There is a spacing space between the adapter board 400 and the control board 300. The adapter board 400 is provided with a first voltage-dividing connector 420. The control board 300 is provided with a second voltage-dividing connector 310 that is plugged and matched with the first voltage-dividing connector 420, so that the adapter board 400 can transmit the voltage information of the battery cell 500 to the control board 300. After the upper cover 200 is covered on the lower shell 100, the control board 300, the adapter board 400 and the battery cell 500 are all enclosed in the space surrounded by the upper cover 200 and the lower shell 100. The first voltage-dividing connector 420 and the second voltage-dividing connector 310 both have a conductor and an insulator. After the first voltage-dividing connector 420 and the second voltage-dividing connector 310 are plugged in, the conductors of the two are connected, and the insulators of the two are in contact with each other. The control board 300 and the adapter board 400 transmit voltage information through the cooperation of the first voltage-dividing connector 420 and the second voltage-dividing connector 310, avoiding the risks of battery failure and fire caused by the disordered wiring of the voltage-dividing harness and the short circuit of the voltage-dividing wire during long-term use, thereby improving the battery life and safety, making the battery more reliable, and reducing the maintenance cost of the battery.

[0026] like Figure 1 , 3 As shown in Figures 5 and 6, a mounting cavity 110 is provided on the side wall of the lower shell 100, an emergency switch 111 is provided in the mounting cavity 110 and connected to the control board 300, a switch cover 112 is provided at the outer end opening of the mounting cavity 110, a valve cap 113 and a waterproof breathable sticker 114 are provided on the switch cover 112, and the waterproof breathable sticker 114 covers the valve cap 113.

The first fixing block 211 and the second fixing block 121 are clamped on the first fixing seat, the first fixing block 211 has a first recess 212, the second fixing block 121 has a first protrusion 122, the first protrusion 122 is embedded in the first recess 212, and a waterproof sealant is provided in the first installation cavity.

[0028] During installation, first fix the first fixing block 211 on the first base 210, and the second fixing block 121 on the second base 120. Part of the first threading hole is located on the first base 210, and part of the first threading hole is located on the second base 120. The lead wire of the discharge plug 610 is placed on the first threading hole on the second base 120. After the upper cover 200 is covered, the first fixing block 211 and the second fixing block 121 jointly constrain the lead wire. The cooperation of the first protrusion 122 and the first recess 212 can reduce the relative movement of the first fixing block 211 and the second fixing block 121, improve the stability of the first threading hole, and reduce damage to the lead wire. The waterproof sealant can prevent external liquid from entering the lower shell 100 from this position, thereby improving the reliability and safety of battery use.

The basic functions and effects of the third fixing block 221 and the fourth fixing block 131 are consistent with those of the first fixing block 211 and the fourth fixing block 131.

[0030] like Figure 4 As shown, a first foam 510 is disposed between the battery cell 500 and the inner wall of the lower shell 100, and a second foam 520 is disposed between each battery cell 500. Figure 7 As shown, in this embodiment, a second foam 520 is provided between some adjacent battery cells 500. Adding the second foam 520 between the battery cells 500 in the thickness direction can reserve a certain expansion space for the battery cells 500, which can reduce the battery structure failure caused by the expansion of the battery cells 500, improve the battery safety performance, and reduce the failure risk caused by the expansion of the battery cells 500 during use.

[0031] Furthermore, the battery cell 500, the adapter board 400, and the control board 300 are fixed in the lower shell 100 by glue filling. This increases the vibration resistance and fire resistance of the battery and reduces the failure risk of the battery cell 500 caused by water ingress.
