Hi there ladies and gents,
So I've been creeping around this site, and a few others, and wanted to post what i'm trying to plan for an EV conversion.
Long story short, where I live we can drive UTV's on the road, and I have one as a daily driver, and the ICE is getting sad. I'm going to have to dump $1-1.5k into it, or look at electric conversion.
I already own an i3, and love it, but want to convert the SxS to use around town, and occasional trips out into the woods. I'm completely sold on electric vehicles, and know their limits/etc.
Its lifted, and has a bunch of doo-dads on it that came with it, as well as being paid for, so going to keep it rather than trade it in.
We have sand and hills here, so working on some basic design parameters now, and would like to get some input.
basing this on these parameters:
1) Vehicle is about 1300lbs as it sits. has the aerodynamics of an elephant's rear end. Tows occasionally, weight of trailer is about 700lbs.
2) trying to avoid spending $6k for a kit and some batteries.
3) i don't care about power costs with recharging, as I have solar energy at my disposal.
So, for the purposes of this, here is what I have, and here is what I need help with.
1) Motor - looking at a nissan leaf motor for the combo of cheap, reliable, and readily available. Would take suggestions though. Forklift drive motor?
2) controller - Not a clue, this is the mystery I need help with.
3) Batteries - used cells from leaf/volt/etc, I have room under the seats to stack quite a few of them.
I don't need regen braking, and would like a range of roughly 30-40 miles. Top speed is 55mph or less, and most of the driving this thing does is around 25-35mph.
So here are a couple of questions for whoever might be able to help.
1) controller - this is something I don't have a clue on, except I do know that re-programming a stock on isn't happening. can someone point me to a controller to buy/build that will drive a leaf motor? I just need it to turn, and frankly probably need less than half the rated capacity of it. but fast is fun, lets face it. I've looked at Kelly controllers, and Curtis.
2) Charging - best to just use a stock charger with the batteries? I have a L2 in the garage already.
3) Cooling - do leaf motors need liquid cooling? I can always keep stock radiator if needed.
4) Specs - does anyone know rated voltage of stock leaf motor?
What else am I missing? been searching and reading all I can, but I do make mistakes like anyone else.
Thanks in advance, trying to move my whole fleet to electric by 2020, just need to figure out how to afford that Rivian R1T!
