Ah, so the answer is they do:
"Now, electric cars do actually use their motors as generators (no need for a separate part) sometimes… instead of friction brakes. So as you slow down, or control your speed going down a hill, instead of turning kinetic energy into heat as the brakes do, you instead generate some electricity and put it back in to the battery. This is called regenerative braking."
