It does make no sense why they would be willing to check the car, basically make sure it can supercharge and then never allow it to after that, including other chargers that tesla doesn’t own. I’d go around them over that, I wouldn’t bet on that being legally defense-able if they did try the legal route on someone, not their car anymore.
Your conclusion, based on ... ? So far as I can tell, Tesla is saying the car is road worthy after it passes inspection. They are not saying it is DCFC worthy.
They check the HV system at the inspection (including battery and chargers) and the car always does an internal check before it starts to charge, it’s not going to supercharge a Damaged battery salvage title or not. I see cars at the auctions with salvage titles for basic panel damage, even hail damage, nothing to do with the battery at all, so the idea that all salvage cars are total Junk and dangerous is just a naive opinion. Doesn’t help the cars value and some other things for sure though. What are you basing your conclusion on?
Under load of say ... 250 kW ? As I understand things, Tesla will turn off DCFC of any salvage car that comes to it for inspection. No choice is offered, but a car that passes inspection will then be eligible for updates and service. Draw your own conclusions, but do not presume that an inspection implies safe DCFC.
How hard would it be for Tesla to do an inspection to ensure supercharging is safe? NOT HARD AT ALL. They choose not to allow supercharging for no other reason than that it is Tesla's preference. If they wanted to allow salvage titles to supercharge it would be really easy for them to do. SO we have to ask, why dont they allow it? THey could enable it, make money on the inspection, and then make money on the supercharging.... So If they dont want to make that money, then why not? I can't see around any other reason than to sell new cars, highest margin, yeah they could make money on inspections and supercharging. But that is chump change when you could sell them a used car with high margins or sell them a new car. And it works, I dont want to ever own a branded Tesla ever again. I am all about owning a Tesla, Ive been reaching out to the used car sales team, and they suck! Having a hard time getting a call back on a couple different 2016.5 75d's. going for the low 40's. Ive got that into my salvage title car right now. I digress, Tesla wants me in a new or used car and doesnt find enough value in my business as a branded title owner.
Do you question it as an EE with in depth knowledge of Tesla cars? and if so, why? for the lay person, like myself, it appears that Tesla is more than capable of certifying a vehicle to be capable of supercharging. Especially for a car that has Not had damage past the paneling. If they can’t verify that a car is capable of supercharging then I think that they have some problems at a very basic level in their service department.
I am not voicing an opinion about Tesla and what is involved in certifying DC fast charging safely -- YOU are. And since you have now admitted you do not have a clue, I'll say that your opinion is worthless.
While I'm not a fan of the policy, it does make sense to me from Tesla's perspective. It only takes one mistake in an inspection to miss something, and imagine all the bad press of "Tesla bursts into flames at supercharging station", if they missed something in any one of these refurbishing salvage inspections. DC fast charging is the highest stress the batteries experience, by far, as well as the aspect most unambiguously reflecting negatively on Tesla if it does go wrong (they can't argue that it was a noncompliant 3rd party charger, or that the driver was driving erratically or inattentively, or anything like that like they could with most other potential Tesla mishaps.) It makes sense to argue that if it's superficial damage that doesn't affect the battery or wiring then they should allow it, but, again, I suspect the blanket policy (applying to all salvage cars, no exceptions) does make sense in an effort to eliminate any potential judgement calls (and thus potential judgment errors) on the part of the service technicians. Regarding the discussion of qualifications, I don't claim to be an expert in Tesla's electrical systems, but I have worked with electronics for over a decade, and taken some classes involving dealing with these sorts of high voltage/high current systems.
