Description

Technical Field

[0001] This invention relates to the field of energy storage containers, and particularly to an energy storage container for dehumidification. Background Technology

[0002] With the rapid development of energy storage technology, energy storage containers are playing an increasingly important role in energy storage and management. Energy storage containers typically consist of two main parts: a battery compartment for installing energy storage units such as battery packs, and an equipment compartment for installing auxiliary equipment such as battery management systems, temperature control systems, and fire suppression systems. The battery compartment is the core of the energy storage system and requires a stable environment to ensure the safe operation of the battery packs.

[0003] Humidity control in the battery compartment is a key aspect of ensuring the safe and stable operation of energy storage systems. In high-humidity environments, battery packs and internal electronic components are prone to moisture absorption, leading to performance degradation, short circuits, and even safety hazards. For example, excessive humidity may cause condensation on the surface of battery modules, increasing the risk of short circuits and affecting battery safety and lifespan.

[0004] Currently, dehumidification equipment is typically installed directly inside the battery compartment. However, installing dehumidification equipment occupies additional space, thus affecting the energy density within the battery compartment. Furthermore, thermal runaway of the battery pack could impact the dehumidification equipment, posing a safety hazard. Additionally, existing dehumidification equipment is inconvenient to maintain. Summary of the Invention

[0005] The main objective of this invention is to provide an energy storage container that aims to improve at least one of the aforementioned problems.

[0006] To achieve the above objectives, the present invention proposes an energy storage container, comprising: an equipment compartment equipped with a dehumidification system for supplying dehumidified air to the equipment compartment; a battery compartment, wherein the equipment compartment and the battery compartment are isolated from each other; a first channel for fluid communication between the battery compartment and the equipment compartment, allowing dehumidified air to flow from the equipment compartment to the battery compartment; and a second channel for fluid communication between the battery compartment and the equipment compartment, allowing air to flow from the battery compartment to the equipment compartment.

[0007] This invention relates to an energy storage container comprising a dehumidification system, a first channel, and a second channel. The dehumidification system is located within the equipment compartment and supplies dehumidified air to it. The first and second channels extend between the battery compartment and the equipment compartment, enabling fluid communication between their environments. This allows dehumidified air from the equipment compartment to diffuse into the battery compartment via the first channel, and conversely, humid air from the battery compartment to diffuse into the equipment compartment via the second channel. The humid air entering the equipment compartment is then dried by the dehumidification system and reintroduced into the battery compartment, repeating this process to dehumidify the battery compartment. This configuration, placing the dehumidification system within the equipment compartment and only partially utilizing the first and second channels within the battery compartment for air circulation, avoids occupying excessive space within the battery compartment, minimizing the impact on energy density and reducing safety hazards in the event of thermal runaway of the battery pack. Furthermore, the location of the dehumidification system within the equipment compartment facilitates maintenance by operators.

[0008] In one embodiment, the energy storage container further includes an air supply device; the air supply device is used to deliver dehumidified air from the equipment compartment to the battery compartment via the first channel, and deliver air from the battery compartment to the equipment compartment via the second channel.

[0009] In one embodiment, the first channel includes a first air inlet extending into the equipment compartment and a first air outlet extending into the battery compartment and reaching the end of the battery compartment away from the equipment compartment; the second channel includes a second air inlet extending into the battery compartment and a second air outlet extending into the equipment compartment; wherein the first air outlet and the second air inlet are respectively disposed at opposite ends near the battery compartment, such that they are spaced apart from each other.

[0010] In one embodiment, the second air inlet and the first air outlet are disposed inside the battery compartment and located below the top inner surface of the energy storage container.

[0011] In one embodiment, the first air inlet is located near the top inner surface of the energy storage container, and the second air outlet is located near the bottom inner surface of the energy storage container.

[0012] In one embodiment, the second air inlet and the first air outlet are located 400 mm below the top inner surface of the energy storage container.

[0013] In one embodiment, the first channel is formed by a first duct, and the second channel is formed by a second duct.

[0014] In one embodiment, at least one of the equipment compartment or the battery compartment includes the air supply device.

