The invention provides a composite equalization method for equalization processing of a battery pack, which obtains a voltage difference by using a state of charge, realizes that equalization is started and stopped as long as a target threshold value is reached in a full-time period and an area without a voltage platform, and provides an equalization time estimation method. The purpose of accurately predicting the balanced switching process is achieved. 本发明提供一种用于电池组的均衡处理的复合均衡方法，其利用荷电状态来获得电压差，实现了在全时段，无视电压平台区，只要达到目标阈值就开启均衡以及关闭均衡，并且给出均衡时间预估方法，达到能够准确预测均衡的开关的过程的目的。
