Hi Everybody
Ive been reading posts on this forum for a while and finally thought I'd start my own topic.
I want to build an ev to drive to work (about 100km round trip) and also to have a bit of weekend fun in, maybe even eventually join a car club.
Until now Ive been into big v8 cars (3500lb plus) but because of my larger range requirements Im thinking of going for a small car, 4 seater, probably a ford lol like an anglia, escort or capri but I might also look at a starlet, corolla or mazda as often there cheaper and easier to find. I dont need sonething with insane performance but I do want to try and keep cornering performance if I can.
While it might seem strange to start a post without having a car to convert yet Im trying to do as much learning as I can 1st. I know Im going to go low tech with a 9 inch D.C. motor (forklift), keep a manual transmission and probably run a 144v system.
I have a couple of questions about batteries. How do i calculate sag so I don't drop under 144v under acceleration?
Also battery placement. Because I don't want to ruin handling and Im looking at a small car so battery placement may be tight. Ive been thinking about whether it would be possible to use narrow batteries and sit them on the floor and then build a false floor above them. Has anyone attempted this or is there some huge issue I haven't accounted for?
Thanks in advance
Brennan
