摘要： A mid-string voltage sensor is disposed in proximity to a storage-battery string and determines an error signal between the expected mid-string voltage and the actual mid-string voltage to aid in detecting faults in one or more of the batteries of the string. Each sensor is connected to or close to the battery string terminals and to a terminal at the midpoint of the group of batteries connected in series. The arrangement suppresses errors due to common-impedance coupling, and the measured voltages are decoupled from the battery system, prior to determining the error. A fractional error voltage is derived using a logarithmic ratio amplifier so that the error signal determination is performed at the sensor, with the resultant error signal suitable for coupling to a battery health monitor.

摘要： Where an Uninterruptable Power Supply (UPS) is used in a system to ensure highly reliable power supply to an electronic system, occasional maintenance or repair of the UPS or its storage batteries may be required. Effecting this servicing while ensuring that the utility power continues to be supplied to the load may involve a Maintenance Bypass Assembly (MBA) comprising a plurality of manually-operated circuit breakers. The possibility of an incorrect actuation of such circuit breakers is precluded by the coordination of a plurality of electromechanically actuated circuit breakers in communication with a controller that may store a table of permitted state transitions and sequences for safe operation. Such operation may be confirmed by one or more sensors monitored by the controller.

摘要： Storage batteries connected in series in an uninterruptable or back-up power supply system may have voltage potential differences between exposed terminals or conductors that exceed safety limits. A demountable insulating shield having apertures may be positioned so that the series string may be broken into a plurality of series sub-strings having a lesser potential difference has a cover over the aperture through which the series string configuration may be connected and disconnected. The cover may be an insulating material removably fastened to the insulating shield or a sliding cover that is captivated to the insulating shield. When the series string has been divided in to the sub-strings, the insulating shield may be demounted from the structure housing the batteries so that the batteries or their connections may be serviced.

摘要： A system and method for monitoring the status of a system of battery strings is described. The battery string current is measured by a current sensor urged into contact with a metallic element in which the battery string current is flowing. The time history of the battery string current and voltage is interpreted to determine whether the battery string is discharging, charging or in a fully charged state. A moving average current in the charging state is used to establish a threshold for determining whether a thermal runaway condition exists. The moving average is maintained at the value that existed at a time when the battery string has been disconnected from the system current bus.

摘要： A system and method for monitoring the status of a system of battery strings is described. The system includes a current sensor for each of the battery strings, and a controller configured to compare the measured current with criteria to determine whether the battery is in a thermal runaway state. Prior to entering the thermal runaway state the battery current characteristics may indicate other less serious states. Warning messages are provided for selected events, and the battery string is disconnected from the remainder of the system when a thermal runaway state is encountered. The system may provide a local indication of status and may also interface with a communications network to provide for remote monitoring.
