3kW 4.6kW Integrated Liquid Cooling System for CCS1 CCS2 GBT Cable

A 3.5kW 4.6kW 7kW liquid cooling system typically refers to a high-powered, water-cooled unit for applications like an induction heater, which is used for metal heating in workshops.lt is applicable to submersed liquid-cooling charging station.3kW 4.6kW 7kW 9kW CCS2 Integrated Liquid Cooling System .The dielectric cooling liquid in the HPC solution cools both the cable and the connector's contact system resulting in extremely effective heat dissipation.

The integrated liquid cooling system for electric vehicle charging stations utilizes coolant circulation technology to control the heat generated during rapid charging through high-power charging cables and internal components. The working principle of the CCS2 integrated liquid cooling system is that the coolant circulates through dedicated channels in the charging cable and connector, thereby dissipating the heat generated during high-speed DC fast charging. The system is integrated into charging stations and vehicles, using a power pump to circulate coolant from the charging unit to the cables and back to the integrated cooling unit within the charging station, thereby supporting currents exceeding 250A. This can prevent the charging gun and cable from overheating, achieving faster and safer charging.

working principle

Integrated cooling: The cooling system is a closed-loop system integrated into the charging station and charging cable.

Coolant circulation: The power pump circulates coolant (such as water ethylene glycol mixture) to a dedicated channel in the charging cable.

Heat dissipation: The coolant flows through the connector and surrounds the DC power contact cavity (where the maximum heat generation occurs). It absorbs heat and brings it back to the cooling unit of the charging station.

Heat exchange: Heat is then dissipated from the coolant, usually through the radiator and fan in the charging station, and the cooled liquid is then pumped back into the cable.

High power capability: The continuous circulation of coolant can efficiently dissipate heat, resulting in a charging current exceeding 250A, which can cause overheating in air-cooled systems.

Key Features

Integrated system: The cooling system is integrated into the charging station and cables, without the need to install a separate cooling unit on the vehicle.

Safety: The system includes a temperature sensor to monitor the DC power contacts and prevent overheating, ensuring a safe charging process.

Performance: Achieve ultra fast charging by efficiently dissipating heat directly from the charging contacts.

Coolant selection: Depending on the specific system, this system can be compatible with multiple types of coolants, such as water ethylene glycol mixtures.
