The invention provides a battery cell balancing method and device, electronic equipment and a computer readable storage medium, and the method comprises the steps: collecting a first voltage of each single battery cell in a power battery when the power battery is in the state for each state in target states, sorting the single battery cells according to a sequence of the first voltages from high to low to obtain a first arrangement sequence of each single battery cell in the state; selecting a first preset number of single cells from all the single cells according to the first arrangement sequence of each single cell in the state, and performing primary labeling on the selected single cells by using the first arrangement sequence of each single cell in the state; counting the marking frequency of each single cell, and determining the single cell as a first cell to be balanced when the marking frequency of the single cell is greater than a preset frequency; and carrying out discharge equalization on the first to-be-equalized battery cell. Through the method, the service life and the safety of each battery cell in the power battery are improved.

    本申请提供了一种电芯均衡方法、装置、电子设备及计算机可读存储介质,其中,该方法包括:针对目标状态中的每一种状态,当动力电池处于该状态下时,采集动力电池中每个单体电芯的第一电压,按照第一电压从高到低的顺序对单体电芯进行排序,得到该状态下每个单体电芯的第一排列顺序;根据该状态下每个单体电芯的第一排列顺序,从所有单体电芯中选取出前第一预设数量个单体电芯,使用该状态下每个单体电芯的第一排列顺序,对选取出的单体电芯进行一次标注;统计每个单体电芯的标注次数,当该单体电芯的标注次数大于预设次数时将该单体电芯确定为第一待均衡电芯;对第一待均衡电芯进行放电均衡。通过该方法,提高动力电池中各电芯的寿命和安全性。
