A power storage pack includes: at least one storage device including a gas discharging part that discharges a gas produced inside; a porous member that has a structure in which a plurality of fire extinguishing agent grains are collected and has an air gap inside; and a case that stores the storage device and the porous member. Each fire extinguishing agent grain is a collection of a plurality of fire extinguishing agent powders, and the porous member is provided such that the gas flows in the air gap.

A battery includes a protective box provided with a guiding channel and a plurality of battery cells in the protective box. The plurality of battery cells include a first battery cell and a second battery cell adjacent to each other. The first battery cell includes a pressure relief end provided with a pressure relief mechanism. The pressure relief mechanism is configured to actuate release of internal pressure of the first battery cell in response to the internal pressure or an internal temperature of the first battery cell reaching a threshold. The guiding channel is configured to guide emissions released from the pressure relief mechanism. The pressure relief end of the first battery cell is staggered with one end of the second battery cell that is close to the pressure relief end, in a direction leaving the guiding channel.

A battery pack includes a cell assembly unit including a plurality of battery cells and a bus bar configured to electrically connect the plurality of battery cells, a frame unit accommodating the cell assembly unit, and a bracket unit fixing the cell assembly unit to the frame unit. The bracket unit and the frame unit form a flow path through which a gas is discharged. A reverse flow prevention member is disposed between the bus bar and the bracket unit. The reverse flow prevention member includes a plurality of gas permeation holes, each of which extends from one end facing the bus bar and leads to another end facing the flow path.

A battery module includes a lower housing and a plurality of battery cells. The plurality of battery cells are electrically coupled together to produce a voltage. The module also includes an assembly disposed over the battery cells and coupled to the lower housing. The assembly may include a lid and a plurality of bus bar interconnects mounted on the lid. The module also includes a printed circuit board (PCB) assembly disposed on and coupled to the assembly. The PCB assembly may include a PCB. The module also includes a cover disposed over and coupled to the lower housing to hermetically seal the battery module. Also disclosed is a method of manufacturing the battery module.

A battery includes a battery cell, a fire prevention chamber, a collection chamber, and an isolation member. The battery cell includes a pressure relief mechanism configured to actuate release of internal pressure of the battery cell in response to the internal pressure or internal temperature of the battery cell reaching a threshold. The fire prevention chamber is configured to accommodate a fire prevention medium and constructed to release the fire prevention medium during actuation of the pressure relief mechanism. The collection chamber is located at a side of the fire prevention chamber farther away from the battery cell and configured to collect emissions from the battery cell during actuation of the pressure relief mechanism. The isolation member is configured to isolate the fire prevention chamber from the collection chamber and constructed to allow passage of the emissions during actuation of the pressure relief mechanism.

Provided is a battery module and battery rack having enhanced fire safety features. The battery module includes a swelling/pressure sensor that detects swelling of a battery cell. An output signal of the sensor is used to halt operation of a battery rack/battery system containing the battery module and prevent charging and discharging of the battery module. In an embodiment, the battery module uses an AC-to-AC power supply to provide AC frequency power for balancing battery cells of the battery module. In an embodiment, the battery rack includes an internal water fire suppression system that provides battery cooling in the event of a battery cell fire to prevent the spread and/or reigniting of the fire.

Embodiments of the present application provide a battery, a power consumption apparatus, and a method and apparatus for producing a battery. The battery includes: a battery cell, provided with a pressure relief mechanism, the pressure relief mechanism being configured to be actuated when an internal pressure or temperature of the battery cell reaches a threshold, to relieve the internal pressure; a bus component, configured to be electrically connected to the battery cell; an electrical cavity, configured to accommodate the battery cell and the bus component; a collecting cavity, configured to collect emissions from the battery cell when the pressure relief mechanism is actuated; and a sealing structure, disposed in an airflow path formed between the pressure relief mechanism and a wall of the electrical cavity and configured to prevent the emissions from reaching the bus component when the pressure relief mechanism is actuated.
