Liquid-cooled charging cables feature both a power connector and a separate liquid connector for the cooling circuit. These connectors are designed to be drip-proof for safer maintenance.

Step-by-Step Connection:

1. Connecting the Cooling Line: Locate the liquid-cooling connectors on the charging station's cable and the vehicle's port. Push them together until they click or lock into place.
2. Connecting the Power Cable: Once the cooling line is established, connect the CCS2 main power plug to the vehicle's charging port.
3. Starting Charging: The system automatically detects the active cooling circuit and power connection before initiating the high-power flow.

A coolant (typically a water and glycol mixture or silicone oil) circulates through channels in the cable and connector, absorbing heat directly where it is generated. The heated liquid then returns to the cooling unit within the station to dissipate heat before recirculating.

System Advantages: This technology enables power levels up to 800kW, prevents overheating, and allows for thinner, lighter, and more ergonomic cables.
