摘要 |
Power is supplied to electronic equipment from a battery pack unit by the control of the battery pack unit. A plurality of battery packs are attached to a personal computer. The battery packs each compare the voltage of the personal computer with the voltage of a battery built in its own battery pack. Upon comparison, charging FETs and discharging FETs provided for the battery packs are independently switched on or off. Accordingly, the battery packs simultaneously supply power to the personal computer.
