Overview

This dissertation investigates and provides comprehensive insights into three key areas of electric vehicle charging infrastructure optimization, the integration of recuperated braking energy from trains into electric vehicle charging stations, and the influence of transaction costs on the implementation and operation of electric vehicle charging infrastructure. The study aims to address the following research questions: (1) How can electric vehicle charging points be optimized for efficient use while maintaining cost-effectiveness? (2) How can the incorporation of recuperated braking energy from trains into electric vehicle charging stations impact their energy consumption and operating costs? (3) How do transaction costs affect the implementation and operation of electric vehicle charging stations, and how can they be reduced?To optimize electric vehicle charging points, the research reveals several effective strategies. Firstly, leveraging existing parking lots equipped with low-power chargers during off-peak hours, when they are underutilized, proves to be a viable approach. By reserving parking spaces in these lots, electric vehicle owners without private garages or chargers can access charging facilities, maximizing the potential of existing substations. Power dividing between individual charging stations and deferred charging functions are proposed to balance the load on local substations and mitigate peak demand. Integration of battery storage is explored as a solution to enhance stability and support both the local substation and the broader power grid. Additionally, the research highlights the importance of installing a sufficient number of AC (Alternating Current) chargers in urban and suburban areas, rather than focusing solely on the higher charging power of DC (Direct Current) chargers, based on real-world data analysis. Quantity over higher power output is emphasized when expanding charging facilities in public parking lots.The incorporation of recuperated braking energy from trains into electric vehicle charging stations is investigated as a means to improve energy efficiency and reduce the strain on the distribution grid. By capturing and utilising reclaimed brake energy and using it to charge electric vehicles, it helps to minimise energy waste and reduce the load on the electricity grid. Storage of excess recuperated braking energy in battery or capacitor energy storage systems and implementing charging power management functions at individual stations are identified as effective strategies. The study also reveals that companies responsible for powering train lines have an economic opportunity to sell recuperated braking energy for electric vehicle charging at a significantly higher value compared to selling it back to the grid. This presents a potential revenue boost for the company while potentially offering electric vehicle owners lower per kWh prices.Transaction costs are recognized as crucial factors influencing the successful implementation of electric vehicle charging stations, and more generally sustainable mobility. Contrary to common assumptions, the research finds that transaction costs tend to increase over time due to changes in programme administration, internal programme conditions, and information loss. To mitigate the impact of transaction costs, the dissertation proposes various strategies. Streamlining programme administration processes, improving information management systems, fostering collaboration and knowledge sharing among stakeholders, and implementing standardized procedures for infrastructure development are identified as effective approaches.The findings of this dissertation provide valuable insights and practical solutions for optimizing electric vehicle charging infrastructure, incorporating recuperated braking energy, and reducing transaction costs. The research contributes to the development of efficient and sustainable electric vehicle charging systems, facilitating the transition to cleaner transportation and supporting global efforts in mitigating climate change.
