A battery module comprising a housing, a venting assembly, a plurality of battery cells disposed in the housing, a printed circuit configured to control operations of the battery module, a vent chamber of the venting assembly, and a lid including the venting assembly. Each of the plurality of battery cells comprises a battery cell vent for venting gases from within the corresponding battery cell upward in a direction of the printed circuit. The vent chamber is disposed between the plurality of battery cells and the printed circuit. The vent chamber is configured to direct the gases vented from the battery cell vent toward an opening for venting the gases from the battery module. The lid is disposed over the plurality of battery cells and holds the printed circuit above the plurality of battery cells.

The present application provides a battery pack. The battery pack includes a box, the box being configured as a cavity structure; an exhaust channel arranged at the bottom of the box; and a plurality of battery cells, the plurality of battery cells being stacked and housed in the cavity structure of the box, and the plurality of battery cells being located on an end face of the exhaust channel facing away from the bottom of the box, and an end face of each of the battery cells facing the exhaust channel being provided with an explosion-proof valve, where a structural layer of the exhaust channel facing the explosion-proof valve is provided with a weakened zone, and when thermal runaway occurs in any battery cell, a gas in the battery cell is capable of being collected into the exhaust channel via the weakened zone and discharged.

The technology disclosed herein relates to, at least in part, an enclosure vent assembly. A vent body defines a vent cavity, a first axial end, a second axial end, circumferential threads positioned towards the second axial end, and a sealing surface. The sealing surface surrounds the vent cavity and faces the second axial end. A vent is disposed in the vent body, wherein the vent extends across the vent cavity. A vent mount defines a mount opening, mating threads configured to releasably engage the circumferential threads, a facing surface about the mount opening configured to oppose the sealing surface, and a fastening feature. The fastening feature is configured to rotatably fix the vent mount to a housing.

A valve, a battery and a power consumption device are disclosed, the valve includes a valve body, a barrier, a first unidirectional valve core and a second unidirectional valve core. The valve body includes a fluid channel; the barrier is disposed in the fluid channel, and separates the fluid channel into a first cavity and a second cavity, the barrier is provided with a first through hole and a second through hole communicating the first cavity and the second cavity; the first unidirectional valve core is configured to close or open the first through hole; the second unidirectional valve core is configured to close or open the second through hole, opening directions of the first unidirectional valve core and the second unidirectional valve core are opposite. The valve is compact and capable of implementing a bi-directional flow of fluid.

A containment system (100) includes a housing (106). A battery pack (104) is situated within the housing. One or more ports (114) are disposed along a surface of the housing. An effluent containment pouch (108) is coupled to the surface of the housing. The effluent containment pouch spans the one or more ports. The effluent containment pouch expands when an electrochemical cell (105) experiences a thermal runaway condition, capturing expelled effluent (116).

A valve device and an assembled battery according to which even if the valve device operates, deterioration of an outer layer of a storage body is unlikely to be accelerated. The valve device is attached to a first storage body that stores a battery. The valve device includes an attachment part, a valve device main body, and a gas passage part. The attachment part is attached to the first storage body. The valve device main body reduces pressure inside the first storage body in a case where the pressure increases due to gas produced inside the first storage body. The gas passage part is between the attachment part and the valve device main body, and allows gas that passes through the attachment part to pass through the valve device main body. The valve device main body is located outward of an outer periphery of the first storage body.
