The present disclosure provides a battery module. The battery module includes a plurality of batteries that are stacked and two end plates disposed at two ends of the plurality of batteries in a stacking direction of the batteries. The battery module further includes a fixing strap, which includes a strap-shaped body and an elastic fixing part. The strap-shaped body surrounds the plurality of batteries and the end plates and defines a gap. The elastic fixing part is disposed in the gap and connected to the strap-shaped body. The elastic fixing part, together with the strap-shaped body, can provide an expansion space for the battery module with a certain restraint. In this way, the deformation of the battery module can be suppressed, and the battery module is protected from being damaged by a shear force of the strap-shaped body, thereby improving reliability of the battery performance.

The disclosure relates to a composite end plate and a battery module. The composite end plate comprises a first surface and a second surface, and comprises a rigid base plate comprising two ends and a rigid connecting plate extending in a height direction of the composite end plate. The rigid connecting plate and the rigid base plate are made of different materials. The rigid connecting plate comprises a first connecting segment, an intermediate transitional segment and a second connecting segment. The second connecting segment comprises a transferring section connected to the intermediate transitional segment and a free-end section. The two ends are fixedly connected to two respective rigid connecting plates. The first connecting segment and the free-end section are embedded in the rigid base plate. The transferring section can be fixedly connected to an external structural component. The composite end plate can be firmly connected to the side plate.

The present disclosure provides a battery module, which comprises a plurality of battery arrays, a first end plate, a second end plate and a separating plate. Each battery array comprises a plurality of batteries sequentially arranged in a longitudinal direction, the plurality of battery arrays are sequentially arranged in a transversal direction. The first end plate and the second end plate are respectively positioned at two ends of the plurality of battery arrays in the longitudinal direction. The first end plate has a passage. The separating plate is provided between two adjacent battery arrays, one end of the separating plate in the longitudinal direction is fixed with the second end plate, the other end of the separating plate in the longitudinal direction extends into the passage and is fixed with the first end plate. In the passage, the separating plate has a bending portion not parallel to the longitudinal direction.

The present disclosure relates to a composite end plate and a battery module. The composite end plate comprises a first rigid plate having a first surface and a second surface opposite to each other in a thickness direction of the first rigid plate, and comprising a first end portion, a first intermediate portion and a second end portion continuously distributed in a length direction of the first rigid plate; and a second rigid plate comprising a first free end, a second intermediate portion and a second free end continuously distributed in the length direction, wherein the first rigid plate and the second rigid plate are made of different materials, the second intermediate portion is disposed opposite to the first surface, the first free end is connected to the first end portion, and the second free end is connected to the second end portion.

The present application relates to the technical field of batteries and, particularly, relates to an end plate of a battery module and a battery module. The end plate of a battery module includes a main body and an energy absorbing body, the energy absorbing body includes an acting portion and a connecting portion, the acting portion protrudes in a direction from the main body toward a battery, and the acting portion is connected with the main body through the connecting portion. After the battery module is assembled, if the battery of the battery module expands and applies an expansion force to the end plate, then the energy absorbing body will deform elastically, so as to absorb the expansion force of the battery. Therefore, the end plate can prevent the housing of the battery module from failure, so as to improve structural strength of the battery module.

End plate of battery module and battery module

The present application relates to an end plate assembly of a battery module and a battery module. The end plate assembly includes an end plate and an energy absorbing component, the energy absorbing component is arranged between the end plate and a battery, the energy absorbing component includes a stress bearing plate and a bending plate, the bending plate and the stress bearing plate are connected with each other. After the battery module is assembled, if the battery of the battery module expands and applies an expansion force to the energy absorbing component, then the bending plate of the energy absorbing component will deform elastically, so as to absorb the expansion force of the battery. Therefore, the end plate of the end plate assembly will stress smaller expansion force, so as to prevent the battery module from failure, thereby improving structural strength of the battery module.
