If you are just using the battery as the buffer you shouldn't need a charge controller or anything other then a high voltage cut off that will only act as a safety.
A mechanical drive to the road is going to give you better economy then a generator if you are driving down the highway (long distance) and a generator is going to be easier to drive with for stop and go driving.
A power assisted battery trailer is something I've thought about building because you could use it for non EV's as well for hauling more then the vehicle could normally tow if you had a telescoping hitch that worked as the throttle, if tuned right you could even tow such a trailer with a bicycle.
