    Abstract: The sealed battery has a battery container (4, 5) and a power generating element sealed inside the battery container. The battery container is provided with a fill opening (12), an annular ridge (16), which extends around the entire circumference of the outer face surrounding the fill opening, and an annular indentation (15) on the inside of the inner wall surface of the annular ridge, and has a sealing cap (8), which fits into the annular indentation and covers the fill opening. The sealing cap is joined by being welded to the inner wall surface of the annular ridge around the entire circumference at the edge thereof. Since heat is not well transferred from the inside to the outside of the outer wall surface of the annular ridge, the effective thermal capacity during welding is mostly determined by the structure of the area inside the outer wall surface of the annular ridge. Consequently, the effective thermal capacity is nearly uniform independent of direction.

  • Publication number: 20140154538
    Abstract: A battery pack includes a space as a heat carrier flow path that is formed between the adjacent battery modules; and protrusions that protrude toward an inside of the space, and that are arranged on surfaces of opposing surfaces and that define the space. The protrusions have a longitudinal direction when viewed from a protruding direction. The plurality of protrusions arranged on one surface of the opposing surfaces and the plurality of protrusions arranged on the other surface of the opposing surfaces are arranged in positions that are offset, in a flow direction of the heat carrier, from positions that oppose each other across the space. The longitudinal direction of the protrusions arranged on the one surface and the longitudinal direction of the protrusions arranged on the other surface are inclined in the same direction, with respect to the flow direction.

  • Patent number: 8741467
    Abstract: Cooling air intake port (52), cooling air exhaust port (55), and securing walls (86, 87), which contact and secure the side surfaces of one or more battery cells (72), may be defined within two battery pack housing halves (50, 80). When battery pack (99) is assembled, at least one cooling air passage (91, 92) is defined by the side surfaces of the battery cells, the interior surface of the battery pack housing, and the securing walls. The cooling air passage connects the cooling air intake port to the cooling air exhaust port. By forcing cooling air through the cooling air passage, the battery cells can be effectively and efficiently cooled.

  • Patent number: 8733465
    Abstract: A device for suppressing fires generated by lithium-ion batteries exhibiting thermal runaway. The device can include a thermally insulating enclosure for housing one or more battery cells. A fluid delivery system having a heat/temperature sensitive tube passes through each enclosure and contains an agent capable of extinguishing fires. When the cell or battery starts to undergo thermal runaway, the increase in temperature or the eruption of open flame causes the fluid delivery system to rupture inside the enclosure. The agent leaks out of the rupture and is transported into the enclosure and onto the malfunctioning cell or battery. Any fire is suppressed and the cell or battery is cooled down by the agent.
