“…The first part of the analysis involves modelling the effect of placing different sizes of static chargers along existing freight routes and calculating the battery sizes required. This is done using a drive cycle generator and a vehicle model [12].…”

“…The drive cycle synthesiser used here, developed in [12], uses the origin, destination and rest stops to generate a route for the vehicle using 'HERE Maps'. It then overlays the specified charger locations and charger capacities on the route to generate the desired drive cycle and a 'charging signal' containing charging powers and times.…”

“…The vehicle model, detailed in [12], is based on a battery electric bus model developed in [13] and validated in [6]. The model was scaled to fit a 44-tonne electric HGV with electric road systems (ERS) and static charging in [12] and validated using data from Siemens and Scania. The vehicle model includes auxiliary loads such as refrigeration [14].…”

Electric heavy goods vehicles (HGVs) are a key step towards reducing road freight emissions. However, they require large batteries and fast chargers. There is interest in exploring high-capacity chargers at warehouse docks that can charge at a rate of 1 MW. These chargers are expensive and complex but are needed to run big-battery electric HGVs without a change in logistics operations. Hence, this paper aims at evaluating scenarios in which high-capacity chargers are useful by estimating battery sizes required for various logistics operations. The paper also aims to evaluate the circumstances under which high-capacity chargers are economically feasible using a 15-year cost break-even model. It is seen that highcapacity chargers are useful and economically feasible for journeys with smaller stop durations and longer distances, but not for journeys with longer stops. It is also observed that they need to be supplemented by different charging strategies and dynamic charging techniques.

“…Significant research demonstrating the capability of this technology for economical freight transportation using electric HGVs has been going on in Germany, and Sweden [19], [20]. This technique has been studied for its feasibility in the UK highways too [21], [22]. In the current study, the feasibility of HGV electrification through overhead catenary lines has been analysed closely with the support of a detailed physics-based model of heavy vehicles.…”

Even though diesel-powered Heavy Goods Vehicles (HGVs) are major contributors of greenhouse gas emission, HGV electrification is still in its infancy owing to various challenges. Costlier and heavier batteries and lack of charging infrastructure along long routes are the major bottlenecks in the realisation of HGV electrification for long-haul freight transportation. In this regard, adopting technologies that can make HGV electrification viable is vital to aid the transportation sector decarbonisation. Benefiting from approaches such as the use of overhead catenary power, and conforming to operate in a platoon formation, it would be possible to considerably reduce the cost of HGV electrification and make it economically feasible. Utilising overhead catenary infrastructure would result in requiring economical charging infrastructure, shorter charging cycles, and smaller batteries, while not compromising on the overall payload of HGVs. HGVs in platoon formation result in energy consumption reduction and increased traffic throughput. This paper investigates the benefits of using overhead catenary-powered electric HGVs for freight transportation and also explores the advantages associated with electric HGV platoon formations on the same. The feasibility analysis has been done with the support of close to real physics-based electric HGV models on realistic operating scenarios adopting an in-service highway drive cycle. From the analysis, electric HGV platooning using overhead catenary as the power source was found to be economical with ≈ 10.4% reduction in electricity cost when compared to without platooning while devising electrification strategies for long-haul freight transportation.

“…Cost is the primary factor driving selection of freight solutions 5,6 and prior research has demonstrated that ERS can bring systemic cost savings. This is because destinations can be reached with smaller battery packs than if electric vehicles are charged statically, reducing vehicle cost [7][8][9][10][11] and raising cargo capacity. However, due to strong economies of scale and scope 8,9 , the infrastructure itself can only be cost competitive at high participation by tra c, which further requires extensive -likely international -ERS buildout.…”

This study addresses the pressing issue of reducing greenhouse gas (GHG) emissions in the road freight sector. We investigate whether Electric Road Systems (ERS) for heavy duty trucks are a viable solution for the European Union to align the sector with economy-wide GHG reduction targets. Results are based on simulations in MOSTACHI, a new model for studying interaction effects between competing charging infrastructure and cost-minimizing vehicle operators. ERS impact is assessed on transport cost, GHG emissions, resource demand, and competing charging infrastructure. We find that for ERS to be a no-regret investment, an accompanying policy is needed that penalizes non-participation. This ensures the economies of scale necessary for the ERS infrastructure’s viability and reduces transport cost on average. With policy, ERS increases battery-electric truck uptake and GHG reductions and reduces demand for batteries and fossil and renewable fuels, throughout the infrastructure lifetime.
