This paper studies the impact of fuel-cell (FC) performance and control strategies on the benefits of hybridization. One of the main weak points of the FC is slow dynamics dominated by a temperature and fuel-delivery system. Although many researchers have investigated the use of different powertrain topologies, component sizes, and control strategies in fuel cell vehicles, a detailed parametric...

The emergence of DC fast chargers for electric vehicle batteries (EVBs) has prompted the design ad-hoc microgrids (MGs), in which use a solid-state transformer (SST) instead low-frequency service can increase efficiency and reduce volume weight MG electrical architecture. Mimicking conventional gasoline station terms duration simultaneity to several customers led notion ultra-fast chargers, cha...

Concerns over growing greenhouse gas (GHG) emissions and fuel prices have prompted researchers to look into alternative energy sources, notably in the transportation sector, accounting for more than 70% of carbon emissions. An increasing amount research on electric vehicles (EVs) their management schemes (EMSs) has been undertaken extensively recent years address these concerns. This article ai...

In a regulation application, a power supply is typically tasked with maintaining a fixed1 voltage or current in the face of possible disturbances. In a tnzcking application, on the other hand, a controller works to cause an average output voltage or current to follow a desired reference waveform as a function of time or some other variable. This paper describes a large-signal linear, multirate ...

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...

Vehicle simulation software is essential to vehicle design and development. Most current vehicle software simulations, however, require that components be specified prior to running the simulations. Within this context, this paper presents a simulator offering to users flexibility enough to add new component and use different level of accuracy. Thus a first version of a new software tool, in or...

We analyze the vehicle usage and consumer profile attributes extracted from both National Household Travel Survey and Vehicle Quality Survey data to understand the impact of vehicle usage upon consumers’ choices of hybrid electric vehicles in the US. In addition, the key characteristics of hybrid vehicle drivers are identified to determine the market segmentations of hybrid electric vehicles an...

Vehicle to Grid technology allows the batteries of electric vehicles to operate as energy storage elements for renewable energy power systems. The Z-Source inverter is a new and attractive topology for the power electronics interface. In this paper, the equivalent DC-link voltage ripple of a single-phase Z-Source inverter for Vehicle to Grid applications is analyzed in this paper before derivin...

In order to ensure superiority of fuel and improve start and stop performance of hybrid electric vehicle, battery is used in the system. Limited by vehicle’s size, traditional hybrid electric vehicles can only carry a limited number of batteries, resulting in a relatively short running distance in one battery charge cycle. To improve energy using efficiency and increase vehicle safety, composit...

GPS data for a year’s worth of travel by 255 Seattle households illuminate how plug-in electric vehicles can match household needs. The results suggest that a battery-electric vehicle (BEV) with 100 miles of range should meet the needs of 50% of one-vehicle households and 80% of multiple-vehicle households, when charging once a day and relying on another vehicle or mode just 4 days a year.
