Description

Technical Field

[0001] This utility model relates to the field of energy storage systems, specifically to a home energy storage system. Background Technology

[0002] Home energy storage systems are receiving increasing attention as a key technology for achieving energy self-sufficiency, improving energy efficiency, and enhancing grid stability. Among these, stacked energy storage systems, a significant form of home energy storage, are widely used in homes, small businesses, and remote areas for power supply and storage due to their modular design, ease of expansion, and flexible configuration. This technology encompasses not only core technologies such as battery management, energy conversion, and control, but also system integration, safety protection, and user experience, aiming to provide users with efficient, reliable, and safe energy storage solutions.

[0003] Home energy storage systems typically consist of multiple energy storage units (such as battery modules), a battery management system (BMS), an energy conversion system (such as an inverter), and necessary monitoring and communication components. During operation, stacked energy storage systems form compact and efficient energy storage arrays by vertically or horizontally stacking multiple energy storage units. This allows for flexible adjustment of energy storage capacity according to actual needs, meeting energy storage requirements in different scenarios.

[0004] However, existing home energy storage systems still have some problems that urgently need to be solved. The stacked structure design of existing stacked energy storage systems is relatively simple, mostly relying on direct placement or simple interlocking structures, lacking effective heat dissipation channel design. While this tight stacking method helps reduce space occupation, it also leads to poor air circulation inside the energy storage system, resulting in excessively high local temperatures, which in turn affects battery performance and lifespan, and may even cause safety hazards. In addition, high-temperature environments can accelerate battery aging, reduce overall system efficiency, and increase maintenance costs. Therefore, how to optimize the stacked structure of stacked energy storage systems and improve their ventilation and heat dissipation performance has become an important direction for the development of current home energy storage technology. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned deficiencies and provide a home energy storage system that solves the technical problem that the existing stacked energy storage system has a simple stacked connection structure, which leads to poor air circulation in the stacked area, affects the local temperature, and is therefore not conducive to stable and reliable use.

[0006] The objective of this utility model is achieved through the following means:

[0007] A home energy storage system includes a base, an energy storage module and an energy storage inverter module mounted on the base. The energy storage module consists of multiple energy storage boxes, which are vertically stacked on the base. Each energy storage box includes a box body, an energy storage battery assembly disposed within the box body, and an end cap. The box body has an internal cavity for housing the energy storage battery assembly. A bottom cap is connected to the bottom of the box body, and a support column is connected to the bottom of the bottom cap, allowing two stacked energy storage boxes to form a spaced ventilation space through the support column. A heat dissipation section extends from the bottom of the box body, contacting the top of a stack of energy storage boxes. The heat dissipation section has heat dissipation holes communicating with the ventilation space. A heat dissipation drive component is connected to the bottom of the bottom cap. A wiring section is provided on the side of the box body, and the end cap is mounted on the side of the box body. The energy storage inverter module is mounted on the top of the energy storage box.

[0008] Furthermore, as described above, the inner wall of the housing has a connecting portion for installing the bottom cover. The bottom cover is built into the receiving cavity and connected to the connecting portion via a connector. The end cover is installed on the wiring portion of the housing, and the energy storage battery assembly is connected to an interface that is exposed through the end cover.

[0009] The inner wall of the box is equipped with a connecting part for installing the bottom cover, and the end cover is installed on the wiring part, with the energy storage battery module interface exposed through the end cover. This structure makes the internal structure of the energy storage box reasonable, which is convenient for installation and maintenance. It also ensures the convenience of connecting the energy storage battery module with other components, which helps the stable operation of the entire home energy storage system and indirectly provides a good foundation for solving problems such as poor air circulation in the stacked area.

[0010] Furthermore, as described above, the two adjacent boxes are detachably connected by a connecting frame.

[0011] The two adjacent boxes can be detachably connected by a connecting frame, which facilitates the assembly, disassembly and maintenance of the energy storage system. When a storage box fails, it can be quickly disassembled for repair or replacement, which improves the maintainability of the system. It also facilitates the optimization of the stacked structure of the stacked energy storage system and helps to better solve technical problems such as poor air circulation in the stacked area.

[0012] Furthermore, as described above, the end cap is provided with several through holes and mounting holes for connecting with the connecting bracket.

[0013] The through holes on the end caps facilitate airflow between the inside of the enclosure and the outside, further improving ventilation and heat dissipation. The mounting holes for connecting the end caps to the connecting frame facilitate the connection between the end caps and the connecting frame, ensuring the stability of the entire energy storage system structure. This also helps to solve the problem of poor airflow in the stacked areas, which is conducive to the stable and reliable use of the energy storage system.

[0014] Furthermore, as described above, the bottom of the bottom cover has a ventilation hole that communicates with the ventilation space. The heat dissipation drive is built into the ventilation space. Driven by the heat dissipation drive, the air in the ventilation space can be circulated outward through the heat dissipation hole to form a heat dissipation air duct.

[0015] The bottom cover has ventilation holes that connect to the ventilation space. The heat dissipation drive component is built into the ventilation space to drive the air circulation and form a heat dissipation channel, which greatly enhances the ventilation and heat dissipation effect. It effectively solves the problems of poor air circulation and excessive local temperature in the stacked areas of existing stacked energy storage systems, ensures the stable operation of the energy storage system, improves the performance and life of the battery, and reduces safety hazards and maintenance costs.

[0016] Furthermore, as described above, handles are embedded in both opposite sides of the box.

[0017] The container has built-in handles on both sides, which facilitates the handling and installation of the energy storage box.

[0018] Furthermore, as described above, each of the four corners of the base is connected to a rotatable caster wheel, and a limiter is connected to the upper part of the caster wheel.

[0019] The base is connected to four rotatable casters, which facilitates the movement of the entire home energy storage system and allows the system to be flexibly repositioned according to actual needs.

[0020] The beneficial effects of this utility model are as follows: By setting support columns at the bottom of the bottom cover of the energy storage box, a ventilation space is formed between the stacked energy storage boxes, avoiding the problem of direct and tight contact between the boxes in the traditional stacking method. This significantly improves the air circulation in the stacked area. The heat dissipation part formed by the extension of the bottom of the box contacts the top of the upper energy storage box, and the heat dissipation part has heat dissipation holes that communicate with the ventilation space. This allows heat to be quickly transferred to the ventilation space through the heat dissipation holes and carried away by air convection. The setting of the bottom cover connecting the heat dissipation drive component further enhances the ventilation and heat dissipation effect, thereby reducing the local temperature at the stacking contact. This is conducive to the stable and reliable use of the energy storage system and avoids the situation where the battery performance and life are affected by excessive temperature and the safety hazards are caused.
