1. An electric power supply system comprising:
a connecting device that connects a secondary battery provided in a vehicle to a building; and a control apparatus that i) identifies the type of the vehicle that is connected to the connecting device, the type of the secondary battery, or the type of electric power that is distinguishable by the charging source of the electric power stored in the secondary battery, ii) determines a preset electric power supply method based on the identification results, and iii) controls a supply of electric power from the secondary battery to the building based on the determined electric power supply method; wherein the control apparatus identifies the type of the secondary battery or the type of the electric power stored in the secondary battery by obtaining information indicative of the type of the secondary battery or the type of electric power stored in the secondary battery from the vehicle connected to the connecting device; and the control apparatus determines the order of priority in which i) electric power charged from a household power supply of the building, of the charging electric power in the secondary battery, and ii) electric power charged from regenerated electric power that is regenerated while the vehicle is running, are to be supplied to the building, and controls the supply of electric power according to that determined order of priority.
