Abstract

A kit comprising an inductive charger having a first coil and a portable device having an energy store and a second coil coupled to the energy store whereby the energy store can be charged from a varying electrical field applied across the first coil, the charger and the device being configured remotely from the coils for encouraging coupling between the first and second coils when the charger and the device are located against each other.

Claims

1. A kit comprising an inductive charger having a first coil and a portable device having an energy store and a second coil coupled to the energy store whereby the energy store can be charged from a varying electrical field applied across the first coil, the charger and the device being configured remotely from the coils for encouraging coupling between the first and second coils when the charger and the device are located against each other.

2. A kit as claimed in claim 1, wherein the charger comprises a DC to AC converter for forming the varying electrical field across the first coil and a capacitor connected between the DC to AC converter and an energy store local to the charger by which the field is formed.

3. A kit as claimed in claim 1, wherein the charger comprises a receiver for receiving data indicative of one or more charging parameters and the charger is arranged to alter one or more characteristics of the varying electrical field in response to the received data.

4. A kit as claimed in claim 3, wherein the receiver is a radio frequency receiver.

5. A kit as claimed in claim 3, wherein the receiver is an optical receiver.

6. A kit as claimed in claim 3, wherein the receiver is connected to the coil and is capable of detecting the data by means of the coil.

7. A kit as claimed in claim 3, wherein the device comprises a transmitter for transmitting data capable of identifying a charging strategy to the receiver.

8. A kit as claimed in claim 1, wherein the charger comprises a central processing unit and a user interface whereby a user of the device can interact with the central processing unit for the provision of a non-charging function by the device.

9. A kit as claimed in claim 1, wherein the device is a mobile phone.

10. A portable charging device as claimed in claim 1, wherein the energy store of the device is a battery.

11. A kit as claimed in claim 1, wherein the charger and the device are configured by means of mutually interlinking physical features remotely from the coils for encouraging coupling between the first and second coils when the charger and the device are located against each other.

12. A kit as claimed in claim 1, wherein the charger and the device are configured by means of mutually attracting magnetic features remotely from the coils for encouraging coupling between the first and second coils when the charger and the device are located against each other.

13. A kit comprising an inductive charger having a first coil and a portable device having an energy store and a second coil coupled to the energy store whereby the energy store can be charged from a varying electrical field applied across the first coil, the charger comprising a receiver for receiving data indicative of one or more charging parameters and the charger being arranged to alter one or more characteristics of the varying electrical field in response to the received data.

14. A kit as claimed in claim 13, wherein the charger comprises a DC to AC converter for forming the varying electrical field across the first coil and a capacitor connected between the DC to AC converter and an energy store local to the charger by which the field is formed.

15. A kit as claimed in claim 13, wherein the receiver is a radio frequency receiver.

16. A kit as claimed in claim 13, wherein the receiver is an optical receiver.

17. A kit as claimed in claim 14, wherein the receiver is connected to the coil and is capable of detecting the data by means of the coil.

18. A kit as claimed in claim 13, wherein the device comprises a transmitter for transmitting data capable of identifying a charging strategy to the receiver.

19. A kit as claimed in claim 13, wherein the charger comprises a central processing unit and a user interface whereby a user of the device can interact with the central processing unit for the provision of a non-charging function by the device.

20. A kit as claimed in claim 13, wherein the device is a mobile phone.

21. A kit as claimed in claim 13, wherein the energy store of the device is a battery.
