1. An inductive power transfer pad for transmitting wireless power to a wireless power receiver seperable form the inductive power transfer pad, the inductive power transfer pad comprising:
- one or more ferromagnetic slabs in a first layer;
a coil having at least one turn of a conductor, the coil being arranged in a second layer substantially parallel to that of said ferromagnetic slabs; and
a shield member comprising a backplate defining a third layer, said backplate arranged to control said magnetic field generated by said coil.

Abstract
An inductive power transfer (IPT) pad and system for the charging of electric and hybid electric vehicles. The batter of such a vehicle can be selectively coupled to a high power electrical supply for fast charging or a lower power electrical supply for charging using IPT. The batteries of the vehicles are used in a system to control the load demand in an electricity network through variations of the frequency of power supplied.

17. An inductive power transfer pad for transmitting wireless power to a wireless power receiver seperable from the inductive power transfer pad, the inductive power transfer pad comprising:
-
means for generating a magnetic field in a first layer; means for controlling said magnetic field, said means for generating said magnetic field arranged in a second layer substantially parallel to that of said means for controlling said magnetic field; and means for shielding against said magnetic field, said means for shielding further defining a third layer and arranged to control said magnetic field generated by said means for generating said magnetic field. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
