Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, specifically to energy storage containers. Background Technology

[0002] Energy storage containers contain battery packs for storing electrical energy and electrical equipment for controlling the batteries. To address the need for dehumidification after opening the doors for maintenance in hot and humid weather, dehumidifiers are typically installed on the containers to ensure a dry working environment for the battery packs. Most existing dehumidifiers are installed on the battery compartment doors, with both recessed and protruding designs.

[0003] However, dehumidifiers are relatively large. For embedded dehumidifiers, they take up a lot of space inside the container. In order to achieve high energy density, the remaining space inside the battery compartment of current energy storage containers is very limited, and there is not enough space to install dehumidifiers. If dehumidifiers are installed in the battery compartment, it will reduce the energy density of the container. For dehumidifiers that protrude out of the container, they take up too much space outside the container, which may cause the container to be too wide, affecting transportation and affecting the appearance of the product. Utility Model Content

[0004] In view of this, the present invention provides an energy storage container to solve the problems of dehumidifiers occupying too much space in the battery compartment, thus reducing the energy density of the energy storage container, or protruding too much outside the container, thus affecting aesthetics and transportation.

[0005] This utility model provides an energy storage container, comprising: a container body having a battery compartment and an electrical compartment spaced apart, wherein a battery pack is disposed in the battery compartment and electrical equipment is disposed in the electrical compartment; an exhaust structure adapted to connect the battery compartment and the electrical compartment to extract gas from the battery compartment to the electrical compartment; an exhaust structure adapted to connect the battery compartment and the electrical compartment to allow gas in the electrical compartment to flow to the battery compartment; and a dehumidification structure disposed in the electrical compartment.

[0006] Beneficial effects: By setting up an exhaust and return structure suitable for connecting the battery compartment and the electrical compartment, a gas circulation loop is formed between the battery compartment and the electrical compartment. The gas in the battery compartment is extracted to the electrical compartment by the exhaust structure, dehumidified and dried by the dehumidification structure in the electrical compartment, and then flows back to the battery compartment through the return structure. This achieves gas circulation between the battery compartment and the electrical compartment, thereby dehumidifying and drying the gas in the battery compartment. Furthermore, by placing the dehumidification structure in the electrical compartment, which is separated from the battery compartment, the dehumidification structure makes full use of the space in the electrical compartment. This avoids the dehumidification structure occupying the internal space of the battery compartment, thus ensuring the energy storage container has high energy efficiency. At the same time, the dehumidification structure is located inside the container, avoiding excessive protrusion outside the container, which would affect aesthetics and transportation.

[0007] In one optional embodiment, the battery compartment is adjacent to the electrical compartment, and the battery compartment and the electrical compartment are separated by a first partition wall, the first partition wall having a ventilation opening; the exhaust structure includes a ventilation fan, the ventilation fan being disposed in the electrical compartment and communicating with the battery compartment through the ventilation opening.

[0008] Beneficial effects: By opening a vent in the first partition wall between the battery compartment and the electrical compartment, and installing an air exchange fan in the electrical compartment that is connected to the battery compartment through the vent, the air in the battery compartment can be drawn into the electrical compartment through the vent, thus achieving air flow. The vent has a simple structure, is easy to manufacture, and the air exchange fan is relatively common and low in cost. It can also accelerate the air flow speed, thereby improving dehumidification efficiency.

[0009] In one optional embodiment, the air extraction structure further includes an air extraction pipe disposed in the battery compartment, with the air inlet of the air extraction pipe facing the internal opening of the battery compartment and the air outlet of the air extraction pipe connected to the vent.

[0010] Beneficial effects: By installing an exhaust pipe connected to the vent in the battery compartment, with the intake port of the exhaust pipe located in the battery compartment away from the vent, the gas in the battery compartment away from the vent can be introduced into the electrical compartment through the exhaust pipe and the vent. This avoids the situation where only the gas near the vent is circulated, increases the gas circulation range, and ensures that the gas in the battery compartment away from the vent can also enter the electrical compartment for dehumidification, further ensuring the dehumidification effect of the gas in the battery compartment.

