re: where will we get the juice for all these EVs?

A typical day's work for a vehicle is roughly 50 miles, so "needing" a charge when you get home should be a rarity. If you would routinely use nearly a full charge in a day, you probably shouldn't do something stupid like buy an EV right now. So if that 1%er of a day comes around when you burn a full charge at the same time that that 1%er of a day that starts a multi-day power outage, well then I guess you're just shite out of luck that 0.01%er of a day that comes around every 3 decades.
So, in perfect conditions...in theory an EV could charge your home for a few days?

Charge, no. Power, yes.
Damn, people on this board are so stupid they aren't familiar with batteries

Yeah. That’s the case with my iphone...for about 6 months...2 years later and I’m having to tote around my charger to make sure it doesn’t die at work.
This gonna happen with my F250 baw?

Yeah, after about 200,000 miles

10. So right now we usually have roughly 17 billion in surplus kWh produced each month. But if we convert to all electric as many want us to do in the decade, it will require over 93 billion kWh per month. How will we fill this shortfall??
Until utility scale battery storage becomes a regular thing, there is no such thing as a surplus. Electricity is pretty much “use it or lose it.” The generation fleet in the US is governed by the Regional Transmission Operators who tell them how much and when to produce power to “feed” the grid. It’s very rare to have the full fleet up and running (see the ERCOT and SPP overloads during the snowpocalypse in February).
We don’t have to build more generation to cover the demand during blue sky operations, but in peak operations, something will have to give.

Another thing often overlooked with ev's is that heating the vehicle seriously degrades the range (after the motor driving the vehicle it is the second biggest current draw) and going hand-in-hand with heating the vehicle is the fact that the batteries are less efficient when it's cold out.
Yes I'm aware that's not a big deal for some of the south but a large portion of the country drives with actual winter and this can be a major difficulty.

Keeping the inside of the vehicle warm in winter is usually the biggest drain on EV range, especially when ambient temperatures plunge below 15° F. Lithium ion batteries used in EVs also do not perform as well in cold temperatures, which can lead to further range reductions.

So,why aren’t companies selling large battery packs rather than NG powered generators as backup power for homes?

One of my top suggestions was a career that involved making and moving electricity.
Absolutely tell him to go this route. I got in the business 20 years ago and it’s where I will retire 25 years from now. Tell him to find companies heavy in the transmission and distribution side. Generation can be fickle based on the political and environmental climate. But no matter how electricity is made, it will always have to be delivered.

Don’t be surprised if you see this within the next 5 years. The technology is being furiously developed.

So the battery capacity of an EV that I can’t charge will run my all electric home(ac/ heat, water heater, microwave, tv, computer, phone Chargers) for several days?

Anyone in WI who has left their phone in the car in January knows this.
Reduced range is a reality during winter in northern climates.

They do. Google Powerwall 2. I have 3 of them in an off grid capable system.

quote:And if it doesn't need charging, then what?
Nothing unless my EV needs charging when I arrive home and then a multiple day power outage occurs and i don’t have solar power or a generator.
Also, how often are you arriving at home from driving 200+ miles that day?

In what conditions can an ICE vehicle power your home?

quote:Probably not until you've gotten a couple hundred thousand miles out of it, at which point it'll probably have 75-80% of its original capacity. At that point you will probably buy a new pack, and maybe repurpose your old one as dedicated home backup energy storage, or maybe trade it in or sell it for recycling or what-have-you. The market for "spent" batteries will obviously evolve like they tend to do.
