  • Publication number: 20250023948
    Abstract: A battery management unit, BMU, configured to communicate, in parallel, with a plurality of cell monitoring circuits, CMCs, configured to provide for monitoring of battery cells and store a chain-identifier parameter initially comprising a predetermined default value, wherein the BMU is configured to perform a chain-identifier parameter assignment procedure comprising assigning a different chain-identifier parameter to each of the plurality of CMCs, wherein said assigning comprises using a unique ID of each CMC to individually select each one of the plurality of CMCs when assigning the respective different chain-identifier parameter, wherein the unique ID of each CMC is received by the BMU in response to the BMU being configured to send, in parallel to the CMCs using the predetermined default value, one or more request messages requesting that they report their unique IDs to the BMU.

  • Publication number: 20230123869
    Abstract: A battery management system for tracking a state of charge of a battery including multiple cells including a coulomb counter (CC) estimator and an artificial intelligence (AI) estimator. The CC estimator determines a charge difference over time for tracking changes of a state of charge of each cell and updates a corresponding state of charge value. The AI estimator converts a set of sample values of a cell into an estimated state of charge for calibrating the cell. A controller may periodically invoke the AI estimator to calibrate the state of charge of each cell and to update a corresponding state of charge value. Processing by the AI estimator may be minimized by being used only to calibrate each cell before combined error of the CC estimator reaches a predetermined threshold. AI based calibration may use Long Short-Term Memories and may further incorporate voltage mean and voltage variance over time.

  • Patent number: 9812941
    Abstract: A transistor circuit includes a transistor having a control electrode, a first current electrode, and a second current electrode. A turn off mode change circuit has a signal input that receives a series of pulses, an output coupled to the control electrode of the transistor, and a control input. The turn off mode change circuit has a fast turn off mode and a slow turn off mode. A turn off mode detection circuit is coupled between the first current electrode and the second current electrode. The turn off mode change circuit detects when a transition from the fast turn off mode to the slow turn off mode is desired and when a transition from the slow turn off mode to the fast transition mode may be performed.
