Wrangler TJ EV Conversion

Not my site, I just happen to watch them on YouTube. Certainly a crazy amount of R&D has gone into that project, I'm sure yours is the same way.

SOOOOO crazy.

I think the first Jeep we did cost me about $324,000 and took 3 years. Painful.

But, the second one cost less, like, a LOT less. And, took less time, also, like a LOT less time.

That's the plan, right - design these such that we are refining every build to make it into a Retail Kit that can be shipped to the end customer or a builder for them to install themselves.

That's the plan.

Hey All -

General apology for my lack of timely replies, there's no good excuse for it - sorry about that.

I'll check the notifications section again to make sure it let's me know when someone has posted.

It's all good, you don't get paid to reply here😉

We ONLY convert Jeeps, not VWs, not Porches, not old Ford trucks, not old Jags, not EconoVans, not submarines (yes, I was asked to do that!), not Unimog (3 separate owners have asked), not military Humvees (4 requests), just Jeeps.

Specifically, and for right now, just 1955 to 2006 Jeeps - Early CJ, Late CJ, YJ and TJ.

So, as nice as your comment is, this and a handful of other Jeep related forums IS MY BUSINESs and every single voice, comment, complaint, question, disagreement is important to me.

When I miss a reply, it's like a gut punch of stupidity on my part.

Thanks @speeding_infraction , appreciate your reply!

To be 100% honest, I've always despised EVs, or even the thought of them. I just love the sound, rumble, feel, and smell of ICE. That said, this is extremely fascinating. I've just discovered and read through this entire thread and I like what you're doing. Seems like the perfect thing to make a 4cyl tj worthwhile. (assuming the original powerplant doesn't matter for the swap. If there's something in this thread mentioning that, I overlooked it)

No, we think all Jeep motors are crap, we can swap any ICE motor out. The motor isn't the thing, it's the adapters and couplers we had to make that join the motor to whatever transmission is stock. I do get a lot of inquiries about 4cyl though.

It's a funny thing, isn't it, change. You don't want it, you're programed to resist it, and for some reason, it seems to always require new cloths.

My path was something like this:
- Love my Jeep but hated the constant maintenance and unreliability. Traveled down the path toward a complete small v8 that came in RAMs kit. The logic being that there were so many of them that were wrecked and available, they might be a perfect fit and mix of power and reliability. Not too much but a lot more than stock.
- COVID - so, two choices, you remember them: learn play chess or take up a musical instrument. I, of course, picked convert my reasonably good and running 1984 CJ-7 to all EV, right...
- 10 months of homework, called and talked to everyone I could find. Watched every video, went to anything I could go to. Fished on forums for opinions - that didn't go well but, I could see a path. Not to start a company but to do the conversion.
- Started it, think blue painters tape, carboard boxes, 1/8" & 1/4" plywood, string, more tape. Made mockups of every part, motor, BMS, Batteries, boxes, everything.
- Played Tetris with it for about 2 months then started to commit real parts where the cardboard part was.
- More Tetris, like, a LOT more. Months of it.
- V.1 through V.20, before a V1.
- (jumping here) Driving it for the first time, still just thinking of a one off, nothing else. Driving it, that's where the change happened.
- Refine, refine, a little bit more Tetris, refine, tune, drive
- About 2.5 years into the build, it's all about driving it every single day, trying to see what explodes or falls or jumps off. What breaks under real driving.
- Then, at around 3 years, it's clear, this is a better Jeep.

At that point, something in me flipped and I began to see the path to a full blown company to do nothing but Jeep EV conversions.

My long-ass point, I wasn't looking for EVs to be part of my life, much less my Jeep life. But then you drive it, and you go from 'Oh wow, that's fun.' to 'OMG, this is better in ways I never imagined' finally to 'If I want to go get milk, I'll take the Jeep without thinking' - it's that reliable.

Still think Tesla models look like Dr. Seuss cars and doubt I'll ever own one but I have since given up my 2011 Toyota Land Cruiser (maybe the best built SUV ever made) for a Chevy Bolt EV. A great around town car that is practically free to drive.*

Long-ass rambling way to say, it took me a lot of time time come around to EV. A surprising amount of time.

- Patrick

*Ok, so, the other factor of giving that amazing car up was I no longer had any of my sons in rugby so I wasn't hauling 8-10 kids and a trailer around every single weekend. Once I got done coaching them and moved to adult, didn't need to that wonderful but horrible on gas beast. Bought it for $28k used, sold it for $22k, about 5 years of heavy use.

