Yeah, but they're talking about only DCFC, while the OP specifically mentions L2 charging. DC chargers tend to be flaky and have compatibility issues across various brands, so I don't find it too surprising when there are issues there. But J1772 L2 charging has been solid for over a decade.
I...
Can you record a video of what you're experiencing?
Strange that it will charge fine at a dealership, but nowhere that you try.
But also... how did you manage to get 29,000 miles on a vehicle that doesn't charge? Is this just a recent development, and you had no issues charging before it started?
I just bought my F150 Lightning. I've got a OBD reader on order and I plan to start off with some software updates when that arrives. Might get some floor mats in a little bit. Still learning about the truck.
What kind of outlet are you using? NEMA 14-50?
The EVSE itself can go up to 32 amps.
A (properly-installed) 40-amp circuit should be able to deliver 32 amps continuous (80% rule).
Does this mean that the truck itself is limiting the draw to 24 amps? If so, it might be detecting a voltage drop...
