This application provides an energy storage container to improve space utilization of a battery compartment, to improve energy storage effect. The energy storage container of the described invention is defined in independent claim <NUM> and its dependent claims.

An embodiment of this application provides an energy storage container, including a box body. The box body includes a function compartment and a battery compartment. The function compartment may include a power distribution room and a controller room, and the function compartment and the battery compartment are sequentially distributed in a length direction of the box body. In this arrangement manner, the function compartment and the battery compartment are provided at two ends of the box body. That is, the battery compartment may be a compartment body that is continuously distributed. When a battery rack for installing a battery pack is disposed in the battery compartment, space in the battery compartment may be fully utilized. A quantity of battery racks disposed in the battery compartment is increased, thus increasing a quantity of battery packs in the battery compartment, thereby further improving space utilization and integration of the energy storage container. In addition, the power distribution room and the controller room are separately provided, and are both provided at an end of the box body, so as to facilitate subsequent maintenance.

It should be noted that, to improve working safety of the energy storage container, a protective layer featuring a fireproof function and a heat preservation function may be provided between the battery compartment and the function compartment.

In a possible embodiment, the controller room and the power distribution room may be provided in a plurality of forms. For example, in a height direction of the box body, the controller room may be located above the power distribution room, and the controller room may be provided with an air outlet on a side wall in a width direction of the box body. The controller room may be provided with an air inlet on a side wall in the length direction of the box body. The air inlet and the air outlet form a heat dissipation channel. Air enters the controller room through the air inlet and is discharged to outside of the controller room through the air outlet, to perform ventilation and heat dissipation on a control device in the controller room.

The controller room may be provided with one or two air inlets on the side wall in the length direction of the box body. When there are two air inlets, the two air inlets may be respectively provided on two side walls of the controller room in the length direction of the box body.

It should be noted that, to improve working stability of the control device in the controller room, a protective apparatus may be provided at the air inlet. The protective apparatus is configured to prevent dust and rainwater from entering the controller room through the air inlet. In addition, in a specific implementation process, the protective apparatus may be provided at both the air inlet and the air outlet. The protective apparatus may be disposed to reduce a probability that the dust and the rainwater enter the controller room through the air inlet and the air outlet, thereby improving the working stability of the control device in the controller room, and further improving service life of the control device in the controller room.

In a possible embodiment, the controller room may further include a plurality of groups of mounting bracket assemblies, and two adjacent groups of the mounting bracket assemblies are disposed at intervals in the width direction of the box body. Each of the groups of the mounting bracket assemblies includes a plurality of mounting bracket assemblies disposed in a height direction of the box body. Each of the mounting bracket assemblies is configured to mount the control device, and the control device can be connected to the battery pack in the battery compartment, to control the battery pack in the battery compartment.

When each of the groups of the mounting bracket assemblies includes the plurality of mounting bracket assemblies disposed in the height direction of the box body, the mounting bracket assembly may include a fixed part and a sliding part. The fixed part is fastened to a side wall of the controller room facing a side of the battery compartment, and the fixed part may further include an extension part. The extension part extends away from the side wall of the controller room facing the side of the battery compartment, and the extension part may have a slide rail. An extension direction of the slide rail is the same as the length direction of the box body. The sliding part may include a slide groove that matches the slide rail. The control device may be connected to the slide groove, or a bearing part is provided on the slide groove, and the control device may be disposed on the bearing part. When the control device is specifically detected or operated, the control device may be directly pulled out from the mounting bracket assembly (similar to a drawer) at the air outlet, to improve convenience of operation or detection.

It should be noted that, the mounting bracket assembly in each of the groups of the mounting bracket assemblies may be distributed in a same manner as the battery pack in the battery compartment. In this way, when the control device mounted in each of the mounting bracket assemblies is connected to the battery pack corresponding to the control device, a length of a connection line is relatively short, thereby reducing the length of the connection line.

