INDUCTIVE POWER TRANSFER DEVICE AND SYSTEM FOR INDUCTIVELY CHARGING A WATER-BOUND VEHICLE AND METHOD FOR OPERATING AN INDUCTIVE POWER TRANSFER DEVICE

摘要

An inductive power transfer device 10 for inductive power transfer to a water vehicle such as a boat has a power transfer part 12 comprising a primary conductor arrangement such as a coil or winding, and a kinematic unit 14 for moving the power transfer part 12, comprising a linear guide 24 oriented such that when the power transfer part 12 moves along the guide 24 it moves vertically. The linear guide 24 may be substantially vertical. A folding arm 15 may allow movement to the power transfer part 12 in the horizontal plane. The power transfer part 12 may have a protective layer. A floatable buoyant member 60 may be provided, coupled to the moving power transfer part 12. An actuator 51 may be provided to cause movement of the power transfer part 12. A method of operation is also disclosed. The device enables close coupling for efficient inductive charging in spite of rising and falling tidal levels.
