  • Patent number: 10847835
    Abstract: A battery management system monitors and controls the state of charge of a plurality of battery cells with a single data transceiver line. A sense board coupled to each cell monitors the battery cell voltage and temperature and reports the cell voltage in series, according to the location in series. A data request signal is sent by the control device of the battery management system through the single data transceiver line to initiate battery cell data transmission. The first battery cell in the series sends the first battery data upon receiving the data request signal and each subsequent battery cell in the series sends their respective battery data after a predetermined delay time set by two quaternary bits formed by a pair of voltage dividers. The state of charge may be displayed in real time on a graphical or numerical display.

  • Patent number: 10833513
    Abstract: Methods and systems for monitoring individual cell voltages of an energy storage system. The measured cell voltages can be reported back to a central controller. Based on parameters such as the overall health of the system, this controller can be adapted to decide which cells to balance, in which direction and optionally for how long. Balancing can be performed by cell monitoring and balancing units which can be implemented in hardware, i.e. as one or more circuits. The decision information from the controller can be reported to the cell monitoring and balancing units as a command.

  • Patent number: 10690725
    Abstract: A battery pack management system adjusts the relative state-of-charge of respective battery blocks in a battery pack to equalize (i.e., align, balance or otherwise make similar) the peak battery block voltages (i.e., maximum or “upper peak” battery block voltages when the battery pack is being charged and/or minimum or “lower peak” battery block voltages when the battery is being discharged). Upon detecting an anomalous battery block that exhibits outlier upper and lower peak voltages, the battery pack management system adjusts the relative state of charge of respective battery blocks to center their respective upper and lower peak voltages between operating limits, thus maximizing the operating margin of the battery pack as a whole.
