Abstract
A wireless charging system includes a wireless power receiver, at least one receiver-side magnetic coupling member, a wireless power transmitter and at least one transmitter-side magnetic coupling member. The receiver-side magnetic coupling member is disposed on the wireless power receiver. The transmitter-side magnetic coupling member is disposed on the wireless power transmitter and is configured to attract the receiver-side magnetic coupling member. At least one of the wireless power receiver and the wireless power transmitter is movable.
Claims13
A wireless charging system, comprising:
- a wireless power receiver comprising a power receiving coil;
- at least one receiver-side magnetic coupling member disposed on the wireless power receiver, wherein the at least one receiver-side magnetic coupling member is arranged around the power receiving coil and is spaced apart from the power receiving coil;
- a wireless power transmitter comprising a power transmitting coil;
- and
- at least one transmitter-side magnetic coupling member stationarily disposed on the wireless power transmitter and configured to attract the at least one receiver-side magnetic coupling member, wherein the at least one transmitter-side magnetic coupling member is arranged around the power transmitting coil and is spaced apart from the power transmitting coil;
- wherein at least one of the wireless power receiver and the wireless power transmitter is movable, wherein the wireless power transmitter is electrically coupled to a power source, the wireless charging system further comprises a contact sensor and a switch, the switch is connected between the wireless power transmitter and the power source, when the contact sensor detects the wireless power transmitter being in contact with the wireless power receiver, the switch allows the power source to deliver electric power to the wireless power transmitter.
A wireless charging station, comprising:
- a base;
- a wireless power transmitter disposed on the base and comprising a power transmitting coil;
- and
- at least one magnetic coupling member stationarily disposed on the wireless power transmitter, wherein the at least one magnetic coupling member is arranged around the power transmitting coil and is spaced apart from the power transmitting coil;
- wherein the wireless power transmitter is electrically coupled to a power source, the wireless charging station further comprises a contact sensor and a switch, the switch is connected between the wireless power transmitter and the power source, when the contact sensor detects the wireless power transmitter being in contact with a wireless power receiver, the switch allows the power source to deliver electric power to the wireless power transmitter.
A vehicle, comprising:
- a vehicular body;
- a wireless power receiver disposed on the vehicular body and comprising a power receiving coil;
- and
- at least one magnetic coupling member disposed on the wireless power receiver, wherein the at least one magnetic coupling member is arranged around the power receiving coil and is spaced apart from the power receiving coil;
- wherein the at least one magnetic coupling member comprises an electromagnet, wherein the wireless power receiver is connected to an energy storage device, the vehicle further comprises an energy level detector, when the energy level detector detects that an energy level of the energy storage device reaches a predetermined energy level, the electromagnet ceases generating magnetic field.
A wireless charging station for charging a vehicle having a wireless power receiver, the wireless charging station comprising:
- a base disposed on a wheel-equipped carrier;
- a wireless power transmitter disposed on the base;
- and
- a positioning device disposed on the base and configured to detect the wireless power receiver, wherein when the wireless power receiver is detected by the positioning device, the positioning device controls a moving direction of the wheel-equipped carrier to have the wireless power transmitter abut against and align with the wireless power receiver to perform wireless charging.
