Abstract
A power supply system includes a switch that electrically connects or disconnects a load corresponding to 100 V and a power conversion device to or from each other, and a switch that electrically connects or disconnects a load corresponding to 200 V and the power conversion device to or from each other. For supplying electric power from a vehicle to a load, a controller turns on or off each of the switches, based on a power supply capability of the vehicle and respective power demands of the loads.
Claims5
A power supply system that supplies AC power from a system power supply to an electrical load of a house, the power supply system comprising:
- a current circuit breaker that receives AC power supplied from the system power supply to the house, and interrupts the AC power when at least one of electric leakage and overcurrent occurs;
- a load circuit breaker that electrically disconnects the current circuit breaker and the electrical load from each other;
- a power conversion device that supplies AC power from a vehicle to the electrical load when the vehicle is connected to the power conversion device;
- a switch that is capable of switching between electrical connection and disconnection between the load circuit breaker and the power conversion device;
- and
- a switching device that turns the switch on or off, wherein
- the electrical load includes:
- a first load that is operated by a first voltage;
- and
- a second load that is operated by a second voltage different from the first voltage,
- the switch includes:
- a first switch capable of switching between electrical connection and disconnection between the first load and the power conversion device;
- and
- a second switch capable of switching between electrical connection and disconnection between the second load and the power conversion device, and
- for supplying electric power from the vehicle to the electrical load, the switching device turns on or off each of the first switch and the second switch, based on a power supply capability of the vehicle, and a power demand of the first load and a power demand of the second load.
