  • Publication number: 20240072385
    Abstract: A power supply includes a core housing having a first housing portion and a second housing portion together forming a cavity. The first housing portion is separable from the second housing portion to access the cavity. A battery core includes a plurality of battery cells received within the cavity. The plurality of battery cells are divided into a first group of interconnected battery cells and a second group of battery interconnected cells. The battery core also includes a conductor mechanically and electrically connecting a first terminal of the first group of interconnected battery cells and a second terminal of the second group of interconnected battery cells thereby connecting the first group of interconnected battery cells in series with the second group of interconnected battery cells. The conductor is disconnected from the first terminal or the second terminal when the first housing portion is separated from the second housing portion.

  • Publication number: 20220198101
    Abstract: A computer may display on a graphical user interface (GUI) a component library including a set of components relating to a compressed air system. The GUI may have a modeling interface for configuring a virtual model using the set of components. The computer may simulate the virtual model to determine one or more optimizations to the compressed air system. The computer may also determine the cost of implementing the compressor system optimization.

  • Publication number: 20210281084
    Abstract: A portable power supply including a first subcore including a first plurality of battery cells, a second subcore including a second plurality battery cells and electrically connected in series with the first subcore, and a controller including an electronic processor. The controller is configured to receive a first voltage value indicative of a voltage of the first plurality of battery cells from the first subcore and a second voltage value indicative of a voltage of the second plurality of battery cells from the second subcore. The controller is further configured to determine a difference between the first voltage value and the second voltage value, compare the difference to a balance threshold, and perform a balancing operation when the difference is greater than or equal to the balance threshold.
