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?
