Extended Range Charging Error

[Picnics]

This is my 2 year anniversary with my 22 lightning with extended range. Lately it has been getting charging errors with the plug in wall charger at either 240v or 120v. At home in the heated garage it will occasionally get a charging fault usually when the battery is fairly low (below 50%)
now when I’ve been bringing it to my cabin in northern wisconsin it frequently gets an error when it is plugged into 120v. I know the charging rate is very slow at 120v. but it is still helpful for me to keep it plugged in especially when it’s 15 below like today.

It does charge fine at the fast chargers on trips.

Has anyone else been having this issue? The Dealer here isn’t very knowledgeable about these vehicles.

As an aside my work vans frequently get a fault on our pro charging station when the temp is below freezing.

Luckily my lightning pro that I use for work everyday has no issues. .

Are you using the same mobile charger? Might try a different AC charger to confirm it’s the truck and not the mobile charger. They are know to be a weak link.

The FMC and cold weather have been an issue.

I seem to have a problem with my mobile charger as well. Often the blue light on the front of the mobile charger turns half yellow and half blue. Not sure what’s up. I sure would like to know the answer. Also, when the light turns yellow, I can look at my phone and see that my charge rate drops down to about 3 kW From 6.0 kw

I have seen that problem when it was a heat related issue, warm at either end of the plug dongle. Make sure the dongle connector pins appear clean, and the dongle is plugged in all the way at both ends.

Thank you for sharing that information with me. I will check the connections next time I charge with my mobile charger.

I am surprised that we are not advised to use dielectric grease on our connectors. I wonder if that would hurt anything. I’ve been afraid to try it because I figured it might void the warranty or something crazy as it’s supposed to enhance electrical connections.

Dielectric grease keeps water out. It does not enhance conductivity of connections.
