Does experience matter? Assessing user motivations to accept a vehicle-to-grid charging tariff
Vehicle-to-grid (V2G) could be a cornerstone to ensure the efficient integration of a large number of electric vehicles (EVs) and the resulting electricity demand into the energy system. However, successful V2G adoption requires direct interaction with the EV user. To explore user preferences and requirements in the context of a V2G charging tariff, we conducted a survey (N = 1196). We assess usersâ minimum range requirements and willingness to pay for a V2G charging tariff and relate them to usersâ experience with EVs. By building a mediation model, we evaluate the importance of three charging strategies to guide usersâ minimum range requirements and expected monetary savings. The results reveal EV ownersâ preference for a climate-neutral charging strategy, leading to a higher readiness to accept lower minimum ranges and lower monetary savings. These results are especially important to aggregators, aiming to design profitable business models, while accounting for user requirements and preferences
A Techno-Economic Investigation of Advanced Vehicle Technologies and Their Impacts on Fuel Economy, Emissions, and the Future Fleet
A more sustainable transportation energy future for society is the principal motivation of this dissertation. The central purpose of this work is to investigate vehicle technologies that contribute to fuel and emissions reductions while preserving consumer choice, and to evaluate their technological performance and economic practicability as essential aspects of meeting aspirational targets and regulatory requirements associated with the future vehicle fleet
Why did Better Place fail?: Range anxiety, interpretive flexibility, and electric vehicle promotion in Denmark and Israel
With almost 500,000. Drawing from science and technology studies and the notion of âinterpretive flexibility,â this paper posits several reasons to explain the failure of Better Place, including that Denmark is not as âgreenâ as it seems nor is the Israeli market as attractive as believed, and that Better Place's solution to charging time and range anxiety resolved a psychological, not a functional, barrier of the general public to adopt electric vehicles. Before investigating these two reasons, the paper presents a short history of Better Place and explores the contours of its operations in Denmark and Israel. It then discusses why Better Place âfailedâ across both countries before concluding with implications for energy planning, policy, and analysis
Barriers to Electric Vehicle Adoption in Finland and How to Overcome them: An Analysis of Consumer Opinions and Perceptions
Objectives
The main objective of this study was to explore consumer opinions and perceptions regarding EVs and EV incentive policies in Finland in order to better understand how adoption rates could be increased.
Summary
A qualitative online survey was conducted within Finland with 71 respondents, most of which were Finnish students. Respondents were mainly asked to indicate their level of knowledge and experience with EVs, to rate different benefits and drawbacks of EVs, and to rate the appeal of different policy incentives for increasing EV adoption rates in Finland.
Conclusions
The results indicated that while aspects like high purchase price and range constraints are considered severe limitations for EV adoption, the most severe limitation currently is a lack of charging infrastructure in Finland. The results also highlight the need for consumer education regarding EVs in Finland as both OEMs and the government stand to benefit by better informing consumers
Modeling the uptake of plug-in vehicles in a heterogeneous car market using a consumer segmentation approach
There is broad agreement on the need for substantial use of low carbon vectors in the long term in the transport sector. Electrification, via mass market adoption of plug-in vehicles (i.e. battery electric and plug-in hybrid electric vehicles), has emerged as a front runner for road transport across the globe, but there are concerns that the pace and extent implied by many modelling studies is problematic and that assessment of (a) the heterogeneity in the market, (b) other low carbon vectors (e.g. conventional hybrids, hydrogen fuel cell) and (c) life cycle energy and environmental impacts have been relatively neglected. This paper aims to fill these gaps by examining the timing, scale and impacts of the uptake of plug-in vehicles in the heterogeneous UK car market from a consumer perspective. To achieve this aim it (a) brings together a bespoke disaggregated model of the transport-energy-environment system (the UK Transport Carbon Model) with previous work by the authors on heterogeneity in the demand for and supply of plug-in vehicles and (b) applies the improved model to develop future low carbon scenarios that assess the potential impact of different investment pathways and policy approaches to the electrification of cars with the view to meeting the UKâs legally binding carbon budgets to 2050. The results show the importance of accounting for the heterogeneity in and dynamic nature of the car market in terms of new technology adoption by private consumers, so called âuser choosersâ and fleet managers, as well as accounting for potential effects on wider life cycle emissions resulting from different uptake pathways. It allows an assessment of the effectiveness of different policy instruments, market conditions (vehicle supply, private vs fleet market, vehicle segments) and social factors (consumer awareness, range âanxietyâ, perceived charging requirements) on different consumer segments, thus providing more policy-focused conclusions on the likely pathways to high penetration of plug-in vehicles that may be required to meet future carbon and air quality targets
Maximizing Smart Charging of EVs: The Impact of Privacy and Money on Data Sharing
Smart charging has the potential to shift peak load to times of lower demand, which better exploits renewable generation and enhances grid resilience. For increased effectiveness, smart charging requires access to data that consumers might be hesitant to share. To explore which data consumers would share and which factors influence this decision, we adopt the Barth and de Jongâs risk-benefit calculation framework to smart charging and conduct an online-survey (n = 479). We find that most respondents who would share charging details with a smart charging application, are ambivalent about location data and would never share calendar details. When presented with concrete monetary rewards, participants lose their initial reservations and would share all data for an amount dependent on the dataâs sensitivity. Thus, our study contributes to research on the privacy paradox by highlighting the importance of calculations between perceived risks and benefits for the decision to share data

Understanding the socio-technical nexus of Nordic Electric Vehicle (EV) barriers: a qualitative discussion of range, price, charging and knowledge
Electric vehicles are perceived as a key alternate to internal combustion engine vehicles for a transition to a decarbonized society. However, this transition towards the electrification of transport has not made equal progress globally, and faced several impediments to consumer adoption of EVs across the Nordic region and beyond. While there has been a multitude of reasons provided in the literature, we aim to characterize the barriers that remain to electrification today, as well as their perceived interconnections and futures. To provide insight into this query, the authors conducted 227 semi-structured interviews with transportation and electricity experts from 201 institutions across seventeen cities in Denmark, Finland, Iceland, Norway, and Sweden. The qualitative results and consequent cluster analysis show that common barriers like range, price and charging infrastructure continue to persist, despite technological advancements over the recent years. At the same time, results also show that barriers are highly interconnected and are commonly connected to consumer knowledge and experience. The article concludes with a discussion of policy implications of the findings and potential future research

Navigating expert skepticism and consumer distrust: rethinking the barriers to vehicle-to-grid (V2G) in the Nordic region
Vehicle-to-grid (V2G) refers to a technology that could help make the electricity grid more effective, reduce the cost of ownership of electric vehicles (EVs), and help integrate intermittent renewable energy sources. However, despite these advantages, implementation and even knowledge of the technology is not widespread. In order to explore why, we ask the question: what are the barriers that V2G currently faces? To provide an answer, the authors conducted 227 semi-structured interviews with transportation and electricity experts from 201 institutions across seventeen cities within the a market currently experimenting with electric mobility and V2G, the Nordic region. Results show that there is an extensive range of barriers facing V2G, with experts suggesting in total 35 categories of barriers. While the literature espouses substantial benefits of V2G, the experts interviewed generally displayed skepticism of the benefits and necessity of V2G in the Nordics. We categorized the top nine discussed barriers into four clusters. These clusters focused on the expertsâ skepticism of the benefits of V2G, consumer acceptance, economic viability, and regulatory structure for V2G participation. We conclude the paper with policy implications and suggestions for future research
