Battery box and battery module

A battery module, comprising:

• a battery box, wherein the battery box comprise:
• at least two end plates;
• at least two side plates, wherein one of the at least two end plates is provided between two adjacent side plates of the at least two side plates, and wherein the at least two end plates and the at least two side plates are connected to one another to enclose a cavity of the battery box;
• and
• a plurality of welding members, wherein the plurality of welding members are formed by bending an end portion of a side plate of the at least two side plates or an end portion of an end plate of the at least two end plates multiple times, wherein the end portion of the side plate and the end portion of the end plate are configured to implement the connection of the at least two side plates and the at least two end plates to one another to enclose the cavity of the battery box;
• wherein:
• the plurality of welding members are configured to be welded to a corresponding side plate;
• the end portion of the end plate for enclosure is configured to bend twice to form a first welding member and a second welding member;
• and
• the first welding member is perpendicular to other parts of the end plate except the end portion, the second welding member is parallel to the first welding member, and the second welding member and the first welding member are attached to each other;
• and
• a plurality of battery cells stacked together and provided in the cavity.

An apparatus, comprising a battery module adapted to provide power for the apparatus, the battery module comprising:

• a battery box, wherein the battery box comprise:
