A Proposal for a Novel Technical Approach for Smart Sharing of Private Charging Stations

In Germany, a shortage of public charging stations for the significantly increasing number of electric cars exists. This shortage, along with the associated range anxiety, poses a hurdle for the market entry of electric cars. In addition, the construction of public charging stations for electric vehicles is outside the control of vehicle owners. Accelerating this process is challenging due to regulatory and other considerations. This paper presents a novel scientific and technical approach to complement existing public charging infrastructure by integrating privately owned charging stations into a publicly accessible ecosystem. The core of our work explores the integration of private charging stations into the application ecosystem, clarifying the reservation process and addressing potential challenges. Furthermore, we provide a comprehensive overview of the features related to routing and locating near charging stations. We examine the potential challenges that may arise during the practical implementation of the proposed system. The technical feasibility of the approach is validated through implementation and simulation, demonstrating the practical applicability of the proposed system and its ability to support real-world usage scenarios. The results indicate that such a system has significant potential to enhance the accessibility and usability of charging infrastructure, thereby promoting sustainable mobility and lowering the entry barriers for electric vehicles. By providing integrated charging information, reservation functionality, and route planning, the proposed solution contributes to increasing user acceptance and supporting the transition toward more environmentally friendly transportation.
