[0031] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] Reference below Figure 1 and Figure 2 A CTR container 100 according to an embodiment of the present invention is described.

[0033] like Figure 1 As shown, a CTR container 100 according to an embodiment of the present invention includes: a battery cluster 1 and a box body 2 .

[0034] Specifically, the battery cluster 1 includes a base 11 and multiple battery cells 12, which are stacked on the base 11. The base 11 includes first crossbeams 111, with first longitudinal beams 112 connecting the first crossbeams 111. The container 2 defines a receiving cavity, within which the battery cluster 1 is located. The container 2 includes multiple second crossbeams 21, which are spaced apart along the length of the container 2. The first crossbeams 111 and the second crossbeams 21 are vertically connected. As a result, the CTR container 100 has an ingenious structural design and low production costs.

[0035] According to the CTR container 100 of the embodiment of the present invention, through the integrated design of the box body 2 and the battery cluster 1, multiple battery cells 12 are directly stacked to form the battery cluster 1. The length of the battery cluster 1 and the width of the container are fully utilized to achieve direct connection between the base 11 of the battery cluster 1 and the box body 2. This improves the overall bending strength of the CTR container 100, reduces the number of structural components of the CTR container 100, reduces production costs, reduces the welding workload of the CTR container 100, reduces stress and deformation caused by welding, and improves the production efficiency of the CTR container 100.

[0036] In some embodiments of the present invention, the first crossbeam 111 and the second crossbeam 21 are fixedly connected by a mortise and tenon structure, thereby eliminating the need for additional fasteners such as nails or screws, and providing a stable and durable connection.

[0037] In some embodiments of the present invention, a first fixing hole 1121 is formed on the first longitudinal beam 112, and the box body 2 includes a second longitudinal beam 22, and a second fixing hole is formed on the second longitudinal beam 22. The base 11 and the box body 2 are fixedly connected by fasteners passing through the first fixing hole 1121 and the second fixing hole, ensuring that a solid whole is formed between the base 11 and the box body 2. This not only provides sufficient strength to support the battery cluster 1 and its weight, but also facilitates disassembly and maintenance, thereby ensuring the stability and safety of the CTR container 100. A shipping port 1122 is formed on the first longitudinal beam 112 for accommodating the tines of a forklift, thereby improving its convenience during actual transportation and loading and unloading and increasing its flexibility of use.

[0038] In some embodiments of the present invention, as shown in the figure, a limiting plate 13 is provided on the top of the battery cluster 1. Along its length, the width of the limiting plate 13 gradually decreases from the center toward the ends. This provides guidance for the battery cluster 1 as it enters the container and helps shape the battery cluster 1. It also prevents tipping and provides a fixed position, thereby improving the overall stability of the CTR container 100.

[0039] In some embodiments of the present invention, as shown in the figure, multiple battery clusters 1 are arranged along the width of the battery cluster 1. Each battery cluster 1 includes multiple cold plates, end plates, electrical components, a battery management unit (BMU), and liquid cooling pipes. The electrical components, BMU, and liquid cooling pipes are all located on the same side of the battery cluster 1. This facilitates maintenance and ensures efficient operation and long-term reliability of the battery clusters 1 in the CTR container 100.

[0040] Furthermore, as shown in the figure, a connecting piece 3 is provided between each two adjacent battery clusters 1, and the connecting piece 3 is located on the upper part of the battery cluster 1. This not only enhances the stability and safety of the battery cluster 1, but also improves the overall bending strength of the container.

[0041] In some embodiments of the present invention, a control combiner cabinet 4 is provided at one end of the storage chamber, and a PDU 5 is provided at the other end. Multiple PDUs 5 are provided, each corresponding to a plurality of battery clusters 1. This enables independent monitoring and management of each battery cluster 1, improving the flexibility and reliability of the CTR container 100. Furthermore, problematic battery clusters 1 can be quickly located and isolated using the corresponding PDU 5 without affecting the normal operation of other battery clusters 1. This not only provides an efficient and reliable power management and distribution mechanism, but also enhances the maintainability and scalability of the CTR container 100. The control combiner cabinet 4 and PDU 5 together form a powerful power management system, ensuring the stable operation and long-term performance of the CTR container 100.

[0042] In some embodiments of the present invention, the CTR container 100 further includes a fire protection system 6, which includes a smoke sensor, a temperature sensor, a combustible and hazardous gas detector, and a fire extinguisher. The fire extinguisher is located at the other end of the storage chamber and spaced apart from the PDU 5. Thus, the fire extinguisher is located at one end of the storage chamber, away from the PDU 5 and other electrical equipment. This reduces the impact of the fire extinguishing agent on the electrical equipment while ensuring that the fire extinguishing agent effectively covers the entire storage chamber.

[0043] Furthermore, the lower part of the fire fighting tank is a water inlet pipe of the fire fighting pipe, and the fire fighting riser extends from the corner to the top and is connected with the nozzle pipe.

[0044] In some embodiments of the present invention, the CTR container 100 further includes a water generator 7, which is located outside the receiving cavity and at one end of the container 2. Placing the water generator 7 outside the receiving cavity effectively utilizes the space outside the container 2, avoiding occupying the internal space of the container 2. The location of the water generator 7 at one end of the container 2 facilitates connection to the internal cooling pipes and facilitates maintenance and repair. The water generator 7 maintains a certain distance from the PDU 5 and other electrical equipment, reducing potential electrical interference and safety risks.

[0045] In some embodiments of the present invention, the storage chamber includes a first chamber 24 and a second chamber 25 arranged at intervals. Multiple battery clusters 1 are located in the first chamber 24, and the control combiner cabinet 4 and PDU 5 are both located in the second chamber 25. It is understood that separating the battery clusters 1 from the control and power distribution equipment can reduce the risk of electrical failure or fire spreading. Technicians can perform maintenance and repairs on the control combiner cabinet 4 and PDU 5 without disturbing the battery clusters 1. The heat generated by the battery clusters 1 will not directly affect sensitive electronic equipment, thereby improving the stability and reliability of the overall system and facilitating expansion and upgrades, such as adding more battery clusters 1 or replacing control equipment. Through reasonable space division, the space inside the container can be more efficiently utilized.

[0046] Furthermore, the busbar cables, liquid cooling main pipelines and fire protection pipelines of the battery cluster 1 are designed to be arranged at the top of the first cavity 24, maintaining the concealed design of the energy storage cables and pipelines of the CTR container 100, improving the visual effect of the product and reducing interference between lines and pipelines during maintenance.

[0047] Preferably, the base 11 of the battery cluster 1 is a steel frame structure.

[0048] In some embodiments, a slide rail 23 is formed on one of the bottom of the box body 2 and the base 11, and a slide groove 14 is formed on the other of the bottom of the box body 2 and the base 11. The box body 2 and the base 11 slide relative to each other through the slide rail 23 and the slide groove 14. This reduces the difficulty of assembling the CTR container 100 and improves production efficiency.
