An ECMS-based Approach for Energy Management of a HEV Equipped with an Electrical Variable Transmission

The present study proposes an Energy Management Strategy (EMS) control for optimization of fuel consumption in a Hybrid Electric Vehicle (HEV). It addresses an Electrical Variable Transmission (EVT) based HEV and combines an Equivalent Consumption Minimization Strategy (ECMS) to a Rule-based (RB) strategy for such a hybrid system. To this end, the EVT-based vehicle is modeled and integrated into the proposed EMS in the Simulink ^® environment. The backward-facing model is linked to work with a MATLAB-based genetic algorithm to achieve problem objectives and satisfy constraints at the meantime. Investigation of the results indicates the proposed EMS improves fuel consumption and maintains the battery State of Charge (SoC) considering battery limitations.
