Abstract

In an electric motor vehicle management system according to the present invention, a portable terminal that is owned by a user and is located in an electric motor vehicle transmits vehicle condition information of the electric motor vehicle including position information of the portable terminal that has been detected by a position detector of the portable terminal to a vehicle condition receiver of an energy management system (EMS) installed in a customer. A battery charging-and-discharging plan creating unit of the EMS creates a charging and discharging plan for a battery through the use of the vehicle condition information of the electric motor vehicle. A charging and discharging device performs at least one of charging and discharging of the battery of the electric motor vehicle in accordance with the battery charging-and-discharging plan for the battery.

Claims
