Abstract

An apparatus for providing a secondary power source for an electric vehicle and having at least one secondary electrical power storage unit for storing electrical energy for delivery to the electric vehicle as required to replace the primary power source, a power connection assembly to connect the at least one secondary power source to the electric vehicle and a control system to control supply to the electric vehicle.

Claims

1. A system for providing a secondary power source for an electric vehicle having a primary power source, the system comprising an apparatus attachable to the electric vehicle and having at least one secondary electrical power storage unit including a battery for storing electrical energy for delivery to the electric vehicle as required to replace the primary power source, and at least one proprietary plug associated with the apparatus, a power connection assembly to connect the apparatus to the electric vehicle, and a battery control system embedded in each storage unit and adapted to control supply to the electric vehicle, and an authorisation system to authorize delivery of the electrical energy from the storage unit, at least one communication pathway associated with the apparatus, wherein the control system undertakes an authorisation process utilising the authorisation system remotely through the at least one communication pathway before electrical energy is delivered from the storage unit, wherein the control system identities each storage unit and each proprietary plug to charge/connect each storage unit within the system in order to track the use of each storage unit for access, restricting or denial of access and billing, the apparatus being configured as a modified wheeled platform or the battery attached to the vehicle and wherein the system controls the input of power or energy into the battery and prevents unauthorized charging of the battery.

2. The system as claimed in claim 1 wherein the vehicle is a car or truck.

3. The system as claimed in claim 1 wherein the secondary power source includes a location receiver and a wireless communication device to allow the location of the secondary power source to be identified, substantially in real-time.

4. The system as claimed in claim 1 wherein the apparatus is configured as a towable trailer to be towed by the electric vehicle.

5. The system as claimed in claim 4 wherein the apparatus includes a breaker or spacer assembly at a forward end of the trailer defining a volume extending across a forward end of the trailer in order to provide a buffer space in case of accidents or similar.

6. The system as claimed in claim 4 wherein the trailer is length adjustable, provided in a pair of portions, namely a front portion and a rear portion which slide relative to one another.

7. The system as claimed in claim 4 wherein the trailer includes a forward wall assembly provided with a draw assembly in order to attach the trailer to the electric vehicle and the electric vehicle is provided with a corresponding assembly to attach.

8. The system as claimed in claim 1 wherein the apparatus is configured as a self-propelled, wheeled platform a removably mounted relative to a larger vehicle and to be off the ground when mounted to the larger vehicle.

9. The system as claimed in claim 1 further including at least one mounting assembly to mount the apparatus relative to the electric vehicle and to allow the electric vehicle to operate using electrical energy stored in the at least one secondary electrical power storage unit or an electric vehicle primary electrical power storage unit.

10. The system as claimed in claim 1 wherein the control system allows selection of the at least one secondary electrical power storage unit or the electric vehicle primary electrical power storage unit.

11. The system as claimed in any one of the preceding claims 1 to 10 wherein the apparatus includes a number of swappable battery systems which can attach to and/or fit into enclosed or open compartments on vehicles.

12. The system as claimed in claim 1 wherein the apparatus is configured as a self-propelled, wheeled platform for delivery of the at least one secondary electrical power storage unit to the electric vehicle.

13. The system as claimed in claim 1 wherein the apparatus has an internal unit in order to bold or contain the secondary power source.

14. The system as claimed in claim 13 wherein the internal unit is removable and replaceable from the apparatus.

15. The system as claimed in claim 13 wherein the secondary power source is removable and replaceable from the internal unit.

16. The system as claimed in claim 13 wherein the internal unit has a number of subunits and wherein each subunit contains one or more batteries.

17. The system of claim 1 wherein the secondary power source includes one or more batteries and the one or more batteries are removable and/or loadable into the vehicle.

18. The system as claimed in claim 1 wherein the at least one secondary electrical power storage unit comprises one or more batteries and wherein the electric vehicle draws electrical energy from the one or more batteries whilst the apparatus is mounted relative to the vehicle.

19. The system as claimed in claim 1 wherein the secondary power is connected in a grid within the apparatus and then the grid is connected to the electric vehicle.

20. The system of claim 1 wherein the control system is provided in or on the apparatus or in the electric vehicle or partially in both.

21. The system as claimed in claim 1 wherein the control system allows monitoring of the status of the secondary power source.

22. The system as claimed in claim 1 wherein a wireless connection is provided to a vehicle display to convey information about status and operation of the secondary power source to a driver of the electric vehicle.

23. The system as claimed in claim 1 wherein the apparatus is configured as a wheeled apparatus for transport and/or delivery of the at least one secondary electrical power storage unit to the electric vehicle.

24. The system as claimed in claim 1 wherein the apparatus includes one or more deployable wheel assemblies for at least temporary support of the apparatus either in conjunction with a rear support wheel assembly or for temporary support in the absence of a rear support wheel assembly.

25. The system of claim 1 wherein the apparatus is configured as an unwheeled unit which has an associated mobile delivery vehicle for delivery of the at least one secondary electrical power storage unit to the electric vehicle.

26. The system according to claim 1 wherein the control system controls, enables and authorizes access to the input of power into the battery and controls and monitors the amount of power entering the battery for accounting, charging and billing purposes.

27. The system according to claim 1 wherein the control system controls, enables and authorizes access to and monitors the output and the amount of power from the battery for charging and billing purposes.

28. The system of claim 1 wherein in the battery is a swap battery.
