Plug connector for attaching direct current charging socket of charging cable to battery of motor car, has contacts for energy transmission, and serial interface for serial data transmission

摘要

The connector (1) has contacts (2a, 2b) for energy transmission, and a serial interface (4) for serial data transmission. The serial data transmission is formed with a radio interface or an optical interface via the serial interface for electrical connection of data lines. A ground contact (5) allows grounding of an electric vehicle. A discharging resistor for discharging an electrical charge is switched to the contacts. A temperature sensor measures the temperature of the connector. An ammeter measures charge current and a voltage measuring device measures charging voltage.
