EVOSS

The EVOSS project successfully demonstrated the transformative potential of the Robotic Charging Device (RCD) in revolutionising urban electric vehicle (EV) charging infrastructure. Through rigorous pilot programs in Tel Aviv and Thessaloniki, the project garnered invaluable insights into the RCD's performance capabilities and its effectiveness as a viable solution for the unique challenges of EV charging within urban environments. These pilots have served as crucial real-world testbeds, allowing for the evaluation of the RCD under diverse operational conditions and providing a strong foundation for future development.

In the Tel Aviv pilot, the energy efficiency of Thomas was a key focus. On average, the robot delivered 53.41 kWh of energy to vehicles for every 80 kWh deployed into its system, resulting in an overall energy efficiency of approximately 70%. While this efficiency level is not ideal, it is important to note that further iterations of the technology are expected to improve this metric significantly. The average charging speed of the robot was calculated to be 12.5 kW per hour, which is competitive with traditional charging infrastructure and demonstrates the potential of the robotic solution to meet the needs of urban EV users. In terms of time efficiency, the robot operated for an average of seven hours per day, with 65% of this time spent charging itself and the remaining 35% dedicated to charging vehicles. Despite these limitations, Thomas was able to charge two to three vehicles to their maximum capacity during each operational day. This performance is notable given the constraints of the pilot and highlights the potential of the robotic solution to outperform traditional fixed charging stations in similar conditions.

The results from the Thessaloniki pilot highlighted significant progress in several key performance areas. Notably, the pilot achieved an average of 110.49 kWh deployed per day. This figure represents an increase in energy delivery when compared to the Tel Aviv pilot, demonstrating the effectiveness of the improvements made to energy efficiency and the RCD's enhanced ability to perform more energy-demanding charging sessions in a shorter amount of time. One of the main factors that led to this enhanced energy deployment is the huge increase in charging speed that the RCD demonstrated. The pilot recorded a higher deploy speed of 45.36 kW, which is nearly double the speed that was recorded in Tel Aviv. This acceleration in charging capability translates directly to increased user convenience and a significant reduction in waiting times for EV charging. The ability to deliver faster charging is a key differentiator for the RCD, making it a more attractive and practical option for EV users in urban settings. The Thessaloniki pilot also demonstrated more effective optimisation of the RCD's operational time. The RCD exhibited improved balancing of its time spent charging EVs and the time required for recharging itself. This optimisation led to a reduction in downtime and a corresponding increase in overall productivity. By minimising the time the RCD spends out of service for recharging, the system can maximise its availability for charging vehicles, thereby enhancing its efficiency and effectiveness.
