I think that guy is not talking sense. He reads scientific papers then puts his own interpretation on them. So what if by taking extensive pains you might extend the life of your battery by a month or so? The car itself will have rusted to bits by then.
We discussed this to death in another thread, including that stupid video. Don't worry about it. Euan McTurk is a genuine expert, better listen to him.
I would gladly listen to that expert's opinion about that paper that was released months later than the video you linked.
He would certainly be aware of any flaw in the methodology or if the findings were replicated or not.
I do not think that the conclusions of the paper are any hard to understand and I think that no matter what the youtuber from the video I linked wanted personally to convey, it does seem to align with the researchers.
Cycling near the top of charge (75%–100% SOC) is detrimental to LFP/graphite cells. Our results show a correlation between the average SOC of battery operation and capacity fade rate, meaning that the lower the average SOC, the longer the lifetime, in these 2500 h of testing.
Think what you want about the youtuber or the reseacher of the paper, but I it seems more like gratuitous
ad personam than anything else here.
As for the "extensive pains" of not charging over 40%, well as I said, I don't use that much range anyway, my car is mostly sitting. I also use a granny charger with off-hours, that is 15% of the battery per night, hardly difficult to unplug the car when it goes over my preferred threshold.
But it would be even better to be able to set the limit at 14% and then have absolutely no need to do anything.
And that is the very point to post on this topic. If I cannot have a custom limit I would still take the 80% limit back.
