Regenerative Braking - how does it work?

I'm looking for a more detailed link on how Regenerative Breaking works.
I know they use generators at the wheels, but how do they engage/disengage them so that there isn't an extra energy load during driving?

Also, while i'm at it, some of the EV Cars I've seen on the news use more than one motor located at the wheels to reduce mechanical energy loss. How do they ensure that both motors turn at the same rate?
(EG: i've once had 2 exact same computers with cloned hard drives. one would boot up in 4 mins, the other would boot up in 2 mins even though they were "Exactly the same")
