Electric vehicles, baah.

Could you all please try and explain to me what will happen when all the electric vehicles get stuck on a free way for a number of hours in freezing conditions. With wipers going and the aircon on full and all having flat batteries.
Is this been thought out properly?????

Being as I'm in the UK, it's my bed time so I'll look at your reactions tomorrow. Night, night.

The highways here in Southwest Michigan get shut down on a regular basis in the winter. Lake effect here by Lake Michigan can make whiteout conditions in minutes. It's going to be real interesting and not in a good way. Lots of wattage to keep a vehicle and it's batteries warm.

They are not going to need tow trucks in that situation. They will need car carriers with loading winches.

Hopefully there will be four wheel drive rescue buses to keep the body count down,

Imagine the realization sinking in that the automobile chooses to save its batteries from harm and shuts the cabin heat down.

Yeah, but they could just carry a gas generator in their car with an extension cord.
Checkmate, now what?
Lol

It could be an issue with an electric car.

What I was taught to do is noever go anywhere in a car without warm enough clothes to survive if something like that happens. So if you came prepared like that with warm clothes in your car, you could shut off your gas powered car and use your clothing to stay alive, or maybe run it for 15 minutes out of every hour to keep the temperature from getting too cold inside.

The following video says that's not really an option with electric cars because if the batteries get too cold they wont work so you can't just shut it down.

He's given it some thought and gasoline cars definitely have some advantages in winter storms.

Stuck With A TESLA or Other EV In A Snow Storm - How Will The Heating Perform Compared To A Gas Car?

One thing I learned from the video...some electric cars have heat pumps and some don't. If your electric car doesn't have a heat pump, your battery will run down faster trying to heat it because heat pumps use the electicity much more efficiently (by a factor of 2x-3x) to heat your car, at least that's what the numbers in the video imply. (Heating takes 1000 watts with a heat pump and 2000-3000 watts without a heat pump).

Winter Ice Freezing Temps Electric: doesn't mix well. It would just fire their engine.

My personal take on electric vehicles: they might be great in warm sunny climates, for short distance commuters, but when you add cold, the need for a heater and / or de-icing and snow, then they will not likely ever be practical in the colder areas of the globe. And yeah, hardly anyone ever talks about this.

Edited to add: Except for H in the comment above. Respect ... I saw and agree with you, but had a lag on my end before posting

That works, but if only half to two thirds actually do that, the results are not going to be pretty.

I just leave a kit in the car that has cloths for the worst case in my area. I also do not go farther than I can walk back home in snowy conditions unless I absolutely have to until the roads are clear.

Makes sense, wonder if they use a hot water heater type deal? Heat small tank with low watt element and thermostat controlled, use low watt pump to pump through a single core radiator, and low watt fan to blow heat out off core.

Ummm…yes…the throughways will charge your vehicle as you wait in traffic…by induction…much like that smartphone of yours as it sits on your induction charger…

Pretty nifty…huh…?


C’mon guys…get the eff out your box…when you do your thinking…

Someone tried driving up a power pole when they lost control on the ice. The power is out and the trucks can’t get out there until the blizzard stops. No power to the induction system.

I hope you brought candles. They put out some heat.

Lines buried in the asphalt, just like they did with the self driving experiments before tesla and the sensors.

a reply to: beyondknowledge


Ummm…good thing we finally got rid of those 250 year old tech…poles…and buried the cables…or that just might have been a problem…

Oh…and it’s always a good idea to take BOB along…BOB…always has candles…and lighters…and magnesium…and ferro rods…and thermal blankets…and rations…

BOB has put on some weight recently…but he’s well prepared…

Don’t forget the coffee can for the candles

Is Bob big enough to save hundreds of people? In freezing weather? For a few days?

I beleave the power pole was first developed in the 1840s. Less than 200 years ago.

Not understanding your question. Are you implying gas cars dont run out of gas?

Most electrics have plenty of capacity for 99٪ of commuters. Typical commute for most people is less than 25 miles per day. A tesla has a 300 mile range. Even at 50% charge youd be fine.

We had hundreds of gas cars abandoned on lake shore drive a few yeArs ago during a snow storm. Gas or elevtric is irreldvant.

Ah the regular naive comment about EV and how all will freeze to death.

How about a bit of science, math and reality? Let's do that:

The EV I drive "only" has 93kWh. So, even if I am stuck with just 30% of charge and need 10% to get home (there is still charge after 0%, reserve), that leaves me with 20%. During driving, there is no electrical heating from the HV battery needed, a combined heat and power system does that.

That's 18.6kWh I have left for heating and lighting. Lighting is LED so that's neglectable. Let's talk about the electric cabin heater. If it uses 1kW/h (so it's always running at 1kW for 18 hours, it's blistering warm in there in no time.

So even if it had to run through to keep the cabin temperature above freezing point, that's 18 hours of reserve. With 20% battery usage and the combined heat and power system isn't even calculated in.

So yeah, it's great for likes and such but it's not very intelligently informed, your post.

Ok so a quick question here. How are dump trucks , long haul truck drivers , diesel construction equipment ( excavators , bulldozers, loaders ) going to be replaced by electric ?
