The connection board 20 is disposed between the circuit substrate 10 and the battery cell, so as to realize insulation between the circuit substrate 10 and the battery cell.

Fig. 2 is an enlarged schematic view of the structure a shown in fig. 1. As shown in fig. 2, the connection plate 20 is provided with mounting holes 21 in the thickness direction thereof. The thickness direction of the connection plate 20 is identical to the thickness direction of the circuit board 10, and may be the height direction of the battery device. The mounting hole 21 is a through hole in the thickness direction of the connection plate 20. The mounting hole 21 may be a rectangular hole. The length direction of the mounting hole 21 may be the length direction of the circuit substrate 10. The acquisition terminal 11 is used for fixing the acquisition unit. The collection terminal 11 extends into the mounting hole 21 along the longitudinal direction of the circuit board 10. The collecting terminal 11 is fixed to the surface of the collecting terminal 11 and fitted into the mounting hole 21. The collector is not shown in figure 2, but is obscured. Because the circuit substrate 10 is disposed on one side of the connection board 20 away from the battery cell, and the collector needs to be disposed close to the battery cell, the collecting terminal 11 will bend when extending into the mounting hole 21, so as to penetrate into the mounting hole 21 and be disposed close to the battery cell.
