Sage Brush,
I never post kWh readings from Leaf Spy because they are based upon the scaling factor chosen by the user. I post the "Gid" value because Leaf Spy reads that number directly from the car. I personally have the scaling factor set to 80 watt hours per "Gid" because that was the value noted by Phil back in 2011 (and also printed in early versions of the service manual). I have a "Gid" meter that I assembled from a kit I purchased from Gary in 2012 so using 80 allowed me to directly compare readings from Leaf Spy to readings from the meter on the older cars. I used a Y-cable and kept both Gid meter and Leaf Spy running in the older cars. I don't know if the Gid Meter is compatible with the CAN Bus in the new car and there is no place to put it with the new dash/console design so I have not tried to use it. i kept the setting at 80 Wh/Gid with the new car so I can directly compare data with records from my old cars. For comparison, my older cars always hit LBW at 49 Gids, VLBW at 24 Gids, Turtle at 5 Gids, and Shutdown at 4 Gids (other cars may be different and less consistent because I always charged to 100% and discharged deeply so the cells were well balanced). The Gids at full charge for the 2015 were 282 or 283 when new and started to slowly drop after about 6 months. The Gids at full charge on the replacement battery in the 2011 started a little lower and immediately started to decline slowly.

The kWh, peak demand, voltage, and current measurements came from a revenue-accuracy smart meter on the branch circuit which supplies the EVSE.

Dave,
The SOC percent on the dash display did go to flashing --- after counting down to 1%, but I did not note the Gid reading. I know it was flashing dashes when power-limited mode (Turtle) happened at 9 Gids.

I would guess all the events are percentage based which explains why the hidden reserve grows as the pack gets larger but on my 40, the SOC meter goes blank at 25 or 26 GIDs or.... the same as VLB on the 24's. I thought that was interesting.

Now the dilemma was naming this event. I originally thought of Super Turtle but since there was no power limiting I decided against that as being too misleading although power limiting does happen before Turtle shows up.

So I settled on "SUCKS"

We made it by 7:15, so we had plenty of time to get to our show. We saw a production of Macbeth, which was very good, so I’m glad we didn’t miss the start. I’ll post more details about our drive down later, but the quick summary is we drove 65-70 the whole way, the battery got up to 114F, and charging slowed down to 30kW at our final top-up. Much better than previous trips!

Good job! I take it no major traffic issues then

Can’t wait for the detailed report.

We got back home last night, so I can finally write up our trip with our Leaf Plus. We've taken this same trip from Seattle to Ashland previously with a 30kWh and a 40kWh Leaf, and in previous years it took us almost 13 hours, mostly due to very slow charging.

According to Google Maps, with no stops or traffic our route should be 462 miles and take 7 hours and 32 minutes. We ran into very little traffic, and no broken or occupied chargers on our trip South, and reached Ashland in 10 hours and 38 minutes. On the return trip, we ran into rush hour traffic in Portland, and two of the chargers were already occupied by a Leaf when we arrived, so it took us 11 hours and 15 minutes.

Friday
Cruise control set to 65-70 for entire trip, except for short stretches in reduced speed zones or for traffic.

Thanks for the report. Would have been nice is some of those were 100 Kw chargers. Most of what has been going in around here lately have been the 100 KW variety. Although some are 25 KW single phase units in some more isolated spots with only...you know...one phase. :).

Agreed, Great report. What was your overall efficiency for the trip? Is the fast charger infa good enough that you could have done more 200 mile sections vs. 120-140 mile seconds and reduced the number of stops/charges?

Of the 3 hours in additional time, how much of that would you have normally had taken (we usually stop for a solid 90 minutes out of every 4 hours driven in an ICE)?

For us it would be more like 45 minutes of stops for every 4 hours of drive time. We have a chihuahua that needs frequent breaks. That and I think my bladder is about the size of the chihuahuas.
