Very true, and it isn't mentioned enough. Also, something that is very often overlooked is the amount of charging, and how it also decreases range and battery life.Not to mention, "quick charging" diminishes battery life overall.
It is hard on these batteries to 100% fully charge them, and to constantly keep topping them off to a full charge. It is also hard on EV batteries to run them down to a very low charge.
Most everyone agrees that it is ideal to achieve the longest battery life, by keeping the battery charge level between 20% and 80% as much as possible.
That pretty much eliminates 40% of your advertised range...... Assuming that it is accurate as displayed. Most dashboard advertised ranges are optimistic, and drop off rapidly in the first 50 miles or so. (As many of these posted videos show).
Get these EV's up in years and mileage, and a battery replacement can easily cost more than the vehicle itself is worth. Which pretty much scraps out the vehicle when the battery gives out. Yes, battery technology is improving.
There is talk of, "million mile batteries". But thus far it's just talk. So all of this has to be factored in to a EV purchase. Even more so with a EV truck that the buyer intends to do any serious towing with.
