The embodiment of the invention discloses a battery equalization control method and device, and belongs to the technical field of battery pack equalization. The method comprises the following steps: acquiring a single voltage of any single battery in the battery pack at the current moment and a reference voltage related to the highest single voltage in the battery pack, and controlling the single battery to charge according to the single voltage and the reference voltage, so that the battery pack achieves battery equalization. According to the embodiment of the invention, the single voltage of the single batteries in the battery pack tends to be consistent with the highest single voltage, and the condition that the residual electric quantity among the single batteries is unbalanced is reduced, so that the residual electric quantity among the single batteries is balanced, the battery pack is balanced, and the service life of the battery pack is prolonged.

    本申请实施例公开了一种电池均衡的控制方法和装置,属于电池组均衡技术领域。该方法包括:获取当前时刻的电池组中的任一单体电池的单体电压以及与电池组中的最高单体电压相关的参考电压,根据单体电压和参考电压,控制单体电池进行充电,以使电池组达到电池均衡。本申请实施例使电池组中的单体电池的单体电压与最高单体电压趋于一致,减少了各单体电池之间的剩余电量不均衡的情况,从而实现了单体电池之间的剩余电量均衡,使得电池组达到电池均衡,进而延长了电池组的使用寿命。
