As everyone whose experienced SpC very well knows, the taper is the killer. Very rarely is a rate of 100 kW maintained after 45% and after 50% the rate drops like a hot potato. Seeing a lot of variation as to when the taper begins on different cars under different conditions has me thinking as to what the best explanation for this variability is.
I'm pretty certain it all boils down to pack temperature. Some cars cross over 90 kW before 40%, others maintain it to nearly 50%. I guess those who sustain higher current draws later into the charge cycle must have cooler pack temps.
So now to "chill mode." As I'm approaching a SpC, let's say 5 miles out, I'd like to issue a command to pre-chill the battery and redirect cabin resources to the main battery if necessary. My thinking is that this increases the thermal buffer and would thus allow the pack to better handle the initial burst of 90/120 kW supercharging.
Any thoughts? Would this improve SpC measurably? Would anyone like to see chill-mode in a future release?
