Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] The following is combined with Figures 1 to 2The present invention will be described in detail with specific embodiments of the liquid-cooled battery compartment 200 and the energy storage container. The energy storage container includes a container body 100 and a liquid-cooled battery compartment 200. The liquid-cooled battery compartment 200 is installed inside the container body 100 and includes a battery rack 210 and a liquid cooling assembly. The battery rack 210 provides an installation compartment for the battery pack 300 inside the container body 100. The liquid cooling assembly cools the battery pack 300 through liquid cooling pipes 221 fixed to the battery rack 210, thereby providing a safe and stable operating temperature environment for the battery pack 300 and ensuring the normal charging and discharging of the energy storage container.

[0036] The existing liquid-cooled battery compartment 200 poses a safety risk of electrical short circuit due to leakage in the liquid-cooled piping 221 during use. To address this issue, refer to... Figure 2 As shown, the liquid-cooled battery compartment 200 provided in this embodiment also includes a leakage sensing component 230. The leakage sensing component 230 is installed on the liquid-cooled pipeline 221 to detect whether there is leakage in the liquid-cooled pipeline 221. The staff can make timely feedback based on the real-time information sent by the leakage sensing component 230, thereby solving the problem that leakage in the liquid-cooled pipeline 221 cannot be detected and dealt with in a timely manner in the prior art. This effectively improves the detection sensitivity of whether leakage occurs in the liquid-cooled pipeline 221 and ensures the safety and reliability of the liquid-cooled pipeline 221.

[0037] Specifically, the leakage sensing component 230 includes a leakage sensor 231 and a connecting harness 232, wherein the leakage sensor 231 is disposed on the liquid cooling pipeline 221; the liquid-cooled battery compartment 200 provided in this embodiment also includes a battery management system 240, which is fixedly mounted on the battery rack 210, and the leakage sensor 231 is signal-connected to the battery management system 240 through the connecting harness 232. Because the leakage sensor 231 is small in size and highly sensitive, it can be stably installed in high-density energy storage containers, and the electrodes of the leakage sensor 231 are usually made of metallic materials (such as copper, aluminum, etc.), giving the leakage sensor 231 good conductivity. When a leak occurs in the liquid cooling pipe 221, water will flow out and come into contact with the electrodes on the leak sensor 231, thus effectively detecting the change in water conductivity. The leak sensor 231 will convert this change into an electrical signal through its internal circuitry, and then transmit the electrical signal to the battery management system 240 through the connecting harness 232. If a leak is detected, the battery management system 240 will issue a warning signal, thereby effectively improving the safety of the liquid-cooled battery compartment 200.

[0038] More specifically, such as Figure 1As shown, the liquid-cooled battery compartment 200 provided in this embodiment is also equipped with a display screen 260 on the outside of the door 250. The display screen 260 is connected to the battery management system 240 via a cable to facilitate staff to inspect at any time.

[0039] Specifically, in this embodiment, the liquid-cooled battery compartment 200 is positioned along a predetermined horizontal direction (e.g., ...). Figure 1 Multiple battery racks 210 are arranged side by side (in the direction indicated by the arrow), and cooling channels for liquid flow are provided on the wall of the mounting compartment of the battery rack 210. In addition, the liquid cooling pipeline 221 provided in this embodiment also includes a main inlet pipe 2211, a main outlet pipe 2212, a plurality of inlet branch pipes 2213 and a plurality of outlet branch pipes 2214 connected in sequence. One end of the main inlet pipe 2211 is connected to the plurality of inlet branch pipes 2213 and the other end is connected to the drain port of the condenser. One end of the main outlet pipe 2212 is connected to the plurality of outlet branch pipes 2212 and the other end is connected to the liquid inlet of the condenser. The extension directions of the main outlet pipe 2212 and the main inlet pipe 2211 are both parallel to the horizontal preset direction. The inlet branch pipes 2213 and the outlet branch pipes 2214 are each correspondingly arranged on the battery rack 210. The inlet branch pipes 2213 are connected to the liquid inlet of the cooling channel and the outlet branch pipes 2214 are connected to the liquid outlet of the cooling channel. With the above configuration, the liquid cooling pipeline 221 can simultaneously cool and reduce the temperature of the battery packs 300 on multiple battery racks 210. The structure is compact and the layout is reasonable, which effectively ensures the reliability of the energy storage container.

