ELECTRIC-POWER SUPPLY SYSTEM, AND VEHICLE

摘要

A first hybrid vehicle (10A) is connected to a house-side connector (40). A second hybrid vehicle (10B) is connected to the first hybrid vehicle (10A), and they are connected in parallel within the first hybrid vehicle (10A) with respect to a house load (20). When a commercial system power source (50) is interrupted, an automatic switching circuit (30) is activated, and the house load (20) receives electric power from the first and second hybrid vehicles (10A, 10B). The first hybrid vehicle (10A) determines allocations of the amounts of electric power supply from the first and second hybrid vehicles (10A, 10B) based on the amount of the house load (20) and on the residual amounts of fuel in the first and second hybrid vehicles (10A, 10B).
