Abstract
A power supply includes fuel cell, secondary battery, power converter, current detecting unit and control unit. The power converter couples the fuel cell with the secondary battery, and is adapted to convert current outputted by the fuel cell into output current. The current detecting unit couples the power converter with the secondary battery and adapted to detect charging current of the output current transferred to the secondary battery. The control unit couples the current detecting unit with the power converter and is adapted to: when the charging current is greater than a charging current upper-limit-setting value of the secondary battery, a down-adjustment signal is outputted to the power converter to reduce the output current; and when the charging current is less than the charging current upper-limit-setting value, an up-adjustment signal is outputted to the power converter to increase the output current.
