Abstract
Exemplary embodiments are directed to wireless charging and wireless power alignment of wireless power antennas associated with a vehicle. A wireless power charging apparatus includes an antenna including first and second orthogonal magnetic elements for detecting a horizontal component of a magnetic field generated from a second charging base antenna. A processor determines a directional vector between the antennas.
Claims42
A method, comprising:
- detecting at least a portion of at least one signal including a horizontal field component of a magnetic field with at least one antenna including at least first and second orthogonally spaced magnetic elements within a wireless vehicle base integrated within an electric vehicle, the magnetic field generated from a wireless charging base;
- and
- determining a direction from the vehicle base to the charging base from the detected at least a portion of the at least one signal.
An apparatus, comprising:
- at least one first antenna having a first magnetic element and a second magnetic element, orthogonal to the first magnetic element, the at least one first antenna for detecting a horizontal component of a magnetic field generated from at least one second antenna, wherein the horizontal component of the magnetic field is directed toward the at least one second antenna;
- and
- a processor for determining a vector between the at least one first antenna and the at least one second antenna.
An apparatus, comprising:
- means for detecting at least a portion of at least one signal including a horizontal field component of a magnetic field with at least one antenna including at least first and second orthogonally spaced magnetic elements within a wireless vehicle base integrated within an electric vehicle, the magnetic field generated from a wireless charging base;
- and
- means for determining a direction from the vehicle base to the charging base from the detected at least a portion of the at least one signal.
An apparatus, comprising:
- a wireless power charging base including at least one antenna configured to be positioned within a vehicle parking area and;
- a transmitter for transmitting at least one signal for guiding an electric vehicle within the vehicle parking area to enable a vehicle base of the electric vehicle to be positioned proximate the charging base.
