DETAILED DESCRIPTION

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0024] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0025] It should be understood that the terms "length", "width", "up", "down", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0027] It's important to note that with the rapid development of new energy technologies, mobile energy storage and charging devices, as an emerging technology product, have shown tremendous potential for application in power emergency response, grid peak regulation, and distributed energy storage. However, existing technology still has many deficiencies in the electrical layout, safety escape design, and heat dissipation systems of mobile energy storage and charging devices. In particular, technical improvements and optimizations are urgently needed in terms of fire safety, electric shock protection, and heat dissipation efficiency.

[0028] The electrical layout of existing mobile energy storage and charging systems only provides a single rear door as an escape route. In an emergency, such as a fire breaking out near the rear door, the single escape route, potentially obstructed by the rapid spread of fire, would make escape extremely difficult for personnel inside the vehicle, potentially resulting in irreversible personal injury. Furthermore, the maintenance access is flanked by high-voltage circuits, increasing the risk of electric shock. During maintenance or routine inspections, improper operation or inadequate protective measures can easily lead to electric shock, posing a serious threat to personnel safety. Therefore, it is crucial to rationally layout the high-voltage circuits and implement effective isolation and protective measures to reduce the risk of electric shock. Furthermore, existing systems have flawed heat dissipation channel designs, making the energy storage power supply susceptible to overheating during extended operation, thus impacting its service life and safety. This inappropriate heat dissipation channel design not only increases energy consumption but can also cause safety hazards such as fires. Therefore, it is necessary to optimize the heat dissipation channel structure and improve heat dissipation efficiency to ensure stable and safe operation of the energy storage power supply.

[0029] Therefore, this application improves the relevant mobile emergency energy storage devices and energy storage equipment based on this.

[0030] See also Figure 1 , Figure 1The schematic diagram of the mobile emergency energy storage device provided in this embodiment shows the structure of the mobile emergency energy storage device. The mobile emergency energy storage device in this embodiment includes a container 100 and a battery pack 200. The container 100 has a width direction a and a length direction b. The container 100 has a first side portion and a second side portion spaced apart from each other along the width direction a. The first side portion and / or the second side portion are provided with an opening 110. The battery pack 200 is disposed within the container 100, facing the opening 110 and partially covering the opening 110. A maintenance access 300 is provided on at least one side of the battery pack 200 along the length direction b. The maintenance access 300 extends along the width direction a.

[0031] It should be noted that the container 100 can be configured as a rectangular parallelepiped; the largest left and right sides of the container 100 are designated as the first and second sides. A maintenance door 120 can be provided on the opening 110, which is opened when access to the maintenance passage 300 is required. The battery pack 200 is placed within the container 100 and is specifically designed to face the opening 110. This layout not only facilitates direct external monitoring and maintenance of the battery pack 200, but also helps reduce the space required within the container 100 for maintenance.

[0032] Current energy storage devices often have battery packs 200 arranged along the length direction b. This means that when repairing the innermost battery pack 200, maintenance personnel must enter the device at the maximum depth along the length direction b, making it difficult for them to escape in the event of a fire. However, in the present application, maintenance personnel can enter the maintenance passage 300 along the width direction a of the container 100 and perform maintenance along the maintenance passage 300 arranged along the width direction a. This prevents maintenance personnel from entering the high-voltage electrical system and being unable to escape in time, thereby improving the safety of mobile emergency energy storage devices.

[0033] In some embodiments of this application, please continue to refer to Figure 1 In this embodiment, a first maintenance operation surface 210 is provided on a side of the battery pack 200 near the opening 110. The first maintenance operation surface 210 is exposed in the opening 110. It is understood that maintenance personnel can open the maintenance door 120 and perform maintenance operations on the first maintenance operation surface 210 from the opening 110, which is conducive to improving operability and safety.

[0034] In some embodiments, both the first side and the second side of the container 100 are provided with openings 110 , and correspondingly, both sides of the battery pack 200 close to the first side and the second side are provided with first maintenance operation surfaces 210 .

[0035] In some embodiments of this application, please continue to refer to Figure 1The mobile emergency energy storage device of this embodiment further includes a control device 600, which is connected to the battery pack 200; the control device 600 is spaced apart on one side of the battery pack 200 along the length direction b, and a maintenance channel 300 is formed between the control device 600 and the battery pack 200.

