Can we make it a Math question? (because I will clearly lose the odometer contest)

Q. "I’m currently sitting at 36,744 with no difference in mileage, I commute 204 miles a day 6 days a week, well let’s see who can solve for the day I took delivery?"

My answer: September 3, 2017 ;)

The person second on the list at over 51,000 miles has posted on this site. I am 31,564 miles and won't be putting any miles for the next 10 days since I am on vacation. Most long commuters would agree that the Bolt is pretty much the best commuting car. No wasted time in dealerships, not having to watch the 15 gallons go in the gas tank a few times a week, and the instant torque makes the car much safer when dealing with other drivers as much as we do on highways.

OMG, not hypermilers! I can't stand those guys cruising along at ten miles below the speed limit, clogging the commuter lane just to get another mpg or two. But they usually aren't EV drivers: the Prius drivers are the worst offenders. They are commonly referred to as 'road boulders' here in California.

I am probably not on the list of the most energy efficient Bolt drivers. I have averaged 3.5 miles per kWh over about 2600 of the 3600 miles on my Bolt, according to my dash display. Since electric energy is so cheap and clean, why squeeze out those extra miles? I am a leadfoot: I prefer to enjoy the acceleration of my Bolt.

But wait a minute: I might just qualify for the list. About two-thirds of my commute is on expressways, where the speed limit is 45 mph. The Bolt is much more efficient at 45 mph than at 65 mph (freeway speeds) because of it's massive drag coefficient, and I only put the hammer down occasionally.

I wonder what mileage jeff_h (see the link to the voltstats.net web page posted by GJETSON) has achieved over the 57,000 miles he has put on his Bolt. I can't see any info on his energy consumption on that web page. I also wonder if he has experienced any battery degradation.

I hate to say this, but battery degradation is almost nonexistent even for people who have 50,000 miles on their cars. The guy who has over 50,000 has a youtube channel New Coulomb and he said his degradation is less than 1%. My car, which has almost 32,000, has about the same degradation. However, I think I just got a lower capacity battery than many users here. My car has always been in the 55 to 56 kWh capacity range. I can't find 1 Bolt user that has even mentioned ANY battery degradation. Battery failure is prevalent, but no degradation. Even the Tesla data I have seen has had much more initial degradation than the Bolt.

People that are long commuters tend not to be hypermilers, we have other things to worry about. My route involves 90% of the mileage where I travel between 70 to 75 mph.

Thank you all for the reply, I’m glad to see that someone is at the 50k mark, truth be told I’m somewhat hesitant to take it into the dealership for any type of updates despite the current recall with the module 2, you never know, maybe GM did such a great job initially that now they want to tweak these bolts by lowering the mileage or start electrical issues to make them come into the dealership more often then not, not sure what you folks think on that, but that’s my 2 cents.

I've logged almost 20k miles in my Bolt since Dec '16. When it was brand new, I observed it would be at 96.5% raw SOC via TorquePro when charged to 100%.
I did a 100% charge recently a couple of times, and I observed 96.1% and 96.5% SOC readings, which may be an indication of an ever so slight degradation of 0.4% (almost negligible really). If I have lost 0.4%, that is not bad at all after 20k miles. I have a feeling the overwhelmingly majority of Bolt owners will never even come close to the 40% degradation in 8 years GM warrants the Bolt's battery for.

I usually use HTR and only charge to full before road trips, and I probably DCFC 15-20 times a year.

It's always seemed patently obvious to me that this must be the case. There's no way that GM would offer a battery warranty that would require them to replace more than a tiny fraction of batteries. They've clearly done their homework and tested the be-gee-sus out of these batteries before coming up with those warranty terms.

On the bell curve of battery pamperers to battery abusers, only the worst of the very worst abusers are likely to get close to warranty replacement territory. Those of us who try to take it easy on the batteries will fare far better.

But what constitutes 'abuse'? Is it overcharging (charging the car to 'full') or letting the charge get low ('orange' warning)? Is it using maximum acceleration frequently? Is it running or parking the car in a hot (or cold) environment? I think we all know that neglecting maintenance can be ruled out, since none is required for the first ten years or so.

I think we're all pretty well agreed that extremes in state of charge, charge/discharge rate and temperature are bad for the battery. The Bolt uses active measures to avoid the worse excesses in all three of those categories, but I think "abuse" would constitute testing those limits repeatedly on a regular basis.

Yes, driving super aggresively, charging to full and draining to near empty very often combined with multiple fast charges a day, and living in a climate with cold winters and hot summers.

Even with all that, I still think the Bolt wouldn't come close to 40% degradation within an 8 year/100k mile period.

I have 48,424 miles and bought one of the first bolts in December. Shipped it from California and started driving Jan 9th. I am 3rd on voltstats as posatronic.
I have from .4% to 1.5% battery degradation. You can figure this out with he chevy app. In th app one screen shows what KWh are left. Take that number from 100 and you have percent used(but no decimal bummer) then take KWh used and divide by percentage used. The difference between that and 60 is your degradation.
The only abuse is level 3 charging. The less you use lvl 3 the better the degradation. Read Tesla forums. Their cars reduce the total charge unless the owner overrides. ATM takes care of battery too hot or cold.
When people say full charge it’s really 90%. Since people have estimated that the battery is about 66/68 kWh total. When empty (<10 miles) it’s not empty the car won’t let you. It will always have 3-5kwh won’t let you use for battery life.
The one thing that has stayed the same on batteries since the invention and the same with these is they are best in a state of charge or discharge. (Ice cars constantly charge and discharge the 12volt battery) I drive 130 miles every day and I am always in a state of charge or discharge. That’s one reason why I don’t have a lot of degradation. And GM making a good battery.
Leaving car for weeks at a time with SOC more than 55% will cause degradation as well as less than 10%.
Don’t over think this battery stuff. Just drive the car like you would normally. If you drive short miles, charge once a week with hilltop. If you use 50% to 100% everyday then charge everyday. ( I program to be ready 1hr before I leave )
Enjoy driving 100% emmisions free vehicle.

Reason being: I don’t fast charge that much. Always keep the battery between 90 and 30% don’t remember if have ever dropped blow that. And yes my workplace has a punt 3-4kw almost trickle joke of a level2 charger that actually served as a boon

As BEV range increases, there will be more driven more miles. However, we're averaging 400 miles a month, strictly urban use.

When the i3 was introduced with less than 100-mile range, I was shopping for a BEV and couldn't believe how many nice i3s there were for sale and lease returns with very few miles on them and at incredible bargains. We chose to pay nearly MSRP for the then-new 2017 Bolt because of the range and the one-pedal. Experience has shown for our local use we'd have been fine with the range of the used i3 and had the $20K difference for a few years of dead-of-winter snowbird vacations.

I met a guy yesterday with a 2017 LT while I was in search of a L2 since I was down to 20 miles range. He was hogging the charger because he had 290 max miles range showing on his GOM and OVER 121k on the odometer! He said regularly gets over 300 in range and he always charges to 100%. I waited for him to finish for about one hour. After one hour, he was still charging trying to get that last 10 miles of range. I gave up and went to the next charger location.

Very rude of him to squat on the L2 for over one hour just to get 10 miles of range but also very informative to witness an owner with over 121k miles. He said he does not participate on this site so I can talk about him. LOL!
