En Route Preconditioning for DC Fast Charging Does NOT Work

[B177y]

I did see my HVB temp get up to 78.8 yesterday while using Google maps to navigate to a Tesla DCFC with outdoor temp of 44 deg F. My HVB was 52 deg F at the start of the drive. 70 mph interstate driving. The coolant heater never seemed to come on and the air conditioner (heat pump) pulled between 7-8 amps consistently. Cabin temp was 68 on my side and 74 on the wife's side, auto low fan setting. First time I have seen the HVB temp warm up that high before a DCFC using CarScanner to monitor data.

I suspect 2024+ it works as intended, but 22-23 no longer does.

This was the first time that I have seen the HVB temp go above 58 deg before a DCFC stop. I did receive the Gateway OTA ECG-24.2.5.7 on Feb 28. Don't know if that changed anything?‍
