Electric cars?




lew


I live in the uk, where there is a lot of talk about introducing new electric cars in place of petrol/diesel fueled cars.

I recently read about an electric Range rover and was wondering, do these electric cars offer less performance than petrol/diesel models?



Answer
there have been electric cars that could happily drive at 100mph if you so wished.
Performance has not been the problem, for getting an electric car into production in the past
The main problem was the Oil companies bought up the patents.... It was not in the interests of the Oil Companies to mass produce a car with no need of oil.
But times are changing. We will soon see cars on our roads, with no emissions, some form of car that self charges as you drive.
The technology already exists, dynamos on the axles, solar panels, storage cells are getting more and more efficient.
new super bright LEDs on all the lights will reduce battery drain. The car will be lighter, new alloys and carbon plastics can be as strong as steel.

Imagine an all electric car with lower running cost, lower insurance and tax, perhaps even lower parking costs.

So if you want to see the cars sooner, make the politicians work , All new cars could be electric in less than 10 years, less than 5 if we push the governments and companies to do it.

So whats next????
Electric powered Aircraft? and pollution free skies
Lets make it happen

who invented electric cars?

Q. What country invented electric cars and which country uses them the most?


Answer
Electric taxicabs were the first electric cars, built by the Electric Carriage and Wagon Company of Philadelphia starting in 1896, and used on the streets of New York to deal with the "horse pollution" of the day.
*
The country with the most electric vehicles presently is probably the United States. There are several thousand hobbyist electric cars on the road in the US, joined in 2011 by several thousand Nissan Leafs and Chevy Volts.
*
However, the lead in electric vehicles may not last long. China plans to invest over $15 billion in electric car infrastructure, and sales of the Leaf and Volt will target Europe in 2012, which is likely to be a prime market for electric vehicles - as gasoline is much more expensive in most countries outside of the US. Other electric vehicles in development at various car manufacturers have Europe and Asia as primary marketing targets.

Is it possible to have a manual transmission in an electric car?

I know that electric cars don't need a transmission at all, but that would take a lot of the fun out of driving it. Would it be possible to have a manual transmission in an electric car?


Answer
It is possible to as you said, make an electric car without a transmission. Perhaps the best configuration for this is a 4 wheel drive electric vehicle with hub motors. But with even one motor a transmission is not required.

However most conversions from an internal combustion engine to an electric motor will keep the transmission and rear axle. Although this adds a lot of unnecessary weight is makes the conversion process a lot easier. Manual transmissions may even keep their clutch but it may not be necessary or desirable to use it.

I usually drive an automatic transmission but for the last week I was in rural Georgia driving a Mazda Miata (1) on country roads. It was a fun car to drive. I enjoyed the manual transmission and steering for this small car. But back in a big northeastern city, traffic, snow, and just needing to get where I am going easily makes me grateful for the simplicity of an automatic.

Electric cars will not initially be for everyone. They may offer the most advantages for commuters who have a garage or other place to charge them. But in an interesting development, electric vehicles are being offered to niche markets at first: You have the NEV (2), the neighborhood electric vehicle for that quiet little vehicle that can give you a short hop with little fuss and no fuel. Then there is the much publicized Tesla Roadster (3) that has a two speed transmission. And last is another unique "commuter" vehicle, the Tango, (4) this is among a new class of vehicle that has been called "Narrow track vehicles" (5: interesting viewing) This last video suggests vehicles that might be considered fun to drive with or without a transmission.

What kind of engineers design electric cars?




Joseph


I'm looking for my major in engineering for sure, I'm just not sure where I want to go into it. I'm really interested in electric cars but I'm just not sure which category of engineering it falls under.


Answer
car design will mostly fall under mechanical. it took more then a certain type of engineer to design the electric car. you can help build it if your a mechanical, electrical or probably some other type of engineer related in the field.
