Description

technical field

[0001] The invention relates to a device for conducting electrical energy by means of an electrical conductor surrounded by at least one electrically insulating second layer, the device having at least one temperature sensor for detecting the temperature of the electrical conductor, wherein The temperature sensor is disposed between the electrical conductor and the second electrically insulating layer. Background technique

[0002] Devices of this type for conducting electrical energy are used, for example, in cables or electrical plug connections for charging electric vehicles. What is required for charging an electric vehicle is the transfer of a large amount of charge to the battery of the electric vehicle in a relatively short period of time. In order to keep the time for charging short, the charging power must be correspondingly high, ie a large amount of charge must be transferred to the battery in a relatively short time. This results in a correspond...

Embodiment Construction

[0025] exist figure 1 An electrical conductor 1 (for example a cable or a plug connector) is shown by way of example in FIG. 2 , wherein the electrical conductor 1 is surrounded by a first layer 3 which is designed to be electrically insulating and thermally conductive at the same time. Around the first layer 3 there is provided an electrically insulating and at the same time thermally insulating second layer 4 which is in turn surrounded by an outer third layer 5 which insulates the cable from the external environment. The third outer layer 5 must be neither electrically nor thermally insulating, and it can only be equipped with the outer shape of the cable or the connector depending on the design. Inside the electrically insulating and thermally conductive first layer 3 there is a temperature sensor 2 which detects the temperature of the electrical conductor 1 . This happens in that when the electrical conductor 1 heats up, the heat is transferred to the temperature sensor ...
