Abstract
A pulse charge method for a nonaqueous electrolyte secondary battery, includes: a charge control step of pulse charging by supplying a pulsed current periodically to the nonaqueous electrolyte secondary battery; a battery voltage detection step of measuring a battery voltage of the nonaqueous electrolyte secondary battery; a comparison step of comparing the battery voltage, measured in the battery voltage detection step when the pulsed current is supplied, with a predetermined set voltage; and a charge end control step of ending the pulse charging when a comparison result shows that the measured battery voltage is equal to or higher than the set voltage.
