A major automotive supplier is at the forefront of advancements in heavy-duty transportation, particularly in the realms of fuel cell and electric vehicles. Their involvement in ongoing hydrogen engine projects and fuel cell vehicle development highlights their commitment to sustainable technologies. At the IAA Transportation event, the supplier is set to unveil a groundbreaking approach for a fuel cell truck, showcasing innovative features such as fuel cell peripherals, thermal management, and a fully functional e-axle with high-performance SCT e-motors. Additionally, the introduction of a new evaporative cooling system and a bionic fan for fuel cell and electric vehicles demonstrates their dedication to improving efficiency and performance. One of the key highlights is the SCT E-Motor from Mahle, renowned for its exceptional endurance and efficiency, making it an ideal choice for heavy-duty transportation in both electric trucks and fuel cell applications. The unveiling of a heavy-duty electric axle integrating two SCT E-Motors with a total output of 520 kW underscores the supplier's emphasis on high-performance electric drives. Moreover, engineers have combined the e-axle, battery cooling, and a fully functional fuel cell in a technology demonstrator for the trade fair. The new evaporative cooling system showcased at the event offers significant cooling capacity improvements, leading to reduced fan power requirements and up to a 1.5 percent decrease in hydrogen consumption. These advancements represent a significant step towards enhancing the efficiency and sustainability of heavy-duty transportation through innovative technologies.
