First bar just lost - 27.4k miles. SF Bay Area, and I charge to 80% nearly all the time. Not happy.
So you are getting home with about 7 miles range left, or somewhere between LBW and VLBW on a daily basis now? Are you typically driving 65 mph indicated mostly freeway for your commute?mwalsh said:And if all else is favorable (weather, pack balance, traffic, etc...), at 10 bars I can still get 68 miles* out of the car on my (almost all highway) commute. So it's still working for me, bearing in mind the commute is 61 miles. This winter will be interesting though!
*Better make that a theoretical 68 miles, based on Gid counts.
I noticed the same thing, though it wasn't apparent until after I got the P3227 update. Haven't noticed any significant behavior since the update 4 months ago and now (and lost a bar during that time).JeremyW said:I've noticed as I get closer to losing my first bar that regen is more limited at higher SOC. I was cruising this morning and I only had one regen circle at 191 gids! Battery temperature was 20 c. If I flog it on the freeway I typically won't get all my regen circles till nearly 50% SOC! Anyone else with significant capacity loss notice this?
From one of your other post, it sure sounds like you are driving it hard and fast (ie. 45-50mi @ 100%) or there is something wrong with your battery:tailgate1234 said:First bar just lost - 27.4k miles. SF Bay Area, and I charge to 80% nearly all the time. Not happy.
tailgate1234 said:I have been consistently getting 45-50 miles of range on 100% charge for 6 months or so now. I am in N. California so there are no extreme heat or cold issues that would affect battery life, and my LEAF still shows I have 12 battery segments remaining. It is taking only about 4 hours to fully charge from near empty battery to 100% full, and a little more than 3 hours to 80%. Something seems wrong here - either I have had significant battery degradation not showing up as reduced battery segments (seems unlikely because I am not in Arizona or a similar hot place) or the car doesn't seem to be able to accurately determine when the car is at a high charge or low charge state (seems much more likely to me). I am at about 20,000 miles.
Anybody experience this problem? My apologies if this has been covered elsewhere.

Used to always have 5 bubble regen on 80% charge until winter - now only 4 bubble regen until SOC gets down to 60-70% and then the 5th bubble goes on/off until I get down below 50-60% SOC when it seems to pretty much stay on, though available regen still seems to be less than before - typically about 5 kW less if looking at the energy monitor. I also notice more readily that regen capability seems highest between 25-40 mph or so and at higher speeds it seems to go down.
First capacity bar loss occurs around 55.5 Ah. You aren't anywhere close to losing a capacity bar.bowthom said:I don't get how we could do so well for 28 months and then have it drop like a stone. I'll be losing a capacity bar soon.
ON EDIT: The capacity however was 61.23Ah in july and shows 61.60Ah in October but GIDS and Health decline?
bowthom said:Hello,
I've been puzzled, Last April after 2 years & 2 months of ownership my Leaf showed 279 GIDs. In Aug it had dropped to 259. End of Sept it was 256. I had the LiBC and OBC reprogramming done 10/2/13. Directly after GIDs ticked up but have now fallen back to 260. The health figure has steadily fallen from 98.5% in April to 86.54% today with a little bump upwards just before the reprogramming on 9/30 to 94.01% when the temps fell.
I don't get how we could do so well for 28 months and then have it drop like a stone. I'll be losing a capacity bar soon.

mwalsh said:The conversation with my boss, requesting at least some charging every working day, wasn't supposed to happen for 5 years. Yet here I am at under 3 years having to go cap-in-hand. Not really acceptable.
mwalsh said:What I'm having a hard time with is the scoffing and sniping from those who, for whatever reason, never believed in my EV adventure. It bothers me personally, because I really did evangelize this vehicle and I'm having to eat crow. But it also makes me look like I don't have sound professional judgement, since one of my responsibilities is buying technology for the company.
Frankly, I really ain't happy about being put in this situation so soon.
mwalsh said:So it's already round the office that I'll be charging my car at work on pretty much a daily basis from now on (at least until I qualify for a pack replacement under the warranty). Yes, there is some indignity that I'm getting to fuel my car here. And many are assuming it will be for free, while I'm busy pointing out that I'll be paying for the electricity I use (unlike the guys who run personal refrigerators and coffee makers in their offices...but whatever).
I can take all that. What I'm having a hard time with is the scoffing and sniping from those who, for whatever reason, never believed in my EV adventure.

Even for me, at 41K miles and on the cusp of losing one bar, the range loss has been faster than we expected when we purchased the car. We just got new tires (just in time for the 4-5" of snow we got last night) which have further reduced the range. While I can charge at work in "emergencies", I'm not sure I can justify every day as such. My workaround is to use my bicycle as my "range extender" whenever I can. I often park several miles from work, get in about 25 minutes of solid exercise by biking the remaining distance, then shower at work. I shouldn't have to do this, but thankfully I've long been an avid cyclist and I enjoy cardio workouts.mwalsh said:And even though it's supposed to warm up again this next week, I'm very much afraid that this is a preview of things to come over the winter.
I'm impressed that you'll probably manage to do double the miles that I have before losing a bar despite all your mountain driving... I bet you make it close to 50k miles before losing a bar. Those cold mountain nights have really helped extend the life of your battery.abasile said:Even for me, at 41K miles and on the cusp of losing one bar, the range loss has been faster than we expected when we purchased the car.
With respect to the bolded section, all manufacturers should do so, but until there's an agreed upon and mandated standard (70% of original capacity? 80%?) it ain't gonna happen.drees said:Nissan really needs to sell the car based on it's end-of-life range/capacity. Basically - if you need to charge past 80% regularly you probably shouldn't buy the car. And they really need a charge slider like Tesla - so one can easily charge to anywhere from say 50-100% in 10% increments. With that level of control - you might even sell the car based on the range on a 70% charge.
RegGuheert said:Was that after the reprogramming?LEAFfan said:All the cars I've tested here and it has been many including my own, lost the first bar around 80-81% Gids. I already tested recently a 3-bar loss car that is around 65%. I believe they will lose their fourth CB around 61-62% Gids based on the % of the first bar losses.
That would be nice, but based on the capacity that my car is reporting (55.45 Ah), the first bar is due to disappear any time now. Of course, the bottom line is that the range is down. We're thankful to be able to QC at Fontana Nissan and L2 at Metro Nissan (Redlands) when we need to!drees said:I bet you make it close to 50k miles before losing a bar.
