The embodiment of the invention provides a battery equalization management method, a battery management system and a battery pack. The battery equalization management method is applied to a battery management system, the battery management system is connected to a plurality of series connection nodes in a battery module through a plurality of branches, single batteries are connected between adjacent series connection nodes, each branch is provided with an equalization resistor, and an equalization module is used for realizing equalization of the single batteries by connecting the adjacent branches. The battery equalization management method is used for equalizing battery voltage between adjacent series nodes connected with adjacent branches. The battery equalization management method comprises the following steps: determining an equalization battery set of a battery module; sorting the single batteries in the balanced battery set based on a sequence from large to small; based on a preset number, screening out a preferential equalization battery set from the sorted single batteries, so that branches where the single batteries in the preferential equalization battery set are located are not adjacent; and balancing each single battery in the preferential balancing battery set by controlling the balancing module.
本发明实施例提供了一种电池均衡管理方法、电池管理系统、以及电池包。所述电池均衡管理方法应用于电池管理系统,电池管理系统分别通过多个支路连接到电池模组中的多个串联节点,相邻串联节点之间连接有单体电池,每个支路设置有均衡电阻,均衡模块用于通过连接相邻支路,对相邻支路所连接的相邻串联节点之间的电池电压进行均衡,电池均衡管理方法包括:确定电池模组的均衡电池集合;基于从大到小的次序,对均衡电池集合中的各个单体电池进行排序;基于预设数量,从排序后的各个单体电池中筛选出优先均衡电池集合,使得优先均衡电池集合中的各个单体电池所在的支路不相邻;通过控制均衡模块,对优先均衡电池集合中的各个单体电池执行均衡。
