Referring to fig. 9, the abutting rib 40 may also be configured in an elongated shape. Of course, the abutting ribs 40 may be formed in a triangular or elliptical shape in cross section.

In one embodiment, the distance between the abutting ribs 40 between two adjacent spacers 60 may be set to be the same or different. Namely: on the surface of one side of the edge strip 30 facing the battery cell 21, the distances between the abutting ribs 40 arranged between two adjacent spacers 60 may be the same or different; the distances between the abutment ribs 40 provided on the side surfaces of the adjacent two spacers 60 facing each other may be set the same or may be set different; the distance between the abutment ribs 40 provided at the positions of the support regions 80 corresponding to the housing 20 and/or the partition 50 may be the same or different. Of course, the distance between two adjacent abutment ribs 40 on one edge strip 30 is the same as the distance between two adjacent abutment ribs 40 at corresponding positions on the other edge strip 30. Of course, the distance between two adjacent abutting ribs 40 on one edge strip 30 and the distance between two adjacent abutting ribs 40 at the corresponding position on the other edge strip 30 may also be different.

In one embodiment, the battery case 100 further includes a cover plate 10, the cover plate 10 is disposed on the casing 20 to cover the cavity 70, and the battery cell 21 may be covered inside the casing 20. Also be equipped with butt muscle 40 on the apron 10 towards one side surface of electric core 21, when the apron 10 lid closes on casing 20, the butt muscle 40 on the strake 30 and the butt muscle 40 on the apron 10 butt electric core 21 simultaneously in casing 20 for electric core 21 places more firmly in casing 20.

In one embodiment, the abutting ribs 40, the housing 20, the partition 50 and the spacer 60 are integrally formed, so that the structure strength is high, the processing and the manufacturing are convenient, and the subsequent use can be facilitated. In some embodiments, the abutment ribs 40 may be welded to the edge bars 30, the housing 20, the partition 50, or the spacer 60.

Referring to fig. 1 and fig. 2, an embodiment of the present application provides a battery pack, where the battery pack includes a battery cell 21 and a battery case 100 according to any of the embodiments, and the battery case 100 is adopted to make the battery cell 21 more stably placed, the battery pack is more stably used, and the safety performance is higher.

Referring to fig. 1 and fig. 2 together, an embodiment of the present application provides an energy storage power supply, which includes the battery pack of the above embodiment, and the energy storage power supply is more convenient to use and has higher safety performance.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
