I am not sure of how big electric cars motors are, but will 3000 watts to travel 500klms as has been suggested.
At 100klms an hour your travel time would be 5 hours or more.
So the electric car motor would have to draw less 600 watts per hour.
Is this the size of electric car motors. 600 watts? The amount 6 large old style light bulbs would draw.
