Research on Control Principle of Fuel Cell Vehicle Powertrain

The problems discussed here include load leveling of fuel cell vehicles,battery state of charge closed loop control,and prediction control of power output of fuel cell engine,as well as regenerative braking control strategy.At the end of this paper,algorithm realization of the above control principles are summarized and exemplar field test results are illustrated.The field test results showed that,the control concept adopted could take the performance and economy characters of the components of hybrid fuel cell power train into account and give feasible control results.
