Introduction to high-power DC liquid-cooled charging cable

China [CN]

High-power DC charging cable is a solution that uses liquid cooling technology to keep the cable at a low constant temperature during the charging process by cooling and cooling, overcoming the heat damage to the charging gun, charging cable, and charging pile caused by heating, thereby increasing the DC charging current. The principle is to add a liquid cooling circulation system inside the cable, and connect it through a sealed circulation inside the charging gun, so that the cooling system and the charging system coexist and work together. It is the latest technology that can fully charge the car battery in a short time, or quickly replenish the power to increase the driving range, meet customer needs, increase the utilization rate of electric vehicles, and eliminate user charging anxiety. Product reference standard: IEC62893.4.2-2021

Among them, a high-power charging pile cable features: It includes a main power core, an auxiliary power core, a charging communication core, a detection communication optical unit, an outer cooling pipe, a central cooling pipe, a wrapping tape, an inner sheath, a shielding reinforcement layer, and an outer sheath. The charging communication core is a 2-to-2 core twisted structure, which is cabled together with the detection communication optical unit to form a detection control unit of a charging pile cable, and is arranged tangentially with the main power core; the auxiliary power core is composed of a conductor and insulation, and the two auxiliary power cores are symmetrically distributed on both sides of the detection control unit composed of the charging communication core and the detection communication optical unit, and are tangential to the main power core.

Any high-power electric vehicle charging cable needs to be provided with solution services by a professional cable manufacturer. Welcome to visit OMG Cable Manufacturer: https:/www.omgevcable.com
