Modelling a capacity-constrained public charging infrastructure network for electric trucks in Germany

CO2 emission standards in the European Union necessitate the introduction of zero-emission trucks. Battery electric trucks are one promising alternative to diesel trucks. However, a public fast charging infrastructure is necessary for operation. Existing charging infrastructure models do not contain restrictions regarding the maximum size of a single charging location, leading to unrealistically large locations. Here, we integrated a capacity constraint derived from the available parking lots and applied the resulting model to 236,000 origin-destination traffic flows. Considering a vehicle range of 300 km, we identified 124 optimal charging locations with approximately 12,000 charging points in Germany. Hence, our locations are still quite large, but feasible from the perspective of available parking space. Without the capacity constraint, 42 charging locations could serve Germany.
