This really isn't that complicated. Electric cars use a combination of regenerative braking (using the generator to convert kinetic energy; forward velocity, into electric energy) and using the disc brakes when regenerative braking doesn't slow you down fast enough. This results in much less wear on the brake pads and callipers.