In a possible embodiment, in the height direction of the box body, when the controller room is located above the power distribution room, the controller room may include the plurality of mounting bracket assemblies, and the plurality of mounting bracket assemblies may be disposed at intervals in the width direction of the box body. In this case, the mounting bracket assembly includes the fixed part and the sliding part. The fixed part may include a mounting bracket. An end of the mounting bracket is fastened to the side wall of the controller room facing the side of the battery compartment. The mounting bracket extends toward a side away from the side wall, and the mounting bracket is provided with an accommodating cavity. The accommodating cavity may accommodate the sliding part. A bottom of the accommodating cavity is provided with the slide rail. The slide rail extends in the length direction of the box body and is perpendicular to the side wall of the controller room facing the side of the battery compartment. The sliding part includes the slide groove that matches the slide rail. The slide groove may be directly connected to the control device, or the bearing part is disposed on the slide groove, and the control device is disposed on the bearing part. In this manner, the control device is disposed in the height direction of the box body. When the control device is specifically detected or operated, because the control device may slide in the accommodating cavity of the mounting bracket, the control device may be directly pulled out from the mounting bracket assembly (similar to the drawer) at the air outlet, to improve the convenience of operating or detecting the control device.

In a possible embodiment, the power distribution room also needs to be provided with a heat dissipation apparatus, to enable a device in the power distribution room to work stably. Specifically, when the power distribution room is provided below the controller room, the power distribution room may be provided with a side-open door on the side wall in the width direction of the box body, and the heat dissipation apparatus may be disposed on the side-open door. The heat dissipation apparatus may be an air conditioner. There may be one or two side-open doors. In addition, when there are two side-open doors, one of the two side-open doors is provided with the heat dissipation apparatus, and the other of the two side-open doors may be provided with an observation window. When it is ensured that the device in the power distribution room can work stably, an interior of the power distribution room may be further observed through the observation window.

In a possible embodiment, the power distribution room and the controller room may also be provided in parallel in the width direction of the box body. The controller room is provided with the air outlet on the side wall in the width direction of the box body, the controller room is provided with the air inlet on the side wall in the length direction of the box body, and the air inlet and the air outlet form the heat dissipation channel. The power distribution room is provided with the side-open door on the side wall in the length direction of the box body, and the side-open door is provided with the heat dissipation apparatus. In this arrangement manner, the air outlet and the air inlet provided on the controller room may still form the heat dissipation channel, so that the air enters the controller room to dissipate heat for the control device disposed in the controller room. The side-open door of the power distribution room is provided on the side wall in the length direction of the box body, to avoid the air outlet.

When the power distribution room and the controller room are provided in parallel in the width direction of the box body, the plurality of mounting bracket assemblies disposed in the controller room may be disposed at intervals in the height direction of the box body, and each of the mounting bracket assemblies may include the fixed part and the sliding part. The fixed part may include slide rails disposed on the two side walls of the controller room in the length direction of the box body. The two slide rails are symmetrically arranged, and the slide rail extends in the width direction of the box body. The sliding part may include the slide groove disposed on the control device, and the slide groove can match the slide rail, so that the control device can slide in the width direction of the box body, so as to facilitate the operation or detection of the control device.

In the foregoing embodiment, the battery compartment may include a plurality of accommodating spaces used to accommodate the battery rack. The plurality of accommodating spaces may be provided at intervals in the length direction of the box body. In addition, in the length direction of the box body, every two adjacent accommodating spaces are communicated. Each of the accommodating spaces is provided with a side door on the side wall in the length direction of the box body. Specifically, in the width direction, two battery racks may be provided in each of the accommodating spaces, a bottom wall of each of the accommodating spaces is provided with the slide rail, and the slide groove that matches the slide rail is disposed below the battery rack. In this way, the battery rack can be conveniently installed in the accommodating space. When the battery rack in the accommodating space and the battery pack disposed on the battery rack need to be maintained, side doors on two sides of the accommodating space can be directly opened to maintain the battery rack in the accommodating space and the battery pack disposed on the battery rack. In this way, a technical person does not need to enter the battery compartment, and thus a channel for overhaul and maintenance may not be disposed in the battery compartment, thereby improving the space utilization inside the energy storage container and improving a capacity of energy storage.

