For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] See also Figures 1 to 7As shown, an embodiment of the present application provides an energy storage system, including: a cabinet shell 0121, a plurality of battery packs (not shown), a door body 0122 and an air conditioning device (not shown). The cabinet shell 0121 has a battery cavity and an opening connected to the battery cavity. Each of the battery packs is arranged in the battery cavity. The door body 0122 is movably connected to the cabinet shell 0121, and the door body 0122 is used to open or close the opening. An installation box 02 is arranged inside the door body 0122. The air conditioning device is arranged in the installation box 02. The energy storage system of the present application sets the air-conditioning device in the installation box 02 on the inner side of the door body 0122, so that the air-conditioning device is completely set in the cabinet shell 0121. The air-conditioning device has no exposed structure on the side of the door body 0122 or the back plate, so that the appearance structure of the energy storage system is regular and beautiful, and the installation box 02 has a protective effect on the air-conditioning device, which is not easy to collide with external objects, thereby ensuring the safety of the air-conditioning device. The distance between the air-conditioning device and the battery pack is relatively close, which has a good effect on cooling and regulating the temperature of the battery pack set inside the cabinet shell 0121.

[0049] like Figures 4 to 7 As shown, the energy storage system includes an air outlet duct shell 03, the installation box 02 has an air supply port 021 and an air return port 022, and a split air duct shell 04 is arranged on the top of the cabinet shell 0121, and the split air duct shell 04 is connected to the battery cavity. One end of the air outlet duct shell 03 is connected to the installation box 02, and the other end of the air outlet duct shell 03 extends to the split air duct shell 04, and the air outlet duct shell 03 is respectively connected to the air supply port 021 and the split air duct shell 04. The door body 0122 is provided with a breathable grid portion 01222, and a vent 023 is arranged on the side of the installation box 02 away from the air outlet duct shell 03, and the vent 023 and the breathable grid portion 01222 are located opposite to each other. The cooling air generated by the air conditioning device enters the air outlet duct shell 03 from the air supply port 021. The air outlet duct shell 03 has a cooling air channel. The cooling air passes through the cooling air channel and enters the diverter duct shell 04. The diverter duct shell 04 diverts the cooling air and then sends it into the battery cavity to perform heat exchange on the battery packs in the battery cavity, so as to achieve cooling and lowering the temperature of each battery pack. After the heat exchange, the temperature of the cooling air rises to form a return air, which then enters the return air port 022 and is directly discharged from the cabinet through the vent 023, or is recycled after being cooled by the air conditioner, such as entering the air outlet duct shell 03 and the diverter duct shell 04 in turn from the air supply port 021 to enter the battery cavity to cool down the battery packs in the battery cavity.

[0050] In one possible embodiment, Figure 6 and Figure 7As shown, the air outlet duct shell 03 includes a connecting duct 031 and an extending duct 032. The connecting duct 031 is connected to the installation box 02, and the connecting duct 031 is connected to the air supply port 021. The extending duct 032 is located between the installation box 02 and the battery pack, one end of the extending duct 032 is connected to the connecting duct 031, and the other end of the extending duct 032 extends toward the diversion duct shell 04. There is a gap between the extending duct 032 and the installation box 02. The position of the extending channel is opposite to the return air port 022, and the gap is formed between the extending duct 032 and the return air port 022. The return air channel is formed between the two sides of the extending channel and the two sides of the installation box 02. Such a structure is conducive to the smooth flow of the return air into the return air port 022.

[0051] like Figure 6 and Figure 7 As shown, a middle return air channel 0321 is provided on the extended air duct 032, and the middle return air channel 0321 is arranged opposite to the return air port 022. The middle return air channel 0321 and the two sides of the extended air duct 032 are connected to the return air port 022 and the battery cavity. A fan is provided on each of the battery packs. After the cooling air enters the battery cavity, the fan sucks the cooling air into the battery pack. The cooling air fully exchanges heat with each battery module or battery cell in the battery pack, forming the return air with a higher temperature. The two sides of the extended air duct 032 and the middle return air channel 0321 form a return channel for the return air. The return air can enter the return air port 022 via the middle return air channel 0321 and the channels on both sides of the extended air duct 032. The middle return air channel 0321 is opposite to the return air port 022, which facilitates the return air to enter the return air port 022 more quickly.

