Abstract
A battery control method and a battery control apparatus are provided. The battery control method includes the following steps. Whether a charging voltage value of a battery is greater than a voltage threshold is determined. When the charging voltage value is greater than the voltage threshold, a battery temperature of the battery is obtained. When the battery temperature is less than a first temperature, a time parameter is accumulated according to a first accumulating rate. When the time parameter reaches a time threshold, the charging voltage value of the battery is reduced.
