Sorry for basic question:
I understand how the motor controllers, when they're rated for say 20A, will PWM the current coming from the battery pack to make an "average" current rating not to exceed the 20A.
But if you're looking at the more instantaneous current demand : how is that being limited?
Because in general, for a short period of time while a motor is in a specific position, there is a short circuit over the windings -- is that amount findable in the specifications somewhere?
And how do you ensure that these sudden bursts are never too bad for the battery pack? eg, for the BMS that may be watching the pack's output current closely? Is it because their (BMS) response time is mostly averaged over a second's window, too, that it doesn't kill the peak demands?
And deeper -- where to see the capabilities of batteries to see how they respond to those very rapid pulses?
Thanks
