Huber+Suhner has launched the first cooled charging cable system that allows continuous fast charging at 500A even in high-temperature environments.

The Radox HPC500 cable and connector builds on the HPC400 family with several improvements and new features that make the system ready for existing and future requirements. These enhancements include continuous 500A charging, an IP67 connector protection rating, the option of a ready-to-use metering system and replaceable contacts for longer service life.

Alongside the cooled cable system, the company has also developed a new 24V cooling unit to increase cooling capacity and reduce operational temperatures of the power lines, enabling the continuous 500A charging at environmental temperatures of up to 50 ºC.

The plug-and-play cooling unit is pre-filled with coolant and is designed to fit into existing charging stations, significantly reducing installation time. The speed of both the ventilators on the heat exchanger and the coolant pump is automatically adjusted to achieve the most efficient performance, with normal operating levels requiring lower speed, significantly reducing noise level.

The design of the HPC500 reduces the connector weight by 20 per cent and improved cable flexibility compared to the previous model of the HPC system offers easier handling for end-users.

“The improvements we have made to the complete HPC system make this a truly ground-breaking product which enables continuous charging at 500A for the first time,” said Max Göldi, Market Manager Industry at Huber+Suhner. “This helps charging station operators prepare for the future with an improved return on investment.”

The HPC systems are currently installed across the US and the company is also part of EV roll out initiatives across Europe.
