Abstract

A base station for providing inductive transfer of energy to a mobile device that includes a base unit having an inductive transmitter coil configured to generate an electromagnetic field in response to an electrical charge being applied to the inductive transmitter coil with an adapter separate from the base unit. The adapter can include an inductive charging circuitry for controlling the current transmitted through the inductive transmitter coil.

Claims

1. A base station for providing inductive transfer of energy to a mobile device comprising:

a base unit comprising an inductive transmitter coil configured to generate an electromagnetic field in response to an electrical charge being applied to the inductive transmitter coil; and

,

an adapter separate from the base unit, the adapter comprising an inductive charging circuitry for controlling the current transmitted through the inductive transmitter coil.

2. The base station of claim 1, wherein the inductive charging circuitry includes a circuit board having electrical components for controlling the current transmitted through the inductive transmitter coil.

3. The base station of claim 1, wherein the adapter comprises a plug.

4. The base station of claim 1, further comprising a cable connecting the base unit to the adapter separate from the base unit.

5. The base station of claim 1, wherein the base unit comprises additional inductive transmitter coils disposed off-set from one another.

6. The base station of claim 5, wherein the base unit comprises at least three transmission coils, wherein at least one transmission coil of the at least three transmission coils overlaps with two other transmission coils.

7. The base station of claim 1, wherein the adapter is disposed in a plug configured to engage with an electrical socket and the base unit is disposed in a dashboard mount for a portable electronic device.

8. The base station of claim 1, wherein the adapter is disposed in a plug configured to engage with an electrical socket and the base unit is disposed in a tabletop.

9. The base station of claim 1, wherein the adapter and the base unit are disposed in a portable rechargeable battery with the adapter and the base unit being seperate.

10. A method comprising:

receiving direct current electrical charge at an adapter separate from a base unit comprising one or more transmission coils;

receiving a signal from a mobile device requesting power, the mobile device adjacent a base unit, the base unit being physically separate from the adapter;

converting the direct current electrical charge to alternating electrical charge by the adapter;

transmitting the alternating electric current from the adapter to one or more transmission coils disposed in the base unit.

11. The method of claim 10, wherein the base unit and the adapter are connected by an electrical cable.

12. The method of claim 11, wherein the electrical cable is flexible.

13. The method of claim 10, wherein the one or more transmission coils includes at least two off-set transmission coils disposed in the base unit.
