Hybrid electric vehicles are getting more attention due to the fuel consumption and emission issue in megacities. Energy management strategy and battery capacity are the primary factors for the energy efficiency of range-extended hybrid electric vehicles. Iran khodro Powertrain Company has unveiled a series of hybrid electric vehicles and is improving its performance constantly. In the present ...
plug-in hybrid electric vehicles (phev) technology shows great interest in the recent scientificliteratures. vehicle-to-grid (v2g) is a interconnection of energy storage of phevs and grid. byimplementation of v2g dependencies of the power system on small expensive conventional units canbe reduced, resulting in reduced operational cost. this paper represents an intelligent unitcommitment (uc) wi...
many studies have been done on hybrid vehicles in the past few years. the full hybrid vehicles need a large number of batteries creating up to 300 (v) to meet the required voltage of electric motor. the size and weight of the batteries cause some problems. this research investigates the mild hybrid vehicle. this vehicle includes a small electric motor and a high power internal combustion engine...
The controller of the hybrid electric vehicle determines the combustion engine start-stop time, the operation points, and regenerative brake energy. The Controlling approach of hybrid electric vehicles controls the amount of needed fuel in every driving situation. In the present study, the thermostat strategy is implemented along with fuzzy logic control and compared to the classic thermostat s...
Nowadays, environmental pollution is increasing more and more and in the big cities, because of the concentration of the population, is more intense. Air pollution in the big cities has become a serious problem especially in Iran. High fossil fuel consumption of vehicles is a major cause to increase in the amount of air pollution. Using new technology of powertrain, like other developed countri...
in the present study, a model of a large lithium polymer (li-po) battery for use in the simulation of hybrid electric vehicles (hevs) is developed. to attain this goal, an equivalent circuit (ec) consisting of a series resistor and two rc parallel networks is considered. the accuracy and the response time of the model for use in an hev simulator are studied. the battery parameters identificatio...
