Charging an electric vehicle needs to be as simple as possible for the user. He needs to park his car, plug his vehicle and identify to start charging. There is no need to understand the technology and protocols needed to reach this simple task.For the students and researchers of the Amsterdam University of Applied Science (AUAS / HvA), there is a need to understand as deep as possible all the techniques involved in this technology.The purpose of this document is to give to the reader the information he needs to understand how an electric car can be charged and how he can use these knowledges to analyses and interpret data.
Electric vehicles and renewable energy sources are collectively being developed as a synergetic implementation for smart grids. In this context, smart charging of electric vehicles and vehicle-to-grid technologies are seen as a way forward to achieve economic, technical and environmental benefits. The implementation of these technologies requires the cooperation of the end-electricity user, the electric vehicle owner, the system operator and policy makers. These stakeholders pursue different and sometime conflicting objectives. In this paper, the concept of multi-objective-techno-economic-environmental optimisation is proposed for scheduling electric vehicle charging/discharging. End user energy cost, battery degradation, grid interaction and CO2 emissions in the home micro-grid context are modelled and concurrently optimised for the first time while providing frequency regulation. The results from three case studies show that the proposed method reduces the energy cost, battery degradation, CO2 emissions and grid utilisation by 88.2%, 67%, 34% and 90% respectively, when compared to uncontrolled electric vehicle charging. Furthermore, with multiple optimal solutions, in order to achieve a 41.8% improvement in grid utilisation, the system operator needs to compensate the end electricity user and the electric vehicle owner for their incurred benefit loss of 27.34% and 9.7% respectively, to stimulate participation in energy services.
Electric vehicles have penetrated the Dutch market, which increases the potential for decreased local emissions, the use and storage of sustainable energy, and the roll-out and use of electric car-sharing business models. This development also raises new potential issues such as increased electricity demand, a lack of social acceptance, and infrastructural challenges in the built environment. Relevant stakeholders, such as policymakers and service providers, need to align their values and prioritize these aspects. Our study investigates the prioritization of 11 Dutch decision-makers in the field of public electric vehicle charging. These decision-makers prioritized different indicators related to measurements (e.g., EV adoption rates or charge point profitability), organization (such as fast- or smart-charging), and developments (e.g., the development of mobility-service markets) using the best-worst method. The indicators within these categories were prioritized for three different scenario's in time. The results reveal that priorities will shift from EV adoption and roll-out of infrastructure to managing peak demand, using more sustainable charging techniques (such as V2G), and using sustainable energy towards 2030. Technological advancements and autonomous charging techniques will become more relevant in a later time period, around 2040. Environmental indicators (e.g., local emissions) were consistently valued low, whereas mobility indicators were valued differently across participants, indicating a lack of consensus. Smart charging was consistently valued higher than other charging techniques, independent of time period. The results also revealed that there are some distinct differences between the priorities of policymakers and service providers. Having a systematic overview of what aspects matter supports the policy discussion around EVs in the built environment.
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.
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.
