Rule-based Energy Management Strategy for Fuel Cell Vehicles

In order to solve the problems of non-reversible recovery of electric energy and weak dynamic characteristics of fuel single fuel cell vehicles, this paper uses a power cell and a fuel cell to form a hybrid power system, and through the use of the power-following energy management strategy, the excellent dynamic performance of the power cell is utilized to compensate for the output of the fuel cell, so as to reduce the fluctuation of the output power of the fuel cell, and the strategy can achieve the maintenance of the power cell’s. This strategy can maintain the State of Charge of the power battery and prevent the battery from overcharging or over discharging. Through simulation analysis, this strategy can effectively maintain the stability of the battery State of Charge. The energy management strategy based on power following control proposed in this study provides a practical solution for the efficient and environmentally friendly operation of hybrid-driven fuel cell vehicles.

I. Introduction

In the automobile industry, new energy vehicles, known for their low energy consumption and emissions, offer a significant solution to the escalating issue of environmental pollution. Electric vehicles, in particular, stand out as a superior alternative to traditional internal combustion engine vehicles due to their excellent economic efficiency and performance. With the gradual maturity of fuel cell development, a new brand concept has been proposed, namely “Fuel Cell Hybrid Electric Vehicle (FCHEV) powered by fuel cells”. Fuel cell hybrid electric vehicles use a fuel cell to drive the vehicle and an auxiliary energy source to make the vehicle work more efficiently [1].
