Battery overheating? during drive and charging

Summer recently arrived here in Chicago.

Recently I am getting lots of charging faults. The car will not complete the charging cycle, sends me a text stating
"NWI White Lightning had a fault while charging"
5 minutes later I'll get another
"NWI White Lightning's scheduled charge has not begun"

I go out to the garage and a very loud fan is running in the engine. AC???

Driving on a hot day with 20+ miles, I also get the orange wrench and the orange battery on the dash. Sounds to me like the battery is overheating. We don't have many EVs here, Our local Ford tech is submitting a warrantee to Ford to replace a cable. Sounds like he's way off.

Any suggestions? or links


2015 FFE - "NWI White Lightning"

Check coolant level.
Have dealer do a coolant system purge. Ask them to do it twice. This will get rid of any air trapped in system and if one of the coolant valve are not working it should show up while they are doing the procedure.

Hope this helps.

Update
7/5 Ford replaced my 110 charger under warrantee. It was causing a charging fault while the dealers charger worked fine. I never use this charger. I have a 220 in the garage.
While the car is sitting in front of the dealer. More warning lights go on. Back home in the loaner.
It’s about 90 outside.

Got a TEXT from my Ford mobile at 5:55 am “..scheduled charge has not begun”
Last night, the tech had taken the car home (20+ miles) to try to reproduce the problem.
When he returned to the shop in the morning, he plugged in from 5:49-6:18

Ford dealer called. My free loaner time has expired. Back to the dealer.
I convince the service writer the problem will be recreated, as it is 95 outside.
The car has a message: “It’s hot outside, plug in when you’re not driving”
(Plug in to cool it down??)
I drive the car 3 miles at 50+ and the battery and wrench warning lights go on.
Back to the dealer. The car is still sitting, running with the AC running and I get 3 texts in the next 10 minutes:
3:57 “…scheduled charge has not begun”
4:06 “… has a warning light on”
4:07 “… has a warning light on”

This has stumped a seasoned Ford technician. Fortunately, he has a ticket open with Ford. Hopefully, they can figure it out. Driving our ¾ ton truck is not good.

Not to be snarky, but your seasoned Ford Tech has or has not pulled codes from the vehicle?
You might want to consider looking at my post from the other day about "Something to Check on Your Car".
It could be that you have a similar problem with a falsely secured HV connector. Maybe not the one in the photos.
Maybe your problem is that the connector that carries the temperature signal is not properly connected.

He pulled the codes. Has Ford assisting. I have one of very few (3??) in NW INdiana. These techs don't see the EVs often. Hopefully he saw your reply.
They are charging the car and getting errors as we speak. Its 95 again here.

Thanks
