RESUMO

This work introduces an Energy Management strategy, for electrical vehicle applications, based on a fuzzy logic supervisory system that is able to combine three different power supply sources, i. e., fuel cell, battery and supercapacitor. The supervisory system coordinates the power flow between the power sources so that the system is able to provide high power quality, which is needed to achieve the desirable dynamic performance of the propulsion system. The proposed energy management strategy of a multiple input power electronic converter takes advantage of the individual characteristics of each power sou rce and makes than operate atthe best operation region. Through adequate power sources arrangements and use of the available resources, the fuel cell size is reduced. In addition, the power sources? life time and the system ride-through at sudden load disturbances are increased. Simulation and experimental results of a 3 kW prototype, with real supercapacitor and lead-acid batteries bank, prove that the fuzzy logic is a suitable energy management control strategy
