Description

Technical Field

[0001] The utility model relates to the technical field of energy storage battery packs, and more specifically, to an energy storage battery pack with separate compartments for battery cells and a BMS. Background Art

[0002] With the widespread adoption of renewable energy and electric vehicles, demand for energy storage battery packs is increasing. As a core component of energy storage battery packs, the battery management system (BMS) is primarily responsible for monitoring and managing battery charge and discharge status, temperature, voltage, and other parameters. However, during the design and manufacturing process of existing energy storage battery packs, the battery cells and the BMS are often located in the same compartment. A malfunction or fire in the BMS can easily damage the battery cells and even cause widespread fires, posing a serious threat to personal and property safety. Therefore, it is necessary to develop an energy storage battery pack that separates the battery cells and the BMS. Utility Model Content

[0003] The purpose of the utility model is to provide an energy storage battery pack with separate compartments for battery cells and BMS, so as to improve the safety and service life of the battery pack.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A battery storage battery pack with separate compartments for battery cells and BMS includes a box, a sheet metal part and a cover plate. The upper end of the box is provided with a cell cavity for accommodating battery cells, and the lower end of the box is provided with a BMS cavity for accommodating a BMS battery management system. A sheet metal part is provided between the cell cavity and the BMS cavity, and the cover plate is detachably provided on the box outside the cell cavity.

[0006] Furthermore, the cover plate is made of epoxy resin board.

[0007] Compared with the existing technology, the advantages of the present invention are: the present invention stores the BMS battery management system and the battery cells completely independently. When the BMS fails and catches fire, the battery cells will not be burned, avoiding large-scale fires and reducing personal and property risks. The heat of the BMS will not affect the battery cells, which is conducive to maintaining the battery cells in good working condition and extending their service life. At the same time, the box is made of sheet metal parts and epoxy resin boards, with a compartment design, simple structure, and easy to manufacture and maintain. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0014] See Figure 1-3 As shown, the utility model provides an energy storage battery pack with separate compartments for battery cells and BMS, including a box body 3, a sheet metal part 4 and a cover plate 5. The upper end of the box body 3 is provided with a battery cell cavity for accommodating the battery cell 1, and the lower end of the box body is provided with a BMS cavity for accommodating the BMS battery management system 2. A sheet metal part 4 is provided between the battery cell cavity and the BMS cavity, and the cover plate 5 is detachably provided on the box body 3 outside the battery cell cavity.

[0015] In this embodiment, the cover plate 5 is made of epoxy resin board.

[0016] The utility model divides the box into two completely independent upper and lower storages through sheet metal parts, which are used to place battery cells 1 and BMS battery management system 2 respectively. When the BMS fails and catches fire, the battery cells will not be burned, avoiding large-scale fire and reducing personal and property risks. Moreover, during use, the heat of the BMS will not affect the battery cells, which is conducive to maintaining the battery cells in good working condition and extending their service life. At the same time, the box is made of sheet metal parts and epoxy resin boards, with a compartment design, a simple structure, and is easy to manufacture and maintain.
