Your 70% charge is greater than my 80% which gives me 194 rated miles. I usually charge to 70-80% and drive down to 50-60%, rarely to 90%, and very rarely 100%. I'm not concerned but do pay close attention to the rated miles out of curiosity.

His 70% number has to be a mistake, as it's not possible unless he has a 300 mile pack. :wink:
Playing devil's advocate, if you're charging to 90%+ on a daily basis and are showing several miles higher than others who only rarely charge to 90%+, and you're only losing minimal actual mileage because of it (Islandbay only lost 1 or 2 miles after 34,000 on a 60kWh), then aren't you kind of getting more for your money? During trips where range is tight, your presumably can make it more comfortably since your pack is better balanced and displays higher, more accurate range. Having a lower, less accurate rated range reading (say that 10 times fast) wouldn't be a problem if you still were able to achieve the same actual range, but we don't believe it does, do we? I think it's something we all have to decide for ourselves, but there are merits to both sides.
Personally, I don't charge to 90%+ normally because I live in the mountains and don't get enough regenerative braking when leaving my house at that charge level, so I end up having to use friction brakes to keep my speed down, which I don't like doing.

This is more my situation. Until the charging situation gets better in my area, I need the most out my pack right now...all of it. I am hoping that in one or two more years more superchargers will be sprouting up in middle and northern Wisconsin that a little range loss will become less of an issue. So for me a well balanced pack is important, even if I might have a little more range loss when the car is at 100K+ miles.
Awesome post, thank you!
I've already done a couple of 100% charges and my rated range estimate has increased by 8 miles. That's enough to tell me the battery is fine and I'll be going back to my regular routine of charging to 50%-70%, which is fine for my daily needs.

100% cane out to 206 rated compared to 205 yesterday. that's on my new battery pack that has 4,300 miles.
My MS 60 has 12,000 miles and I only get 178Miles on a 90% charge and 198miles on a full charge. This is a bit disappointing. I tried to reduce the charge amps from 40 to 20 hoping it would gain me back some miles. Not luck still at 178.
Is this normal? I would love to know. This seemly happened overnight as I would normally get at least 185 on a standard 90% charge.

Interesting article regarding charging of li-ion batteries in PC World. Here is the link -

Just another data point - MS60 32k miles - been charging to 90% past few days and range has increased from 166 to 171. Will likely continue doing this for a few more weeks then will go back to my normal regime (50%-70%).
This article is much more informative: Green Car Congress: Study finds rapid charging and draining doesn't damage lithium-ion electrode as much as thought

It's has been normal for my car for at least a year or more. My S60 has 18,000 miles and gets 176-177 miles on a 90% charge.
You guys will need to charge to 90% (or more) every day for awhile to get the miles back.
What about NOT decreasing rated range?
While my daily 90% charge level has dropped from the original 242ish that it started to around 231, and my "usual" range charge has dropped from 272 to ~258 miles, what I've found, at 39,500 miles, is that after a long trip and a full charge (allowed to range charge until the charging actually completed that hour-long last minute) that my range numbers improve dramatically, and they seem to be real. These photos are from this weekend. I range charged to 258 miles prior to a trip to St. Louis (about 225 miles all interstate), arrived with about 8 miles left, charged to about 80% overnight then topped up yesterday afternoon and hit 273 miles rated! Even my 90% rated range has increased back into the 240s it appears.

That's amazing! I never saw anything above 264 or 265 on a Range Charge even when the car was new. It sounds like your miles came back fairly quickly (i.e. no need for a month+ of 90% charges like others are suggesting). I assume you also have an A-pack battery???
