ENERGY CONSUMPTION AND TOTAL VEHICLE EFFICIENCY CALCULATION PROCEDURE FOR ELECTRIC VEHICLES (EV, HEV AND PHEV)

摘要

An important question regarding vehicles design optimization and environmental care are energy management strategy and efficiency determination. Automotive brands work with a wide range of technologies and electrified mobility is considered to be one of the solutions to the growing environmental question. The present paper develops a mathematical model to predict the light-duty electric vehicle overall consumed energy depending on architecture and configuration of vehicles with different degrees of electrification (e.g. electric vehicle and hybrid electric vehicle), on the type of electric motor (e.g. hybrid synchronous electric motor, permanent magnet motor or induction motor) and engine (e.g. gasoline (Otto or Atkinson) or Diesel), on technology of energy-storage system (e.g. lithium-ion or nickel-metal hydride battery) and on weight and geometry of the car being flexible drive cycles and for all types of wheel drive (four wheel, front and rear). The method is verified making a component-to-component revision through real automobiles that are available in the market to demonstrate the validity of the system.
