German logistics giant DB Schenker signed cooperation agreement with Krone and Trailer Dynamics to purchase up to 2,000 e-trailers, in order to significantly reduce carbon emissions. As we wrote in this post, the electrified trailers from Trailer Dynamics have an electric drivetrain that makes it possible to support the drive of the tractor unit.

Krone e-trailers with Trailer Dynamics recuperation technology

A specially developed component uses a patented sensor system to determine the driving dynamics of the tractor-trailer combination and then readjusts the e-trailer so that the e-trailer itself supports the tractor unit. The latter cannot be overridden at any time, however. The electric drive train also allows energy to be recovered during braking. The e-trailer’s drive control system operates independently, so no interface with the tractor is necessary.

The trailers can be equipped with 300 kWh, 450 kWh, or 600 kWh batteries as required. This can extend the range of electric tractors by up to 500 km, depending on the use case, and also significantly reduce the fuel consumption of conventional diesel tractors. CO2 emissions can thus be reduced by 20%-40%.

Statements from DB Schenker and Krone

“This agreement marks a further step in the electrification of land transport,” commented Cyrille Bonjean, Executive Vice President Land Transport for DB Schenker in Europe. “It is essential for us to look for new sustainable solutions that can be integrated into our daily business. With the eTrailer from Trailer Dynamics, we have obtained another promising model for the future.”

“Electrification, digitalization, automation, and decarbonization are the strategic goals that Krone will achieve with its innovative products – and especially the eTrailer. We are therefore very pleased that we not only share these goals with our long-standing customer DB Schenker; we are also jointly making them a reality with this eTrailer project”, added Stefan Binnewies, CEO of Krone Holding.
