TLDR / BLUF: If frequent Supercharging (120KW) is hard on a battery, would 60KW of regenerative braking for any duration of time also be just as difficult?
I'm not an expert on AC Induction motors, but I'm making the assumption that the motor controller is taking multi-phase AC and turning it back into DC power during regen. From the battery's perspective, I'm guessing this looks like a 60KW flood of juice, similar to a 60KW DC fast charging session, albeit for a shorter time and quick taper to lower power levels. But if this process is repeated over and over again, would it make any measurable difference to put this wear in tear on comparatively inexpensive brake pads?
Until recent software updates, my April 2017 build S75D (350v) would supercharge at ~96KW max, so 60KW regen is not an insignificant rate compared to supercharging and occurs many times per drive.
What are your thoughts on this? Would this be insignificant or otherwise a non-issue?
