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.

A battery pack includes a pack housing; a plurality of battery modules; a water tank connected to the plurality of battery modules; a coolant tube including a main tube connected to the water tank, a plurality of supply tubes configured to connect the main tube and the battery modules to each other, and a bypass tube connected to the main tube at a point above a supply tube located at a top end among the plurality of supply tubes and at a point below a supply tube located at a bottom end; at least one sensor installed in the pack housing to detect a thermal runaway phenomenon generated in at least a part of the plurality of battery modules; and a controller configured to output a control signal for introducing a coolant into the battery module through the coolant tube when a thermal runaway phenomenon is detected by the sensor.
