Simulation-Based Comparative Assessment of a Multi-Speed Transmission for an E-Retrofitted Heavy-Duty Truck

Electric retrofitting (e-retrofitting) is a viable option for accelerating the renewal of heavy-duty vehicle fleets to reduce related emissions. We introduce simulation-based assessment e-retrofitting strategies vehicles. Our simulation tool, an electric fleet toolbox, comprises three modules, namely driving cycles, dynamics, and profiles. The first allows creation realistic cycles based on GPS data from real routes. dynamics profiles incorporate, e.g., modelling powertrain conditions. Ten were created used investigating comparing different alternatives, including original diesel powertrain, with single-speed transmission multi-speed transmission. vehicles simulated in two heavy-load scenarios. First, cargo load represented by maximum weight second, snow ploughing. found that truck significantly improved its traction performance gradeability. On other hand, effect efficiency, thereby energy consumption, remained rather minor. Considering given workload scenarios, our results advocate employing than omitting gearbox e-retrofit process.