[0036] It should be noted that the independent placement of the control device 600 and the battery pack 200 in this embodiment achieves a modular design. This design clarifies the functions of each component, making it easier to upgrade, replace, or repair them independently without affecting other parts of the system. The maintenance access 300 formed between the control device 600 and the battery pack 200 not only facilitates routine maintenance of the battery pack 200, but also makes the control device 600 itself easily accessible and maintainable. This dual-channel design (if a similar design is also provided on the other side of the battery pack 200) or a single-side expansion design significantly improves the maintainability of the entire system. Furthermore, as the management and monitoring center for the battery pack 200, the stable operation of the control device 600 is crucial to the safety of the entire system. Separating it from the battery pack 200 and isolating it via the maintenance access 300 can, to a certain extent, reduce the risk of damage to the control device 600 caused by a battery pack 200 failure, thereby improving the overall safety of the system.

[0037] In some embodiments of this application, please continue to refer to Figure 1 Also see Figure 2 , Figure 2 A second maintenance operation table 610 is provided on the side of the control device 600 close to the maintenance passage 300 in this embodiment. The second maintenance operation table 610 is exposed in the maintenance passage 300 .

[0038] It should be noted that the second maintenance operation table 610 provides maintenance personnel with a dedicated platform for maintaining, inspecting, or debugging the control device 600. Because the table is directly exposed to the maintenance passage 300, maintenance personnel can easily reach the operating position without additional tools or equipment. This not only greatly shortens maintenance time and improves work efficiency, but also optimizes the internal space of the container 100.

[0039] In some embodiments of this application, please continue to refer to Figure 2 Also see Figure 3 , Figure 3 A cooling fan 700 is provided at one end of the container 100 near the control device 600. One side of the cooling fan 700 is connected to the interior of the container 100, and the other side is connected to the outside of the container 100.

[0040] It should be noted that the cooling fan 700 can directly extract the hot air inside the box and discharge it outside the box, while simultaneously drawing in cool, fresh air from outside the box. This continuous air flow effectively reduces the temperature around the control device 600 and battery pack 200, preventing device performance degradation or failure due to high temperatures.

[0041] In some embodiments, an automatic shutter 710 is provided on the side of the cooling fan 700 close to the outside of the box. The automatic shutter 710 is opened when the cooling fan 700 needs to be started, and is closed when the cooling fan 700 needs to be turned off.

[0042] In some embodiments of this application, please continue to refer to Figure 1 The mobile emergency energy storage device of this embodiment also includes a thermal management device 400, which is used to cool or heat the battery pack 200; the thermal management device 400 is spaced apart on a side of the battery pack 200 away from the control device 600, and a maintenance channel 300 is defined between the thermal management device 400 and the battery pack 200.

[0043] It should be explained that the thermal management device 400 may include a cooling device and a heating device, and the cooling device is used to cool the battery pack 200, and the heating device is used to heat the battery pack 200, so as to limit the battery pack 200 to a suitable temperature range.

[0044] In some embodiments of this application, please continue to refer to Figure 1 The mobile emergency energy storage device of this embodiment also includes a firefighting device 500, which is used to extinguish fires in the battery pack 200. The firefighting device 500 is spaced apart on the side of the battery pack 200 facing away from the control device 600. A maintenance passage 300 is defined between the thermal management device 400, the firefighting device 500, and the battery pack 200. It should be noted that the firefighting device 500 can extinguish fires in the event of thermal runaway or even fire in the thermal management device 400.

[0045] In some embodiments of this application, please continue to refer to Figure 1 In this embodiment, the number of battery packs 200 is at least two, and the two battery packs 200 are spaced apart along the length direction b, and a maintenance channel 300 is defined between the two battery packs 200 .

[0046] In some embodiments, the battery pack 200 may be a single battery, a battery pack, a battery box, a battery cluster, or the like.

[0047] The advantages of this application are: through reasonable and safe electrical layout, strong and weak electricity are isolated and modularly partitioned, and a shorter maintenance channel 300 is set up to facilitate the escape of maintenance personnel and to prevent electric shock to the greatest extent during maintenance operations.

[0048] Furthermore, in order to better implement the mobile emergency energy storage device in any of the above embodiments, the present application also provides a mobile emergency energy storage device, including the above mobile emergency energy storage device and a traction device, the traction device is used to drive the mobile emergency energy storage device to move.

[0049] In some embodiments, the mobile emergency energy storage device is a charging vehicle.

[0050] In some embodiments of the present application, the traction device includes a traction head and a traction body of the device, the mobile emergency energy storage device is arranged on the traction body and close to the traction head, and the mobile emergency energy storage device includes a control device 600, which is arranged away from the traction head; wherein, a charging gun 800 is also provided on the side of the mobile emergency energy storage device where the control device 600 is arranged.
