I am interested in creating an EV however I hear too many sad stories of lead acid batteries dying in as little as 200 days.
From what I hear, lead acid batteries do not like high current rr to be drained down too far (80 %).
To deal with high current situation, I would like to put a little "extra" power from a lawn mower engine under the hood in addition to the Electric motor & batteries.
My current thought on how to do this is to put an AC 60 hp motor / controller kit in. Now to keep the current down, I would put a 20 hp gasoline lawn mower engine on the
back shaft so when I needed 40 hp, I could get 20 hp from the 20 hp gasoline engine and 20 hp from the ac electric motor.
The Curtis controller company says that I will blow the controller.
As I understand this is exactly the way the Honda Insite works. Curtis says you need extra electronics to make it work with their controller. They will not tell me what is needed.
I can not believe I am the first person sense the beginning of time that thought about putting an electric motor and a gas engine together using a v-belt.
