His issue was quite obvious in that its now November, Winter is just around the corner, and EV ranges tend to go... well, you know. So I started asking questions and
1) He did not have LEAF Spy but that was not a game ender.
2) He did give a bare bones description of his drive (no distance mentioned)
3) He posted a screen shot of Trip A distance (which was reset) and the Battery SOC meter.
4) After asking him to post his trip computer a few times, he finally did but also said it had not been reset for the trip.
I get that he was probably new but at the same time, he was completely unprepared to make a trip that taxes the range of the LEAF. Having LEAF Spy makes it all much easier but if you don't have it, don't fret. You still have the car and despite its instrument's huge drawbacks, you can still find out just about all you need to know anyway.
Details are still sketchy despite an extensive back and forth conversation on Facebook, but it would appear that he arrived at his destination with 1% then QC'd to 90% and then posted his dilemma online. As a new EVer, he was simply unaware of how the changing seasons affected his range. But even seasoned EVers get caught short when underestimating the range loss caused by the weather that day. Wind, water on the road, temperatures, climate control needs, etc. They all make a difference.
Normally, this is where I say "Get LEAF Spy!" but if you don't have it or you ordered the parts and chose the free Amazon shipping option and their "5 to 8 day" window balloons to 3 weeks, here is what you can do in the meantime.
This is my Drive Computer screen available on the 2018 LEAF. When cruising around, this screen occupies the dash 95% of the time. This displays the 4 parameters shown above and each parameter can be reset individually thru the menu but in my case, I simply press and hold the OK button (center button on 4 way nav panel, left side steering wheel) a few seconds to reset the entire computer.
All this is part of my logging process that has existed with minor changes since getting my 2004 Prius June 30, 2004. I logged daily driving stats along with fuel/maintenance costs to determine my overall TCO. I reset Trip A daily, Trip B on the first of every month.
Doing this daily made it easy for me to customize my LEAF Spy settings. I use 5 basic settings for estimated ranges. One for Summer (4.7 miles per kwh) and 4 for Winter. This gives me an estimated range based on my selected miles/kwh setting. As I drive, I monitor the Drive Computer to see how well my prediction is working out. Sometimes I have to adjust my driving and speed to make my goal but that also means that sometimes I have extra which means 70 mph instead of 60... :)
