@jbuntz your post at https://www.facebook.com/groups/nissan.leaf.owners.group/permalink/2016892475048250/ showing observations the QC rate may have been reduced with the update is very interesting. Has anyone else here had the update and can confirm rates vs temperature and SoC?

Did the first QC since the update. Didn’t notice any change in behaviour but the temperature was only 6 bars and I only charged to 84 percent.

Other than the higher GOM numbers still the only change I have noticed is 4 regen bubbles at 94/95 ish percent rather than 90 percent.

Can you estimate how many miles you can drive between VLBW and turtle ?
I presume it is off the highway ;-)

I did not make any notes on the miles to turtle either way, but before it seemed like I would have to make several laps around the neighborhood to get down close to turtle. This last time one lap was good enough. One lap is about 4 miles at 30mph.

So charge speed, ramp down SOC, etc was the same? Do you have LEAF Spy?

So no to the Leaf Spy and I disconnected before any ramp down would have happened. We were charging for probably no more than 15 minutes.

Sorry couldn’t be of more help.

@rcm4453 given you are in MN, like me, and have lost bars already on your '16 Leaf I will be super interested in your analysis as well.

Charging to 84% you would have seen the ramp down unless you were on a 25 KW station but w/o a monitoring app, it would to hard to tell unless you were a station like EVGO that displays amperage during the charge.

Update on new battery after one month. 82.09 AH 363 GID's, SOH 103.20%, Hx 96.82%. 46966 mi. with just over 2000 mi on the new battery.
I had the software update done in late June but it appears that it was already done when the battery was changed. I haven't needed to to do a DCFC yet so I can't comment on charging rates with the new battery. Only real difference I see is that some regen is available at all times. I get one circle of regen available by the time I pull out of the driveway and LeafSpy says it's working. 3 circles by the time I'm down to 97% and all 4 by 94-95% down.

Battery health has actually improved slightly over the last month. I suspect that is due to the BMS learning the new battery. I expect it to take at least a year to see if the software patch actually does anything. I'll keep posting periodically for everyone's benefit.

Lithium Ion Batteries do "grow" in capacity when brand new and are exercised by use. The growth period is relatively short, you are probably close to the zenith right now.

Hope the new battery serves you well.

I know range is a touchy subject, but are you getting a feel for range with the new battery?
