[0033] Figure 1 This is a structural schematic diagram of an energy storage box according to an embodiment of the present utility model. Figure 1 As shown, an energy storage device A is installed inside an energy storage box 10. The energy storage box 10 includes a control module 100, a first temperature acquisition module 200, a heat preservation module 300, a heat dissipation module 400, and a partition 500. The energy storage box 10 is divided into an upper box 11 and a lower box 12 by the partition 500. The energy storage device A is installed on the partition 500. The control module 100 is connected to the first temperature acquisition module 200, the heat preservation module 300, and the heat dissipation module 400. The first temperature acquisition module 200 is installed on the surface of the energy storage device A and is used to acquire the temperature data of the energy storage device A. The heat preservation module 300 is installed at the air inlet of the upper box 10, and the heat dissipation module 400 is installed at the air outlet of the upper box 10. The control module 100 is used to generate a temperature control signal based on the temperature data. The heat preservation module 300 adjusts the opening area based on the temperature control signal, and the heat dissipation module 400 adjusts the air volume based on the temperature control signal.

[0034] Specifically, energy storage device A can be a flow battery or other energy storage device. Energy storage device A is housed within energy storage tank 10, which forms an isolation barrier between energy storage device A and the outside air, preventing physical corrosion. Simultaneously, temperature control maintains a suitable temperature within energy storage tank 10 for long-term storage of energy storage device A. Temperature acquisition module 200 can be located on the outer surface of energy storage device A to more accurately acquire its temperature data. Control module 100 can be a microcontroller unit. Control module 100 receives the temperature data acquired by temperature acquisition module 200 and, in conjunction with the ambient temperature, outputs temperature control signals to insulation module 300 and heat dissipation module 400 to control these modules, thereby adjusting the efficiency of heat exchange between energy storage tank 10 and the outside air, and controlling the temperature within energy storage tank 10. For example, as shown... Figure 1 As shown, the control module 100 can be installed inside the energy storage box 10. The energy storage box 10 is divided into an upper box 11 and a lower box 12, which are partially separated by a partition 500. The unpartitioned portion connects the upper box 11 and the lower box 12. The energy storage device A can be installed on the partition 500. The lower box 12 can be used to store the electrolyte for the operation of the energy storage device A. An air inlet is provided on one side of the upper box 11 of the energy storage box 10 for heat exchange with the outside air. The insulation module 300 can be installed at the air inlet of the energy storage box 10. The control module 100 controls the opening area of ​​the insulation module 300 at the air inlet to slow down the rate of temperature change inside the energy storage box 10, thus keeping the temperature of the energy storage device A stable. The heat dissipation module 400 has a blowing function. An air outlet is provided on the other side of the upper box 11 of the energy storage box 10, and the heat dissipation module 400 can be installed at the air outlet. The control module 100 adjusts the air pressure difference between the air inside the energy storage box 10 and the outside air by controlling the airflow of the heat dissipation module 400, thereby adjusting the heat exchange efficiency between the air and the outside and further improving the temperature control effect of the energy storage box 10.

[0035] The technical solution provided by this utility model accurately acquires the temperature data of the energy storage device stored in the energy storage box through a temperature acquisition module. The control module outputs temperature control signals to the insulation module and the heat dissipation module based on the temperature data. The insulation module can adjust the opening area at the air inlet of the energy storage box according to the temperature control signal, thereby slowing down the rate of temperature change in the energy storage box. The heat dissipation module is located at the air outlet of the upper chamber of the energy storage box and can adjust the airflow at the opening of the insulation module according to the temperature control signal, thereby adjusting the pressure difference between the air inside the upper chamber and the outside air pressure, improving the heat dissipation effect of the energy storage box. This achieves efficient control of heat exchange between the air inlet and outlet of the energy storage box and the outside air, further improving the overall temperature control effect of the energy storage box, making the energy storage box compatible with both high and low temperature environments, and reducing the power consumption of the energy storage box for temperature control.

[0036] Optionally, Figure 2 This is a structural schematic diagram of another energy storage box provided according to an embodiment of the present utility model. Based on the above embodiments, see... Figure 2 The insulation module 300 includes an adjustable grille 310; the adjustable grille 310 adjusts its opening degree according to the temperature control signal.

