The businesses carried out 4 days of exams over distances of as much as 250 kilometers every day on motorways and foremost roads. Three days of check drives protecting the 450 kilometers between Leipzig and Mamming carried a great deal of greater than 17 tons of power modules for BMW electrical automobiles, primarily on motorways.

Based on BMW, the common gas financial savings in comparison with a standard semi-trailer had been greater than 46% over brief and medium distances and greater than 48% over lengthy distances. The mixture of electrical tractor and e-trailer achieved a variety of greater than 600 kilometers on a full cost.

The Trailer Dynamics e-trailer has its personal battery and electrical drive axle, which helps the tractor’s engine. Built-in sensors on the kingpin between tractor and trailer preserve an optimum load ratio to realize optimum gas financial system. The axle additionally provides extra energy throughout start-up and on slopes.

“The gas financial savings when utilizing e-trailers are counterbalanced by their heavier weight and the ensuing decrease payload, however that is partially offset by a rise within the permissible complete weight for trailers within the EU. The upper acquisition prices of the e-trailer are counteracted by decrease working prices,” BMW mentioned.
