Abstract :
This paper presents a model of an urban vehicle that was specifically designed for low energy consumption. It is the first but crucial step towards the installation of an automated energy management system on the vehicle. The powertrain of the vehicle consists of a fuel (H2) cell system, an ultra-capacitor bank, a DC/DC converter, a motor controller and an electric motor. The overall system is modeled and simulated in MATLAB. Further, an energy management strategy is described and tested. It consists of two fuzzy logic controllers, which are responsible for the distribution of power needs between the fuel cell and the capacitors, aiming in maximizing the performance and improving the fuel consumption. Several test cases are presented and compared to the on-off control approach.
