1. An electromagnetic induction charging device for an inductive, in particular contactless, charging of an at least partially electrified motor vehicle with electrical energy, the electromagnetic induction charging device comprising:
a housing, formed in a pot-like manner, which comprises a pot base and a pot collar, wherein the pot collar, facing away from the pot base, surrounds a pot opening;
a thermally conductive cover, which covers the pot opening such that, together with the housing, it delimits a housing interior;
an electromagnetic resonator, arranged in the housing interior, for the inductive transmitting of electrical energy to the motor vehicle,
wherein the housing comprises a thermal insulation which is arranged at the pot collar and at the pot base for the thermal insulating of the housing interior with respect to the external environment.
