Economic and Energy Analysis of Hybridized Vehicle by Means of Experimental Mapping

The development of hybrid vehicles has reached in recent years a high technical and commercial importance. In general, varied vehicular settings enable a motorization with several alternatives and conventional energies combined in order to increase the performance while reducing consumption and environmental impact. In the context of hybridization, particular attention has been given to vehicles that consider a secondary driving source of electric nature, mainly in countries where its cost is relatively low when compared with the cost of fossil fuels such as gasoline. This paper aims to achieve an economic and energy analysis of a hybridized vehicle. The last one has a conventional traction front-wheel driven by an internal combustion engine (ICE) and an electric traction rear-wheel propelled by electric motors (EMs) in-wheel. Thereby, an experimental vehicle study, on a chassis dynamometer, was performed in order to obtain the maps of torque and volumetric consumption from ICE and in sequence, after fuel consumption measurements turning on and off the EMs, it was possible to calculate the power consumed by each propulsive energy source and finally to determine their respective costs.
