ABSTRACT:
A remaining charge predicting method which improves the precision of predicting the remaining charge of a rechargeable battery. A battery pack has a measuring circuit which monitors a charge current, discharge current, the voltage of the rechargeable battery and the temperature of the battery. The measuring circuit notifies a power management microcomputer, provided in a portable device, of the measured current, voltage and temperature. The power management microcomputer predicts the remaining charge of the battery based on the received measured values. The battery pack does not perform data processing for predicting the remaining charge.
