Well, its smart so maybe that is why it seems weird.

Do you leave hot grease on the stove top when not at home? Maybe build a big fire in the hearth before heading out?

I grew up in a house where coffee makers and toasters were never left plugged in and nothing flammable was ever left on a stove.

But I know there are people out there that fail to check to see if their gun is loaded before cleaning it, so let's just say some people make better decisions than others when it comes to risk management, particularly on life & safety issues.

I would have to agree here that a properly installed EV charger in the garage is no more dangerous than any other 240V appliance. It also makes sense not to run something generating heat when not at home (I guess I do let my furnace and water heater run).

Now I would never park an EV in my garage. You never know when those will spontaneously combust, plugged in or not.

I would agree with your premise that the properly installed charger in and of itself is not where the risk is.

The problem is plugging it into an EV that may develop a short and burn your house down.

Level 2 charging in your garage is no different than installing a gas pump and storage in your garage.

A level 2 charger is just a 40 to 60 amp 240v circuit. It's no different than putting a small cracker box welder in your garage. Or a clothes dryer.

Most homes already have 2 phase power (240V) for any number of things.

So no, a level two charger isn't like have a gasoline tank and pump in your garage. You could make an argument for a propane tank, though - those aren't a big deal, and in rural areas most of us have one.
When connected to an EV I reach a rather difference conclusion.

So in my professional opinion, it runs the same level of risk. I also do not run the electric dryer when not at home. I would advise not using a welder on an EV battery in the garage as well.

Some of us actually care about safety. Others are happy to burn alive in a totally preventable fire. You be you.

Your hot water heater runs on 240 and is always on. Lots of HVAC runs on 240 and is always on. So no, not like a tank of gasoline in your garage. I agree that the batteries are more susceptible to fires, even when just sitting there. However (like you I'm not a huge fan of EVs, just think the market should decide) arguments need to avoid hyperbole. The comparison to a gasoline tank/pump in your garage is mostly hyperbole. And no one would do that, the tank/pump would be outside. So a better point would be installing an underground gasoline tank and pump outside your garage is much safer than an ev parked in it.

And derision like your last three sentences do no good at all.

the 220 part of the HVAC sits on the outside of your house. I have a gas water heater, though both gas and electric water heaters have various safety mechanisms in place and a much, much, much (did I say much) more proven safety record though accidents still happen.

I will use hyperbole as I see fit, do not need any sort of lecture particularly when it comes to those who vasly overstate the "safety" of EVs and by those who do their own unpermitted electrical work whilst also lacking the proper expertise, training and tools.

BTW - Thanks for making my point for me. No one should put a gas storage tank and pump in their garage and no one should put an EV supercharger in their garage.

What percentage of EV's catch fire while charging. A simple rounding to the tenths place is fine.

My water heater is tankless and natural gas, as the Lord intended. The condenser is usually the part of an AC system that needs the most power, outside. An EV fire will burn a lot longer and have more energy than a gasoline tank.

It's also relatively unlikely for a car sitting in a garage with a gasoline tank, which doesn't have a whole lot of electrical components near/in it, nor is it generally interacted with outside of a gas station/outside. The only real analogous ICE vehicle situation would be for those who have CNG vehicles somehow with a home fueling station, but that represents a tiny fraction of vehicles/owners, and I haven't even read about those blowing up on folks at home.

There are 198 Million homes in the European Union. All of them are powered with 240v interior circuits inside the home powering every lithium battery in any device.

Last I checked the entire continent does not appear to be in flames.

No idea how that is relevant. Well, maybe about as relevant as the actual death rate from COVID vs side effects from the vaccine. Or as relevant as $$s spent for stacking rooskies.

You do you as for what your comfort is regarding risk of charging your EV in a garage particularly as it relates to unpermitted, novice electrical work. Trust me, I am perfectly fine differing with you when it comes to risk management.

That is funny and indicative of one who has a very very poor understanding about how electricity works. Not even worth further discussion, not even sure why I started. But me thinks your comment above will get some laughs today.

This coming from the person who didn't know the difference between Level 2 and 3 chargers.

I would assume when doing your risk analysis for EV fires and safety you'd probably want to start with the rate at which they are catching fire.

1 in 100 is pretty dangerous. 1 in 1 million is not. So where did you find the rate to be?

Nope, the air handler also operates off 240V.
SockStilkings

You sure about that? I only have them for the condensers. All the furnace / air handlers are on 110. If the 220 breaker flips, I get air flowing but its not cooled.
The Fife

Positive, I replaced the fan controller in my air handler earlier this year and it has two hots going in. The old unit that dated back to around 2006 also ran off 240.

Bizarre, all my interior air handlers / furnaces are 120v. The 240 breakers are all to the condensers outside. I can turn off all the blowers via light switch by each unit in attic.

Maybe we are talking about different components. When I say air handler, I am talking about the blower motor that pushes the air through the system, hot or cold.

You'd be surprised at how many things can be 240v. Like I said. Literally everything in a European home is 240v.

Spent plenty of time in Europe so you keep talking about things in a manner that is irrelevant to the thread at hand and above somments.

Regarding air handlers in my house, they are are on 120v circuits and breakers. If that is magically turning into 240v at the unit in the attic, that's impressive. But its not what I see when I look at my breaker panel, what I see in the attic, and what I have experienced when capacitors on the condenser goes bad and trips the breaker.

Your house is one of millions and different units have different requirements.

It's relevant because you have an entire continent of homes on 240v with no issues at all.

I don't think anyone has a problem with 240v. Not sure how you made that leap but I rarely follow your logic trails.

I said to the other poster perhaps we have different experiences or potentially referring to different things.

Not sure why you feel the need to continue to interject with incomplete information and making comments about things that were not said.

Yep, that's exactly what I'm talking about. The air handler up in the attic. I've never seen one that didn't have a 240V run up to it, just L1, L2, ground.

edit: maybe, conceivably 120 only for an air handler that only has a gas pack installed but these days that still sounds like a rare bird. Straight electric or a heat pump with backup strips is going to need 240 in order to put out a substantial amount of heat.

edit: called up a friend and he confirmed they do exist but are rare enough to be non-stock items. Everybody's right I guess

Interesting. Maybe electric furnace? Mine have all been gas. That may be the "disconnect", no pun intended.

Just saw your edit, appears we reach the same "a ha".

Some electric heat pumps will have a 240v resistive heating element in the inside unit for emergency heat.

What I find humorous in the "supercharger" comments above is that I used it as a generic term. A certain poster assumes that I mean the Tesla brand name for their Level 3 chargers... Supercharger. Was wondering how they leapt to such a poor, incorrect conclusion about what I was referring to.

Sorry, although I'm on your "side" on this issue, a destination charger (level 2, 240) isn't a supercharger, and no one would refer to one as such.

Yet, I did. If its more than an extension cord than its a supercharger to me.

So is the nomenclature not Level 1, Level 2 and Level 3 but is instead 'unknown name' or extension cord, 'destination charger' then 'supercharger" but only the Tesla one or does 'supercharger' or 'Supercharger' work for all varieties?

Will Level 4 be a super-duper charger, mega charger, etc?

Unknown terminology yet another reason the EV push is dumb. Too many prima donnas trying to collect cool status with their ipad on wheels and secret code talk.
