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: A system and method for heavy-current charging cables for charging an electric vehicles includes a central heavy-current wire extending in a longitudinal direction, a plurality of heavy-current power wires comprising a power conductor and a power wire insulation surrounding said power conductor, the heavy-current power wires extending parallel to the central wire, a liquid tight inner hose extending in the longitudinal direction and surrounding the heavy-current central wire and the heavy-current power wires thereby defining a first hollow area comprising liquid coolant to flow between the heavy-current central wire and the heavy-current power wires along the longitudinal direction, and a liquid tight outer hose extending in the longitudinal direction and surrounding the inner hose thereby defining a second hollow area comprising liquid coolant to flow between the inner hose and the outer hose along the longitudinal direction.
