Abstract: This application relates to the field of battery technology, and in particular, to a box assembly, a battery module, a battery, and an electrical device. The box assembly may include at least a partition piece and two end plates. In the box assembly disclosed herein, a stress relief piece may be disposed at two ends of a main body of the partition piece. The main body may be connected to the end plate by use of the stress relief piece. A corner may be formed between the stress relief piece and the main body. In this way, when the battery module is subjected to stress, at least a part of the stress can be relieved through the corner formed between the stress relief piece and the main body.

Abstract: This application relates to an end plate of a battery module as well as a battery module. The end plate includes a body and a connector connected to the body. The body is fixedly connected to a side plate through the connector. The connector is provided with a light shielding part. The light shielding part is located on a side of the connector that faces the side plate, and located between the connector and the side plate. In the end plate as well as the battery module according to this application, the end plate includes the body and the connector, and weldability between the body and the side plate is improved by the connector. The connector includes a light shielding part that avoids the problem of battery explosion caused by a laser beam radiated to a battery inside the battery module, and improves safety performance of the battery.
