[0033] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0034] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back) are merely 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, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0035] 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] This utility model provides a mobile energy storage vehicle, including a tractor unit, a transport vehicle body, and an energy storage container. The tractor unit and the transport vehicle body are connected. The transport vehicle body is used to carry the energy storage container.

[0037] The energy storage container has a reasonable internal layout and compact equipment arrangement, which allows it to accommodate more battery boxes and effectively improve the energy storage capacity. The specific solution is illustrated in the following embodiments.

[0038] Please see Figure 1 and Figure 2 The energy storage container 100 includes a container body 10 and a partition wall 20.

[0039] The container 10 can be a shipping container. The length of the container 10 is 23 to 25 feet, allowing conventional vehicle models to transport the energy storage container 100. It should be noted that the width of the container 10 can be the standard width of a shipping container according to ISO standards, and the height of the container 10 can also be the standard height of a shipping container according to ISO standards.

[0040] The enclosure 10 has a front wall 11 and a rear wall 12 at both ends, side walls 13 on both sides, and a top plate 14 and a bottom plate (not shown in the figure) at the top and bottom. Essentially, the enclosure 10 is formed by the front wall 11, rear wall 12, side walls 13, top plate 14, and bottom plate. A partition wall 20 is located inside the enclosure 10 to divide the internal space into a battery compartment 30, a liquid cooling compartment 40, and a fire-fighting electrical compartment 50.

[0041] Specifically, please refer to 2 to Figure 4 One side wall of the battery compartment 30 is the front wall 11. Multiple battery clusters 31 are disposed within the battery compartment 30. Each battery cluster 31 includes multiple battery boxes 311. Multiple battery clusters 31 are arranged along the length and width of the box body 10. For example, two battery clusters 31 are arranged along the width of the box body 10, and six battery clusters 31 are arranged along the length of the box body 10, which is equivalent to the battery clusters 31 within the battery compartment 30 being arranged in a 2x6 matrix.

[0042] Each battery cluster 31 includes multiple battery boxes 311 and a high-voltage box 312. The high-voltage box 312 and the multiple battery boxes 311 are arranged from bottom to top along the height direction of the container 10. Specifically, in some embodiments, the multiple battery boxes 311 form a battery assembly. The high-voltage box 312 is located below the battery assembly. In this embodiment, the energy storage container 100 is arranged on a transport vehicle, so the position of the high-voltage box 312 allows operators to operate and maintain the high-voltage box 312 while standing, without having to climb onto the vehicle, which improves the efficiency of the operators.

[0043] In other embodiments, the multiple battery boxes 311 may form multiple battery modules. The multiple battery modules are electrically connected to the high-voltage box 312. The high-voltage box 312 and the multiple battery modules are arranged sequentially from bottom to top along the height direction of the housing 10. For example, a battery cluster 31 includes eight battery boxes 311. Each group of four battery boxes 311 forms one battery module, therefore one battery cluster 31 includes two battery modules.

[0044] Further, see Figure 3 Along the length of the housing 10, the battery compartment 30 has multiple side doors 131 on both sides. For example, the number of side doors 131 on one side of the battery compartment 30 is the same as the number of battery clusters 31 arranged along the length of the housing 10. That is, the battery clusters 31 correspond to the side doors 131, so that the operator can open the side door 131 to maintain the battery cluster 31 corresponding to that side door 131.

[0045] See Figure 3 and Figure 5 In some embodiments, at least one air intake fan 32 is provided on the side door 131. At least one air outlet fan 33 is provided on the front wall 11. When an unexpected situation such as smoke or fire occurs in the battery compartment 30, the air intake fan 32 and the air outlet fan 33 are turned on to achieve air circulation and promptly exhaust smoke, combustible gases, etc., to the outside of the housing 10 to prevent combustible gases from accumulating and causing an explosion.

[0046] For example, the intake fan 32 is installed on the side door 131 away from the exhaust fan 33. When the intake fan 32 and the exhaust fan 33 are started, the airflow formed in the battery compartment 30 can pass through the entire battery compartment 30. Therefore, smoke, combustible gas and other substances generated by any battery cluster 31 in case of an accident can be effectively and timely discharged to the outside of the housing 10.

