Self Charging Chevy Volt

This was an expirement to see how quickly the on board generator on the Chevy Volt will recharge the battery. Say what you say, the volt doesn't recharge it's own battery. Well it can, to 40% to be exact, and in the name of science, I am going to prove it. There is no reason to ever do this, as it would cost much more to charge the battery this way, but if the computer would allow it, the on board generator could bring the car to a full charge in 40 minutes. A 10 minute run used 1 liter of gas, as provided 10 miles (16KM) of electric range. There for a 40 minute run should provide a full charge, but as expected, the engine only charged the battery to the 14-15 mile range, as it shut down at exactly 15 minutes. Now all they need is a DC "output" port so volt drivers could provie a mobile charge solution to those less fortunate drivers that run their Leafs flat on the freeway!
