Problems solved by technology

[0011] However, there is no guarantee that electric vehicles will follow a pre-determined travel path
For example, due to power consumption due to errors or traffic jams between routes, or charging and discharging of batteries at the stop, there may be cases where the return is not returned with the battery level estimated in advance.

Abstract

In this electric vehicle management system, a user's mobile terminal (6) in an electric vehicle (5) transmits vehicle state information (S4) about the electric vehicle (5), including position information (S7) of the mobile terminal (6) detected by a position detection unit (61) of the mobile terminal (6), to a vehicle state receiving unit (24) of an energy management system (EMS) (2) installed in a customer's house (1). A battery charge-discharge planning unit (25) of the EMS (2) uses the vehicle state information (S4) about the electric vehicle (5) to determine a charge-discharge plan (S6) for the battery (52). A charge-discharge device (3) then charges and / or discharges the battery (52) of the electric vehicle (5) according to the determined charge-discharge plan (S6).

Description

technical field [0001] The present invention relates to an electric vehicle management system that uses an energy management system (Energy Management System; EMS for short) to control charge and discharge of an electric vehicle battery. Background technique [0002] In recent years, development of a next-generation power grid called a "smart grid" in which an automatic control unit for power supply and demand is incorporated into the power grid has attracted attention. In the smart grid, the flow of power in the power grid is not only controlled from the supply side, but also controlled from the demand side, so as to realize the optimization or balance of power supply and demand. [0003] As an example, the storage battery (battery) of an electric vehicle owned by each household can be used as a buffer for reducing and smoothing the peak value of electric power demand. For example, during a peak power demand period, the peak power demand can be reduced by using the electri...
