According to the balance control method and device for the power battery pack, the equipment and the storage medium provided by the invention, through a mode of newly adding the single battery cells, the single battery cell with the maximum charge state and the single battery cell with the minimum charge state are determined, and the balance control of the power battery pack is realized according to the discharge state or the charge state of the battery pack. Therefore, the battery cell in the maximum charge state or the minimum charge state at a certain moment does not participate in the charge-discharge process in a short time, a mode of consuming electric energy through a resistor is not needed, the efficiency of the system is improved, the charge-discharge capacity of each battery is improved, the performance of the whole battery system is improved, and the service life of the whole battery system is prolonged.

    本发明提出动力电池包的均衡控制方法、装置、设备及存储介质,通过新增单体电芯的方式,通过确定最大荷电状态的单体电芯和最小荷电状态的单体电芯,根据电池包的放电状态或充电状态,使某一时刻最大荷电状态或者最小荷电状态的电芯短时间不参与充放电过程,而不需要通过电阻消耗电能的方式,提升系统的效率,提高各电池的充放电能力及整个电池系统的性能及使用时长。