[0011] In one optional embodiment, the air extraction pipe is provided with a plurality of air inlets, the air inlets penetrating the pipe wall of the air extraction pipe.

[0012] And / or, the exhaust pipe is located at the top of the battery compartment, and the ventilation fan is located at the top of the electrical compartment;

[0013] And / or, the extraction structure further includes a check valve connected between the ventilation fan and the extraction pipeline to prevent gas from flowing back from the electrical compartment to the battery compartment.

[0014] Beneficial effects: By opening an air inlet hole through the pipe wall in the exhaust pipe, the gas near the pipe wall can enter the exhaust pipe through the air inlet hole, and then be drawn to the electrical compartment for dehumidification by the ventilation fan. This increases the air intake of the exhaust pipe, expands the gas circulation path, and increases the coverage of the recirculating gas, thereby improving the dehumidification efficiency.

[0015] The top of the battery compartment is not easily affected by components such as battery packs, and the top of the electrical compartment is not easily affected by electrical equipment. The top has relatively ample space for installation, which facilitates the arrangement of exhaust pipes and ventilation fans, and also facilitates later maintenance and replacement operations.

[0016] By installing a check valve between the ventilation fan and the exhaust pipe, the gas can only flow in one direction from the exhaust pipe to the ventilation fan, preventing backflow and improving safety. Furthermore, it prevents undehumidified gas from flowing back into the battery compartment, further ensuring effective dehumidification.

[0017] In one alternative embodiment, the electrical compartment is further provided with a cooling structure adapted to cool the gas in the electrical compartment.

[0018] Beneficial effects: By installing a cooling structure in the electrical compartment, the gas in the electrical compartment can be cooled down, thereby cooling down the electrical equipment in the electrical compartment, preventing the electrical equipment from overheating, ensuring the safe operation of the electrical equipment, and thus improving the safety of the energy storage container.

[0019] In one alternative implementation, the dehumidification structure is integrated with the cooling structure as an air conditioner.

[0020] Beneficial effects: The air conditioner integrates the dehumidification and cooling structures into one unit. It has both dehumidification and cooling functions. It can be used to dehumidify the air introduced from the battery compartment into the electrical compartment, and to cool down the electrical equipment in the electrical compartment. By integrating the two structures into one unit, there is no need to set up a separate dehumidifier, which takes up less space and can also reduce costs.

[0021] In one optional embodiment, a return air vent is provided on the first partition wall, and the return air structure is disposed on the first partition wall and corresponding to the return air vent. The return air structure is adapted to control the opening and closing of the return air vent.

[0022] Beneficial effects: By opening a return air vent in the first partition wall, which serves as a return air channel between the battery compartment and the electrical compartment, and by setting the return air structure on the first partition wall and corresponding to the return air vent, the opening and closing of the return air vent can be controlled through the return air structure. This allows for control of the opening and closing of the return air channel between the electrical compartment and the battery compartment, which helps to ensure the smooth flow of the gas circulation loop during the dehumidification of the battery compartment and to reduce the mutual influence between the two compartments when dehumidification of the battery compartment is not required.

[0023] In one alternative implementation, the air return structure is an electrically operated louvered structure.

[0024] Beneficial effects: easy to control, highly automated, and the louvered structure is easy to open, takes up little space when open, and is easy to set up.

[0025] In one optional implementation, the energy storage container further includes:

[0026] A humidity detection unit is disposed in the battery compartment to detect the humidity in the battery compartment;

[0027] And / or, a gas detection unit, which is installed at the air outlet of the ventilation fan, to detect the concentration of combustible gas in the gas at the air outlet of the ventilation fan;

[0028] And / or, a temperature detection unit, which is disposed in the electrical compartment to detect the temperature in the electrical compartment.

