Efficiency Considerations for the Charge or Refill of Autonomous Vehicles - A Fast Filling Station for a Compressed-Air Vehicle

This paper presents the development and design of a fast-filling station for a compressed air vehicle dedicated to city delivery and personal transportation on short tracks. A filling station, a transfer line to the vehicle, a vehicle side reservoir, and the compressed air propulsion system comprise the compressed air powering system. The local filling station is made up of a high-performance isothermal compression system and a local buffer reservoir to achieve a very short filling time for the vehicle. After the pressures have equalized, a new air recirculation approach is investigated, which allows for the interchange of heated air with cool air from a local buffer reservoir via recirculation. As a result, the vehicle reservoir is filled to a greater extent, and the system's energy efficiency improves.