[0040] More specifically, in this embodiment, as Figure 2 As shown, the battery rack 210 has multiple installation compartments arranged vertically, so that one battery rack 210 can simultaneously support multiple battery packs 300, thereby increasing the energy density of the energy storage container. In addition, the water inlet branch pipe 2213 provided in this embodiment also includes a water inlet branch pipe body and multiple branch liquid inlet pipes. The water inlet branch pipe body extends vertically, and the branch liquid inlet pipes are correspondingly installed in the installation compartments. One end of the water inlet branch pipe body is connected to the main water inlet pipe 2211, and the other end is connected to the corresponding liquid inlet through the branch liquid inlet pipe. The water outlet branch pipe 2214 includes a water outlet branch pipe body and multiple branch liquid outlet pipes. The water outlet branch pipe body extends vertically, and the branch liquid outlet pipes are correspondingly installed in the installation compartments. One end of the water outlet branch pipe body is connected to the main water outlet pipe 2212, and the other end is connected to the corresponding liquid outlet through the branch liquid outlet pipe. With the above settings, the inflow and outflow of cooling water to each battery pack 300 on a single battery rack 210 can be controlled, thereby ensuring the balance of cooling water flowing between each battery pack 300. This ensures that the temperature of each battery pack 300 is stable during charging and discharging, greatly improving the stability and reliability of the energy storage container.

[0041] Furthermore, in this embodiment, the radial dimension of the inlet branch pipe body is smaller than the radial dimension of the inlet main pipe 2211, and the radial dimension of the outlet branch pipe body is smaller than the radial dimension of the outlet main pipe 2212. By reducing the size of the inlet branch pipe body and the outlet branch pipe body, the flow rate and volume of the cooling water entering the inlet branch pipe body can be increased, and the flow velocity of the working fluid in the outlet branch pipe body can also be increased, thereby effectively accelerating the cooling efficiency of the liquid cooling component for the battery pack 300. Especially when the energy storage container is under high load operation, the cooling effect on the battery pack 300 is more obvious.

[0042] Because the radial dimensions of the inlet and outlet branch pipes are relatively small and the water flow velocity is relatively fast, while the diameters of the main inlet pipe 2211 and the main outlet pipe 2212 are larger and the water flow velocity is relatively slow, it is easy for pipe ruptures to occur in the inlet and outlet branch pipes, leading to water leakage. Therefore, in this embodiment, a leakage sensor 231 is installed on both the inlet and outlet branch pipes. This allows for the determination of the integrity of the liquid cooling pipeline 221 simply by detecting the presence of leaks in the inlet and outlet branch pipes, thereby saving on operating costs.

[0043] Of course, in other embodiments, in order to meet the customer's demand for high safety and stability in the use of the energy storage container, the above-mentioned leakage sensor 231 can also be set on the main water inlet pipe 2211 and the main water outlet pipe 2212; or a leakage sensor 231 can be set at certain intervals on the main body of the main water inlet branch pipe and the main body of the main water outlet branch pipe, thereby expanding the detection range of the liquid cooling pipeline 221 and further improving the leakage detection sensitivity of the leakage sensing component 230 to the liquid cooling pipeline 221.

[0044] Specifically, the liquid-cooled battery compartment 200 provided in this embodiment also includes a control valve 270. The control valve 270 is installed on the main water inlet pipe 2211 so that when the leakage sensing component 230 detects leakage information, the staff can prevent water from continuing to enter the main water inlet pipe body through the control valve 270, so as to facilitate the staff to inspect and replace the main water inlet pipe body.

[0045] Furthermore, in this embodiment, a control valve 270 is also provided on the water outlet main pipe 2212 so that the liquid-cooled battery compartment 200 can adjust the flow rate and speed of the cooling water entering the cooling channel by adjusting the opening of the control valve 270 on the water inlet main pipe 2211 and the water outlet main pipe 2212, so as to maintain the balance and stability of the working environment temperature of the battery pack 300.

[0046] Preferably, the control valve 270 is a solenoid valve and is electrically connected to the leakage sensor 231, so that the control valve 270 can receive the signal from the leakage sensor 231 in real time. When the leakage sensor 231 detects leakage, it will send a signal to the control valve 270 to automatically adjust the valve opening, thereby avoiding manual intervention and improving response efficiency.

[0047] This embodiment also provides an energy storage container, which includes a container body 100 and a liquid-cooled battery compartment 200. By installing the liquid-cooled battery compartment 200 provided in this embodiment inside the container body 100, the energy storage container can absorb the heat generated by the battery pack 300 inside the container body 100 during charging and discharging operations, thereby cooling the battery pack 300 and ensuring that the battery pack 300 is always within a suitable temperature range. At the same time, the leakage sensing component 230 installed on the liquid cooling pipeline 221 can improve the detection sensitivity of the energy storage container to whether there is a leakage in the liquid cooling pipeline 221, so as to ensure that the staff can detect the leakage in time and complete the repair and replacement of the liquid cooling pipeline 221, thereby improving the safety of the energy storage container during use.
