Abstract
Techniques for wirelessly transferring energy to a vehicle are disclosed. An example method for wirelessly transferring energy to a vehicle according to the disclosure includes detecting a ripple frequency on a transmitter coil circuit, such that the ripple frequency is associated with a vehicle switch mode controller frequency of a switch mode controller in the vehicle, and providing an electrical current to a coil in the transmitter coil circuit based at least in part on the ripple frequency.
Claims30
A method for wirelessly transferring energy to a vehicle, comprising:
- detecting a ripple frequency on a transmitter coil circuit, wherein the ripple frequency is associated with a vehicle switch mode controller frequency of a switch mode controller in the vehicle;
- and
- providing an electrical current to a coil in the transmitter coil circuit based at least in part on the ripple frequency.
An apparatus for wirelessly transferring energy to a vehicle, comprising:
- a transmitter coil circuit including a coil;
- a ripple detector operably coupled to the transmitter coil circuit;
- at least one processor operably coupled to the transmitter coil circuit and the ripple detector and configured to:
- receive a ripple frequency from the ripple detector, wherein the ripple frequency is associated with a vehicle switch mode controller frequency of a switch mode controller in the vehicle;
- and
- provide an electrical current to the transmitter coil circuit based at least in part on the ripple frequency.
An apparatus for wirelessly transferring energy to a vehicle, comprising:
- means for detecting a ripple frequency on a transmitter means, wherein the ripple frequency is associated with a vehicle switch mode controller frequency of a switch mode controller in the vehicle;
- and
- means for providing an electrical current to the transmitter means based at least in part on the ripple frequency.
A non-transitory processor-readable storage medium comprising processor-readable instructions configured to cause one or more processors to control a wireless charging system, comprising:
- code for detecting a ripple frequency on a transmitter coil circuit, wherein the ripple frequency is associated with a vehicle switch mode controller frequency of a switch mode controller in a vehicle;
- and
- code for providing an electrical current to a coil in the transmitter coil circuit based at least in part on the ripple frequency.
