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 DC charge/discharge port; the controller is connected with the motor controller, and the controller is configured to charge the power battery through the direct-current charging and discharging port and control a bridge arm of the motor controller to enable the first battery pack and the second battery pack to alternately charge and discharge in a first preset state, so that self-heating of the first battery pack and the second battery pack is achieved; 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 equalization device can realize dynamic equalization of the electric quantity between the first battery pack and the second battery pack in the self-heating process when the power battery is charged, 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;直流充放电口;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,通过直流充放电口为动力电池充电,且控制电机控制器的桥臂,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动力电池进行充电时,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。