[0015] In one embodiment, the air supply device is at least one of a blower, an exhaust fan, an axial flow fan, a centrifugal fan, and a cross-flow fan.

[0016] In one embodiment, the equipment compartment includes: a drain pipe for discharging water from the energy storage container; and a condensate drain pipe in liquid communication with the dehumidification system and the drain pipe for discharging condensate from the dehumidification system.

[0024] With the rapid development of energy storage technology, energy storage containers are playing an increasingly important role in energy storage and management. Energy storage containers typically consist of two main parts: a battery compartment for installing energy storage units such as battery packs, and an equipment compartment for installing auxiliary equipment such as battery management systems, temperature control systems, and fire suppression systems. The battery compartment is the core of the energy storage system and requires a stable environment to ensure the safe operation of the battery packs.

[0025] Humidity control in the battery compartment is a key aspect of ensuring the safe and stable operation of energy storage systems. In high-humidity environments, battery packs and internal electronic components are prone to moisture absorption, leading to performance degradation, short circuits, and even safety hazards. For example, excessive humidity may cause condensation on the surface of battery modules, increasing the risk of short circuits and affecting battery safety and lifespan.

[0026] Currently, dehumidification equipment is typically installed directly inside the battery compartment. However, installing dehumidification equipment occupies additional space, thus affecting the energy density within the battery compartment. Furthermore, thermal runaway of the battery pack could impact the dehumidification equipment, posing a safety hazard. Additionally, existing dehumidification equipment is inconvenient to maintain.

[0027] Based on this, embodiments of this application provide an energy storage container for dehumidifying the energy storage container, comprising: The equipment compartment is equipped with a dehumidification system that supplies dehumidified air to the equipment compartment; The battery compartment, equipment compartment, and battery compartment are isolated from each other; The first channel enables fluid communication between the battery compartment and the equipment compartment, allowing dehumidified air to flow from the equipment compartment to the battery compartment; and The second channel is used to enable fluid communication between the battery compartment and the equipment compartment, allowing air to flow from the battery compartment to the equipment compartment.

[0028] Furthermore, energy storage containers also include air supply devices; The air supply device is used to deliver dehumidified air from the equipment compartment to the battery compartment via the first channel, and deliver air from the battery compartment to the equipment compartment via the second channel.

[0029] Furthermore, the first channel includes a first air inlet extending into the equipment compartment and a first air outlet extending into the battery compartment and reaching the end of the battery compartment away from the equipment compartment; The second channel includes a second air inlet extending into the battery compartment and a second air outlet extending into the equipment compartment; The first air outlet and the second air inlet are respectively located at opposite ends near the battery compartment, so that they are spaced apart from each other.

[0030] First, it should be noted that in this embodiment, the energy storage container can be applied to the marine industry and supply power to the ship's electric propulsion system. When ships are sailing at sea, the air humidity is usually high, especially in tropical and subtropical waters. Placing the energy storage container on the ship ensures that the batteries inside the container can work better in a suitable humidity environment, thereby reducing equipment damage caused by moisture, reducing the frequency of maintenance and replacement of parts, and lowering maintenance costs. It is understood that the energy storage container can also be applied to other fields.

[0031] Specifically, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the energy storage container includes a container body 1, a dehumidification system 2, and an air supply duct 3. Along the length of the container body 1, an equipment compartment 12 and a battery compartment 11 are sequentially arranged inside the container body 1, meaning the spaces of the equipment compartment 12 and the battery compartment 11 are not connected. For example, a partition is provided inside the container body 1, dividing the space into the battery compartment 11 and the equipment compartment 12, and isolating them. The dehumidification system 2 is located inside the equipment compartment 12 and is used to dehumidify the environment within the equipment compartment 12. The air supply duct 3 includes a first channel 31 and a second channel 32, used to achieve fluid communication between the battery compartment 11 and the equipment compartment 12. For example, in one embodiment, the first channel 31 and the second channel 32 can be formed by corresponding openings on the partition. Alternatively, the first channel 31 and the second channel 32 can also be formed by air ducts extending from the battery compartment 11 into the equipment compartment 12. The air supply duct 3 is located inside the battery compartment 11, and at least a portion of the air supply duct 3 extends from the battery compartment 11 into the equipment compartment 12. Both ends of the air supply duct 3 are open along its length, thereby enabling the environment inside the equipment compartment 12 and the environment inside the battery compartment 11 to be connected via the air supply duct 3. A first air inlet 311 and a second air outlet 322 are formed at the end of the air supply duct 3 that extends into the equipment compartment 12.

