Hybrid Storage: Maximizing Charging Efficiency and Range for Semi-Trucks

As part of the “evTrailer2” collaborative research project, we have developed a hybrid energy storage system for heavy-duty semi-trailer trucks. The system combines high-energy and high-power cells, enabling high charging power while reducing charging times. Optimized charging cycles extend battery life and increase the range of electric trucks. Transportation and logistics companies, as well as manufacturers in the field of electromobility, stand to benefit most from these results.

In the “evTrailer2” project, project partners from industry and academia investigated the potential of electrified semi-trailer systems for long-haul transport and combined innovative technologies to improve energy efficiency in heavy-duty transport. The goal was to significantly reduce fuel consumption and greenhouse gas emissions from heavy semi-trailer trucks (N3, over twelve metric tons). By optimizing an electrically powered semi-trailer for so-called “traction cooperation” with the tractor unit, reductions of 30 to 40 percent in greenhouse gas emissions were achieved.

From Research to Your Application

How can high-performance energy storage systems be integrated into various mobile and stationary applications in a cost-effective, durable, and efficient manner?

The technologies and methods developed in the “evTrailer2” project can be applied to numerous applications. We support companies in developing hybrid energy storage systems as well as intelligent operating, charging, and energy management strategies for electrified systems with high performance and efficiency requirements.

The focus is on applications with dynamic load profiles, high charging and regenerative braking capacities, and requirements for range, service life, and operating costs—for example, in commercial vehicles, mobile machinery, rail vehicles, maritime applications, and industrial and fast-charging systems.
