[0028] The present embodiment provides a battery pack that is easy to install and disassemble. The battery pack that is easy to install and disassemble realizes the rapid disassembly of the connector panel 20 and the MSD panel 30 on the battery pack, thereby facilitating rapid maintenance of the interior of the battery pack. The connection method using an adapter facilitates the disassembly of the connector panel 20 and the MSD panel 30 without affecting the normal operation of the battery pack.

[0029] Combine Figures 1 to 4 As shown, the battery pack of this embodiment, which is easy to install and disassemble, includes a battery box cover 10, a connector panel 20, an MSD panel 30 and a BMU panel 40. The connector panel 20, the MSD panel 30 and the BMU panel 40 of this embodiment are located on the same side of the battery box cover 10. The battery pack body is installed in the battery box cover 10, and the connector panel 20, the MSD panel 30 and the BMU panel 40 are respectively connected to the battery pack body.

[0030] In this embodiment, the connector panel 20 is installed on the side surface of the battery box cover 10, and the positive connector 21 and the negative connector 22 are provided on the connector panel 20. The negative connector 22 is connected to the battery pack body through the first adapter 50. The MSD panel 30 is installed on the side surface of the battery box cover 10, and the MSD switch 31 is provided on the MSD panel 30. The MSD switch 31 is connected to the battery pack body through the second adapter 60. In this embodiment, the connector panel 20 and the MSD panel 30 are arranged on the same side, and the negative connector on the connector panel 20 is connected to the battery pack body. The plug-in 22 is connected to the battery pack body through the first adapter 50, and the MSD switch 31 on the MSD panel 30 is connected to the battery pack body through the second adapter 60. The first adapter 50 and the second adapter 60 of this embodiment are both adapter copper bars. The adapter copper bars are used as the first adapter 50 and the second adapter 60 to realize the adapter processing of the docking plug-in panel 20 and the MSD panel 30, which is beneficial to the subsequent disassembly and assembly of the plug-in panel 20 and the MSD panel 30, thereby facilitating the maintenance of the battery pack body in the battery box cover 10.

[0031] Specifically, the adapter end of the first adapter 50 and the adapter end of the second adapter 60 of this embodiment are both provided with insulating pillars 90 to achieve insulated installation of the connector panel 20 and the MSD panel 30 .

[0032] Combine Figure 1 and Figure 2 As shown, the BMU panel 40 is mounted on the side surface of the battery box cover 10 by screws and is connected to the battery pack body. A communication connector 41 is provided on the BMU panel 40, and the battery pack body is connected to the external communication through the communication connector 41 to meet the communication requirements of the battery pack body.

[0033] In this embodiment, the battery box cover 10 is a sheet metal box cover, and an explosion relief valve 70 is provided on the side of the battery box cover 10. A plurality of lifting holes 11 are provided at the bottom of the battery box cover 10 to facilitate lifting the battery pack body. When excessive pressure occurs in the battery box cover 10, the explosion relief valve 70 can relieve pressure to avoid explosion of the battery pack body. The lifting holes 11 at the bottom of the battery box cover 10 are conducive to lifting the battery during transportation.

[0034] Furthermore, a number of height limit blocks 80 are provided on the side of the battery box cover 10. The height limit blocks 80 are evenly distributed on the side of the battery box cover 10. The presence of the height limit blocks 80, which are provided on the side of the battery box cover 10, can cushion the battery pack and prevent the battery pack from jumping up and down during transportation, which is conducive to the stable transportation of the battery pack.

[0035] In actual use, the battery pack of this embodiment is easy to install and disassemble. The connector panel 20 is connected to the battery pack body through the first adapter 50, and the MSD panel 30 is connected to the battery pack body through the second adapter 60. When the battery pack body inside the battery box cover 10 fails, the connector panel 20 and the MSD panel 30 can be quickly removed to facilitate maintenance of the battery pack body, thereby improving the maintenance efficiency of the battery pack body and reducing maintenance costs. The height limit block 80 installed at the bottom of the battery box cover 10 can stably limit the installation of the battery to prevent the battery pack from jumping up and down during transportation, which is conducive to stable transportation of the battery pack.
