  • Method and system for cell equalization with isolated charging sources
    Patent number: 7928691
    Abstract: A system and method for charging a rechargeable, or secondary, battery including a series string of battery cells, a topology of charging sources that selectively provides charging current to battery cells that need to be charged, but avoids overcharging battery 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 bypasses battery cells that are fully charged or become fully charged.
    Type: Grant
    Filed: October 26, 2005
    Date of Patent: April 19, 2011
    Assignee: EaglePicher Technologies
    Inventors: William B Studyvin, Eric Coatney, Tim Pennock, Phillip Shimp, Greg Miller
  • 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.
