William B. Studyvin has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method and system for cell equalization with charging sources and shunt regulators
    Patent number: 7825629
    Abstract: A system and method for charging a rechargeable, or secondary, battery including a series string of cells, includes a topology of charging sources that selectively provides charging current to cells that need to be charged, but avoids overcharging cells that are already charged above a predetermined voltage threshold. Based on individual cell voltage measurements, the charging current is controlled in a manner to direct charging current to the battery cell(s) needing charge until these cells are fully charged, and by-passes battery cells that are fully charged or become fully charged.
    Type: Grant
    Filed: July 2, 2009
    Date of Patent: November 2, 2010
    Assignee: EaglePicher Technologies
    Inventors: William B. Studyvin, Eric Coatney, Tim Pennock, Phillip Shimp, Greg Miller