With rapid development of an energy storage device, an energy storage container is used in an increasingly wide range. The energy storage container is a highly integrated energy storage apparatus, a plurality of energy storage battery packs are placed in the energy storage container, and the energy storage container is connected to an external device through a few interfaces. The energy storage container features high integration, a small footprint, and good expansibility. The energy storage container is an important part for development of distributed energy, a smart grid, and energy internet in an energy storage system. However, in the conventional technology, some functional zones of the energy storage container are disposed in the middle of a box body. Space for placing the energy storage battery pack is separated, which may cause a decrease in space utilization of the energy storage container.

As shown in <FIG>, an energy storage container provided in an embodiment of this application includes a box body. The box body includes a function compartment <NUM> and a battery compartment <NUM> that are sequentially distributed in a length direction of the box body. The function compartment <NUM> includes a power distribution room <NUM> and a controller room <NUM>. In this arrangement manner, the function compartment <NUM> and the battery compartment <NUM> are disposed at two ends of the box body, and the battery compartment <NUM> is a continuous and uninterrupted compartment. When a battery rack is disposed in the battery compartment <NUM>, space in the battery compartment <NUM> can be fully used, which enables the battery rack to be properly distributed in the battery compartment <NUM>, increases a quantity of battery racks in the battery compartment <NUM>, and enables the battery compartment <NUM> to install more battery packs, to improve space utilization and integration of the energy storage container. In addition, the power distribution room <NUM> and the controller room <NUM> are provided at a same end of the box body, and the power distribution room <NUM> and the controller room <NUM> are separately provided, to facilitate subsequent maintenance.

It should be noted that, to improve strength of a side wall of the power distribution room <NUM> in the length direction of the box body, the side wall of the power distribution room <NUM> in the length direction of the box body can be prepared by using a corrugated plate.

In a possible embodiment, <FIG> is a three-dimensional diagram of a structure corresponding to the energy storage container in <FIG> is a plan view of the structure observed in a direction A in <FIG>. It should be understood that, to show a specific structure of the controller room, structures at an air inlet <NUM> and an air outlet <NUM> are different. As shown in <FIG>, the controller room <NUM> and the power distribution room <NUM> may be provided in a plurality of forms at the end of the box body. For example, in the function compartment and in a height direction of the box body, the controller room <NUM> can be provided above the power distribution room <NUM>. An area of the controller room <NUM> and an area of the power distribution room <NUM> may be the same. That is, the function compartment is equally divided by the controller room <NUM> and the power distribution room <NUM>. Alternatively, the area of the controller room <NUM> is greater than the area of the power distribution room <NUM>. Alternatively, the area of the controller room <NUM> is less than the area of the power distribution room <NUM>. This is not specifically limited herein. Regardless how the area of the controller room <NUM> and the area of the power distribution room <NUM> are allocated in the function compartment, the controller room <NUM> is provided with the air outlet <NUM> on a side wall in a width direction of the box body, and the controller room <NUM> is provided with the air inlet <NUM> on the side wall in the length direction of the box body. The air inlet <NUM> and the air outlet <NUM> cooperate to form a heat dissipation channel, and air can enter the controller room <NUM> through the air inlet <NUM>. When the air in the controller room <NUM> passes through a control device <NUM> in the controller room <NUM>, the air may take away heat generated by the control device <NUM>, and is discharged from the air outlet <NUM>, so that the control device <NUM> in the controller room <NUM> can work stably.

In a specific implementation process, a plurality of groups of mounting bracket assemblies <NUM> can be disposed in the controller room <NUM>. Each of the groups of the mounting bracket assemblies <NUM> includes a plurality of mounting bracket assemblies <NUM> disposed in the height direction of the box body, and two adjacent groups of the mounting bracket assemblies <NUM> are disposed at intervals in the width direction of the box body. Each of the mounting bracket assemblies <NUM> is configured to mount the control device <NUM>. Specifically, there may be two groups of the mounting bracket assemblies <NUM>. The two groups of the mounting bracket assemblies <NUM> correspond to the battery packs disposed on the battery racks in the battery compartment <NUM>. In the length direction of the box body, the control device <NUM> on each of the mounting bracket assemblies <NUM> can correspond to a battery on the battery rack, so that when the control device <NUM> is connected to the battery pack, a connection line can be directly connected to the control device <NUM> through a side wall of the battery compartment <NUM> facing the controller room <NUM>, thereby reducing a length of the connection line, improving simplicity of the controller room <NUM>, and facilitating operation.

