Abstract

An energy power depositing/charging management system and method is provided. When energy is deposited in an energy storage station from an onboard power storage device of a vehicle, a vehicle energy management unit manages reductions in the remaining stored energy level of energy in the onboard power storage device. The vehicle energy management unit and a storage station energy management unit manage increases in the energy remaining amount of deposited energy in the energy storage station, thereby allowing for charging up to the remaining amount of deposited energy of energy identified with an ID for the vehicle in the energy storage station.
