Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, specifically to a high-voltage control box. Background Technology

[0002] In energy storage systems, the high-voltage control box is a core component, used to implement functions such as charging and discharging control, protection, and monitoring. Existing energy storage systems typically have at least one battery cluster, and a single high-voltage control box is usually responsible for the charging and discharging control, protection, and monitoring of only one battery cluster. Therefore, when multiple battery clusters are connected in parallel, a corresponding number of high-voltage control boxes are required, leading to higher system costs.

[0003] To solve the above-mentioned technical problems, Chinese utility model patent CN221428637U discloses a high-voltage control box, the structure of which is as follows: Figure 1 As shown, by setting the first control circuit 1a and the second control circuit 2a in the same enclosure 3a, one high-voltage control box can control two battery clusters, thereby reducing the number of high-voltage control boxes in the energy storage system and lowering the cost.

[0004] However, existing high-voltage control boxes still have the following technical problems: Each control loop includes a main positive circuit, a main negative circuit, and a pre-charging circuit. The main positive circuit has a main positive contactor, the main negative circuit has a main negative contactor, and the pre-charging circuit has a pre-charging contactor, resulting in a large number of components, high cost, and cumbersome installation. Current integrated switch solutions, such as the high-voltage control box disclosed in Chinese invention patent application CN119010248A, replace multiple components like the main positive contactor, main negative contactor, and pre-charging contactor with a single integrated switch, significantly reducing the number of components. However, this solution only involves the circuit principle design of the high-voltage control box and does not address the internal structure design, let alone the application of the integrated switch to a high-voltage control box with two control loops. Therefore, it is necessary to design a solution that applies the integrated switch to a high-voltage control box with two control loops, making the internal structure of the high-voltage control box simple, compact, and easy to install. Summary of the Invention

[0006] The technical solution of this utility model is: a high-voltage control box, including a box body, a first control circuit is arranged on the left side and a second control circuit is arranged on the right side of the box body, and a first battery cluster interface area is arranged on the left side and a second battery cluster interface area is arranged on the right side of the bottom of the box body; the first control circuit includes a first fusion switch, and a first fuse and a first pre-charge resistor arranged above the first fusion switch; the second control circuit includes a second fusion switch, and a second fuse and a second pre-charge resistor arranged above the second fusion switch; a first mounting base fixed to the box body is provided on the rear side of the first fusion switch, and a first pre-positioning structure is provided between the bottom of the first fusion switch and the bottom of the box body; a second mounting base fixed to the box body is provided on the rear side of the second fusion switch, and a second pre-positioning structure is provided between the bottom of the second fusion switch and the bottom of the box body.
