Abstract:
1. A method of determining the capacity of a battery, comprising the steps of determining if the battery is in a transition phase; determining the battery capacity based on a transition phase battery capacity model when the battery is in the transition phase, wherein the transition phase occurs upon one of connection of the battery to a power source and disconnection of the battery from a power source, and the behaviour described by the transition phase battery capacity model approaches the behaviour of real transition phase battery capacity so as to minimize the error of the determined battery capacity; wherein the step of determining the battery capacity based on a transition phase battery capacity model comprises the steps of: determining a battery ID of the battery; selecting the transition phase battery capacity model from a plurality of transition phase battery capacity models based on the battery ID, wherein each of the plurality of transition phase battery capacity models corresponds to a predetermined battery ID; determining a battery voltage.
