When I got my leaf 7 months ago, it would charge at 6.6kw as measured by the ChargePoint charging stations I use at my work. After about 2 months, it dropped to about 6.3kw or less and I have seen it go below 6 well before the battery is near full capacity. I see the car ramp down the power during the last 2% of the charging cycle, but this happens throughout the whole charge regardless of how low the battery is when I start.
I have tried multiple charging stations around town with the same result. Now it will only charge at 6.3kw or less. The decrease in charging rate coincided with the weather getting colder, so I assumed it was a function of things being cold and slowing down. But now the temps are back in the 70s and the charge rate has not come back up. The dealer checked the vehicle yesterday and said it did not have any stored codes, so they do not see a problem.
Has anyone else experienced this? Is this an indication of a potential problem or is it within the tolerance of the on board charger?
Car is a 2016 SV with a little over 3,000 miles on it.
