Abstract
An apparatus and a method reduces charging time of a multi-battery with a plurality of battery units. A charging process and apparatus charges a first battery unit of a multi-battery, keeps checking whether a current charging the first battery unit reaches a prescribed value, selects and charges a selected second battery unit of the multi-battery along with the first battery unit if the preset value is reached, and charges the second battery unit with a limited maximum magnitude current when the first battery unit is completely charged. Dual-charging operations for both first and second battery units conducted in the present charging process can reduce total charging time of the multi-battery.
