Alternatively, the first mounting portions 131 are provided in plural and uniformly distributed on the side edge of the first liquid cooling element 13 in the longitudinal direction, so that a plurality of positioning points can be provided for the first liquid cooling element 13, and the positioning stability is improved. It will also be appreciated that a plurality of first mounting portions 131 may be arranged in a uniform distribution across the width of the first liquid cooling element 13. The number of the first mounting portions 131 may be adaptively adjusted according to the length and width dimensions of the first liquid cooling element 13, and is not particularly limited herein.
In this way, the first liquid cooling element 13 is generally of a thin plate structure and made of an aluminum material which is easily extruded and deformed.

After the battery module 121 on the first side 13a is assembled, the battery module 121 on the first side 13a is fastened to the case 11 by the fourth fastening member 174, so that the battery module 121 on the second side 13b can be assembled later.
Note that, the battery pack 1 of the embodiment of the present application has a two-layer structure. The first liquid cooling element 13 and the second liquid cooling element 16 have the same structure, and although the first liquid cooling element 13 is also provided with an avoidance groove, the avoidance groove of the first liquid cooling element 13 does not have a connection function. When the battery pack 1 of the embodiment of the present application has three or more layers, the avoidance groove on the corresponding first liquid cooling element 13 participates in the connection.
