Abstract: A Protective Earth (PE) loss detection method for charging an electrical vehicle is provided. The electrical vehicle comprises an Electrical Vehicle Supply Equipment (EVSE), a charging connector, and/or a charging cable comprising at least a Proximity Pilot (PP) line for a PP signal, a Control Pilot (CP) line for a CP signal and a PE line for a PE signal. The method comprises detecting interruption of the PE line by observing a change of the PP signal.

Abstract: An electric vehicle charging equipment (EVSE) system is provided. The EVSE system delivers direct current (DC) charging power and is configured for delivering electrical energy to a single electrical vehicle at a same time. The EVSE system comprises a plurality of charging cables with respective charging connectors for connecting to a respective plurality of electrical vehicles. At least one of the plurality of charging cables is liquid cooled and each of the plurality of charging cables comprises at least two DC power lines and at least two signal lines, which are each connected to a respective DC power line within the charging connector. The EVSE system further comprises a DC metering device configured for measuring, via the at least two signal lines, a connector voltage between the at least two DC power lines within the charging connector.
