House flooded then Tesla burns it to the ground.

You guys are missing a big issue. In PA where were are one of the rust belt capitals, in march or april we will get freezing rain, then they roll the trucks out a spray mountains of chemicals and salt on the roads. It does not rinse off very quick, even if the rain continues about 40 degrees. Wont this salt make it into the car just like it does on ICE vehicles.

Lithium batterys do not like to be bent either, so what happens when you get some internal chassis rot in 7 years. The battery make not like this.

Salt corrodes metal on any vehicle. It doesn't matter if it's ice or electric. And it doesn't take long. The difference with EV's, is you have additional worry about salt water compromising the batteries. Not just destroying metal through corrosion.

This can and does cause fires. We've seen this with most every major storm that hits the south and east coasts lately. After a week or less, here come the EV fires.

In the Midwest I've seen roads so heavily salted, that when they finally do dry, there is white dust everywhere. After the next rain or snow, it instantly dissolves into salt water.

No worries there's enough of an agenda to overlook any shortcomings or problems that might be associated with them. Things like problems with the grid, floods, or the dangers and additional costs associated with them if the do go on fire for whatever the reason may be.

No agenda is going to stop progress. It may slow it a bit, but fear mongering only goes so far. Big oil isn't going to be able to torpedo EVs

I didn't say it would stop progress, maybe only turn the other cheek. I won't be parking one in my garage so I'm really not worried.

They don't have to. What little they're losing selling oil for ICE, they will more than make up for in fossil fuel for electricity production.

The US auto makers are losing their shirts on EV's. The bulk of the driving public want nothing to do with them. Sales prove that very fact.... As does their horrible resale value.

Sales continue to rise. Resale is due to ignorance and fear of battery failure. You'll see, in 10 more years it will be beyond debate.

As will the soon to be obsolete lousy/dangerous choice for the current battery technology. Regarding resale, there's no denying the lousy resale numbers, ignorance or not, the market determines those figures.

Im not so sure. On the previous page I posted that these batteries are vented. Vents are designed to prevent water intrusion but I suspect if the entire battery is submerged the possibility of water can enter. I honestly do not think road salt will matter but I do admit. It would be on my mind driving on salted/treated roads. Yet I think unfounded unless the battery gets submerged OR less likely (maybe) a damaged protective case allows road salt intrusion.

Agree and I do not follow “why” but I thought I read somewhere something about a vent?
I tend to agree with everything you said, but I’m wondering if the sealed battery is 100% sealed, or not for a reason.

OK, I found it! With that said I don’t have enough interest to know if it’s because of a faulty vent or a compromised shell that the batteries enclosed or is it impossible to completely seal a lithium battery in an EV?

I just found this, lithium EV batteries are vented, i’m sure those vents work almost always to prevent water intrusion. My question is does it always or almost always?
https://www.donaldson.com/en-us/ven...ecting-battery-enclosures-dual-stage-venting/

There is also a third possibility in regard to a compromised shell. We can acknowledge manufacturing defects, but what about simple issues and owner runs into in every day use of the car possibly compromising the case but I think it might have to do with the vent. Interesting subject, but one that I haven’t followed up with

I figured it was vented, but I don't know where that vent is placed. I would hope it would be higher than the floor pan of the car.

I've seen many tear downs of the Tesla battery and the way the adhesive for the shell is applied, it's seems a bit haphazardly done. There's a lot of it. I'm sure it's possible to miss a spot or if it's not done evenly that it might not properly seal.

Dude. The packs are sealed. Volvo actually pressure tests the pack when they do repairs on them to ensure no leaking.

This should help you understand the venting or help me, I dont know which -

"A thermal management system is provided that minimizes the effects of thermal runaway within a battery pack. The system is comprised of a sealed battery pack enclosure configured to hold a plurality of batteries, where the battery pack enclosure is divided into a plurality of sealed battery pack compartments. The system also includes a plurality of battery venting assemblies, where at least one battery venting assembly is integrated into each of the sealed battery pack compartments, and where each of the battery venting assemblies includes an exhaust port integrated into an outer wall of the battery pack compartment and a valve, the valve being configured to seal the exhaust port under normal operating conditions and to unseal the exhaust port when at least one of the batteries within the battery pack compartment enters into thermal runaway."

I think this explains it better. Obviously it is a weak spot or Tesla themselves would not tell you to park your Tesla away from structures if submerged in salt water. I mean, it really doesnt need more explanation than that.
But here is an SAE story.

That's Volvo. I haven't heard much about water ingress on theirs, but there's been a few, though rare occurrences with Tesla. That could just be sheer cars on the road, but I wouldn't think water up to the floor boards should compromise the battery if properly sealed.

I think all electric cars have venting. Everything I read says it is necessary to prevent explosions in severe conditions. If it was possible Tesla would have already been doing it. Got to allow for expansion or boom!

You're right. EV fires get blown out of proportion and we should ignore ICE fires while we're at it.

They aren’t blown out of proportion, they are really bad. The Pinto fires weren’t ignored. People who weren’t born then know about it. Gas car fires have nothing to do with fixing ev fires. That makes it sound like don’t talk about Tesla fires because the stock might go down in my account. Gas car fires is just another look over there, pointing at something else.

I'm just saying every recall references a fire these days and everyone has had them. We get one or two Tesla fires and it gets blown out of proportion, national news. I didn't say not to talk about them, but ICE fires don't become national news. They're hit pieces.

I have to agree on this.
The recent Florida storm saw three significant EV fires involving late model Tesla vehicles do to salt water immersion. One of those fires burned down a house because it was in the garage. I do not think you will find gasoline fires like this in the recent flooding. Keep in mind there are 98.5% gasoline cars on the road of all different ages compared to the more recent 1.5% (if that) Tesla's on the road.
Im not taking sides but the math is there. I have no problem with EV's my only problem is ignoring weaknesses. I do think over time they will work this out, they have to if EVs are going to one day make up the other 98% or so of the market.

Another fact is gasoline vehicle instructions make no mention to move the vehicle 50 feet away from the house if submerged. Tesla does.
