Hamburg, Germany: Dachser is testing four battery-electric Krone refrigerated trailers with Carrier Transicold refrigeration in Germany. The trailers have a 23kWh battery and axle-driven generator. The battery is charged within three to four hours directly at loading and no extra charging infrastructure is required for the trailers with the generator providing energy for cooling.
When the truck travels at more than 20km/h, the generator axis supplies enough power to operate the refrigeration and charge the battery. The use of battery-electric refrigerated truck trailers not only improves the carbon footprint of food transportation, they also cause significantly less noise than diesel refrigeration units. Various test scenarios are being played at the three depots, starting with the use of the trailer in the shuttle service and on local journeys, up to long-distance routes, for example from Langenau to Hamburg.
“Together with our long-standing trailer partners, Krone and Carrier Transicold (refrigeration unit), we are deliberately taking the step of testing new technologies in live operation. We have been doing this successfully for many years with our towing units,” said Christian Schütz, department head technics/technical purchase, Dachser.
“In the future, we want to deploy even more of these units to support our climate protection goals. In addition to the operational issues when deploying them in our branches, also economic factors play a special role for the purchase and maintenance of these trailers, which we will verify in detail in test operations.”
