A traction battery pack assembly includes, among other things, first and second pieces of an enclosure having an interior area. An attachment rim is disposed at a periphery of the first piece. The attachment rim has a stand-off that includes a platform portion and turned flange. The platform portion extends outward from the interior area in a first direction. The platform portion provides an aperture. The turned flange extends away from the platform portion in a second direction and terminates at an end face. The second direction is transverse to the first direction. The aperture is configured to receive a fastener that clamps the end face against the second piece.

A fire protection coating and a fire barrier coated article are provided that comprise an inorganic binder and at least one inorganic filler, wherein the inorganic binder is selected from potassium silicate, sodium silicate, or a combination thereof, and wherein the at least one inorganic filler is selected from kaolin clay, talc, mica, mullite, phlogopite, muscovite montmorillonite, smectite, bentonite, illite, chlorite, sepiolite, attapulgite, halloysite, vermiculite, laponite, rectorite, perlite, and combinations thereof. The fire barrier article comprises flame resistant substrate layer having a first major surface and a second major surface, and a fire protection coating disposed on the first major surface of the flame resistant substrate layer.

In a battery pack, an exterior case accommodates therein a core pack including battery blocks coupled to one another. Each battery cell includes battery cells held at predetermined positions by a battery holder. Each battery block includes exhaust passage passing through the battery holder. The core pack has a valve-side end surface arranged at a first end thereof, and includes a partition wall between battery blocks coupled to one another. The partition wall has a through-hole opening at a position facing the exhaust passage. In the core pack, the exhaust passage formed in each battery block and the through-hole formed in partition wall are arranged on a straight line to constitute an exhaust duct for the exhaust gas. The exhaust gas discharged from the valve-side end surface arranged at the first end passes through the exhaust duct and then is discharged from an exhaust portion to an outside.

A battery enclosure and method for manufacturing the same from organosheet materials. The battery enclosure includes a top cover with crossbeams integrated therein by overmolding that secures to a bottom panel to enclose a space for containing components of a battery. The bottom panel includes overmolded structural ribs to provide strength and rigidity to the bottom panel. An outer cover removably secure the top cover to the bottom panel and includes a honeycomb structure to crush upon impact and protect the battery components. The method comprises forming each of the components of the battery enclosure from a mixture of organosheets, reinforcing members, and overmolded elements to reduce the weight and complexity of manufacturing for the battery enclosure.

An encapsulation structure for preventing thermal damage to a battery includes a cooling module air guide formed on a front outer peripheral surface of a cooling module so as to protrude in a forward direction of a vehicle; an outside air line communicating with the cooling module air guide such that outside air flowing into the cooling module air guide is introduced through the outside air line; and a battery case formed to enclose the battery. The battery case communicates with the outside air line.

A battery module, which includes at least one battery cell and a module case for packaging the at least one battery cell, wherein the module case includes: a top cover configured to cover an upper side of the at least one battery cell; and a side plate configured to cover all of opposing side surfaces of the top cover and opposing side surfaces of the at least one battery cell and configured to be coupled to the top cover by fitting.

A battery module, which includes at least one battery cell and a module case for packaging the at least one battery cell, wherein the module case includes: a top cover configured to cover an upper side of the at least one battery cell; and a side plate configured to cover all of opposing side surfaces of the top cover and opposing side surfaces of the at least one battery cell and configured to be coupled to the top cover by fitting.

The invention relates to a housing for a cell stack of a battery, comprising: an integral frame from accommodating the cell stack, wherein the frame surrounds at least three end faces of a cell stack which is accommodated in the housing, and at least one electrically conductive connecting element for establishing an electrical connection between an external connection and a cell stack which is accommodated in the housing is integrated in the frame; and a cover for covering sides, in particular all sides, of a cell stack which is received in the housing, which sides are not surrounded by the frame.

A battery pack includes a plurality of batteries each including a discharge valve that opens when an internal pressure becomes higher than a set pressure, and case housing batteries. Case has an integrated structure of plastic resin case and metal plate, resin case has heat radiation opening closed by metal plate, and metal plate has a plurality of smoke discharge holes in closed region where heat radiation opening of resin case is closed.
