To enable continuous high-powered electric vehicle charging, even in high-temperature environments, a new charging cable system has been launched that can operate at 500 Amperes thanks to a cooling system.

Huber + Suhner, an electrical and optical connectivity company, has revealed its Radox HPC500, which is the world’s first cooled charging cable system that allows continuous charging at 500 Amperes.

The HPC500 cable and connector uses a cooled cable in order to deliver its performance, as well as an IP67 connector protection rating from the outside elements.

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

The new plug-and-play cooling unit, which is pre-filled with coolant, fits 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.

In addition to this, a 20% reduction in the connector weight 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 500 A 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.”
