Vehicle with electric hybrid powering of external loads and engine-off capability

摘要

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 (22) is mechanically couplable with the power unit and electrically couplable with the at least one electrical storage device. The generator (22) 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 (22) 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.