Each of the groups of the mounting bracket assemblies <NUM> can include three mounting bracket assemblies <NUM> arranged at intervals in the height direction of the box body. Each of the mounting bracket assemblies <NUM> in the two groups of the mounting bracket assemblies is arranged in a one-to-one correspondence.

When each of the groups of the mounting bracket assemblies <NUM> includes the plurality of mounting bracket assemblies <NUM> disposed in the height direction of the box body, to improve convenience of mounting the control device <NUM> in the controller room <NUM> and convenience of detection, the mounting bracket assembly <NUM> may include a fixed part and a sliding part. An end of the fixed part may be fastened to the side wall of the controller room <NUM> facing a side of the battery compartment <NUM>, and the fixed part may be provided with an extension part extending to a side away from the battery compartment <NUM>. A slide rail may be disposed on a side that is of the extension part and that faces away from the power distribution room <NUM>. The sliding part may include a slide groove that matches the slide rail and a bearing part that is connected to the slide groove and that is used to bear the control device <NUM>. During specific arrangement, the extension part may be perpendicular to the side wall of the controller room <NUM> facing the side of the battery compartment <NUM>, and parallel to a bottom wall of the controller room <NUM>. In a direction of the slide rail that is disposed on the extension part and that moves away from the side wall of the controller room <NUM> facing the side of the battery compartment <NUM>, a distance between the slide rail and the bottom wall of the controller room <NUM> gradually increases. In this way, when the sliding part bears the control device <NUM> to slide close to the side wall of the controller room <NUM> facing the side of the battery compartment <NUM>, the sliding part can be stabilized in such position, thereby improving working stability of the control device <NUM>.

In addition, the slide rail disposed on the extension part may also extend in the width direction of the box body, and there may be two slide rails. The two slide rails are disposed in parallel, and the slide groove that is disposed on the bearing part and that matches the slide rail is also disposed in the width direction of the box body. In this case, overhaul and maintenance may be performed on the control device <NUM> at the air inlet <NUM>.

It should be noted that the bearing part and the control device <NUM> may be integrated. A specific structure of the mounting bracket assembly <NUM> may also be in other forms, which are not enumerated herein.

In addition, <FIG> is still another three-dimensional diagram of a structure of the energy storage container in <FIG> is a plan view of a structure observed in a direction B in <FIG>. It should be understood that, to show the specific structure of the controller room, the structures at the air inlet <NUM> and the air outlet <NUM> are different. <FIG> is a plan view of a structure observed in a direction C in <FIG>. As shown in <FIG>, in the function compartment and in the height direction of the box body, when the controller room <NUM> is provided above the power distribution room <NUM>, the mounting bracket assemblies <NUM> disposed in the controller room <NUM> may also be disposed at intervals in the width direction of the box body. In this case, there is a specific gap between a top of each of the mounting bracket assemblies <NUM> and a top wall of the controller room <NUM>, so that the air passing through the air inlet <NUM> can enter between two adjacent mounting bracket assemblies <NUM> through the gap, to take away the heat generated by the control device <NUM> disposed on the mounting bracket assembly <NUM>, and be discharged from the air outlet <NUM>, so as to ensure that each control device <NUM> can run stably.

