Charging Rate Limited in the Heat?

Yeah, I was being glib. Apologies to all.

In full disclosure, I had to look up glib. Need to brush up on my vocab, props.

Took another trip to El Paso this past weekend. This is the first time I've noticed the battery temp meter move prior to arriving at a DCFC. I charged 4 times, temps between 100 and 110. In every instance, the battery temp meter was to the right of middle while on the freeway. About 20min out from the DCFC (using Ford nav to the charger) I saw the battery temp meter start decreasing and about 10min out it was pegged in the middle. I didn't have an OBD reader to confirm, but if we can believe that meter then it is cooling the battery. I got slightly better charge rates than my trip over the July 4th weekend. Same chargers, same temps.

I use Android Auto and Google Maps which does not interface with the truck. I've been pulling into DC Fast Chargers with Battery Temps running hot. I didn't realize the truck would go out of its way to cool the battery prior to charging.

There's been some suspicion as to weather it would cool or not. This is the first time I've noticed it. If I had to guess, I think one (or more) of the recent updates either enabled it or fixed the display to properly show it.

I’m having the same problem. Max tow package, one battery meter shows heat right of center even at start up, mileage efficiency is down, and most importantly fast charging ramps down to 80/90kwh despite a low % of charge. This makes long trips unbearable. My dealer service center says the battery heat meter reading right of center on one battery only is normal, and that the vehicle is charging normally (despite their only testing it on their Blink slow charger…). I do live in Phoenix where the heat is regularly over 100, but the vehicle “fast” charged similarly on a trip to San Diego where the ambient temperature there is quite cool. Any help you could provide would be very much appreciated.

Hey! I can take a closer look into your battery/charging concerns if you'd like. Can you send us a direct message with your VIN and the dealership name/location? To send a private message, just click on our username and select "Start Conversation".

I tried searching and didn't see much; As someone enjoying heat indexes in excess of 115F, I've noticed I can't pull more than 60kW from any DC fast chargers. I saw that rate with some 85kW Charge point chargers, with EA 150kW stations, so on.

I imagine the truck is throttling itself to protect the battery but man this has really slowed down my cross country trip. I can hear the fan roaring, it's louder than my old Ranger in first gear lol.

Anyone else also experiencing this or is it something unique to me?

Recently I charged up my 2024 in my garage with my ChargePoint 50 at 48A The cord to the CPH50 were warm which is unusual. I have to say that I neglected to set the charging limit down. Meant to charge to 80% but it is set to 100% by default of course. So the charge was at 90% when I went out to check on it and it had been in the 90s the last few days. But what really alarmed me was that when I went inside my shop and felt the breaker box it was quite hot; the whole thing was hot including the cables running out the top. I would have thought the 60A breaker would have tripped. I do have a very old circuit panel box. Maybe I should replace it. But the cable coming from the charge point in the truck was warmer than I had experienced ever charging my EV6. But then the Lightning has the ER battery. I'll have to keep an eye on it and maybe charge at night if I want to do it at 11kW.
