[0021] The present application is provided with the following description with reference to the accompanying drawings to help fully understand various embodiments of the present application as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as merely exemplary. Therefore, those skilled in the art will recognize various changes and modifications to the various embodiments described herein without departing from the scope and spirit of the present application.

[0022] In the description of the utility model, the orientation description, such as the orientation or positional relation of the indication of up, down, front, back, left, right etc. for the orientation or positional relation shown in the drawing, is only for the convenience of describing the utility model and simplifying the description, and is not to indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, and therefore can not be understood as limiting the utility model.

[0023] It should be understood that when an element (e.g., a first element) is "connected" with another element (e.g., a second element), the element can be directly connected with the other element, or there can be intervening elements (e.g., a third element) between the element and the other element.

[0024] The embodiment of the utility model provides a kind of stacked energy storage system, as shown in Figures 1-4 Including:

[0025] One or more battery modules 100 are sequentially stacked.

[0026] The host computer 200 is detachably connected with the battery module 100, and the host computer 200 is used for energy management and control. The host computer 200 includes an outer shell 210 with an upper opening and a heat sink 220. The heat sink 220 is detachably fixed at the upper opening of the outer shell 210 and covers the upper opening of the outer shell 210. The height of one side wall of the outer shell 210 is greater than that of the other side wall, and the heat sink 220 is placed obliquely.

[0027] The battery module 100 can be one or more, and is sequentially stacked. This stacking method is beneficial to save space, so that the entire energy storage system is more compact, and is convenient to install and arrange in different places, such as indoor machine room, outdoor, etc. For example, a plurality of battery modules 100 are stacked together to form a battery pack with a certain height and volume.

[0028] The host computer 200 is detachably connected with the battery module 100, and its main function is to manage and control energy. The host computer 200 can manage the charging and discharging of the battery module 100, such as controlling the charging current and voltage, preventing overcharging and overdischarging, to protect the performance of the battery module 100 and prolong its service life. At the same time, it can also distribute and dispatch the energy in the energy storage system, reasonably control the charging and discharging power of the battery module 100 according to different load requirements or grid instructions, and realize the effective use of energy.

[0029] The upper end of the shell 210 of the host 200 is open, which facilitates the installation, maintenance and heat dissipation of the internal components. The upper end opening can conveniently place some heat dissipation components or components that need to be cooled at the opening, facilitating heat dissipation. The heat dissipation fins 220 are detachably connected to the upper end of the shell 210. The detachable design makes it more convenient to clean, replace or maintain the heat dissipation fins 220 when needed, improving the maintainability of the system. The heat dissipation fins 220 function to dissipate the heat generated inside the host 200, so as to ensure that the host 200 operates within the normal operating temperature range and prevents faults or performance degradation caused by overheating.

[0030] The height of one side wall of the shell 210 is greater than that of the other side wall, which is a structural design to place the heat dissipation fins 220 obliquely. The obliquely placed heat dissipation fins 220 allow rainwater to flow along the oblique direction of the heat dissipation fins 220 in rainy weather, preventing water from remaining on the surface of the energy storage system for a long time. Moreover, the inclined heat dissipation fins 220 can increase the contact area with air, promote air flow, and thus improve the heat dissipation efficiency. For example, when air flows from the lower side to the higher side of the heat dissipation fins 220, it can better carry away heat. The obliquely placed heat dissipation fins 220 and the detachable heat dissipation fins 220 design can effectively improve the heat dissipation effect, ensure that the host 200 and the battery module 100 operate within the normal temperature range, and improve the reliability and service life of the system. The detachable connection of the host 200 and the battery module 100 and the detachable design of the heat dissipation fins 220 make the maintenance of the system more convenient, reducing the maintenance cost and time.

[0031] In some embodiments, a plurality of water guide grooves parallel to the oblique direction of the heat dissipation fins 220 are arranged on the heat dissipation fins 220.

[0032] The water guide grooves can be independently arranged on the heat dissipation fins 220 or formed by heat conduction fins on the heat dissipation fins 220. The water guide grooves can accelerate the flow of rainwater and improve the water guide efficiency.

