  • Non-contact charging devices for wireless energy transmission for charging electric vehicles are known from the prior art. These usually have a primary charging ⁇ unit, which may be arranged, for example, stationary, and a secondary charging unit, which is arranged on the motor vehicle on. The energy transfer from the primary charging unit to the secondary charging unit is usually effected via an inductive coupling of the primary charging unit to the secondary charging unit.
