Electric Cars

The electric car is propelled by one or more electric motors, using energy stored in rechargeable batteries. The first practical electric cars were produced in the 1880s.[1] Electric cars were popular in the late 19th century and early 20th century, until advances in internal combustion engines, electric starters in particular, and mass production of cheaper gasoline vehicles led to a decline in the use of electric drive vehicles.

 Electric vehicles are the prime choice for mother nature lovers because they have no emissions. Even though they’re technically more efficient, they usually cost less per mile, but they tend to cost more upfront.

The lithium-ion battery packs that power EVs have to be plugged into 240 volts and adequate current to charge. Public charging should be viewed as an occasional convenience or a means to venture past one’s own region.

The most sensible, affordable way to own an electric car is to pay only for the size of the battery pack you need and to charge at home overnight, every night.

A buyer should determine how much range they need will have to consider the weather, because range can plummet as the battery pack cools and the occupants sacrifice range to heat the cabin electrically. According to a AAA study, EVs can lose more than 40 percent of their range at 20 degrees.

Electric vehicle are gearing up people attention rapidly and the besides chart well depict the pace and enthusiasm of prominent buyers of EV.

In India major passenger cars manufacturers eyed to launch there EVs. Some of them launched and others ready to launch or in last phase of testing.

If you decide to build yourself, that’s too possible!

It is possible to buy all the parts you need to convert your fossil fuel dependent vehicle to EV. Many people have done it but probably most of these have had to convert on a compromise… not quite the motor they’d have really wanted… just the minimum number of batteries so very low travel range… not really the best controller so its best not to drive above 50, etc. I’m not knocking any of these fellows – I deeply admire them – they have more courage and conviction than I do. And these people are helping to turn the market tides.

collect individual parts.

Here is list of basic components to start of with.

The Motor 

Motors are available in many sizes. Choose from AC or DC drive, ranging in power from 60-200HP.

The Speed Controller

Speed controller options will determine your overall performance limits.All speed controllers are adjustable (amp and ramp) so you can either feel the power or get the range (or anywhere between). 

The Battery Pack  

Here we have to choose among;

Lead-acid– batteries are the cheapest and in past most common traction batteries available. The efficiency (70–75%) and storage capacity of the current generation of common deep cycle lead acid batteries decreases with lower temperatures, and diverting power to run a heating coil reduces efficiency and range by up to 40%.[citation needed] Recent advances in battery efficiency, capacity, materials, safety, toxicity and durability are likely to allow these superior characteristics to be applied in car-sized EVs.

Nickel metal hydride-batteries are now considered a relatively mature technology. While less efficient (60–70%) in charging and discharging than even lead-acid, they have a specific energy of 30–80 Wh/kg, far higher than lead-acid. When used properly, nickel-metal hydride batteries can have exceptionally long lives, as has been demonstrated in their use in hybrid cars and surviving NiMH RAV4 EVs that still operate well after 100,000 miles (160,000 km) and over a decade of service.

Lithium-ion-batteries, were initially developed and commercialized for use in laptops and consumer electronics. With their high energy density and long cycle life they have become the lead candidate for use in EVs. Latest lithium iron phosphate lasting at least more than 10 years and more than 7000 charge/discharge cycles.
