[0047] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0048] Refer to the following figure Figures 1 - 10 Describe the energy storage device 100 according to the embodiment of the present invention. The energy storage device 100 of the present invention is applicable to electronic devices.

[0049] Combined with Figure 1 As shown, the energy storage device 100 according to the embodiment of the present invention may mainly include: an energy storage cabinet 10, a battery module 20, a control module 30, and a temperature control module 40. Among them, the energy storage cabinet 10 includes a cabinet door 13 and a cabinet body 12. The cabinet door 13 and the cabinet body 12 cooperate to define an accommodation space 11, so that the interior of the energy storage cabinet 10 has a certain accommodation function. In the embodiment of the present invention, the battery module 20, the control module 30, and the temperature control module 40 are all arranged in the accommodation space 11, and the control module 30 is arranged above the battery module 20, so that the battery module 20, the control module 30, and the temperature control module 40 can be centrally arranged in the energy storage cabinet 10, which is beneficial to improving the integration of the battery module 20, the control module 30, and the temperature control module 40 in the energy storage cabinet 10.

[0050] In the prior art, there are two cavities on the left and right in the battery cabinet, and a partition is arranged between the two cavities on the left and right to separate the battery module from other modules such as the PCS component and the BMS component. Compared with the prior art, the partition structure inside the energy storage cabinet 10 in the embodiment of the present invention is cancelled, and the accommodation space 11 is a whole, so that the internal structure setting of the energy storage cabinet 10 can be simplified, which is beneficial to reducing the cost of electronic devices.

[0051] According to some embodiments of the present invention, the temperature control module 40 is at least partially arranged in the space between the control module 30 and the cabinet door 13. According to other embodiments of the present invention, the temperature control module 40 is at least partially arranged in the space between the battery module 20 and the cabinet door 13. Such an arrangement can improve the integration of the temperature control module 40 with the battery module 20 and the control module 30, and facilitate the temperature control module 40 to dissipate heat from the battery module 20 and the control module 30.

[0052] According to some embodiments of the present utility model, the control module 30 includes an energy storage inverter 31. According to some other embodiments of the present utility model, the control module 30 includes a filtering module 32. According to still some other embodiments of the present utility model, the control module 30 includes an energy storage inverter 31 and a filtering module 32. Specifically, the energy storage inverter 31 and the filtering module 32 can be designed according to the specific requirements of the energy storage device 100.

[0053] Combined with Figure 1 and Figure 6 As shown, the control module 30 in the embodiment of the present utility model includes an energy storage inverter 31 and a filtering module 32. The energy storage inverter 31 is arranged above the battery module 20, and the filtering module 32 is arranged above the energy storage inverter 31.

[0054] Specifically, the filtering module 32 and the energy storage inverter 31 are sequentially arranged above the battery module 20. This can not only facilitate the arrangement of the energy storage inverter 31 and the filtering module 32 in the energy storage cabinet 10 and the battery module 20 in a containing space 11, but also prevent the energy storage inverter 31 and the filtering module 32 from affecting the heat dissipation of the battery pack.

[0055] Combined with Figure 1 and Figure 6 As shown, the energy storage device 100 further includes a battery management system 33. The battery management system 33 is arranged above the battery module 20, or the battery management system 33 is arranged in the space between the battery module 20 and the cabinet door 13.

[0056] According to some embodiments of the present utility model, the battery management system 33 is arranged above the battery module 20. According to some embodiments of the present utility model, the battery management system 33 is arranged in the space between the battery module 20 and the cabinet door 13. With such an arrangement, the installation position of the battery management system 33 in the present utility model can be flexible, which is convenient for the arrangement of multiple structures in the energy storage cabinet 10. It should be noted that the installation position of the battery management system 33 in the energy storage cabinet 10 can be designed according to specific requirements.

[0057] Combined with Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the temperature control module 40 includes an air cooling part 41 and an air duct part 42. The air duct part 42 has an air inlet 421 and a first air outlet 422. The air inlet 421 is communicated with the air cooling part 41, and the first air outlet 422 is arranged facing the battery module 20. Specifically, the air cooling part 41 can generate cold air for cooling the battery module 20, which can ensure the working safety of the battery module 20.

