Energy Flow Control Strategies of a Fuel Cell Electric Vehicle

An energy control system, composed of a battery group and a fuel cell, was designed for a fuel cell hybrid electric vehicle (FCEV). The theory and algorithm of the energy flow were introduced in detail. Furthermore, Many optimal strategies under all kinds of driving conditions were proposed for distributing the energy between the fuel cell and the battery group. In addition, the DSP program flow and structure of the control strategies were made out.
