This study developed a multi-day electric truck trip cost model to analyse cost-minimising carrier use of stationary charging, battery swapping and catenary electric roads in the EU TEN-T road network setting. Each of these three charging options has its own advantages for carriers, thus motivating the analysis. The multi-day truck segment accounts for almost one-fifth of all truck tonne kilometres within the EU, making it important to consider in the quest to decarbonise this sector. Nevertheless, this segment has until now been sparsely analysed in the literature on truck electrification. Based on the scenario analysis, the carrier truck trip costs in the current state (year 2024) and future state (year 2035) was analysed. The current state analysis revealed that catenary electric roads are a cost-minimising option to carriers, whereas future state analysis revealed that catenary electric roads and swapping can perform on par while being cost-advantageous vis-à-vis stationary charging. The sensitivity of these findings to battery parameters, electric road user charges, swapping fee levels and charging alliances was reported. The implications of the findings for carriers, vehicle producers and policymakers were discussed.
