“…However, the transition to EVs as a viable solution for reducing greenhouse gas emissions in the transportation sector presents several challenges for the power sector (Khan et al, 2022;Zhang et al, 2022). For example, at the power system level, accommodating the increased demand necessitates additional power plants to cater to EVs' energy needs and serve as reserves (Heuberger et al, 2020).…”

Demand management of electric vehicles (EVs) in shared residential parking lots presents challenges for sustainable transportation systems. Especially, in shared parking lots where multiple EVs share the same parking space, such as residential apartments. This is challenging due to involvement of various factors such as limited number of chargers, limited capacity of transformer, and diverse driving behavior of EV owners. To address this issue, this study proposes an optimal demand management framework that addresses limited chargers, transformer capacity, and diverse driving behavior to promote sustainable EV integration. By estimating driving behavior, energy consumption, and utilizing a linear programming-based optimization model, power allocation to EVs is optimized based on multiple factors. A satisfaction index is introduced to measure the satisfaction level of the EV community, further emphasizing user-centric sustainability. Performance analysis includes factors such as power usage, charger utilization, and community satisfaction. The performance of the proposed method is compared with a conventional method and the proposed method increase the satisfaction index of the community by up to 10%. In addition, sensitivity analysis is used to explore the impact of factors like charger availability, EV penetration, and transformer capacity limits. Results show that with 3% EV penetration, satisfaction levels exceed 75%, reaching over 80% with five chargers and 6% EV penetration.

“…A growing body of research has identified positive and negative unintended consequences of the large-scale transition from gas to battery electric vehicles (BEVs).Beyond decarbonization, BEVs have the potential to positively impact air quality and environmental justice [1][2][3][4][5][6] and to provide quality-of-life improvements through Vehicle-to-grid (V2G) technologies as vehicles can be used to power homes during outages 7,8 . However, there are growing questions about BEV carbon efficiency 9, 10 and mass-production feasibility [11][12][13][14][15] and BEVs also introduce challenges for integration into the grid 16 , create infrastructure vulnerabilities 17 and ties between efficiency and consumer behavior 18 .BEVs also pose a challenge to owners during natural disasters 19,20 . Electric vehicles couple transportation and electric power systems and this link poses a risk of power outages making transportation unavailable during disasters and limiting mobility for BEV owners during power outages.…”

Electric vehicles (EVs) link mobility and electric power availability, posing a risk of making transportation unavailable during blackouts. We develop a computational framework to quantify the impact of EVs on mobility and access to services and find that existing access issues are exacerbated by EVs. Our results demonstrate that larger batteries reduce mobility constraints but their effectiveness is dependent on the geographic distribution of services and households. We explore the trade-offs between mobility and quality-of-life improvements presented by Vehicle-to-Grid technologies and the feasibility and trade-offs of public charging infrastructure as a solution to access inequalities. Equitable access to essential services (e.g. supermarkets, schools, parks, etc.) is the most important aspect of community resilience and our results show vehicle electrification can hinder access to essential services unless properly incorporated into policy and city-scale decision-making.

Modern power and transportation systems are subject to high requirements for reliability and performance in performing their specified functions. At the same time, these requirements are constantly increasing with the increasing complexity of technology and the introduction of electronics and computer technology into its structure. This is fully applicable to energy and transportation infrastructure, including electric vehicles. The complexity of the systems and increasing requirements for them have led to the fact that the problem of increasing their operational reliability has acquired great importance. The article presents a review of methods and justification of ensuring a high level of reliability and serviceability of technical systems as one of the most important tasks in the creation and operation of complex systems, such as modern energy and transportation systems. It is shown that a significant reserve in solving the problem of increasing the reliability and performance of technical systems is the information on failures and malfunctions of these systems obtained from the field of operation. The methodology of collection and processing of statistical information on failures of vehicles described by different distribution laws is outlined.
