The invention provides a power battery management method and device, electronic equipment and a vehicle, and the method comprises the steps: obtaining a single limit voltage value of a power battery in a use scene in real time based on the use scene of the power battery; wherein the use scene comprises a charging scene and a discharging scene; determining a real state-of-charge value of the power battery based on the single body limit voltage value; determining whether a preset condition is met or not based on the real charge state value and/or the single body limit voltage value; wherein the preset conditions comprise an anti-overcharge condition and an anti-overdischarge condition; and if yes, starting a control strategy associated with the preset condition to prevent the power battery from being damaged in the use scene. The charging scene and the discharging scene of the power battery are managed and controlled based on the single body limit voltage value and the real charge state value, the overcharging problem and the overdischarging problem are avoided, and the management accuracy is greatly improved.

    本发明提供一种动力电池的管理方法、装置、电子设备及车辆,包括:基于动力电池所处的使用场景,实时获取动力电池在使用场景中的单体极限电压值;其中,使用场景包括充电场景和放电场景;基于单体极限电压值,确定动力电池的真实荷电状态值;基于真实荷电状态值和/或单体极限电压值,确定是否满足预设条件;其中,预设条件包括防过充条件和防过放条件;若满足,则启动与预设条件关联的控制策略,以防止动力电池在使用场景中被损伤。通过基于单体极限电压值和真实荷电状态值对动力电池的充电场景和放电场景进行管控,避免出现过充问题和过放问题,大大提高了管理精准性。
