CCs is more sophisticated than my old one, in which you had Mountain Mode, which was designed to provide electric assistance to the engine on steep inclines - but if you ran in that mode on the flat when it was below ?20 miles it would put some charge back into the EV battery. But of course you'd be working the ICE engine a bit harder so whether it was that economical I'm not sure.
Other than that it's really just KERS from, as CC says, mainly from slowing/braking. You can usually set the amount of "engine" braking - current car has 3 settings - and this determines how aggressively it brakes and thus charges the battery. On mine, the harshest setting is allegedly sufficiently fierce that the brake lights light up when you lift off (though I've not seen it happen on mine).
