Electrification potential of an existing heavy duty vehicle fleet – a techno-economic analysis
This work determines the techno-economic potential of electrifying the truck fleet of the “Badische Staatsbrauerei Rothaus AG”, based on the analysis of data containing two weeks of vehicle operation. The analysis reveals that overnight depot charging maximises potential, while daytime charging allows for longer tours using vehicles with smaller batteries. Economically, electrification of this fleet is beneficial, paying off within a few years as higher operation costs of the diesel fleet offset the high purchase price of electric trucks. Financial advantages increase with consistent usage and longer vehicle service life, supported by lower depot electricity prices. Sensitivity analysis shows that fuel prices, vehicle costs, and residual values of electric trucks significantly influence results, while charging infrastructure costs have less influence on the outcome. This study emphasises the feasibility and profitability of the electrification of truck fleets, identifies the most important influencing factors, and thus provides a basis for the targeted improvement of framework conditions.
