Abstract: A vent adaptor for placement inside a vent aperture that is itself placed within a battery housing. The vent adaptor has a cylindrical portion and a seal to create a gas-tight seal around the vent aperture. Along the upper portion of the vent adaptor are teeth which function to lock the vent adaptor in various configurations depending on the number and orientation of the various teeth and their interaction with various indentations in the vent aperture. The cylindrical portion may also have ribs with various geometries spaced at particular intervals to prevent the egress of the vent adaptor from the vent aperture. The vent adaptor may have internal diameter of at least 5 millimeters to accommodate an appropriately sized vent tube. A batten 7 with a housing that contains a vent aperture and a vent adaptor located inside the vent aperture.

Abstract: The present disclosure provides a battery pack for a hybrid vehicle. The battery pack includes: multiple battery cells, a housing, a first end plate, a second end plate, a bearing plate and an upper cover, wherein the housing is provided with a bottom portion and side walls extending from the periphery of the bottom portion and forming an upper portion opening; the housing is configured for accommodating the multiple battery cells and the two end plates, when the multiple battery cells are sequentially arranged and mounted into the housing, the first end plate and the second end plate are located at two end sides of the sequentially arranged multiple battery cells to laterally fix the multiple battery cells; the bearing plate is mounted above the top portions of the multiple battery cells; and the upper cover is mounted above the housing to cover the upper portion opening of the housing.

Abstract: An electrochemical cell includes a housing and a lid coupled to the housing. The electrochemical cell also includes a first member conductively coupled to the housing and configured to act as a first terminal for the electrochemical cell. The electrochemical cell further includes a second member electrically insulated from the lid and configured to act as a second terminal for the electrochemical cell. A first portion of the second member extends through the lid and a second portion of the second member extends in a direction generally perpendicular to the first portion.

Abstract: A device for aiding in the fracture of a vent of an electrochemical cell includes a main body having a first surface and a plurality of lobes extending out from the first surface of the main body such that an open space is provided between adjacent lobes. Each of the plurality of lobes are configured to make contact with the vent during deployment of the vent such that the vent completely separates from a bottom of the electrochemical cell. The open space provided between adjacent lobes is configured to allow gases from inside the electrochemical cell to pass through during deployment of the vent.

Abstract: A mandrel for an electrochemical cell includes an elongated hollow tube. At least one drive member is provided at an end of the hollow tube and is configured to receive a driver in order to rotate the mandrel. The drive member is configured to electrically insulate the hollow tube from an electrode that is wound around the hollow tube.
