Abstract
A portable generator system having a generator for generating an electrical output signal, an internal combustion engine for driving the generator, a starter for starting the internal combustion engine, an alternator for generating an AC signal for powering a charger assembly, a battery pack, and a charger subsystem. The charger system has a charger assembly that receives the AC signal and generates a DC charging signal for recharging the battery pack. The charger assembly has a first switch and a second switch. The first switch is used to apply an output of the battery to energize the starter. The second switch, when placed in a Start position, enables current from the battery pack to energize the starter while inhibiting the application of the DC charging signal to the battery pack. When placed in the Charge position, the second switch inhibits the battery pack output from energizing the starter while enabling the DC charging signal to be applied to the battery pack.
