Not sure what you will do with it, its totaled. Been reports on electrical vehicle safety, this one has 60 kilowatt-hours of energy store in a lithium-ion battery in a collision, shorted out, would explode and fry the occupants. And lithium-ion batteries cannot be fully discharge if they are, they are permanently dead and worthless.

With a 200 HP 150KW electrical motor any electrical connection slightly loose or corrected with even the slightest resistance will extremely overheat and will burn any combustible material around it, so much for plastic components.

Practically all the nuclear power plants have been shut down in the US that besides hydro only material left to generate electrical power is fossil fuels. And there are considerable losses in converting one form of energy. But what electrical vehicles are good for, move the pollution from California to Nevada.

Just like making ethanol, cuts some of the pollution down in Milwaukee and moves it up to Northern Wisconsin where we live. All controlled by idiots and this is a complement, actually morons.

Ok, here I go.

I am by far not the best expert on this, especially since my/our (apprentice) EV classes got shut down from covid. And sadly, they are not returning for the next foreseeable future. SO that being said, it means I wont have hands on a bolt for a while and I wont have access to that super nice school and its teachers to ask this very daunting question of if you SHOULD bid on that burnt car.

But if one comes into my shop, I will take a gander. I must say though, how do you get rid of the smell? Anyway, I will keep going on.

Lets try the magic of internet, and mitchel or alldata, and we can peruse and by doing so, maybe give my (what I think is) pro advice.

Ok, enough disclaimers, lets get this on.

On that side of engine has a coolant module that runs on high volatge. Could be a starting point.

Ok, now, just texted my apprentice/co worker with the link for your bid, he basically just said what I was thinking, something really high voltage shorted cuz we never see major fires like that normally unless hybrid engine for some reason blew apart and spewed raw oil on real hot exhaust, and most will know, on the ev type powertrains, the only things that get real hot are the HV components, hence that cooling module.

So let us sink that in until you respond back Bill.

I also must thank you for keeping this thread alive. Ignore the rest, ev are the futur, and we must embrace it.

Hey nickb2, I think those two attachments were meant for other threads. I'll fill you in later on where I am in my EV quest and why that hopeless burned Bolt has my interest.

The hv battery, the dual layer one I told you about in another thread is under passenger back seat, and from pics, that part of vehicle does not look burnt to smithereens. Hmm, who knew, that last word took two e's. ;)


So I dont think something exploded in the car like the other nick said, I just think a HV live cooked so hot and for some strange reason, which surely is under investigation will show why the HV relays didn't shut down. That would be my main concern as an engineer at this point. Why did the car let that happen?

dang, yup your right, sorry got mixed up. Will try later.

And I am pretty sure you have a good interest and cant wait to find out.

In mean time, I will try reloading those images from mitchel for you. And no, I am not high or drunk, just two beers in on a late sunday afternoon.

BTW, my gf is a health care giver. Shyte, one of her coworkers tested postive. What do I do now? I saw her and fed her last night.

Anyway, I will tell that to my boss tommorow, and he will decide. I do not want to risk operations at our shop, way to many ppl there need work. Including me.

Anyway, I am not one to panic much, and this thread is fun. ;)

Other Nick was referring to other EV's lithium ion batteries that were responsible for bringing airliners down and frying people to death, just saying, they ain't safe, cell phone also can start a fire in your pocket.

But the displayed vehicle looks like it had a light kiss from an Challenger 2 British tank.

Hmmm, saw an article the other day, ppl are putting bolt powertrains in some old broncos and stuff, and gm is going to put out crate ev powertrains just for the above mentioned article, they want a piece of that action. I will try to find that article again and post it here. May cool in your old bronco Billr.

;)

Its called the e-crate. This article shows for a old blazer, but I read elsewhere that some guys are using bolts as a part pin and doing stuff to old bronco and such. Great idea. I love it and cant wait to see one.

I remember they used to sell ford trans adapter plates for chevy and vice versa for engine to trans housing, so using a kit like this would work for bronco easy.

If the powertrain in that bolt in picture above wasnt hit and some of the hv wiring survived, this would be a cool project for covid downtime. ;)

Yeah, I know, I am day dreaming

That eCrate is very interesting! Chevy engines became the most popular base for us common-folk auto enthusiasts partly because the Chevy stuff was so readily available; this could endear GM to many of the new generation "wrenchers".

I am coming up on having to make a decision on that burned Bolt and even my EV quest in general. The Bolt comes up for auction next week. It is identified as a "non repairable" vehicle, so I would have to transplant into another car or run it on the street unregistered. Unregistered would not worry me so much as a "toy", but would never be acceptable for my wife to use as a DD. Any Bolts I am seeing as "salvage" are going for $10K or more. Burned one is the only hope I see of getting going on this project for a price I can justify. Frankly, I think it will go for too much, but would sure regret if I see it fetching only $1000 and I miss out on bidding. The big risk is whether the trans and battery are totally destroyed, but I am thinking the fire/heat was up above those two critical components. I can be fairly creative in repairing a damaged trans, but if the motor windings are burnt or the magnets have heated enough to de-magnetize, then I would be screwed. Likewise, I can prune out bad battery cells and re-wire as necessary. I assume all the electronics and wiring are scrap.

The problem with picking a transplant car is that I would want to move back before SRS and ABS, at least, so that means late '80s. And, I would still have to deal with getting it re-registered as an EV. A few years back that was a reasonable process, as Calif. was so intent on encouraging EVs that DIYers were embraced. I'm not confident that the situation is the same now, since we can all just run down to a dealer and buy an EV. Well, all of us rich folk... If I go back before '75, then there is no need for smog inspection, so I could just do the swap and keep existing registration. but that takes me into really old cars. My choice there would probably be a Corvair, but those are getting rare now.

During the last many months I have been experimenting with making my own motor controller; as I think that will be mandatory to get away from the stock BS-ridden PCM/BCM circus. I think making a motor controller is doable, but then handling the PS, PB, and A/C also have to be addressed. PS and PB may not be mandatory in a transplant, depending on how much battery I ended up using; but just the added weight on the suspension might be an issue, regardless if it could be steered and stopped OK. Oh, and I would not attempt regen braking for the foreseeable future. I don't think making a BMS system would be too difficult.

Again, I am at the point where I either have to commit to such a project, or cast it aside and find something else to keep me amused in my old age.

those are on driver side, and probably kept well, my main concern, the HV harness that passes on the passenger side. I think that one is 3-4 grand alone, just for the harness. o_O :eek:

That is what I was trying to download the other day, but ended up just downloading two other things I had posted for other users, again, I am sorry for that. No excuses on my end, I just stored away random junk and tried to use that. It did bot copy as I wanted to.

How is family in these times? I hope good.

Have a great presidential, I for one will be buying molson canadian beer en masse for this one!:(:giveup:

Wow, a bolt in a corvair. That is doable. Just need some machine skills, the rest should be plugg and play. Have a heads up display of what battery management is doing and regen is also possible, the rest can be sourced out for power pumps and stuff, and having those powered on 12v is also available with aftermarket kits that even warrant thier stuff.

This english language does not apply, i before e except after t, what a load of bs

I hate auto correct. Learn real french

Ok, had a bad week at work, we are way too swamped. :giveup:

Tried to bust the tekton sockets, too lazy too take time. Just used them normally, laser stuff fading quickly
