Abstract

Electrical Variable Transmission (EVT), an electromechanical device, can be considered as an alternative solution to the conventional transmission system utilized in Hybrid Electric Vehicles (HEVs). This paper presents a comparison, in terms of fuel consumption of a HEV containing an EVT, a conventional parallel topology and a series topology. To this end, corresponding simulations of these topologies are performed in presence of control strategies enabling battery charge-sustaining and efficient power split. The power flow through the components of the vehicle are attained and fuel consumption results of the considered cases are compared. The investigation of the results indicates suitability of utilizing EVT in HEV configurations with further optimization. The outcome of the current research paves its path for implementation of design optimization approaches on such systems in further research directions.
