A battery for a drive of a motor vehicle includes at least one energy reservoir, a housing, an interior, and a diffuser element. The housing surrounds the interior and the energy reservoir is arranged in the interior. The diffuser element is attached to an exterior of the housing. The diffuser element includes a plurality of diffuser outlets, a plurality of side faces, and a head face. The side faces are arranged between the housing and the head face. A housing outlet is arranged in the housing, which outlet is configured so as to discharge gas out of the interior in an outgoing direction to the diffuser element. The outgoing direction is directed from the housing outlet towards the head face. The diffuser outlets are arranged on the side faces.

A battery arrangement having a housing base arrangement and at least one battery unit which is arranged on the housing base arrangement and is arranged above the housing base arrangement with respect to a first direction and which comprises at least one battery cell. The at least one battery cell has a first side having a releasable degassing opening which is releasable for discharging a gas from the at least one battery cell. The housing base arrangement has at least one predetermined breaking point, which is designed, in dependence on a gas escape of a gas from the degassing opening of the at least one battery cell, to release an opening penetrating the housing base arrangement with respect to the first direction, in order to discharge the gas escaping from the degassing opening of the at least one battery cell through the released opening.

A battery arrangement having a cooling wall arrangement, which includes a cooling wall, and having a battery unit, arranged above the cooling wall arrangement in relation to a first direction, which includes a battery cell which has a first side having a releasable degassing opening facing toward the cooling wall. The battery arrangement has a degassing channel in which gas escaping from the degassing opening. The degassing channel is arranged below the releasable degassing opening and above the cooling wall with respect to the first direction and is designed in such a way that in case of the gas escape of the gas from the degassing opening, a first part of the gas escaping from the degassing opening chronologically first is introducible into the degassing channel.

A battery system includes: a battery pack including a battery housing and a plurality of battery cells accommodated within the battery housing; and a cover element covering an outer side of the battery housing. The battery housing has a housing exit at where a venting gas stream exhausted by one or more of the battery cells during a thermal runaway exits the battery housing, and the cover element covers the housing exit. The cover element forms a venting channel together with the outer side of the battery housing such that the venting gas stream exiting the housing exit is received and guided by the venting channel along the outer side of the battery housing to a channel exit of the venting channel.

In order to allow gas discharged from a pouch cell to be guided to a predetermined position, a power source device includes one or a plurality of pouch cells (10) having laminated film outer casing (11), and a housing member (20) enclosing the one or multiple pouch cells (10). The one or plurality of pouch cells (10) each includes thermally welded portion (13) formed by thermally welding the laminated film, and gas discharge portion (14) provided in at least a part of thermally welded portion (13). Housing member (20) includes exhaust port (22) communicating with gas discharge portion (14) of one or a plurality of pouch cells (10).

A battery module includes a battery cell stack in which a plurality of battery cells are stacked; a case configured to accommodate the battery cell stack and having a first discharge hole formed to discharge gas; an exhaust path member having a hole formed to communicate with the first discharge hole and mounted to the case to provide a discharge path of the gas so as to discharge the gas and prevent flame from leaking; and a cover coupled to the case to cover the exhaust path member and having a second discharge hole through which the gas moving through the exhaust path member is discharged.

Systems and methods are provided for a battery module. A battery module includes a module housing configured to hold a cell stack comprising a plurality of battery cells. A busbar assembly having an electrically conductive busbar is configured for electrical connection to electrode leads of the battery cells. The busbar assembly includes a gas outlet configured for discharging gas generated within the plurality of battery cells in a direction away from the cell stack, and the module housing includes a venting member configured to vent the gas discharged from the gas outlet to an outside of the module housing.

Provided are a battery tray and a power battery pack. The battery tray includes a tray body. The tray body includes a base plate, a side beam, and several partition plates, the side beam is disposed around the base plate and defines, together with the base plate, an accommodating space for battery cells. The partition plates are disposed on the base plate and divide the base plate into several regions for placing the battery cells. The partition plates and the side beam are each formed therein with an air passage and are in communication with each other. The partition plates are provided with several inlet vents, and the side beam is provided with at least one exhaust vent. The inlet vent is configured to introduce a flame, smoke or gas discharged from the battery cell into the air passage.
