Ok starting with some data....
346V star part...
This was to ~42kmph then back off with brakes (well there was a corner you see).
Torque drops off after this speed anyway.
and...
Torque remains much the same to ~70kmph. I'll get some more data.
Motor current sits flat at 97.xx Amps after ~10kmph.
I guess that is what we wanted to see !
40% regen is on for both runs.
How are we looking on the predictions ?
Now I need to stitch the two together with star delta switching.
Not that I think I can win back the <1.5 seconds, just that star takeoff on some hills would be useful.
