Inductive Power Transfer with Inductive Power Transfer Pad
First Claim
1. An inductive power transfer pad for inductive power transfer to a vehicle, comprising a stationary part and a movable part, wherein the movable part comprises a primary winding structure for generating a magnetic or electromagnetic field while an electric current flows through windings of the primary winding structure, wherein the inductive power transfer pad comprises at least one actuator for actuating motion of the movable part, wherein the movable part is movable at least into a first direction by the at least one actuator so as to move between a retracted state and an extended state,wherein:
- the stationary part comprises operating devices, which are electric and/or electronic devices adapted to operate the primary winding structure so that the primary winding structure generates the magnetic or electromagnetic field, wherein the operating devices are electrically connected to the primary winding structure and produce heat during operation;
the stationary part comprises a cooling device which is thermally coupled to the operating devices and is adapted to transfer heat to an environment of the inductive power transfer pad; and
the cooling device is covered by the movable part in the retracted state and the movable part uncovers the cooling device while being moved into the extended state.