[0058] The air duct member 42 is provided with an air inlet 421. The cold air in the air-cooling member 41 can enter the air duct member 42 through the air inlet 421 and then flow along the air duct member 42. One end of the air duct member 42 far from the air inlet 421 is provided with a first air outlet 422, so that the cold air in the air duct member 42 can flow out from the first air outlet 422. The cold air flowing out from the first air outlet 422 can directly blow towards the battery module 20. The cold air can exchange heat with the battery module 20 and take away the heat generated by the battery module 20. In this way, the heat generated when the battery module 20 works is taken away, the temperature of the battery module 20 can be reduced, and thus it can prevent too much heat accumulation in the battery module 20 from causing an explosion, which is beneficial to improving the working safety of the battery module 20.

[0059] Combined with Figures 2 - 7 As shown, the air duct member 42 includes a first air duct section 432, a second air duct section 433 and a third air duct section 434. The second air duct section 433 is arranged above the control module 30. The first air duct section 432 is connected to the front end of the second air duct section 433. The third air duct section 434 is connected to the rear end of the second air duct section 433. Both the first air duct section 432 and the third air duct section 434 are bent and extended downward relative to the second air duct section 433. The first air duct section 432 is provided with an air inlet 421, and the third air duct section 434 is provided with a first air outlet 422.

[0060] Specifically, in the energy storage cabinet 10, the air duct member 42 is bent and arranged to be suitable for guiding the cold air to the battery module 20 in the limited accommodation space 11. It can improve the heat dissipation efficiency of the battery module 20 while enhancing the structural compactness and integration of the air duct member 42 and the battery module 20, and thus is beneficial to reducing the size of the energy storage cabinet 10.

[0061] Combined with Figure 5 As shown, in the embodiment of the present utility model, the front end of the second air duct section 433 is the end of the second air duct section 433 close to the cabinet door 13, and the rear end of the second air duct section 433 is the end of the second air duct section 433 far from the cabinet door 13.

[0062] Furthermore, the first air duct section 432 is connected to the front end of the second air duct section 433 and is provided with an air inlet 421, so that the cold air generated by the air-cooling member 41 can first enter the first air duct section 432 and then flow from the first air duct section 432 into the second air duct section 433. The third air duct section 434 is connected to the rear end of the second air duct section 433 and is provided with a first air outlet 422, so that the cold air in the second air duct section 433 can flow into the third air duct section 434 and then flow towards the battery module 20 through the first air outlet 422 to dissipate heat and cool the battery module 20. With such an arrangement, the cold air generated by the air-cooling member 41 can flow towards the battery module 20 through the air duct member 42, which can ensure the heat dissipation effect of the temperature control module 40 on the battery module 20.

[0063] Further, both the first air duct section 432 and the third air duct section 434 are bent downward relative to the second air duct section 433, which can facilitate the connection between the first air duct section 432 and the air outlet above the air-cooling component 41, and can facilitate the downward extension of the first air outlet 422 on the third air duct section 434, and then correspond to the battery module 20.

[0064] With such a setting, the cold air generated by the air-cooling component 41 can flow through the first air duct section 432, the second air duct section 433, and the third air duct section 434 to the first air outlet 422 in sequence, and then flow from the first air outlet 422 in the front-back direction to the battery module 20.

[0065] Combined with Figures 2 - 7 As shown, the first air duct section 432 is located in the space between the control module 30 and the cabinet door 13. The first air duct section 432 is located above the air-cooling component 41, and the air inlet 421 is vertically and oppositely communicated with the air outlet of the air-cooling component 41. The third air duct section 434 is located in the space on the side of the battery module 20 and the control module 30 away from the cabinet door 13. With such a setting, on the one hand, after the cabinet door 13 is closed, the air-cooling component 41 can be directly connected to the air inlet 421 of the first air duct section 432, so that the cold air can directly enter the air duct component 42, which is convenient for operation. On the other hand, it can ensure that the cold air entering the second air duct section 433 can flow from front to back to enter the third air duct section 434 at the rear end of the second air duct section 433, which is beneficial to simplifying the layout of the air duct component 42 and improving the integration of the energy storage device 100.

