One of the things that people do not seem to realize that affects the longevity of rechargeable lithium batteries is the effect that leaving them fully charged has on them.
Agreed. Most EV manufacturers recommended topping it off regularly at 80%, going up to only 100% when about to start a long trip to the next charger. You noted this later in your post.
...so that the 1300 pound $40,000 100kwh long range battery...
If I had to replace the battery in my EV it'd cost about $10K (if there was no warranty). Of course my EV isn't a Tesla, which stands for Too Expensive Still Liberals Adore. LOL
...battery is really only being charged to around 80% of its actual capacity to avoid this type of degradation. With proper metering this will eventually be realized by some owners but most will happily tra-la-la along never noticing that their range is much less than advertised. If your EV is not going to be used for a period of time the battery should be discharged to about 50% of its capacity which is typically about 3.8 volts per cell.
Most EV owners I know actually knew this up front before getting their EV. The same for most solar battery owners (though the solar battery specs often encourage charging them fully daily, especially the LifePo4's). The same with discharging to a recommended floor instead of all the way to 0% charge. Most EV owners and solar battery owners know this up front.
Another characteristic that most do not seem to realize that fast charging is both risky and hard on lithium rechargeable batteries.
Actually most EV owners do realize this. The EV forums are littered with discussions on how frequent is too much to charge the EV with Level 3 roadside chargers. Plus there's even discussion on Level 2 home charging speeds (i.e. is it best to charge at a fast rate of about 11kW to get a more efficient AC to DC conversion and thus pull less power from the grid. Or is it better to regularly charge at a slower rate of about 6kW which is less efficient in the AC to DC conversion and thus adds more to the power bill, but is probably less damaging to the EV battery health). For what it's worth I almost always charge my EV at the slowest Level 2 rate for it which is 5.6kW because most of my power is free from solar anyway.
And of course, there is the well known problem that when the temperatures go down the ability of rechargeable lithium batteries to perform to their rated capacity can and will drop to a very small fraction of what one would normally expect.
On that we're in agreement. I'm frankly surprised at how many EV owners who live up north that didn't study this more fully. On the EV forums I see plenty of them who knew about it, but thought they could weather it (pardon the pun) because they were a true believer in saving the planet or whatever. Now they're admitting that if they had known how bad it was they wouldn't have gotten an EV. LOL I don't see that kind of response among the few of us EV and solar owners who go into it with a small government conservative mindset (getting solar and EV to be more energy independent and prepared for the Dims making energy less available and more expensive). Most of the people I interact with who have my small government mindset are people in the south (better climate for solar and EV) who do their homework and make sure it can be efficient for them in the long run.
I can see that you are extremely knowledgeable about both EVs and solar power systems. You did your homework and have the highest chances of success especially considering the perilous future of our electric grid. Congratulations.
Usually when I point out any of these current challenges, I face derision. We have a lot of electric vehicles in our area; the vast majority are Teslas which likely have the highest level of design maturity despite their costs. I have met no owners here who have the level of understanding that you do and their lack of knowledge is likely to leave them disappointed at points along the way.
Cars, trucks and airplanes are transportation tools designed with specific parameters in mind. If you take care of them they can last a long time and give good service. I am happy to hear that you understand the limitations of your batteries. I have actually learned a lot about them through tinkering with RC models that may be applicable if we ever decide to get an EV. They typically have a high rate of depreciation, so if one understands how to evaluate the condition of the batteries that they use... it makes it much more likely that a buyer in the used market will have a positive experience.
As you would expect for a boutique product with a selective market. Think computers in 1989.
Most ICE owners can't check their oil. 2/3 of them never heard of oil.
Once they all have EVs, do you think they will turn into engineers?
