Could you or someone supplement the instrument cluster images with one displaying the horizontal temperature bar on the 2018.
It appears to be different than the 2019. Thanks


Not familiar with any changes other than there are several different displays you can toggle thru. TBT; I don't see the need for having the temperature screen up all the time. Its worse than watching paint dry 99% of the time and it takes of 2 seconds to toggle to the screen if you want to look at it.

I generally have trip computer up all the time. The static displays for "most" screens has the mini power meter. If I were to want something on the screen other than what I see on the trip computer, I might want the instantaneous miles/kwh meter?


Is the 2018 temperature graphic segmented (vertical markings)? The 2019 temperature gauge is just a horizontal gray bar graph with two
red vertical lines at the right, and a short blue bar segment on the left.

You asked this a while ago, and I answered. There are no visible segments, but they are there. 12 bars like the old "gauge" but no dividing lines or marks between them.

PLEASE don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

So there're horizontal bars extending upward, versus only one continuous horizontal bar on the 2019? No red markings as the bars extend
upward to indicate excessive heat? So comparative discussions about one's battery temp becomes more subjective with the 2019s.

The 2018 battery temp... we'll say "graphic"... is a horizontal bar with a red zone on the right. You cannot see the segments in which it moves, but it does move in segments: it will always have its "end" in one of 12 locations along that horizontal plane. It sounds as if the 2019 is exactly the same.

Not familiar with any changes other than there are several different displays you can toggle thru. TBT; I don't see the need for having the temperature screen up all the time.

Thanks. That's excellent for anyone who wants an idea of what the actual temp is relative to the bar graph.
So the first red mark is about 120F+. The mid point is about 85F. The 2019 is the same as the 2018.

No prob.

To reiterate; the ideal batt temp for QC charge "start" appears to be about 86º F. Start a charge at a lower temp and you will see max charge rate but a lower knee. Knee is the point when amperage starts to drop. In a "50 KW" station (a bit misleading...) the norm is 120-125 amps.

Start at a higher temp and you will see less than full charge (lower amperage) at the start but the knee does move higher. However, the higher knee does not offset the time lost from slower charging speed but does make charging at 105º (about 35 KW) a bit more tolerable. sort of...

That's about a little less than 2/3 on the temperature bar graph, i.e. the battery is virtually in Tucson, AZ on a cool summer day.
Most all MNL members know what happens to Leaf batteries that are exposed frequently to that temperature.

Ahr: 110.9
SOH: 95.45
Hx:113.79
Odo: 7300 mi
QCs: 68
L2:178

Seemed to have dropped an entire SOH pct in the last 30 days with very hot weather (95+ for a week straight). QC once a day or less. Never got to red temp bar though.

Doesn't need to get there to be problematic, even frequent 110-115 F is to be avoided. Get LeafSpy to measure your temps after a QC.