When the plurality of mounting bracket assemblies <NUM> are arranged at intervals in the width direction of the box body, to improve the convenience of mounting the control device <NUM> in the controller room <NUM> and the convenience of detection, the mounting bracket assembly <NUM> may include the fixed part and the sliding part. The fixed part may be a mounting bracket of which an end is fastened to the side wall of the controller room <NUM> facing the side of the battery compartment <NUM>, and the mounting bracket extends to the side away from the side wall. An accommodating cavity for accommodating the sliding part is provided on the mounting bracket. The accommodating cavity has an opening on the side away from the side wall. A bottom of the accommodating cavity is provided with the slide rail. An extension direction of the slide rail is the same as the length direction of the box body. The slide rail is perpendicular to the side wall. During specific arrangement, the sliding part is provided with the slide groove that matches the slide rail. An end of the slide groove away from the slide rail may be directly connected to the control device <NUM>. Alternatively, the bearing part for mounting the control device <NUM> is provided at an end of the slide groove away from the slide rail. In this way, the control device is mounted in the mounting bracket assembly, and the control device <NUM> can further slide in the length direction of the box body in the mounting bracket. To improve stability of the control device <NUM> mounted on the mounting bracket assembly <NUM>, in the direction of the slide rail that is disposed on the bottom of the accommodating cavity and that moves away from the side wall of the controller room <NUM> facing the side of the battery compartment <NUM>, the distance between the slide rail and the bottom wall of the controller room <NUM> gradually increases. In this way, the control device <NUM> slides in the length direction of the box body until a rail faces the side wall of the controller room <NUM> facing the side of the battery compartment <NUM>, to enable the control device <NUM> to be stabilized in such position.

In addition, during specific arrangement of the mounting bracket, the mounting bracket may be perpendicular to the side wall of the controller room <NUM> facing the side of the battery compartment <NUM>, and the mounting bracket is disposed in parallel with the side wall in the length direction of the box body. The slide rail is also perpendicular to the side wall of the controller room <NUM> facing the side of the battery compartment <NUM>, and the mounting bracket is disposed in parallel with the side wall in the length direction of the box body. In this way, the bearing part matching the slide rail and the control device <NUM> mounted at the bearing part are perpendicular to the side wall of the controller room <NUM> facing the side of the battery compartment <NUM>, and are disposed in parallel with the side wall in the length direction of the box body, to reduce space occupied by the control device <NUM> in the accommodating cavity, thereby reducing space occupied by the mounting bracket in the controller room <NUM>.

It should be noted that, when the air inlet <NUM> is specifically provided in the controller room <NUM>, the controller room <NUM> may be provided with the air inlet <NUM> on a side wall in the length direction of the box body, and the air inlet <NUM> may correspond to the mounting bracket assembly <NUM> in the controller room <NUM>, to ensure heat dissipation effect of the control device <NUM> on the mounting bracket assembly <NUM>. In addition, there may also be a plurality of air inlets <NUM> provided on the side wall of the controller room <NUM> in the length direction of the box body. The plurality of air inlets <NUM> may be a plurality of openings provided on the side wall. The air may enter the controller room <NUM> through the plurality of air inlets <NUM> to dissipate heat for the control device <NUM>. The air inlet <NUM> may also be provided on two side walls of the controller room <NUM> in the length direction of the box body. Two air inlets <NUM> may be symmetrically provided, and both the two air inlets <NUM> may correspond to the mounting bracket assembly <NUM> disposed in the controller room <NUM>. Alternatively, one of the two air inlets <NUM> corresponds to the mounting bracket assembly <NUM> disposed in the controller room <NUM>, and the other of the two air inlets <NUM> is the plurality of openings disposed on the other side wall. In this case, the air outlet <NUM> provided on the side wall of the controller room <NUM> in the width direction of the box body may be an opening corresponding to the plurality of mounting bracket assemblies, or may be the plurality of openings disposed on the side wall. The air inlet <NUM> and the air outlet <NUM> may be provided in a plurality of forms, which are not enumerated herein.

<FIG> is a three-dimensional diagram of a structure corresponding to the energy storage container in <FIG>. As shown in <FIG>, in the function compartment and in the height direction of the box body, when the controller room <NUM> is provided above the power distribution room <NUM>, to improve a protection level of the controller room <NUM>, a protective apparatus <NUM> may be disposed at the air outlet. The protective apparatus <NUM> may be disposed to reduce impurities entering the controller room <NUM> from the air outlet, and improve dust-proof, sand-proof, and waterproof capabilities of the controller room <NUM>. In addition, when the protective apparatus <NUM> is disposed at the air outlet, the protective apparatus <NUM> may also be disposed at the air inlet. In this case, the protective apparatus <NUM> is disposed at both the air inlet and the air outlet, and the protection level of the controller room <NUM> may reach IP21, leading to stronger dust-proof, sand-proof, and waterproof capabilities of the controller room <NUM>. The protective apparatus may be a window blind.

