  • Switched Reluctance Generator Integrated Controls
    Publication number: 20120161723
    Abstract: A method of controlling a generator (110) of an electric drive (104) associated with an engine (102) is provided. The method may determine an operational state of the electric drive (104) based on a speed of the engine (102), and selectively engage one of a map-lookup control scheme (150) and a fixed-theta off control scheme (152) for operating the generator (110) based on the operational state of the electric drive (104).

  • IN-SITU PORE GENERATION IN LEAD-ACID BATTERY SEPARATOR
    Publication number: 20110045339
    Abstract: A microporous polyethylene battery separator material (212), for use in a flooded-cell type lead-acid battery, benefits from increased porosity, enhanced wettability, and exceptionally low electrical resistance when an electrolyte-soluble pore former is employed in the manufacturing process. The pore former (210) is soluble in electrolytic fluid and therefore dissolves in-situ in sulfuric acid during battery assembly. The dissolution of the pore former leaves behind additional, larger voids (220) in the separator material and thereby enhances ionic diffusion and improves battery performance.
