    摘要： 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.

    摘要： An accumulator may include a housing with at least two mutually opposite housing walls, accumulator cells arranged between the housing walls and following one another in a stacking direction, and at least one intermediate piece arranged in the housing between at least one of the accumulator cells and one of the housing walls and that retains the accumulator cells in the housing. At least one intermediate piece may be configured as a mutable intermediate piece in such a way that the mutable intermediate piece may be changeable between a first state having a first thickness extending in a spacing direction between the associated housing wall and the associated at least one of the accumulator cells, and a second state having a second thickness extending in the spacing direction, wherein the second thickness may be greater than the first thickness. In the state in which the mutable intermediate piece and the accumulator cells may be arranged in the housing, the mutable intermediate piece may be changed into the second state.
