A Novel Method for the Application of the ECMS (Equivalent Consumption Minimization Strategy) to Reduce Hydrogen Consumption in Fuel Cell Hybrid Electric Vehicles

Abstract

Fuel cell hybrid electric vehicles are currently being considered as ideal means to solve the energy crisis and global warming in today's society. In this context, this paper proposes a method to solve the problem related to the dependence of the so-called optimal equivalent factor (determined in the framework of the equivalent consumption minimum strategy-ECMS) on the working conditions. The simulation results show that under typical conditions (some representative cities being considered), the proposed strategy can maintain the power balance; for different initial battery's states of charge (SOC), after the SOC stabilizes, the fuel consumption is 5.25 L/100 km.

An Overview of Modelling and Energy Management Strategies for Hybrid Electric Vehicles

“…For the ECMS, the key is to associate electrical energy with the equivalent fuel c sumption during the charging and discharging of the battery [113]. The instantaneous consumption can be divided by the source into actual and virtual fuel consumption, expression of which can be described as: For the ECMS, the key is to associate electrical energy with the equivalent fuel consumption during the charging and discharging of the battery [113].
