wherein at least one of the energy transfer module and the electronic unit is thermally connected to a cooling element via at least one heat conductor unit, the cooling element structured and arranged to communicate a through-flow of fluid.

2. The stationary induction charging station according to claim 1 , wherein:
the cooling element is fluidically connected to a fluid circuit,
a fluid conveying device is provided to convey a fluid through the fluid circuit, and
wherein the fluid absorbs waste heat when flowing through the cooling element.

3. The stationary induction charging station according to claim 2 , wherein the fluid is electrically insulating in the fluid circuit.

4. The stationary induction charging station according to claim 2 , wherein the fluid is a liquid.

5. The stationary induction charging station according to claim 2 , wherein at least one the fluid is enclosed in the fluid circuit against a surrounding area of the fluid circuit and the fluid in the fluid circuit is fluidically separated from a surrounding area of the fluid circuit.

6. The stationary induction charging station according to claim 2 , wherein the fluid is electrically insulating in the fluid circuit, and flows through a housing interior of a housing that at least partially defines the cooling element, and wherein the fluid at least one of at least partially wets inner surfaces of the housing interior, flows directly around the inner surfaces, and flows directly against the inner surfaces.

7. The stationary induction charging station according to claim 2 , wherein the fluid circuit includes at least one heat exchanger.

8. The stationary induction charging station according to claim 7 , wherein the heat exchanger is integrated in at least one of a local heat network and a district heat network.

9. The stationary induction charging station according to claim 7 , wherein the heat exchanger is structured and arranged as a liquid-air heat exchanger that transfers heat energy absorbed by the fluid to ambient air.

10. The stationary induction charging station according to claim 7 , wherein the heat exchanger transfers heat energy absorbed by the fluid to a surrounding area.

11. The stationary induction charging station according to claim 7 , wherein the heat exchanger is thermally connected to a heat storage device.
