[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the fixed scope of the present utility model.

[0038] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0039] This application discloses an energy storage device, which includes a housing 10, a battery compartment 11 disposed within the housing 10, the battery compartment 11 having a first air inlet 111 and a first air outlet 112; multiple battery clusters 20, which are spaced apart within the battery compartment 11, each battery cluster 20 having a converter 21 at its top, the converter 21 having a first heat dissipation channel 211 communicating with the first air inlet 111; and a heat sink 30 disposed on the top of the multiple converters 21, the heat sink 30 having a second heat dissipation channel 31, each of the first heat dissipation channels 211 communicating with the second heat dissipation channel 31, the second heat dissipation channel 31 communicating with the first air outlet 112.

[0040] This application discloses an energy storage device that can serve as a power source to provide electrical energy to electrical equipment. For example, the energy storage device can be installed on a vehicle body 100 to form a mobile energy storage vehicle, which offers advantages such as safety, convenience, and environmental friendliness. Of course, in this application embodiment, no excessive restrictions are placed on the specific application of the energy storage device; any application is permitted.

[0041] The following will use the application of an energy storage device in a mobile energy storage vehicle as an example to illustrate this application. The mobile energy storage vehicle includes a vehicle body 100 and an energy storage device, which is mounted on the vehicle body 100.

[0042] The energy storage device disclosed in this application includes a cabin 10. The cabin 10 can be a cuboid structure, a cube structure, or other irregular structures. In this application embodiment, no excessive restrictions are placed on the specific structure of the cabin 10. In practical applications, those skilled in the art can set it as needed.

[0043] The following will use the rectangular structure of the cabin 10 as an example to explain the relevant aspects of this application.

[0044] In this embodiment of the application, the length direction of the cabin 10 is set as the first direction X, and the height direction of the cabin 10 is set as the second direction Y, and the second direction Y intersects with the first direction X.

[0045] like Figure 1As shown, along the first direction X, the cabin 10 includes a liquid cooling cabin 12, a battery cabin 11, an equipment cabin 13, and a charging cabin 14 arranged sequentially. A partition 50 is provided between adjacent cabins to separate them. The battery cabin 11 has a first air inlet 111 and a first air outlet 112. Multiple battery clusters 20 are disposed within the battery cabin 11. Gas can enter the battery cabin 11 through the first air inlet 111 to cool the battery clusters 20, and then flow out of the battery cabin 11 through the first air outlet 112.

[0046] It should be noted that the battery clusters 20 in this embodiment include multiple clusters, all of which are vertically arranged and spaced apart within the battery compartment 11. For example, a first support is provided within the battery compartment 11, the first support being vertically arranged, and one end of the first support being fixedly connected to the bottom wall of the battery compartment 11. The battery clusters 20 are fixedly connected to the first support to secure them, ensuring that the battery clusters 20 are vertically arranged within the battery compartment 11.

[0047] The battery cluster 20 comprises multiple battery packs, a main control box, and an inverter 21 arranged sequentially from bottom to top. Due to the significant weight of the battery packs, placing them at the bottom of the battery cluster 20 lowers its center of gravity, increasing the safety and stability of the energy storage device. The battery packs store electrical energy. The main control box, as the core management unit of the battery cluster 20, can collect parameters such as voltage, current, temperature, and insulation resistance of the battery cluster 20 in real time. The inverter 21 converts the direct current (DC) from the battery packs into alternating current (AC) for use by the load.

[0048] It should be noted that, in this embodiment, each battery cluster 20 includes multiple battery packs, a main control box, and an inverter 21 arranged sequentially from bottom to top. That is, each battery cluster 20 has an inverter 21 at its top, which converts the DC power in the corresponding multiple battery packs into AC power.

[0049] like Figure 2 As shown, each converter 21 includes a converter body and a first heat dissipation channel 211 disposed on one side of the converter body. The first heat dissipation channel 211 has an opening. Gas can enter the battery compartment 11 from the first air inlet 111, and then enter the corresponding first heat dissipation channel 211 from each opening to carry away the heat generated by the converter body and achieve the cooling of the converter body.

[0050] In this embodiment, a heat sink 30 is provided on the top of multiple inverters 21, and the heat sink 30 has a second heat dissipation channel 31. Each first heat dissipation channel 211 is connected to the second heat dissipation channel 31, and gas flows from the first heat dissipation channel 211 into the second heat dissipation channel 31. The second heat dissipation channel 31 is connected to the first air outlet 112, and gas can flow out of the battery compartment 11 from the second heat dissipation channel 31 through the first air outlet 112.

