For me, it still seems to be the minimum battery temp getting over a certain threshold (around 77 degrees F.) that triggers the change from 5 to 6 TB.
Hit the button and you'll see all 4 temperatures (in Celsius) on the left. The graph next to the max temp on page 1 will also show all 4 temps relative to max... I think each pixel is 0.2C (or 0.36F)

There seems to be some fuzz.

Yesterday evening I saw the highest temps I've recalled while still seeing 5 TBs:

77.8 78.9 76.6 78.0

This evening I got 6 TBs:

78.7 80.2 77.3 79.1

Drove a few miles and saw one sensor go below 77F so I stopped and turned the car off for a minute, but still had 6 TBs:

78.2 79.6 76.7 78.4

Got home and the pack has cooled off a tiny bit more. Let the car sit for 5 minutes while I take the trash bins in, start up the car and see 5 TBs. But by the time I grab a screenshot a few seconds later it has gone back up to 6 TBs:

78.2 79.3 76.6 77.3

So that last reading is going to be very close to the threshold between 5-6 TBs!

Has anyone seen a change between 5 TB and 6 TB at any temperature much different (more than one degree) that 25 C /77 F?

I'm posting here: http://www.mynissanleaf.com/viewtopic.p ... 3&start=37" onclick="window.open(this.href);return false;

Interesting comparison: see 2nd & 3rd entry (just under 2 hours apart) from 6/18 and today's (6/23) from about 90 minutes ago. For 6/18 I was simply hitting the override button to take the car (parked outside overnight) from 80% to 100%, but it dropped 1 temp. bar. Today's entry has a higher MIN, but a lower MAX temp. (Sorry I don't track the middle two temps.)

Saw the exact same thing this morning.. As soon (within a second) as the max temp (T2 in this case) went from 24.9 to 25.0 the 6th TB lit up.

But I went from Min/Max = 75.8/80.9 with 6TBs in a matter of 109 minutes while charging from 80% to 100% and ending at Min/Max = 75.3/80.7 with 5TBs. (See http://www.mynissanleaf.com/viewtopic.p ... 3&start=37" onclick="window.open(this.href);return false;). True, the 6th bar went *OFF* rather than on, but there may also be a SOC relationship.

Had my first (and I think earliest) 7TB day of the year today; it was 100+ degrees in Dallas.
From memory, all my page 2 temps were 39.x degrees C (my page 1 temp was about 105 degrees F).
Between the time I parked after lunch and the time I left work, I went from about 96->102 degrees F (I didn't expect to hit 7TB today). I'm running my garage fan tonight and may go out and check the (LeafDD) temp when it charges early in the morning. It's supposed to "cool off" in the 90's next week.

Interesting.. 105F is 40.5C so maybe 40C is the trigger to turn on TB 7(??)
This morning I turned on the car and the max was 25.0C and had 6 TBs.
Later I turned it on again and the max had cooled to 24.6C.. 5 TBs.

No: I'm pretty sure the 7TB trigger is something <100 degrees F; like just above 37 degrees C. I'm sure I'll narrow it down eventually.

As soon as you notice the 7th TB, hit the button to go to page 2 on LeafDD and the 4 temps at the time you pressed the button will be locked on the display until you leave page 2...
