My new 2019 Leaf SV Plus will only go 150 miles before I get "Low Battery Warning" and it reaches 0% SOC after only 165 miles. This is driving under ideal conditions, non-stop, with tires at 39 psi, cruise set for 55mph, HVAC OFF, ambient of 80F, on essentially flat ground (the DelMarVa Peninsula is notoriously FLAT). After full charge the SOC reads 100% as expected and the GOM indicates 261 miles possible range. For the first 50% of SOC the car's capacity gauge operates relatively normal achieving anywhere from 1.9 to 2.6 miles per every 1% of SOC meter. After that point the rate of capacity loss accelerates down to 1.0 miles for every 1% SOC. Strangely Leaf Spy indicates that the battery still has nearly 24kWh of charge left even after the vehicles SOC gauge says 0% or less displaying just dashes (---). The car still drives well with no reduced power. I do get a "Low Battery" warning and a "Charge Now" warning but no turtle mode. So far I forced it to go beyond the 0% or "---" indication all the way to 175 miles but I'm worried about running out or damaging the battery. Leaf Spy still indicates 21.6kWh remain and 37% SOC. Somethings terribly wrong. Leaf Spy indicates my pack voltage is down to 347.3V with an average 3.618 cell voltage. Dealer ignores me and states he can find no issues. Can someone tell me what the pack voltage should be when down to 0% and what the individual cell voltages should be. I don't want to take them too low. The car was purchased as a left over 2019 just 4 months ago and has only 6000 miles on it.
"Big thanks for all the comments". I love these vehicles. This is my second Leaf. I just gave my 2015 SV to my daughter for her 16th Bday.
If you said your 2019 LEAF did this, I would think nothing of it because that is pretty much the range my 2018 "40" kwh LEAF got. Are you sure its a plus?
JK, 715 GIDs pretty much confirms it. You have a bad cell and it will only get weaker and fast so I would take it to a dealer. Doesn't have to be the one you got it from and get it fixed. You will want to take it in when the GOM is reading low.
How much is the delta of the pack (voltage high and low spread) at full charge (or near it) and how much is it at empty? Either way, the weak cell would be well away from the rest of the pack. It is defective.
After you get it fixed, I would suggest some surveys and ratings sites for the dealer that sold you the car.