[0032] In this embodiment, the battery compartment 11 and the equipment compartment 12 are connected by an air supply duct 3. The air supply duct 3 may include a first channel 31 and a second channel 32. The first channel 31 is the channel corresponding to the first air inlet 311 and the first air outlet 312. That is, the end of the first channel 31 extending into the equipment compartment 12 forms the first air inlet 311, and the end of the first channel 31 extending into the battery compartment 11 forms the first air outlet 312. The second channel 32 is the channel corresponding to the second air inlet 321 and the second air outlet 322. That is, the end of the second channel 32 extending into the battery compartment 11 forms the second air outlet 322, and the end of the second channel 32 extending into the battery compartment 11 forms the second air inlet 321.

[0033] It is understood that the first air outlet 312 is connected to the first air inlet 311 so that air in the equipment compartment 12 enters the battery compartment 11 sequentially through the first air inlet 311 and the first air outlet 312; the second air inlet 321 is connected to the second air outlet 322 so that air in the battery compartment 11 enters the equipment compartment 12 sequentially through the second air inlet 321 and the second air outlet 322.

[0034] Furthermore, the dehumidification system 2 can be kept in a constantly open state, that is, always in a dehumidification state, to ensure that the air environment inside the equipment compartment 12 and the battery compartment 11 is kept in a dry state.

[0035] Among them, the dehumidification system 2 can be a dehumidifier, such as using a refrigeration dehumidification method. Based on the condensation principle, when air passes through the refrigeration system, the temperature decreases, and the water vapor in the air will condense into liquid water, thereby reducing the humidity of the air. Since dehumidifiers are existing technology, and the improvement point of this solution is not in the dehumidification system 2 itself, its structure and working principle will not be described or explained in detail.

[0036] Understandably, placing the dehumidification system 2 inside the equipment compartment 12 is for ease of maintenance. When maintenance or repair is needed, staff only need to open the panel of the equipment compartment 12 to perform the maintenance or repair. If the dehumidification system 2 were placed inside the battery compartment 11, the panel of the battery compartment 11 would also need to be opened. In addition, the battery compartment 11 also contains many high-voltage wiring harnesses. When performing maintenance or repair in the battery compartment 11, due to the limited space and dense equipment, it is easy to make mistakes, resulting in equipment damage or safety accidents, which brings certain inconvenience to the staff. The equipment compartment 12 usually concentrates various control and auxiliary equipment. Placing the dehumidification system 2 inside the equipment compartment 12 can achieve better system integration and centralized management.

[0037] Reference Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment of this application, the energy storage container further includes an air supply device 4, which is used to deliver dehumidified air from the equipment compartment 12 into the battery compartment 11 via the first channel 31, and deliver air from the battery compartment 11 into the equipment compartment 12 via the second channel 32.

[0038] In this embodiment, the air supply device 4 can operate in two modes: a positive pressure mode and a negative pressure mode. In positive pressure mode, the air supply device 4 is located inside the equipment compartment 12 and connected to the first channel 31. It actively forces dehumidified dry air into the battery compartment 11, increasing the air pressure within the battery compartment 11 to create positive pressure. Under this pressure, the humid air returns to the equipment compartment 12 through the second channel 32. In negative pressure mode, the air supply device 4 is located inside the battery compartment 11 and connected to the second channel 32. It actively draws humid air from the battery compartment 11, decreasing the air pressure within the battery compartment 11 to create negative pressure. Under this negative pressure, the dry air in the equipment compartment 12 is drawn into the battery compartment 11 through the first channel 31. Both operating modes can create continuous air circulation between the battery compartment 11 and the equipment compartment 12, achieving uniform dehumidification. The appropriate mode can be selected based on the actual installation space and maintenance requirements.

