An assembly for a vehicle comprising at least two battery blocks, each having a casing in which the battery block is enclosed and that has a connection face. The outer skin of the vehicle has an outlet orifice. There is a main duct connected to the outlet orifice. For each casing, an evacuation duct is connected between the connection face and the main duct. A damping unit is provided at the joint between each connection face and the evacuation duct. A damping unit is provided at the joint between the main duct and the outlet orifice. Each damping unit limits the amplitude of an overpressure propagating from the casing towards the outlet orifice. Such an assembly enables an overpressure to be damped in the event of a battery being damaged, inter alia.

A battery vent assembly that includes an expanded metal filter collar which acts as a heat sink to cool and overheating battery. Further the vent assembly acts as a particulate filter and flame arrestor which prevents and/or reduces flames and particulate slag projectiles from being expelled outside an individual cell or bank of cells in a battery. The Directional Flow Expanded Metal (DFEM) and Variable Expanded Metal (VEM) utilizes directional fins and associated plethora of openings offset in overlapping layers to create a centrifuge or cyclone effect for gases or particles passing through the filter. The fins and holes are offset from layer to layer within the wrap of the collar filter and are designed to immediately change the direction of the flames and burning particles relative to the input flame flow direction.

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.

An electronic circuit block including a voltage detection circuit from a high-temperature, high-pressure exhaust gas, a battery module includes: a battery stack in which a plurality of battery cells are stacked; a pair of end plates disposed at both end parts in a stacking direction of the battery stack; bind bar coupling the pair of end plates to fix the battery cells; and electronic circuit block on which the voltage detection circuit for detecting voltages of the battery cells is mounted, and electronic circuit block is disposed on a surface of end plate.

A battery pack includes a battery cell and a casing configured to receive the battery cell. The casing has a vent hole configured to allow gas generated in the battery cell to be discharged therethrough, and a sound generator installed in the vent hole so as to block the vent hole. The sound generator is configured to allow the gas to pass therethrough, and generate a sound by the flow of the gas when the gas is discharged from the casing through the vent hole.

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.
