Description

Plug and method for plug-in connection Technical Field The invention relates to a plug for a plug connection for an electrically operable motor vehicle according to the preamble of claim 1. The invention further relates to a method. Background A charging cable for charging an energy store of a vehicle is described in DE102016216565 A1. The charging cable comprises a grid-side interface for contacting a grid interface, at which charging power with a grid voltage is provided. The first plug is used for transmitting current from the power grid to an AC/DC converter integrated in the first charging plug. The AC/DC converter converts alternating current to direct current. The direct current is then transmitted through the charging cable to a DC/DC converter in the vehicle that adjusts the voltage and DC level to a level suitable for the vehicle battery. This enables electrically operable motor vehicles or electric vehicles to be charged. The corresponding electronics for charging the high voltage vehicle battery are integrated in both plugs of the charging cable. In order to effectively lead out the generated power loss, a high-performance cooling system is provided. However, this cooling system occupies a significant portion of the available structural space. This results in disadvantageous component distribution and suboptimal heat dissipation in the prior art. Disclosure of Invention The object of the invention is to design a plug for a charging plug or plug connection such that a maximization of efficiency and power density and an extremely compact design are provided. This object is achieved according to the invention by a plug having the features of claim 1 and by means of a method according to the invention. Advantageous embodiments of the invention are the subject matter of the dependent claims and the description. The electronics for charging the high-voltage vehicle battery (which has an exemplary charging power of 11 kW) should be integrated into the two plugs of the charging cable in order to meet high demands on efficiency and power density and thereby achieve a solution that is as compact as possible. However, in the course of further developments of such solutions, the charging power may also increase even further in the future. The integration of the electronics for charging the high-voltage vehicle battery into the two plugs of the charging cable should therefore also be able to flexibly cope with these future demands for higher charging powers. A plug for a plug connection for charging an electrically operable motor vehicle is provided, comprising a housing, in which components of an electronic system and a first heat-conducting element are arranged. Accordingly, a plug is proposed, which is provided for a plug connection for charging an electrically operable motor vehicle, in particular a passenger vehicle. The plug comprises a housing in which the different components of the electronic system and the first heat conducting element are arranged. The electronic system is configured to provide all of the required functions. When the plug is plugged into the corresponding socket, the electronic system recognizes the power demand and transmits the required energy to the electronic system of the motor vehicle via the charging cable. This makes it possible to charge the electric motor vehicle. Heat is generated during the charging process, which results in energy loss. This energy loss is an integral part of the charging process and should be minimized as much as possible by the present invention to maximize the efficiency of energy transfer. One object of the present invention is to design a plug of a charging plug or plug-in connection in such a way that the efficiency and the power density are maximized and at the same time an extremely compact design is achieved. In order to solve the object of the invention and to design a plug for a charging plug or plug connection in such a way that efficiency and power density are maximized and at the same time an extremely compact design is achieved, it is provided that at least one second heat-conducting element is provided in addition to the first heat-conducting element in the housing. The first and the second heat-conducting element are arranged opposite one another in the interior of the housing, providing a receiving space in which the components of the electronic system arranged on the respective heat-conducting element and further components for tempering the electronic system and/or the plug are arranged. In other words, at least one second heat conducting element is provided in addition to the first heat conducting element. The two heat-conducting elements are arranged or fixed or mounted inside the housing and form a receiving space. In which different components of the electronic system and/or additional components for tempering the electronic system and/or the plug are arranged or fixed or mounted. By using a plurality of heat conducting element
