You're missing the point. If there is something wrong in the electrical system and a component is draining the batteries when it is not supposed to, the batteries...ALL of them will be deep cycled. Now, Lithium-Ion batteries are way better at this than lead-acid, but it still greatly reduces their life.
Not only are they better at it, but you are talking about dozens of kWh to drain vs about half a kWh in a 12v battery. Basically it would take about 100 times as long, or 100 times greater power draw, to "deep cycle" an entire EV battery vs just a 12v without a big pack to keep it topped off.

Except when something goes wrong electrically, you have way more issues than with an ICE.
quote:
BTW just so you are aware. Ev's have just as many sensors as an ICE, if not more. Teslas have over 100 just on the drivetrain, which is pretty similar to an ICE
I'm sure there are a lot, and I acknowledged as much already. Still not seeing a thousand times worse. Any word on how EV sensors and wiring hold up vs ICE ones contending with more heat and vibration?

"The vast majority of EV charging draws less power than an electric dryer or water heater. It also happens mostly at night when the grid has excess capacity. This is not a real concern.
If everyone had an EV it would require about 25-30% more energy than we currently use. Again, this will be mostly at night when the excess capacity can handle it, plus it will take decades to reach that point. I think we can manage a 1% per year production increase. This is not a real concern."
Where does this information come from? 25-30% more energy required for electric vehicles? That 's HUGE even if it did happen mostly at night-and I'm not buying this convenient "it mainly happens at night " idea. I think part of this 25-30% happens at night but not all of it.

I think the plug-in hybrids are going to be the way to go for a while. Mrs. H2O is in the market for a new car and we're looking at the Audi Q5e. 40 mile all electric range which is perfect for running around town, but still has the gas motor for longer road trips. It's also fast with the electric and gas motors running together
I have always thought of this for a hybrid, an all electric drive for a car with a smaller ICE engine producing enough electricity only to keep charging the battery and supply electric power to the electric motors if the battery is completely dead. The ICE motor will shut off when not needed.
Battery capacity on a full charge would need to have at least a 100-200 mile range to be effective instead of 30 miles.

quote:You can take total US vehicle miles driven per year, about 3 trillion, divide by typical miles per kWh, which is conservatively 3, to get a trillion kWh required to charge a 100% EV fleet. We consume about 4 trillion kWh already, so all those EVs would be a 25% increase.

Perhaps, but we increased production by a larger amount in the 1990s alone.

My next daily commute vehicle will be electric. A coworker has one that they only charge at home. They noticed no significant increase in energy cost at home. It’s hard to argue the practicality of them for certain people. I can see why they would not fit the needs of others.

What you described is a series hybrid (vs a parallel hybrid where the ICE is also connected to the wheels and can drive the car). They are also referred to as EREV (extended-range electric vehicles), REEV (range-extended electric vehicles), or BEVx (range-extended battery-electric vehicle). They already exist in the marketplace, one example being the BMW i3 REx (now discontinued). I think all of the ones that have hit the market have been city cars with fairly short ranges even with the ICE range extender (max total range has topped out about 200m), they could certainly be engineered for much longer ranges but the concept doesn't seem to do well in the marketplace unless the manufacturers just haven't hit the sweet spot yet.

The supply is larger than the demand, yet the cheapest EV’s are still $90k a piece. You pretty much have to be a multi-millionaire or have a six-figure income to be able to afford the down payment for a car of that price.

They're still impractical as only vehicles.

I’m ready to buy an EV pick up truck…that can go 700 miles on one charge … and fully charge in about 5 mins… and cost the same as the ICV.

You could at least try to get it right. You can find them for half of this price

That’s if you’re getting a used EV. EV’s that are used get busted up more easily compared to new EV’s and have less value which is why no one wants to buy them
Posted on 7/12/23 at 5:33 am to JasonDBlaha
Are you claiming the cheapest EV is 90K?
Posted on 7/12/23 at 5:35 am to dewster
The problem mostly is cost, but those tax credits need to go away, and they need to tax them like they do ICE vehicles for the roads, since they are heavier.
There should be no more incentives (other than the manufacturer) for buying an EV.
If you commute, and have the ability to charge at home, enjoy your EV.

Welp, besides all that erroneous info, a tesla model y can be bought new for like 50k just like most new vehicles these days

Again,where does this come from?
I would think the average EV owner plugs in after arriving home from work in the 5-6 hour-which is not overnight. Early evening hours (5-8) would be high demand energy hours -admittedly I have no concrete evidence of this. How long does it take to charge an already partially charged EV?

An much more expensive vehicle that would likely be totaled in any wreck, undoubtedly will cost more to insure and you get to wait an hour to "refill" if you go on a long trip.
So much to love!

Just wait till it's time to buy new batteries
