This paper describes a vehicle simulation, originally designed for a hybrid (battery and fuel cell) short urban distances, which can be used to estimate the hybrid vehicle battery, fuel cell and/or hybrid system (both systems working together) range. The simulation model is a function of many mechanical and physical variables that depends not only on the vehicle but also on the ground. It includes the simulation of each of the elements that make up the ecological scooter, so much the driving system whose main element is an electric motor, as the energy storage system whose main element is an acid lead battery fed by a hydrogen fuel cell. An analysis of energy efficiency and operation of the vehicle is made. This Project is framed in a context that seeks an environmentally friendly alternative to current motorcycles in order to reduce polluting emissions, more precisely greenhouse gases, encouraged by the Kyoto Protocol. From simulation environment, some all these tasks can be performed. The application of this numerical model is to help to conceptual design and unit sizing of a real life-service battery, fuel cell-hydrogen and hybrid vehicle, and permits to predict the vehicle range and hydrogen and energy consumption. Results of simulations both driving cycles and real routes test are presented. Some aspects as CO2 emission saving, hydrogen consumptions an many other have been considered.
