Electric Toaster
Member
Hello everyone,
My partner and I bought our 2013 Nissan Leaf with around 20k miles a few months ago through a private sale. The car has both charging CHAdeMO and J1772 charging ports. We really love this little toaster, but it has developed an issue with charging.
The car charged up to our 80% target SOC fine for the first few weeks of ownership, but then started to fall short of that, consistently stopping around 65%, and would display an error icon on the dash upon startup. The scheduling/timing function was not active and the issue was reproduced on both our level 1 and level 2 J1172 chargers. The CHAdeMO fast charging works reliably though.
I read online that our cars are very sensitive to issues with the 12V battery, so I checked its voltage. With the car turned on, I was reading around 12.5V. Coming from ICE land, I was expecting to see 14V or higher. The battery was also a few years old, so I replaced it. I later load-tested that old battery and found it to be in pretty healthy condition, though.
With the replacement 12V battery, the car charged flawlessly for another couple of weeks, but then the same issue returned. I added a battery tender to the 12V battery, which we plug in any time the car is parked. With the battery tender, the issue once again went away for a few weeks, but is now back again, but more sporadically this time.
I downloaded leafspy pro and read the codes following the most recent failure to complete a charge and there are a variety of error codes. Some are about unexpected voltages or currents in various systems. I've attached the screen shot.
I've searched around the forums via google, but have not found this exact issue. Any insight about what might be going on would be greatly appreciated.
