Abstract

Proton exchange membrane fuel cells are widely regarded as having the potential to replace internal combustion engines in vehicles. Since fuel cells cannot recover energy and have a slow dynamic response, they need to be used with different power sources. Developing efficient energy management strategies to achieve excellent fuel economy is the goal of research. This paper proposes an adaptive equivalent fuel minimum consumption strategy (AECMS) to solve the problem of the poor economy of the whole vehicle caused by the wrong selection of equivalent factors (EF) in traditional ECMS. In this method, the kinematics interval is used to update the equivalent factor by considering the penalty term of energy recovery on SOC changes. Finally, the optimized equivalent factor is substituted into the optimization objective function to achieve efficient energy regulation. Simulation results under the New European Driving Cycle show that compared with the traditional ECMS based on fixed SOC benchmarks, the proposed method improves fuel economy by 1.7% while ensuring vehicle power and increases SOC by 30%.
