The transition from diesel-driven urban freight transport towards more electric urban freight transport turns out to be challenging in practice. A major concern for transport operators is how to find a reliable charging strategy for a larger electric vehicle fleet that provides flexibility based on different daily mission profiles within that fleet, while also minimizing costs. This contribution assesses the trade-off between a large battery pack and opportunity charging with regard to costs and operational constraints. Based on a case study with 39 electric freight vehicles that have been used by a parcel delivery company and a courier company in daily operations for over a year, various scenarios have been analyzed by means of a TCO analysis. Although a large battery allows for more flexibility in planning, opportunity charging can provide a feasible alternative, especially in the case of varying mission profiles. Additional personnel costs during opportunity charging can be avoided as much as possible by a well-integrated charging strategy, which can be realized by a reservation system that minimizes the risk of occupied charging stations and a dense network of charging stations.

The number of light commercial vehicles (LCV) in cities is growing, which puts increasing pressure on the livability of cities. Freight vehicles are large contributors to polluting air and CO2 emissions and generate problems in terms of safety, noise and loss of public space. Small electric freight vehicles and cargo bikes can offer a solution, as they take less space, can maneuver easily and do not emit local pollution. There is an increasing interest in these vehicle, called light electric freight vehicles (LEFV’s), among logistic service providers in European cities. However, various technical and operational challenges impede large scale implementation. Within the two-year LEVV-LOGIC project, (2016-2018) the use of LEFV’s for city logistics is explored. The project combines expertise on logistics, vehicle design, charging infrastructure and business modelling to find the optimal concept in which LEFV’s can be a financial competitive alternative for conventional freight vehicles. This contribution to EVS30 will present the project’s first year results, showing the guideline for and the applied design of LEFV for future urban city logistics.

This paper presents guidelines for the design of LEFV based on the standardized rolling container (length 800 mm, width 640 mm, height 1600 mm) and for the charging infrastructure.
To reach the European Green Deal by 2050, the target for the road transport sector is set at 30% less CO2 emissions by 2030. Given the fact that heavy-duty commercial vehicles throughout Europe are driven nowadays almost exclusively on fossil fuels it is obvious that transition towards reduced emission targets needs to happen seamlessly by hybridization of the existing fleet, with a continuously increasing share of Zero Emission vehicle units. At present, trailing units such as semitrailers do not possess any form of powertrain, being a missed opportunity. By introduction of electrically driven axles into these units the fuel consumption as well as amount of emissions may be reduced substantially while part of the propulsion forces is being supplied on emission-free basis. Furthermore, the electrification of trailing units enables partial recuperation of kinetic energy while braking. Nevertheless, a number of challenges still exist preventing swift integration of these vehicles to daily operation. One of the dominating ones is the intelligent control of the e-axle so it delivers right amount of propulsion/braking power at the right time without receiving detailed information from the towing vehicle (such as e.g. driver control, engine speed, engine torque, or brake pressure, …etc.). This is required mainly to ensure interoperability of e-Trailers in the fleets, which is a must in the logistics nowadays. Therefore the main mission of CHANGE is to generate a chain of knowledge in developing and implementing data driven AI-based applications enabling SMEs of the Dutch trailer industry to contribute to seamless energetic transition towards zero emission road freight transport. In specific, CHANGE will employ e-Trailers (trailers with electrically driven axle(s) enabling energy recuperation) connected to conventional hauling units as well as trailers for high volume and extreme payload as focal platforms (demonstrators) for deployment of these applications.
Tegen de achtergrond van de klimaatbescherming worden de eisen aan de stadscentra steeds hoger. Logistiek in steden heeft een grote invloed op de vermindering van emissies. Koeriers-, expres- en pakketzendingen vertegenwoordigen reeds een groot en toenemend deel van de goederenleveringen in steden. Ook de vraag van klanten naar klimaatneutrale pakketdiensten neemt toe. Om de daaruit voortvloeiende stijgende kosten, het toegenomen verkeersvolume en de lasten in termen van landgebruik en lucht- en geluidsemissies tegen te gaan, zijn nieuwe logistieke concepten nodig, met namein de context van de zogenaamde "last mile". Decentralisatie, zelfvoorziening op energiegebied en flexibiliteit in de tijd zijn beslissende sleutels tot kosten- en energieoptimalisatie.Het doel van het project is dan ook de ontwikkeling van een innovatief, intelligent en duurzaam distributiesysteem, bestaande uit een energetisch zelfvoorzienende, mobiele mini-hub en een voor dit doel ontworpen en nieuw ontwikkeld elektrisch voertuig. - LEFV (Light Electric Freight Vehicle), dat werkt op basis van de hernieuwbare energie die door de mini-hub wordt opgewekt. De mini-hub is modulair en gemaakt van duurzame bouwmaterialen en is ook geschikt voor tijdelijk gebruik.
Road freight transport contributes to 75% of the global logistics CO2 emissions. Various European initiatives are calling for a drastic cut-down of CO2 emissions in this sector [1]. This requires advanced and very expensive technological innovations; i.e. re-design of vehicle units, hybridization of powertrains and autonomous vehicle technology. One particular innovation that aims to solve this problem is multi-articulated vehicles (road-trains). They have a smaller footprint and better efficiency of transport than traditional transport vehicles like trucks. In line with the missions for Energy Transition and Sustainability [2], road-trains can have zero-emission powertrains leading to clean and sustainable urban mobility of people and goods. However, multiple articulations in a vehicle pose a problem of reversing the vehicle. Since it is extremely difficult to predict the sideways movement of the vehicle combination while reversing, no driver can master this process. This is also the problem faced by the drivers of TRENS Solar Train’s vehicle, which is a multi-articulated modular electric road vehicle. It can be used for transporting cargo as well as passengers in tight environments, making it suitable for operation in urban areas. This project aims to develop a reverse assist system to help drivers reverse multi-articulated vehicles like the TRENS Solar Train, enabling them to maneuver backward when the need arises in its operations, safely and predictably. This will subsequently provide multi-articulated vehicle users with a sustainable and economically viable option for the transport of cargo and passengers with unrestricted maneuverability resulting in better application and adding to the innovation in sustainable road transport.
