Does anyone have technical details of how the coolant system works for the battery, power electronics, and motor(s)?

I'm particularly interested in the heat pump and how effective that is at keeping the temps down.

  • Is there a separate coolant compressor (AC vs. battery cooling)?
  • Can a typical 60,000BTU system really make much of a dent in the temperatures?
  • Can the pack and motor be "pre-chilled" for 0-60 launches?
  • Do diagrams of the system exist?

I think it would be great to be able to pre-chill the battery. Increased thermal buffer for SpC or hot days.

I'd like that feature, it shouldn't be too hard to do, if nav destination is a SC and SOC < x then set battery temperature set point lower y miles before arrival.

I'd be happy if they just made it possible to pre-heat the battery on cold mornings so I could get full regen. I know pre-heating the interior kind of helps, but it's a pretty mediocre workaround.
