Global Optimization to Real Time Control of HEV Power Flow: Example of a Fuel Cell Hybrid Vehicle
نویسندگان
چکیده
Hybrid Electrical Vehicle (HEV) fuel economy highly depends on power allocation between the different power sources — engine and fuel cell — and the energy storage system(s). A generic global optimization algorithm has been developed to minimize fuel consumption by optimizing the powertrain power flows. This algorithm was applied on a Fuel Cell Hybrid Vehicle, and results were generated for several driving cycles. By using these results, a real-time control strategy was developed and implemented in PSAT (Powertrain System Analysis Toolkit). Methodology, as well as control strategy differences, will be discussed.
