Optimum ecology driving for electrical vehicle and fabrication of small fuel cell electrical vehicle

This paper describes the consideration of an optimum ecology driving technique to be used for electric vehicles. Modern control theory is considered to obtain the optimal running pattern. A simple mathematical model of the electrical vehicle was derived based on ideal conditions in which outside disturbances are not considered. The optimal running pattern was revealed in results from a simulation in which the velocity was increased rapidly, and decreased slowly to achieve the minimum energy running. A small fuel cell electrical vehicle with a 100 W fuel cell and two hydrogen tanks of 60 NL was fabricated as a test machine to confirm the simulation results. The fabricated vehicle was able to run a total length of 29 km in two hours.
