For those of you worried about charging to 100%...

[DevSecOps]

Wow time to sell it lol ?

That's one way to get rid of me. Place your offer ?

I'm at 98.5% - 22k miles, lots of DCFC, lots of 100% charges, 48A L2 every day, 12.2 months on battery age.

Nice.
Pretty warm there in Sac too......

It took me a long time to convince my Wife that charging to 100 % every time isn’t necessary and not recommended. On a side note, I have been wondering if anyone on this forum has reached 50K miles yet?

Thanks for all this info. Just got my GTP and have been charging to 100% even though others advised to 90%. I have a 40mile round trip each day and use about 16% battery each day. It has been triple digits for like 30 days so that may come down when/if it ever cools down. So by the weekend I am ready for another charge. Glad to here that it doesn’t affect the battery over longer times.

There is a forum member way past 50k but he doesn't check in very often. Probably having too much fun behind the wheel.

In your case and you have the ability to charge at home, I would recommend a 90% setting, charge daily and plug in whenever you are parked at home. There are several reasons why this would help.

1. Charging daily is better for the electrical grid assuming you set the car to charge during off peak hours (while most people are asleep).
2. Forms the ABC habit (always be charging) which really means just to get in the habit of plugging in whenever possible.
3. Will allow you to use departure times which is very beneficial for consistent range and battery health throughout the seasons.
4. Will allow the car to cool the battery while parked on plug. There are some conditions that you will need to meet in order for that to happen but leaving it parked off plug isn't that great when it's triple digits outside.

Food for thought.

Thanks for the help. I guess I was thinking that charging more times would be worse vs once from low battery to full. Also I park in the garage and our garage is cooled and heated so it stays 72 in there. But I can certainly change to charging each day. To 90% that is.

Then I guess we will have to wait for your 50K report!!

From what I've read, frequency of charging is not a factor in battery health. I suppose that's a good thing or else regenerative braking might be controversial.

I wouldn't know if the battery is or is not losing capacity. The efficiency depends on weather, traffic, etc. and varies significantly between summer and winter, and in fact it can easily vary 10% on two consecutive days when driving on the same route.

It's not frequency, it's the SOC and how fast the charging is done. The Li-ion batteries are expected to last under 1000 full charging cycles with normal charging protocol. It can increase if you charge slowly and to a lower level, it can decrease if you are DC charging every day.

That is a reasonable assumption. I think it's 6 of one and half dozen of the other kinda of thing.
Charging once a week from 20% to 90% displayed is equal to 7 daily sessions of 10% each. They both are adding 70% so the net result is pretty much the exact same. Perhaps charging daily would generate slightly less heat since its a shorter session and occurs during the coolest part of the day (overnight).

Check out the departure times. If you have a consistent time that you leave from home each day then set the car to pre-condition itself. You will enjoy that ......and so will the car. ?

Coming soon.
I have already purchased a new set of tires. The tire shop by my office has them racked and labeled with my name. I am going to have them installed just before my trip to San Diego in Sept. Going to that Fully Charged Live thing....

Maybe a community fund raiser? ?

Honestly I don't think I could even tell if there were any degradation based on range, since it fluctuates so wildly on a regular basis. I really didn't expect any significant loss before the battery warranty runs out anyway. I suspect degradation is more about the 2nd 80k miles, not the first.

I've pretty much been sticking with the "batteries like the middle of the curve better than the ends" advice. So unless I really need more, I usually live in the 10-90% area (and around home usually 40-90%). We do a lot of road trips though, so we do charge up to 100% maybe 30 times per year (the day we leave home to start a trip, and most hotel charges during the trip).

I don't like to do 100% much for a 2nd reason too -- it sometimes disables regen braking if the battery is too full. Always catches me by surprise when it does that. Only happened a handful of times but it's annoying.