[0051] In this embodiment, multiple battery clusters 20 are arranged inside the battery compartment 11. Each battery cluster 20 has a converter 21 on its top. The converter 21 converts the DC power provided by the battery cluster 20 into AC power and supplies the AC power to the load. Each converter 21 has a first heat dissipation channel 211, which is connected to the first air inlet 111 of the battery compartment 11. A heat sink 30 is arranged on the top of the multiple converters 21. The heat sink 30 has a second heat dissipation channel 31, which is connected to the first air outlet 112. It can be understood that the gas entering through the first air inlet 111 can enter each first heat dissipation channel 211, carrying away the heat dissipated by the converter body to reduce the temperature of the converter body. The gas then enters the second heat dissipation channel 31 from each first heat dissipation channel 211 and flows out from the first air outlet 112. The above configuration includes a corresponding first heat dissipation channel 211 for each converter body to dissipate heat, which can improve the heat dissipation efficiency of the energy storage device and improve the reliability of the energy storage device.

[0052] In some embodiments, such as Figure 2 As shown, the energy storage device also includes multiple air guide shrouds 40, each of which is connected between a first heat dissipation channel 211 and a second heat dissipation channel 31.

[0053] like Figure 2 As shown, a shroud 40 is connected between each inverter 21 and the heat sink 30. One end of the shroud 40 is connected to the first heat dissipation channel 211, and the other end is connected to the second heat dissipation channel 31. The gas flowing out of each first heat dissipation channel 211 can flow into the corresponding shroud 40, then flow from the shroud 40 into the second heat dissipation channel 31, and finally flow out of the battery compartment 11 from the first air outlet 112.

[0054] In this embodiment, an air guide shroud 40 is connected between each first heat dissipation channel 211 and second heat dissipation channel 31. The air guide shroud 40 conducts the corresponding first heat dissipation channel 211 and second heat dissipation channel 31 to further improve the heat dissipation efficiency and reliability of the energy storage device. This avoids the air flowing out of the two oppositely arranged first heat dissipation channels 211 blowing against each other, which would affect the heat dissipation efficiency of the energy storage device.

[0055] In some embodiments, such as Figure 2 As shown, the heat sink 30 includes a first sub-heat sink 32, a flexible heat sink 33, and a second sub-heat sink 34 connected in sequence. The second heat dissipation channel 31 is disposed within the first sub-heat sink 32, the flexible heat sink 33, and the second sub-heat sink 34. One end of each air guide shroud 40 is connected to a first heat dissipation channel 211, and the other end is connected to the second heat dissipation channel 31 within the first sub-heat sink 32; or, the other end is connected to the second heat dissipation channel 31 within the second sub-heat sink 34.

[0056] like Figure 2 As shown, the heat sink 30 in this embodiment includes three parts: a first sub-heat sink 32, a second sub-heat sink 34, and a flexible heat sink 33 connected between the first sub-heat sink 32 and the second sub-heat sink 34. A second heat dissipation channel 31 is disposed within the first sub-heat sink 32, the flexible heat sink 33, and the second sub-heat sink 34.

[0057] Along the extension direction of the heat sink 30, the flexible heat sink 33 has a certain degree of extensibility, which can absorb the tolerances of the first sub-heat sink 32 and the second sub-heat sink 34 during processing and installation, reduce the processing standards of the heat sink 30, and improve the installation efficiency of the heat sink 30.

[0058] For example, the flexible heat sink 33 can be made of canvas. Of course, the flexible heat sink 33 can also be made of other materials. In this embodiment, no particular restrictions are placed on the specific material of the flexible heat sink 33. In practical applications, those skilled in the art can choose according to their needs.

[0059] like Figure 2 As shown, one end of each air guide shroud 40 is connected to a first heat dissipation channel 211, and the other end of each air guide shroud 40 is connected to a second heat dissipation channel 31 within the first sub-heat dissipation component 32; or, the other end of each air guide shroud 40 is connected to a second heat dissipation channel 31 within the second sub-heat dissipation component 34. This allows the corresponding first heat dissipation channel 211 and second heat dissipation channel 31 to be connected through the air guide shroud 40, thereby further improving the heat dissipation efficiency and reliability of the energy storage device. It also prevents the gas flowing from the two oppositely arranged first heat dissipation channels 211 from blowing against each other, which would affect the heat dissipation efficiency of the energy storage device.

[0060] In some embodiments, such as Figure 4As shown, the cabin 10 has a first direction X, which is the length direction of the cabin 10. The cabin 10 also includes a liquid cooling cabin 12, an equipment cabin 13, a charging cabin 14, and a partition 50. Along the first direction X, the liquid cooling cabin 12 is located on one side of the battery cabin 11, and the equipment cabin 13 and the charging cabin 14 are located on the other side of the battery cabin 11. Adjacent cabins are separated by a partition 50. A first air inlet 111 is located on the partition 50 between the liquid cooling cabin 12 and the battery cabin 11, and a first air outlet 112 is located on the partition 50 between the battery cabin 11 and the equipment cabin 13. The energy storage device also includes a first fan 60, which is located in the equipment cabin 13 and connected to the first air outlet 112. The first fan 60 is adapted to draw out gas from the second heat dissipation channel 31.

