The structures and the energy management strategies in FCHVs

Fuel cell has become one of the best sources of power source for sustainable transportation because of its low temperature chamber gas emission and high power density. Fuel cell hybrid vehicle use fuel cell and battery/super capacitor drive system. Energy management strategy is the most important issues in the efficiency and performance of hybrid vehicle systems. This paper summarizes the system structure, energy and energy management strategy of the fuel cell hybrid electric vehicle. The rapid growth of electric vehicles makes the intelligent power grid control play an important role in the management of demand. Aware of environmental issues and fuel crisis, has brought the world's fuel cell hybrid car sales.
