Abstract: A vehicle is provided with a coil and a sensor. The coil is adapted to receive power wirelessly in single-phase form from an external coil. The sensor is adapted to measure a characteristic of the power. The vehicle is also provided with a controller that is programmed to estimate a parameter indicative of coil alignment using a three-phase representation of the power based on the characteristic, and to adjust the power received by the coil based on the parameter.

Abstract: A charger system and method is disclosed for providing wireless and wired charging. The charger may include a wire-charging circuit operable to receive and process a first electrical energy from a wired power source directly connected to the vehicle. The charger may also include a receiving coil operable to receive a second electrical energy received from a wireless power source external that is not directly connected to the vehicle. The charger may include a resonant circuit having a receiving coil and a DC-DC converter. The receiving coil may provide impedance matching when the charger is receiving the first electrical energy from the wired power source. The receiving coil may also be energized by a wireless power source to receive a second electrical energy. The charger may further include a rectifier circuit operable to charge the battery using the first electrical energy or the second electrical energy.

Abstract: A DC to DC power converter includes a switching circuit and an LC filter configured to reduce parasitic inductance. The LC filter includes an inductor, capacitor, and a coil positioned and oriented relative to and electrically connected with the capacitor. The coil positioned with the capacitor provides the ripple current caused by operation of the switching circuitry to flow through the capacitor and coil with opposite direction. The ripple current flowing through the coil attenuates a magnetic field generated by the capacitor while reducing parasitic inductance of the capacitor.

Abstract: A DC to DC power converter includes switching circuitry and an LC filter. The LC filter includes a capacitor electrically connected between an inductor and coil. The inductor and coil are wound in a same direction. The coil is positioned and oriented relative to the inductor so that current from the switching circuitry flowing through the inductor and coil results in inductive coupling between the inductor and coil. This coupling increases a frequency at which a parasitic inductance and capacitance of the capacitor resonate.

Abstract: Electric vehicle supply equipment includes at least first and second connectors, and a controller. The controller, responsive to detecting the first and second connectors are engaged with first and second vehicles respectively, synchronizes electric power from the first and second vehicles and supplies the electric power to an entity other than the first and second vehicles.

Abstract: A vehicle system includes a controller configured to, responsive to an alignment mode, disable a power rectifier configured to transfer charge between a secondary coil and battery, and enable a precision rectifier to output a voltage responsive to current induced in the secondary coil resulting from current through a corresponding primary coil, and responsive to the voltage exceeding a threshold, enable the power rectifier and disable the precision rectifier.

Abstract: A parameter estimation system includes a first coil configured to be loosely inductively coupled to a second coil. A controller is programmed to output parameters of the first coil and second coil. The controller is programmed to estimate the parameters based on voltage and current measurement from only the first or the second coil. The voltage and current measurements may be used in a Kalman filter. In some configurations, the controller is further programmed to command a short circuit between terminals of the second coil and apply a test voltage to the first coil. The first coil may be part of a vehicle charging station and the second coil may be part of a vehicle. The parameters may be utilized to control charging of the vehicle.

Abstract: A wireless vehicle charging system includes at least one controller configured to operate an inverter to control a voltage input to a power converter in a vehicle to drive an impedance phase angle at an output of the inverter toward a predetermined angle and achieve a power demand at an output of the vehicle power converter. The at least one controller is further configured to operate the vehicle power converter to achieve the power demand. The at least one controller may control a frequency output of the inverter to adjust the voltage input to the power converter based on a rate of change of an objective function that is configured to reduce an output power error of the power converter and an impedance phase angle error at the output of the inverter.
