  • Patent number: 11145943
    Abstract: A battery pack includes a battery unit including rectangular secondary batteries, each including a sealing plate and positive and negative electrode terminals attached to the sealing plate; a bus bar that connects the rectangular secondary batteries together in parallel; an insulating plate disposed between the sealing plates of the rectangular secondary batteries and the bus bar; and a short-circuit breaking portion that interrupts an electric conduction path between the rectangular secondary batteries connected in parallel by allowing each sealing plate to bulge outward in response to an internal pressure rise of the battery to push up the insulating plate and the bus bar. A portion of each sealing plate that bulges most protrudes outward by greater than or equal to 1.5 mm from an outer peripheral edge of the sealing plate when a pressure in the corresponding rectangular secondary battery reaches the operating pressure of a gas release valve.

  • Patent number: 10337368
    Abstract: To provide an engine device with high reliability and high safety in which a pipe conduit in a portion where a blow-by gas having leaked from a combustion chamber is merged with intake air (outdoor air) is not blocked with ice coating even in use in a cold region, especially an arctic region at ?20° C. or less, a blow-by gas mixed joint configured to introduce a blow-by gas flowing in a returning hose to an intake pipe includes a blow-by gas guide plate that defines introduction space expanding upstream and downstream of a blow-by gas inlet in an intake direction of an intake passage. The blow-by gas guide plate closes an upstream end of a part of the introduction space expanding upstream of a blow-by gas inlet and opens a downstream end of a part of the introduction space expanding downward of the blow-by gas inlet in the intake passage.
