  • Patent number: 12388285
    Abstract: A method for managing a plurality of batteries that are electrically coupled together includes (1) monitoring respective voltages of the plurality of batteries and (2) in response to a respective voltage of a first battery of the plurality of batteries reaching a first threshold value at a first time, reducing a charge or discharge rate of the first battery, relative to at least a second battery of the plurality of batteries. Charge and discharge rates may be adaptively managed such that each battery reaches the first threshold value at substantially the same time.

  • Publication number: 20250233431
    Abstract: A battery stack includes a plurality of battery management system (BMS) nodes and a controller. Each BMS node includes a battery, an isolation switch configured to selectably isolate the battery of the BMS node from the batteries of the other BMS nodes, and a bypass switch configured to selectably provide a path for electrical current flowing through the battery stack to bypass the battery of the BMS node. The batteries of the BMS nodes are electrically coupled in series. The controller is configured to control the isolation switch and the bypass switch of each BMS node such that the battery of each BMS node can be individually connected to and disconnected from an electrical power source/sink.

  • Patent number: 12352715
    Abstract: Described methods and systems are used for in-situ impedance spectroscopy analysis of battery cells in multi-cell battery packs. Specifically, the cell impedances are determined while the pack continues to operate, such as being charged or discharged. For example, the pack voltage/power output remains unchanged while this analysis is initiated, performed, and ended. Cell impedance is determined based on the cell's response to the signal applied to the cell. For example, a current through the cell is charged while monitoring cells' voltage response. Although the power output of the changes during this testing, but the operation of the pack is not impacted due to the power compensation provided by one or more other cells in the pack thereby ensuring uninterrupted operation of the pack. This in situ testing is provided by the unique architecture of the pack, comprising multiple nodes and individual node controllers.

    Abstract: A method for augmenting one or more batteries in an energy storage system includes exchanging energy between one or more first batteries of the energy storage system and a source/load via a plurality of battery power buses. Each of the one or more first batteries is electrically coupled to the plurality of battery power buses without use of a power converter electrically coupled between the first battery and the plurality of battery power buses. The method further includes (a) augmenting the one or more first batteries via one or more augmentation batteries of an augmentation node, where the one or more augmentation batteries are electrically coupled to the plurality of battery power buses via at least one augmentation power converter, and (b) controlling operation of the at least one augmentation power converter at least partially based on state of health of the one or more first batteries.

  • Patent number: 12218328
    Abstract: A method for thermal management performed by a controller of an energy storage system, where the energy storage system includes at least a first battery module, a second battery module, a first battery management system (BMS) node, and a second BMS node. The first BMS node is configured to control operation of the first battery module, and the second BMS node is configured to control operation of the second battery module. The method includes (a) determining a first temperature profile difference representing a difference between an actual temperature profile of the first battery module and a desired temperature profile of the first battery module, (b) determining a first operation adjustment representing a desired change in operation of the first battery module for decreasing the first temperature profile difference, and (c) controlling the first BMS node to change operation of the first battery module according to the first operation adjustment.

  • Patent number: 12158507
    Abstract: Described methods and systems provide in-situ leakage current testing of battery cells in battery packs even while these packs operate. Specifically, an external electrical current is discontinued through a tested battery cell using a node controller, to which the tested battery cell is independently connected. Changes in the open circuit voltage (OCV) are then detected by the node controller for a set period time. Any voltage change, associated with taking the tested cell offline, is compensated by one or more other cells in the battery pack. The overall pack current and voltage remains substantially unchanged (based on the application demands), while the in-situ leakage current testing is initiated, performed, and/or completed. The OCV changes are then used to determine the leakage current of the tested cell and, in some examples, to determine the state of health of this cell and/or adjust the operating parameters of this cell.

  • Patent number: 12155241
    Abstract: A method for managing a plurality of stacks of electrochemical cells, where the plurality of stacks are electrically coupled in parallel in a battery. The method includes (a) operating the plurality of stacks to execute a global operating strategy, (b) controlling one or more first power converters to change operation of one or more first stacks of the plurality of stacks to execute a first local operating strategy of operating the one or more first stacks at one of a constant power and a constant current, and (c) controlling one or more second power converters to change operation of one or more second stacks of the plurality of stacks to compensate for change in operation of the one or more first stacks caused by executing the first local operating strategy, and thereby maintain the global operating strategy of the battery while executing the first local operating strategy.
