Bandwidth-Based Methodology for Controlling and Optimally Designing a Hybrid Power System

摘要

The present invention provides a novel system and method for a power management strategy for series hybrid power systems, such as for vehicles, with limited electrical energy storage capacity that distributes instantaneous power between a source of chemical energy and a small energy storage system (ESS) efficiently. The invention provides for minimizing the energy storage system while simultaneously allowing the chemical to electrical energy converter, e.g., an internal combustion motor/engine paired with an electrical generator and/or a fuel cell power source, to operate in pre-defined efficient regions of the power user's, or vehicle's, fuel efficiency map.
