COMPARISON BETWEEN THE TWO LEADING TECHNOLOGIES ENERGY STORAGE IN ELECTRIC VEHICLES: BATTERIES AND FUEL CELLS

There are currently two technologies that dominate the current trends of electric vehicles: fuel cell and battery. Both options generate electricity to drive electric motors, eliminate pollution and improve vehicle efficiency. Fuel cells derive their energy from hydrogen stored in the vehicle, while the batteries get the energy from grid. The two forms of electricity generation have advantages and disadvantages in terms of power density and energy density, dynamic response, refueling time, autonomy and the possibility of regenerative braking, infrastructure for recharging. The electric vehicle configuration will consist of a series of blocks that must give the system a performance similar to the conventional configuration in the same terms of speed, acceleration, time of refueling and comfort. This paper develops the analysis of current technology in the propulsion system of electic vehicles for further optimal sizing of components and systems that make the some fundamental, a study of the most appropriate for the use of either technology.
