The invention discloses a battery pack equalization method, a battery pack equalization device, battery pack equalization equipment and a computer readable storage medium, and relates to the technical field of batteries. If it is judged that rough equalization needs to be carried out according to the maximum monomer open-circuit voltage, the minimum monomer open-circuit voltage, the preset voltage difference threshold value, the monomer residual electric quantity, the preset residual electric quantity threshold value or the preset voltage threshold value in the battery pack; if yes, calculating the fixed equalization discharge time of each battery cell based on the equalization discharge current, the residual electric quantity and the equalization capacity of each battery cell; and carrying out equalization processing on the battery pack based on the fixed equalization discharge time of each battery cell. According to the invention, the battery pack can be continuously balanced when the open-circuit voltage is in a platform area or a high-end area with the relation between the curve residual electric quantity and the open-circuit voltage and the residual accurate time of each single cell is 0.

    一种电池组均衡方法、装置、设备及计算机可读存储介质,涉及电池技术领域,包括当每个单体电芯的剩余精确均衡时间为0且开路电压处于目标剩余电量与开路电压关系曲线的平台区或者高端区时,若根据电池组中的最大单体开路电压、最小单体开路电压、预设的压差阈值、单体剩余电量、预设的剩余电量阈值或预设的电压阈值判定需要进行粗略均衡,则基于各电芯的均衡放电电流、剩余电量以及均衡容量计算各电芯的固定均衡放电时间;基于各电芯的固定均衡放电时间对电池组进行均衡处理。通过本申请,可以实现电池组在开路电压处于曲线剩余电量与开路电压关系的平台区或者高端区且每个单体电芯的剩余精确时间为0时的继续均衡。
