The invention discloses a battery charging method and device, electronic equipment and a storage medium. Acquiring charging data of the power battery adopting pulse charging and discharging data of the power battery adopting pulse discharging; determining a safety pulse current of the power battery at the actual environment temperature based on the charging data and the discharging data, wherein the safety pulse current represents a maximum current value which can be borne by the power battery at the actual environment temperature; safe pulse current is applied to the power battery at the actual environment temperature so as to preheat the power battery; and charging the preheated power battery. The maximum safe pulse current capable of being borne under the endurance capacity of the power battery is determined, and the high-frequency safe pulse current is applied to the power battery, so that the battery can generate heat and preheat the power battery, the lithium precipitation phenomenon is avoided while the low-temperature charging time is shortened, and the service life of the power battery is prolonged. The low-temperature charging of the battery in different scenes is facilitated, and the service life of the battery is prolonged.

    本发明公开了一种电池充电方法、装置、电子设备及存储介质。获取动力电池采用脉冲充电的充电数据和采用脉冲放电的放电数据;基于充电数据和放电数据确定动力电池在实际环境温度下的安全脉冲电流,安全脉冲电流表示动力电池在实际环境温度下充电能够承受的最大电流值;在实际环境温度下对动力电池施加安全脉冲电流,以对动力电池预热;对预热后的动力电池充电。本发明确定动力电池的耐受能力下的最大能够承受的安全脉冲电流,向动力电池施加高频率的安全脉冲电流,使电池能自身产热,对动力电池预热,在缩短低温充电的时间的同时,不会产生析锂现象,利于电池在各个不同的场景下实现低温充电,延长电池的使用寿命。