In the foregoing embodiment, as shown in <FIG>, a side-open door <NUM> may be disposed on the side wall of the power distribution room <NUM> in the width direction of the box body, and a heat dissipation apparatus <NUM> may be disposed on the side-open door <NUM>. The protection level of the power distribution room <NUM> is IP55 (ingress protection, protection level). A first digit indicates a level of dust-proof and foreign object intrusion prevention of an electric appliance (the foreign object referred to herein, such as a tool and a finger of a person, cannot touch a charged portion of the electric appliance, so as to avoid electric shock). A second digit indicates a degree of moisture-proof and water immersion prevention sealing of the electric appliance. A larger digit indicates a higher protection level. The heat dissipation apparatus <NUM> disposed in the power distribution room <NUM> adopts a sealed heat dissipation manner, to ensure the protection level of the power distribution room <NUM>.

Specifically, to facilitate operation and maintenance of the power distribution room <NUM>, there may be two side-open doors <NUM> disposed on the side wall in the width direction of the box body. The heat dissipation apparatus <NUM> may be disposed on one of the two side-open doors <NUM>, and an observation window <NUM> may be disposed on the other of the two side-open doors <NUM>. The observation window <NUM> may be disposed to facilitate observation of an interior of the power distribution room <NUM>. In addition, when the power distribution room <NUM> needs to be maintained or an operation is performed in the power distribution room <NUM>, the side-open door <NUM> provided with the observation window <NUM> may be opened for entering the power distribution room <NUM>.

In a possible embodiment, the side-open door may be provided on the side wall of the controller room in the width direction of the box body, and the heat dissipation apparatus may be disposed on the side-open door. Because a requirement of the protection level of the controller room is relatively low, the heat dissipation apparatus disposed on the side-open door of the controller room may be non-sealed. Specifically, the heat dissipation apparatus may be a cooling fan.

In a possible embodiment, <FIG> is still another schematic diagram of a structure of distribution of the controller room <NUM> and the power distribution room <NUM>. As shown in <FIG>, in the height direction of the box body, the controller room <NUM> may also be provided below the power distribution room <NUM>. In this case, the controller room <NUM> may be provided with the air outlet on the side wall in the width direction of the box body. The controller room <NUM> may be provided with the air inlet on the side wall in the length direction of the box body. The air inlet and the air outlet form the heat dissipation channel. The air may enter the controller room <NUM> through the air inlet. In this way, the heat generated by the control device in the controller room <NUM> is transferred from the controller room <NUM> to outside of the controller room <NUM>, so that the control device in the controller room <NUM> can work stably.

A plurality of groups of the mounting bracket assemblies may be disposed in the controller room <NUM>. Each of the groups of the mounting bracket assemblies may include the plurality of mounting bracket assemblies disposed in the height direction of the box body, and the two adjacent groups of the mounting bracket assemblies are disposed at intervals in the width direction of the box body.

When each of the groups of the mounting bracket assemblies includes the plurality of mounting bracket assemblies disposed in the height direction of the box body, to improve the convenience of mounting the control device in the controller room <NUM> and the convenience of detection, the mounting bracket assembly may include the fixed part and the sliding part. The end of the fixed part may be fastened to the side wall of the controller room <NUM> facing the side of the battery compartment, and the fixed part may be provided with the extension part extending to the side away from the battery compartment <NUM>. The slide rail may be disposed on the side that is of the extension part and that faces away from the power distribution room <NUM>.

In addition, the mounting bracket assemblies disposed in the controller room <NUM> may also be disposed at intervals in the width direction of the box body. In this case, there is the specific gap between the top of each of the mounting bracket assemblies and the top wall of the controller room <NUM>, so that the air passing through the air inlet can enter between the two adjacent mounting bracket assemblies through the gap, to take away the heat generated by the control device disposed on the mounting bracket assembly, so as to ensure that each control device can run stably.

