Abstract: Aspects of the present disclosure involve a monitoring system for a plurality of batteries connected in series. In one example, the monitoring system includes a monitoring circuit to be coupled across each of a plurality of distinct contiguous subsets of the batteries as a unit. The monitoring circuit includes at least one test signal generation circuit to generate a test signal and apply the test signal to each subset of the batteries, and at least one response measurement circuit to measure a response of each subset of the batteries to the test signal. The monitoring system also includes a control circuit to identify at least one of the subsets of the batteries as including a failing battery based on the measured response of each subset of the batteries.

Abstract: Implementations of the present disclosure involve a system and method for load balancing a string of jars. The temperature and voltage of each jar is measured and a target voltage for the jar is set based on the measured temperature. A current is supplied to the jar in order to maintain, increase, or decrease the jar's voltage.

Abstract: The present disclosure provides a branch circuit monitoring (BCM) system that may include a first collector board with a first plurality of connector ports connected to a first plurality of branch circuits, and a second collector board with a second plurality of connector ports connected to a second plurality of branch circuits. Each of the first and second plurality of connector ports may receive a respective first and second plurality of connector plugs configured to be receivable in the respective first and second plurality connector ports. The first collector board may be coupled to an aggregator board such that the first plurality of current sensors may report branch circuit measurements to the aggregator board. The plugs may be connected to associated leads connected to respective first plurality and second plurality of current sensors. The first board and the second board may be in communication using a bus protocol.

Abstract: Implementations of the present disclosure involve a thermal monitoring system that includes multiple thermal sensor nodes and a control node. The thermal sensor nodes include an infrared sensor, an ambient temperature sensor, at least one LED, and a controller with a memory for storing temperature measurements and a sending and receiving information to and from the control node. The control node for receives, stores, and outputs temperature measurements from at least one thermal sensor node.

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.
