I do the 120 volt at home with factory cable, it charges at 5 miles per hr of charge. I use my trip Meter to compare actual driving distance with guess o meter. I then drive to a location at work with 240 level 2 charge.. I reset my trip odometer and compare my return trip home of 16 miles. The guess o meter drops from starting number to around 20 miles less for trip, therefore showing usage of 4-5 ;miles more than same trip using the 120 v charge.. even tho 240v charges more efficient (15 miles/charge hr) it seems to use more mileage than 120v charge, I just thought the quicker charge causes a higher temperature charge in a shorter period of time... Also of interest is that of you put transmission in B mode, it will Regen more aggressively and can actually add a few miles to your trip at various stops

Some of what you are seeing is that it takes more battery energy to get home than it takes to get to work. I suspect some of that extra battery usage is due to additional load on your air conditioner to cool down the hot cabin after being baked in the Florida sun all day.

Do yourself a favor and get LeafSpy so that you can accurately monitor battery capacity (aHr) before and after the trips both ways. It will also allow you to accurately estimate range. You will need an iPhone or Android phone and a OBDII connector.

With LeafSpy you can also monitor watts used for the AC.

Here’s a screenshot of LeafSpy I took on my first 2016 Leaf. I’ve circled the aHr capacity after charging.

I haven't read this thread carefully, but as almost everyone has said, IGNORE THE GOM! https://mynissanleaf.com/viewtopic.php?f=31&t=11777&p=271853&hilit=chasing+tail+award#p271853 is still true. Also, looking at how much the GOM goes up by charging on whatever is useless.

Before getting Leaf Spy and a compatible OBD2 dongle, instead look at the starting and ending % state of charge on the center dash display. Also, you may as well reset the miles/kWh display at the beginning of each leg of a trip. Make a note of what those are after going one direction then the other.

You may have a slight elevation difference between the two end points. Use Google Earth Pro (https://www.google.com/earth/versions/#earth-pro) to find out. See https://priuschat.com/threads/google-earth-can-give-you-an-elevation-profile-of-a-route-between-2-points.100653/. As I said there:
"It also confirmed my suspicion about this one expressway having a gradual downhill slope when I go in a certain direction. When I go in that direction, I seem to get much better iMPG values than in the opposite."

iMPG = instantaneous mpg
 
Thanks for your replies I do believe there's a little better difference on the AC going home going up to speed 2 versus speed one, as I'm coming to work earler that seems to make a little difference but it seems to be evening out more on the 120 versus the 240 charge on the way home with the same speed distance and route.. thanks for your input you are right the gom sometimes goes up as you're driving and then goes down to compensate it really is a frustrating piece of technology but thats Nissan's deal I guess LOL thanks for your help guys appreciate it
 
Again, ignore the GOM.

At minimum, look at the % state of charge display and may as well reset the miles/kWh display at the beginning of each leg of the trip. Use Google Earth Pro for computers to see what the net elevation change is between your two end points.

I've had the GOM start out at 80 miles and after driving 8 miles, it's gone up to 88. If I get on the freeway, it drops by say 2 miles by every 1.x miles driven. If I go up the steep hill that his highway 17, it can drop by 40 miles after having driven 10.
 
The above isn't great since the bike route may be very different than the car route. For example, it's illegal to ride a bicycle on the highway and thus my test of home to work is totally different by bike vs. car.

That said, at least the end points are the same so maybe it's close enough?

If you really want the elevation profile at specific points on a valid for a cars path, then one will have to bite the bullet and install the app.
 
Or use ABetterRoutePlanner. After you plan a route, click on the path and it will show you an elevation burndown (it might only work if you are logged in).

Interesting... never heard of it before. It has my street but the zip code is wrong. There's an extra digit so the zip code makes no sense.
Source for map is https://www.openstreetmap.org/about

You could edit and fix this.
