Lingering misconceptions about EVs

[ENirogus]

We just did a typical trip over Christmas to sister in law's house. About 160 miles away, a good bit of traffic, one crash delay on the return

320 mile round trip?
So in my Kia
I would find out how to charge at SILs house, I have used a very heavy extension cord[although not recommended] to plug into 120 volts. Only gives 5 miles/hr so not a full answer unless staying overnight. One can throw a few dollars for the convenience.
In my weather with only ~210 miles range at freezing, I would have to stop at a fast charger for 1/2 an hour or so on the way home.
Remember traffic is usually a plus as slow speeds increase range on an EV

l phone despite knowing that 100 is not good for it). The idea that you only fill your car to 80% is weird coming from gas-filling.

3+ years 33k miles, charge my Kia to 100 all the time. No visible change in range
This charge to 80 business has got to stop
Don't leave it at 100
If you plug in every day at the garage, which I do in the winter sometimes, yes, it would mean leaving it at 100 all the time. In that case, yes, I set it to 80.

I charge my iphone to 100 all the time. The battery is no longer what it was, but it is over 6 years old now....

I believe all the 'research' about charging to 100 is based on batteries with limited battery management, and manufacturers giving long warranties with little real experience.
Tesla has the most data, and it seems batteries are lasting better than predicted.
I don't think hybrids only charge to 80, and I could be mistaken, but I don't think the small battery cars[IE Mini SE] are seeing battery issues.

Indeed, we MINI Cooper SE forum members who follow the ABC rule (Always Be Charging) have not reported any degradation of range despite always charging to 100%.

Curiously, sometime in the last two years, MINI started recommending 80% charging, but didn't provide any software option to make charging to 80% automatic. How many MINI owners would be willing to downgrade to 92-mile range (80% of 114 miles)?

New Research Reveals EV Batteries Can Last 40% Longer Than Predicted

As an SE owner with over 97,000 miles and charging to 100% SoC every day (as @insightman points out), I have no noticeable degradation. Of course 100% is different for each EV model; MINI has a large top buffer built in so 100% SoC is probably more similar to 85-90% SoC in other EVs.

@Puppethead, it's so good to have you on the forum with your 97K-mile experience setting good expectations for the rest of us.

As my 2021 SE's odometer creeps towards 25K miles, the only thing I don't like about the car is that it's irreplaceable.

This is important info because with a smaller battery, your 0-100 cycles are higher for the same mileage as a car with a larger battery. You have put a 'eNiro equivalent' of 200k miles on your battery. There are people who no doubt know about buffer sizes with various makers, but Tesla ISTR gave you access to more of the battery, but they also have a pretty outstanding BMS so probably balances out.
Again, my point is that leaving your car at 100 percent is a bad idea. But if you are like me, charging weekly, driving daily, there is really nothing wrong with charging to 100.
