Method, apparatus, and device for charging a battery and storage medium

An apparatus for charging a battery, comprising:

• a processor;
• a memory for storing processor-executable program codes;
• and
• wherein the processor is configured to:
• acquire a battery temperature of the battery;
• determine a charging current value In for the nth charging stage of the battery, according to the acquired battery temperature and a preset mapping relationship between different temperature ranges and charging current values I, wherein 1<n≤N, N is the total number of charging stages, and a preset charging cut-off voltage value Vn for the nth charging stage is greater than Vn−1;
• charge the battery with Ij in the jth charging stage, wherein 1≤j≤N;
• acquire a voltage value of the battery at the current time;
• if the voltage value at the current time is less than Vj, continue to charge the battery with Ij;
• if the voltage value at the current time is not less than Vj and j<N, charge the battery with Ij+1;
• if the voltage value at the current time is not less than Vj and j=N, stop charging the battery.
