摘要： A full duplex, low latency, near field data link controls a resonant induction, wireless power transfer system for recharging electric vehicles. An assembly of a vehicle is aligned with respect to a ground assembly to receive a charging signal. The vehicle assembly includes one or more coils, each coil having a full duplex inductively coupled data communication system that communicates with a ground assembly including one or more coils, with each coil also having a full duplex inductively coupled data communications system. The coils of the ground assembly and the vehicle assembly are selectively enabled based on geometric positioning of the vehicle assembly relative to the ground assembly for charging. As appropriate, the transmit/receive system of the ground assembly and/or the vehicle assembly are adjusted to be of the same type to enable communication of charging management and control data between the ground assembly and the vehicle assembly during charging.

摘要： A wireless power transmission circuit for wirelessly transmitting line frequency sinusoidal AC power to a load where the line frequency ripple filter of conventional circuits is eliminated and a DC-to-AC inverter is replaced by a simple polarity inversion circuit. The envelope of the high frequency AC on the AC line frequency source side is not constant but varies continuously in a half-sinusoidal fashion at the line frequency. Wireless transmission occurs only with a half-sinusoidal, constantly varying envelope, not the constant amplitude envelope of prior art. High frequency rectification and high frequency ripple filtering occurs as in the prior art but the ripple filter time constant is selected so that resulting waveform is an accurate replica of the rectified line frequency voltage present on the transmitter side. A polarity inversion stage replaces the DC-to-AC inverter of conventional art to generate the line frequency AC.

摘要： A contactless battery system includes a sealable dustproof and waterproof case that houses a battery unit and at least one wireless power transmission coupler connected to the battery unit. The at least one wireless power transmission coupler is disposed with respect to at least one face of the sealable case to enable magnetic inductive signaling for charging, discharging, and communication with the battery.
Without physical contacts, the battery is inherently safe since voltage and current are not available to the touch. The lack of physical contacts also means that contact wear is eliminated and the battery modules have the benefit of inherent galvanic isolation. Since the battery system is sealed, internal intrusion detection systems may be used to detect improper attempts at battery changes or attacks on the electronics containing the usage and charging records in an attempt to increase the battery unit's value on the secondary battery market.

摘要： A vehicle alignment system is adapted to align a vehicle with a wireless power induction coil for wireless charging through use of magnetic resonant induction. The system includes a transmission line disposed in the parking slot so as to guide the vehicle to the wireless power induction coil for charging. The transmission line leaks a signal having an operating frequency that is detected to align the vehicle left-right in the parking slot when the vehicle is aligned for charging by the wireless power induction coil. At least two vehicle mounted antennas mounted on opposite sides of transmission line when the vehicle is aligned in the parking slot detect the operating frequency from the transmission line, and signal processing circuitry detects a relative signal phase between signals detected by the antennas that is representative of alignment of the vehicle with respect to the wireless power induction coil and the parking slot.

摘要： A full duplex, low latency, near field data link controls a static and/or dynamic resonant induction, wireless power transfer system used for recharging electric vehicles and other electrically powered devices. A coherent transponder configuration enables low complexity synchronous detection and positive rejection of signals originating from nearby and adjacent vehicles. A reference crystal oscillator in the ground side apparatus provides frequency synchronization for both the forward and the return data links. Transmission is by means of near field magnetic induction between pairs of loop antennas which, together with the effective waveguide below cutoff structure comprised by the vehicle underbody and the ground surface, largely restrict signal propagation to the area in the immediate vicinity of the system antennas.
