Charging control method, charging control device, electronic device, and storage medium

A charging control device, comprising:

• an obtaining module, configured to obtain fastest-charge data of a battery, wherein the fastest-charge data comprises a plurality of state-of-charge (SOC) increment sections, a charging time corresponding to each SOC increment section, and a maximum battery temperature corresponding to each SOC increment section wherein the charging time corresponding to each SOC increment section in the fastest-charge data is less than or equal to a minimum charging time for the same SOC increment section in historical charging processes;
• and
• a control module, configured to perform charging control on the battery based on the fastest-charge data;
• wherein in performing charging control on the battery based on the fastest-charge data, the control module is configured to:
• obtain a real-time SOC value and a real-time temperature of the battery;
• determine a SOC increment section within which the real-time SOC value falls;
• obtain, from the fastest-charge data, a maximum battery temperature corresponding to the determined SOC increment section;
• perform control to execute a corresponding thermal management policy of the battery based on the real-time battery temperature and the obtained maximum battery temperature;
• determine, after a current charging process ends, whether charging data in the current charging process satisfies a preset fast-charge condition;
• and
• update the fastest-charge data based on the charging data in the current charging process when the charging data in the current charging process satisfies the preset fast-charge condition.