[0061] like Figure 4 As shown, along the first direction X, the cabin 10 contains a liquid cooling cabin 12, a battery cabin 11, an equipment cabin 13, and a charging cabin 14 arranged sequentially, with adjacent cabins separated by a partition 50. The liquid cooling cabin 12 is located at the front of the vehicle body 100, near the front of the vehicle. The liquid cooling cabin 12 houses a liquid chiller, perfluorohexanone fire suppression cylinders, etc. The battery cabin 11 contains multiple battery clusters 20; exemplarily, the battery cabin 11 contains eight battery clusters 20, with each vertical column forming one cluster. Each battery cluster 20 includes, from bottom to top, five battery packs, a main control box, and a converter 21. The main liquid cooling pipe is located at the bottom of the battery cluster 20, using a bottom-in, bottom-out piping method, while the cable routing is located at the top of the battery cluster 20, separating water and electricity to improve the electrical safety and ease of installation of the energy storage device.

[0062] The equipment compartment 13 houses a monitoring cabinet, a power distribution cabinet, and charging piles. The power distribution cabinet is equipped with an AC combiner system, an auxiliary power system, an uninterruptible power supply, and a backup battery, providing 2 hours of backup power. The bottom of the charging compartment 14 contains a cable reel and a charging gun. The charging gun is electrically connected to the charging pile in the equipment compartment 13, allowing for separate compartment placement of the charging gun and charging pile for convenient use. The top of the charging compartment 14 serves as a heat dissipation channel.

[0063] like Figure 4 As shown, the first air inlet 111 is disposed on the partition 50 between the liquid cooling chamber 12 and the battery chamber 11, and the first air outlet 112 is disposed on the partition 50 between the battery chamber 11 and the equipment chamber 13, so as to improve the convenience of the placement of the first air inlet 111 and the first air outlet 112.

[0064] In this embodiment, the first fan 60 is disposed inside the equipment compartment 13 and is connected to the partition 50 between the battery compartment 11 and the equipment compartment 13 for fixing the first fan 60. Furthermore, the first fan 60 is connected to the first air outlet 112, and the first fan 60 draws out gas from the second heat dissipation channel 31 to improve the outflow efficiency of gas in the second heat dissipation channel 31 and improve the heat dissipation efficiency of the energy storage device.

[0065] It should be noted that the first fan 60 in this embodiment may include multiple fans. For example, the first fan 60 may include 2, 3, 4, 5, 6, etc. In this embodiment, the specific number of the first fan 60 is not limited. In practical applications, those skilled in the art can set it as needed.

[0066] In some embodiments, such as Figure 4 As shown, the equipment compartment 13 has a second air outlet 131, which is disposed on the partition 50 between the equipment compartment 13 and the charging compartment 14; the energy storage device also includes a second fan 70, which is disposed in the charging compartment 14 and connected to the second air outlet 131. The second fan 70 is adapted to draw out the gas in the equipment compartment 13.

[0067] like Figure 4 As shown, a second air outlet 131 is provided on the partition 50 between the equipment compartment 13 and the charging compartment 14. Along the first direction X, the second air outlet 131 is at least partially opposite to the first air outlet 112, so that the gas flowing out of the first air outlet 112 can more easily flow out of the equipment compartment 13 from the second air outlet 131 and enter the charging compartment 14.

[0068] In this embodiment, the second fan 70 is disposed inside the charging chamber 14 and connected to the partition 50 between the device chamber 13 and the charging chamber 14 for fixing the second fan 70. Furthermore, the second fan 70 is connected to the second air outlet 131, drawing gas from the device chamber 13 into the charging chamber 14, thereby improving the gas outflow efficiency from the device chamber 13 and enhancing the heat dissipation efficiency of the energy storage device.

[0069] It should be noted that the second fan 70 in this embodiment may include multiple fans. For example, the second fan 70 may include 4, 5, 6, 7, 8, etc. In this embodiment, the specific number of the second fan 70 is not limited. In practical applications, those skilled in the art can set it as needed.

[0070] In some embodiments, such as Figure 4As shown, the liquid cooling chamber 12 is provided with louvers 121. Along the first direction X, the louvers 121 are at least partially opposite to the first air inlet 111. The louvers 121 are suitable for gas outside the chamber 10 to flow into the liquid cooling chamber 12.

