Abstract
A power supply system includes: a vehicle; a power cable; and a distribution board configured to be capable of exchanging electric power with an electric power system and the power cable. The distribution board includes: an operation unit operated by a user to select one of a first mode in which the electric power system and the vehicle are interconnected with each other and a second mode in which the electric power system is disconnected from the vehicle and electric power is exchanged between the vehicle and a house; and a switching circuit that switches a source of supply for a receptacle, to which an electrical load is connected, between the electric power system and the power cable and switches the communication line, in accordance with the operation on the operation unit.
Claims4
A power supply system comprising:
- a vehicle including a power storage device and configured to be capable of outputting electric power of said power storage device to outside said vehicle via a power cable connection port;
- a charging/discharging connector configured to be connectable to said power cable connection port;
- a power cable having one end connected to said charging/discharging connector and including a power line and a communication line via which a signal for use in control of charging/discharging is transmitted to said vehicle;
- and
- a distribution board provided in a house and configured to be capable of exchanging electric power with an electric power system and said power cable,
- said distribution board including:
- an operation unit operated by a user to select one of a first mode in which the electric power system and said vehicle are interconnected with each other and a second mode in which said electric power system is disconnected from said vehicle and electric power is exchanged between said vehicle and said house;
- and
- a switching circuit that switches a source of supply for a receptacle, to which an electrical load is connected, between said electric power system and said power cable and switches said communication line, in accordance with the operation on said operation unit, said switching circuit including:
- a first switch that disconnects said power cable and said electric power system from each other and connects said power cable and said receptacle to each other when said second mode is selected,
- a second switch that disconnects said receptacle and said electric power system from each other when said second mode is selected, and
- a signal selector switch that switches said signal from a normal signal to an emergency power supply signal.
A power receiving facility that exchanges electric power with a vehicle including a power storage device and configured to be capable of outputting electric power of said power storage device to outside said vehicle via a power cable connection port, comprising:
- a charging/discharging connector configured to be connectable to said power cable connection port;
- a power cable having one end connected to said charging/discharging connector and including a power line and a communication line via which a signal for use in control of charging/discharging is transmitted to said vehicle;
- and
- a distribution board provided in a house and configured to be capable of exchanging electric power with an electric power system and said power cable,
- said distribution board including:
- an operation unit operated by a user to select one of a first mode in which the electric power system and said vehicle are interconnected with each other and a second mode in which said electric power system is disconnected from said vehicle and electric power is exchanged between said vehicle and said house;
- and
- a switching circuit that switches a source of supply for a receptacle, to which an electrical load is connected, between said electric power system and said power cable and switches said communication line, in accordance with the operation on said operation unit, said switching circuit including:
- a first switch that disconnects said power cable and said electric power system from each other and connects said power cable and said receptacle to each other when said second mode is selected,
- a second switch that disconnects said receptacle and said electric power system from each other when said second mode is selected, and
- a signal selector switch that switches said signal from a normal signal to an emergency power supply signal.
