Press releases | 10/19/2018 New Product Range: Liebherr Supplies Charging Cable Cooling Units for E-mobility Charging Stations

Liebherr-Transportation Systems has been selected by ITT Cannon to supply active cooling units for its liquid cooled DC High Power Charging (HPC) solution. This contract enables Liebherr to contribute significantly to the further development of electro-mobility. Initial units of the cooling units, cables and connectors have already been delivered for assembly in EV ultra-fast charging stations in the USA and Europe.

The prototypes of the active cooling units - also known as Thermal Conditioning Units (TCU) - have been developed by Liebherr-Transportation Systems GmbH & Co KG, Korneuburg (Austria) specifically for e-mobility charging stations and were extensively and successfully tested beforehand by ITT Cannon, together with Efacec’s Electric Mobility division, one of the world leaders in fast and superfast charging. Liebherr's technology cools the innovative high-performance ITT Cannon HPC charging cable and connector to reliably limit a rise in temperature during the charging process.

Ralf Glocker, Senior Product Manager, ITT Cannon, commented during the climate chamber testing: "The cooling performance has exceeded our expectations.”

Feedback has been very positive, not only from the testing but also from field use. Reliability under all environmental conditions is an outstanding feature of the combination of the Liebherr cooling unit and the ITT Cannon solution. The concept is therefore very well positioned in the competition for the best solution and is increasingly in demand from customers.

The TCUs, in combination with the liquid-cooled cable and CCS connector, enable charging of electric vehicles. Installation in the first high-power charging station network, with an output power of 350 kW, a maximum current of 350 A and a high voltage of 1,000 V, have taken place in both the USA and Europe. In addition, the Liebherr team is developing additional cooling units to meet the increasing market requirements.

The cable cooling systems are a new solution for an e-mobility application and thus represent – in addition to, for example, cooling units for e-bus batteries – a new business area for Liebherr-Transportation Systems. The company is working together with ITT Cannon, part of ITT Inc. – a diversified leading manufacturer of highly engineered critical components and customized technology solutions for the energy, transportation and industrial markets.

The order for the charging stations will contribute to the continuous and long-term expansion of Liebherr's position in the growing and very promising market of cooling systems for rapid charging stations for electric vehicles.
