<P>PROBLEM TO BE SOLVED: To provide a charging method capable of charging, with a first charge voltage value and charging with a second charge voltage value lower than the first charge voltage value, a secondary battery by using a common battery charger. <P>SOLUTION: The charging method for charging the secondary battery capable of being charged with the first charge voltage value having the same voltage as a prescribed output voltage value of the battery charger, performs a constant current charge and constant voltage charge with the prescribed output current value and output voltage value of the battery charger in the case of charging the secondary battery to the first charge voltage value, and performs the constant current charge with a prescribed output current value C of the battery charger in the case of charging the secondary battery to a second charge voltage value D, and when a battery voltage reaches the second charge voltage value D, performs a low constant current charge with a current value F smaller than that of the constant current charge by switching from the constant current charge to the low constant current charge. <P>COPYRIGHT: (C)2012,JPO&INPIT |
