In this podcast episode 30, hosts Chris Sass and Niall Riddell from Paua, talk to industry leaders James Venables and Ibrahim Kraria from Daimler, about the latest advancements in EV technology, particularly in heavy-duty trucks. As the automotive industry shifts towards sustainable solutions, their insights shed light on what makes electric trucks a viable option for the future.

One of the focal points of the discussion was the evolution of battery chemistry in electric trucks. Initially, the team at Daimler employed nickel manganese cobalt (NMC) battery chemistry, which had established itself in passenger cars. This choice allowed for rapid market entry and compatibility with existing charging infrastructure. However, as technology progressed, they transitioned to lithium iron phosphate (LFP) battery chemistry for newer models, like the Next Generation eCanter and EATR 600.

James highlighted two significant advantages of LFP batteries: lower costs and higher usable energy density. The EATR 600 boasts an impressive 97% usable capacity, compared to just 75-85% for NMC batteries. This transition also ensures the longevity of the trucks, matching the design life of diesel trucks—around 10 years and 1.2 million kilometres.

The discussion also delved into the innovative E-Axle technology, which integrates the motors directly into the rear axle. This design not only improves efficiency but also enhances battery packaging. By eliminating the need for a separate engine and gearbox, the E-Axle allows for better range and reduces weight. For instance, the EATR 600 can achieve a range of over 300 miles (approximately 500 km) at 40 tons, offering a competitive edge in the market.

Ibrahim elaborated on the importance of battery packaging, stating that maximising battery capacity while ensuring safety is paramount. The strategic placement of batteries under the chassis not only optimises space but also enhances safety during side impacts.

Despite being electric, these trucks don’t compromise on comfort or technology. James emphasised the importance of safety features in their vehicles, which often surpass those found in traditional diesel trucks. For example, the trucks are equipped with Active Brake Assist 5, an autonomous emergency braking system with pedestrian recognition, which can stop the vehicle at speeds of up to 50 km/h.

In addition to safety, modern conveniences like Apple CarPlay and an optimised human-machine interface make driving easier and safer, ensuring that drivers have access to the same comforts they expect in traditional trucks.

As the conversation shifted to the future of alternative fuel technologies, the experts expressed a sense of urgency regarding the development of infrastructure. James pointed out that while battery electric vehicles (BEVs) are easier to scale due to existing charging networks, hydrogen technology requires significant investment in production and refuelling infrastructure.

Ibrahim emphasised the need for a rapid ramp-up in hydrogen production and the establishment of supply chains. Both experts agreed that government incentives and regulatory frameworks will be crucial for fostering innovation and encouraging investment in these technologies.

As electric trucks continue to evolve, innovations in battery technology and safety features are paving the way for a more sustainable future in transportation. The commitment from industry leaders like James and Ibrahim, coupled with advancements in infrastructure and government support, will be vital in driving the adoption of electric and hydrogen-powered vehicles.

In conclusion, this podcast highlights the critical steps needed to transition towards a zero-emission future. As the industry progresses, both James and Ibrahim remain optimistic about the potential of electric trucks and the role they will play in reshaping the commercial vehicle landscape.
