is prolonged.
本发明公开了一种电池动态均衡装置及其控制方法和车辆,所述装置包括:动力电池;电机控制器;电机;控制器,控制器与电机控制器连接,控制器被配置为:在第一预设状态下,控制电机控制器的桥臂,以驱动电机,并致第一电池组和第二电池组交替充放电,以实现第一电池组和第二电池组的自加热,且致第一电池组的电容量与第二电池组的电容量的差值绝对值低于预设阈值。本发明的均衡装置能够实现车辆处于驱动工况下,电池自加热过程中的第一电池组和第二电池组间电量的动态均衡,从而提高电池的性能并延长电池寿命。