[0047] In some embodiments, two air intake fans 32 and two air outlet fans 33 are provided to achieve more efficient air circulation. The two air intake fans 32 and two air outlet fans 33 can be arranged at intervals along the height direction of the housing 10. One air intake fan 32 and one air outlet fan 33 can be located at the top of the housing 10, and the other air intake fan 32 and the other air outlet fan 33 can be located at the bottom of the housing 10, thereby ensuring uniform air circulation within the battery compartment 30.

[0048] Please see Figure 2 The liquid cooling compartment 40 and the fire-fighting electrical compartment 50 are located at the same end of the enclosure 10 and are arranged adjacent to each other along the width direction of the enclosure 10. One side wall of the fire-fighting electrical compartment 50 and the liquid cooling compartment 40 is the rear end wall 12 of the enclosure 10. It can be understood that the partition wall 20 divides the space inside the enclosure 10, excluding the battery compartment 30, into the liquid cooling compartment 40 and the fire-fighting electrical compartment 50, and the liquid cooling compartment 40 and the fire-fighting electrical compartment 50 are respectively located at two corners of the enclosure 10.

[0049] The length of the liquid cooling chamber 40 can be aligned with the length of the housing 10. A liquid cooler 41 is installed inside the liquid cooling chamber 40. The liquid cooler 41 is used to dissipate heat and control the temperature of each battery cluster 31 within the battery compartment 30, preventing the battery boxes 311 in the battery clusters 31 from overheating and causing performance degradation or even damage. Optionally, the liquid cooler 41 can be connected to the battery clusters 31 via liquid cooling pipes.

[0050] For ease of description, the side wall 13 of the enclosure 10 corresponding to the liquid cooling compartment 40 along its length is defined as the first side wall 132, and the side wall 13 of the enclosure corresponding to the fire electrical compartment 50 is defined as the second side wall 133.

[0051] In some embodiments, the liquid cooling chamber 40 has multiple ventilation openings on the side walls near the exterior of the housing 10, specifically on the area of ​​the first side wall 132 corresponding to the liquid cooling chamber 40 and the area of ​​the rear end wall 12 corresponding to the liquid cooling chamber 40, to maintain air circulation within the liquid cooling chamber 40 and facilitate heat dissipation of the liquid chiller 41. In other embodiments, ventilation openings may be provided only on the area of ​​the first side wall 132 corresponding to the liquid cooling chamber 40, or only on the area of ​​the rear end wall 12 corresponding to the liquid cooling chamber 40; the specific configuration can be determined according to actual needs and is not limited here.

[0052] See also Figure 2 In some embodiments, a water fire suppression interface 42 is provided in the area of ​​the rear wall 12 corresponding to the liquid cooling compartment 40. The water fire suppression interface 42 is located at the bottom of the container 10. The energy storage container 100 includes a pipe 43, one end of which is connected to the water fire suppression interface 42, and the other end of which passes through the partition wall 20 separating the battery compartment 30 and the liquid cooling compartment 40 and is located in the battery compartment 30. This allows operators to connect external water supply equipment to the water fire suppression interface 42 in case of an emergency such as a fire in the battery compartment 30, so that fire-fighting water can enter the battery compartment 30 through the pipe 43 to stop the fire.

[0053] See Figure 3 The fire electrical compartment 50 is equipped with fire-fighting components 51, which include fire-fighting equipment. A fire compartment door 133a is provided on the second side wall 133, which allows operators to open the fire compartment door 133a to load, unload, repair, and maintain the fire-fighting components 51 inside the fire electrical compartment 50.

[0054] See Figure 6 and Figure 7 For example, the fire protection component 51 includes a fire tank 511, a fire control host 512, a backup power supply 513, a fire power supply box 514, and a fire module box 515.

