Purpose
The aim of this paper is to provide insight into how people assess different charging options in the context of electric mobility and how charging can be integrated into daily activities. The central research question concerns the acceptance of fast charging with direct current up to 200 kWh relative to alternative charging concepts such as...

... The German government has adopted a package of measures to support the development of electromobility by promoting measures and research to overcome problems that BEVs can bring (BMWi, 2017). High initial costs (Lim, Mak, & Rong, 2015;Mock & Yang, 2014) and range issues (Daubitz & Kawgan-Kagan, 2015; are frequently cited problems. From a transport planning perspective, carsharing in urban areas implementing battery electric vehicles (e-carsharing) offers a promising solution to these issues (Kumar & Bierlaire, 2012;Wappelhorst, Graff, Steiner, & Hinkeldein, 2013): It offers e-mobility without the initial costs in urban PART A: 1.2 The phenomenon of male users of innovative sustainable mobility 2 areas for typically short trips. ...
The research reveals that urban women's mobility needs are complex due to their involvement in household tasks and work-related travel, resulting in frequent but shorter trips. Despite these needs, current FFECS users are predominantly male, highlighting a gender disparity in the adoption of sustainable mobility solutions. The literature suggests that women's pragmatic view of cars could favour the uptake of shared electric mobility.
This mixed-methods research explores urban women's preferences for innovative mobility solutions, specifically focusing on free-floating electric carsharing (FFECS). The study investigates the motivations behind urban women's usage of FFECS and identifies measures to address potential barriers.
This dissertation adopts a mixed-method approach, integrating qualitative and quantitative research to examine how urban women can be effectively targeted for multimodal and intermodal mobility services. The research comprises three empirical stages:
1. Analysing a sample of early female adopters of e-carsharing in Berlin to understand their characteristics compared to male early adopters.
2. Extending this characterization to a representative sample of urban dwellers in Germany to explore gender differences in mobility access, perceptions, and attitudes, particularly towards sustainable transport.
3. Employing qualitative interviews and GPS-tracking to investigate gender-specific preferences and the practicality of e-carsharing for women.
Findings indicate distinct acceptance levels and attitudes among women regarding mobility. Four social constructs were identified that impede women's adoption of FFECS, providing a basis for recommendations aimed at enhancing service models and policies to better cater to urban women's mobility needs.
... Der subjektive Mehrwert könnte in der Nachhaltigkeit oder der Alltagserleichterung liegen, indem Nutzern von Elektroautos der Weg zur Tankstelle erspart bleibt [20]. Die Integration des Ladevorgangs in den Alltag ist ein Schlüsselfaktor für den Erfolg der E-Mobilität [23]. Der größte Vorteil, das Elektroauto über Nacht zu Hause laden zu können, besteht insbesondere in ländlichen Regionen, weil die meisten Haushalte über einen eigenen Stellplatz verfügen. ...
... This can, and will be, a challenge, as recent research has demonstrated that EV users have a different mindset toward "recharging" their vehicle, as opposed to "refueling" it (Daubitz & Kawgan-Kagan, 2014). On one hand, Philipsen et al. (2016), among others, claim that "limited charging options… contribute to the so-called range anxiety." ...
Research relating to electric vehicle (EV) charging is still in its early stage, as only the last 10 years have brought significant development. Particularly, there is a need for realistic representation of charging behavior. This empirical study gathered and analyzed "real-world" public charging data from a prominent European charging network owner and operator. The researchers demonstrated a clustering method used to analyze the charging behavior of users in an urban environment, using Berlin as a reference. Furthermore, linear regression analyses regarding the utilization of charging stations were performed to verify a pair of locational factors that were correlated with the utilization of certain stations. Key findings from the study included: a high number of users and a very high number of charge events from users in the identified "Car-Sharing" cluster; a significant number of users and charge events from users in the "At Home Chargers" cluster; a comparable number of charge events performed by users in the "Work Chargers" and "Private Roamers" clusters; and, within certain clusters, statistically significant results for linear regressions on station utilization, using points-of-interest within 300 meters as well as employment level in the area as regressors. Through this investigation, we intended to support all associated parties with the development of public charging infrastructure and to contribute a foundation for further studies regarding the public charging behavior of EV users.
This chapter presents a comprehensive review of the integration of renewable energy sources (RES) into electric vehicle (EV) charging infrastructure, addressing the critical challenges of carbon emissions reduction and reducing dependence on fossil fuels in the transportation sector. It begins with an overview of RES, including their types, characteristics, and current utilization in the energy sector. Subsequently, the chapter delves into the intricacies of EV charging infrastructure, discussing various station types and associated challenges. It then explores the integration of RES into EV charging systems, highlighting the benefits such as emissions reduction and considerations like grid stability. Technological advancements and case studies are presented to illustrate successful implementations of RES-EV charging systems. Additionally, the chapter examines the challenges and opportunities in this domain, including technical solutions, economic viability, policy frameworks, and grid integration strategies. Furthermore, future trends and research directions are discussed to promote sustainability and resilience in the transportation sector. The chapter underscores the significance of RES-EV integration in achieving environmental goals and concludes with recommendations for stakeholders and policymakers to advance this integration further.
Private charging infrastructure is critical to the diffusion of electric vehicles. However, as with all technologies, user acceptance is of primary importance here. This paper analyzes this acceptance with an empirical study with 488 participants. For this, a context-specific technology acceptance model including 9 hypotheses is developed. To validate the hypotheses, an online survey is designed for the German market. Results deliver insights on the general opinion on electromobility and private charging infrastructure and determine the factors influencing the acceptance behavior of potential users with regard to private charging infrastructure. Regarding the general opinion, most of the survey participants show a positive attitude. Regarding the factors, some, such as perceived effort and perceived usefulness, have an influence on the acceptance, while other factors, such as visual design and perceived cost, don’t.KeywordsElectric vehiclesPrivate charging infrastructureUser acceptance
