The embodiment of the invention provides a battery equalization time calculation method and device, equipment and a medium, and the method comprises the steps: obtaining the threshold time when the voltage of each battery cell in a charging process reaches an equalization threshold voltage for a plurality of battery cells in a battery pack, the threshold time of the first battery cell reaching the balance threshold voltage is the reference time; calculating the charging electric quantity of the battery cell in a first time period in the charging process, wherein the first time period is a time period from the reference time to the threshold time of the battery cell; and determining the equalization time of the battery cell according to the charging electric quantity of the battery cell. According to the method, the equalization time required by each battery cell of the battery pack during battery equalization can be accurately calculated.

    本公开实施例提供一种电池均衡时间的计算方法、装置、设备和介质,其中方法包括:对于电池包中的多个电芯,获取每个所述电芯在充电过程中的电压达到均衡门限电压的门限时间,其中,第一个达到所述均衡门限电压的电芯的门限时间为基准时间;计算所述电芯在充电过程中的第一时间段内的充电电量,所述第一时间段为从所述基准时间到所述电芯的门限时间的时间段;根据所述电芯的所述充电电量确定所述电芯的均衡时间。该方法可以精确地计算出电池包各电芯在电池均衡时所需要的均衡时间。
