what are the ways in which an ic engine can be replaced to make an electric car.It is to be used in small races.?


To put it simply you take the engine out and put an electric motor in its place. But its not really that simple.
If you do a search on the net you can find all sorts of conversion kits available and sites dedicated to this sort of thing.
+1. This subject is very well documented on the net. Unfortunately it is not likely to be race worthy.
Why wouldn't it be race worthy? Sure it wouldn't be good for a long race but in drag races a good electric will outdo a gas car any day. An electric car can make 0 to 60 much faster then most gas cars can. If you have enough juice and the right motor.
How many electric drag racers do you see performing??
None if any. Problem is an Electric drag race isn't as fun to watch as one with nice load engines. The race would be too quite and half the fun of the event is the roar and pounding of the engines. Not to mention he fiery crashes and explosions. Wouldn't see much of that from electric cars.
To be race worthy you have to build and electric car from the ground up. Converting a standard car to electric is a compromise. Copy the Tessla since they've already spent millions on R/D and you might have a winner.

Design your electric car and I'll design my gas car and I'll still beat you.

But I'm not saying that electric cars are not going to make a big impact in the near future.

yes definitley it is complicated and i among a group of colleagues (electrical and mechanical u.g students)are working on the project.im in the team taking care of electrical and electronics.so just curious
An advanced student who has such elementary questions is a worry - even with the language barrier.

How much have you done, how far have you progressed.

we are just about to begin! Im pretty much in to electronic stuffs so thats why bit curious!

This isn't going to work for you either. Any better than the flying car.

The problems is cars in general are very heavy. Electric motors run from batteries tend to be limited on power available.

746 watts = 1HP so a racing car might have 100+ HP which = 74600 or 74.6 KW of electrical energy - Watts is Volts x Amps

So lets say you can assemble a battery at 100 volts then you would need to be able to pull 746 amps from it to get your 74.6 KW

Apart from that amount of energy being dangerous - a battery supplying that level wouldn't last long.

Typically electric cars are very light weight and use a 80 kW (110 hp) front-mounted synchronous electric motor driving the wheels, powered by a 86 megajoules (24 kW·h) lithium ion battery pack rated to deliver up to 90 kilowatts (120 hp) power.[1][43] The pack contains air-cooled, stacked laminated battery cells with lithium manganate cathodes.[44][45] The battery and control module together weigh 300 kilograms (660 lb) and the specific energy of the cells is 140 W·h/kg.[46] Each battery pack costs an estimated US$18,000 (as of May 2010).

As you see this is complicated, not cheap and not for the amateur.
