1. An induction charging device for a vehicle charging system, comprising:
at least one magnetic field conductor;
at least one control device;
at least one temperature-control device configured to temperature-control the at least one magnetic field conductor, the at least one temperature-control device having a temperature-control power that is preset via the at least one control device;
the at least one temperature-control device configured such that a temperature-control fluid is flowable therethrough;
at least one induction coil configured to at least one of transmit and receive a wireless energy transmission with a transmission power that is preset via the at least one control device;
the at least one temperature-control device and the at least one induction coil arranged spaced apart from one another with respect to an axial axis;
the at least one magnetic field conductor arranged between the at least one temperature-control device and the at least one induction coil with respect to the axial axis;
with respect to the axial axis, the at least one temperature-control device is disposed at least one of opposite a temperature-control side of the at least one magnetic field conductor and facing the temperature-control side;
with respect to the axial axis, the at least one induction coil is disposed at least one of opposite a coil side of the at least one magnetic field conductor and facing the coil side;
a first temperature sensor configured to determine a temperature-control-side magnetic field conductor temperature of the temperature-control side;
at least one of (i) a second temperature sensor configured to determine a coil side magnetic field conductor temperature of the coil side and (ii) a temperature-control fluid temperature sensor configured to measure a temperature-control fluid temperature of the temperature-control fluid in the at least one temperature-control device;
wherein the first temperature sensor and the at least one of the second temperature sensor and the temperature-control fluid temperature sensor are each communicatingly connected to the at least one control device; and
wherein the at least one control device is configured to limit a thermal load of the at least one magnetic field conductor.
