The Swiss company Huber+Suhner has presented a liquid-cooled charging cable system which is designed to enable continuous charging with 500 A even at very high temperatures of up to 50 degrees Celsius. With a voltage of 1,000 volts, charging capacities of up to 500 kW are conceivable.
The new rapid charging system called RADOX HPC500 builds on the performance and design of Huber+Suhner’s HPC400 family and is available with both CCS1 and CCS2 interface. Compared to the previously available rapid charging systems in the range, the new solution has been optimised to provide an improved protection class (IP67), calibration-compliant power measurement in the connector and replaceable power contacts for a longer service life, the Swiss company announced. In addition, the connector is 20 per cent lighter and the cable is more flexible.
The core of the cooled cable system at high ambient temperatures is a newly developed and additionally used 24V cooling unit. “Thanks to its higher cooling capacity, the operating temperature of the charging cables is reduced, which allows continuous charging with 500 A at ambient temperatures of up to 50 degrees Celsius,” the company’s headquarters says. It is a plug-and-play unit that also fits into existing charging stations and is already filled with a coolant ex-works. As far as the noise level is concerned, Huber+Suhner assures that the speeds of the fans on the heat exchanger and the feed pump are automatically controlled, which contributes to a “considerable reduction in noise emissions”.
“The improvements we have made to the entire HPC system make it a truly groundbreaking product, enabling continuous charging with currents of 500 A for the first time in the world,” says Max Göldi, Market Manager Industry at Huber+Suhner. The Swiss company is currently delivering its HPC charging systems to America and Canada on behalf of Electrify America. But the manufacturer is also involved in the rollout of many infrastructure projects in Europe.
Incidentally, Huber+Suhner also recently presented a new high-voltage distribution solution and integrated it into its high-voltage portfolio. Since then, the Swiss company has been offering a complete cable system as a ready-to-use plug-and-play solution.
