Apple just started rolling out the less than 100% charging in phones and watches a few months ago. Android probably a few years. I don't know where Tesla as a tech company sits for something like this.
I would assume there's software to prevent the regular charging of over 90%, but who knows how long it has been since it was properly implemented (and I'd assume it's been around for at least a few years in the Tesla software). I'm just saying maybe it's not as difficult to override as believed, which is why the criticisms are so common. But I agree that I haven't really seen true data that completely matches this.

This says a firm has monitored BEV and many are down to 64% after 3 years.
Now before someone spins this to a pure aha moment, there's a reason why many ICE vehicles were amortized down to similar levels by year 3 prior to the pandemic. Degradation is just normal and I don't believe the degradation of these batteries are linear after the first 3 years. Overhauling and replacing a battery pack by year 8-12 seems normal. Even an ICE has likely accumulated some type of major restoration/repair/major recall work by year 8-12.
IMO there's nothing wrong with a BEV down to 64% after 3 years. I'd still buy one if the market price appropriated reflected this reality and/or more. But this criticism I'm saying is severely overstated and also overly disregarded. It's like people think that two sides of an extreme opinion average out to a normal opinion. No. It's just two horribly incorrect and alternate opinions mashed together.
An opinion of whether Vancouver or Toronto is better doesn't average out to Milwaukee (around half the driving distance between the two cities). That's the annoyance I have with the BEV/PHEV/ICE debate. It's gotten about as ridiculous and bad as politics and religion in many occasions. |
First a caveat. I own/drive an EV. It is NOT a Tesla (I looked at them, and for a lot of car and some Elon related reasons, I wanted nothing to do with one).
First/second bolded part: Literally every EV has a setting for the level to which you want to charge your battery. I keep mine set to 80%. As for how hard it is to override? Overiding it isn't really a thing, It's just changing a setting. When I'm going on a long road trip, I just tap the screen and tell my car to charge to 100%, otherwise, I keep the setting at 80%.
Third bolded part: I find it hard to believe that is anywhere near the norm. My EV came with an 8 year 80% battery capacity warranty, and bear in mind that warranty has to account for people who are going to use it a lot, and not charge it in the most efficient/effective way. I suspect they've done the leg work to figure out they won't be paying out much on that warranty, otherwise they wouldn't have offered it.
BIG EDIT: I just skimmed that article, and you missed a few major points:
1) They are talking about EPA range for Teslas, and they do say the cars drop to 64% of their EPA range
2) They don't start at 100%, they start somewhere near 70% of their EPA range.
THere are a few things going on there, the first of which, is that Tesla is notorious for stretching the testing for their car's range, something other manufacturers intentionally don't do
This doesn't say the battery is declining to 64% of capacity, if more like 90% when you look at the range going from 70% of EPA rating to 64%. So you're not degrading the battery anywhere near what that 64% headline would indicate.
I've had a lot of people tell me all the reasons it was a dumb idea for me to buy an EV, and 99% of the time, they don't even have the basic facts straight.