[0052] In one possible embodiment, Figure 1 As shown, the energy storage system includes two door bodies 0122, and the two door bodies 0122 are respectively movably connected to the cabinet shell 0121. The two door bodies 0122 are respectively provided with an air conditioning device. The energy storage system includes two battery cavities, and each battery cavity is respectively provided with a door body 0122, and the door bodies 0122 are provided with an air conditioning device. Each battery pack is arranged in sequence from top to bottom in the corresponding battery cavity.

[0053] like Figure 4As shown, the two sides of the split air duct shell 04 have ventilation gaps a connected to the battery cavity. A splitter plate 041 is arranged in the split air duct shell 04. The middle part of the splitter plate 041 protrudes toward the outlet air duct shell 03, and the two sides of the splitter plate 041 extend along the corresponding ventilation gaps a respectively. The cooling air passes through the splitter plate 041 and is guided to the ventilation gaps a on both sides of the split air duct shell 04, and then the cooling air is guided into the battery cavity by the ventilation gaps a.

[0054] like Figure 2 and Figure 3 As shown, the cabinet shell 0121 has a plurality of inner plates 01211, and the battery cavity is formed between two adjacent inner plates 01211. The split air duct shell 04 includes a bottom shell 042 and a top shell 043, and the bottom shell 042 and the top shell 043 are both located between the two inner plates 01211 and are respectively connected to the inner plates 01211 on both sides. The ventilation gap a is formed between the bottom shell 042 and the inner plates 01211 on both sides. The splitter plate 041 is located between the bottom shell 042 and the top shell 043. A splitter cavity is formed between the splitter plate 041 and the bottom shell 042 and the top shell 043, and the cooling air is split into the ventilation gaps a on both sides of the splitter cavity, and then enters the battery cavity.

[0055] In one possible embodiment, Figure 2 As shown, a back plate 01212 is provided on the side of the cabinet shell 0121 opposite to the door body 0122. In the direction from the opening of the cabinet shell 0121 to the back plate 01212 of the cabinet shell 0121, the width of the ventilation gap a gradually decreases. The more the cooling air flows toward the back plate 01212, the smaller the air volume of the cooling air is, and the smaller the air volume distribution is. If the width of the ventilation gap a is kept constant, the air volume of the cooling air flowing to the back plate 01212 is very small, which is not conducive to the uniform distribution of the cooling air in the battery cavity, making the cooling effect of the battery pack uneven and the cooling effect of the battery pack poor. The width of the ventilation gap a is set to gradually decrease, so that the width of the ventilation gap a becomes narrower toward the back plate side, which can effectively increase the flow speed of the cooling air, facilitate the cooling air to flow to the side close to the back plate 01212, and enable the cooling air to be evenly distributed to the ventilation gap a.

[0056] In the direction from the top of the battery cavity to the bottom of the battery cavity, the gap between the inner plates 01211 on both sides of the battery cavity gradually decreases. It can also be understood that in the direction from the top of the battery cavity to the bottom of the battery cavity, the gap between each of the battery packs and the corresponding inner plates 01211 and is getting smaller and smaller. The cooling air enters the battery cavity through the ventilation gap a. The cooling air flows downward and the wind speed decreases, so that the battery packs near the bottom of the battery cavity are allocated very little cooling air. The gap between each of the battery packs and the corresponding inner plates 01211 and is getting smaller and smaller, which can help to increase the wind speed of the cooling air, so that the battery packs near the bottom layer can receive more cooling air. The fan in each of the battery packs will blow the cooling air into the battery pack, and the cooling air will fully cool and adjust the temperature of the battery module inside the battery pack, thereby achieving cooling treatment of the battery pack.

[0057] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model has been disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this patent can make some changes or modify the technical content suggested above into an equivalent embodiment with equivalent changes without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still falls within the scope of the solution of the utility model.
