Electric power supply system between vehicle and house
First Claim
1. An electric power supply system between a vehicle and a house comprising:
- a power source connecting element configured to have a detachable connection between a vehicular power source disposed at the vehicle and a household power source disposed at the house for an electric power supply in both directions;
a vehicular power state detecting element configured to detect a vehicular power state;
a household power state detecting element configured to detect a household power state; and
a power supply controlling element configured to switch a first state in which electric power is supplied from the vehicular power source to the house and a second state in which electric power is supplied from the household power source to the vehicle, on the basis of the vehicular power state detected by the vehicular power state detecting element and the household power state detected by the household power state detecting element when the vehicular power source disposed at the vehicle and the household power source disposed at the house have been connected by the power source connecting element for the electric power supply in both directions, whereinthe vehicle is a vehicle which drives a driving wheel at least by a motor,the vehicular power source is an electric accumulator, andthe power supply controlling element performs to supply a discharged power from the electric accumulator to the house so as the discharged power from the electric accumulator is consumed on the house side, when a first warm-up operation which increases a temperature of the electric accumulator according to the power discharging of the electric accumulator is detected to be on operation by the vehicular power state detecting element.

Abstract
An electric bower supply system includes a power supply controlling element (62) configured to switch a plug-out power supply which supplies electric power (75) from a fuel cell (20) or a battery (21) to a house (70) and a plug-in power supply which supplies electric power from a commercial power source (75) disposed in the house (70) to a fuel cell vehicle (1a) on the basis of a vehicular power state of the fuel cell (20) and the battery (21) detected by a vehicular power state detecting element (61) and a household power state of the commercial power source (75) detected by a household power state detecting element (81) when a receptacle (10) of the fuel cell vehicle (1a) and an outlet (71) of the commercial power source (75) have been connected by a power cable (100).
