This is my first time posting here, but I have been on the site before and have spent many hours reading and learning, and I thank you all!
So, in the future, maybe in year or less? I would like to begin an EV conversion. I have been going back and forth on what donor I should try and get my hands on and what set-up i want to run... So, I came here... because most of you have real world experience.
Okay so the donor cars:
Ford ranger (or small pick-up)
Yes, I know these are not the best cars for a conversion (aerodynamics of a brick), but I live in New England and 4 wheel drive can be necessary at times... Therefore I would like to keep the 4 wheel drive system in tact. I know this adds weight and will kill range when used, but if I need it, I most likely wont be too far from home.
I picked these cars because I like the way they look and they are on the lighter side of 4 wheel drive vehicles, and even more so with the engine and transmission pulled out. And yes, I do not want to leave the stock transmission. I only say this because I feel like a lot of the time most of the transmission isn't used for an EV and therefore is just dead weight... so i was thinking of trying out a Powerglide perhaps one similar to this one:
But, I don't really know if this is feasible if I want to keep the 4 wheel drive.
Now for the motor....
AC is what I am thinking... for two reasons..
1. Hills. I live in a hilly area. lots of em.
2. Regen- with a slightly heavier car I think regen could be promising.
Batteries...LiFePO4.... I hope. They are light and can hold quite a bit of juice.
So here are the initial thoughts...
Jeep Wranger- Either use the AC50 or AC55, but this is where it gets fuzzy, I know that the AC50 is much smaller than the AC55, but I think it could move the wrangler with 108 volt battery pack of 180- or 200ah CALB cells.
Any thoughts on performance here? I don't need the thing to be a rocket, just an everyday driver.
any thoughts on range if the curb weight was around 3,000 lbs?
I know that the AC55 would have more than enough power (and its a lot heavier) but it needs a much higher voltage which means something like double or more of the batteries and half of the Ah per cell... so something like 70 100 ah Thundersky or CALB cells.
any thoughts on performance here? in general and compared to the AC50 setup mentioned above?
As for the Cherokee and Ranger, The setups are essentially the same, but with the Cherokee I feel like the AC50 is way underpowered for it.... and with the ranger I feel like it could go either way as well, but maybe a little more towards the AC55 side..
As for range, I would like to get the best range I can with these cars, the more the better. If the AC50 setup got better range at 108 volts and the 180 or 100 ah cells i would be more apt to go with that, but if the AC55 got a better range with more cells with smaller ah ratings, then that would be great too..
As for performance, I don't need anything fancy, but enough to go on the highway and commute to work.
and for cost.... reasonable... I want to see what is out there first before i put a limit on anything.
As for my experience, I am a young college student who doesn't know much about EVs and electronics ( I am studying to be a mechanical engineer) but i want to learn more. I do tend to set the bar on the high side, but I love to get my hands dirty, and even if I fail, i feel like i learn more setting the bar too high than too low.
And thank you for reading this novel... if you read this far
... and I look forward to hearing what you all have to say
