There are three discrete brands of batteries applied in electric vehicles that are utilized in Canada today: Lead- Acid, Lithium-ion, and Nickel-Metal-Hydride batteries. Battery electric vehicles are impelled by a battery identified as lead-acid batteries. Lead-acid batteries are merely used in commercially electric vehicle vehicles for subsidiary loads. “Lead-acid batteries are reliable, relatively low cost, and easily recycled, but they are limited by the weight and size needed to provide even a limited vehicle range. Lead-acid battery powered vehicles are commonly used in low-speed, short-range applications, such as for golf carts, local delivery, and fork-lift trucks for warehousing. These batteries are not used in the highway-capable vehicles discussed in this report.” “Lead-acid batteries can be designed to be high power and are inexpensive, safe, and reliable.” (Ontario Ministry of Transportation. U.S. Department of Energy). As a result, lead-acid batteries are efficient for the local because they do not affect the natural environment that people exist in, workers do not have to worry where to dispose the batteries when they are done with. These days’ lead-acid batteries are the most inexpensive and the majority of batteries that attract people. Because of their developed technology, low cost, and soaring availability lead-acid batteries have been exploited in nearly all electric vehicles. An alternative type of battery that has been extensively used in electric vehicles are nickel-metal-hydride-batteries. “They outperform lead-acid batteries in the total energy they can store for a given battery weight. Material costs are relatively high, but battery life is long since NiMH batteries can withstand thousands of charging and discharging cycles.” “…..offer reasonable specific energy and specific power capabilities. Nickel-metal hydride batteries have a much longer life cycle than lead-acid batteries and are safe and abuse tolerant. These batteries have been used successfully in all-electric vehicles and are widely used in hybrid electric vehicles.” “They also have a higher self discharge rate – the tendency to discharge themselves when left unused, although they are capable of delivering rapid power bursts, repeated rapid discharges with high loads reduce the battery’s cycle life.” (Ontario Ministry of Transportation, U.S. Department of Energy, Canadian Automobile Association). As a result, the nickel-metal-hydride battery is the matter that is used to store power. Nickel-metal-hydride batteries contain numerous benefits in excess of other rechargeable batteries consisting of cycle life, safety, and non- hazardous material. This type of battery is able to maintain and sustain a high discharging/charging aptitude over an excessive period of time and are sturdy. The Nickel Metal Hydride battery structure has established its advantage of its power density, energy density, and life means as a complex battery for many transportation items one of which the electric vehicle. A conclusive classification of batteries that has also been identified and utilized by electric vehicles are lithium ion and lithium polymer batteries. “Lithium ion and lithium ion polymer batteries are starting to be used in some plug-in hybrid and battery electric vehicles where they provide the major advantage of high power density. Although cost is an obstacle at present, lithium batteries are well suited to the demands placed on batteries in PHEVs and BEVs. In these vehicles the batteries must be able to withstand nearly complete discharge (or draining) of energy on a daily basis (deep discharging). Battery manufacturers also need to optimize the number of years that the battery will last, the number of deep discharge cycles that it can endure, the rate at which its energy storage capacity degrades with age, and recharge time. Battery manufacturers have made substantial progress in these areas, and continuing technical advances will lead to even
China’s Electric Vehicle Policy
Wa n g Ta o
Electric vehicles offer China an opportunity to reduce its reliance on foreign oil, improve air quality by curbing
emissions from the burgeoning transportation sector, and enjoy the future economic benefits of being a global
pioneer in an emerging industry. While the government has prioritized the development of electric vehicles, more
can be done to ensure success.

Electric cars are squeaky clean, of course, in the sense that they don’t burn gas. With no engine, no gas tank, and no exhaust, they’re considered to be zero-emissions vehicles. But there’s more to a vehicle’s environmental impact than what comes out of the tailpipe. The Tesla doesn’t run on air. It runs on electricity, which in turn is generated from a range of different sources, from nuclear fission to natural gas to the darkest, dirtiest fossil fuel of them all: coal.
So if you’re going to stack…

Although it might not seen like a reality if could be possible if they were more electrical vehicles been used. The United States should promote the use of electric vehicles because it will achieve freedom from oil, The United States will spend less money, and it will be less air pollution.

BOLD IDEA Reengineer the grid around electric vehicles.
The first mainstream plug-in hybrids and fully electric vehicles (EVS) are just now hitting the market, and while initial sales have been slow, the Department of Energy predicts there will be 1.2 million of them on the road by 2015. With the EV revolution in full swing, University of Michigan mechanical engineer Jeffrey Stein says the time is now to integrate the electrical grid with the transportation infrastructure and ensure the country's…

which allows a vehicle to recapture and store part of the kinetic energy that would otherwise be 'lost' to heat when braking. Or, A regenerative brake is a mechanism that reduces vehicle speed by converting some of its kinetic energy into a storable form of energy instead of dissipating it as heat as with a conventional brake. The captured energy is stored for future use or fed back into a power system for use by other vehicles.
Electrical regenerative brakes in electric railway vehicles feed the generated…

Electric Vehicles and the Crude Oil Market
Paul M. Comolli
8 May 2014
Now, maybe more than ever, would be the best time to think of alternative power for transportation. Most importantly when the price per barrel of oil is again, peaking up over $100. Although the price of gas is inelastic, society should still seek out more cost effective and efficient ways of alternative transportation. Transportation is…

Electric Versus Gasoline Vehicles: Which One is Better?
Over the past few years, electric vehicles have been popping up all over the place. Why you might ask; well electric vehicles are one of the latest trends in staying “green”. Even though Americans have been using gasoline power since the invention of vehicles, electric vehicles are viewed as better than gasoline vehicles because of fuel efficiency, carbon emissions, decreased…
market has slipped in recent years. The Honda Insight was introduced to the U.S. market in late 1999, the first hybrid available to American car buyers. The two- seater was discontinued in 2006, due to low sales. The Honda Accord Hybrid, a gas-electric version of Honda’s popular family sedan, also fell into the same category and did not succeed in the market. However looking in the the past few years there has been an increase in the sales for hybrid cars. We are planning to penetrate into the…