I could never fully give up ICE. For purposes of my love for it, as well as practicality of work and my geographic location. But fuel economy barely matters to me. I have a 02 TJ 4.0, a lifted 04 Sierra 1500 on 35s, a leveled 17 silverado 2500 crew cab 6.0 on 33s, and a lifted 16 JKU on 33s. The TJ handles 80% of MY daily driver duties, the Sierra 10%. I guess I just hate money 😂

But, a TJEV could be fun and practical in many ways. I could see myself buying a home kit one day and converting an old 4banger in my garage on the weekends.

What you've accomplished thus far is impressive to me (and well beyond my scope). I look forward to following along with all of your progress and wish you continued success!

EXACTLY - Use Case, focus on your Use Case. At around 110 miles range and about an hour charge per 18miles range, it's not for everyone. But, yeah, it fits a lot of the customers we are hearing from.

We know that, seems like you know it as well. The 'home kit' or as we call it, the Retail Kit will be available as soon as I make and install enough of them without any changes from one version to the next, then a Kit will be born.

I figure 10 TJs will get me there, we are on #3 now.

My goal is to install 10% of the 'Kits' ourselves to keep using and understanding and updating the Kits. 90% of the Kits will be Customer installed.

If we pretend we use just what you said as what you use your Jeep for, let's say you drive 50 miles to work. Once there, you should charge (lots and lots of ways to charge, more every day - office, public charge station, cord to outlet...). If you are going to leave it parked when you work, you will need about 3.5 hrs to get back to 100% (110miles range). When you get home, you plug in. If you have to go fetch something at the store, you just unplug, drive off and plug back in when you get back home. Unlike the original Mikita cordless tool batteries of yester-year, it doesn't matter how many times you plug or unplug these new batteries.

The plugging in when home is the biggest change and it only took me about 2 weeks to mentally make the switch. I leave the plug right were I park so it's right there to grab. Key Sw. OFF, exit Jeep, walk to where the gas tank fill hole is, plug in, walk away. Does it all by itself, you don't need to do anything, it will turn off when it's full.

But, it you drive longer distances, and mostly on the highway for loner distances, then this might not be for you. If you live in places that get VERY cold, you aren't a good candidate for an all EV Jeep (or most any EV).

There's a lot of casual Jeep Use Cases that work spectacularly well for this EV motor swap.

@WVJeep304 , thanks for telling me / us where your EV head is, very very interesting!

Glad that you are pioneering something like this, really hope it takes off and becomes common place. Congestion zone and ultra low emission zone charges here will eventually price me off the street.

That's the plan. Trying as hard as I can not to die trying.

I don't think this would work for how I use my TJ, but my 911 will almost certainly have a great electric option available one day should I wring the 3.8L's neck too hard.
I do wish you much continued luck.
 
If you find a city (CoSpgs) still using TJs as traffic enforcement vehicles, you might have a perfect fleet.

LA and San Diego both do. I have the contract for LA (around 30 TJs, all RHD), SD has reached out but I haven't had time or space to engage yet.

Fleet work, interesting times.

Denver also reached out. Also still can't deal with them yet.

Getting the new shop is my ONLY job at the moment.

I love Fleet wort but, retail is super important to me as well.

I haven't announced it yet but we are going to start advertising on this site and a handfull of other Jeep ONLY forums to open up our TJ line to Retail customers.

Someone already figured it out and reached out to me.

You guys, way to smart...

- Patrick
 
Forgot those fleets were largely the RHD variants. Probably a big reason they keep on rolling.

They have RHD ones for curbside reach and also they wont be getting out on the side facing oncoming traffic

Yep, that's it.

In the case of one of my City Fleet customers, they spray the gutters during the summer months for mosquiatoes, and, that's easiest from a RHD Jeep.

Same with Parking Enforcement Jeeps.

Yes, that is also interesting but, I think less OEMy - you have to basically stop to shift, if I read this correctly.

BUT, absolutely worth the effort to call Advanced Adapters when this build is done.

Very interesting.

Maybe, I wonder if you'd have to stop to shift if we did the same thing we do with manual transmissions and program in a 'motor' rpm to follow a similar path to idle speed.

Yep, gotta' give them a call later.

Thanks for that,
Patrick

This maybe been mentioned, as I am only halfway through the thread, but what about a gear vendors OD unit?
