Normal for power to slightly de-rate at 48F?

[lightspeed]

Curious,

It's not very cold where I am, but sometimes in the morning the truck shows 95% power when charged around 50% or less.

I checked with OBD2 reader and the battery temp was around 48F.

Do you guy see a slight de-rating of power even at this relatively modest coolness?

It's not a problem, more of a surprise.

I saw something similar (93% power) today with 44% battery remaining and 46 F outside after being parked in the sun for a few hours.

Yes, preconditioning eliminates that though.

I think it is more about percentage remaining And temperatur. Anytime I’m below 50% it drops the power but more so the colder it is.

These numbers seem normal from my experiences, last night coming home from a 190 mile road trip, I stopped at the DCFC to top up from 13% to 90%, outside temp was 32 °, I was seeing power output limit around 80%

BTW, the charge terminal was acting weird like it was Friday night, on screen display and app froze after initialization ~3 minutes in to charging session, but I was getting 140+ peak KW for a period, quick ramp up due to preconditioning the battery by choosing my favorite DCFC location.

I wanted to roll the dice, may be another free session due to software issues????, but snake eyes for my the 63 minute session, it yielded 107 KWH for an after sales tax cost of $16.10, still much cheaper than at home overall, the final couple of KW were trickling in at ~23KW to get me to 90%


I didn't get a snap shot of the output limiter though, here is the charging summary, but after charging the battery pack was nice and warm and had 100% output capacity
