The battery pack includes the battery module M according to the present invention. The battery modules M can be accommodated in the box body, the number of the battery modules M is one or more, and the plurality of battery modules M are arranged in the box body. The type of the case is not limited, and the case may be a frame-shaped case, a disc-shaped case, a box-shaped case, or the like, and specifically, the case may include a lower case that houses the battery module M and an upper case that covers the lower case.
Referring to fig. 1 to 3, a battery module M according to the present invention includes a first battery cell 1, a second battery cell 2, a dam structure 3, and an insulating paste (not shown). The battery module M may further include a strap 4 and an end plate 5.

Referring to the example shown in fig. 3, a dimension D1 of the dam structure 3 in the height direction H is smaller than the smallest dimension of the dimension D1 of the first battery cell 1 in the height direction H and the dimension of the second battery cell 2 in the height direction H, and a dimension D2 of the dam structure 3 in the longitudinal direction L is smaller than the smallest dimension of the dimension D2 of the first battery cell 1 in the longitudinal direction L and the dimension of the second battery cell 2 in the longitudinal direction L.

Size D1 of glue blocking structure 3 along height direction H is less than size D1 of first battery unit 1 along height direction H, and size D2 of glue blocking structure 3 along vertical L is less than size D2 of first battery unit 1 along vertical L, can avoid glue overflowing because of the too big size along height direction H of expansion after glue blocking structure 3 is compressed. Further, in a plane perpendicular to the transverse direction T, projections of the glue blocking structure 3 in the plane are located in a range of projections of the first battery unit 1 and the second battery unit 2 in the plane, so that the glue blocking structure 3 is reliably ensured to function, and glue overflow caused by improper arrangement positions of the glue blocking structure 3 is prevented.
As shown in fig. 2 to 4, the frame 31 of the glue blocking structure 3 has a top wall 311, a bottom wall 312 and two side walls 313. The top wall 311 and the bottom wall 312 are opposed in the height direction H, and the two side walls 313 are opposed in the longitudinal direction L. The glue filling holes 31a are preferably arranged on the top wall 311, the number of the glue filling holes 31a can be one or more, and the arrangement positions and the number of the glue filling holes 31a are not limited and can be determined according to specific working conditions. The enclosure frame 31 can be further provided with an observation hole 31b for observing the glue filling amount, and gas generated in the process of glue filling in the accommodating cavity 32 can be led out, so that the firm degree of the insulation glue bonding is prevented from being influenced by the gas. The number of the observation holes 31b is not limited and may be one or more.
As shown in fig. 2 to 4, in order to make the glue filling uniformity better and to make the glue applied to the battery uniform, the receiving cavity 32 may be divided into a plurality of sub-cavities 321 by the partition 33, and each sub-cavity 321 receives the insulating glue. The plurality of the glue filling holes 31a are provided, and each sub-cavity 321 communicates with the corresponding glue filling hole 31 a. Specifically, each sub-cavity 321 may be communicated with a corresponding one of the glue filling holes 31a (as shown in fig. 2 to 5), and the distance between adjacent glue filling holes 31a is determined according to the length of the battery units (the first battery unit 1 and the second battery unit 2) along the longitudinal direction L, so that the minimum number of glue filling times needs to be ensured, and thus the glue filling efficiency is improved. The sub-cavities 321 can also be communicated with a plurality of corresponding glue filling holes 31a so as to improve the glue filling efficiency. The observation holes 31b are similar to the glue filling holes 31a, and each sub-cavity 321 can be communicated with a corresponding observation hole 31b (as shown in fig. 2 to 5), and each sub-cavity 321 can also be communicated with a corresponding plurality of observation holes 31b, so that the glue filling amount can be observed from a plurality of angles and positions. Preferably, each sub-cavity 321 corresponds to each adjacent two sides of the first battery 11 in the first battery unit 1 along the transverse direction T and each adjacent two sides of the second battery 21 in the first battery unit 2 along the transverse direction T, because the number of the first battery 11 and the second battery 21 corresponding to each sub-cavity 321 is too large, the size of each sub-cavity 321 along the longitudinal direction L is required to be larger, the battery gluing uniformity is affected, the insulating glue is easily distributed unevenly in each sub-cavity 321, so as to reduce the connection strength between the first battery unit 1 and the second battery unit 2, and the size of each sub-cavity 321 along the longitudinal direction L is larger, after the glue blocking structure 3 is compressed, each position of the corresponding surrounding frame 31 surrounding each sub-cavity 321 along the longitudinal direction L is easily stressed unevenly, the position which is compressed weaker is not tightly attached to the first battery unit 1 and the second battery unit 2, thereby causing the insulating paste to overflow from the surrounding frame 31. If the sub-cavities 321 are made to correspond to the lateral sides of the first batteries 11 in the first battery unit 1 along the transverse direction T and the lateral sides of the second batteries 21 in the first battery unit 2 along the transverse direction T, the number of times of the glue filling operation is increased, and the glue filling efficiency is reduced. After the completion is to keeping off gluey structure 3 encapsulating, it is 0.5 ~ 2mm to accept the glue thickness of chamber 32 internal insulation along horizontal T to guarantee the stability and the intensity of bonding.
The viscosity of the insulating glue is preferably less than 10000cps to ensure good fluidity of the insulating glue, and if the fluidity of the insulating glue is poor (the viscosity is greater than 10000cps), the glue filling pressure of the glue filling from the glue filling hole 31a by using a glue filling device (such as a glue spreader) needs to be increased.
As shown in fig. 1, the tie 4 binds the first battery unit 1, the second battery unit 2 and the glue blocking structure 3 together to ensure the connection strength between the first battery unit 1 and the second battery unit 2 and ensure the reliable grouping of the battery modules M.

In the battery module M according to the present invention, the glue blocking structure 3 is disposed between the side surface of the first battery unit 1 along the transverse direction T and the side surface of the second battery unit 2 along the transverse direction T, the accommodating cavity 32 of the glue blocking structure 3 and the mutually facing side surfaces of the first battery unit 1 and the second battery unit 2 define a glue applying area, and the accommodating cavity 32 is filled with the insulating glue through the glue filling hole 31a disposed on the enclosing frame 31, so that the first battery unit and the second battery unit are bonded together. Therefore, the glue coating on the side face of the battery is easy to realize, and the overflow of the glue can be effectively prevented due to the enclosing barrier of the enclosing frame 31.
