Abstract

An apparatus for providing transportation includes an electric vehicle having a battery, an electric motor, a transceiver, and a battery manager. The battery manager includes a controller configured to control flow of charge between said battery and the electric motor at least in part in response to information received by the transceiver.

Claims

1. An apparatus for providing transportation, said apparatus comprising an electric vehicle, said electric vehicle comprising a battery, an electric motor, a transceiver, and a battery manager, said battery manager comprising a controller configured to control flow of charge between said battery and said electric motor at least in part in response to information received by said transceiver from a clearinghouse for communicating with transceivers associated with a plurality of electric vehicles, wherein said controller is configured to receive, via said transceiver, information representative of a charge ration and to control operation of said battery based on a difference between said charge ration and accumulated charge drawn since receiving said information representative of said charge ration, and wherein said electric vehicle is an all-electric vehicle.

2. The apparatus of claim 1, wherein said controller is configured to halt flow of charge between said battery and said electric motor at least in part in response to information received by said transceiver.

3. The apparatus of claim 1, wherein said controller is configured to receive, via said transceiver, information representative of a charge ration and to halt flow of charge from said battery when said charge ration and an accumulated charge drawn since receiving said information representative of said ration are equal.

4. The apparatus of claim 1, wherein said controller is configured to receive, via said transceiver, information representative of a charge ration and to provide a warning when a difference between said charge ration and an accumulated charge drawn since receiving said information representative of said charge ration reaches a pre-selected value.

5. The apparatus of claim 1, wherein said controller is configured to receive instructions, via said transceiver, to immediately exercise control over flow of charge between said battery and said motor.

6. The apparatus of claim 1, further comprising a GPS unit in communication with said controller.

7. The apparatus of claim 6, wherein said controller is configured to exercise control over flow of charge between said battery and said motor based at least in part on information provided by said GPS unit.

8. The apparatus of claim 6, wherein said GPS unit is configured to provide information representing a location of a repletion station for providing an opportunity to cause additional information to be provided to said controller via said transceiver.

9. The apparatus of claim 1, further comprising said clearinghouse for communicating with transceivers associated with a plurality of electric vehicles.

10. The apparatus of claim 9, wherein said clearinghouse is configured to receive information from a plurality of repletion stations, said information being representative of a charge ration.

11. The apparatus of claim 1, wherein said information received by said transceiver comprises information indicative of a maximum elapsed time.

12. The apparatus of claim 1, wherein said information received by said transceiver, comprises information indicative of a maximum elapsed time and information indicative of a maximum allotted charge.

13. The apparatus of claim 12, wherein said controller is configured to track time usage and charge usage and to disable charge flow from said battery in response to detecting that said charge usage has reached a first pre-defined value and that said time usage has reached a second pre-defined value.

14. The apparatus of claim 13, wherein said controller is configured to track time usage and to begin to track charge usage when said time usage has reached a first pre-defined value.

15. The apparatus of claim 14, wherein said controller is configured to disable charge flow from said battery in response to detecting that said charge usage has reached a second pre-defined value.

16. The apparatus of claim 1, wherein said electric vehicle is an electric motorcycle.

17. The apparatus of claim 1, wherein said clearinghouse the clearinghouse is configured to receive information from a plurality of repletion stations, said information being representative of a charge ration.

18. The apparatus of claim 1, wherein said clearinghouse is in communication with a plurality of repletion stations.

19. The apparatus of claim 1, wherein said controller is configured to control flow of charge between said battery and said electric motor at least in part in response to information being received by said transceiver.

20. A method for managing usage of a battery in an electric vehicle, said method comprising receiving, from a remote repletion site, information indicative of a usage ration for said battery;

during operation of said electric vehicle, causing said usage ration to traverse a trajectory through a battery usage space;

detecting that said usage point has reached a designated point in said usage space; and

disabling charge flow from said battery to a motor of said electric vehicle.

21. The method of claim 20, wherein causing said usage ration to traverse a trajectory comprises traversing a path parallel to a time-usage axis followed by traversing a path parallel to a charge-usage axis.

22. The method of claim 20, wherein receiving information indicative of a usage ration for said battery comprises receiving, from said remote repletion site, information indicating that a user has paid for a usage ration.
