Battery Temp... with pictures!

[cowboys1870]

LOL, no.

Batteries get warm from charging and discharging, the BMS takes care of all the work, drive mode is irrelevant.

You should only see elevated temps if you're towing uphill in the heat.

You are incorrect.

My battery will sit a little warm, right of center on the gauge, in Normal Mode.

When I switch to Sport Mode it will start cooling the battery more aggressively, and always brings the temperature gauge back to center (likely wastes some energy).

You don’t need much imagination to envision Ford having Sport Mode pre-cool the system to prepare for heavy use.

Don’t comment if you don’t know what you’re talking about.

Also, it is very common to see the temperature gauge right of center (hot) if you live somewhere with 100° summers. The BMS does not always try to cool the battery back to center on the gauge (I’m sure it’s still within safe operating temperature).

Interesting, I haven't seen mine that high, even when it's near 100f outside.

Do you have the max tow package?

I do not. ‘22 SR XLT, no options.

95°+ sunny work blacktop lot for 8hr and mine will be right of center every time.

The gauge will stay put on my ~30min commute in normal mode, but if I switch to sport it will cool down to center within 5-10min.

A significant observation. Do you think your driving behavior is nearly the same, only the mode is changed?

Sitting in the driveway, Tow/Haul or Sport mode being on immediately kick the A/C compressor on and cool the battery, pulling 3-4kW.

I have a 24 lariat in Sacramento and when it’s 100 plus my battery temp is right in middle even when I floor it from stop light to stop light. It’s funny that my heavy truck is just as fast as my wify 21 Mach e GTPE

Regardless the battery normal temp tange is low middle and right. So why do you care if it’s a little to right ?

Does that mean we could switch to sport mode as a pseudo-precondition button for DCFC?

In the heat at least, yes. No idea if it also aggressively warms it in winter.

Same a @BSull. I believe the cabin AC pulled double duty tho. Did a test on my last trip. Diverting cooling to the floor will bring the battery temp back to normal range. I was able to duplicate the results several times.

I live in Peoria AZ too. Are you saying that diverting the AC to the floor will cool the batteries? I'll have to try that because my battery temps have been high all summer.

It’s a guess. With the max tow package, there’s a second cooling system for the pack. That said, I recall reading somewhere in the manual that you may feel cool air at
Your feet when the truck is working to cool the pack. It has appeared to work for me .
See ya @ Lake Plesant sometime

600 mile round trip yesterday in my ‘23 SR Pro was the first time in 16k miles / 19 months that I’ve seen the battery temp gauge budge from dead center. Ambient temp was around 100 degrees and I was DC fast charging at a Tesla Supercharger. Temp went back to the center after driving for a while. Supercharging was slow at two different Superchargers, starting out around 150 kW but dropping to about half that fairly quickly, both times starting at a fairly low SOC. I had somewhat better results at the same two Superchargers on the return trip, when it was a bit cooler, so I’m assuming that earlier either the Supercharger or the truck reduced the charge rate due to the heat. My previous Supercharging experiences were similar to other DCFCs, speed-wise.
Earlier this summer on a desert road trip in my Tesla Model 3 the heat (115+) didn’t seem to affect the charging speed at all, which was surprising. I did notice that the cabin A/C was having a hard time keeping up while the car was charging. I’m assuming most of its cooling power was focused on keeping the battery cool.

I have noticed that when we take our Model Y to superchargers here in Vegas, that when the cable/handle is hot when I plug in the charge is going to be slower. The charger near where we live is a popular one, so it sees lots of traffic. My guess is the heat is partially due to the ambient temp, but also partly due to the previous car getting the handle warm.

Supercharger speeds on the Lightning roadtrips through the Mojave have always been good speed.

Just a comment, the Lightning does not charge faster when you arrive at a low state of charge like a Tesla does. You’ll generally see your best charging performance if you arrive above 15%. On road trips I target 20% for each stop and generally charge to 79% each stop and I arrive on the high side of my plan. Letting it drop low in the pack just seems to get me a lower average charge rate.

You can do the wet towel trick to speed up charging.

I have a small battery powered clip on fan, that would probably do the trick too
