Study on power distribution strategy and optimization of fuel cell hybrid vehicles

Abstract

In this study, comparative analysis of several types of power distribution and control strategies widely developed and used in the current fuel cell hybrid vehicles is presented, involving control theory, optimization methods and application. And a conclusion is drawn that fuzzy control strategies of power distribution is applicable for hybrid system characteristics of the existing fuel cell electric vehicles and capable of keeping the auxiliary power unit in a good charge state with better fuel economy using simple controlling rules under the premise of meeting the vehicle dynamics, consequently has a good engineering prospect.