[0039] Specifically, the air supply device 4 is used to send dry air from the equipment compartment 12 into the battery compartment 11 through the first air inlet 311 and the first channel 31. As the dry air continuously enters the battery compartment 11, the air pressure inside the battery compartment 11 increases, thereby forcing the original humid air in the battery compartment 11 to be forced into the second channel 32 and discharged into the equipment compartment 12 through the second channel 32 and the second air outlet 322 in sequence. The humid air discharged from the battery compartment 11 is dehumidified by the dehumidification system 2. The above process is continuously cyclical, thereby realizing the exchange of dry air in the equipment compartment 12 and humid air in the battery compartment 11. Under the action of the air supply device 4, the dry air is evenly distributed in the battery compartment 11, avoiding the situation of excessive or low local humidity and improving the dehumidification effect.

[0040] It is understandable that the battery compartment 11 and the equipment compartment 12 are both sealed environments, and they are connected by the air supply duct 3. The air supply device 4 exchanges the dry air in the equipment compartment 12 with the humid air in the battery compartment 11. That is, the dry air in the equipment compartment 12 is sent into the battery compartment 11, while the humid air in the battery compartment 11 is drawn back into the equipment compartment 12 for dehumidification, forming a closed loop. This achieves the effect of dehumidifying and drying the environment inside the battery compartment 11. Due to the presence of the air supply device 4, the dry air in the equipment compartment 12 can be distributed as evenly as possible in the battery compartment 11, thereby improving the dehumidification effect of the environment inside the battery compartment 11 and avoiding situations where the local humidity is too low or too high.

[0041] Optionally, the air supply device 4 can also be installed inside the battery compartment 11. When installed inside the battery compartment 11, the air supply device 4 should be installed on the first channel 31 and draw dry air from the equipment compartment 12 into the first channel 31 through the first air inlet 311, and then send it into the battery compartment 11 through the first air outlet 312.

[0042] Optionally, the air supply device 4 can be installed in the equipment compartment 12 and the battery compartment 11 respectively, that is, there can be two air supply devices 4. By installing two sets of air supply devices 4, the suction efficiency of airflow can be improved, thereby improving the air exchange efficiency between the equipment compartment 12 and the battery compartment 11.

[0043] In this embodiment, regardless of whether the air supply device 4 is located in the equipment compartment 12, the battery compartment 11, or both, the air supply direction of the air supply device 4 can be adjusted to achieve gas circulation and convection. For example, the air supply device 4 draws the humid air in the battery compartment 11 into the equipment compartment 12 through the first channel 31 (second channel 32), thereby increasing the air pressure in the equipment compartment 12 and forcing the dry air in the equipment compartment 12 into the battery compartment 11 through the second channel 32 (first channel 31). This achieves circulation between the humid air in the battery compartment 11 and the relatively dry air in the equipment compartment 12, and dries the environment inside the battery compartment 11.

[0044] Optionally, the air supply device 4 is at least one of a blower, an axial flow fan, a centrifugal fan, and a cross-flow fan. In specific implementation, the appropriate fan type can be selected according to different needs. In specific implementation, the air supply direction of the fan can be adjusted to achieve the circulation and convection of the air with higher humidity in the battery compartment 11 and the dry air in the equipment compartment 12, so as to achieve the drying treatment of the environment in the battery compartment 11.

[0045] Optionally, a humidity sensor can be installed in the battery compartment 11 to monitor the air humidity in the battery compartment 11 in real time. The humidity sensor, dehumidification system 2 and air supply device 4 are all communicatively connected to a controller. The controller is used to receive the signal from the humidity sensor and control the operation of dehumidification system 2 and air supply device 4 according to the preset humidity range. When the humidity in the battery compartment 11 returns to the preset range, the control system will automatically stop the operation of dehumidification system 2 and air supply device 4.

