The invention provides a power battery equalizing charging method and device, electronic equipment and a vehicle, and the method comprises the steps: monitoring a voltage value of each battery cell in response to an equalizing charging starting signal; stopping charging the power battery when the voltage value of the highest voltage battery cell of the current round reaches the corresponding battery cell cut-off value and the battery charging current is smaller than or equal to the charging cut-off current; taking the highest voltage cell of the round as an anti-overcharge cell, controlling the anti-overcharge cell to discharge, and obtaining the discharge capacity of the anti-overcharge cell; and charging the power battery, monitoring the voltage value of each cell and the charging amount of the anti-overcharge cell, and if the voltage value of the highest voltage cell in the current round reaches the corresponding cell cut-off value or the charging amount of the anti-overcharge cell reaches the discharge amount, stopping charging the power battery. According to the scheme, the voltage value and the charging amount of each battery cell can be considered at the same time during equalizing charge control, and each battery cell is prevented from being overcharged while equalizing charge of each battery cell of the power battery is ensured.

    本申请提供一种动力电池均衡充电方法、装置、电子设备和车辆,包括:响应于均衡充电启动信号,监测每一电芯的电压值;本轮次最高电压电芯的电压值达到其对应的电芯截止值且电池充电电流小于或等于充电截止电流,停止为动力电池充电;以本轮次最高电压电芯作为防过充电芯,控制防过充电芯放电并获取防过充电芯的放电量;为动力电池充电,监测每一电芯的电压值以及防过充电芯的充电量,若当前轮次最高电压电芯的电压值达到其对应的电芯截止值或防过充电芯的充电量达到放电量,则停止为动力电池充电。本方案能够在均衡充电控制时,同时考虑每一电芯的电压值和充电量,在确保动力电池的各个电芯均衡充电的同时,防止各个电芯出现过充。
