There are “electric truck” conversion books from the 1970s. (Only trucks as they used lead acid batteries, which are still extremely heavy for useful amounts of stored energy.) This indicates it is not extremely complex, though possibly still very complex. (My reason for this assessment is from reading a few of them, but never implementing any of it.)
As for a detailed answer on the rest: I have no idea.




Likely a lot. I posted elsewhere, but there were books on this in the 1970’s.
