Claims15
A charging system for an electric energy storage comprising a cable charging assembly, a plug transition between said charging cable assembly and said electric energy storage, said cable charging assembly comprising a cable provided with at least two separate power conductors and at least one earth conductor, wherein the at least two separate power conductors are spaced a distance apart from each other within said cable, each power conductor surrounds at least one tube, and each power conductor comprises a plurality of intertwisted wires stranded around said tube, wherein said cable charging assembly comprises at least two separate cooling circuits within said cable, namely a first cooling circuit comprising a cooling fluid in the tubes surrounded by the at least two power conductors and a second cooling circuit comprising a cooling fluid in auxiliary tubes to cool the plug transition.
A method for charging an electrical energy storage comprising:
- a base station, a charging cable assembly connected with the base station and a plug transition between the charging cable assembly and the electric energy storage, wherein the charging cable assembly is provided with at least two separate power conductors, at least one earth conductor and at least two auxiliary tubes, wherein each power conductor surrounds a tube, wherein a first cooling fluid is pumped from the base station through the tubes surrounded by the at least two separate power conductors and wherein a second cooling fluid is pumped from the base station through the auxiliary tubes for cooling the plug transitions.
