Description

Technical Field

[0001] The present invention relates to the technical field of energy storage containers, and in particular to an integrated energy storage high-voltage box layout structure. Background Art

[0002] The high-voltage box is a management unit for battery packs or battery clusters. It improves the charge and discharge control for battery packs or battery clusters, provides power-on control for external high-voltage components, and is responsible for collecting the voltage, current, temperature and other information of the batteries in the battery packs or battery clusters and uploading them in a package. It realizes functions such as battery overload and short circuit protection, high-voltage sampling, and low-voltage control, and protects and monitors the operation of the high-voltage system. The high-voltage box is an indispensable device in the energy storage container system. The number of configurations has an important impact on the size, cost and maintenance convenience of the energy storage container. Therefore, the development of an integrated high-voltage box has significant necessity and practical application value.

[0003] At present, in the design of energy storage containers, the number of high-voltage boxes is usually customized according to project requirements. For example, one high-voltage box is configured for each battery cluster, and the number and cost of high-voltage boxes are relatively high; two high-voltage boxes are configured for a single-row two-cluster battery cluster, which increases the height of the container, thereby increasing the cost. In addition, the high-voltage box is relatively short relative to the battery PACK. When arranged vertically, the space behind the high-voltage box in the width direction of the container is greatly wasted. Therefore, the current design of energy storage containers leads to problems such as low space utilization, high cost, and complex installation. Especially in large-scale energy storage projects, too many or too few high-voltage boxes may cause low system efficiency or safety hazards. Therefore, how to optimize the layout structure of integrated energy storage high-voltage boxes has become a technical problem that needs to be solved urgently in this field. Summary of the invention

[0004] The purpose of the present invention is to provide an integrated energy storage high-voltage box layout structure, which improves space utilization through integrated design, effectively reduces the number of high-voltage boxes, and further reduces the structural cost of the high-voltage boxes, thereby reducing the cost of the energy storage container system, while ensuring the safety and reliability of the energy storage system operation.

[0048] Specifically, the layout structure of the integrated energy storage high-voltage box is introduced as follows:

[0056] There are four power terminals 31, and the positive power flow and the negative power flow correspond to two power terminals 31 respectively; the power terminals of the positive power flow and the negative power flow are respectively used to connect the positive power terminal and the negative power terminal of the corresponding output of the external battery cluster;

[0057] The connection structure between the copper busbar assembly and the power device assembly in the positive power flow is:

[0058] One of the power terminals 31, the fuse 35, the main positive reactor 36, the main positive contactor 34, and the main circuit breaker 32 are electrically connected in sequence through a copper busbar, and the main circuit breaker 32 is electrically connected to another power terminal 31 through a copper busbar;

[0059] The connection structure between the copper busbar assembly and the power device assembly in the negative power flow is:

[0060] One of the power terminals 31 is electrically connected to the cluster current sampling module 33 through a copper busbar. The cluster current sampling module 33, the main negative inductor 37, the main negative contactor 38, and the main circuit breaker 32 are electrically connected in sequence through the copper busbar. The main circuit breaker 32 is electrically connected to another power terminal 31 through the copper busbar.

[0061] A shunt is also provided between the main circuit breaker 32 and the cluster current sampling module 33, and the two ends of the shunt are respectively connected to the main circuit breaker 32 and the cluster current sampling module 33 through copper bars. The shunt is used to measure direct current and has the functions of shunting current, controlling the direction of current flow, and distributing the proportion of current.

[0062] Specifically, the power device assembly on one side close to the bottom plate 14 of the box is a first power device assembly, and the position layout of the first power device assembly is as follows: the power terminal 31 is arranged on the front panel 15 of the box; the fuse 35 is located behind the power terminal 31 and is arranged close to the bottom plate 14 of the box; the main positive contactor 34 is located on the left side of the fuse 35, the main positive reactor 36 is arranged behind the main positive contactor 34 and the fuse 35, the main circuit breaker 32 is arranged in front of the main positive contactor 34, the cluster current sampling module 33 is arranged between the main circuit breaker 32 and the main positive contactor 34, and the main negative contactor 38 is arranged on the left side of the main positive contactor 34; the main negative reactor 37 is located behind the main negative contactor 38 and is located to the left rear of the main positive reactor 36;

[0064] exist Figure 1In the layout installation state shown, two groups of copper busbar assemblies 2 and two groups of power device assemblies 3 are symmetrically arranged along the center line of the box width direction, corresponding to two battery clusters, to achieve power flow control of the two battery clusters.

[0065] The main functions of the power device assembly 3 are: suppressing harmonics, controlling and protecting, and performing voltage and current sampling.

[0076] The present invention mainly adopts an integrated energy storage high-voltage box layout structure. Compared with the traditional energy storage container that has two high-voltage boxes for a single row of two battery clusters (or one high-voltage box for a single row of a single battery cluster), the present invention adopts an integrated high-voltage box, and one integrated high-voltage box is configured for each single row of two battery clusters (or two rows of two clusters). This can effectively reduce the number of high-voltage boxes configured, further reduce the structural cost of the high-voltage box, and thus reduce the cost of the energy storage container.
