Munich. BMW Group Logistik has conducted successful test trials of an electric-powered semi-trailer in various real-world logistics scenarios. Teaming up with Trailer Dynamics, a technology innovator, the trials achieved significant fuel savings and increased range compared to diesel trucks. The combined use of an electric tractor and e-trailer enabled a range of over 600 kilometers without recharging. Testing was carried out over four days at the BMW Group location in Dingolfing for short and medium distances, and over three days between Mamming in Lower Bavaria and the BMW Group plant in Leipzig for long distances. These trials aimed to identify the best application scenarios for BMW Group Logistik using Trailer Dynamics’ e-trailer.
Michael Nikolaides, Head of BMW Group Production Network and Logistics, said, “The pilot testing with Trailer Dynamics’ e-trailer showed that using this kind of electrified semi-trailer significantly reduces the fuel consumption of standard diesel tractors and noticeably increases the range of e-trucks. The BMW Group is committed to complete climate neutrality throughout the entire value chain, and projects like this accelerate our Green Transport Logistics strategy.”
Key features of the e-trailer:
Unlike conventional semi-trailers, Trailer Dynamics’ e-trailer is equipped with its own battery and electric drive axle. The electric axle supports the semi-truck’s engine and ensures optimal load ratio for better fuel efficiency. Additionally, the powered axle provides extra power during startup and on slopes. Even if the e-trailer’s battery is empty, the combination with a diesel truck ensures a continuous power supply.
The medium-distance tests lasted four consecutive days, covering logistics routes around the BMW Group location in Dingolfing. With the support of logistics service provider Gahr International, up to 250 kilometers were covered per day on motorways and main roads. Data collection from both the e-trailer and tractor was carried out simultaneously for the first time, resulting in an average diesel consumption reduction of 46.59 percent.
Significant fuel savings over long distances:
In the long distance tests, conducted on real logistics routes with a load exceeding 16 tonnes, the e-trailer achieved diesel savings of over 48 percent on average compared to conventional trailers. The round trip between Leipzig and Mamming covered a distance of 450 kilometers mainly on motorways. The e-trailer’s battery was charged using 100 percent green energy, resulting in a potential CO2 reduction of approximately 120 tonnes per year when applied on a larger scale.
100 percent CO2 reduction with an e-truck:
Combining an e-trailer with an electric tractor powered by 100 percent green electricity can achieve a 100 percent reduction in CO2 emissions while enabling long-distance routes. This scenario was demonstrated using a Volvo e-truck on the final day of medium-distance testing, achieving a driving distance of over 600 kilometers without recharging.
The use of e-trailers results in fuel savings but is counterbalanced by the heavier weight and lower payload capacity. However, this is partially offset by the increased permissible total weight for trailers in the EU. Although the initial costs of e-trailers are higher, they can result in lower operating costs. Over long distances, implementing e-trailers can significantly decarbonize the existing fleet and save costs.
Trailer Dynamics aims to contribute to decarbonizing the economy by promoting sustainable and ideally zero-emission logistics through the use of e-trailers. With the support of BMW, forwarding agents Gahr International and Elflein Spedition & Transport, the test drives represent an important step towards realizing this vision, according to Abdullah Jaber, CEO and Managing Director of Trailer Dynamics.
These visionary e-trailer pilot projects align with the BMW Group’s commitment to implementing their Green Transport Logistics strategy. By supporting the development of innovative technologies in transport logistics, BMW aims to reduce CO2 emissions and improve their overall environmental footprint.
