Tesla Motors Club

So we went on medium length road trip on the weekend. I left the house at 100% charge from the triangle area and my garage was about 55 degrees when i left going by the temp the car displayed when i left. shortly into the the drive i had full regen and the on route battery warming didn't really pop on until about 15 minutes before we got to the supercharger on route. When I plugged in however at about 25% charge i only pulled about 100kW. We had driven a little over 2 hours at interstate speed, had about 15 minutes of on route warming and initially left with a battery at 55f. IMO it seems like we would have a plenty warm battery for full speeds. I tried 3 different stalls as I was the only one charging and they all had about the same speed. After I landed on the 3rd one and decided it wasn't the stall another 3 pulled in, dual motor, and plugged in and pulled 145kW right at the start.

On the way home, inverse of the trip we started off with a very cold battery, about 25f, and drove for a little over an hour before we got to the supercharger. However, this time the on route battery warming kicked in almost immediately and was on for over an hour before we got there. Again however, the car only pulled about 100kW at about 25% charge.

So my question, any thoughts on if the car is smart enough to start battery warming earlier in a rwd than an awd since it, from what i've read, has about half the heating power? I have a fairly early model # and I know there have been some charging pin updates so i'm going to get those looked at as well but just seems like it must be more temp related since we've never had issues chaging before unless it was cold.
