摘要： A charging station includes a plurality of electric power transmission portions and a power supply ECU. When a second vehicle is parked at a position where it can receive electric power from a first electric power transmission portion and when the second vehicle receives weak electric power from the first electric power transmission portion, the second vehicle transmits to the power supply ECU, an occupation signal which allows determination that the parking position corresponds to the first electric power transmission portion. When the power supply ECU receives the occupation signal of the first electric power transmission portion from the second vehicle, the power supply ECU stops transmission of weak electric power from the first electric power transmission portion and guides a first vehicle to a second electric power transmission portion.

摘要： The invention provides a coil apparatus (100) for inductive power transmission, comprising an electromagnetic coil (102) for emitting and/or picking up an electromagnetic field (112) on a transmission side (106) of the coil apparatus (100), and comprising a housing wall (104), which covers the coil (102) on the transmission side (106) and is transmissive to the electromagnetic field (112). Furthermore, the coil apparatus (100) comprises a housing medium (108), which is enclosed by the housing wall (104) in such a way that, when a through-opening (110) is formed in the housing wall (104), the housing medium (108) passes through the through-opening (110). Alternatively, a housing vacuum is provided which is enclosed by the housing wall in such a way that, when a through-opening is formed in the housing wall, atmospheric air (118) passes through the through-opening. Among further aspects, a vehicle comprising such a coil apparatus and a method for inductive power transmission are provided. The method comprises steps of providing an electromagnetic coil (102) for emitting and/or picking up an electromagnetic field (112), covering the coil (102) on a transmission side (106) with a housing wall (104) which is transmissive to the electromagnetic field (112), enclosing a fluid (116) with an internal pressure which is different than the atmospheric air by the housing wall (104), sending the internal pressure, evaluating whether the internal pressure reaches a presettable internal pressure threshold value, and outputting a signal when the internal pressure reaches the internal pressure threshold value.

摘要： A non-contact power transmitting/receiving system calculates a loss Plo as a power difference between a transmitted power Ptr of a power transmission unit of a power transmission device and a received power Pre of a power receiving unit of a power receiving device. The non-contact power transmitting/receiving system sets a smaller value to a target transmitted power Ptr* when the calculated loss Plo is greater than a reference value Ploref, than a value when the calculated loss Plo is equal to or less than the reference value Ploref, and controls a high-frequency power circuit with the set target transmitted power Ptr*.
