  • Adjustable battery charger for UPS
    Patent number: 7944182
    Abstract: An uninterruptible power supply (UPS) having an adjustable battery charger that generates a charger current, and a controller, coupled to the adjustable battery charger, that receives a signal representative of a system constraint and provides a reference, based on the signal, to the adjustable battery charger to control an amplitude of the charger current supplied by the adjustable battery charger based on the system constraint. The system constraint may include, for example, a maximum input current to the UPS, maximum charging current of the battery cell, and maximum and/or minimum charger current values.
    Type: Grant
    Filed: August 3, 2007
    Date of Patent: May 17, 2011
    Assignee: American Power Conversion Corporation

  • Method and apparatus for monitoring energy storage devices
    Publication number: 20050162129
    Abstract: An improved battery, monitoring circuit and method for communicating with the battery is provided. Such batteries and communication methods are particularly useful in UPS systems that use such batteries to provide back-up power to electrical loads. In one aspect, performance, manufacturing, trend and/or other data are stored in non-volatile memory of the battery and are communicated to an external system such as a UPS. In another aspect, a method for communicating via single-wire interface is provided. In one aspect, a same interface is used to communicate with both conventional batteries and improved batteries having increased monitoring capabilities.
