1. A heavy-current charging cable for charging an electric vehicle, comprising:
a central heavy-current wire configured for serving as ground, the central heavy-current wire comprising a central conductor and extending in a longitudinal direction;
a plurality of heavy-current power wires configured for conducting positive and negative direct current, DC, the heavy-current power wires surrounding the heavy-current central wire, and each of said 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 a 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 an additional liquid coolant to flow between the inner hose and the outer hose along the longitudinal direction.
