I have just collected my ZS EV from the dealer following its first annual service. On the invoice it says they have carried out three software updates, viz. BMS Update, HV Fuse Update, and Drive Motor Control Module Update.
I know about the first two updates,but what is the Drive Motor Control Module Update?
Is this a new update?

Maybe to do with the regen? Been reports of much improved regen at high SOC. When car is at 100% Charge the regen is negligible. But with the Battery BMS update they've reduced used capacity at top end meaning the motor can regen into that spare capacity, presumably they have to update the Motor firmware though to use it?

I think the more regen issue maybe due to the latest BMS redefining the top and bottom buffer regions.
Is the motor control unit one the ability to charge your car whilst it is unlocked on AC charging?
That one came in around July last year so if you have not had any updates since then that might be it. Would have thought your dealer would have told you though.
