You get no where near that much energy back. 5% on average.
5% is roughly the amount of range extension that regen provides. It can
be more if you make very frequent stops (like a delivery vehicle), or
live in a very hilly area. Otherwise, you don't use the brakes enough to
get more than a few percent of the energy you're using to drive.
But the peak regen current can easily be 100s of amps (during the brief
time that you are braking). Most controllers that can do regen can
deliver about the same amount of regen current as they can motoring current.
Note that when you *do* get 100's of amps of regen current, you are
decelerating very fast! I had an EV with a 500 amp aircraft
starter/generator as its motor; it would easily deliver over 500 amps of
regen. But when it did, you'd better be on dry pavement or it would skid
the tires!
