PROTECTIVE EARTHING AND COOLING SYSTEM FOR A CHARGING PLUG, CHARGING PLUG AND CHARGING STATION FOR DISCHARGING ELECTRIC ENERGY TO A RECIPIENT OF ELECTRIC ENERGY

A protective grounding and cooling system for a charging plug includes at least one protective ground conductor contact for galvanic connection to a protective ground conductor, and at least one cooling device for dissipating heat generated in the charging plug. The cooling device is galvanically connected to the protective ground conductor contact. The cooling device has a protective ground conductor connection for at least partial galvanic connection to the protective ground conductor, and in that the protective ground conductor contact, the cooling device and the protective ground conductor connection are arranged such that the protective ground conductor contact is galvanically connected to the protective ground conductor connection by means of the cooling device.
