DRIVE
September 6, 2023
The invention relates to a liquid cooled cable arrangement for high-power fast charging of electric vehicles, comprisinga charging connector (1) and a liquid cooled charging cable (2), wherebythe liquid cooled charging cable (2) comprises a plurality of conductors (3) for supplying charging current and at least two fluid channels (4) for supply and return liquid coolant,the charging connector (1) comprises a plurality of bus bars (6) and a plurality of contacts (8),each one conductor (3) is electrically and thermally connected to one bus bar (6) and via the bus bar (6) to one contact (8), andthe charging connector (1) comprises a second part (7) consisting of a thermally conductive and electrically insulating material to which the bus bars (6) are attached and to which the fluid channels (4) are thermally connected such that heat generated in the contacts (8) during charging can be removed by the liquid coolant, and/orthe bus bars (6) comprise bus bar fluid channels (10) to which the fluid channels (4) are thermally connected such that heat generated in the contacts (8) during charging can be removed by the liquid coolant.
