Re: Any degradation statistics on 2013 yet?

Mon Oct 20, 2014 9:10 pm

My 2013 has a build date of 12/13 (*). I leased it on 4/14, almost exactly 6 months (and 4500mi) ago. Just this last Friday I had the best GIDs reading ever: 279. (thus, I'm still at 12 bars) I regularly charge to 100% (via L2 @ 6.6kWh), 5 days a week. I've done a total of 14 QCs, also.

(*) I would have thought they'd have been building 2014s by 12/13, but apparently not.

Here's hoping that my car stays at 12 bars, then!

Our MY2013 has ALWAYS charged to 79%, so I do not see this as an issue. We are at just over One year and 16,000 miles and the total Gids remains about the same as when new.
I'd love to be reassured by that, but have you compared your GID count with others? Your car may have been 'pre-degraded' on the dealer's lot.
Our Leaf arrived on the dealer lot early morning 9/6/13, fresh from factory with Aug 2013 Mfg date. We drove it away from the lot early afternoon. We had ordered it in July so was a long wait. We got our Leaf DD in December 2013. It has been monitored constantly since then. It is my understanding that some of the MY2013 Leafs showed around 260 gids while others showed 284 at 100%. At 80% charge setting the dash always shows 79%, and 209 gids. If there is any reduction in 16,000 miles it is only a couple of gids. We charge to 100% about once per week to keep the pack balanced.

Hope this helps.

AFAIK nearly all data are anecdotal. The most compelling anecdote that I have read on this forum occurred about 6 months ago. A poster from the SF East bay area (much warmer than SF, though not as hot as Texas or Arizona). A member of this forum who works at a large East Bay firm that maintains an email list of electric cars for scheduling purposes of the limited charging stations at work, sent a query to the list members. He asked for degradation reports from people who had purchased late MY2012 Leafs and early MY2013 Leafs. The cars were only a few months apart in age. Several list members reported significant degradation of their 2012 Leafs, none of the 2013 owners reported any degradation. I have searched for that post on this forum, but can't find it.

We have 2 Leafs, both made May 2013. One has 15k miles, the other 12k miles. There is no degradation as measured by LeafSpy capacity or GIDS. I frequently drive mine below VLBW and mostly charge to 100%. I haven't done any recent formal range tests, but I still have no problem driving from Palo Alto, over the Santa Cruz mountains-hiway 17 to Santa Cruz and back on one charge. 84 miles. Palo Alto weather is warmer than San Francisco, but cooler than the East Bay.

This information, along with the remarkable lack of 2013 owners reporting bar loss, lead me to believe that the 2013 Leafs do indeed have more heat tolerant batteries than the 2011 and 2012 Leafs.

I actually think they may have the Lizard battery in them, but Nissan didn't announce that fact, due the the bad publicity of the battery problem of earlier Leafs. In other words, the 2013 and 2014 owners are the beta testers of the Lizard battery.

2 LEAFS, bought 1 week apart. 2013 S for me, 2013 SV is wife's. Both manufactured May 2013. I lost first bar at 36,000. Wife still has all bars at 50,000.

The thing about my car is it charged to 80% for more than a year, then started stopping at 79%. That still sounds to me like degradation.

I'd guess it's possibly a rounding error in the software.

I'm not sure that the endpoint when you charge to 80% means a whole lot in terms of battery degradation. I believe that the car will be trying to charge to 80% of your capacity, whatever that may be. I.e. if you had 20kWh of capacity, it would charge about 16kWh, if your capacity dropped to 10kWh then setting to 80% charge would get you about 8kWh.

Your change is noteworthy, but I don't know that it really tells you anything about total capacity.

My 2013 (build date 5/13, delivery 7/13) has 12k miles and 2-3% degradation compared to a year ago. I've been using LeafSpy since Sept of last year and track my Ahr at least twice a month. I live 90 miles north of NYC and keep it garaged at night (charge to 80% most days) so the battery has been relatively pampered.

FWIW I've got one of the 'low Ahr' leafs where my new pack was somewhere between 60-61 Ahr and now it's about 58-59 Ahr.

I also have a 2013. We picked it up in March of 14, it started at 67.36 AH and 109.76 HX (didn't record GID's then) and at 2000 miles we were at 63.68 AH, 97.74 HX and 277 GID. Now at 6654 miles we are at 59.55 AH, 90.94 HX and 258 GID. Seems to be dropping fast... It is a pretty consistent drop over time, but seems to be slowing a bit.

We charge to 80% about 13 out of 14 days. Being in Green Bay, WI, it's not exactly warm, I have never seen the battery above 5 bars and is kept in an attached insulated garage.