[0029] Beneficial effects: By installing a humidity detection unit in the battery compartment, the humidity in the battery compartment can be detected in real time and accurately. This allows for the selection of whether to dehumidify the air in the battery compartment based on the humidity level, avoiding the impact on battery pack performance due to untimely dehumidification, or the waste of resources caused by activating the dehumidification structure when dehumidification is not needed.

[0030] By installing a gas detection unit at the air outlet of the ventilation fan to detect the concentration of combustible gases, the concentration of combustible gases in the battery compartment can be detected. This facilitates timely handling when the concentration of combustible gases in the battery compartment exceeds the standard, thereby improving safety.

[0031] By installing a temperature detection unit in the electrical compartment to monitor the temperature inside, it is possible to determine whether the temperature of the electrical equipment is too high during operation. This allows for the selection of whether to cool the equipment based on whether the temperature is too high, thereby further ensuring the safe operation of the equipment.

[0032] In one optional embodiment, the energy storage container further includes: a controller, which is electrically connected to the ventilation fan, the electric louver structure, the dehumidification structure, the cooling structure, the humidity detection unit, and the temperature detection unit; the controller controls the start and stop of the ventilation fan and the dehumidification structure, as well as the opening and closing of the electric louver structure, based on the humidity detected by the humidity detection unit in the battery compartment; the controller controls the start and stop of the cooling structure based on the temperature detected by the temperature detection unit in the electrical compartment.

[0033] Beneficial effects: By setting the controller to control whether the dehumidification function is turned on based on the humidity in the battery compartment detected by the humidity detection unit, and to control whether the cooling function is turned on based on the temperature in the electrical compartment detected by the temperature detection unit, the system achieves automated control with fast response and high accuracy, ensuring the timely activation of the dehumidification or cooling functions, avoiding resource waste and saving costs.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. 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.

[0043] Traditional energy storage containers typically dehumidify the battery compartment by installing dehumidifiers on the door of the battery compartment. For a 20-foot container, the dehumidifier's dehumidification capacity is generally above 10L / D (i.e., 10 liters / day). The dehumidifier is large and occupies a lot of space, leaving very limited space inside the battery compartment, which cannot meet the installation requirements. Furthermore, the protruding installation of the dehumidifier affects the product's aesthetics and may cause the container to exceed the width limit, affecting transportation. In addition, the dehumidifier adds extra cost to the overall system.

[0044] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.

[0045] According to an embodiment of the present invention, an energy storage container is provided, comprising: a container body 1, an extraction structure 2, a return structure 3, and a dehumidification structure. The container body 1 has a battery compartment 101 and an electrical compartment 102 spaced apart. The battery compartment 101 contains a battery pack, and the electrical compartment 102 contains electrical equipment. The extraction structure 2 is adapted to connect the battery compartment 101 and the electrical compartment 102 to extract gas from the battery compartment 101 to the electrical compartment 102. The return structure 3 is adapted to connect the battery compartment 101 and the electrical compartment 102 to allow gas in the electrical compartment 102 to flow to the battery compartment 101. The dehumidification structure is disposed within the electrical compartment 102.

[0046] By using the energy storage container of this embodiment, an extraction structure 2 and a return structure 3 are set up to connect the battery compartment 101 and the electrical compartment 102, so that a gas circulation loop is formed between the battery compartment 101 and the electrical compartment 102. The gas in the battery compartment 101 is extracted to the electrical compartment 102 by the extraction structure 2, and after being dehumidified and dried by the dehumidification structure in the electrical compartment 102, it flows back to the battery compartment 101 through the return structure 3, realizing the circulation of gas between the battery compartment 101 and the electrical compartment 102, thereby achieving the dehumidification and drying of the gas in the battery compartment 101. Furthermore, by setting the dehumidification structure in the electrical compartment 102, which is separated from the battery compartment 101, the dehumidification structure makes full use of the space in the electrical compartment 102. This avoids the dehumidification structure occupying the internal space of the battery compartment 101, thus ensuring that the energy storage container has high energy efficiency. At the same time, the dehumidification structure is located inside the container, avoiding the dehumidification structure protruding too much outside the container, which would affect the aesthetics and transportation.