[0055] The fire extinguishing tank 511 contains fire extinguishing agent. Implementably, the fire extinguishing tank 511 can be located at the corner of the fire electrical compartment 50 near the battery compartment 30 and the liquid cooling compartment 40, to facilitate the installation of a fixing device for the fire extinguishing tank 511, thereby securing the fire extinguishing tank 511 and preventing it from tipping over when the energy storage container 100 moves with the vehicle.

[0056] The fire control host 512 is electrically connected to the fire tank 511, the intake fan 32, the exhaust fan 33, and other equipment. In the event of a fire or other emergency in the battery compartment 30, the fire control host 512 can control the activation of these devices. The fire control host 512 can be installed on the inner wall of the fire compartment door 133a, allowing operators to access and operate it directly from the fire compartment door 133a without entering the fire electrical compartment 50.

[0057] The fire power supply box 514 is electrically connected to the fire control host 512 and is used to supply power to the fire control host 512. In some embodiments, the fire power supply box 514 may also be electrically connected to other equipment and supply power to them.

[0058] The backup power supply 513 is electrically connected to the fire protection power supply box 514. In the event of an unexpected power outage, the backup power supply 513 can supply power to the fire protection power supply box 514 to ensure the normal operation of the fire control host 512. The fire protection module box 515 is used to control the logic module of the fire protection system. The fire protection power supply box 514, the backup power supply 513, and the fire protection module box 515 can be installed on the partition wall 20 separating the fire protection electrical compartment 50 and the battery compartment 30.

[0059] In some embodiments, a dehumidifier 52 is provided inside the fire-fighting electrical compartment 50. The dehumidifier 52 can be installed on the partition wall 20 separating the fire-fighting electrical compartment 50 and the battery compartment 30. The dehumidifier 52 is used to remove moisture from the air in the battery compartment 30, prevent condensation from occurring inside the battery compartment 30, reduce the risk of short circuits and fires inside the battery compartment 30, and improve the safety of the energy storage container 100.

[0060] The energy storage container 100 includes a junction box 53, which is located below the fire-fighting component 51 or the liquid cooler 41. Essentially, the junction box 53 is located within the fire-fighting electrical compartment 50 or the liquid cooler compartment 40. Compared to existing energy storage containers that place the junction box within the battery compartment or have a separate junction compartment for the junction box, this application effectively utilizes the space along the height of the container 100 within the fire-fighting electrical compartment 50 or the liquid cooler compartment 40, thereby increasing the volume of the battery compartment 30. This allows for the placement of more battery cells 311 within the battery compartment 30, effectively increasing the energy storage capacity of the energy storage container 100. Therefore, the total energy storage capacity of the battery compartment 30 in this application is not less than 5 MWh (megawatt-hour). This embodiment uses the example of the junction box 53 being located below the fire-fighting component 51 for illustration.

[0061] Please see Figure 7 and Figure 8 The junction box 53 is positioned below the fire-fighting assembly 51. This means that the fire tank 511, fire control host 512, backup power supply 513, and fire module box 515 in the fire-fighting assembly 51 are respectively positioned above the junction box 53. For example, the fire-fighting assembly 51 includes a battery assembly 516 for supplying power to the backup power supply 513. The battery assembly 516 and the fire tank 511 can be arranged on the junction box 53, meaning that the junction box 53 provides support for the battery assembly 516 and the fire tank 511, enhancing their stability.

[0062] The combiner box 53 is electrically connected to each battery cluster 31 to combine the current output from multiple battery clusters 31.

[0063] It should be noted that the junction box 53 is located below the fire-fighting component 51, meaning that the junction box 53 is located at the bottom of the container 10. However, this does not mean that the junction box 53 must be located on the bottom plate of the container 10. The energy storage container 100 may also have a support frame installed below the junction box 53, so that there is a gap between the bottom of the junction box 53 and the bottom plate of the container 10, forming a transition space. Some liquid cooling pipes and other lines can pass through the transition space to connect with the battery cluster 31.

