Re: Battery Capacity Diminished 2016

Sat Apr 29, 2017 9:36 am

So I read this post and started thinking about my car, and fussed a bit, fiddled. There's a couple things I just don't understand I guess, namely the relationship between SOH in LeafSpy, GIDS and bars. I have 12/12 bars with 1800 miles as you'd expect, but even after a full charge last night and topping it off (just to be sure) this morning, my SOH @ 92% is not as high as I thought it would be. Perhaps you can help me interpret the results.

Car was built in 2/2016, ordered by Campbell-Nelson Nissan in Edmonds, WA and sold @ Tacoma Nissan. Delivered 12/29/2016 with something like 31 miles on it. It was raining. :)

SOH is the State of Health of the battery, and is not directly tied to the State of Charge. If the car was made in February and sold in December, it likely sat on a dealers lot at 100% charge for 10 months. Even in a cooler climate, that is still hard on the battery.

That's an interesting point, I hadn't thought of that, I'll have to do some research and get a spreadsheet going to see when I'll lose my first battery bar, it sounds like the pack might not be a long lived as I'd like it to be, BUT I will say I drive very short miles, usually 15 miles a day and then for errands on the weekends. About once a month I drive into the office (instead of taking the train) about 70 miles round trip. So it may not be that difficult to live with.

If anyone has other suggestions they are certainly appreciated.

Do you charge to 100% often? Always? If you just charged it full once, then it may improve with a few full charges. just make sure you drive it a bit, soon after it's fully charged.

Agree with this assessment 100%. This is why its critical to examine the car fax on these cars since you can pretty much tell how long they sat where.

I got a 2016 S30 (which they didn't start building until October 2016) in Nov 2016 so it insured that there was nearly no time on the lot. I am at 10,000 miles and still 100% SOH, 82.34 ahr, 363 GIDs (@ 77.5 wh/GID) Hx between 98 and 104. over 80 QCs. I have not lost anything yet. But again, built in Oct so has yet to see its first Summer and as you might guess with 10,000 miles in 5 months, it doesn't sit very much at any SOC!

Mine is also one that sat on a lot in Texas for almost a year. It is now at 70.75 AHr 89% SOH and 5175 mi. It has been fairly consistent for the last 2 months. When I bought it last Dec it was at 86% SOH, so it has improved a bit. It will be interesting to see how it does this summer.

I'm in almost the exact same boat (numbers in previous posts). That said, it's not getting worse and it's still way more than enough to get to work and back a few time between charges so I'm still happy with it. I do wonder if it'll make the 100k 9 bar warranty.

Good call, but no I only charge it two days a week, I think I just drive it so few miles that I may not be 'exercising' the pack well enough. I could just let it get below 25% and then charge it up fully on a evening before I have to drive a longer trip, or all the way into the office.

I dumped my LeafSpy data into a spreadsheet and I'm tracking it closely now vs. the standard battery bar breakpoints vs. warranty expectations here:

I'm not sure that you have to let the pack get that low before charging to 100%, but some people claim it helps. Anything from 20% on up is fine.

You are probably in better shape than you think. I still believe your car sitting on the lot all Summer hurt it but charging only twice a week will depress your numbers probably 10%. I actually tried this as well on my new car. I basically went on a 13 day stretch where I never charged it more than 2 hours and while only charging it 5 times.

My low water mark was 81.31 ahr, 97.01 Hx, SOH 97 on Nov 30th, Odometer 1011.3 miles. Today I am at 82.34 ahr, 102. 37 Hx (least important) and 100 SOH, Odometer 10,057.
