  • Publication number: 20220190417
    Abstract: A battery housing for a battery module is disclosed. The battery housing has a plurality of exterior walls surrounding a base forming an internal section which is configured to receive one or more battery cells. The internal section has a bottom surface. A heat sink is joined to the bottom surface of the battery housing by a plastic deformation of a portion of the housing. A cover encloses the internal section of the battery housing. A battery module and a method of installation of a heat sink in a battery housing are also disclosed.

  • Publication number: 20220085443
    Abstract: Disclosed is an advanced battery module comprising a feature for the restraint of cell swelling. In particular, disclosed is an advanced battery module for a vehicle, comprising a housing having a first wall, second wall, third wall, and fourth wall wherein the first wall is perpendicular to the second wall and fourth wall, and the third wall is parallel to the first wall, wherein the first wall comprises a first wall member, a second wall member parallel to the first wall member, and a plurality of first wall cross-members extending between the first wall member and second wall member; wherein the plurality of first wall cross-members are angled relative to the first wall, at least the first wall and the third wall comprising a plastic; and a plurality of cells.

  • Patent number: 10271482
    Abstract: In combination: a) a cutting blade assembly having a frame and a first cutting blade member with a first cutting edge portion configured to cause relative movement between components on the cutting blade assembly whereby the at least first cutting edge portion effects severance of an object; and b) a protective sheath. The protective sheath can be moved relative to the cutting blade assembly between: a) a first separated position; and b) an assembled position. The protective sheath frictionally engages the cutting blade assembly to thereby be maintained in the assembled position. The protective sheath has at least one component that projects away from the cutting blade assembly and has oppositely facing surfaces that can be grasped between two fingers on a user's one hand to facilitate repositioning of the protective sheath.

  • Patent number: 10165728
    Abstract: An edger has a main frame that can be advanced controllably relative to subjacent terrain and a cutting assembly on the main frame. A drive rotates the cutting assembly around a first axis. The cutting assembly is configured to produce a trench in underlying terrain as the cutting assembly is rotated by the drive in operation. The cutting assembly has a perimeter edge with a contour extending over an axial distance. A shielding assembly defines a radially inwardly facing surface that resides radially outside of the perimeter edge of the cutting assembly. The radially inwardly facing surface has a shape that is at least nominally matched to the contour of an axial extent of the perimeter edge of the cutting assembly so that as the cutting assembly rotates the radially inwardly facing surface and perimeter edge of the cutting assembly cooperate to each avoid buildup of foreign matter on the other.
