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.