[0046] It should be noted that, in order to avoid unnecessary dehumidification operations due to false alarms from a single humidity sensor, a redundant design can be adopted, that is, multiple humidity sensors can be set up for cross-verification. For example, multiple humidity sensors can be arranged and evenly distributed in various areas within the battery compartment 11, thereby improving the accuracy of monitoring the air humidity within the battery compartment 11. The control system will only start the dehumidification system 2 and the air supply device 4 when at least two humidity sensors simultaneously detect that the humidity exceeds the preset range. And when all humidity sensors detect that the humidity has returned to the preset range, the control system will automatically stop the operation of the dehumidification system 2 and the air supply device 4. Through the redundant design, malfunctions caused by false alarms from a single sensor are avoided, and the reliability of the system is improved.

[0047] Optionally, a humidity sensor (communicating with the controller) can be installed in the equipment compartment 12 to monitor the air humidity in the equipment compartment 12 in real time. If the air humidity in the equipment compartment 12 exceeds the preset range, and the air humidity in the battery compartment 11 is within the preset range, the controller will only control the dehumidification system 2 to start to dehumidify the air environment in the equipment compartment 12. If the air humidity in the battery compartment 11 also exceeds the preset range, the controller will control the air supply device 4 to start to dehumidify the air environment in the battery compartment 11.

[0048] Reference Figure 4 As shown, in one embodiment of this application, in the length direction of the battery compartment 11, a first air outlet 312 is provided at one end of the battery compartment 11 near the equipment compartment 12, so that dry air in the equipment compartment 12 enters the battery compartment 11 through the first air outlet 312, and a second air inlet 321 is provided at one end of the battery compartment 11 away from the equipment compartment 12, so that humid air in the battery compartment 11 enters the equipment compartment 12 through the second air inlet 321.

[0049] In this embodiment, the first air outlet 312 and the second air inlet 321 are spaced apart and respectively located at opposite ends of the battery compartment 11. After entering the battery compartment 11 through the first air inlet 311, the dry air flows away from the equipment compartment 12 along the airflow path. As the dry air flows along the length of the battery compartment 11, it gradually absorbs moisture from within the battery compartment 11. The humid air within the battery compartment 11 is also propelled away from the equipment compartment 12 by the dry air and is ultimately drawn back into the equipment compartment 12 through the second air inlet 321 for drying. This arrangement of the first air outlet 312 and the second air inlet 321 ensures that the dry air is evenly distributed throughout the battery compartment 11, preventing excessively high or low humidity in certain areas and improving the dehumidification effect within the battery compartment 11, thus achieving uniform dehumidification. Without uniform dehumidification, some areas of the battery compartment 11 may not be effectively dehumidified, potentially affecting the operation of the battery pack 5.

[0050] In this embodiment, the first air outlet 312 can also be located at the end of the battery compartment 11 away from the equipment compartment 12, so that dry air in the equipment compartment 12 can enter the battery compartment 11 through the first air outlet 312. The second air inlet 321 is located at the end of the battery compartment 11 close to the equipment compartment 12, so that humid air in the battery compartment 11 can enter the equipment compartment 12 through the second air inlet 321. With the above arrangement, the air in the battery compartment 11 and the equipment compartment 12 can also be circulated and dehumidified.

[0051] Reference Figure 3 , Figure 4As shown, in one embodiment of this application, the second air inlet 321 and the first air outlet 312 are disposed inside the battery compartment 11 and located below the top inner surface of the energy storage container. Specifically, a hazardous gas accumulation zone 13 is formed on the top of the battery compartment 11; in the height direction of the battery compartment 11, both the second air inlet 321 and the first air outlet 312 are located below the hazardous gas accumulation zone 13.

[0052] First, it should be noted that, in the vertical direction of the battery compartment 11, a hazardous gas accumulation zone 13 is formed within 400mm of the inner top wall of the battery compartment 11 from top to bottom; in the vertical direction of the battery compartment 11, the distance between the second air inlet 321 and the first air outlet 312 and the inner top wall of the battery compartment 11 is greater than 400mm, for example, it can be 500mm or other values. That is, the second air inlet 321 and the first air outlet 312 are located outside the 400mm range below the top inner surface of the energy storage container.

[0053] In this embodiment, while dehumidifying the environment inside the battery compartment 11, safety issues are fully considered. When the battery pack 5 inside the battery compartment 11 experiences thermal runaway, a large amount of hazardous gas will be generated, and the hazardous gas is mainly hydrogen. Since hydrogen has a low density, it will accumulate at the top of the battery compartment 11, thereby forming a hazardous gas accumulation area 13 in a certain space at the top of the battery compartment 11.

