CHARGE CONTROL SYSTEM FOR ELECTRIC MOTOR VEHICLE
First Claim
1. A charge control system for charging a battery in an electric motor vehicle, the vehicle traveling by an electric motor is driven by the battery, the charging of the battery performed by an external power source, the system comprising:
- a travel history database accumulatively storing data of actual travel history from a plurality of electric motor vehicles, the data being information of a vehicle type, a travel route, and an estimated power amount for the travel route;
a route information acquisition unit acquiring information of a planned travel route toward a destination specified by a user;
a power consumption estimation unit calculating an estimated power amount of the battery for the travel of the electric motor vehicle along the planned travel route, wherein the power consumption estimation unit determines the estimated power amount based on data in the travel history database from a same-type vehicle as the electric motor vehicle and a same travel route as the planned travel route; and
a charge control unit controlling a charge of the battery based on the estimated power amount.

Abstract
A charge control system for charging a battery in an electric motor vehicle includes a travel history database, a route information acquisition unit, a power consumption estimation unit, and a charge control unit. The travel history database stores data of actual travel history from a plurality of electric motor vehicles. The route information acquisition unit determines a planned travel route toward a destination specified by a user, and the power consumption estimation unit calculates an estimated power amount of the battery for the travel of the electric motor vehicle along the planned travel route. The charge control unit controls a charge of the battery based on the estimated power amount. The estimated power amount is based on data in the travel history database from a same-type vehicle as the electric motor vehicle and a same travel route as the planned travel route.
