Abstract: An abnormality determination apparatus includes a processing unit, a communication unit configured to communicate with a plurality of mobile bodies and a storage unit configured to store power reception history information received from each of the mobile body. The power reception history information includes a power receiving location of the received power received by the power receiving device, and a power transmission efficiency calculated based on the received power, or the received power. The processing unit is configured to extract information of the power receiving location where the power transmission efficiency is less than a predetermined value from the power reception history information of the plurality of the mobile bodies stored in the storage unit, and is configured to determine an abnormality of the power transmission device based on the information of the extracted power receiving location.

Abstract: A control device for power feeding during traveling includes a processor. Further, when a living object or a metal foreign object is detected around a primary coil of a power transfer device that transfers power to a power reception device of a vehicle that is traveling, the processor deletes identification information on the primary coil registered in an identification information list of the primary coil, and when the living object or the metal foreign object is not detected, the processor performs compatibility check and service authentication between the power reception device of the vehicle and the power transfer device.

Abstract: A combined metal object detection (MOD) and live object detection (LOD) system for a wireless power transfer (WPT) system in an electric vehicle (EV) charging application, and methods for use, are provided. The combined MOD and LOD system may comprise a transmitting pad, a detection coil pad coupled to the transmitting pad, and a receiving pad positioned adjacent to the transmitting pad. The transmitting pad, the detection coil pad, and the receiving pad may be configured such that, when a living object or a metal object appears between the transmitting pad and the receiving pad, an inductance or capacitance value change of the detection coil pad occurs.

Abstract: A wireless electric vehicle charging system comprises base-side equipment for generating a magnetic field and vehicle-side equipment for receiving energy via the magnetic field to supply power to a vehicle-driving battery. Monitoring circuitry monitors one or more of voltage, current, or phase associated with the base-side equipment and halts generation of the magnetic field in response to a change in the voltage, current, or phase associated with the operation of the base-side equipment that indicates a fault condition at the vehicle-side equipment, which may include a loss of power or disconnection of a battery. Based on detection of the change, the monitoring circuitry can halt generation of the magnetic field to prevent damage at the vehicle-side equipment.

Abstract: A power feed system includes a power feed mat. The power feed mat includes a plurality of power transmission coils. The power feed mat is configured to feed power to at least one movable body on the power feed mat by using at least one of the plurality of power transmission coils. The power feed system further includes a computer. When the computer restricts power feed to at least one movable body among a plurality of movable bodies on the power feed mat, the computer selects the at least one movable body power feed to which is to be restricted, based on a priority of each of the plurality of movable bodies.
