LIQUID COOLING OF EV CHARGING
AND EV FLEET OPERATIONS

DC fast charging relies on higher power — over 350kW or more in Extreme Fast Chargers (XFCs). That kind of power generates significant heat. As external converters and EV supply equipment controls are responsible for safely and effectively managing the higher power levels between the charger and an EV, they require effective thermal management. And this poses another challenge. A DC fast charger necessitates larger conductors. Along with increased charging speed and higher heat, the resulting cables can become bulky and unwieldy.

Liquid Cooling

High-power EV charging solutions require the benefits of liquid cooling. Compared to standard air cooling, liquid cooling offers more efficient heat dissipation — the key to unlocking higher performance and shorter charging times. Further, liquid cooled charging cables can use smaller conductors to reduce cable weight by up to 40%. That allows them to fit where other cables can’t, optimizing limited space. As an added benefit, lighter-weight cables are easier to handle for consumers, promoting safe and reliable operation.

LIQUID COOLING EV APPLICATIONS USE QUICK DISCONNECT COUPLINGS (QDs)

  • In the hose handle "Nozzle"

  • At the Inverter of the Charging unit near power source

  • As a part of distribution nodes of consolidated charging units

  • Within fleet battery charging bay station systems

  • On board vehicles, near battery and/or drive train systems

  • Anywhere else heat needs efficient dissipation

Our Solutions

Product Highlights

  • ​An ergonomically designed thumb latch provides both ease and speed of installation and system maintenance — just listen for the “click” to know you’re connected.

  • Blind mates provide access to power inverters at the back of HPCs no matter how hard to reach they may be and provide flow tolerances at connection. They can also compensate for axial tolerance variations in assemblies without sacrificing flow performance.

  • Optimized flowrates for superior performance.

  • A robust portfolio of QDs allow coolant to efficiently chill inverters, umbilicals and other components within your system.

  • Made of durable PPSU or metal and high-performance polymers that withstand pressures during installation and use (side load, flexing, tensile forces) for years of leak-free reliability.
