The IAA Transportation Show in Germany showcased a wealth of diesel-focused technologies, reflecting a hopeful resurgence for the North American trucking industry, which has faced challenges in recent years. Attendees were treated to a preview of significant technological advancements poised to make waves across the Atlantic in the near future.
Clarios Unveils 24-Volt Battery for Heavy-Duty Trucks
One of the highlights came from Clarios, a global leader in low-voltage battery solutions. Chief Technology Officer Brian McKay revealed the company’s commitment to developing battery technologies tailored for the evolving power demands of heavy-duty trucks. As trucking integrates more electrical devices—including enhanced heating and cooling systems, auxiliary electric systems, and advanced “by-wire” technologies—the need for a robust onboard power supply has intensified.
In response, Clarios announced a collaboration with a prominent European truck manufacturer to create 24-volt lithium-ion batteries specifically for heavy-duty applications. The company is also exploring alternative technologies, such as sodium-ion batteries, which could potentially replace lithium-ion options in the future.
ZF Introduces Hybrid Truck Transmission
In light of the impending EPA Phase 3 Greenhouse Gas Emissions regulations, ZF has reintroduced hybrid-electric transmissions to the trucking market. Peter Laier, a member of ZF’s board of management, announced the launch of the TraXon 2 hybrid transmission, designed to facilitate purely electric driving functions for both hybrid and plug-in hybrid commercial vehicles.
Laier highlighted the advantages of hybrid transmissions, which can provide electric power to the drivetrain at low speeds—typically under 30 mph—addressing two significant issues: the high NOx emissions from cold diesel engines and the inefficiencies associated with low-speed operation. He acknowledged that while the shift to battery-electric vehicles is progressing slowly in some markets, bridging technologies like hybrid transmissions can significantly reduce CO2 emissions.
Cummins Launches Integrated HELM Drivetrain
Cummins introduced its new integrated drivetrain focused on the HELM engine platform, which allows for hybrid transmission options. The HELM platform is designed to accommodate multiple fuel types, including advanced diesel, natural gas, and zero-carbon hydrogen, derived from a common base block with interchangeable components.
Jennifer Rumsey, Cummins’ chair and CEO, emphasized the company’s ability to provide fully integrated powertrain solutions for fleets, thanks to its recent acquisitions of Meritor, Siemens Commercial Vehicles, and Jacobs Vehicle Systems. Each drivetrain will be equipped with advanced aftertreatment systems and technologies from Accelera by Cummins, further enhancing their performance and emissions profiles.
As the IAA Transportation Show demonstrated, the trucking industry is poised for a technological transformation, driven by innovations in battery technology, hybrid transmissions, and integrated powertrains. This evolution reflects a broader commitment to sustainability and efficiency in the sector.
