Temperature Bars On The LEAF

In 2018, the LEAF went to a slider like gauge for temperature bars and it works basically the same as previous versions with the same 12 segments, etc., but unlike my 24 kwh LEAFs, there is minimal overlap of the temperature ranges the bars appear and disappear.  They also are a lot more consistent at which temperature they appear and disappear...well, most of the time.

I did this the easy way of simply snapping pix as bars came and went (for the most part) so you could see for yourself. Below I will have 2 pix with the goal of showing both the lower and upper limit of each bar. Although you will see 3 temperatures, I am using the temperature # 1 (In portrait mode it would be the upper left reading) which is normally the highest, because of several examples of bar changes with matching temperature 1 but various other temps in the lower spots.   As we all know, when stationary, the 3 temps don't vary nearly as much as when we are moving. I once recorded a 24º difference from high to lowest during a cold day (40's) on one of my 2016's more "active" days AKA  starting a QC with 10 TBs!

Here the top temp is the same but 2nd temps are not hence my reason for using the
top temp only as a guide. There were several instances of this. 


There is a gap between bar 4 and 5. Due to limited exposure to lower temperatures of the battery, I am thinking both 4 and 5 are incomplete. I did see 3 bars only one  time during the Winter because the car is garaged so lower battery temps just don't happen that much.  Reality says that is not what people are wanting to see anyway and 6 - 9 are complete in that each was during an observed appearance or disappearance. The lower end of the 4th bar was recorded from the switch though.  In other instances where there is a gap from the high end of a bar and the low end of the next highest bar, we can assume the lower bar would have covered that gap.

4 Bars

39.8 - 47.1  º F

5 Bars

66.4 - 76.8 º F

6 Bars

78.6 - 95.8 º F

7 Bars

96.6 - 104.2 º F

8 Bars

105.6 - 114.8 º F

9 Bars

112.2 - 121.0 º  F

Interesting as I think the 9 Bar reads are an anomaly.  With no overlap anywhere else, the 9 Bar overlaps both ends!

10 Bars

119.2 - ???

Honorable Mention!

The upper range would definitely be just below 39.8º  and only got this due to a 36 hour power outage.

If anyone can fill in the gaps for 4 bars and under or 10 bars and up, please chime in!
