[en] The widespread operation of internal combustion engine (ICE) vehicles has today become a great cause for concern due to the uncertainty of fossil fuel reserves, energy security issues, and numerous adverse environmental effects. Alternatives such as fuel cell vehicles, electric vehicles, hybrid vehicles, and biodiesel vehicles provide the possibility to ease some or all of these concerns. The fuel cell vehicle, however, offers an excellent combination of reducing ICE vehicle problems while maintaining the performance, driving range, and convenience that consumers require. This paper documents a comparative evaluation of an extremely important facet of the fuel cell vehicle: the energy storage system (ESS). Batteries and ultracapacitors, the two most common choices for an ESS, are compared qualitatively to illustrate the advantages and disadvantages of each. Also, a quantitative comparison is made to choose the best technology for a small fuel cell-powered SUV having the design objectives of high performance and high efficiency. Practical issues such as availability and cost are also considered. The results of the analysis indicate that a battery ESS provides the best combination of efficiency, performance, and cost for a present-day fuel cell vehicle design. Yet, if the anticipated cost reductions and improvements in the energy storage capabilities of ultracapacitors do occur, ultracapacitors will become a very strong contender for energy storage solutions of future fuel cell vehicles.

[en] This paper outlined the status of the electric vehicle industry in Canada. While the low energy density of electric batteries has prevented the widespread adoption of electric-powered vehicles, new developments in nickel metal hydride (Ni-MH) batteries have provided a 3- to 4-fold increase in energy density than lead-acid batteries. The Ni-MH batteries have enabled the emergence of hybrid automobiles that use electric motors to supplement or provide traction with internal combustion engine (ICE) generators that power the motors or charge batteries. Plug-in hybrids use batteries that can be charged from the electricity grid or by on-board generators. Lithium-based batteries contain twice the amount of energy density as Ni-MH batteries, and are now being upscaled for use in plug-in hybrids. Canada has many assets that favour the development of electric vehicle technology as it has a high degree of urbanization, and a widely diversified electric supply. Canada is also a major player in EV technology, and a world leader in renewable electricity generation. However, considerable investment and leadership is needed in order to foster EV technology in Canada. It was concluded that an EV industry can be developed by facilitating collaboration among organizations currently promoting sustainable transportation, identifying potential centres of engineering and technological excellence, and defining markets relevant to a Canadian EV industry. 32 refs., 6 tabs., 4 figs

[en] If battery packs for electric vehicles (EVs) and hybrid electric vehicles (HEVs) are to operate effectively in all climates, thermal management of the packs is essential. In this paper, we will review a systematic approach for designing and evaluating battery pack thermal management systems. A thermal management system using air as the heat transfer medium is less complicated than a system using liquid cooling/heating. Generally, for parallel HEVs, an air thermal management system is adequate, whereas for EVs and series HEVs, liquid-based systems may be required for optimum thermal performance. Further information on battery thermal management can be found on the Web site www.ctts.nrel.gov/BTM

[en] Much interest has been aroused by fuel cell usage in motor vehicles, since this technology seems to overcome the conventional limits by other kinds of drive, i.e. the high environmental impact of internal-combustion engines and the drawbacks of electric battery vehicles in terms of maximum operating range and battery recharge time. After 2010 its costs are expected to fall in competitive levels with internal-combustion engines

[en] Regarding day-ahead optimization dispatch in distribution network containing large-scaled distributed generations (DGs) and electric vehicles (EVs), this paper proposes an optimization dispatch method based on conic programming. A model for dispatch that can optimize the EV aggregator charging power and the output of DGs is established. The proposed model takes the constrains of EV charging energy and charging power into consideration. In addition, DG can curtail the active power in the model to guarantee the operation safety. Then nonlinear optimization dispatch model are transformed and relaxed into second-order cone programming model to be solved. The optimization dispatch method proposed in this paper is verified by the IEEE33 node test system. (paper)

[en] With a focus on the interaction between long-term climate targets and personal transport we review the electrification of light duty vehicles (LDVs) within a model that utilizes a learning-by-researching structure. By modeling the demand of vehicles, the use of fuels and emissions implied, the model solves for the optimum RD and D investments that decrease the cost of hybrid, plug-in hybrid and electric vehicles. A range of technology and climate policy scenarios provide long term projections of vehicle use that highlight the potential synergies between innovation in the transportation sector and the energy sector. We find that even when the capital cost of electric drive vehicles (EDVs) remains higher than that of traditional combustion engine alternatives, EDVs are likely to play a key role in the decarbonisation implied by stringent climate policy. Limited innovation in batteries results in notable increases in policy costs consistent with a two degree climate policy target. - Highlights: • Significant increase in vehicles across regions in the medium to long term future. • Climate policy costs are sensitive to a lack of electric drive vehicles (EDVs). • Achieving 450ppm with no change in battery costs has a policy cost that is 2.86 percentage points higher than the base 450ppm scenario. • Climate policy hastens the introduction of electrified vehicles, however EDVs do not become the dominant vehicle of choice before the middle of the century

[en] Vehicles have become an indispensable part of every human’s life. Almost, every work depends on vehicle for transportation. Without the vehicle our work would be crucial. Though a vehicle have many benefits, it also creates a major threat for the environment by its pollution. Additionally, the existing system fails to charge the Electric Vehicle (EV) system as there is no separate charging system. This can be implemented by our proposed system wireless power charging technology using inductive coupling method. Consequently, existing system also fails to identify the theft EV in an efficient manner. This issues can be solved by using a mobile application with vehicle information. The application maintains the blockchain server which continuously monitors theft Electric Vehicle by sending, vehicle information to all rechargeable stations. In case, the theft Electric Vehicle enters the charging station the information is passed to the authorized person of the Electric Vehicle. As a result the proposed system integrates Wireless charging and anti-theft vehicle in an efficient way when compared with the existing system. (paper)
