Abstract
A method for estimating a capacity of a battery includes providing a look-up table storing data relating to a voltage and a capacity of the battery, and initializing the battery to reach an initialization state which serves as a starting point for a discharging process. The method also includes discharging the battery, from the initialization state, by a first amount of charge to reach a first state, calculating an actual capacity of the battery based on a measured amount of charge discharged from the initialization state to the first state, measuring an open-circuit voltage at the first state, obtaining a look-up capacity of the battery from the look-up table according to the open-circuit voltage measured at the first state, calculating a difference between the actual capacity and the look-up capacity, and correcting the look-up table based on the difference.
