Abstract: Guidance and alignment systems are disclosed for wireless charging systems to assist in aligning the transmitter and receiver inductive power transfer (IPT) couplers. These systems guide positioning and alignment to provide sufficient coupling between the transmitter and receiver IPT couplers. Exemplary systems provide a magnetic field sensor, magnetic field generator, and magnetic vectoring to determine a position of an electric vehicle or a wireless charging base. In a magnetic vectoring system, an alignment system comprising at least three coils (or similar circuits) on a magnetically permeable substrate receives a positioning magnetic field including modulated information signals and processes the received signal to generate an output for determining a position of the positioning magnetic field source relative to the magnetic field sensor position. The alignment system may further comprise a similar structure that generates the positioning magnetic field, that may include modulated information signals, based on input signals.

Abstract: An apparatus is disclosed for a hybrid foreign-object detection and position system. In an example aspect, a foreign object detection (FOD) system of the base power-transfer system detects a passive beacon of an electric vehicle power- transfer system based on a beacon loop of the passive beacon overlapping an array of FOD sense loops effective to cause a change in impedance or admittance of one or more of the FOD sense loops. In aspects, the impedance reflects a modulation signal from the passive beacon. A position detection system integrated with the FOD system determines a passive beacon response in the input data based on the modulation frequency from the passive beacon. Then, a position of the beacon loop is determined relative to the array of FOD sense loops using a result of the passive beacon response canceled from input data.
