Research on energy management strategy of fuel cell/battery hybrid electric automobile

There are power coupling and power separating processes exist in fuel cell/battery hybrid electric automobile,whose management tactics of energy is very complicated.In order to distribute the outputs of driving force much more reasonably between fuel cell and battery,as well as strengthen it's robustness of management tactics of energy,this paper analyses theoretically the power distributing method of this Two-energy hybrid power electric automobile,which are fuel Cell and battery.Besides this,this paper also builds the simulated model of the controlling tactics of Power-Following strategy with Matlab/Simulink,as well as establishes the modeling and simulation modes of energy management system of this fuel Cell/battery Two-energy hybrid power electric automobile with the parallel framework of ADVISOR2002.The result has showed that the parameter match is reasonable for power transmission system and can meet the designing target required.
