Cool down high battery temperature faster using Tow/Haul mode 🌡️

[Grumpy2]

If my battery temp is over the mid-line, driving in normal or sport will take hours, if ever, to cool it down. Switching into tow/haul will get it back to mid-line in about 15 minutes.

Great News, thanks for sharing.

Based on how this appears to work, our problem of not having a "button" to pre-condition the battery (at least for hot weather) before DCFC on long trips without using the Ford nav system would be resolved... Love hacks like this

I’ve spent lots of time towing with mine, and I’ve been really disappointed with the inability to precondition. The truck doesn’t seem to care if I navigate to a DCFC unless the battery is over 93º, at which point it’ll engage the A/C compressor to chill down to about 90º and stop. Charge starts to throttle down to 100 kW around 97º, which doesn’t take long when you’re starting that high.

Most of my trips have been in tow/haul mode because I’ve got my camper behind me, and I’ve never noticed a difference in battery cooling. I’ve given up using the truck’s navigation because it doesn’t make much difference. I’ve pulled to the west coast twice, San Antonio once, and am leaving for Texas and New England next week.

I’m obsessive about monitoring my temperatures, and I’ve concluded that none of it makes a bit of difference. The truck does what the truck does, which really sucks for fast charging on a trip.

Only if you have selected a trailer profile in my testing, you can be in tow/haul w/o a trailer, ie. hauling a heavy load in the bed of the truck.

Sounds like my transporting my 4 ratchet straps around!

Checking in from Canada... Does it do the inverse for a cold battery, I wonder?

I'm assuming there is a temperature range the system calls for, as when I tested this a month ago it only seemed to bring the battery down to 95*F from the higher 120-130 after a DCFC session, but when I tried it when the battery was sitting at 72* to see if it would raise it to the 95* mark, it didn't make a difference and the gauge cluster showed it in the middle mark the entire time; but that might not have been low enough to trigger the system to heat the pack.
