Abstract
The method of calculating remaining battery capacity specifies battery discharge efficiency with discharge rate and/or temperature as parameters, and calculates remaining battery capacity from integrated discharge current based on the specified discharge efficiency. This method of calculation stores discharge efficiency as an nth order function of discharge rate and/or temperature where n is 2 or greater, computes discharge efficiency based on the stored nth order function with discharge rate and/or temperature as parameters, and calculates remaining battery capacity based on the computed discharge efficiency.