[0047] The exhaust structure 2 and the return structure 3 are located at different positions within the housing 1, i.e., they are spaced apart, to ensure that a complete gas circulation loop is formed between the battery compartment 101 and the electrical compartment 102 through the connection of the exhaust structure 2 and the return structure 3.

[0048] It should be noted that the battery pack in the battery compartment 101 is used to store electrical energy, and the electrical equipment in the electrical compartment 102 includes power distribution cabinets, etc. The electrical equipment is electrically connected to the battery pack and is used to control the battery.

[0049] In one embodiment, such as Figure 1 and Figure 3 As shown, the battery compartment 101 is adjacent to the electrical compartment 102, and the battery compartment 101 and the electrical compartment 102 are separated by a first partition wall 110, on which a ventilation opening 111 is provided. The exhaust structure 2 includes a ventilation fan 201, which is installed in the electrical compartment 102 and connected to the battery compartment 101 through the ventilation opening 111. By providing a ventilation opening 111 in the first partition wall 110 between the battery compartment 101 and the electrical compartment 102, and by providing a ventilation fan 201 located in the electrical compartment 102 and connected to the battery compartment 101 through the ventilation opening 111, the air in the battery compartment 101 can be drawn into the electrical compartment 102 through the ventilation opening 111, thus achieving air flow. The ventilation opening 111 has a simple structure and is easy to manufacture, while the ventilation fan 201 is common and low in cost. It can also accelerate the air flow speed, thereby improving dehumidification efficiency.

[0050] In one embodiment, such as Figure 1 and Figure 3As shown, the exhaust structure 2 also includes an exhaust pipe 202, which is disposed in the battery compartment 101. The air inlet 2021 of the exhaust pipe 202 faces the interior opening of the battery compartment 101, and the air outlet of the exhaust pipe 202 is connected to the vent 111. By providing an exhaust pipe 202 connected to the vent 111 in the battery compartment 101, and with the air inlet 2021 of the exhaust pipe 202 located in the battery compartment 101 away from the vent 111, the gas in the battery compartment 101 away from the vent 111 can be introduced into the electrical compartment 102 through the exhaust pipe 202 and the vent 111. This avoids the situation where only the gas near the vent 111 circulates, increases the gas circulation range, and ensures that the gas in the battery compartment 101 away from the vent 111 can also enter the electrical compartment 102 for dehumidification, further ensuring the dehumidification effect of the gas in the battery compartment 101.

[0051] Preferably, the air inlet 2021 of the exhaust pipe 202 is located near the wall of the battery compartment 101 opposite to the first partition wall 110, so that the air inlet 2021 is as far away from the vent 111 as possible, thereby maximizing the gas circulation range and ensuring that gas at a position far from the vent 111 can also be extracted into the electrical compartment 102, further improving the dehumidification effect.

[0052] In one embodiment, such as Figure 1 As shown, the exhaust pipe 202 has several air inlets 2022, which penetrate the pipe wall of the exhaust pipe 202. By opening air inlets 2022 that penetrate the pipe wall of the exhaust pipe 202, gas near the pipe wall of the exhaust pipe 202 can enter the exhaust pipe 202 through the air inlets 2022, and then be drawn to the electrical compartment 102 by the ventilation fan 201 for dehumidification. This increases the air intake of the exhaust pipe 202, expands the gas circulation path, and increases the coverage of the recirculating gas, thereby improving the dehumidification efficiency.

[0053] Preferably, such as Figure 1 As shown, a plurality of air inlets 2022 are spaced apart along the extension direction of the exhaust pipe 202, ensuring that gas at different locations within the battery compartment 101 along the extension direction of the exhaust pipe 202 can enter the electrical compartment 102 through the exhaust pipe 202 to participate in gas circulation, further improving dehumidification efficiency. More preferably, the plurality of air inlets 2022 are equally spaced along the extension direction of the exhaust pipe 202.

