Abstract

A coil unit for inductive transmission of energy includes a coil and a flux management unit to manage a magnetic flux during operation of the coil. The flux management unit is arranged behind the at least one coil, when viewed along a coil axis of the coil, and includes at least two flux management sectors and a channel between the flux management sectors. At least partially accommodating the coil and the flux management unit is a housing. A supporting element is arranged between a housing base and a housing lid and configured such that a projection of the supporting element along the coil axis is congruent with or lies within an extent of the flux management unit. A force acting on the housing lid can be diverted via the supporting element past the at least one coil and the at least two flux management sectors to the housing base.
