BATTERY EVALUATION METHOD HAVING CHARGING AND DISCHARGING FUNCTION

摘要

PURPOSE: A battery test method is provided to make it possible that charging and discharging of a battery continuous by controlling charge voltage of a battery. CONSTITUTION: A controlling unit measures(S910) an open circuit voltage. The controlling unit discharges a battery. The controlling unit obtains(S920) information of a current state. The controlling unit charges(S930) a battery. The controlling unit evaluates the current state of a battery based on the information of a state.
