[0040] As described in the background of this application, a battery energy storage system includes multiple energy storage battery packs (PACKs). The battery management unit (BMU) is a key component of the energy storage battery pack, used to monitor and manage the energy storage battery system. With the rapid development of the energy storage industry in recent years, the structure of energy storage battery packs has become increasingly integrated to efficiently utilize the space inside the container.

[0041] The inventors of this application have discovered that the battery management units of most current energy storage battery packs are often placed on the back of the cover installed on the battery pack shell, which not only brings great inconvenience to the installation and debugging of a single battery management unit, but also requires the cover to be disassembled before the entire battery pack can be disassembled. The installation and maintenance procedures of the battery pack are cumbersome and complicated. Moreover, the cover is made of metal material, and the electrical safety distance needs to be controlled, which reduces space utilization.

[0042] In order to solve the above problems, the author of the present application has proposed the technical solution of the present application, and the specific embodiments are as follows:

[0044] like Figures 1 to 4 As shown, the front panel of the integrated energy storage battery pack of this embodiment includes: a mounting plate 1 , a main cover plate 2 , a left cover plate 31 and a right cover plate 32 .

[0045] The mounting plate 1, main cover 2, left cover 31, and right cover 32 are all made of flame-retardant, insulating plastic and are integrally molded via injection molding. This allows the front panel to provide live electrical protection, resulting in more efficient space utilization compared to metal front panels that require strict electrical safety distance management. Injection molding plastic materials include, but are not limited to, PA66, PC+ABS, and ABS.

[0046] A square opening is provided in the middle of the mounting plate 1 .
