If we had a rechargeable electric automobile, how much electricity would it take to recharge it?

Question

Is there an approximate conversion factor between killowatt hours of electricity and gallons of gasoline?

Answer 1

4 cents per mile is average. Of course depends entirely on amount recharged.  But this is for a 72 volt system operating allowing 25-40 mile range for small car such as volkswagon.

Answer 2

Check out the car that uses any kind of water.  Tap water, pond water, lake water, salt water and even snow.  And the only contamination from the engine is more water. Forget about Electric cars and hybrids. This is mind blowing.

Water powered cars are supposed to be out in two years. They work by taking any water running electricity through it and burning the Hydrogen fuel it produces. Watch Utube for a demo. http://www.youtube.com/watch?v=jika4nokh...

With this you can travel a hundred miles on 1 liter of water.

Answer 3

The tricky part of conversions is that an electric motor has a much wider power band than an internal combustion engine, so that less horsepower can do more.  But yes, electric is much much cheaper.  An internal combustion engine has no power at 100 rpm, for instance.  An internal engine also consumes energy sitting at a stop light.  These things make conversions complex.

Answer 4

£1.50 (or 3-4US$) for a 120 mile charge (for a Nissan Altra) - approximates to 4 gallons (probably 5 US gallons) for a typical 30mpg car.

  but each vehicle has a diffenent capacity/mpg, like comparing how much it takes to fill a Hummer with a mini.

Some cities, like Westminster, provide free recharging points.

Also, the electric car can be refueled cheaply "off-peak" and then sell unused electric back when there is high demand http://www.acpropulsion.com/technology/v...