[0064] Multiple charging bases 54 are provided at the bottom of the rear end wall 12 along the width direction of the housing 10. The charging bases 54 are electrically connected to the combiner box 53 and are used to connect to external devices so that external power can charge the battery box 311 through the charging bases 54, or the electrical energy stored in the charging pack can be discharged to external devices through the charging bases 54. Alternatively, external power can charge the battery box 311 through the charging bases 54, and the electrical energy stored in the charging pack can be discharged to external devices through the charging bases 54.

[0065] The energy storage container 100 also includes electrical components located inside the fire-fighting battery compartment 30. The electrical components include a converter 55, a distribution box 56, and a domain control unit 57.

[0066] The inverter 55 is electrically connected to the battery cluster 31. The inverter 55 controls the charging and discharging process of the battery cluster 31. The inverter 55 can also convert electrical energy, for example, converting direct current (DC) to alternating current (AC) for connection and energy exchange with the power grid or other AC loads; or converting AC to DC and outputting it to the battery box 311 in the battery cluster 31 for storage. The inverter 55 can be installed on the inner wall of the rear end wall 12.

[0067] The distribution box 56 is electrically connected to the converter 55 and the electrical load, and is used to distribute the power output from the converter 55 to the electrical load or equipment. The distribution box 56 can be installed on the inner wall of the second side wall 133. The distribution box 56 can also be electrically connected to the battery pack 516, so that the power in the battery pack 516 can supply power to the electrical load or equipment through the distribution box 56.

[0068] The domain controller 57 can consist of a BMS operator panel and a domain controller box, and the domain controller 57 is connected to the EMS. The domain controller 57 can be installed on the inner wall of the fire door 133a.

[0069] See Figure 6 An EMS control panel 58 can be installed at the bottom of the second side wall 133, that is, below the fire hatch 133a, so that operators can view and operate the energy storage system.

[0070] See Figure 8 In some embodiments, the energy storage container 100 includes an air conditioner 59, which is installed within the fire electrical compartment 50. The air conditioner 59 is one of the electrical loads that are electrically connected to the distribution box 56. The air conditioner 59 can be installed on the rear wall 12. The air conditioner 59 can be used to control the temperature within the fire electrical compartment 50, preventing overheating of the fire-fighting equipment in the fire-fighting assembly 51 and the equipment in the electrical assembly, which could affect their effectiveness or use.

[0071] The energy storage container 100 includes a charger assembly 60. The charger assembly 60 is located on the outside of the container body 10, which reduces the space required to store the charger 61 in a conventional energy storage container 100. This allows the volume of the battery compartment 30 to be further expanded, accommodating more battery boxes 311, thereby further increasing the energy storage capacity of the energy storage container 100.

[0072] The charger assembly 60 includes a charger 61 and a mounting bracket 62. The charger 61 is fixed to the front wall 11 of the housing 10 via the mounting bracket 62. The charger 61 is capable of outputting discharge to supply power to external electrical equipment, such as energy vehicles.

[0073] For example, the front wall 11 is positioned close to the front of the vehicle. Placing the charger 61 on the front wall 11 is equivalent to placing the charger 61 between the front of the vehicle and the housing 10, fully utilizing the space between the housing 10 and the front of the vehicle, making the structure of the mobile energy storage vehicle more compact. Simultaneously, this arrangement, compared to placing the charger 61 on the side wall 13 or rear wall 12 of the housing 10, can prevent the charger 61 from colliding with external objects when the mobile energy storage vehicle moves, thereby helping to extend the service life of the charger 61.

[0074] Two chargers 61 can be provided, which can charge multiple external devices at the same time, effectively improving charging efficiency.

[0075] In some embodiments, the charger assembly 60 includes a storage box 63 fixed to the front end wall 11. The storage box 63 stores cables, charging guns, etc. Exemplarily, the storage box 63 is positioned below the charger 61 to facilitate the operator's use of cables and charging guns.

[0076] The energy storage container 100 includes pressure relief windows 70, which are disposed on the top plate 14 of the container. Multiple pressure relief windows 70 are provided. For example, three pressure relief windows 70 are provided.

[0077] The above embodiments are merely illustrative examples of structures. The structures in each embodiment are not fixed combinations. In the absence of structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used.

[0078] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
