IEC 62893-4-2 Liquid-cooled EV charging cable application
Products are IEC 62893-4-2 compliant and certified to IEC 61851-1 Mode 4 for use with thermal management systems; these cables are intended for conductive charging in circuits with thermal management systems specified in the IEC 61851-23 system , and used in vehicle connectors that meet the requirements of IEC TS62196-3-1.
It is mainly used for the connection between the DC electric vehicle charging pile and the electric vehicle, and it can also be used for the connection between the portable charging equipment and the charging power source.
The cable structure is mainly composed of the main core of power supply, ground wire, signal wire or shield wire set, return pipe, filler and reinforcing rope combination. DC+ and DC- conductors are immersed in the cooling medium to take away heat through the medium and form a cooling circuit through the circulation of the return pipe, which eventually carries a larger current with a smaller conductor cross-section to achieve the effect of high-power fast charging; the product feels good, oil-resistant, acid-alkali-resistant, water-resistant and wear-resistant. Acid and alkali resistant, water resistant, wear resistant, crush resistant, crack resistant, UV resistant and flame retardant; all materials comply with RoHS 2.0 & REACH environmental standards.