[0066] According to some embodiments of the present invention, combined with Figure 4 As shown, a second air outlet 4331 is provided on the second air duct section 433, and the second air outlet 4331 is disposed opposite to the upper side of the control module 30. Specifically, the second air duct section 433 is located above the control module 30, and the second air outlet 4331 is provided at a position of the second air duct section 433 facing the control module 30, so that the cold air in the second air duct section 433 can flow toward the control module 30 below the second air duct section 433, so that the temperature control module 40 can dissipate heat from the control module 30.

[0067] It should be noted that in the embodiments of the present invention, the control module 30 can dissipate heat by relying on its own structure, but when the power of the control module 30 is relatively large, relying solely on its own structure cannot meet the heat dissipation requirements of the control module 30. At this time, it is necessary to borrow the temperature control module 40 to cool the control module 30.

[0068] According to other embodiments of the present invention, combined with Figure 5 As shown, the second air outlet 4331 is not provided on the second air duct section 433, and the control module 30 dissipates heat and cools by relying on its own structure.

[0069] Combined withFigure 2 and Figure 3 As shown in Figure 3 , the third air duct section 434 includes a main body plate 4341 and a wind deflector 4342. The wind deflector 4342 is disposed on the part of the main body plate 4341 corresponding to the control module 30. The first air outlet 422 is located below the wind deflector 4342. With such a setting, the cold air in the third air duct section 434 can be blocked from flowing towards the control module 30, so as to ensure the air volume flowing towards the battery module 20, and the heat dissipation reliability of the temperature control device for the battery module 20 can be ensured.

[0070] Combined with Figure 2 and Figure 3 As shown in Figure 2 and Figure 3 , the main body plate 4341 includes a main board portion 43411 and a first side plate portion 43412. The first side plate portion 43412 is disposed on the left and right sides and the lower side of the main board portion 43411 and extends towards the battery module 20 by bending relative to the main board portion 43411. The wind deflector 4342 is disposed on the part of the main body plate 4341 corresponding to the control module 30.

[0071] Specifically, in the third air duct section 434, the main body plate 4341 extends vertically to direct the cold air towards the first air outlet 422 below. In the main body plate 4341, the main body portion extends vertically, playing a major role in guiding the air flow. The first side plate portion 43412 is arranged on the circumference of the main body portion corresponding to the first air outlet 422 and extends towards the battery module 20 by bending. With such a setting, the first side plate portion 43412 can direct the air flowing to the first air outlet 422 towards the battery module 20, so as to increase the air volume flowing towards the battery module 20, and further improve the heat dissipation efficiency of the battery module 20.

[0072] Furthermore, the main body plate 4341 extends vertically and corresponds to both the control module 30 and the battery module 20. A wind deflector 4342 is disposed on the part of the main body plate 4341 corresponding to the controller. The wind deflector 4342 can block the air flow in the third air duct section 434 from flowing towards the control module 30. In this way, not only can the cold air leakage in the third air duct section 434 be avoided, the air volume blown towards the battery module 20 can be ensured, but also the air can be prevented from directly blowing on the control module 30, and the electrical connection reliability of the control module 30 can be ensured.

[0073] Combined with Figure 2 and Figure 3As shown, in the third air duct section 434, the air guiding channel 4343 jointly defined by the wind deflector 4342 and the main body plate 4341 is located above the first air outlet 422. The upper end of the air guiding channel 4343 is communicated with the second air duct section 433, and the lower end is communicated with the first air outlet 422. In this way, air can smoothly enter the air guiding channel 4343 and flow downward along the air guiding channel 4343, and then flow to the first air outlet 422. Such a setting can ensure the air volume of the first air outlet 422 and the heat dissipation effect of the temperature regulation module 40 on the battery module 20.

[0074] Combined with Figure 2 As shown, an installation bracket 43421 is arranged on the side of the wind deflector 4342 facing the control module 30, and at least part of the installation bracket 43421 is connected and fixed to the control module 30. Specifically, the wind deflector 4342 is located between the main body plate 4341 and the control module 30. The wind deflector 4342 has a certain structural strength. Arranging the installation bracket 43421 on the wind deflector 4342 can be used to fix the energy storage converter 31 in the control module 30 and ensure the structural reliability of the energy storage converter 31.

