Abstract

A method for battery charge scheduling for an electric vehicle including a position confirming step for confirming a position of the vehicle, a candidate station obtaining step for obtaining information on position of the candidate battery charge station, a waiting time and a battery charge cost, a candidate battery charge station displaying step for displaying the information of the candidate battery charge stations, a candidate battery charge station selecting step for selecting a candidate battery charge station at which a battery charge is desired to be carried out and a battery charge reserving step for reserving the battery charge at the candidate battery charge station through the station control network based on a setting at the candidate battery charge station selecting step through the in-vehicle information device. By this method, user convenience is improved and actual risks and mental anxieties derived from low battery charge can be relieved or removed.

Claims

1. A method for battery charge scheduling for an electric vehicle by using a station control network formed by a plurality of station control devices which control a battery charge facility equipped in a battery charge station to mutually exchange information among the plurality of station control devices which is cooperatively associated with one another and an in-vehicle information device equipped in the electric vehicle for information exchange with the station control network, the method comprising the steps of

a position confirming step for confirming a current position of the electric vehicle by the in-vehicle information device;

a candidate battery charge station obtaining step for listing up candidate battery charge stations based on the current position of the electric vehicle and obtaining information including position of the candidate battery charge station and information including a waiting time and a battery charge cost of a candidate battery charge facility located in a corresponding candidate battery charge station from the station control network into the in-vehicle information device;

a candidate battery charge station displaying step for displaying the information of the candidate battery charge stations and the information of the candidate battery charge facilities by the in-vehicle information device;

a candidate battery charge station selecting step for selecting a candidate battery charge station at which a battery charge is desired to be carried out and setting a selected candidate battery charge station in the in-vehicle information device; and

a battery charge reserving step for reserving the battery charge at the candidate battery charge station through the station control network based on a setting at the candidate battery charge station selecting step through the in-vehicle information device.

2. The method for battery charge scheduling for an electric vehicle according to claim 1, wherein a vehicle condition confirming step is further included before the position confirming step or thereafter for confirming at least one of items of an in-vehicle battery charge condition, an estimate possible travel distance, an average vehicle speed, a travelling direction, a recommended travel route and a destination of the electric vehicle, whereby at the candidate battery charge station obtaining step, the listed number of candidate battery charge stations is lessened referring to the at least one of the items.

3. The method for battery charge scheduling for an electric according to claim 1, wherein a reservation confirming step is further included after the battery charge reserving step, wherein the reservation confirming step obtains reservation confirmation information which indicates whether the station control network has accepted a reservation at the battery charge reserving step or not from the station control network into the in-vehicle information device and displays the reservation confirmation information on the in-vehicle information device.

4. The method for battery charge scheduling for an electric according to claim 1, wherein a history accumulating step is further included for accumulating a battery charge history information which includes at least one of items of a position of a battery charge carried out station, a near-by facility of the battery charge carried out station and a battery charge condition of the in-vehicle battery at the time of carrying out the battery charge, and the battery charge history information is referred to in at least one of the candidate battery charge stations obtaining step, the battery charge stations displaying step and the candidate battery charge station selecting step.

5. The method for battery charge scheduling for an electric according to claim 1, wherein a history disclosing step is included for disclosing the battery charge history information on the battery charge at the time of carrying out thereof.

6. A device for battery charge scheduling for an electric vehicle by using a station control network formed by a plurality of station control devices which control a battery charge facility equipped in a battery charge station to mutually exchange information among the plurality of station control devices which is cooperatively associated with one another and an in-vehicle information device equipped in the electric vehicle for information exchange with the station control network, comprising:

a position confirming device for confirming a current position of the electric vehicle by the in-vehicle information device;

a candidate battery charge station obtaining device for listing up candidate battery charge stations based on the current position of the electric vehicle and obtaining information including position of the candidate battery charge station and information including a waiting time and a battery charge cost of a candidate battery charge facility located in a corresponding candidate battery charge station from the station control network into the in-vehicle information device;

a candidate battery charge station displaying device for displaying the information of the candidate battery charge stations and the information of the candidate battery charge facilities by the in-vehicle information device;

a candidate battery charge station selecting device for selecting a candidate battery charge station at which a battery charge is desired to be carried out and setting a selected candidate battery charge station in the in-vehicle information device; and

a battery charge reserving device for reserving the battery charge at the candidate battery charge station through the station control network based on a setting by the candidate battery charge station selecting device through the in-vehicle information device.

7. The device for battery charge scheduling for an electric vehicle according to claim 6, wherein the information exchange between the station control network and the in-vehicle information device is carried out through a wireless communication and the in-vehicle information device includes an antenna used for the wireless communication, the antenna being housed in a door handle of the vehicle.

8. The device for battery charge scheduling for an electric vehicle according to claim 6, wherein the in-vehicle information device is formed integrally with an in-vehicle navigation device and commonly includes the information on the current position, road information and the near-by facility information including geographic information or obtains the information on the current position, road information and the nearby facility information including geographic information from the navigation device.