[0054] In this embodiment, to prevent hazardous gases accumulated in the hazardous gas accumulation area 13 at the top of the battery compartment 11 from entering the equipment compartment 12 during the exchange of dry and humid air between the equipment compartment 12 and the battery compartment 11, the first air outlet 312 and the second air inlet 321 are both located away from the hazardous gas accumulation area 13. That is, along the height direction, the first air outlet 312 and the second air inlet 321 are both located below the hazardous gas accumulation area. Figure 4 As shown, for example, it can be located in the middle or bottom of the battery compartment 11, that is, away from the hazardous gas accumulation area 13, so as to avoid the hazardous gas in the hazardous gas accumulation area 13 at the top of the battery compartment 11 from entering the equipment compartment 12 with the movement of the airflow.

[0055] Reference Figure 4 , Figure 7 As shown, in one embodiment of this application, the openings of the first air outlet 312 and the second air inlet 321 are both arranged downwards in the height direction of the energy storage container. In this embodiment, the opening of the first air outlet 312 is set downwards so that when the dry air enters the battery compartment 11, it flows from top to bottom, which can effectively prevent dangerous gases (such as hydrogen) at the top of the battery compartment 11 from being drawn into the airflow, and further improve the safety of the system.

[0056] In this embodiment, the opening of the second air inlet 321 is also set downwards, thereby ensuring that the humid air in the battery compartment 11 is drawn back into the equipment compartment 12 from below, so as to prevent dangerous gases such as hydrogen from being entrained in the airflow and thus avoid entering the equipment compartment 12, ensuring the safety of the system.

[0057] In this embodiment, the opening orientation of the first air outlet 312 and the second air inlet 321 can also be arranged in a horizontal direction, so that the dry air flows in a horizontal direction when it enters the battery compartment 11, which can also prevent dangerous gases (such as hydrogen) on the top of the battery compartment 11 from being drawn into the airflow.

[0058] In this embodiment, the opening orientation of the first air outlet 312 and the second air inlet 321 can also be between the two directions mentioned above. For example, the openings of the first air outlet 312 and the second air inlet 321 are both arranged downwards, referred to as the first direction, and the openings of the first air outlet 312 and the second air inlet 321 are arranged horizontally, referred to as the second direction. By setting the opening orientation of the first air outlet 312 and the second air inlet 321 between the first direction and the second direction, the dry air flows between the first direction and the second direction when it enters the battery compartment 11. This can also prevent dangerous gases (such as hydrogen) at the top of the battery compartment 11 from being entrained in the airflow, thereby improving the safety of the system.

[0059] In one embodiment of this application, the first air inlet 311 is close to the top inner surface of the energy storage container, and the second air outlet 322 is close to the bottom inner surface of the energy storage container.

[0060] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 As shown, in one embodiment of this application, the air supply duct 3 includes a first channel 31 and a second channel 32; wherein, the first channel 31 is disposed in the battery compartment 11, and the first channel 31 extends at least partially from the battery compartment 11 into the equipment compartment 12, and a first air inlet 311 is formed at the end of the first channel 31 extending into the equipment compartment 12, and a first air outlet 312 is formed at the end of the first channel 31 located in the battery compartment 11; the second channel 32 is disposed in the battery compartment 11, and the second channel 32 extends at least partially from the battery compartment 11 into the equipment compartment 12, and a second air outlet 322 is formed at the end of the second channel 32 extending into the equipment compartment 12, and a second air inlet 321 is formed at the end of the second channel 32 located in the battery compartment 11.

[0061] Specifically, one end of the first channel 31 extends into the equipment compartment 12 to form a first air inlet 311; the other end of the first channel 31 extends into the battery compartment 11 to form a first air outlet 312.

[0062] One end of the second channel 32 extends into the battery compartment 11 to form a second air inlet 321; the other end of the second channel 32 extends into the equipment compartment 12 to form a second air outlet 322.