[0054] In one embodiment, the exhaust pipe 202 is a straight pipe, with one end serving as an air inlet port 2021 and the other end as an air outlet port. It is understood that, as an alternative implementation, the exhaust pipe 202 can also be a bent pipe to maximize contact with the gas inside the battery compartment 101. Multiple exhaust pipes 202 can also be connected, with their outlet ports converging into a single outlet that connects to the vent 111.

[0055] In one embodiment, such as Figure 1 As shown, the exhaust pipe 202 is located at the top of the battery compartment 101, and the ventilation fan 201 is located at the top of the electrical compartment 102. Correspondingly, the vent 111 is located on the first partition wall 110 near the top of the housing 1. It should be noted that "top" refers to... Figure 1 The area indicated by the middle arrow is in the direction of "up". The battery compartment 101 mainly houses the battery pack and high-voltage box, fire protection pipes and heat exchange pipes, etc. The electrical compartment 102 mainly houses the power distribution junction box, fire controller and other electrical equipment. The top of the battery compartment 101 is not easily affected by the battery pack and other components, and the top of the electrical compartment 102 is not easily affected by the electrical equipment. The top has relatively ample space for the arrangement of the exhaust pipe 202 and the ventilation fan 201, and also facilitates future maintenance and replacement operations.

[0056] In one embodiment, such as Figure 2 As shown, the exhaust structure 2 also includes a check valve 203, which is connected between the ventilation fan 201 and the exhaust pipe 202 to prevent gas from flowing back from the electrical compartment 102 into the battery compartment 101. By installing the check valve 203 between the ventilation fan 201 and the exhaust pipe 202, a unidirectional flow of gas is ensured, allowing gas to flow only from the exhaust pipe 202 to the ventilation fan 201, thus preventing backflow and improving safety. Furthermore, preventing undehumidified gas from flowing back into the battery compartment 101 further ensures effective dehumidification.

[0057] In one embodiment, a cooling structure is also provided inside the electrical compartment 102, which is suitable for cooling the gas in the electrical compartment 102. It should be noted that the electrical equipment in the electrical compartment 102 generates heat during operation. If prolonged heating leads to excessively high temperatures, it will damage the equipment, shorten its service life, and high-temperature operation poses significant risks. Therefore, by providing a cooling structure in the electrical compartment 102, the gas in the electrical compartment 102 can be cooled down, thereby cooling down the electrical equipment in the electrical compartment 102, preventing excessive temperature rise of the electrical equipment, ensuring the safe operation of the electrical equipment, and thus improving the safety of the energy storage container.

[0058] In one embodiment, the dehumidification structure and the cooling structure are integrated into an air conditioner 4. The dehumidification structure and the cooling structure are integrated into a single air conditioner 4, which has both dehumidification and cooling functions. It can be used to dehumidify the gas introduced into the electrical compartment 102 from the battery compartment 101, and to cool down the electrical equipment in the electrical compartment 102. By integrating the two structures into one unit, there is no need to set up a separate dehumidifier, which occupies less space and can also reduce costs.

[0059] In other embodiments, the dehumidification structure may not be integrated with the cooling structure, and the dehumidification structure may be a separate dehumidifier.

[0060] In one embodiment, such as Figure 1 As shown, a return air vent is provided on the first partition wall 110, and a return air structure 3 is set on the first partition wall 110 and corresponding to the return air vent. The return air structure 3 is adapted to control the opening and closing of the return air vent. By providing a return air vent on the first partition wall 110, the return air vent serves as a return air channel between the battery compartment 101 and the electrical compartment 102. By setting the return air structure 3 on the first partition wall 110 and corresponding to the return air vent, the opening and closing of the return air vent can be controlled, thereby controlling the opening and closing of the return air channel between the electrical compartment 102 and the battery compartment 101. This helps to ensure the smooth flow of the gas circulation loop during the dehumidification of the battery compartment 101 and to reduce the mutual influence between the two compartments when dehumidification of the battery compartment 101 is not required.

