POWER SOURCE SYSTEM

摘要

[Problem] To be able to use unused energy and to output at high efficiency. [Solution] Provided is a power source system provided with a power storage device, a switch for connecting/disconnecting the power storage device to/from the outside, a converter for converting the power outputted from a power generation apparatus to external power, and a control unit for controlling whether the switch is connected or disconnected. The control unit controls the connection or disconnection of the switch such that if the current outputted from the power generation apparatus is low, the control unit disconnects the power storage device from the outside and charges the power storage device with the power outputted from the power generation apparatus, and if, as a result of such charging, the voltage of the power storage device becomes greater than the operating voltage of the converter, the control unit causes the switch to connect the power storage device to the converter such that the stored power is outputted.
