I was quoted $15k in a Tesla service center for a Model 3 battery replacement, with parts and labor.
Wait another year. CATL is destroying the battery market with their new LFP and sodium batteries. Prices are collapsing.

Crash safety has become grossly exagerrated because the standards have been sharply rising last few years. Most 15yo cars will keep you safe just fine in a median crash.
A 15 year old car currently is going for 5 figures - not a shitbox. Not unless it’s a shelll of rust held together by bondo. Then your crash standards or whatever year are meaningless as the chassis may have 25% or less of its design strength.
some are, sure - but most aren’t. Plenty of well maintained clean 2010 model cars on marketplace and Craigslist for well under 10k.

Yes, as changing a tire is completely the same tool-and-knowledge level than repairing a EV Battery. If you would see how EV Clinic "repairs" Tesla batteries, you would not say they have any concern for liability.
> Yes, as changing a tire is completely the same tool-and-knowledge level than repairing a EV Battery. I think you are intentionally misrepresenting this and moving the goalposts to make your point. GP blamed safety and liability for the way the process looks like, not the complexity of the task. When it comes to safety you bet that an improperly installed or inspected wheel or tire can be dangerous. A short internet…
Sorry that you feel that way, it was not my intention. But improperly installed or inspected wheel or tire is A LOT less dangerous than crashed EV Battery. And in EU you have a lot of effort going even into this, Police can inspect (and does) the tire from the outside (+ regular mostly yearly MOTs). All new cars have to have pressure sensors in the tire. So I would say EU (where EV Clinic is present) is making a lot of the same strides to make everything around tires safer. And believe it or not, if you go buy any new car in EU, drive it 5 minutes and swap the wheels yourself, it'll flag an error! As the wheels need to have appropriate pressure sensors - that also need to be programmed into the vehicle for a lot of makes.
You think it's profit driven, I don't. Agree to disagree.
> More moving of goalposts mixed with not understanding what liability is, and where it belongs. So you tell me what's Tesla's liability when EV Clinic "repairs" a battery.
I was aiming at EV Clinics liability, not Teslas. And I can guarantee you that both Tesla and BMW take into consideration the bad press if someone, even non official mechanic, repairs their cars and then they kill someone/catch fire. Of course Tesla a lot less than BMW, I even have a feeling that this contributed more to how BMW does things, than profit.

Is it insane? I'm working in this field, and I know how quickly you can come up with such a number if you are BMW and you are deathly afraid that someone will get electrocuted while working on your car, driving it or rescuing someone in a crash. It's a safety and liability issue, where they go to great lengths to actually re-certify a battery after crash. The whole thing is setup so, that even the dummy electricians…
If you and BMW are correct - if we take it for a fact that a simple fender-bender can make batteries develop life-threatening faults, which absolutely require a 4k euro inspection that involves complete disassembly and specialist equipment, then that means that EVs are unsuitable for public use. So either all EVs need to be scrapped forever, or BMW needs to engineer a more tractable solution to the problem, or BMW is…
Re: BMW PHEV: Safety fuse replacement is extremely expensive

I'm sure it depends on market, but I also know 100% that if they will certify the battery as safe, and then you get electrocuted when entering your car because the battery was not safe - they will be on the hook, in all developed markets. No one else, that cares about people safety, do the same thing for under $100. Even Tesla, that almost completely disregards any safety - be it "Full Self Driving" or "let's just ch…
Do you realise how difficult it is to get "electrocuted" in a battery powered vehicle ? I suggest you document yourself on the matter. The only real issue in reality is thermal runaway
Re: BMW PHEV: Safety fuse replacement is extremely expensive
#336I sold my bmw after 15 years of multiple bmws because their design is so poor for maintenance. I had cooling system problems that required hours of labor to get to just to replace a plastic part that cost $5 where an aluminum one would cost $7.
It seems to me that bmw was designing for best case scenarios where everything goes perfectly. And since it’s supposed to go perfectly who cares if it’s $5000 to fix because it will “never break.”
Reminds me of Rube Goldberg software designs where 9 things have to happen in sequence for success.
The idea of rubust design that assumes everything breaks and you can still operate is one I value. I look for car companies (and everything I suppose) following this principle.

No, from my experience, a simple fender-bender does not cause this.

Yes, it is insane. It's a fuse. They must have some stats on how often those things need replacing and it should have been accessible. The customer has - when they buy the car - absolutely no way of knowing what kind of surprises like this there are hidden in the vehicle and besides, it kills the second hand market so you can only trade your vehicle to a BMW dealership where they can absorb those costs for a fraction…

Depends on the brand and the model, there is a trend towards higher voltages because that implies lower currents and wiring is heavy and expensive. It started out with (nominally, voltage can rise and fall based on charge levels) (30S) 144V packs, (96S) 352V is very common and there are (192S) packs that do 704V (but that are marketed as 400V and 800V respectively). You don't want to get zapped by any of these, it's…
Yikes, that sounds dangerous. I'd personally prefer e.g. 48V even if that meant some more losses and/or thicker cables.
It is.
> I'd personally prefer e.g. 48V even if that meant some more losses and/or thicker cables.
That's unfortunately not an option. The problem with the 600 to 1000 V domain is that it is able to creep where lower voltage would stay constrained and high enough that it can jump small gaps and start arcing spontaneously. The fact that it is DC makes it more dangerous still. But from an economy and practical engineering perspective it makes perfect sense. Keep in mind that these cars are often built using Lithium-Ion packs (though fortunately we are finally seeing a change here towards safer options, even if they are slightly less dense and more expensive), so the electrocution risks are small compared to the thermal runaway risks.

I’d rather not die in a very survivable crash.
Pretty much every major safety feature is an order of magnitude less meaningful than the last. If you wear a seatbelt and eschew the most risky driving behaviors your chances of getting in a crash where the difference between 2005 and 2025 matters are very, very, very, small.
Plus they have tons more auxiliary safety features like lane departure warning, forward collision warning, blind spot detection, better visibility, etc. And they are roomier, have more power, get better gas mileage, and have backup cameras and Apple CarPlay!
