Abstract

A rechargeable battery for powering an electric vehicle, the battery comprising at least one removable and replaceable electrically rechargeable cell, wherein the cell is encapsulated within a capsule compatible with transport along a pipeline.

Claims

1. A rechargeable battery for powering an electric vehicle, the battery comprising at least one removable and replaceable electrically rechargeable cell, wherein the cell is encapsulated within a capsule compatible with transport along a pipeline.

2. Battery according to claim 1, wherein the capsule is compatible with pneumatic transport along a pipeline.

3. Battery according to claim 1 further comprising a plurality of electrically rechargeable cells encapsulated within the capsule, wherein the capsule is removable and replaceable with respect to the battery.

4. Battery according to claim 3 further comprising a plurality of electrically interconnected capsules each with a plurality of electrically rechargeable cells in electrical contact encapsulated therein, wherein each capsule is compatible with transport along a pipeline.

5. Battery according to claim 4, wherein the plurality of capsules comprises first and second types of capsules, the first capsule type including an electrical terminal connector configured to cooperate with the electrical terminal connector of another first capsule type to provide a series connection and the second capsule type including an electrical terminal connector configured to cooperate with the electrical terminal connector of another second capsule type to provide a series connection, wherein the electrical terminal connectors of the first and second capsule type are configured to connect the first and second capsules in parallel.

6. Battery according to claim 1, wherein the capsule comprises first and second concentric electrical terminals at either end thereof.

7. A capsule of electrically rechargeable cells suitable for use within a battery according to claim 1, which capsule comprises a receptacle in which the cell or cells are housed, an electrical terminal at each end of the capsule and at least one circumferential collar for facilitating transport, in use, along a pipeline.

8. Capsule according to claim 6, wherein the at least one collar is configured to cooperate with a pipeline through which the capsule is transported, in use, to guide and/or substantially seal therewith.

9. Capsule according to claim 7, wherein the at least one circumferential collar comprises two circumferential collars.

10. Capsule according to claim 7 further comprising a pair of electrical terminals at each end of the capsule.

11. Capsule according to claim 10 further comprising a switching means for selectively switching, in use, the contact between the pair of terminals at one end of the capsule with those at the other end of the capsule.

12. Capsule according to claim 11, wherein the switching means comprises one or more solid state switches.

13. An electrically powered vehicle comprising a rechargeable battery according to claim 1.

14. Vehicle according to claim 13, wherein the battery comprises an array of tubing within which capsules can be located.

15. Vehicle according to claim 13 further comprising at least one displacement pipeline through which capsules can be transported to and from its rechargeable battery or batteries.

16. Vehicle according to claim 15, wherein the displacement pipeline is pneumatically compatible.

17. An electric vehicle service and/or charging station compatible for use with an electrically powered vehicle according to claim 13, in that it comprises a charging receptacle within which capsules can be temporarily stationed for recharging, and pipelines able to couple with said electric vehicle in a manner to receive and transport said capsules.

18. A repository of multiple capsules according to claim 7, adapted for use with an electric vehicle service and/or charging station in that it comprises pipelines in communication with said service and/or charging station and a stock of capsules.

19. A system of apparatus capable of pneumatically withdrawing from an electric vehicle rechargeable battery one or more capsules according to claim 7.

20. A method of charging or recharging at least one rechargeable battery within an electric vehicle, which comprises pneumatically removing from said battery at least one discharged, partly discharged or faulty capsules according to claim 7, and pneumatically replacing it with another like such capsules in a charged and/or otherwise operational state.

21. A method according to claim 19, which involves use of a service and/or charging station.