When the plurality of mounting bracket assemblies are arranged at intervals in the width direction of the box body, to improve the convenience of mounting the control device in the controller room <NUM> and the convenience of detection, the mounting bracket assembly may include the fixed part and the sliding part. The fixed part may be the mounting bracket of which the end is fastened to the side wall of the controller room <NUM> facing the side of the battery compartment <NUM>, and the mounting bracket extends to the side away from the side wall. The accommodating cavity for accommodating the sliding part is provided on the mounting bracket. The accommodating cavity has the opening on the side away from the side wall. The bottom of the accommodating cavity is provided with the slide rail. The extension direction of the slide rail is the same as the length direction of the box body. The slide rail is perpendicular to the side wall. The sliding part is provided with the slide groove that matches the slide rail. The end of the slide groove away from the slide rail may be directly connected to the control device, or the bearing part for mounting the control device is provided at the end of the slide groove away from the slide rail. In this way, the control device is mounted in the mounting bracket assembly.

To improve the protection level of the controller room <NUM>, the protective apparatus <NUM> may be disposed at the air outlet. The protective apparatus <NUM> may be disposed to reduce the impurities entering the controller room <NUM> from the air outlet, and improve the dust-proof, sand-proof, and waterproof capabilities of the controller room <NUM>. In addition, when the protective apparatus <NUM> is disposed at the air outlet, the protective apparatus <NUM> may also be disposed at the air inlet. In this case, the protective apparatus <NUM> is disposed at both the air inlet and the air outlet, and the protection level of the controller room <NUM> may reach IP21, leading to the stronger dust-proof, sand-proof, and waterproof capabilities of the controller room <NUM>.

In a possible embodiment, <FIG> is still another schematic diagram of the structure of distribution of the controller room <NUM> and the power distribution room <NUM>, and <FIG> is used to show a specific structure in the controller room <NUM> in this case. <FIG> is a schematic diagram of the structure of the energy storage container provided with the protective apparatus at the air inlet <NUM> in <FIG>. As shown in <FIG>, in the function compartment and in the width direction of the box body, the power distribution room <NUM> and the controller room <NUM> may be disposed in parallel in the width direction of the box body. In this case, the controller room <NUM> is provided with the air outlet on the side wall in the width direction of the box body. The controller room <NUM> is provided with the air inlet <NUM> on the side wall in the length direction of the box body. The heat dissipation channel may be formed between the air inlet <NUM> and the air outlet. The air may enter the controller room <NUM> through the air inlet <NUM>. When the air in the controller room <NUM> passes through the control device <NUM> in the controller room <NUM>, the heat generated by the control device <NUM> may be taken away and discharged from the air outlet, so that the control device <NUM> in the controller room <NUM> can work stably. In this arrangement form, the plurality of mounting bracket assemblies <NUM> located in the controller room <NUM> for mounting the control device <NUM> may be disposed at intervals in the height direction of the box body. In this way, the air entering from the air inlet <NUM> may flow through the gap between two control devices <NUM>, to take away the heat generated by the control device <NUM>.

When the power distribution room <NUM> and the controller room <NUM> are provided in parallel in the width direction of the box body, and the plurality of mounting bracket assemblies <NUM> disposed in the controller room <NUM> may be disposed at intervals in the height direction of the box body, the fixed part included in the mounting bracket assembly <NUM> may be the slide rail disposed on the two side walls of the controller room <NUM> in the length direction of the box body, and the slide rail extends in the width direction of the box body. The slide rail may be parallel to the bottom wall of the controller room <NUM>, or when the slide rail extends from the air inlet <NUM> to the side away from the air inlet, the distance between the slide rail and the bottom wall of the controller room <NUM> gradually decreases. The sliding part may be the slide groove disposed on two sides of the control device <NUM>, and the slide groove matches the slide rail to enable the control device <NUM> to slide in the extension direction of the slide rail. Due to an arrangement manner of the slide rail, when the control device <NUM> is required to be detected or operated, the control device <NUM> may be directly slid out of the slide rail. After the detection or operation is completed, the control device <NUM> is directly pushed to an initial position. In addition, when the control device <NUM> reaches the initial position, the control device <NUM> may be stably disposed at the position, to ensure that the control device <NUM> can work stably.

