The power switch 203 is located on one side of the battery box cover and is electrically connected to the BMS in the battery box through the harness 3, so as to realize the power on or off function of the energy storage battery. When the power is on, the energy storage battery can be charged and discharged, and when the power is off, the energy storage battery cannot be charged and discharged.

[0045] The first cover 1 and the second cover 2 are both used for detachable connection with the battery case, wherein the first cover 1 and the second cover 2 are detachable connected with different parts of the battery case. In the embodiment of the utility model, the first cover 1 is relatively large in size, and the peripheral side of the first cover 1 is used for detachable connection with the side of the battery case. The second cover 2 is relatively small in size. The second cover 2 is arranged at the opening 10 on the first cover 1 and is detachably connected with the inner side of the battery case.

[0048] Specifically, a cable tie 22 for restraining the wiring harness 3 is provided on the second cover body 2. After the wiring harness 3 is connected to the electrical connection component 20 on the second cover body 2, or before the wiring harness 3 is connected to the electrical connection component 20, the wiring harness 3 can be restrained by passing through the cable tie 22, thereby improving the neatness of the wiring harness 3 and making it easier to subsequently connect the second cover body 2 to the battery box and to connect the wiring harness 3 to the BMS and the battery module.

[0049] Optionally, refer to Figure 4 and Figure 5 The second cover body 2 includes: a bracket 23, the bracket 23 is used to be detachably connected to the battery box, and the tie 22 is arranged on the bracket 23; a body 24, the body 24 is installed on the bracket 23, and the electrical connection component 20 is arranged on the body 24.

[0050] Specifically, the second cover 2 includes a bracket 23 and a body 24. The bracket 23 can be formed by bending a hard sheet metal part, or by assembling and connecting a hard alloy or a metal plate, and has good strength and rigidity, and is used to support and fix the body 24.

The sealing ring is sleeved on the peripheral side of the body 24. In order to prevent the sealing ring from sliding relative to the peripheral side of the body 24, a slot that matches the shape and size of the sealing ring can be opened on the peripheral side of the body 24, and then the sealing ring is clamped in the slot. The sealant can be directly filled in the gap between the peripheral side of the body 24 and the inner wall of the opening 10. After the second cover body 2 is embedded in the opening 10 and connected to the battery box, the sealing member 25 can achieve the sealing of the gap between the peripheral side of the body 24 and the inner wall of the opening 10, thereby improving the sealing effect and the waterproof and dustproof effect of the battery box cover. Of course, the sealing member 25 can also be other structural forms, which are not limited to this embodiment of the utility model. Furthermore, the size of the bracket 23 can be larger than the size of the body 24, such as Figure 4 and Figure 6 As shown, along the height direction of the battery box cover, that is Figure 4 and Figure 6 In the Z direction, the projection of the body 24 is located within the projection of the bracket 23 , so that the bracket 23 can limit the body 24 along the Z direction to prevent the body 24 from being separated from the opening 10 .

The base 5 has a receiving cavity 50, and the battery module 4 is placed in the receiving cavity 50. The base 5 can play a certain protective role on the battery module 4 in the receiving cavity 50. Fig. 9 As shown, the base 5 is composed of a tray 55, a left side plate 51, a right side plate 52, a front side plate 53, and a rear side plate 54. The tray 55 is used to support the battery module 4. The left side plate 51, the right side plate 52, the front side plate 53, and the rear side plate 54 are arranged around the tray 55 and are fixedly connected to the tray 55. The left side plate 51, the right side plate 52, the front side plate 53, and the rear side plate 54 together with the tray 55 define a receiving cavity 50. During the assembly process, the left side plate 51, the right side plate 52, and the rear side plate 54 can be assembled and connected with the tray 55 respectively to form an upper and one side open receiving cavity 50, wherein the upper part refers to the side away from the tray 55, and then the battery module 4 is pushed into the receiving cavity 50 from the front side plate 53, and then the front side plate 53 is assembled and connected with the tray 55, which is more conducive to improving the stability of the battery module 4 installation process. Of course, in other embodiments, the tray 55, the left side plate 51, the right side plate 52, the front side plate 53, and the rear side plate 54 of the base 5 can be directly fixed by welding to form an upper open accommodating cavity 50, and then the battery module 4 is vertically placed into the accommodating cavity 50 from the top of the accommodating cavity 50.
