Both hydrogen and plug-in electric vehicles offer significant social and environmental benefits to enhance energy security and reduce criteria and greenhouse gas emissions from the transportation sector. However, the rollout of electric vehicle supply equipment (EVSE) and hydrogen retail stations (HRS) requires substantial investments with high risks due to many uncertainties. We compare retail...

In this paper a new method for calculating of electric fields intensity around or inside any arbitrary shape electrode systems or conductors with the same or different configuration have been presented. As we know that in design and construction of a high voltage equipment, analysis of electric field intensity around and or inside that equipment has very important role therefore, according to p...

With the aim of reducing cost of electricity consumption and peak load reduction, tools requirement for better managing electricity consumption have become inevitable in recent years. Smart home has some equipment which are controllable and this ability is used for increasing comfort and minimizing electricity cost for residence. As a key component of smart home , Electric Vehicle(EV) ,increase...

Despite efficient carbon monitoring system and the commercialization of battery technology for intra-port transportation, port management are found not adopting these environmental yet costly equipments. Port authority who regulates environmental policies lacks leverage to impose tangible reduction on emission through concession. This model integrates sustainability into port equipment expansio...

Breaking electric contact has been made for closing the circuits, respectively for taking over the temporary current conduction or for the long time conduction also for re-opening the closed electric circuit, putting out the current in this way. Although the contacts are the small parts of equipment volume in which they were mounted, there are complex exigencies and obviously different from cas...
