Liquid-cooled EV charging Cable

Oil-cooled Cables

The application mode of the cables is mainly used to connect electric vehicle charging devices to the charging

infrastructure, thus providing fast power transmission to electric vehicles, and equipped with a certain number of

signal and control lines to ensure accurate control and safe and error-free operation of the entire charging

process.

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 cable use scenario is generally used in centralized charging stations, large

parking lots, hotels, garages and other areas.
