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 corresponding to a charging cut-off state of charge (SOC) Sn for the nth charging stage, according to the acquired battery temperature and a preset mapping relationship between a charging cut-off SOC S and a charging current value I for different temperature ranges, wherein Sn>Sn−1, 1<n≤N, and N is the total number of charging stages;
• charge the battery with in the jth charging stage, wherein 1≤j≤N:
• acquire a SOC of the battery at the current time during the charging of the battery;
• if the SOC at the current time is less than Sj, continue to charge the battery with
• if the SOC at the current time is not less than Sj and j<N, charge the battery with Ij+1;
• if the SOC at the current time is not less than Sj and j=N, stop charging the battery.
