Abstract
A charging control method includes: monitoring a real-time temperature of the battery during charging a battery with a first real-time charging current; reducing the first real-time charging current to a second real-time charging current at a specified current reduction rate, when the real-time temperature of the battery is greater than a first temperature threshold, the second real-time charging current being a real-time charging current corresponding to that the real-time temperature of the battery is less than the first temperature threshold; and charging the battery according to the second real-time charging current. As such, the temperature rise problem during high-current high-power fast charging can be alleviated, and excessive fluctuations due to instantaneous current adjustment can be prevented from affecting the charging rate thereby improving user experience.
