Inductive power transfer pad, system for inductive power transfer and method of operating 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, wherein the movable part is movable between a retracted state and an extended state,whereinthe power transfer pad is designed or controllable such that the movable part is only movable to a position from a set of predetermined positions, wherein the set of predetermined positions is a subset of the set of all positions between the retracted and the extended state,whereinthe power transfer pad is controllable interval-dependent, wherein the retracted state is assigned to a first interval of ground clearances of a set of chargeable vehicles and the extended state is assigned to another interval of ground clearances of the set of chargeable vehicles, wherein the power transfer pad is designed or controllable such that in the retracted state and the extended state a minimal air gap height is provided, and wherein the minimal air gap height is larger than zero.

Abstract
Provided herein is an inductive power transfer pad for inductive power transfer to a vehicle. The inductive power transfer pad includes a stationary part and a movable part. The movable part includes a primary winding structure. The movable part is movable between a retracted state and an extended state. The power transfer pad is designed or controllable such that the movable part is only movable to a position from a set of predetermined positions. The set of predetermined positions is a subset of the set of all positions between the retracted and the extended state. A method of operating an inductive power transfer pad and an inductive power transfer system are also provided herein.

14. A method of operating an inductive power transfer pad, wherein the power transfer pad comprises a stationary part and a movable part, wherein the movable part comprises a primary winding structure, wherein the movable part is movable between a retracted state and an extended state,
wherein the movable part is only moved to a position from a set of predetermined positions, wherein the set of predetermined positions is a subset of the set of all positions between the retracted state and the extended state, wherein the power transfer pad is controlled interval-dependent, wherein the movable part is moved to the retracted state if a vehicle with a ground clearance of a first interval of ground clearances of a set of chargeable vehicles is to be charged, wherein the movable part is moved to the extended state if a vehicle with a ground clearance of another interval of ground clearances is to be charged, wherein the power transfer pad is designed or controlled such that in the retracted state and the extended state a minimal air gap height is provided, and wherein the minimal air gap height is larger than zero.
