Yes but the tempature is way up there. Near 400 degrees even higher like 450 for combustion for some chemistries… The batteries should never see anythibg close to thermal runaway tempatures even during very hard use. Unless the vehicle or powerwall catches on fire. Even the cells hitting 212degrees F won’t do anything but lower the life of the cell. Think of literally the billions of devices now powered by lithium, phone, tablets, dozens of medical devices, cameras, cars, jump starters, planes, boats, then the rc crowd etc. And you have maybe a few dozen instances yearly and a majority of those are from cheap China junk. That’s less then, .0001 failure rate compared to the cells in use. To make newer generation hybrid cells go off which every cell that isn’t a lipo is a hybrid you really have to almost toss it directly into the flame. There are no true Imr batteries anymore everyone is running the hype of the name of being so safe. I’ll include a link below. And they have cid and ptc in the cell already. Unprotected cells already have 2 safety devices in them. Most Chinese cells don’t have these. Letting a cell vent is more safer then not letting the pressure out like some bad Chinese cells. And drawing to much current for to long the ptc breaks the connection cell is dead no longer a risk. Unless exposed to fire.
But yes it’s so common knowledge gas vehicles burn by the thousands yearly. Do we see people calling for undestructable fuel lines. No we have these little thin walled flexible fuel lines. That rupture with just a medium force collision. And we run them right next to 1000 degree exhaust pipes. My opinion is the powers that be are going to nitpick lithium cars to death. To try to keep there record profits yearly now from gas. Keep it going as long as possible. Make it look so dangerous. Like that propaganda film back in the day to ban weed. Reefer Madness I think it’s called you should watch it. You see it in every movie car crash seen get the guy out its gonna blow. You see it on the cop shows chase ends car flips and catches fire. Why am I not seeing dozens of electric cars burning and exploding everytime they wreck. The instances are so few and inbetween like with lithium powered devices each instance makes national or world news it’s so rare. If every gas car or truck that caught fire was broadcast or gas powered equipment that’s all the news would consist of daily. Just above everyone knows someone or someone who knows someone that’s had a issue with gas powered equipment. I’ve had my mower catch grass on fire from the exhaust. Gas is way more dangerous in my opinion and we ride on 20 to 50 gallons everyday like its nothing. But it would looks like a ied went off when the system fails and ignites. In fact when I was in Iraq theybwould take a propane tank and wire a detonator to it and it would take out uparmored Humvee and cut people in half. That’s how dangerous gas under pressure is. Two or 3 of them or more can stop a tank in the right circumstances. Blow the tracks off and give everyone concussions. If not TBI. I’ve never heard of lithium battery bombs. We put sandbags on the floor with almost no leg room With a electric vehicle at least you might get a warning. Warning batteries dangerously hot please exit vehicle immediately or something. And not like a fuel line under the hood wearing out. And fuel lightly spraying under the hood on the intake and catching fire. Like my moms Oldsmobile did. Little pin prick in the rubber fuel line spraying on the hot intake poof
For the powerwall thing, I’d like to see the average statistics for electrical fires in homes without and homes with a powerwall either namebrand or DIY. I’m willing to be more houses have electrical fires without them then with powerwalls
