Embodiment Construction
[0018]Embodiments of the invention are directed to a supercapacitor array and charger-implemented method of charging thereof in a controlled manner to maximize energy extraction and array lifetime. A charger included as part of a system for starting an internal combustion engine of a motor vehicle is programmed to temporarily bump-up a voltage of the supercapacitor array in an on-demand fashion, so as to maximize a voltage available from the supercapacitor array when starting the engine without significantly impacting the operational lifetime of the supercapacitor array.
[0019]Embodiments of the invention are described below as being directed to a system for starting an internal combustion engine in construction, agriculture, heavy trucking, and other specialty vehicles—with such vehicles including, for example, asphalt pavers, large tractors, road graders, field harvesters, and so forth. However, it is recognized that the charger and method performed thereby for charging the superca...
