1. A battery box, comprising: a box body comprising a closed accommodation space; and a first battery group accommodated in the closed accommodation space, wherein the first battery group comprises:
a first battery row, wherein the first battery row comprises a plurality of batteries arranged side by side along a width direction, an explosion-proof valve is disposed on the top of each battery, and all explosion-proof valves of the first battery row form a first explosion-proof valve row;
a first guide plate, configured to extend along the width direction and be sealed and disposed above the first explosion-proof valve row, wherein the first guide plate and an upper surface of the first battery row form a first path extended along the width direction; and
a first end plate, disposed on one side in the width direction of the first battery row and provided with a first recess, wherein the first recess is located below the first guide plate in a height direction and communicates with one end of the first path, the first recess is recessed inwardly from a surface on a side facing away from the first battery row and extends to an upper surface of the first end plate in the height direction so as to communicate with the first path formed by the first guide plate, and an opening is disposed at a position corresponding to the first recess of the box body, when an explosion-proof valve of the first explosion-proof valve row is broken due to gas production inside the battery, emissions discharged from the broken explosion-proof valve is transmitted by the first path to a space between the first recess and the box body, and then discharged to the outside of the box body through the opening corresponding to the first recess of the box body; wherein
the battery box further comprises: a sealing member, wherein the sealing member is configured to seal an opening corresponding to the box body and is capable of being damaged by the emissions to open the opening.
