Starter/Alternator Design for Optimized Hybrid Fuel Economy
A Starter/Alternator (S/A) has been developed at Ford Research laboratories for hybrid electric vehicle applications. During development, the vehicle concept of operation and the system performance requirements were used to select the proper technology. The specification development, component selection and subsystem operation process is described. Subsystem performance and vehicle fuel economy are compared and evaluated using hybrid vehicle simulation analysis. These results can be used to identify potential subsystem modifications and alternative vehicle control strategies.
