Abstract
Provided herein are energy source systems for a vehicle. One energy source system for a vehicle includes a battery having a plurality of cells coupled in series with one another and adapted to be coupled to an alternator of the vehicle. The energy source system for the vehicle also includes one or more ultracapacitors coupled in series with one another and adapted to be coupled to starting components of the vehicle. The battery and the one or more ultracapacitors are coupled to one another in a parallel arrangement, and a combined voltage of the battery cells is substantially matched with a combined voltage of the one or more ultracapacitors.
