Three-phase (TC.CC.CV ) charging system
« on: July 17, 2013, 05:50:22 AM »
  This system usually design with battery repair function.

    When the voltage of battery drops to 3.0V or below, it will output a 100mA±10% current to process repairing charging; (TC phase)

    When the battery voltage rises to 3.0V, it starts a 500mA±10% CC charging phase; (CC phase)

    When it rises to 4.1V, it outputs a 4.2V±1% CV for charging; When voltage reaches 4.2V±1%, charging stops and cuts the current off. (CV phase)

    Then system will monitor the battery continuously, the charging procedure restarts when it detects the voltage drop to 4.0V below which function maintains a constant and fully charged battery.

   When input voltage or AC adapter/car adapter is removed, system will enter a low current status and deduct the leakage current less than 4uA automatically.

   The “three-phase system”  which is a reliable intelligent charging method.
