Abstract

An embodiment of the present application provides a battery charging method, an electronic device, and an electric device. The charging method provided by the present application performs alternate charge and discharge cycles with high and low currents during the fast-charging-cycle process, which can eliminate polarization caused by high-current fast charging with only a slight increase in charging duration, improve interface lithium plating, prevent abnormal battery cell voltage plunging phenomena, and balance regional SOC differences at the interface caused by fast charging. Furthermore, low-current charging can reduce temperature rise differences within the battery cell, reduce regional overcharging and over-discharging phenomena, improve lithium plating, and also enhance the usable life of the battery, solving the problem that the existing charging method cannot improve lithium plating on the negative electrode of lithium batteries while ensuring fast charging performance.
