Abstract

A power distribution system for distributing electrical power to battery-powered electrical devices, in particular mobile telephones, comprises at least one power connector for connection to an electrical device of a user whereby to replenish the battery of that device in response to a requirement from the user for battery charging and a locking mechanism configured selectively to connect the power connector to a source of electrical power only in response to receipt of an authorisation signal. The locking mechanism comprises a receiver configured to receive the authorisation signal from a remote server via a telecommunications network.

Claims

1. A power distribution system for distributing electrical power to battery-powered electrical

devices, in particular mobile telephones, the system comprising:

at least one power connector for connection to an electrical device of a user whereby to replenish the battery of that device in response to a requirement from the user for battery charging; and

a locking mechanism configured selectively to connect the power connector to a source of electrical power only in response to receipt of an authorisation signal,

wherein the locking mechanism comprises a receiver configured to receive the authorisation signal from a remote server via a telecommunications network.

2. A power distribution system as claimed in claim 1 further comprising a current monitor configured to monitor the current supplied to an electrical device via the power connector.

3. A power distribution system as claimed in claim 2, wherein the locking mechanism is configured to disconnect the power connector from the source of electrical power in response to a signal from the current monitor indicative of the connection of a further electrical device to the power connector.

4. A power distribution system as claimed in claim 2 or 3, wherein the locking mechanism is configured to disconnect the power connector from the source of electrical power after a predetermined amount of charge has been provided to the electrical device.

5. A power distribution system as claimed in any preceding claim further comprising a visual indicator associated with the power connector, wherein the locking mechanism is configured to illuminate the visual indicator when the power connector is connected to the source of electrical power.

6. A power distribution system as claimed in any preceding claim, wherein the remote server is configured to receive a request from the user indicating the user'"'"'s requirement for battery charging and in response to the received request to obtain payment in respect of the battery charging and on confirmation of payment to send the authorisation signal to the locking mechanism.

7. A power distribution system as claimed in claim 6, wherein the server is configured to obtain payment, at least partially, from a third party other than the user.

8. A power distribution system as claimed in claim 7, wherein the third party is a mobile network operator providing a mobile network service to the user.

9. A power distribution system as claimed in any of claims 6 to 8, wherein the request is in the form of an SMS message to a predetermined telephone number.

10. A power distribution system as claimed in any of claims 6 to 8, wherein the request is in the form of an unanswered call to a predetermined telephone number.

11. A power distribution system as claimed in claim 9 or 10, wherein the predetermined telephone number selected by the user indicates to the server the particular locking mechanism to which the authorisation signal is to be sent.

12. A power distribution system as claimed in any of claims 6 to 8, wherein request is in the form of a mobile money transfer.

13. A system as claimed in an preceding claim, wherein the power source comprises a solar panel.

14. A system as claimed in any preceding claim, wherein the power source comprises a battery.

15. A system is claimed in any preceding claim, wherein the power connector is a USB connector.

16. Apparatus configured to operate as a locking mechanism in the system of any preceding claim.

17. Apparatus configured to operate as a server in the system of any preceding claim.

18. Computer software which configures general purpose data processing apparatus to operate as the apparatus of claim 17.
