ABSTRACT:
A hybrid prolusion system comprising a first energy storage unit operable to supply power to a traction drive motor. A second energy storage unit is coupled with the first energy storage unit to provide additional power on demand to the traction drive motor. An auxiliary power unit (APU) is used to charge the first battery to maintain a desired voltage across the first energy storage unit.
