2012 LEAF SL with 63,418 miles. Located in Albuquerque, NM. Owned since December, 2015. Warranty HV battery pack replacement 3/2017.
My Leaf Spy Pro, version 0.45.119 running on an Android phone. LELink 2 installed 10/2018 in Always plugged in to the port. No problems until now.
I haven't driven my LEAF very much over the last 14 months, just under 2,800 miles since 1/1/2020. Sometime during the last 14 months I started to notice that the screen, "Charging Power" stopped functioning. No magenta, no red lines. On the motor power/braking screen, I also noticed that the graph peaks started exceeding the boarders of the charts, which was a new development. How do I fix these two issues?
If one fix is to uninstall and then reinstall the app please provide the links to the previous posts/you tube pages where this has been laid out.
Up until mid-February or so, I didn't have any problems with the car sitting and not being driven for up to a week. I left it plugged into the 240vlt charger. Then we had a cold snap for a few days where the temps didn't get above freezing and when I tried to start the car, the 12volt had lost enough charge to not boot up the car. Put it onto the trickle/charger and after a few days it got back up to 13 volts or so. This happened a couple of times more when the car wasn't driven for 3-5 days. If I drove it a few miles every other day, I didn't have a problem. End of March, first part of April, a couple of times it lost enough charge over night that it wouldn't boot up. After charging it overnight I took the Duracell battery to the store where I bought it from and they load tested it . State of health was at 82% and since the battery was just three years old (3/18) it wasn't eligible for replacing. Over the last 4 days the 12volt has kept enough charge to start the car.
I'm taking the car into my Nissan dealer tomorrow for servicing not related to the charging problem and they will also do an overnight 'parasitic draw' test.
So my question is whether other folks have had charging problems when their LEAFS have not been driven regularly. While there may be something in the car draining the power, is it likely that my LELink 2 is not working?
Thanks in advance for your help.
