摘要： The present disclosure describes an induction charging device for a partially or fully electrically operated motor vehicle. The induction charging device includes at least one charging coil and a temperature-control assembly including a fluid pipe for a liquid fluid. The charging coil is inductively couplable to a primary coil such that a battery can be inductively charged in the motor vehicle. The charging coil is heat-transmittingly connected to the fluid pipe such that the waste heat from the charging coil can be transmitted to the fluid. The induction charging device further includes a metal shielding plate for shielding electromagnetic field emissions, and a ferrite assembly for directing an electromagnetic alternating field. The charging coil is arranged in the fluid pipe such that the fluid can flow around it on all sides. The charging coil is secured in the fluid pipe directly or via a retaining device.

摘要： A surface mountable housing for a power transmitter for wireless power transfer includes a connector system configured for use to mount, at least, a transmitter antenna to an underside of a structural surface, such that the transmitter antenna is configured to couple with a receiver antenna of a power receiver when the receiver antenna is proximate to a top side of the structural surface. The surface mountable housing further includes a heat sink, the heat sink configured to rest, at least in part, below the transmitter antenna, when the power transmitter is connected to the structural surface, and configured to direct heat generated by the power transmitter away from the structural surface, and an antenna housing, the antenna housing substantially surrounding a side wall of the transmitter antenna, the antenna housing connected to the heat sink and positioned between the heat sink and the structural surface.

摘要： A tile is provided with built in wireless power transfer technology that enables power to be wirelessly transferred from a wireless power transfer resonator of the tile to a wireless power receiver device of the tile. The wireless power receiver device includes, or is electrically coupled to, one or more electrical devices disposed on a front surface of the tile that are to be power by the receiver device. An array of the tiles may be provided in which case each tile has a wireless power transfer resonator. At least one of the tiles of the array is electrically coupled to an RF power source. The EM field generated by each tile is inductively coupled from that tile to a nearest-neighbor tile of the array.

摘要： A wireless charging device according to one implementation embodiment comprises a flow path arranged inside a magnetic unit or at an adjacent portion, and has cooling fluid flowing into the flow path so as to come in contact with the magnetic unit, and thus the heat generated during wireless charging can be readily discharged. Therefore, the wireless charging device can be effectively useful for a moving means such as an electric vehicle that requires high-capacity power transmission between a transmitter and a receiver.
