The invention discloses an equalization method, device and equipment of a multi-branch battery system and a storage medium, and relates to the technical field of power battery intelligent control, the method comprises the following steps: acquiring SOC range between battery branches in a power battery charging configuration stage, and judging: if the range is not less than a set percentage, adopting a one-by-one confluence charging mode for the battery branches, and if the range is not less than the set percentage, adopting a one-by-one confluence charging mode for the battery branches; quickly charging after all the battery branches are converged, and calculating the electric quantity required to be balanced in the battery cells in the fully-charged battery branches based on a preset algorithm, so as to realize electric quantity balance; if the range is smaller than the set percentage, all the battery branches are controlled to perform fast charging at the same time, and the electric quantity needing to be balanced in the battery cells in the fully-charged battery branches is calculated based on a preset algorithm, so that electric quantity balancing is achieved. According to the invention, the problem of unbalanced electric quantity existing among the branches of the multi-branch parallel battery pack can be effectively solved.

    本发明公开了一种多支路电池系统的均衡方法、装置、设备及存储介质,涉及动力电池智能控制技术领域,该方法包括在动力电池充电配置阶段获取电池支路间的SOC极差,并判断:若极差不小于设定百分比,则对电池支路采用逐一汇流充电方式,并待所有电池支路汇入后进行快充充电,基于预设算法计算满充电池支路中电芯需均衡的电量,实现电量均衡;若极差小于设定百分比,则控制所有电池支路同时进行快充充电,基于预设算法计算满充电池支路中电芯需均衡的电量,实现电量均衡。本申请能够有效解决多支路并联电池组支路间存在的电量不均衡问题。
