SECONDARY BATTERY CHARGE METHOD AND BATTERY CHARGER
First Claim
1. A secondary battery charge method, comprising the steps of:
- conducting a pulsed charge control adapted to conduct a pulsed charge by repeating a cycle of a charge condition and a pause condition of a secondary battery at predetermined intervals;
detecting a voltage detection adapted to detect the voltage of the secondary battery;
determining a charge termination determination adapted to determine whether to terminate the charge of the secondary battery based on the battery voltage in a pause condition detected by the voltage detection step; and
terminating a charge termination control adapted to terminate the pulsed charge when it has been determined by the charge termination determination step that the charge should be terminated.