[0075] Combined with Figure 2 、 Figure 4 and Figure 5 As shown, the first air outlet 422 extends in the up and down direction and at least partially corresponds to the battery module 20. Specifically, in the embodiment of the present invention, a plurality of battery modules 20 are arranged at intervals in the up and down direction in the accommodation space 11, and a gap 21 is left between two adjacent battery modules 20. Therefore, there are a plurality of gaps 21 in the up and down direction of the battery module 20. The first air outlet 422 extends in the up and down direction, so that the first air outlet 422 can correspond to each layer of gaps 21 in the battery module 20 in the up and down direction. Under the action of inertia, the cold air flowing to the first air outlet 422 can enter each layer of gaps 21 in the battery module 20, and then cool the plurality of battery modules 20 arranged at intervals in the up and down direction at the same time. In this way, the heat dissipation uniformity of the battery module 20 can be improved, and the heat dissipation effect of the battery module 20 can be effectively improved.

[0076] In the embodiment of the present invention, the temperature regulation module 40 cools the battery module 20 by single-sided air intake, which is suitable for scenarios with low energy density. When the energy density of the battery module 20 is relatively high, single-sided air intake cooling may not meet the cooling requirements of the battery module 20. The following combines Figures 8 - 10 to describe the embodiment of the temperature regulation module 40 in the present invention for double-sided air intake cooling of the battery module 20.

[0077] Combined with Figure 1 、 Figure 8 、 Figure 9 and Figure 10As shown, the first air duct section 432 is located in the space between the control module 30 and the cabinet door 13. The first air duct section 432 is located above the air-cooling component 41, and the air inlet 421 and the air outlet of the air-cooling component 41 are arranged in an up-and-down opposite communication manner. With such an arrangement, after the cabinet door 13 is closed, the air-cooling component 41 can be directly connected to the air inlet 421 of the first air duct section 432, so that cold air can directly enter the air duct component 42, which is convenient for operation.

[0078] Further, there are two third air duct sections 434. One of the two third air duct sections 434 is located in the space between the battery module 20 and the cabinet door 13, and the other of the two third air duct sections 434 is located in the space on the side of the battery module 20 away from the cabinet door 13. In this way, the air duct component 42 is provided with first air outlets 422 in both the front and rear directions with respect to the battery module 20, so that cold air can blow towards the battery module 20 from both the front and rear directions. With such an arrangement, the heat dissipation uniformity of the battery module 20 can be further improved, which is beneficial to improving the heat dissipation effect of the battery module 20 and enhancing the working safety of the battery module 20.

[0079] Combined with Figure 8 、 Figure 9 and Figure 10 As shown, the air duct component 42 includes a fourth air duct section 435 and a fifth air duct section 436. The fourth air duct section 435 is arranged at intervals below the second air duct section 433 and is located between the battery module 20 and the control module 30. The fifth air duct section 436 is connected between the second air duct section 433 and the fourth air duct section 435 and is located on at least one side of the control module 30 in the left-right direction. The two third air duct sections 434 are arranged on both sides of the fourth air duct section 435 in the front-rear direction and are arranged to extend downward and bend relative to the fourth air duct section 435.

[0080] Specifically, in the embodiment of the present invention, the fourth air duct section 435 and the second air duct section 433 are arranged at an up-and-down interval, and the fifth air duct section 436 is connected between the second air duct section 433 and the fourth air duct section 435, so that the cold air in the second air duct section 433 can flow into the fourth air duct section 435 through the fifth air duct section 436.

[0081] Further, the third air duct sections 434 that bend downward are connected and arranged on both sides of the fourth air duct section 435 in the front-rear direction, and the two fifth air duct sections 436 are located on at least one side of the fourth air duct section 435 and the second air duct section 433 in the left-right direction. With such an arrangement, the fifth air duct section 436 can be arranged to avoid the third air duct section 434, and the structural design of the air duct component 42 in the embodiment of the present invention can be made more flexible.
