Abstract

The present disclosure provides a method, apparatus, and device for charging a battery, and storage medium. The method for charging a battery includes acquiring a battery temperature; determining a charging current value Ifor the ncharging stage of the battery, according to the battery temperature and a mapping relationship between different temperature ranges and charging current values I, wherein a preset charging cut-off voltage value Vfor the ncharging stage is greater than V; charging the battery with Iin the jcharging stage; acquiring a voltage value of the battery at the current time; if the voltage value is less than V, continuing to charge the battery with I; if the voltage value is not less than Vand j<N, charging the battery with I; if the voltage value is not less than Vand j=N, stopping charging the battery.
