Haven't watched more than about 1 minute though. What's the gist? DC FCing is slower on the 40 kWh than the 24 kWh pack? Or, it gets throttled much earlier? I saw the bit about how he was estimating that a former 48 hour trip on a 24 kWh Leaf w/33 DC FCs he estimates would take 5 or 6 hours longer on a 40 kWh car.
I skimmed a few pages. Are there any actual battery temp readings from Leaf Spy? The graphs are pointless unless we know what they represent.Eddiec said:Forum posts with some data and/or pics

The '11 thru '17 Leaf has a crappy temp graph. I believe these huge overlapping ranges apply from '11 thru model year '17: http://www.electricvehiclewiki.com/Battery#Battery_Temperature_Gauge. It's pointless, at least from my experience w/my '13. MUCH better to get actual battery temps from Leaf Spy.

24º C - 45 kW
30º C - 39 kW
36º C - 33 kW
40º C - 28 kW
43º C - 27 kW
48º C - 22 kW
All the tests were done, while outside temperatures were still quite low, around -5º to 8º C.
So, I wonder what will happen in summer, when environment temperatures go up to 30º C and more.

Nubo said:Very strange that the throttling happens after the first one or two QC sessions. Edit: I misunderstood. It's the 3rd or 4th QC in a day that seems to be the problem. So the early squawks about rapid heating seem to be borne out. Or at least what the vehicle considers to be rapid heating. I'd be interested to know the actual temperatures.
FYI; This sounds bad but puts it on near equal footing with the Bolt.
