Abstract:
PROBLEM TO BE SOLVED: To provide a method of identifying a polarized battery, and then rapidly depolarizing the polarized battery, and to bring the battery in an appropriate state allowing a correct battery test after the depolarization.
SOLUTION: This method of depolarizing a polarized rechargeable battery by charging includes processes of: (a) discharging the polarized battery to cause reduction of at least 0.1 V in an open circuit voltage; (b) detecting the open circuit voltage for determining the speed of change of the open circuit voltage; and (c) repeating the process (a) when the speed of change exceeds 10 mV/30 sec. The method also includes processes of: (a) discharging the polarized battery; (b) detecting the open circuit voltage; and (c) repeating the process (a) when a voltage-to-battery ratio (voltage per one battery) exceeds 2.13 V.
