Abstract
A method of battery capacity measurement is actualized by battery internal resistance. This method establishes a controlled discharge path inside the battery module. The battery discharge current is a constant value despite of the variation of system loading current. The internal resistance measured by establishing this constant battery current can be used to obtain the battery capacity precisely.
