The invention relates to a battery self-heating system and a vehicle, and relates to the technical field of electric automobiles, and the battery self-heating system is characterized in that when one of a first battery pack and a second battery pack is in a discharging state, the other one of the first battery pack and the second battery pack is in a charging state; therefore, voltage fluctuations of the first battery pack and the second battery pack counteract each other, terminal voltage fluctuation of the power battery pack is small, and charging failure is avoided.

    本公开涉及一种电池自加热系统及车辆,涉及电动汽车技术领域,包括第一电池组和第二电池组中的与所述第二电池组的其中之一处于放电状态时,所述第一电池组与所述第二电池组的另外之一处于充电状态,这样第一电池组和第二电池组的电压波动相互抵消,使得动力电池包的端电压波动较小,从而避免充电失败。
