A “genset” is a trailer that contains a generator and combustion engine for use as a range-extending module for electric vehicles. The idea is not new, but is not very popularized either. Considering some of the limitations of pure EVs, though, and the downsides to hybrids, a genset could be the answer.

Here’s the idea: for everyday use, the car is used alone, running entirely on battery power.  For longer-range needs, like trips to grandma’s or overnighters and vacations, the genset trailer would be attached to the car and used to keep the batteries charged on the road.

Currently, AC Propulsion (you know, the guys who make the eBox with Tom Hanks) make a genset called the Long Ranger. It’s a gasoline-fueled genset trailer that uses a 500cc Kawasaki engine with a 9.5 gallon fuel tank and gets around 35mpg when continuously running. It’s generator outputs 20kW DC and the trailer is built to maintain speeds up to 80mph.

This idea is a great concept that could divorce us from the hybrid-electric car idea (which is dubious, when you consider its questionable efficiency) and move us over into pure electrics. The trailers, rather than being purchased, could be rented from dealerships or car rental agencies. Who knows? Housing complexes and neighborhoods could make these trailers available as added incentives for their residents. Just as they do golf carts and other toys.

Gensets are an idea that isn’t tossed around much, but makes perfect sense once you see it.