In a specific implementation process, the protective apparatus <NUM> may be disposed at the air outlet. The protective apparatus <NUM> may be disposed to reduce the impurities entering the controller room <NUM> from the air outlet, and improve the dust-proof, sand-proof, and waterproof capabilities of the controller room <NUM>. In addition, when the protective apparatus <NUM> is disposed at the air outlet, the protective apparatus <NUM> may also be disposed at the air inlet. In this case, the protective apparatus <NUM> is disposed at both the air inlet and the air outlet, leading to the stronger dust-proof, sand-proof, and waterproof capabilities of the controller room <NUM>.

The power distribution room <NUM> provided in parallel with the controller room <NUM> in the width direction of the box body may be provided with the side-open door on the side wall in the length direction of the box body. In this case, the side-open door is disposed opposite to the air inlet <NUM> of the controller room <NUM>, and the heat dissipation apparatus may be disposed on the side-open door. The heat dissipation apparatus can dissipate heat for the power distribution room <NUM>. The requirement of the protection level of the power distribution room <NUM> is high. The heat dissipation apparatus may be configured as an air conditioner, so that when the heat dissipation apparatus cools the power distribution room <NUM>, the power distribution room <NUM> may remain relatively sealed.

It should be noted that the side-open door on the power distribution room <NUM> may be provided on the side wall in the width direction of the box body. In this case, an arrangement manner of the controller room <NUM> provided in parallel with the power distribution room <NUM> is the same as that of the side-open door of the power distribution room <NUM> provided on the side wall in the length direction of the box body.

In the foregoing embodiment, to improve safety performance of the box body, a protective layer may be provided between the battery compartment and the function compartment. The protective layer may have a fireproof function and a heat preservation function.

In the foregoing embodiment, <FIG> is a schematic diagram of a partial view of the battery compartment according to any one of the foregoing embodiments. As shown in <FIG>, in the length direction of the box body, the battery compartment <NUM> may be divided into a plurality of accommodating spaces <NUM>. In the length direction of the box body, two adjacent accommodating spaces <NUM> are communicated. Each of the accommodating spaces <NUM> is provided with a side door <NUM> on the side wall in the length direction of the box body, and the battery rack is disposed in each of the accommodating spaces <NUM>. Specifically, in the width direction of the box body, two battery racks may be disposed in each of the accommodating spaces <NUM>. The slide rail is disposed on a bottom wall of each of the accommodating spaces <NUM>. The slide groove matching the slide rail is disposed on the battery rack, or the slide groove is disposed on the bottom wall of each of the accommodating spaces. The slide rail matching the slide groove is disposed on the battery rack. In addition, the slide rail and the slide groove extend in the width direction of the box body, so that the battery rack is installed in the accommodating space at a position in which the side door <NUM> is provided in the box body. To improve stability of the battery rack installed in the accommodating space, a locking mechanism may be disposed in the accommodating space. The locking mechanism is configured to fasten a position of the battery rack in the accommodating space. In the height direction of the box body, a plurality of accommodation slots for accommodating the battery packs are disposed on the battery rack, and in the height direction of the box body, two adjacent accommodation slots are distributed at intervals. In this arrangement manner, side doors <NUM> are provided on two sides of each of the accommodating spaces <NUM>. When any one of the battery racks in the accommodating space <NUM> is overhauled and maintained, the side door <NUM> corresponding to the accommodating space <NUM> may be opened. That is, the battery rack and the battery pack in the accommodating space <NUM> may be overhauled and maintained. In this way, there is no need to provide a channel for overhaul and maintenance inside the battery compartment <NUM>. Thus, as compared with an energy storage container having a maintenance channel, this effectively improves the space utilization of the energy storage container and increases energy storage density.
