The global shift to electric vehicles (EVs) necessitates strategic deployment of public charging infrastructure to meet growing demand. Our study focuses on Prague, Czechia, analyzing real-world data to understand EV charging demand. Utilizing charging session and geospatial data, we categorize charging points by urban context and assess factors influencing demand. Geospatial analysis helps identify potential charging sites based on accessibility, location, and population density. Insights from temporal demand variations, share of charging instances per area type, and load profile characteristics guide infrastructure planning. Despite limitations in data scope and geographical specificity, this study offers valuable insights into public charging behavior, laying groundwork for future enhancements and predictive modeling to inform efficient charger placement in urban EV infrastructure.

Electric vehicles (EVs), as facilitators of grid stability and flexibility, provide a critical solution to the energy infrastructure's evolving demands, underscored by the growing integration of renewable energy sources (RES) and the rapid increase in EV adoption worldwide. This trend is particularly evident in Europe which is experiencing dramatic increases in both the adoption of RES and EVs. Vehicle-to-grid (V2G) technology allows EVs to operate as a two-way power flow to both draw and feed electricity into the grid. This multidisciplinary overview examines the role of V2G systems in enhancing grid performance, identifying corporate vehicle fleets as key flexibility providers, and integration with Smart Grid technologies as a key element for successful V2G implementation. In a scoping analysis of recent literature (2005–2024), we identify challenges such as privacy, security, and regulatory compliance as well as a critical gap in establishing economically sustainable models for aggregators, distribution system operators (DSOs), generation companies (GENCOs), and end-users. Drawing from these insights, we then discuss the necessity for future research to develop models that ensure equitable benefits across stakeholders and the importance of models that can adapt to country-specific mechanisms. The findings from our overview argue that the integration of EVs, V2G, and RES are essential components for developing future energy systems that are resilient, adaptable, decarbonized, and sustainable.

This study addresses the challenge of predicting electric vehicle (EV) charging profiles in urban locations with limited data. Utilizing a neural network architecture, we aim to uncover latent charging profiles influenced by spatio-temporal factors. Our model focuses on peak power demand and daily load shapes, providing insights into charging behavior. Our results indicate significant impacts from the type of Basic Administrative Units on predicted load curves, which contributes to the understanding and optimization of EV charging infrastructure in urban settings and allows Distribution System Operators (DSO) to more efficiently plan EV charging infrastructure expansion.

The transition to a sustainable energy system is critically dependent on the integration of renewable energy sources (RES) and the enhancement of grid stability. Electric vehicles (EVs) stand at the confluence of this transformation, not only revolutionizing transportation but also serving as a dynamic component in stabilizing and flexing the electricity grid. This contribution offers a brief overview of Vehicle-to-Grid (V2G) technology, outlining its significance in the evolving energy landscape. By summarizing the current state of the art, methodology, and the basic principles underlying V2G, the synopsis highlights how EVs can support grid stability and flexibility. It touches upon the historical context of V2G development to underscore the technology's potential and challenges. In essence, this overview aims to elucidate V2G's role in fostering a more resilient and sustainable energy future, emphasizing its importance in grid development.

The impact of the European Union’s carbon footprint reduction targets and their effects on the transport sector can be seen in the gradual trend towards replacing the combustion engine vehicles fleet with plug-in hybrid or fully electric vehicles. With the rapid growth of electric vehicles, many questions and issues arise associated with EV charging. The key to sustaining this rapid fleet renewal is constructing a dense public charging station network. This research aims to assist stakeholders and EV charging infrastructure developers in planning the strategic deployment of public charging stations in terms of number, charging power, and their placement in strategic locations in a city.
