ITT Cannon using 3M Novec dielectric cooling liquid in high-power charging system

In July, ITT Inc.’s Cannon brand announced that Efacec Electric Mobility will use its High-Power Charging (HPC) solution, comprised of a connector, cable and cooling unit, to power highway-based EV charging stations across the United States and Europe. The DC liquid-cooled HPC solution enables charging up to 20 miles of range per minute of charge at 350kW—seven times faster than today’s 50kW DC chargers. As part of an extended collaboration, ITT Cannon and Efacec are currently testing a 500kW solution, further pushing the limits of speed and innovation.

The groundbreaking design concept on the DC liquid-cooled HPC solution utilizes 3M Novec Engineered Fluids dielectric cooling liquid that runs from the cable throughout the connector’s contact system resulting in outstanding heat dissipation performance. Unlike other liquid coolants on the market, 3M’s Novec fluids are dielectric, non-flammable and non-toxic with no compromise on worker safety or environmental sustainability.

The weight-optimized cable design and minimized cable diameter make it ergonomic, light and easy to use. ITT Cannon’s DC liquid-cooled HPC solution is available in CCS1 and CCS2 variants for North American and European markets respectively.



Charging 20 miles per minute may be good enough to go for the last few miles. The 500 KW units being tested may be able to transfer enough electrons for 30-32 miles if batteries can take it. A 700 KW unit could do up to 40 miles be minute?
