Battery swapping technology for electric trailers: a new era in logistics

DB Schenker, Trailer Dynamics, and CATL have embarked on an ambitious project to revolutionize the logistics industry with the introduction of battery swapping technology (BST) for electric trailers (eTrailers). On September 10, 2024, these three companies announced the start of a feasibility study that aims to implement and scale this technology across Europe.

The project is a critical step toward improving the efficiency and cost-effectiveness of battery-powered heavy-duty transport, setting the stage for a sustainable future in freight logistics. Through this initiative, the partners aim to establish battery swapping stations capable of serving the growing demand for electric trailers and potentially electric trucks throughout Europe.

Boosting efficiency with battery swapping

The proposed battery swapping system allows for the quick replacement of trailer batteries, significantly reducing downtime. Instead of waiting for traditional charging, which can take hours, the battery swap can be completed in just five minutes, enhancing vehicle availability and operational efficiency. By offering the option to use multiple battery modules based on specific use cases, logistics companies can optimize their fleet’s energy consumption and ensure that the right battery size is used for each journey.

This system not only minimizes the reliance on existing charging infrastructure but also enhances the overall economic viability of operating electric trailers in heavy-duty logistics. For an industry that relies heavily on uptime and precision, this could be a game-changer.

The role of each partner in the project

Each partner brings unique expertise to the table, contributing to the overall success of the project:

• Trailer Dynamics provides an innovative electric drivetrain solution that reduces diesel consumption and CO2 emissions, while also improving the range of electric trucks and trailers.
• DB Schenker, one of the largest logistics service providers in Europe, offers its extensive network and logistics management expertise. They are also responsible for identifying strategic locations for battery swapping stations across Europe.
• CATL, a global leader in battery technology, is tasked with adapting its battery solutions to the specific needs of the eTrailer concept and providing the necessary technical data for the design of battery swapping stations.

Paving the way for a sustainable future

By introducing battery swapping technology, the partnership aims to overcome the major hurdles facing electric heavy-duty transport—primarily charging infrastructure limitations and extended charging times. The new system supports the wider adoption of emission-free logistics by making electric trailers more accessible and practical for long-distance transport.

Wolfgang Janda, Executive Vice President of DB Schenker Europe, highlighted the importance of this innovation:

“Battery swapping technology will play a key role in addressing the challenges related to charging infrastructure and will support the rapid growth of emission-free heavy-duty transport, especially in Europe.”

Future expansion and demonstration

The project doesn’t stop with these three companies. The collaboration is expected to expand to include more logistics companies, energy providers, and service partners as the technology evolves. At the IAA Transportation 2024 event, Trailer Dynamics will present a prototype of an eTrailer equipped with a swappable battery. A live demonstration of the battery swapping process will be featured, showcasing the technology’s potential to streamline logistics operations.

As electric vehicles continue to reshape the landscape of freight transportation, the adoption of advanced solutions like battery swapping will be pivotal in driving the sustainability and efficiency of future logistics.
