Parameter design of the powertrain of fuel cell electric vehicle and the energy management strategy

With the advantages of high efficiency and zero emission, electric vehicle with proton exchange membrane fuel cell (PEMFC) owns a broad application prospect. Parameters matching design for the powertrain consisting of electric motor, reducer, fuel cell engine and battery mainly is carried out. Drum test results show that the power performance of the vehicle satisfy the design requirements. And energy management strategies are proposed for the power sources of fuel cell and battery. Dynamic programming algorithm is applied to realize the minimization of hydrogen consumption for the power system in global scope. Furthermore, an energy management algorithm based on rules according to the system efficiency is designed for the fuel cell electric vehicle. Simulation results show that low hydrogen consumption is realized for different initial SOCs of battery.
