1. An electric supply apparatus that supplies electric energy to a vehicle from outside of the vehicle, the apparatus comprising:

  • an electric power output section that serves as a supply source of electric energy;

    a reception section that receives electric energy from the vehicle;

    a first communication section that communicates with the vehicle and acquires unique information from the vehicle, the unique information being stored in the vehicle and uniquely identifying the vehicle;

    a second communication section that communicates with a server configured to check the unique information against stolen-vehicle information and that acquires a checking result from the server; and

    a control section that supplies electric energy from the electric power output section to the vehicle when the unique information does not coincide with any piece of the stolen-vehicle information in the checking result, andwhen the unique information coincides with any one piece of the stolen-vehicle information in the checking result, the control section discharges electric energy accumulated in a storage battery included in the vehicle, from the storage battery, and causes the reception section to receive the electric energy, whereinthe reception section includes;

    a consumption section that receives from the vehicle and consumes electric discharge energy discharged from the storage battery included in the vehicle; and

    an electricity storage section that receives from the vehicle and accumulates the electric discharge energy; and

    the control section causes the electricity storage section included in the reception section to accumulate the electric discharge energy when a state of charge of the electricity storage section included in the reception section is smaller than a threshold; and

    the control section causes the consumption section to consume the electric discharge energy when the state of charge of the electricity storage section included in the reception section is equal to or more than the threshold.
