To the position adjustment of single row battery core module 41 in first direction X, can realize through the cooperation of spout and slide rail. For example, each stacking mechanism 21 may include a first carrier plate 211 and a second carrier plate 212, the first carrier plate 211 and the second carrier plate 212 may be both elongated plates, and the movement between the first carrier plate 211 and the second carrier plate 212 may be realized by sliding of a sliding rail and a sliding groove.

It can be understood that the sliding directions of the first sliding rail 2120 and the first sliding groove 2110 are parallel to the first direction X, so that the position of the first carrier plate 211 relative to the second carrier plate 212 in the first direction X can be adjusted to adjust the position of the adjacent single row cell module 41 in the first direction X. Of course, the movement between the first carrier plate 211 and the second carrier plate 212 can be realized by other structure cooperation, such as a screw transmission mechanism, which is not illustrated here. In addition, the number of the first sliding grooves 2110 may be set as required, for example, one first sliding groove 2110 is respectively disposed at symmetrical positions of two ends of the first carrier 211 to improve the stability of the first carrier 211 during movement. The number of the first slide rails 2120 corresponds to the number of the first slide grooves 2110.

The number of the third chutes 2152 may be the same as that of the first chutes 2110, and thus, the description thereof is omitted.

Then pile up second single row battery core module 41, third single row battery core module 41, fourth single row battery core module 41 and fifth single row battery core module 41 in proper order, and second single row battery core module 41 uses first single row battery core module 41 as the benchmark of location to analogize, accomplish piling up of five single row battery core modules 41.

It should be noted that the structure and the number of the liquid cooling plate 410 in the first single-row cell module 41 are different from those of the liquid cooling plates 410 in the remaining four single-row cell modules 41. For example, the first single-row cell module 41 may include two first liquid cooling plates 410a and two second liquid cooling plates 410b, which are oppositely disposed, where the first liquid cooling plates 410a are in an L-shaped structure, the second liquid cooling plates 410b are in a T-shaped structure, the first liquid cooling plates 410a are used for being connected to the reference positioning element 22, and the second liquid cooling plates 410b are used for being connected to the second single-row cell module 41. The second single-row battery cell module 41, the third single-row battery cell module 41 and the fourth single-row battery cell module 41 may all include the second liquid cooling plate 410b, and the opposite side of the second single-row battery cell module 41 on which the second liquid cooling plate 410b is disposed is connected to the side of the first single-row battery cell module 41 on which the second liquid cooling plate 410b is disposed. That is, the second single-row cell module 41 is positioned with reference to the second liquid cooling plate 410b of the first single-row cell module 41. The fifth single-row cell module 41 may include a first liquid cooling plate 410a, and the first liquid cooling plate 410a of the fifth single-row cell module 41 is disposed on the opposite side of the first liquid cooling plate 410a of the first single-row cell module 41. Because the second liquid cooling plate 410b needs to connect two rows of cells 412 on two sides thereof, that is, the second liquid cooling plate 410b can provide heat dissipation for the two rows of cells 412. To second single row battery cell module 41, third single row battery cell module 41 and fourth single row battery cell module 41, the both sides of every single row battery cell module 41 all are provided with second liquid cooling board 410b.

The stacking process of the five single-row battery cell modules 41 may be as follows: in the first stage, the third driving member 213c in the stacking mechanism 21 drives the stacking mechanism 21 to move upward along the third direction Z, the single-row cell module 41 and the hoisting plate 23 thereof are placed on the first carrier plate 211 of the stacking structure 21 together, the first limiting block 217a and the second limiting block 217b limit the position of the liquid cooling plate 410 in the single-row cell module 41 together, the positioning pin 218b positions the position of the hoisting plate 23, the positioning block 218a positions the positioning end of the single-row cell module 41, after the state of the single-row cell module 41 is maintained, the third driving member 213c drives the whole body to descend to the height reference surface of the height reference seat 219, so that the bottom of the liquid cooling plate 410 is located on the height reference surface, and the state positioning before the whole single-row cell module 41 is stacked is completed.

In the second stage, the second driving element 213b drives the second slide rail 2150 and the second slide slot 2122 to move to the set value in the second direction Y and then stop, so as to ensure that the position in the second direction Y is aligned with the length of the reference positioning element 22. Then, the first driving member 213a drives the first slide rail 2120 and the first slide groove 2110 to move in the first direction X to be attached to the contour groove of the reference positioning element 22 and then stop. So far, the first single-row cell module 41 is stacked.

In the third stage, a second single-row cell module 41 is stacked by repeating the steps in the third stage, except that the positioning reference is not the reference positioning member 22, but the first stacked single-row cell module 41. The second single-row battery cell module 41 is close to the first single-row battery cell module 41, and after the preset position is reached, the distance between the two single-row battery cell modules 41 can be adjusted by the adjusting tooth bar assembly 214, so that the accuracy of the relative position is ensured. According to the third step, the second single-row cell module 41 can be stacked.

The fourth stage is to stack up the third single-row cell module 41, the fourth single-row cell module 41, and the fifth single-row cell module 41 in sequence by repeating the steps of the third stage. Thus, the grouping scheme is completed.

Finally, the assembly of the edge beam 42 may be performed, whereby the battery pack 4 is also completely assembled.