[0037] Specifically, the temperature acquisition module 200 can be a temperature sensor to acquire the temperature of the energy storage device inside the energy storage box 10. The adjustable grille 310 has multiple blades. The control module 100 generates a temperature control signal based on the temperature data. The adjustable grille 310 can control the rotation of the multiple blades according to the temperature control signal, adjusting the opening degree of the blades and changing the opening area at the ventilation opening, thereby slowing down the rate of temperature change inside the energy storage box 10, improving the temperature control effect of the energy storage box 10, and keeping the temperature of the energy storage device A inside the energy storage box 10 stable.

[0038] Optionally, Figure 3 This is a schematic diagram of the adjustable grid structure of an energy storage box according to an embodiment of the present invention. Based on the above embodiment, see... Figure 3 The adjustable grille 310 includes: multiple blades 311, multiple rotating shafts 312, and a motor 313; the multiple blades 311 are connected to the motor 313 via the rotating shafts 312, and the motor 313 is connected to the control module 100; the motor 313 rotates according to the temperature control signal.

[0039] Specifically, each blade 311 is connected to a motor 313 via its own rotating shaft 312, and the motor 313 is connected to the control module 100. The temperature control signal sent by the control module 100 controls the motor 313 to rotate, and the motor 313 drives the rotating shaft 312 to rotate, thereby causing the blade 311 to rotate, adjusting the opening degree of the blade 311, and adjusting the opening area at the vent. For example, when the ambient temperature of the energy storage box 10 is higher than the temperature inside the energy storage box 10, the temperature control signal issued by the control module 100 can cause the blades 311 to rotate by a larger angle, increasing the opening and closing degree of the blades 311. This results in a larger opening area at the ventilation opening of the energy storage box 10, accelerating the efficiency of heat exchange between the air inside the energy storage box 10 and the outside air. When the energy storage box 10 is in a low-temperature environment, the temperature control signal issued by the control module 100 can cause the blades 311 to rotate by a smaller angle, reducing the opening and closing degree of the blades 311. This results in a relatively smaller opening area at the ventilation opening of the energy storage box 10, slowing down the efficiency of heat exchange between the air inside the energy storage box 10 and the outside air, thereby improving the temperature control effect of the energy storage box 10. In other embodiments, the control module 100 can also be located on the surface of the insulation module 300 near the outer side of the energy storage box 10 for easy maintenance by personnel.

[0040] Optionally, based on the above embodiments, see below. Figure 2 The heat dissipation module 400 includes a fan 410; the fan 410 is connected to the control module 100, and the control module 100 adjusts the speed of the fan 410 according to the temperature control signal.

[0041] Specifically, the fan 410 is installed on one side surface of the upper housing 11. The fan 410 can adjust its speed according to the temperature control signal sent by the control module 100, further adjusting the heat exchange efficiency between the air inside the energy storage box 10 and the outside air, thereby improving the temperature control effect of the energy storage box 10. For example, when the ambient temperature of the energy storage box 10 is higher than the temperature inside the energy storage box 10, the temperature control signal issued by the control module 100 can control the fan 410 to increase its speed, increasing the air pressure difference between the energy storage box 10 and the outside. This, combined with the control module 100 controlling the adjustable grille 310 to open a larger opening area, further accelerates the heat exchange efficiency between the air inside the energy storage box 10 and the outside air. When the energy storage box 10 is in a low-temperature environment, the temperature control signal issued by the control module 100 can control the fan 410 to decrease its speed, reducing the air pressure difference between the energy storage box 10 and the outside. This, combined with the control module 100 controlling the adjustable grille 310 to open a smaller opening area or completely close the adjustable grille 310, further reduces the heat exchange efficiency between the air inside the energy storage box 10 and the outside air. This allows the energy storage box 10 to be compatible with both high-temperature and low-temperature environments, while simultaneously reducing the temperature control power consumption of the energy storage box 10. The fan 410 can be an axial flow fan.

[0042] Optionally, based on the above embodiments, see below. Figure 2 The air inlet is located on the first side wall 101 of the upper housing 11, and the air outlet is located on the second side wall 102 of the upper housing 11. The first side wall 101 and the second side wall 102 are arranged opposite to each other.

