Yeah. Made my day considerably less interesting though! I'm surprised this is even possible, but they didn't reconnect the in-vehicle HVAC temperature sensor, and also plugged in some wiring harnesses "backwards" or something, resulting in the A/C button inverting (light on means off), and the...

That sounds reasonable. I should have several more cold spells in which to observe this condition occurring at higher SOC's (in the above example it happened at ~45%), and perhaps resulting in both greater cell voltage differences and pack voltage fluctuations. I expect you're right that...

I'll read up on that; thanks. Wonder if the pack voltage out of range is sufficient cause for warranty coverage, or if that too needs to be when not under load. Next weekend when I have more low temps I'll be able to reproduce this issue at a variety of loads, and probably get the pack...

I agree, it seems like more than simply capacity degradation. There's degradation in several cells resulting in such high resistance that the car "fails" to perform a typical and expected function. Then again, the cells are still rather close in voltage under no load. I understand that's...

I got my car back from the dealer and was able to reproduce the issue once. As I mentioned in the OP, this is reproducible in ambient temperatures of 30°F and lower. It's now warmed back up until next weekend, at which point I'll be able to do more testing and try to raise some DTCs. Because I...

Could you elaborate a bit on this? You mean if the sun of voltages of the cells in a module is less than 5V, the module is to be replaced?

edit: nevermind! Off topic, but I didn't know this existed. Could you provide a list of other such rich documents about the 2013 Leaf?

I get my leaf back tomorrow and have LeafSpy in hand (plus a nifty plotting tool I whipped up in python). I'll share once I've collected and visualized some data.

Right, sorry. Just making sure.

I assume you mean specifically for the 24kWh battery pack, as the other curves here go well beyond 50% SOC at full charging speed.

I was thinking in terms of getting documentation going on their end, per @SageBrush and others' advice. I'm not sure what the content of such a complaint should be. My inclination is to compile a complete document with evidence and analysis to support my argument, but I'm not a certified Nissan...

Actually, I see that that DC charging behavior is qualitatively similar to the 24kWh curve here (https://support.fastned.nl/hc/en-gb/articles/204784998-Charging-with-a-Nissan-Leaf-e-or-e-NV200). Here the x axis is SOC, but in my plots it was time, so you have to do a little mental math to...

This is also evident in severely diminished DC charging speeds the one time I did a full DC recharge from about 12% to 90% SOC on a 50kW ChargePoint charger. I expected it to hum along at close to 50kW (or whatever the max supported by my 24kWh Leaf) until it got to around 80%, then decrease the...

Thanks for the ongoing discussion all, (though I realize you enjoy this stuff as much as I do) I love how much more freely I can imagine the dynamics of cell voltage and resistance as a function of temperature, load, and SOC as a result of your collective insight. You might be interested in a...

That makes sense. Thank you.

(I'm so glad I reached out. You're all awesome and a breath of fresh air.) Re. the low tire pressure @DaveinOlyWA. I think it's a bad pressure sensor. Comes on in the cold and goes away at over 50°F or so. When I check they're never low. @SageBrush: I've recorded my interactions thus far, but...

Thanks for the quick replies everyone! Not gonna lie. It feels really good to have people agree that is sounds like a voltage issue. I'm going to buy Leaf Spy Pro and a DTC reader and put together a proper case to try and both sway my technicians and the warranty folks at Nissan. The tech did...

Video of behavior where rapid discharge becomes apparent at 40s: https://youtu.be/dULaMW2cUXQ Rapid (reported) battery disharge in low-ish temps and moderate-high power output My 2013 Leaf @ 57k miles experiences rapid (reported) battery discharge followed by a "limited motor power" warning...

Can you elaborate on the wiring from the backup camera to the center stack? I've got a 2012 Volt that already has aftermarket NAV but I'd like to add a backup camera. Also, I have a dash cam in the front, and I'd like to split the signal from the backup cam to a secondary dash cam. This would...
