Abstract: A method and system for detection of an electric vehicle via a two-line bus includes a detection unit for detecting a presence status of an electric vehicle. The electric vehicle connects to a charger having the detection unit. The detection unit includes a first output for driving a two-line bus, which connects the charger and the electric vehicle; and a first input for receiving signals from the two-line bus. An additional input detects a second bus termination arranged within the electric vehicle through a voltage measurement and/or a current measurement of the two-line bus, wherein detecting the second bus termination is an indication of the presence status of the electric vehicle.

Abstract: A DC contactor arrangement for bidirectional power switching includes a DC+ contactor for connecting a power source with a load, and a DC− contactor for connecting the power source with the load. At least one of the DC+ or DC− contactors is a unidirectional DC contactor. The DC+ contactor and the DC− contactor are configured to be switched at different times, when the DC+ contactor and the DC− contactor are under load.
