  • Publication number: 20240191424
    Abstract: A cyclone filter includes a body including a cylindrical surface extending between a first end and a second end, and defining a cavity of the cyclone filter. An air inlet is formed through the cylindrical surface and is configured to receive airflow from a laundry cabinet and to direct the airflow along the cylindrical surface within the cavity. A vortex diverter extends within the cavity from the second end and is configured to interrupt airflow as it passes within the cavity between the diverter and the cylindrical surface to separate particulates from the airflow. A particulate outlet formed through the cylindrical surface and axially spaced from the air inlet is configured to direct particulates separated from the airflow toward a particulate receptacle.

  • Patent number: 11614491
    Abstract: System, methods, and other embodiments described herein relate to improving the cycling of batteries by using data and a hierarchical Bayesian model (HBM) for predicting the cycle life of a cycling protocol. In one embodiment, a method includes classifying cycle life of a battery into a class using battery data from cycling with a protocol, wherein the class represents cycle life distributions of cycling protocols. The method also includes quantifying, using the class in a HBM, variability for the battery induced by the protocol. The method also includes predicting, using the HBM, an adjusted cycle life for the protocol according to the variability. The method also includes communicating the adjusted cycle life to operate the battery.

  • Patent number: 11226374
    Abstract: A method of using data-driven predictive modeling to predict and classify battery cells by lifetime is provided that includes collecting a training dataset by cycling battery cells between a voltage V1 and a voltage V2, continuously measuring battery cell voltage, current, can temperature, and internal resistance during cycling, generating a discharge voltage curve for each cell that is dependent on a discharge capacity for a given cycle, calculating, using data from the discharge voltage curve, a cycle-to-cycle evolution of cell charge to output a cell voltage versus charge curve Q(V), generating transformations of ?Q(V), generating transformations of data streams that include capacity, temperature and internal resistance, applying a machine learning model to determine a combination of a subset of the transformations to predict cell operation characteristics, and applying the machine learning model to output the predicted battery operation characteristics.

  • Patent number: 9601732
    Abstract: A battery module is provided. The battery module includes a plurality of battery cell assemblies configured to electrically communicate with each other. Each battery cell assembly has an electrode stack enclosed by a case. The electrode stack is positioned in the case to form one or more peripheral spaces between the electrode stack and the case. Support members are positioned adjacent to each of the battery cell assemblies to contact a desired portion of the electrode stack. The support members are configured to focus a compressive force on a desired portion of the electrode stack. The compressive force urges gases formed during operation of the electrode stack into the peripheral spaces within the case.

  • Patent number: 9130231
    Abstract: In a lithium ion battery, one or more chelating agents may be attached to a microporous polymer separator for placement between a negative electrode and a positive electrode or to a polymer binder material used to construct the negative electrode, the positive electrode, or both. The chelating agents may comprise, for example, at least one of a crown ether, a crown ether, a podand, a lariat ether, a calixarene, a calixcrown, or mixtures thereof. The chelating agents can help improve the useful life of the lithium ion battery by complexing with unwanted metal cations that may become present in the battery's electrolyte solution while, at the same time, not significantly interfering with the movement of lithium ions between the negative and positive electrodes.
