The outer shell of each energy storage component 1 is in direct contact with the bus bracket 2. Optionally, the energy storage component 1 is in the shape of a rectangular parallelepiped, and the two large surfaces of the energy storage component 1 are arranged facing the inner wall surfaces of the two large surfaces of the packaging component. A small distance is formed between the large surface of the energy storage component 1 and the inner wall surface of the packaging component, and the energy storage component 1 is in contact with the bus bracket 2, and the bus bracket 2 is in contact with the packaging component. Some components in the packaging component and the bus bracket 2 are made of thermally conductive materials. When the heat generated by the energy storage component 1 can be transferred to the bus bracket 2 and the packaging component, the heat is dissipated outside the packaging component, thereby effectively ensuring the heat dissipation effect of the energy storage component 1, and reducing the risk of large temperature differences between the energy storage components 1, resulting in large pressure differences in the battery pack, low capacity, and failure of the battery cell 101.

[0045] Furthermore, the bus bracket 2 includes: a support plate 201 and a support frame 202, wherein the number of the support plates 201 is multiple, the multiple support plates 201 are arranged in sequence and spaced apart, and the multiple support plates 201 are arranged in parallel, and the distance between any two adjacent support plates 201 is the same. The support frame 202 is in the shape of an elongated strip, the number of the support frames 202 is two, the two support frames 202 are arranged in parallel, and each support plate 201 is arranged perpendicular to the support frame 202.

The other support frame 202 is arranged at the other end of the support plate 201, and the other end of the support plate 201 is connected to the inner wall surface of the support frame 202. The multiple support plates 201 and the two support frames 202 together form a frame structure. The space defined between any two support plates 201 and the two support frames 202 is the storage compartment for accommodating the energy storage assembly 1.
