Abstract: A battery module construction that provides passive resistance to propagation of cell failure, such as thermal runaway. The walls of cells of a battery module may be thermally isolated from each other by securing cells in a frame formed of thermal insulating material, separating the cells from one another, thereby limiting thermal energy from propagating directly between adjacent cells. A vent layer may permit ejection of hot gases and other ejecta into an air gap above the cells, venting the ejecta and dissipating thermal energy. The vent layer may be formed from, e.g., a frangible layer of dielectric gel, or a plastic vent tray with apertures for venting of ejecta and passage of wiring with collectors mounted over the vent tray. A heat sink or cooling module may be thermally coupled to an opposite end of cells to further aid thermal energy removal from the module.

Abstract: A battery module is formed from a plurality of battery cells having top and bottom electrodes. Top and bottom collector plates overlay, and are electrically connected with, the battery cell top and bottom electrodes. The collector plates may be formed wholly or primarily from copper. Cell apertures may be formed within the collector plates overlying each cell, with collector arms extending into said apertures for connection with an underlying cell electrode. The collector arms may include a fusible link for each cell. A bridge collector plate may span subsets of cells, and include a module-level fusible link formed therein. A current concentrator, such as a dimple or depression, may be formed in a collector arm to facilitate resistance welding of the copper collector plates to underlying battery cells, which may include electrodes formed from steel or other material more resistive than the copper collector plates.

Abstract: A suction cover gland tool includes a handle having a first end and a second end, opposite the first end, the handle having a through bore extending from the first end of the handle to the second end of the handle. The tool also includes a first cap disposed on the first end of the handle. The tool also includes a second cap disposed on the second end of the handle. The tool also includes a slide bar at least partially disposed within the through bore of the handle and adapted to slidingly mate with the second cap. The tool also includes an engaging member disposed on an end of the slide bar, the engaging member being adapted to mate with a receiving portion of a suction cover gland.

Abstract: An assembly for monitoring the operation of a large format battery module. Printed circuit boards may be routed within a battery module to electrically interconnect collector structures with a battery module monitoring circuit. Flexible printed circuits (FPCs) may be wrapped around one or more sides of a battery module and secured to it, such as via adhesive. Voltage monitoring FPCs may be applied to one or more side surfaces to electrically interconnect battery module collector structures with a monitoring circuit. Temperature monitoring FPCs may interconnect temperature sensors with the monitoring circuit. In some embodiments, one or more serpentine PCBs may be installed in a central channel between cells beneath a plurality of collector structures. The collector structures may include extensions overlaying the serpentine PCBs for direct welding to a steel pad on one of the serpentine PCBs.

Abstract: A mounting assembly mounts a fluid end unit to a power end unit and includes first and second end members, and a coupling. A first end of the first end member is a threaded shaft configured to be received in a mounting aperture of a power end unit. A first end of the second end member is a threaded shaft configured to be received in a mounting aperture of a fluid end unit corresponding to the mounting aperture of the power end unit. The coupling couples and extends the first end member and the second end member and may be removed therefrom without changing a relative position of the second end member to the first end member.
