Leoni is taking the development of wiring systems for demanding use in commercial vehicles to a new level, making them efficient, green and future-proof, from prototype to series production, making a significant contribution to the increasingly sustainable and networked mobility of tomorrow.
“As the nervous system of the commercial vehicle, our latest-generation wiring systems not only impress with improved performance values, but also reduce production costs at our customers‘ plants thanks to customized solutions. This applies to both the classic low-voltage segment and the high-voltage segment as one of the key components for commercial vehicles with alternative drive systems and increasingly automated functions. This is made possible by our in-depth expertise, from joint planning and project-specific concept development to the integration of the finished wiring system into the series model, all from a single source,” says Walter Glück, CTO of Leoni’s wiring systems division WSD.

As a partner in the government-funded ATLAS-L4 research and development project (Automated Transport between Logistics Centers on Level 4 Expressways), Leoni’s engineers are developing the redundant wiring system and the intelligent power distributors. Both components make a significant contribution to enabling highly automated trucks to drive on the motorway and thus ensure greater safety, efficiency and fewer traffic jams. ATLAS-L4 will be on show at the IAA Transportation 2024 in Hanover at the stand of project partner MAN Truck & Bus.
The liquid-cooled high-voltage cables from Leoni’s cable division ACS enable an immediate reduction in the CO2 footprint. Instead of traditionally relying on ever larger cable cross-sections to control the high heat generated by high current flows, Leoni Hivocar Cool cables have a coolant supply integrated into the cable. Compared to conventional charging cables, they reduce the cable weight by up to 75 percent. In addition, the liquid-cooled charging cables allow up to 2.5 times the current carrying capacity with correspondingly shorter charging times for commercial vehicles with electric motors.

Leoni’s developers always keep an eye on the effects of charging via the Megawatt Charging System (MCS) on each individual component of the vehicle electrical system. Highly integrated high-voltage distributors, for example, as well as optimized high-voltage wiring systems meet the performance requirements in terms of safety and energy efficiency and enable the wiring system to be optimally positioned in the commercial vehicle. Optional busbars in the overall wiring system also increase the degree of automation in final assembly for customers, which means faster installation times.
“Alternative drives, decarbonization, autonomous driving, connectivity: we help our customers to meet the challenges that the industry’s megatrends pose for the nervous system of their products. As a long-standing partner in the commercial vehicle market, Leoni is known for offering technically strong solutions worldwide. We offer real added value in the form of efficiency and sustainability,” says Xavier Paurise, CSO of Leoni’s wiring systems division WSD.
