METHOD FOR CONTROLLING QUICK CHARGER

摘要

PROBLEM TO BE SOLVED: To provide a method for controlling a quick charger which can charge a secondary battery in a short time without requiring a charger body to be enlarged. SOLUTION: A battery voltage Vb during charging is detected and a charging current Ib is varied depending on the value of the battery voltage Vb (as the battery voltage Vb increases during charging, the charging current Ib is switched and lowered in steps). Since the charging current Ib is varied depending on the value of the battery voltage Vb during charging, a rise in surface temperature of a charger body can be kept low and charging of a secondary battery can be achieved in a short time without requiring the charger body to be enlarged.
