Abstract
A method and apparatus for predicting the remaining discharge time of a battery are provided. The method includes measuring a dynamic parameter of the battery, obtaining a discharge current of the battery, measuring a voltage of the battery and obtaining a temperature of the battery. The remaining run time of the battery is predicted as a function of the measured battery dynamic parameter, the discharge current, the measured battery voltage, the battery temperature, a full charge battery dynamic parameter and an estimated capacity of the battery.
