Stäubli Electrical Connectors is focused on achieving the fastest charging times in the heavy electric vehicle sector. Their progressing partnership with cable manufacturer Leoni has led to significant advancements in EV charging performance.

The dynamic commitment of the two companies Stäubli and Leoni goes beyond the framework of a traditional partnership and focuses on an open exchange of expertise and resources. The integration of Leoni's knowledge about the subtleties of cooled cables was crucial from the start and enabled Stäubli to quickly gain a foothold in this complex area.

"Together with Leoni, we were able to deepen our knowledge and understand the entire system of cables and connectors. With their extensive expertise in cooled cables, Leoni helped us to gain a lead and further develop our high-performance charging solutions. Now we are continuing the technical exchange for several projects and are proud to collaborate with such an experienced company as Leoni," says Mathieu Chaligné, ACS project manager at Stäubli, about the collaboration.

Both companies have conducted several tests in Leoni's test center, including more than five intense test weeks for Stäubli's next generation of the rapid charging plug QCC. While both the QCC and the MCS (Megawatt Charging System) are supposed to use similar technologies, both companies were able to test values up to 5,000 A with the QCC. These tests were crucial for the refinement of the next QCC developments, to ensure they meet the strict requirements of mining equipment. In addition, Leoni helped Stäubli in defining the best technical solution for the various MCS charging currents solutions.

"At LEONI Charging & Power Solutions, we are always very interested in future technologies and high-tech solutions to advance electrification in all areas. Especially in close collaboration, we can benefit from the in-depth expertise of both partners and develop demanding solutions for the upcoming fully electric society. I am proud that we can support our customers not only with cables, but also with testing and simulation services." Sebastian Goß, Head of Product Management DC / HPC at Leoni.

Another test round has been confirmed for the new QCC-5000, after which Stäubli expects the inauguration of its own facility in Hésingue, France. Nevertheless, the technical dialogue between the two companies continues, underlining a constructive and future-oriented relationship.

In addition, both companies are aware that cables and connectors are inextricably linked when it comes to performance. The innovation initiated by the partnership with Stäubli has led to an improved approach to integrating cooled cables with their MCS and QCC products. This holistic perspective ensures that the integrity of the overall system is not compromised in the development of individual components.

With a focus on MCS products and the further development of the next generation of QCC, the collaboration between Stäubli and LEONI promises to drive the industry forward and offer high-performance rapid charging solutions tailored to heavy electric vehicles. Both companies have the entire spectrum in view and ensure that cables and plugs are not only compatible, but also exceed expectations. Stäubli will be showcasing its latest QCC developments for the mining industry at the MINExpo in Las Vegas later this year. (kr)
