Abstract

Provided is an energy controlling method, the method including: determining a charging state level of a battery based on information about a battery state and information about a charging station; generating control information corresponding to the charging state level using a predetermined state table; and transmitting the control information to a vehicle control system associated with a mechanical motion of an electric vehicle, a vehicle multimedia system associated with multimedia apparatuses installed within the electric vehicle, and a service management system associated with a service using a mobile communication network, wherein each of the vehicle control system, the vehicle multimedia system, and the service management system controls a power usage of corresponding apparatuses based on the control information.

Claims

1. An energy controlling method, the method comprising:

determining a charging state level of a battery based on information about a battery state and information about a charging station;

generating control information corresponding to the charging state level using a predetermined state table; and

transmitting the control information to a vehicle control system associated with a mechanical motion of an electric vehicle, a vehicle multimedia system associated with multimedia apparatuses installed within the electric vehicle, and a service management system associated with a service using a mobile communication network,

wherein each of the vehicle control system, the vehicle multimedia system, and the service management system controls a power usage of corresponding apparatuses based on the control information.

2. The method of claim 1, further comprising:

receiving information about the charging station; and

receiving information about the battery state from a battery management module.

3. The method of claim 1, wherein, in the predetermined state table, a power usage policy of corresponding apparatuses of each of the vehicle control system, the vehicle multimedia system, and the service management system is defined with respect to each of a plurality of charging state levels.

4. The method of claim 3, wherein, in the predetermined state table, any one of power-on or power-off of corresponding apparatuses of each of the vehicle control system, the vehicle multimedia system, and the service management system is defined with respect to each of the plurality of charging state levels.

5. The method of claim 1, wherein information about the battery state comprises information about a currently available battery amount.

6. The method of claim 1, wherein information about the charging station comprises at least one of a distance between the electric vehicle and the charging station, information regarding whether the charging station is present in a path between a current position of the electric vehicle and a destination, and information about a charging time at the charging station.

7. The method of claim 1, wherein the vehicle control system manages at least one of an air conditioner, a heater, and an engine motor of the electric vehicle.

8. The method of claim 1, wherein the vehicle multimedia system manages at least one of a radio, an audio player, and a video player.

9. The method of claim 1, wherein the service management system manages an apparatus associated with a navigation service or a traffic information service.

10. The method of claim 1, wherein:

each of the vehicle control system, the vehicle multimedia system, and the service management system comprises an energy control module, and

each of the vehicle control system, the vehicle multimedia system, and the service management system individually controls a power usage using the energy control module in response to the control command.

11. The method of claim 1, wherein a setting value associated with a speed of the electric vehicle is controlled based on the charging state level.

12. An electric vehicle, comprising:

a vehicle control system associated with a mechanical motion of the electric vehicle;