[0043] Specifically, the first side wall 101 and the second side wall 102 of the upper housing 11 are arranged opposite to each other, and the air inlet and air outlet can be arranged opposite to each other on the first side wall 101 and the second side wall 102 respectively, so that the heat preservation module 300 and the heat dissipation module 400 are arranged opposite to each other to form a straight air duct, reduce airflow resistance, avoid turbulence, further improve the airflow efficiency inside the energy storage box 10, improve the temperature control effect of the energy storage box 10, and reduce the temperature control power consumption of the energy storage box 10.

[0044] Optionally, Figure 4 This is a structural schematic diagram of another energy storage box provided according to an embodiment of the present utility model. Based on the above embodiments, see... Figure 4 The partition 500 partially separates the upper housing 11 and the lower housing 12, which are connected by a connecting area. The lower housing 12 contains an anode electrolyte tank 120 and a cathode electrolyte tank 121. The anode electrolyte tank 120 contains anode electrolyte, and the cathode electrolyte tank 121 contains cathode electrolyte. The anode electrolyte and cathode electrolyte are connected to the energy storage device A through the connecting area.

[0045] Specifically, the energy storage box 10 is partially divided by a partition 500 to form an upper box 11 and a lower box 12, with the unpartitioned portion being the connecting area between the upper box 11 and the lower box 12. The lower box 12 can house an anode electrolyte tank 120 and a cathode electrolyte tank 121. In the connecting area between the upper box 11 and the lower box 12, the anode electrolyte tank 120 and the cathode electrolyte tank 121 can be connected to the energy storage device A via pipelines, allowing the anode electrolyte and cathode electrolyte to be respectively delivered to the energy storage device A for electrolysis.

[0046] Optionally, Figure 5 This is a structural schematic diagram of another energy storage box provided according to an embodiment of the present utility model. Based on the above embodiments, see... Figure 5 The energy storage tank also includes a second temperature acquisition module 600 and a third temperature acquisition module 700; the second temperature acquisition module 600 and the third temperature acquisition module 700 are respectively connected to the control module 100; the second temperature acquisition module 600 is installed in the anode electrolyte tank 120 and is used to acquire the temperature data of the anode electrolyte; the third temperature acquisition module 700 is installed in the cathode electrolyte tank 121 and is used to acquire the temperature data of the cathode electrolyte.

[0047] Specifically, the second temperature acquisition module 600 can be immersed in the anolyte in the anolyte tank 120 to monitor and acquire the temperature data of the anolyte; the third temperature acquisition module 700 can be immersed in the cathode electrolyte in the cathode electrolyte tank 121 to monitor and acquire the temperature data of the cathode electrolyte. The first temperature acquisition module 100, the second temperature acquisition module 600, and the third temperature acquisition module 700 can be temperature sensors. The second temperature acquisition module 600 and the third temperature acquisition module 700 can be connected to the control module 100 via wired or wireless means to transmit the acquired temperature data of the anolyte and the cathode electrolyte to the control module 100 to assist the control module 100 in temperature control.

[0049] Specifically, the first heating module 610 and the second heating module 620 can be thermal resistance wires. The control module 100 is connected to the first heating module 610 and the second heating module 620 respectively, thereby supplying power to the first heating module 610 and the second heating module 620 to generate heat. When the control module 100 determines that the temperature of the anolyte or the cathode electrolyte is low based on the acquired temperature data of the anolyte or the cathode electrolyte, the control module 100 controls the first heating module 610 or the second heating module 620 to operate, thereby heating the anolyte or the cathode electrolyte and ensuring effective electrolyte flow.

[0050] Optionally, based on the above embodiments, see below. Figure 5 The energy storage box also includes an insulation layer 800, which is disposed on the inner wall of the energy storage box and covers the upper box body 11 and the lower box body 12.

[0051] Specifically, the insulation layer 80 covering the upper box 11 and the lower box 12 can prevent the energy storage box from exchanging heat with the outside through the side wall of the box, and further improve the insulation effect of the energy storage box in low temperature environment.
