Abstract
A coil unit for an electric vehicle for the inductive transfer of electrical energy between the coil unit and a stationary charging station. The coil unit includes at least one coil and a flux guide unit for guiding a magnetic flux occurring during operation of the coil. Also disclosed is an electric vehicle having a coil unit for the inductive transfer of electrical energy between a secondary coil of the coil unit and a primary coil of a charging station. The disclosed coil 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, in which the flux guide unit has material weakenings, and an electric vehicle having such a coil unit.
