Modelling and Control of a Fuel Cell and Battery Electric Vehicle for Energy Optimization

The paper describes the development of an energetic model to define a hy-brid fuel cell + battery electric vehicle for performance analysis and the powertrain optimization. In fact, it is fundamental to balance battery power-train, also considering the higher mass needed for such type of energy stor-age systems. The purpose of the paper is to develop a model capable of evaluating the consumption of a vehicle with an electric motor, finding the optimal ratio between the number of cells of the battery and the hydrogen mass to be sent in a fuel cell, to ensure a given range of 800 km. The model also describes the repartition strategy between the Fuel-cell and the battery powertrain, to maximize the efficiency of both the systems, min-imizing the energy scraps due to low-efficiency operative points.
