First Claim
1. A vehicle, comprising:
- a power unit mechanically couplable with at least one primary load, said at least one primary load including a propulsion load;
at least one electrical storage device having an electrical output which is couplable with at least one external load over a drive period of time, each said external load being distinct from said at least one primary load;
a generator which is mechanically couplable with said power unit and electrically couplable with said at least one electrical storage device, said generator having an electrical charging output to said at least one electrical storage device; and
at least one electrical processing circuit configured for selectively coupling said at least one electrical storage device with at least one said external load, and for selectively coupling said generator with said at least one electrical storage device over a charging period of time, said charging output and said charging period of time being dependent upon said electrical output from said at least one electrical storage device and said drive period of time.

Abstract
A vehicle includes a power unit mechanically couplable with one or more primary loads, including a propulsion load. At least one electrical storage device has an electrical output which is couplable with at least one external load over a drive period of time. Each external load is distinct from the one or more primary loads. A generator is mechanically couplable with the power unit and electrically couplable with the at least one electrical storage device. The generator has an electrical charging output to the at least one electrical storage device. At least one electrical processing circuit is configured for selectively coupling the at least one electrical storage device with one or more external loads. The at least one electrical processing circuit is also configured for selectively coupling the generator with the at least one electrical storage device over a charging period of time. The charging output and the charging period of time are dependent upon the electrical output from the at least one electrical storage device and the drive period of time.
