Patent ID: 7779616

Claim:
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.
