Abstract

Embodiments of the present disclosure provide a method comprising providing a first adaptive threshold of charge for a battery within a hybrid vehicle and based upon the first adaptive threshold of charge for the battery, operating the hybrid vehicle in a mode of operation. The method also comprises automatically analyzing at least one condition and based upon the automatically analyzing at least one condition, automatically altering the first adaptive threshold of charge for the battery to provide a second adaptive threshold of charge for the battery that is different from the first adaptive threshold. Based upon automatically altering the first adaptive threshold of charge for the battery to provide a second adaptive threshold of charge for the battery, (i) a proportional use of power to be supplied by a fuel engine component and/or (ii) a proportional use of power to be supplied by an electric engine component is automatically altered.
