Re: 2016 30 kWh Battery data

Sadly, this is a known issue with the 30kwh Leafs, and you will likely lose that fourth bar this Summer. That's the good news! The bad news is that your free replacement pack will likely lose capacity just as fast, making buying the car off-less unappealing. To speed the loss of that 4th bar, try to keep the pack "Hot & Full" as much as possible. Then try to keep the new one "Cool & Comfortable" with less than 100% charges except as needed.

Apr status report. 241 GID's, 52.70 AH, SOH =66.31%, Hx = 58.08%. 42299 miles. 94 L3 charges, 812 L2 charges. With 3 bars gone already, I'm expecting to lose the 4th bar over the summer probably in July. Oddly enough, increased DCFC charging hasn't seemed to affect anything, nor has L2 charging every time I get home (in case I need to go out again that day). I figure the 4th bar should drop somewhere between 60-63% SOH. I am DCFC'ing 2-3 times a week just to be sure I can get home after running errands. DCFC now starts to taper off the charge rate over 65-70%. Also the charge rate starts a lower value (85-90 amps) then it used to (106 amps when new). At 90% the rate is down to 20 amps. This started after the 3rd bar dropped.

May status report. Still hanging in there with 9 bars but it can't be much longer now. 234 GID's 51.35AH SOH 64.72% Hx 56.86% 43750 mi. 104 L3, 849 L2. Range is down to 65 mi. I can make my daily commute OK but not if I have to make any detours. I'm DCFC'ing 2-4 times a week to be sure I can get home OK. Since my NCTC is still good and charging is free, it's more an inconvenience than a problem. If I had to pay for charging though it would be at least $50-75 a month for that much DCFC on EVGo.

I expect the battery to drop the fourth bar at 50 AH or so. End of May or sometime in June is my best guess. Too bad it will be another Crap battery from Nissan. I don't expect it to last any longer than this one so probably a third battery under warranty at 90,000 mi. I had hoped that this car would be good for 150K or more. Not gonna happen. I am going to have to replace this car by the time I pay it off and it won't be worth more than $5K when I get rid of it.

Can't believe your pack is still hanging on! You are at 40% capacity loss

Lost the fourth bar this morning! 44784 mi. 50.68AH SOH = 63.76% Hx = 56.08% 232 GIDs. 109 L3, 869 L2. Called the local Nissan dealer to set up an appointment to verify the condition and start the replacement process. Since I haven't heard anything from Nissan about an improved battery, it seems likely that I will have to do this again at about 90000 mi. I doubt that a replacement battery will last much longer than the original and with 55000 mi left on the warranty I expect to get a second replacement battery for free as well. That will take me out to about 135000 mi before I junk the car. Not what I was hoping for. I had always expected that the battery would fail under warranty but had expected it to last 75000-85000 mi before dying. Then a second battery would have got me to 150000-170000 mi and 8 or 9 years of operation. At that point, I could either sell it or put a new battery in it (hopefully, from a third party manufacturer) and go another 50000 mi or so. That doesn't seem feasible now with batteries that don't last more than 40K or so. I'll likely sell it off after 6 or 7 years for a pittance. Fortunately, I ought to have a much batter selection to choose from by then.

One must be wondering "what were they thinking?" when they offered a longer capacity warranty. I do suspect there was some sort of defect in a batch of early batteries, and the replacement pack will do better, which may be unfortunate as you might not be able to get another for free.

I'm not so sure about the defective early batch hypothesis unless it was the entire model year '16 and some (to all?) of '17 run. We are seeing signs the model year '17 30 kWh batteries aren't holding up that well either.

I pointed to a '17 1 bar loser at viewtopic.php?p=527514#p527514 in the Washington DC area.

I could see defective batches but not necessarily just early 30 kWh.

More likely Nissan thought that they had corrected the critical flaw in the packs or BMS for '17, but were mistaken. Cwerdna, do you know if the '17 BMS behaves any differently than the '16?

Other than possible charging/BMS practices with "some" regional distinctions, there is no evidence of any kind indicating a "line" of good packs and bad packs chronologically.
