A battery pack assembly includes a housing, a battery cell assembly, and a fan. The housing having a plurality of sides and defining an internal cavity. The battery cell assembly positioned in the internal cavity. The battery cell assembly includes a plurality of battery cells and a frame supporting the battery cells. The frame includes a first support member, a second support member, and a plurality of leg members connecting the first support member and the second support member. The first support member and the second support member each has a body extending between a first edge and a second edge opposite the first edge. The body defines a plurality of openings configured to align with one of the battery cells. The fan is configured to circulate air within the housing and through the battery cell assembly.

A cooling structure includes a power storage stack including power storage cells, first and second end plates, a refrigerant supply path for supplying refrigerant, and first paths each provided in a clearance between two of the adjacent power storage cells. The first end plate is configured to form a second path communicating with the refrigerant supply path in a clearance between a first end of the power storage stack and the first end plate. The second end plate is configured to form a third path communicating with the refrigerant supply path in a clearance between a second end of the power storage stack and the second end plate. The power storage stack is cooled to have a temperature distribution in which the power storage cells disposed on the second end side have temperatures higher than the temperatures of the power storage cells disposed on the first end side.

Embodiments of this application provide a box, a battery, and an apparatus, and relate to the field of battery technologies. The box is provided with a discharge hole, and the discharge hole is configured to discharge, from inside the box, flame produced when thermal runaway occurs in a battery cell. The box is further provided with a fire extinguishing member that is configured to extinguish the flame for cooling when the flame passes through the discharge hole. In this application, the discharge hole and the fire extinguishing member are arranged in the box, so that when the flame produced when thermal runaway occurs in the battery cell passes through the discharge hole, the fire extinguishing member can release a fire extinguishing agent to extinguish the flame for cooling. This prevents the flame from being discharged from inside the box through the discharge hole, thereby improving safety performance of the battery.
