To achieve emission reduction targets and to improve local air quality of cities, the uptake of Electric Freight Vehicles (EFV) is essential. Knowledge concerning why companies do adopt EFV is lacking. Research about the diffusion of innovations and the market of EFV shows that frontrunner companies with an innovative or early adopting mindset are adopting (or willing to adopt) EFV. Increase in demand of EFV by such companies can help take a step forward towards mass production of EFV and eventually reduction in purchase cost of EFV. The main objective of this paper is to get insights into the decision-making attributes of frontrunner companies. A qualitative approach was used and 14 interviews were conducted among frontrunner companies delivering goods in the city of Amsterdam. Results show that innovators and early adopters are all motivated by socially or environmentally positive effects of EFV. Strategic motives played a role for all companies who already adopted EFV. All companies wanted to adopt EFV but technical limitations, due specialrequirements for the goods transported, are a reason to not adopt EFV. Getting insights into the preferences of frontrunner companies, the (local) authorities can adjust their policy, schemes and sustainability campaigns to attract more companies adopting EFV. Manufacturing companies can use the insights from this research to adapt their vehicle technology to answer needs of the potential customer for faster adoption rate.
The mass adoption of Electric Vehicles (EVs) might raise pressure on the power system, especially during peak hours. Therefore, there is a need for delayed charging. However, to optimize the charging system, the progression of charging from an empty battery until a full battery of the EVs based on realworld data needs to be analyzed. Many researchers currently view this charging profile as a static load and ignore the actual charging behavior during the charging session. This study investigates how different factors influence the charging profile of individual EVs based on real-world data of charging sessionsin the Netherlands, enabling optimization analysis of EV smart charging schemes.
This paper explores current and potential future use of fast charging stations for electric passenger vehicles. The aim of the paper is to analyse current charging patterns at fast charging stations and the role of fast charging among different charging options. These patterns are explored along the lines of the technical capabilities of the vehicles and it is found that with increasing battery capacity the need for fast charging decreases. However, for those vehicles with large charging capacities there are indications that fast charging is perceived as more convenient as these are used more often. Such results indicate a larger share for fast charging if charging capacities increase in the future. Results from a spatial analysis show that most fast charging is done at a considerable distance from home, suggesting mostly ‘on the road’ charging sessions. Some fast charging sessions are relatively close to home, especially for those without private home charging access. This shows some future potential for fast charging in cities with many on-street parking facilities.
In september 2017 startten de lectoraten LEAN-World Class Performance en Automotive Research van de HAN University of Applied Sciences met het onderzoek ‘Werkplaats op Weg’ (cofinanciering door SIA middels het RAAK-MKB subsidieprogramma). Hierin werd de vraag beantwoord: “Wat betekenen alle technologische ontwikkelingen voor de gewenste inrichting van onze onderhoudsprocessen? Wat betekent dit voor acties die we nu en in de nabije toekomst moeten nemen?” De autowerkplaats van de toekomst zal - door innovaties in autotechnologieën, toenemende zorgen over het milieu en klimaat, en een veranderende toekomstvisie op mobiliteit - verschillen van huidige werkplaatsen. Deze ontwikkelingen leidden tot grote onzekerheid bij MKB-ondernemers, met name over de mogelijke effecten op de onderhoudsvraag van voertuigen. Werkplaats op Weg heeft het kennishiaat hieromtrent opgepakt. Op basis van specifieke casussen, interviews en praktijkonderzoeken zijn zes potentiële bedrijfstypes voor het MKB gedefinieerd. Deze zijn gelinkt aan de eerder beschreven technologische en maatschappelijke ontwikkelingen. De relevantste technologische ontwikkelingen die hierin centraal stonden zijn Connected, Autonomous, Shared en Electric Vehicles (CASE; zie figuur 1). De analyse heeft geleid tot concrete en toegankelijke aanbevelingen en online tools. Hiermee kunnen bedrijven binnen de sector hun eigen strategische keuzes maken met betrekking tot het uitvoeren en organiseren van werkzaamheden in hun werkplaats. Tevens is vastgesteld welke consequenties er zijn voor automotive opleidingen. Resultaten van het onderzoek zijn verzameld op de website: www.werkplaatsopweg.nl Figuur 1: Resultaten Werkplaats op Weg Met behulp van de Top-Up willen we onderzoeken hoe ondernemers, onderwijzers en onderzoekers om kunnen gaan met onverwachte, disruptieve veranderingen zoals de Coronacrisis, als aanvulling op de eerdere bevindingen die vooral gericht waren op het omgaan met verwachte technologische innovaties. Gezien de enorme en radicale impact van de huidige coronacrisis, is dit het perfecte moment om de sector extra aandacht en ondersteuning hiertoe aan te bieden.
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.
In the road transportation sector, CO2 emission target is set to reduce by at least 45% by 2030 as per the European Green Deal. Heavy Duty Vehicles contribute almost quarter of greenhouse gas emissions from road transport in Europe and drive majorly on fossil fuels. New emission restrictions creates a need for transition towards reduced emission targets. Also, increasing number of emission free zones within Europe, give rise to the need of hybridization within the truck and trailer community. Currently, in majority of the cases the trailer units do not possess any kind of drivetrain to support the truck. Trailers carry high loads, such that while accelerating, high power is needed. On the other hand, while braking the kinetic energy is lost, which otherwise could be recaptured. Thus, having a trailer with electric powertrain can support the truck during traction and can charge the battery during braking, helping in reducing the emissions and fuel consumption. Using the King-pin, the amount of support required by trailer can be determined, making it an independent trailer, thus requiring no modification on the truck. Given the heavy-duty environment in which the King-pin operates, the measurement design around it should be robust, compact and measure forces within certain accuracy level. Moreover, modification done to the King-pin is not apricated. These are also the challenges faced by V-Tron, a leading company in the field of services in mobility domain. The goal of this project is to design a smart King-pin, which is robust, compact and provides force component measurement within certain accuracy, to the independent e-trailer, without taking input from truck, and investigate the energy management system of the independent e-trailer to explore the charging options. As a result, this can help reduce the emissions and fuel consumption.
