Abstract

A technology for a wireless transfer station that is operable to wirelessly transfer energy. Energy can be wirelessly transferred with a device or another wireless transfer station using an energy transfer platform having at least one surface. The energy transfer platform can comprise a plurality of wireless transfer coils, wherein the plurality of wireless transfer coils include at least one resonant charging coil and at least one inductive charging coil. Controlling a plurality of wireless transfer coils using a power management module.

Claims

1. A wheeled cart for wirelessly transferring energy, the wheeled cart, comprising:

a wheeled cart;

a work surface coupled to the wheeled cart;

a first wireless transfer station integrated into the work surface, wherein the wireless transfer station comprises;

a first wireless transfer platform; and

a first wireless transfer coil located within the first wireless transfer platform for wirelessly transferring energy; and

a first conversion module coupled to the first wireless transfer coil and configured to;

switch the first wireless transfer coil between a transmit mode and a receive mode; and

switch the first wireless transfer coil between a resonance charging mode and an induction charging mode.

2. The wheeled cart of claim 1, wherein the first wireless transfer station further comprises a battery.

3. The wheeled cart of claim 2, wherein the first wireless transfer station is operable to receive energy from another wireless transfer station to recharge the battery of the first wireless transfer station.

4. The wheeled cart of claim 2, further comprising an external wireless transfer station removable from the wheeled cart, wherein the external wireless transfer station comprises:

a second wireless transfer platform; and

a second wireless transfer coil located within the second wireless transfer platform for wirelessly transferring energy; and

a second conversion module coupled to the second wireless transfer coil and configured to;

switch the second wireless transfer coil between a transmit mode and a receive mode; and

switch the second wireless transfer coil between a resonance charging mode and an induction charging mode.

5. The wheeled cart of claim 4, wherein the first wireless transfer station is operable to receive energy from the external wireless transfer station to recharge the battery of the first wireless transfer station.

6. The wheeled cart of claim 4, wherein the external wireless transfer station is operable to provide partial energy to the wheeled cart when the external wireless transfer station is receiving energy from another wireless transfer station.

7. The wheeled cart of claim 4, wherein the external wireless transfer station is operable to provide energy to the wheeled cart when the one external wireless transfer station is receiving energy from another wireless transfer station.

8. The wheeled cart of claim 4, wherein the first wireless transfer station is operable to receive power from another wireless transfer station when the external wireless transfer station is removed from the wheeled cart for recharging.

9. The wheeled cart of claim 4, wherein the external wireless transfer station is integrated into a removable wireless energy battery pack.

10. The wheeled cart of claim 9, wherein, when the removable wireless energy battery pack is removed from the wheeled cart for recharging, the first wireless transfer station provides power to the wheeled cart.
