High-Voltage Plug Connection Part for a High-Voltage Plug Connector of a Motor Vehicle, High-Voltage Electrical System, and Motor Vehicle

A high-voltage plug connection part for a high-voltage plug connector of a high-voltage electrical system of a motor vehicle, the high-voltage electrical system, and the motor vehicle are disclosed herein. The high-voltage plug connector can be coupled to at least one high-voltage line. The high-voltage plug connection part has at least one integrated temperature sensor which is designed to detect a sensor signal that characterizes the temperature of the at least one high-voltage line and provide the detected sensor signal to an analysis device in order to monitor the temperature of the at least one high-voltage line.
