Description

Technical Field

[0001] The utility model relates to the technical field of energy storage boxes, and in particular to a modular integrated energy storage box. Background Art

[0002] In modern power systems, substations play a key role in converting voltage, receiving, and distributing electricity. With technological innovation and advancements in cost control, substations must not only meet basic power conversion functions but also demonstrate greater flexibility to adapt to dynamically changing power demands. Especially with the growing availability of renewable energy, substations face the challenge of integrating and managing intermittent energy, requiring them to handle this energy more efficiently. Therefore, the application of energy storage boxes has become increasingly important. They not only help balance supply and demand fluctuations in the power grid, but also improve the overall efficiency of the power system and promote the effective use of clean energy. To further enhance rapid deployment capabilities and the ability to respond to changing on-site conditions, the energy storage box adopts a modular, integrated design, which facilitates installation and maintenance, enabling the energy storage system to better match various application scenarios, thereby improving its performance and reliability.

[0003] However, the modular integrated energy storage boxes in the prior art often have the problem of insufficient space at the bottom of the battery pack, resulting in poor air circulation at the bottom of the battery pack. The heat generated during the operation of the battery pack is difficult to be effectively discharged, resulting in local temperature increase, which in turn affects the normal working performance of the battery. In the long run, it will also accelerate the aging process of the battery, shorten the battery service life, and thus reduce the reliability of the energy storage system.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

An electrical control module, an inverter module, a power distribution module and a high-voltage module are sequentially arranged on one side of the plurality of pull-out placement components in a direction away from the top of the box frame.

[0008] Furthermore, in order to increase the heat dissipation space at the bottom of the battery pack and accelerate the heat dissipation efficiency, the heat dissipation space at the bottom of the battery pack can be increased under the action of the conical structure of the heat dissipation convex plate and the heat dissipation concave plate. At the same time, the air can circulate under the action of the mutual penetration of through hole 1 and through hole 2 and the heat dissipation holes, which greatly accelerates the heat dissipation efficiency and improves the service life of the battery pack.