[0033] In some embodiments, the upper end of the shell 210 is provided with a mounting portion 211 for fixing the heat dissipation fins 220.

[0034] By setting the mounting portion 211 at the upper end, the heat sink 220 can be firmly fixed on the shell 210, avoiding loosening or displacement of the heat sink 220 due to vibration, external force impact or long-time operation. The design of the mounting portion 211 can make the contact between the heat sink 220 and the shell 210 more closely, thereby improving the heat dissipation efficiency. Good contact between the heat sink 220 and the shell 210 can better conduct heat, allowing the heat inside the shell 210 to be quickly transferred to the heat sink 220, and then dissipated through air flow. The design of the mounting portion 211 makes the installation and removal of the heat sink 220 more convenient. Maintenance personnel can easily install the heat sink 220 on the shell 210, or quickly remove it when cleaning or replacing the heat sink 220, thereby reducing maintenance cost and time. The detachable connection of the mounting portion 211 can adopt, for example, threaded connection, buckle connection or magnetic attraction connection, etc. These connection methods not only ensure the stability of the heat sink 220, but also facilitate maintenance and replacement.

[0035] In some embodiments, the mounting portion 211 can also be designed to allow the heat sink 220 to adjust the inclination angle within a certain range. This design can flexibly adjust the angle of the heat sink 220 according to different heat dissipation needs and space layout, further optimizing the heat dissipation effect. For example, by adjusting the angle of the heat sink 220, it can better adapt to the direction of air flow, thereby improving the heat dissipation efficiency.

[0036] Further, the mounting portion 211 is annular, and the outer wall of the mounting portion 211 abuts against the inner wall of the shell 210.

[0037] The annular mounting portion 211 can uniformly fix the heat sink 220 on the shell 210, avoiding deformation or loosening of the heat sink 220 due to uneven local stress. This uniform fixing method can ensure that the heat sink 220 remains stable during operation, and can maintain good heat dissipation effect even under vibration or external force impact. The design of the annular mounting portion 211 is relatively simple and easy to process and manufacture. It can be realized by common processes such as injection molding, stamping or machining, reducing production cost. At the same time, the annular structure is also more convenient to install and maintain, and maintenance personnel can quickly install the heat sink 220 in place, improving maintenance efficiency.

[0038] In some embodiments, the annular mounting portion 211 can be designed to have certain adjustability. For example, by setting threads or clamping grooves on the mounting portion 211, the installation position and inclination angle of the heat sink 220 can be adjusted. This adjustability can flexibly adjust the angle of the heat sink 220 according to different heat dissipation needs and space layout, further optimizing the heat dissipation effect.

[0039] In some embodiments, the mounting portion 211 and the shell 210 are integrally formed.

[0040] The mounting portion 211 is integrally formed with the housing 210, eliminating the connection gap, avoiding the problem of unstable fixing of the heat sink 220 due to loose or broken connection. This design can significantly improve the structural strength of the entire system, ensuring that the heat sink 220 remains stable during operation, even under vibration or external force impact. The integrally formed design can reduce the problem of air or moisture infiltration due to poor sealing at the connection. In outdoor or humid environments, good sealing can prevent moisture from entering the interior of the housing 210, protecting internal electronic components from corrosion and short circuit risks. The integrally formed mounting portion 211 and housing 210 can be formed in one step through processes such as injection molding, casting or stamping, reducing assembly steps and the use of connecting components. This not only reduces production costs, but also improves production efficiency, while reducing quality problems caused by assembly errors.

[0041] In some embodiments, a sealing ring is also connected between the heat sink 220 and the mounting portion 211. The sealing ring can further improve the waterproof performance of the energy storage system.

[0042] In some embodiments, the back of the housing 210 is provided with a first wire slot 212 for wiring, and the first wire slot 212 penetrates the top surface of the housing 210.

