Claim 6:
7. A power feeding system comprising:
a storage battery configured to be rechargeable and dischargeable, and to output power at a storage battery output voltage;
a charge/discharge control circuit configured to control charging/discharging power to/from the storage battery;
a power source at least having a power supply capability, wherein the power source includes a generator;
a power conversion circuit configured to convert DC power supplied from the storage battery and the power source into AC power and output the AC power to a power supply destination; and
a control unit configured to control an operation of the charge/discharge control circuit, wherein
in a case where a magnitude of supply destination power which is consumption power at the power supply destination to be supplied with power by the power source is lower than an upper limit value of the power supply capability of the power source, the power supply destination being a house or a power grid line, the control unit controls the charge/discharge control circuit so as to meet the supply destination power of the house or the power grid line based on power output from the power source and to charge the storage battery with power which is a difference obtained by subtracting the supply destination power from the upper limit value of the power supply capability of the power source,
in a case where the magnitude of the supply destination power of the house or the power grid line is more than or equal to the upper limit value of the power supply capability of the power source, the control unit controls the charge/discharge control circuit so as to meet the supply destination power of the house or the power grid line by both the power source and the storage battery, and
in a case where the power source is disconnected from the power feeding system for replenishing the power source with fuel, the control unit controls the charge/discharge control circuitry so as to continue a maximum power supply to the power supply destination when the power source is disconnected from the power feeding system, and the control unit controls the charge/discharge control circuitry responsive to a forced charging instruction from a user so as to force charging of the storage battery prior to disconnecting the power source from the power feeding system for replenishing the power source with fuel.
