  • SYSTEM AND METHOD FOR MONITORING AC RIPPLE
    Publication number: 20140091783
    Abstract: A system capable of identifying various possible technical malfunctions with an uninterruptible power supply system by detecting AC ripple on a power bus of the UPS system. A battery monitor is positioned on the terminal posts of one or more batteries of the UPS system. The monitor, since it is connected with the power bus, is configured to measure and/or record AC ripple on the power bus. At the monitor or by way of communicating the AC ripple to a remote database and server, excessive ripple changes may generate an alert when such changes exceed a threshold or may be viewed through a graphical user interface.

  • Battery monitor
    Patent number: 7474228
    Abstract: An apparatus and method for monitoring at least one battery condition. An ac signal is applied to a battery. A difference between a signal output from the battery and a threshold determines a battery condition. The determined battery condition is transmitted remotely from the battery location either wirelessly or through a network to controller and/or is visibly displayed at the battery location.

  • Battery monitor with wireless remote communication
    Patent number: 7394394
    Abstract: An apparatus and method for monitoring at least one battery condition. A ac signal is applied to a battery. A difference between a signal output from the battery and a threshold determines a battery condition. The determined battery condition is transmitted remotely from the battery location through a controller to a network server and/or is visibly displayed at the battery location.

  • Battery monitor
    Patent number: 6885307
    Abstract: An apparatus and method for monitoring at least one battery. A reference ramp voltage signal is applied to a battery. A difference between a measurement ramp voltage signal output from the battery and the reference signal is compared with a threshold to determine battery condition. The determined battery condition can be transmitted remotely from the battery location.