[0071] like Figure 4 As shown, the liquid cooling chamber 12 is equipped with louvers 121, allowing gas from outside the chamber 10 to flow into the liquid cooling chamber 12. Furthermore, the louvers 121 can block impurities, preventing them from entering the liquid cooling chamber 12 and affecting the reliability of the energy storage device.

[0072] Along the first direction X, the louver 121 is at least partially opposite to the first air inlet 111, so that the gas flowing in from the louver 121 can more easily flow into the battery compartment 11 from the first air inlet 111 to cool the battery cluster 20 in the battery compartment 11, improve the heat dissipation efficiency of the battery cluster 20, and improve the reliability of the energy storage device.

[0073] In some embodiments, such as Figure 4 As shown, the charging chamber 14 is provided with a third air outlet 141. Along the first direction X, the third air outlet 141 is at least partially opposite to the second air outlet 131. The third air outlet 141 is suitable for the gas inside the charging chamber 14 to flow out.

[0074] like Figure 4 As shown, the charging chamber 14 is provided with a third air outlet 141, through which the gas inside the charging chamber 14 can flow out of the charging chamber 14 and into the outside of the chamber body 10.

[0075] Along the first direction X, the third air outlet 141 is at least partially positioned opposite the second air outlet 131. This allows the gas flowing into the charging chamber 14 from the second air outlet 131 to more easily flow out of the charging chamber 14 from the third air outlet 141 and reach the outside of the chamber 10, thereby improving the gas outflow efficiency, the heat dissipation efficiency of the energy storage device, and the reliability of the energy storage device.

[0076] In some embodiments, such as Figure 5 As shown, the cabin 10 has a second direction Y, which is the height direction of the cabin 10; the charging cabin 14 includes a first sub-cabin 142 and a second sub-cabin 143 arranged at intervals along the second direction Y, and a third air outlet 141 is disposed on the side wall of the first sub-cabin 142; the energy storage device also includes a charging pile 80, which is disposed in the second sub-cabin 143.

[0077] like Figure 5As shown, the charging compartment 14 includes a first sub-compartment 142 and a second sub-compartment 143 spaced apart along the second direction Y, and the first sub-compartment 142 and the second sub-compartment 143 are separated by a partition. The first sub-compartment 142 is a heat dissipation channel, and a third air outlet 141 is disposed on the side wall of the first sub-compartment 142 away from the equipment compartment 13, and is arranged opposite to the second air outlet 131 along the first direction X. The gas flowing out of the second air outlet 131 can enter the first sub-compartment 142 and flow out of the charging compartment 14 through the third air outlet 141 to reach the outside of the compartment 10.

[0078] The charging pile 80 is located in the second sub-chamber 143, and the gas in the first sub-chamber 142 will not enter the second sub-chamber 143. This helps to improve the user experience and avoids the user feeling the heat of the gas while using the charging pile 80, which would affect the user experience.

[0079] In some embodiments, the energy storage device further includes a dustproof component 90, such as... Figure 6 As shown, the dustproof component 90 is provided with a plurality of through holes 91 at intervals; the first heat dissipation channel 211 has an opening away from the second heat dissipation channel 31, and the dustproof component 90 is connected to the converter 21 and covers the opening.

[0080] In this embodiment, the first heat dissipation channel 211 has an opening away from the second heat dissipation channel 31. The dustproof component 90 is connected to the converter 21 and covers the opening, so as to prevent impurities from entering the heat dissipation channel and affecting the reliability of the energy storage device.

[0081] It should be noted that the dustproof component 90 is provided with multiple through holes 91 at intervals, so that gas can enter the first heat dissipation channel 211 through the multiple through holes 91 and dissipate heat from the converter 21.

[0082] This application also discloses a mobile energy storage vehicle, which includes the energy storage device and vehicle body 100 described in the above embodiments, with the energy storage device disposed on the vehicle body 100.

[0083] This application discloses a mobile energy storage vehicle, which includes a front end, a vehicle body 100 connected to the front end, and the energy storage device described in the above embodiments. The energy storage device is mounted on the vehicle body 100, and the liquid-cooled compartment 12 is located near the front end. This energy storage vehicle offers advantages such as high safety, high flexibility, and environmental friendliness.

[0084] It should be noted that the energy storage device included in the mobile energy storage vehicle disclosed in this application has the same structure as the energy storage device described in the above embodiments, and its beneficial effects are also similar. Therefore, further details will not be provided here.

[0085] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0086] Although alternative embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make further changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the alternative embodiments as well as all changes and modifications falling within the scope of the present invention.

[0087] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used merely to distinguish one entity from another, and do not necessarily require or imply any such actual relationship or order between these entities.
