FLAT COIL FOR A CONTACTLESS INDUCTIVE ENERGY TRANSMISSION
First Claim
1. An inductive energy transmission system for the transfer of electrical energy between a base station and a movable consumer, the energy transmission system being able to transfer electrical energy from a base station to the consumer and/or from the consumer to the base station, said energy transmission system comprising:
- at least one primary-side flat coil, arranged in the base station and having a plurality of turns arranged concentrically or spirally around a center and a relative spacing at least between some adjacent turns, anda flat coil arranged on the secondary side in the consumer and having a plurality of turns arranged concentrically or spirally around a center,wherein a distance between a turn arranged closest to the center and a turn arranged furthest from the center in the at least one primary-side coil is greater than in a secondary-side coil.

Abstract
The invention relates to an inductive energy transmission system for the transfer of electrical energy between a base station and a movable consumer, in particular a vehicle, the energy transmission system being able to transfer electrical energy from a base station to the consumer and/or from the consumer to the base station, said energy transmission system comprising at least one primary-side flat coil (Sp), arranged in the base station, and a flat coil (Ss) arranged on the secondary side in the consumer, having a plurality of turns (3, 4) in each case, the turns (3, 4) being arranged concentrically or spirally around a centre (M), characterised in that there is a relative spacing (d1) at least between some adjacent turns (13) of a primary-side flat coil (Sp), and the distance (9, 10) between the turn arranged closest to the centre (M) and the turn arranged furthest from the centre (M) in the primary-side coil (Sp) is greater than in a secondary-side coil (Ss).
