Well, I'm new here. My daily driver is a '71 Jeep Wagoneer--I'll list the specs below for anyone who's interested. I can add links to my Full Sized Jeep forum build threads too, for anyone who's interested.
So a little background, I just turned 18, and am looking to start a degree in mechanical engineering next fall. I've grown up with a bunch of cars, our newest being a '96--I took to older cars after my parents. When I was born we had 4, now we're up to 6, one of them being my Jeep. We had 7 briefly, when I had two Jeeps for a few months. I'm also super into the outdoors and just love being outside--biking, hiking, kayaking, white water rafting, etc.
Back in 6th grade I learned about what releasing large amounts of CO2 is doing to the planet, and since then have been trying to figure out the best way to make the classics I know and like, sustainable. I learned more about the other advantages and everything of EVs later, but that was what got me on this path.
Back to the Jeep, I want to keep it looking mostly stock. I'm not looking for a massive lift and massive tires--there's no reason for it. I want to keep it as a 4x4 daily driver/family wagon. I want to keep the bench seats, install my rear shoulder belts (fronts are already done), maybe shave some weight. I'd like at least a 300 mile range, which is what it has now, and similar power to what it has now.
Note: Right now I'm gonna have to be paying for college--unless I find some incredible deal, I'm not doing a conversion in the immediate future. I just can't, financially, and because it's
my daily--I can't just take it down for a few months.
So initially I wanted to retain the factory transfer case, and tie one or two motors to a three on the tree for the Jeep. Then I could put batteries in place of the gas tank, exhaust, and engine, and if I moved the spare tire to right under the hood (presumably above some batteries there). That would open up a ton of space behind the rear axle, which would also keep the weight low. I figure the controller can go behind the dash, as there is a lot of space there, and it would keep it dry. Otherwise it can go up on the firewall somewhere.
I decided that that idea wasn't the best, just because the drivetrain is so naturally inefficient. In 2wd it would have to go through the transmission, transfer case, two u joints (one of which is at a not super great angle), and through the Dana 44 diff and axles. Now, it has locking hubs, so the front driveline wouldn't have to be spun, but still, that's not a great way to use your power.
So then I've been trying to figure out the best way to improve the efficiency, and about the only one is to put the motors at the diff, either with fully independent suspension swapped in, or with a solid axle built to bolt right into the factory leaf springs. Probably I would still use the Dana 44 outers, so I could even still retain the locking hubs and 2wd option if I wanted to.
My other idea is to do fully independent suspension on all 4 wheels. Plus side there is it makes it have less unsprung weight, and it should handle better. Down side is that'd be a lot more fabrication, it'd add some overall weight, and in order to give it decent, Jeep-style flex, I'd have to do long control arms and would probahly want to go for coil overs.
Obviously I have to have regular brakes (legally), although I want regen to do most of the work. I also want to retail the original gauges (I have the speedometer, fuel, and temp gauges, an amp light, and an oil light). I want to use all LEDs to minimize draw.
It still has crank windows, a manual seat, no rear defrost or wipers, non power brakes, etc. I plan to keep it that way, although I may wire in power mirrors, but those shouldn't be drawing any power unless you're adjusting them. I have a modern (but original looking) sound system. I know heated seats are the best way to go for an EV heater system, and that's not my *** option, but if that's what needs to happen, that's what needs to happen. I plan to do Toyota electric power steering on it, and have it shut off at 30 mph or so.
I know it's heavy, and the aero is awful, but that's my goal. Hopefully some people will be interested, and be able to help me out with my dumb questions as I learn more. I've been hearing a lot about new battery technology and I'm excited to see where that goes too.

-braided stainless steel brake hoses (well bled)
-LEDs in place of most lights, plugged into stock sockets
-front shoulder belts, have to build some brackets and install them and I'll have rears
Put your build / project threads here.
I'm sure there's stuff I've forgotten but that's all I can think of right now.
Thanks in advance!
