Quick Coupling Solutions for Electric Vehicles
For electric vehicles (EV) to reach their global breakthrough, charging must become more accessible, faster and more efficient. The higher output generates more heat and that requires effective thermal management. Liquid cooling fulfils the cooling requirements and quick couplings help facilitate the installation, reliability and maintenance.
Liquid cooling has proven successful in high-performance computing and it is now a key to break the barrier for fast and efficient charging in electric vehicle charging stations.
Quick couplings have proven efficient to facilitate thermal management for Electric Vehicles within several parts of the solutions:
- Quick connect couplings for fast-chargers and reliable charging infrastructure with efficient installation and maintenance
- Charging cable with integrated cooling connectors
- Onboard liquid cooling solutions for vehicle battery packs, inverters and electric motors
Enable efficient fast-charging with quick couplings
Quick couplings play an important role in liquid cooling systems and could be the components that elevate the whole design to enable fast charging of battery electric vehicles (BEVs). A typical 22 kW AC charger provides enough charge in 120 minutes to provide an additional 200 km of vehicle range. To reduce the 200 km range charge time to only 16 minutes, a 150 kW DC charging station is required. At this level of power, and to avoid overheating, an effective and improved thermal management is needed as the temperature can increase to more than 270°C during a 10-minute fast charge.
High cooling demands when industrial vehicles go electric
Battery-driven vehicles have made their way into the professional segment. Reduced greenhouse gas emissions, less toxic fumes and less noise pollution from city buses, construction machines, short-distance ferries, agriculture and mining vehicles are some clear advantages of switching to electric.
The high battery power output requires onboard liquid cooling with reliable quick connect solutions to facilitate charging cooling performance and also for thermal management of batteries, electric motor and inverters during operation.
“The CEJN ultraFLOW works very well when connecting and disconnecting the liquid cooling system as the couplings are easy to connect, is lightweight, and ensures no-spill”

Non-spill couplings secure the operation
With non-spill quick couplings, you can work with pre-filled systems to make maintenance easier and there is no spill during disconnection. The installation and maintenance on-site can be made quickly as there is no need for filling the system with cooling liquid or evacuating air from the system.
The benefits of pre-filled cooling modules for electric vehicle charging
With quick couplings, there is the possibility to work with pre-filled cooling modules that can give long-term benefits for the overall investment:
1. Saves time on installation and maintenance
2. No draining and filling on site
3. Guaranteed no spill with quality clean-break quick couplings
