The shape of the through slot can be rectangular, trapezoidal, or other forms. The size and distribution density of the through slot are determined according to the specific size, material, and stress situation in the actual application scenario of the edge end plate 100. From the structural point of view, the reasonable distribution of the first through slot 140 can optimize the mass distribution without damaging the overall structural stability of the edge end plate 100, so that the edge end plate 100 can still effectively perform its functions while reducing weight.
[0039] In summary, the provision of the first through slot 140 on the edge end plate 100 reduces the weight of the edge end plate 100, which positively contributes to the lightweight of the entire battery end plate assembly.

[0041] In a specific embodiment, the first through slot 140 is a through slot structure on the edge end plate 100, which penetrates from one side to the other side of the edge end plate 100 in the vertical direction. The design of the first through slot 140 takes into account the mechanical properties and weight reduction requirements of the edge end plate 100. On the basis of ensuring that the edge end plate 100 can withstand various forces during the fixing of the battery cell module, external installation connection, and hoisting, the weight is reduced by removing part of the material. The shape of the through slot can be rectangular, trapezoidal, or other forms. The size and distribution density of the through slot are determined according to the specific size, material, and stress situation in the actual application scenario of the edge end plate 100. From the structural point of view, the reasonable distribution of the first through slot 140 can optimize the mass distribution without damaging the overall structural stability of the edge end plate 100, so that the edge end plate 100 can still effectively perform its functions while reducing weight.

[0044] In a specific embodiment, the second through groove 220 is a through groove structure formed on the spacing end plate 200, the second through groove 220 penetrating the entire thickness direction of the spacing end plate 200 and extending from one side to the other side. The design of the second through groove 220 meets the functional requirements of fixing the battery cell module, cooperating with the edge end plate 100 to maintain the stability of the battery cell module structure, and other functions, and achieves the purpose of weight reduction by removing part of the material. The shape of the second through groove 220 can have multiple choices, such as rectangle, circle, polygon, etc., and the size and distribution will comprehensively consider factors such as the material properties of the spacing end plate 200, the actual stress distribution, and the overall structure layout. Reasonably arranged second through grooves 220 can optimize the mass distribution of the spacing end plate 200, reduce the weight while ensuring that the mechanical properties of the spacing end plate 200 are not greatly affected, and can still effectively bear the force transmitted from the battery cell module.
[0045] In summary, the second through groove 220 provided on the spacing end plate 200 reduces the weight of the spacing end plate 200, which helps to realize lightweight design, and for some application scenarios with strict requirements on weight, can reduce the overall load and improve the performance and efficiency of related equipment. From the cost point of view, the second through groove 220 reduces the amount of material used and reduces production costs, especially in large-scale production, the cost savings are more significant.
