To help meet this challenge, ITT Cannon - a diversified manufacturer of highly engineered critical components and customised technology solutions for multiple markets including transportation and industrial - has developed a game-changing liquid cooled DC High Power Charging (HPC) solution.

This uses a lightweight cable and 3M™ Novec™ Engineered Fluid as a high-performing coolant to give an ultra-fast charge at a level of 500A at 1,000V that can deliver a 60-mile range charge in as little as three to five minutes.

Novec Engineered Fluids deliver excellent performance in many heat transfer applications, with no compromise to worker safety or environmental protection. The fluids are dielectric and non-flammable, making them a more sustainable alternative to traditional cooling fluids such as mineral oils and water glycol, that can be used to cool electric vehicle charging cables.

The cooling process takes place both in the connector and cable, enabling the heat generated to dissipate quickly. This allows the charging solution to maintain a unique temperature profile.

Liquid cooling is pivotal to the ITT Cannon Cooled DC High Power Charging solution, for both performance and safety. It also provides a better user experience which was of critical importance to ITT Cannon. Without liquid cooling, the cable would be much more bulky and heavy, making it hard to handle for many users.

Said Ralf Glocker, ITT Cannon’s senior product manager for Electrical Vehicle solutions: “From the beginning, our engineering team was focused on a prime handling experience. We considered all those who might not have the physical strength of an average person, who need to be able to easily handle the equipment as well. Based on our best-in-class quality pledge, we understood that we could only achieve this with a liquid-cooled solution.

“Liquid cooling allows us to reduce the cable weight by about 40 per cent. We identified that by cooling the connector itself internally, instead of just the cable, we could keep the temperatures as low as possible.”

The flexible, ergonomic and easy-to-use charging solution is viewed by ITT as a real enabler for helping quicker electric vehicle charging go mainstream. Ralf Glocker added: “ITT has been supplying the leading charging station manufacturers with trial units for several months and is now getting ready to deliver fully industrialised and certified solutions to support the major deployments of high power charging corridors globally.”
