Almost: I would suggest just as your EV /may/ exceed the original GVWR.
Diseasels aside, I think Peter's statement above really does succinctly capture the essential point. In my experience, if your EV is within the original GVWR, then it is probable that you will not have to upgrade its brakes for typical driving conditions. If, as Peter suggests, your driving includes descending long steep hills, then you may want/need to upgrade the brakes even if you are under GVWR.
Obviously, if your driving includes descending grades that *require* the use of engine braking to prevent the friction brakes from failing in an ICE, then you will need to upgrade the brakes in an EV that is to be driven on the same grade. I personally would not count on regen as a substitute for adequately-sized mechanical brakes.
Cheers,
Roger.
