Title:
COIL UNIT AND ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2013/156169
Kind Code:
A3
Abstract:
The invention relates to a coil unit (6) for an electric vehicle (5) for the inductive transfer of electrical energy between the coil unit (6) and a stationary charging station, wherein the coil unit (6) comprises at least one coil (12) and a flux guide unit (14) for guiding a magnetic flux occurring during operation of the coil (12). The invention also relates to an electric vehicle (5) having a coil unit (6) for the inductive transfer of electrical energy between a secondary coil (12) of the coil unit (6) and a primary coil (8) of a charging station. The invention solves the problem of allowing the safe use of the inductive electrical energy transfer in electric vehicles, in particular motor vehicles, by proposing a coil unit (6), in which the flux guide unit (14) has material weakenings (15; 19; 20; 22-26) and an electric vehicle (5) having such a coil unit (6).
