A bodyshell structure for an electrically driveable motor vehicle includes a ventilation channel formed by a plurality of structural components that are connected to one another and delimit respective cavities. The ventilation channel has at least one inlet opening for inflow of a venting gas that emerges from a drive battery of the motor vehicle in an event of a thermal event and has at least one outlet opening via which the venting gas is dischargeable into a surrounding of the motor vehicle. A venting gas treatment device is disposed inside the ventilation channel where the venting gas and/or particles entrained with the venting gas is treatable by the venting gas treatment device.

Provided is a battery pack (10) the reliability of which can be enhanced. This battery pack (10) accommodates a secondary battery (14) inside a case (12). The battery pack includes: an exhaust port (22) that provides communication between an internal space of the case (12) for accommodating the secondary battery (14) and the outside and that discharges gas discharged from the secondary battery (14) from the inner space to the outside; and a heat exchange body (24) that is provided to the exhaust port (22) and is formed of a porous material having a three-dimensional mesh structure so that gas passes therethrough.

Disclosed is a battery cell, a battery module, a battery pack, and a vehicle. The battery cell may include a venting guide unit to discharge a venting gas in a desired direction and from a desired location of a cell case of the battery when a thermal event occurs. The battery cell may include an electrode assembly and an electrode lead connected to the electrode assembly. The cell case may be configured to accommodate the electrode assembly therein and support the electrode lead. The venting guide unit provided to the cell case may be configured to guide a venting gas to be discharged to a predetermined region of the cell case as an internal pressure of the cell case increases.

A battery pack (e.g., a battery pack for marine environments) can include a lower enclosure having an upper wall and defining a cavity, a plurality of battery cells positioned within the cavity, a radiator assembly positioned above the upper wall of the lower enclosure, a vent in the upper wall of the cavity, and/or a valve configured to selectively facilitate fluid communication between the cavity and the radiator assembly via the vent. In some embodiments, the valve is configured to open in response to increased pressure in the cavity resulting from a thermal runaway event. In some embodiments, the radiator is configured to create a tortuous path and collect flammable particulates from the thermal runaway event.

A battery module includes a first battery cell and a neighboring second battery cell, and an insulating member positioned therebetween. The battery module also includes a battery module enclosure surrounded by an external environment and configured to house each of the first battery cell, the second battery cell, and the insulating member. The battery module additionally includes a battery module cover mounted to the battery module enclosure. The battery module cover includes a vent feature configured to expel high temperature gases from the first battery cell and divert the high temperature gases away from the second battery cell directly to the external environment. The cover is thereby configured to minimize transfer of the high temperature gases from the first battery cell to the second battery cell and control propagation of a thermal runaway event in the battery module.

A battery-pack mounting structure for a vehicle, includes: a lower casing surrounding a lower side of a battery pack; an upper casing surrounding an upper side of the battery pack, and coupled to the lower casing to form a battery casing coupled to a bottom side of a vehicle body panel; a casing gasket provided in a coupling portion between the lower casing and the upper casing and implementing a sealing between the lower casing and the upper casing; an inlet gasket provided in a portion where an inlet provided in the upper casing is connected to the vehicle body panel and implementing a sealing between the inlet and the vehicle body panel; and an outlet gasket provided in a portion where an outlet provided in the upper casing is connected to the vehicle body panel and implementing a sealing between the outlet and the vehicle body panel.
