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...
AIMS Circulating endothelium-derived extracellular vesicles (EV) levels are altered in pulmonary arterial hypertension (PAH) but whether they are biomarkers of cellular injury or participants in disease pathogenesis is unknown. Previously, we found that lung-derived EVs (LEVs) induce bone marrow-derived progenitor cells to express lung-specific mRNA and protein. In this study, we sought to dete...
Abstract: The widespread presence of uncontrolled electric vehicles causes overloading of distribution network equipment. One of these equipments is distribution transformer, which should pay attention to overloading and reducing lifetime of this equipment due to charging of electric vehicles. First, strategies have been proposed to investigate the effect of electric vehicle penetration level a...
The era of sustainable development has brought Electric Vehicles (EVs) to the spotlight. Since recharging an electric vehicle can take up to ten or more times the power consumption of a household, an increasing EV penetration in the market poses a challenge for the electricity companies. Using the Internet of Things (IoT) approach, we propose a model where electric vehicles communicate with the...
In distribution networks, failure to smooth the load curve leads to voltage drop and power quality loss. In this regard, electric vehicle batteries can be used to smooth the load curve. However, to persuade vehicle owners to share their vehicle batteries, we must also consider the owners' profits. A challenging problem is that existing methods do not take into account the vehicle owner demands ...
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...
Based on a three-dimensional morphological analysis approach embedded in an explorative technology roadmapping process, we have developed a framework which is intended to help organize the multitude of entities and functional requirements within the domain of electric mobility. The goal was to gain, in a structured way, a better understanding about this complex field. For that purpose, descript...
We present a coordination mechanism for variable-rate electric vehicle (EV) charging that combines the benefits of a decentralized decision making approach with a top-down control mechanism based on price functions. This combination allows independent decisions by self-interested EV agents, while ensuring that aggregate power demand from EV charging converges to a desired profile as determined ...
20 Electric vehicle technologies (EVs) have emerged as an important climate mitigation and energy 21 security pathway. Current research demonstrating the potential benefits of EVs has largely hinged on 22 technological and engineering design breakthroughs. However, in order for electric motive systems to 23 scale up to a level necessary to realize such benefits will require crucial shifts in ag...
This paper presents Electric Vehicle (EV) propulsion using a three phase squirrel cage induction motor. The motor control at different operating conditions is carried out by a direct torque control technique with an energy optimization strategy. The operating flux of the motor is chosen optimally using model based control strategy. Simulation tests have been carried out using MATLAB SIMULINK to...