[0061] Preferably, the return air vent is located on the first partition wall 110 near the bottom of the housing 1, wherein the bottom of the housing 1 refers to the upper edge of the housing 1. Figure 1 The part indicated by the middle arrow pointing "down" is located at the top of the housing 1. The exhaust structure 2 is located near the bottom of the housing 1, meaning that the two are located relatively far apart in the vertical direction. This ensures sufficient circulation of gas in the battery compartment 101 and the electrical compartment 102, avoiding the phenomenon of only local gas circulation due to the exhaust structure 2 and the return structure 3 being too close together. This ensures sufficient dehumidification of the gas in the battery compartment 101 and enhances the dehumidification effect.

[0062] In one embodiment, the return air structure 3 is an electrically operated louvered structure. This facilitates control, provides a high degree of automation, and the louvered structure is easy to open, occupies minimal space when open, and is convenient to install.

[0063] In other embodiments, the return air structure 3 can also be a fan-type or push-pull type structure, which can also achieve the control of opening and closing of the return air vent.

[0064] In one embodiment, such as Figure 1As shown, the energy storage container also includes a humidity detection unit 5, which is installed in the battery compartment 101 to detect the humidity in the battery compartment 101. By installing the humidity detection unit 5 in the battery compartment 101, the humidity in the battery compartment 101 can be detected accurately in real time. This allows for selection of whether to dehumidify the air in the battery compartment 101 based on the humidity level, avoiding untimely dehumidification that could affect battery pack performance, or activating the dehumidification structure when dehumidification is not needed, thus preventing resource waste. It should be noted that the location of the humidity detection unit 5 is not limited to the top of the container 1; it can also be installed along the sides. Figure 1 The "up and down direction" indicated by the middle arrow is located in the middle of box 1.

[0065] In one embodiment, the battery compartment 101 is further provided with a battery temperature detection structure to detect the temperature of the battery pack. When the battery pack temperature is too high, the battery pack is cooled down to improve the safety of the battery pack.

[0066] In one embodiment, the humidity detection unit 5 is integrated with the battery temperature detection structure into a single temperature and humidity sensor, which has a simple structure and facilitates the layout of related circuits.

[0067] In one embodiment, such as Figure 2 As shown, the energy storage container also includes a gas detection unit 6, which is installed at the outlet of the ventilation fan 201 to detect the concentration of combustible gas in the gas at the outlet of the ventilation fan 201. It should be noted that the gas at the outlet of the ventilation fan 201 is drawn from the battery compartment 101. By installing the gas detection unit 6 at the outlet of the ventilation fan 201 to detect the concentration of combustible gas, the concentration of combustible gas in the battery compartment 101 can be detected, facilitating timely handling when the concentration of combustible gas in the battery compartment 101 exceeds the standard, thereby improving safety.

[0068] Specifically, the gas detection unit 6 is electrically connected to the controller. When the gas detection unit 6 detects an abnormal concentration of VOC (Volatile Organic Compounds), it uploads an alarm to the BMS (Battery Management System) to realize the return air gas monitoring function.

[0069] In one embodiment, the gas detection unit 6 is a composite detector that can effectively detect the concentration of combustible materials and has high reliability.

[0070] In one embodiment, the energy storage container further includes a temperature detection unit disposed in the electrical compartment 102 to detect the temperature within the electrical compartment 102. It should be noted that the electrical equipment is disposed in the electrical compartment 102; when the temperature of the electrical equipment rises, the temperature in the electrical compartment 102 also rises. By using a temperature detection unit in the electrical compartment 102 to detect the temperature, it is possible to determine whether the temperature of the electrical equipment is too high during operation. This allows for the selection of whether to cool the equipment based on whether overheating is present, further ensuring the safe operation of the equipment.

[0071] In one embodiment, the temperature detection unit is a temperature sensor, which has a simple structure, low cost, and high sensitivity.

