Jim, there are two questions:
1. When will the support for the new Nissan Leaf be added, with a battery of 40 kWh?
2. Will there be full support for Tesla Model S? Why is this trend not developing? I mean the TM-Spy program.

Yes on #1. check forum, he has already started a thread for 40 kwh pack. As expected since sales won't start until Jan 23, there is not much activity there yet.
 
^^^
'18 Leaf has been on sale in Japan since October 2017.

As for TM Spy, there are threads like https://teslamotorsclub.com/tmc/threads/using-tm-spy-to-see-model-s-data.63051/ and https://teslamotorsclub.com/tmc/threads/helpful-links-to-tm-spy-threads.71717/.

Thanks for the link. Based on post #17 (Jim - LeafSpy), the output resistance calculation from the graphic confirms that Tesla's
output resistance is about 77 mohms versus the Leaf's of about 60 mohms at about 75F. Again, given that, the Tesla battery will
develop more internal heat than the Leaf's at the same moderate speed, i.e. more vehicle weight & more internal resistance.
Under the conditions shown in the graphic, the instantaneous power is about 130kW for 4 seconds (energy - 560kJoules)
 
It's Jan. and I lost another 12 GID's last month. 38083 mi. 53.86AH 67.77 SOH 59.24Hx 246 GID's at full charge. Still showing 10 bars but I expect the 3rd bar to drop any minute now. At this rate I might qualify for a replacement by April. Certainly by June at the latest.

The just released iOS version (Dec 19th) of LeafSpy includes support (with some limitations) for the 2018 Leaf (40/60 kWh batteries).

The latest Android test version also includes support for the 2018 Leaf. Still working on updating the Help which takes me some time to do before it can be released to all but the code will be the same. Anyone with LeafSpy Pro can install the test version by just going to this link.

I am tracking pretty close to yours. 54.17 AH 68.16 SOH 65.23 hx 243 GIDs 14769 mi. Still 10 bars. Cool December has halted the drop for now.
 
Dropped the 3rd bar today. 54.24AH, SOH 68.24%, Hx 59.68%, 38475 mi. 73 L3, 727 L1/L2. Nissan did the battery check just last week and according to them it's in excellent condition. I just completed my usual 55 mi. commute today and arrived home with 13% charge left and 9 mi. left on the GOM. Pretty soon I'm going to have to charge out in town every day or risk not being able to make it home.

Pathetic, that is significantly worse even than a typical 2011 Leaf. It just doesn't bode well for the 40kwh pack.

No, indeed. Given the low NMAC residual, I would encourage anyone considering buying a 2018 Leaf to lease one, instead. I for one am going to try to get them to raise the residual enough to make it less painful if I turn the car in.

Why not just wait for the 2019 Leaf? Will be so much better and won't have a battery that's total garbage!
 
Feb update on battery stats. Actually there's been almost no change from Jan apart from dropping the third bar in early Jan. Mileage stands at 39550 mi. 52.81 AH, 246 GID's, 67.70% SOH, 59.15% Hx. I'm now charging the battery at every opportunity and keeping the battery at full charge overnight in hopes of forcing the fourth bar to drop. Doesn't seem to have made any difference though. I'm starting to think that battery degradation is only a function of time and temperature. If true it doesn't bode well owners of 30KWH cars, Everybody is going to have replace their batteries before the warranty expires and some of us are going to do it a couple of times.
 
March update. 244 GID's at full charge. 53.13AH SOH = 66.85% Hx = 58.50% 40700 mi. 86 L3 charges. 778 L2 charges. February saw a small drop in capacity but the the biggest difference is in the L3 charge rate. Lower initial charge rate (85 Amps vs 106 Amps when new) and faster tapering of charge rate as it charges the battery. On a L3 charger, charge rate starts to taper off at about 80% and by 90% is down to 16 amps or less. I can no longer get to a full charge in 30 minutes even with a 50% charge when I start. L2 at home charges to 100% no problem. All the cells are in good balance (15 mv typically) so there's no bad cell causing this. I have to think that the BMS is limiting the charge rate.

I'm just above the range to lose the fourth bar. As the weather warms up here, I expect to lose the fourth bar in April or May. I'd be surprised if it holds out until June. So much for it being a 100,000 mile battery. As it stands now I end up having to stop somewhere 2-3 times a week to add enough charge to make sure I can get home safely.

What's the total pack voltage when it starts tapering? It should be over 390V, probably 392-396V or so. I would guess that it's the pack's internal resistance which has gone up and is limiting the charge rate.

The internal resistance on the 24kWhr battery is about 60 mohms (.06 ohms) at 25C. So at 100 amps
charging, the voltage drop is only about 6 volts. Since the 30kWhr battery will have a little lower
Internal resistance, it's voltage drop will be a little less at 100 amps.
 
Those resistance values are for discharge and assume a new battery. We're talking about a 30 kWh battery that's lost a lot of capacity, it's no surprise that it's internal resistance will be higher, especially while charging.

Not really! Here are my data from my '13 Leaf taken over the last 4+ years:

10/30 - 41,000 miles, 74 mohms per LeafDD, 23 deg, 66% SOC
12/26/16 - 43,000 miles, 110 mohms per LeafDD, 13 deg, 77% SOC
6/10/17 - 49,600 miles, 89 mohms per LeafDD, 19 deg, 70% SOC
7/1/17 - 51,000 miles, 62 mohms per LeafDD, 33 deg, 44% SOC
8/15/17 - 53,400 miles, 61 mohms per LeafDD, 35 deg, 57% SOC

Yes, as capacity is lost the resistance will increase, e.g. maybe 2-3X over its life. So when you start at 60 mohms when new,
maybe at worst case it's about 120-180 mohms. As the data indicate, the resistance hasn't really changed all that much
over 4 years, 60K miles, and a loss of about 12 Ahrs of capacity. Also remember, as the battery heats up, e.g. charging,
the resistance decreases.
 
Hi, I have a 2016 Leaf SV (leased in July 2016) and have about 22K miles. Last week, I lost my 3rd capacity bar!! I still have 16 months to go on my 3-year lease. Wondering what's the best option for me going forward. I didn't take it to the dealership yet to figure out what's going on.

I ordered "LELink Bluetooth Low Energy BLE OBD-II OBD2 Car Diagnostic Tool" and intend to use LeafSpy to get additional info.

My Atlanta daily commute is 60 miles and I go to work 4 days a week. I use a level-2 charger each night.

Thanks in advance for any advice!
