Abstract: A power transmission apparatus for wireless power transfer to a movable power receiving apparatus includes a power transmission resonator that includes a power transmission coil and a transmission resonance capacitor unit, and a power transmission circuit for supply of alternating-current power to the power transmission resonator. The power transmission apparatus includes a power-transfer request signal receiver configured to receive a power-transfer request signal transmitted from the power receiving apparatus, and a switching unit. The switching unit is configured to, when the power-transfer request signal receiver receives the power-transfer request signal, change an input impedance of the power transmission resonator to change a value of current flowing through the power transmission coil of the power transmission resonator to a controlled value enabled to transfer power from the power transmission coil to the power receiving apparatus.

Abstract: A contactless power supply system for transferring power without contact between a primary side coil and a secondary side coil is provided. In the contactless power supply system, a manipulation unit manipulates a secondary side converter so that power outputted to a load is controlled to be a command value. The manipulation unit manipulates an input voltage of a primary side resonance circuit so that a current flowing in the primary side resonance circuit equals a product of a current flowing in the secondary side resonance circuit and a current coefficient. The current coefficient is defined as a square root of a specific value and the specific value is an equivalent resistance of the secondary side resonance circuit divided by an equivalent resistance of the primary side resonance circuit.

Abstract: A battery charger of a battery charging apparatus is disposed on an exterior case of an engine in such a manner that a generated heat is transferred therebetween. An ECU drives a cooling system when an engine temperature and temperature of the battery charger satisfy a predetermined cooling temperature condition. A cooling capacity for cooling the battery charger is improved by establishing a heat radiation passage to radiate a heat from the battery charger efficiently.

Abstract: A non-contact power supply device includes: a power transmission coil that generates a magnetic flux by an alternating current; a power transmission circuit that supplies the alternating current to the power transmission coil; a power transmission side control circuit that controls the power transmission circuit; a power receiving coil that generates an alternating current by interlinking the magnetic flux generated in the power transmission coil; and a power receiving circuit that converts the alternating current supplied from the power receiving coil into a direct current, and supplies the direct current to the power supply target. The power transmission side control circuit obtains a voltage vector target value based on a relationship between a voltage vector and a current vector, and controls the power transmission circuit to set the voltage vector of the alternating current output from the power transmission circuit to be the voltage vector target value.

Abstract: In an in-motion power supply system with a plurality of power supply segments to supply power to a vehicle, a vehicle position detection unit detects a position of the vehicle relative to each segment. An electrical characteristic acquisition unit acquires electrical characteristics in the segment involved in power transfer, and an abnormality determination unit uses the electrical characteristics to determine whether there is an abnormality in the segment involved in power transfer. The abnormality determination unit shares the electrical characteristics between a subject segment subjected to abnormality determination and at least one of a previous segment previous to the subject segment and a subsequent segment subsequent to the subject segment, and compares the electrical characteristics in the subject segment with at least either the electrical characteristics in the previous segment or the electrical characteristics in the subsequent segment to determine whether the electrical characteristics in the subject segment are abnormal.
