Reducing Fuel Consumption and Emissions with Optimal Sizing of the Power

Abstract

In this article, the aim is to apply and evaluate energy consumption management and emission reduction for hybrid electric vehicles. For this purpose, the modeling and sizing of the vehicle's transmission components is done and the performance of the vehicle is evaluated in the standard driving cycle. Based on the evaluation of the cost of fuel consumption for the distribution of different powers, it acts as a principle for choosing the optimal fuel performance point between the combustion engine and the electric engine. Also, the strategy for discharging the battery is examined, which is the strategy of charge depleting and charge sustaining (CDCS), in which the reduction or consumption of the battery charge is done first in a fully electric drive and then it operates in the charge enhancement mode. Then a comparison is made between the control strategy based on the role of CDCS and the sizing of the power transmission components of both battery discharge modes. Validation of the used methods is done using simulation in MATLAB space with the help of ADVISOR software and the results are analyzed
