I built my own charging network and bought a portable CHAedMO unit so yeah.
But I don't want to put gas in a car a lot more than I wish I had more range.
If I was going to build one this is how I would do it.
Set a target speed and set a power base line for that speed.
Let's say 60mph. In the summer the leaf could be drawing around 15kw to maintain 60mph. When it's cold it's closer to 20kw, with a cross wind over 20kw.
Based on that I would build a leaf pusher using a 25 to 26 horsepower engine that goes on the standard trailer hitch.
I would probably also use a single wheel, single fixed speed transmission. That way the transmission would weigh almost nothing and the engine would weigh around 75lb.
Use the single speed transmission because we are assuming that the engine is needed on the highway and the the car can get up to speed under its own power.
That 25hp would provide enough power to maintain speed and give a little regen under most conditions.