[0063] In this embodiment, the first channel 31 extends into the equipment compartment 12 at one end to form a first air inlet 311, and the second channel 32 extends into the equipment compartment 12 at one end to form a second air outlet 322. To prevent the humid air discharged from the second air outlet 322 from being sent back into the battery compartment 11 by the air supply device 4 from the first air inlet 311 before being dehumidified by the dehumidification system 2, the first air inlet 311 and the second air outlet 322 are arranged at intervals in the equipment compartment 12. For example, the first air inlet 311 is set in the upper area of ​​the equipment compartment 12, and the second air outlet 322 is set in the lower area of ​​the equipment compartment 12. This ensures that the humid air can be fully dried by the dehumidification system 2 after entering the equipment compartment 12, thereby preventing the humid air from being sent into the battery compartment 11 without being dried, thus improving the dehumidification effect.

[0064] In this embodiment, multiple first air inlets 311 and first air outlets 312 formed at both ends of the length direction of the first channel 31 can be provided, and multiple second air inlets 321 and second air outlets 322 formed at both ends of the length direction of the second channel 32 can also be provided. This can further improve the uniformity of dry air entering the battery compartment 11 from the first air outlet 312, so that the dry gas can be diffused simultaneously from multiple areas in the battery compartment 11; at the same time, the humid air in the battery compartment 11 can enter the second channel 32 from multiple areas through the second air inlet 321, which can significantly improve the air exchange efficiency.

[0065] In one embodiment, the first channel 31 is formed by a first air duct, and the second channel 32 is formed by a second air duct.

[0066] Reference Figure 5 , Figure 6 As shown in one embodiment of this application, the equipment compartment 12 has a drainage pipe 121 connected to the outside, and the condensate drain pipe 21 of the dehumidification system 2 is connected to the drainage pipe 121. During operation, the dehumidification system 2 will generate condensate, which needs to be properly treated to avoid water accumulation in the equipment compartment 12 and potential safety hazards. The condensate drain pipe 21 of the dehumidification system 2 is connected to the drainage pipe 121 in the equipment compartment 12 to ensure that the condensate can be smoothly discharged from the equipment compartment 12 and finally discharged to the outside.

[0067] In this embodiment, the drain pipe 121 should be located at the bottom of the equipment compartment 12 to ensure that condensate can be discharged smoothly. In this embodiment, a solenoid valve for controlling the opening and closing of the drain pipe 121 is provided on the drain pipe 121, and the solenoid valve is communicatively connected to the controller. The drain pipe 121 is also provided with a liquid level sensor (communically connected to the controller) for detecting the liquid level inside it. The liquid level sensor has a first threshold for issuing an alarm and a second threshold for de-alarming. When the amount of water in the drain pipe 121 exceeds the first threshold, the liquid level sensor is triggered and sends a command to the controller to control the solenoid valve to open, so as to discharge the condensate generated when the dehumidification system 2 is working. When the amount of water in the drain pipe 121 is lower than the second threshold, the liquid level sensor de-alarms, and the controller controls the solenoid valve to close. This achieves the goal of opening the solenoid valve when drainage is needed and closing the solenoid valve when drainage is not needed, so as to ensure the airtightness of the energy storage container.

[0068] In this embodiment, a liquid storage area can be provided in the equipment compartment 12. The liquid storage area is used to store the condensate generated when the dehumidification system 2 is working. That is, the condensate drain pipe 21 of the dehumidification system 2 is connected to the above-mentioned liquid storage area. When the dehumidification system 2 is working, the condensate generated is directly discharged into the above-mentioned liquid storage area through the condensate drain pipe 21 for temporary storage. The staff regularly cleans the liquid storage area and then moves the stored condensate out of the equipment compartment 12 to keep the equipment compartment 12 dry and clean.

[0069] In this embodiment, the condensate is centrally stored in the liquid storage area, which facilitates regular cleaning by staff and reduces the frequency and complexity of maintenance. For example, the liquid storage area can be a box or a bottle. The design of the box or bottle should be easy to clean, and staff can periodically open the panel of the equipment compartment 12 and open the box or bottle to discharge the condensate stored inside.
