Automobile emissions such as carbon dioxide, nitrogen oxide and particulate matter are coming under progressively strict regulations worldwide. Meeting the increasingly severe requirements will require wider use of electric vehicles, including hybrid electric cars, and of high-efficiency electrified powertrains for better fuel economy. For this, implementation of still more compact, higher outp...

Federal electric vehicle (EV) policies in the United States currently include vehicle purchase subsidies linked to EV battery capacity and subsidies for installing charging stations. We assess the costeffectiveness of increased battery capacity vs. nondomestic charging infrastructure installation for plug-in hybrid electric vehicles as alternate methods to reduce gasoline consumption for cars, ...

In order to meet cost targets for hybrid electric (HEV), Plug-in hybrid electric (PHEV), and allelectric vehicles (EV), an improvement in the battery life cycle and safety is essential. One practical approach to improve performance is to use power electronics intensive cell equalizer, in conjunction with on-board energy storage devices. A new technique based on buck-boost topology to equalize a...

Plug-in Hybrid Electric Vehicles (PHEVs) offer a great opportunity to significantly reduce petroleum consumption. The fuel economy of PHEV is highly dependent on All-Electric-Range (AER) and control strategy. Previous studies have shown that in addition to parameters influencing Hybrid Electric Vehicles (HEVs), control strategies of PHEVs are also influenced by the trip distance. This additiona...

Plug-in hybrid electric vehicles (PHEVs) have emerged as a promising technology that uses electricity to displace petroleum consumption in the vehicle fleet. This paper presents a comparison of the costs (vehicle purchase costs and energy costs) and benefits (reduced petroleum consumption) of PHEVs relative to hybrid electric and conventional vehicles. A detailed simulation model is used to pre...

Feasibilities of heat and cold storage technologies for vehicles were discussed for improvement of vehicle fuel efficiency. Energy performance of a plug-in cold thermal energy storage system, in which ice slurry is produced at a stationary chiller and charged into a tank in a vehicle for cabin and cargo cooling, was discussed. Energy balance of the plug-in system was compared with onboard heat ...

The penetration of plug-in electric vehicles (PEV) into nearfuture traffic and power infrastructure is expected to be large enough to have a serious impact on the grid. If each PEV arrives at home and charges immediately, the distribution network can incur in serious problems. Therefore, the charging process of the PEVs has to be coordinated, on the basis of the grid capabilities, generation an...

In this paper, we focused on one of the important aspects of plug-in electric vehicle (PIEV) use: the PIEV owners’ behaviour modelling. In order to investigate the effect of several factors on owners’ behaviour, having a set of historical data about the customers is necessary. For this purpose, a questionnaire has been designed in Google spreadsheet and the output results of this data collectio...

The limited driving range of electric vehicles (EV) is one of the biggest deployment challenges for electromobility. We use GPS driving data from a fleet of about 1,000 conventional private vehicles collected over two years to simulate energy consumption of electric cars. We estimate how much energy is required for EV charging at home and at a secondary parking location (e.g., at work) and to w...