[0043] The first wire slot 212 is arranged on the back of the housing 210, which can make full use of the idle space of the housing 210, avoiding excessive impact on the overall layout of the energy storage system. At the same time, the back position is also convenient for the access and maintenance of the wires, without interfering with the normal operation of the system. The size of the first wire slot 212 is designed according to the specifications and number of wires to ensure that the wires can be placed neatly in the slot. For example, if the wires are more or thicker, the depth and width of the wire slot can be increased accordingly to meet the accommodation needs of the wires. By wiring, the risk of damage to the wires by external forces and environmental influences is reduced, thereby improving the reliability of the system. For example, in outdoor environments, the wire slot can prevent rainwater, dust and ultraviolet light from eroding the wires, extending the service life of the wires. Wiring can make the entire energy storage system look more neat and beautiful, especially in some application scenarios with high requirements for aesthetics, such as commercial buildings or data centers, this design can better integrate into the surrounding environment.

[0044] In some embodiments, the first wire slot 212 can be equipped with a detachable cover plate. This design can easily open the cover plate for wire installation, inspection or replacement when needed, while the cover plate can protect the wires from external interference during normal operation. The cover plate can be fixed on the shell 210 by buckle, screw or other detachable connection methods. The design of the first wire slot 212 makes it more convenient for wire installation and maintenance. Maintenance personnel can easily put the wires into the slot and protect them through the detachable cover plate. This design not only improves the maintenance efficiency, but also reduces the maintenance cost.

[0045] Further, the bottom wall of the first wire slot 212 is provided with a terminal slot 213 for setting the terminal.

[0046] By opening the terminal slot 213 on the bottom wall of the first wire slot 212, the terminal can be placed in a fixed position. This design makes the connection of the wire more orderly, avoiding the terminal to be distributed randomly in the wire slot, thereby improving the neatness and aesthetics of the system. The terminal slot 213 can provide a stable installation environment for the terminal, ensuring that the terminal will not loosen or shift during operation. The centralized placement of the terminal makes maintenance and inspection more convenient. Maintenance personnel can quickly locate the position of the terminal for wire connection, inspection or replacement operation. This design not only improves the maintenance efficiency, but also reduces the risk of system failure caused by wiring problems. The terminal slot 213 can be designed with fixed structures such as threaded holes, card slots or protrusions, etc. for fixing the terminal. These fixed structures can ensure that the terminal will not loosen during operation, improving the stability of the connection. For example, by fixing the terminal in the terminal slot 213 with screws, it can effectively prevent the terminal from loosening due to vibration.

[0047] In some embodiments, the terminal slot 213 and the first wire slot 212 can be designed in coordination to ensure that the wire can smoothly enter the terminal slot 213 from the wire slot and be connected with the terminal. This design can reduce the bending and wear of the wire, improving the service life of the wire.

[0048] Further, the lower end of the terminal slot 213 is provided with a slope 214 for guiding the wire out of the wire.

[0049] The slope 214 can guide the wires to smoothly exit the terminal groove 213, reducing the bending and friction of the wires when entering and exiting the terminal groove 213. This design makes the arrangement of wires more smooth, avoiding damage caused by forced bending or pulling of the wires, especially during installation. It can significantly improve the service life of the wires. The design of the slope 214 makes the installation of wires more convenient and efficient. Maintenance personnel can easily guide the wires along the slope 214 into the terminal groove 213 without the need for additional tools or complex operations. This design not only improves installation efficiency, but also reduces installation difficulty. The slope 214 can ensure that the wires maintain a certain angle and direction when entering the terminal groove 213, making the layout of the wires more orderly and neat. This optimized layout not only looks beautiful, but also reduces the mutual interference between the wires, further improving the reliability of the system.

[0050] In some embodiments, the battery module 100 is provided with a second wire slot 110 opposite the first wire slot 212.

[0051] By providing a second wire slot 110 opposite the first wire slot 212 on the battery module 100, seamless connection of wires between the battery module 100 and the host 200 can be achieved. This design makes the transition of wires from the battery module 100 to the host 200 more smooth, avoiding the clutter and exposure of wires at the connection, improving the neatness and aesthetics of the system.
