A PEM (Proton Exchange Membrane) fuel cell city bus utilizes a PEM fuel cell engine as the primary source, and a li-ion battery system as the auxiliary power source. By optimizing the power split strategy and recycling braking energy, this kind of power-train has advantages of zero emission and high energy efficiency. However, the cost of hydrogen gas is far more expensive than that of the electric...
Fuel cell hybrid vehicles (FCHVs) have been attracting a lot of attention as well as electric vehicles (EVs) and various hybrid electric vehicles (HEVs) for environmental issues and energy crises. One of the advantages of using foregoing vehicles is saving energy during electric motor's braking regeneration. In this paper, a fuzzy logic based power management strategy considering a regenerative braking...
In this paper, a control strategy for a vehicular power system combined with a proton exchange membrane fuel cell and a battery energy system (BES) has been presented. The control, witch takes into account the slow dynamic of fuel cell and the state of charge (SOC) of BES, is investigated based on the proposed fuzzy logic control (FLC) for the vehicular power system. Fuel cell output power was determined...
One of the advantages of using electric vehicles (EVs) and hybrid electric vehicles (HEVs) is recovering energy through vehiclepsilas braking regeneration. In this paper, a regenerative braking control strategy for a fuel cell hybrid vehicular power system has been presented based on fuzzy logic. Fuel cell output power is determined according to the driving load requirement and the battery SOC, using...
