Abstract
A charging control method and a charging control apparatus are provided. The charging control method may be used to control a charging process of a secondary battery in a terminal device. According to the used charging control method, in the charging process, a battery voltage of the secondary battery may reach a voltage value greater than a limited charge voltage, so that a charging speed of the secondary battery may increase. In addition, in this method, overvoltage of the secondary battery is prevented by gradually reducing a current value of a charging current.
