Hi.

How would you add a range extender to turn the EV into a hybrid? I will need it for my idea. Existing EV or DIY built/converted.

What I'm thinking is: Range extender -> Ultra-caps -> Motor -> and batteries, if having surplus electricity.
The idea is to use ultra-caps as temporary storage to avoid unnecessary recharging for batteries. Save them a bit.
I don't think existing controllers have that kind of option. Would you use some kind of additional controller there?

I can't specify too much what I need since my idea will adapt to what is possible.

At the moment ultracaps are a white elephant
They need to go down in cost by a factor of 20 and up in energy storage by a factor of 10 to be of any use at all

Even as a small temporary storage? I just wonder about the long term cost savings when it comes to reducing small charging/discharging for batteries. Not sure how much batteries like partial discharge.
Ultracaps could serve as temporary storage for both brake regen and range extender.
So even if they cost more now, maybe in the long run it is worth.

Looks like it then, yes.
What about the range extender, anyone has done it? What would be the easiest way to make it work on an existing system?
