The embodiment of the invention discloses a power determination method and device of a power battery, electronic equipment and a storage medium, and relates to the technical field of vehicle control. The method comprises the following steps: determining an average charging voltage and an average discharging voltage of a power battery in a preset electric quantity range; determining a battery aging factor according to the charging average voltage and the discharging average voltage; acquiring the initial power of the power battery in the BOL state of the initial life of the battery system and the current battery capacity retention ratio SOH; and determining the current power of the power battery according to the initial power, the current SOH and the battery aging factor. In the technical scheme provided by the embodiment of the invention, the battery power is corrected through the battery aging factor, the current SOH of the power battery is considered when the current power is determined, the current aging degree of the power battery is also considered, the power determination accuracy is improved, meanwhile, abuse of the power battery in the later life period is avoided, and the service life of the power battery is prolonged. Therefore, the service life of the power battery is prolonged.

    本申请实施例公开了一种动力电池的功率确定方法、装置、电子设备及存储介质,涉及车辆控制技术领域。该方法包括:确定动力电池在预设电量范围内的充电平均电压和放电平均电压;根据充电平均电压和放电平均电压,确定电池老化因子;获取动力电池在电池系统生命初期BOL状态的初始功率和当前电池容量保持率SOH;根据初始功率、当前SOH和电池老化因子,确定动力电池的当前功率。本申请实施例提供的技术方案中,通过电池老化因子对电池功率进行修正,在确定当前功率时不仅考虑了动力电池的当前SOH,还考虑了动力电池的当前老化程度,提高了功率的确定准确率,同时避免了在生命后期对动力电池的滥用,从而延长了动力电池的使用寿命。