[0072] In one embodiment, the energy storage container further includes a controller, which is electrically connected to the ventilation fan 201, the electric louver structure, the dehumidification structure, the cooling structure, the humidity detection unit 5, and the temperature detection unit. The controller controls the start and stop of the ventilation fan 201 and the dehumidification structure, as well as the opening and closing of the electric louver structure, based on the humidity detected by the humidity detection unit 5 in the battery compartment 101. The controller also controls the start and stop of the cooling structure based on the temperature detected by the temperature detection unit in the electrical compartment 102. By setting the controller to control whether the dehumidification function is activated based on the humidity detected by the humidity detection unit 5 in the battery compartment 101, and to control whether the cooling function is activated based on the temperature detected by the temperature detection unit in the electrical compartment 102, automated control is achieved. This results in fast response, high accuracy, and timely activation of the dehumidification or cooling functions, while also avoiding resource waste and saving costs.

[0073] Specifically, when the humidity detection unit 5 detects that the humidity in the battery compartment 101 exceeds the standard, it transmits a relevant signal to the controller. The controller then activates the ventilation fan 201 and the electric louver structure to form an air circulation loop between the battery compartment 101 and the electrical compartment 102, and simultaneously activates the dehumidification structure for dehumidification. However, when the humidity detection unit 5 detects that the humidity in the battery compartment 101 returns to normal, it transmits a relevant signal to the controller, which then shuts down the ventilation fan 201, the electric louver structure, and the dehumidification structure, ceasing dehumidification. When the temperature detection unit detects that the temperature in the electrical compartment 102 exceeds the standard, it transmits a relevant signal to the controller. The controller then activates the cooling structure to cool the electrical compartment 102, thereby cooling the electrical equipment within it. When the temperature detection unit detects that the temperature in the electrical compartment 102 returns to normal, the controller shuts down the cooling structure, ceasing cooling, which helps save energy and reduce costs.

[0074] In the case where the dehumidification and cooling structures are integrated into an air conditioner, the controller is directly electrically connected to the air conditioner. When the humidity detection unit 5 detects that the humidity in the battery compartment 101 exceeds the standard, the controller controls the air conditioner 4 to turn on the dehumidification function. When the humidity detection unit 5 detects that the humidity in the battery compartment 101 returns to normal, the controller controls the air conditioner 4 to turn off the dehumidification function. When the temperature detection unit detects that the temperature in the electrical compartment 102 exceeds the standard, the controller controls the air conditioner 4 to turn on the cooling function. When the temperature detection unit detects that the temperature in the electrical compartment 102 returns to normal, the controller controls the air conditioner 4 to turn off the cooling function.

[0075] In one embodiment, such as Figure 1 and Figure 3 As shown, a heat exchange chamber 103 is also formed inside the housing 1. The heat exchange chamber 103 is spaced apart from the battery compartment 101 and the electrical compartment 102. A heat exchange unit is installed in the heat exchange chamber 103, and heat exchange pipelines are installed in the battery compartment 101. The heat exchange unit is adapted to exchange heat with the heat exchange pipelines. The heat exchange pipelines in the battery compartment 101 are adapted to exchange heat with the battery pack. The heat exchange pipelines carry heat to the heat exchange chamber 103 to exchange heat with the heat exchange unit, thereby cooling down the battery pack and improving the safety of the battery pack.

[0076] Specifically, the enclosure 1 also has a second partition wall 120, which, together with the first partition wall 110, forms a "T" shape to divide the interior of the enclosure 1 into three compartments. The battery compartment 101 is located on one side of the first partition wall 110, while the electrical compartment 102 and the heat exchange compartment 103 are located on the other side of the first partition wall 110. The electrical compartment 102 and the heat exchange compartment 103 are separated by the second partition wall 120. Different components are installed in the battery compartment 101, the electrical compartment 102, and the heat exchange compartment 103 to reduce mutual interference between components in different compartments.

[0077] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
