Electric vehicle users can use the battery swapping cabinet to replace their batteries themselves, so that they do not have to wait for a long time to charge.

[0003] To ensure the electrical safety of the battery swapping cabinet, the through-slot in the cabinet is equipped with a fire extinguishing device. However, in related technologies, the fire extinguishing device has poor fire extinguishing effect and is prone to reignition after the fire is extinguished. Summary of the Invention

[0004] The purpose of this application is to provide a battery swapping cabinet that addresses the problems of poor fire extinguishing effect and easy reignition after fire suppression in existing battery swapping cabinets.

[0005] To achieve the objectives of this application, this application provides a battery swapping cabinet, the battery swapping cabinet comprising:

[0006] Battery compartment, used to store batteries;

[0007] A fire extinguishing chamber, wherein an opening is provided on one side;

[0008] An actuator is used to transport the battery compartment from the opening into the fire extinguishing chamber to continuously block oxygen from the area surrounding the battery compartment.

[0009] In one possible implementation, the battery compartment wall is provided with a through hole communicating with the inner cavity of the battery compartment. The fire extinguishing compartment is used to store a first fire extinguishing agent. When the battery compartment is located inside the fire extinguishing compartment, the first fire extinguishing agent enters the battery compartment through the through hole.

[0010] In one possible implementation, the battery swapping cabinet further includes a first fire extinguishing agent replenishment structure, which is used to replenish the first fire extinguishing agent in the fire extinguishing chamber.

[0011] In one possible implementation, the battery swapping cabinet includes multiple battery compartments and multiple fire extinguishing compartments, with each fire extinguishing compartment corresponding to each of the battery compartments.

[0012] The first extinguishing agent replenishment structure includes a connecting channel, which is located between each adjacent extinguishing chamber and is used for the flow of the first extinguishing agent.

[0013] In one possible implementation, the battery swapping cabinet further includes a fire extinguishing agent releaser for releasing a second fire extinguishing agent into the fire extinguishing chamber.

[0014] In one possible implementation, the extinguishing agent releaser includes:

[0015] A capsule, wherein the capsule is disposed within the fire extinguishing chamber, and the capsule is filled with the second extinguishing agent; and

[0016] A puncturing element for puncturing the capsule and releasing the second extinguishing agent.

[0017] In one possible implementation, the puncturing member protrudes from the outer surface of the battery compartment and is used to puncture the bladder when the battery compartment enters the fire extinguishing chamber.

[0018] In one possible implementation, the battery compartment and the fire extinguishing compartment are arranged along a first direction, the opening is located at one end of the battery compartment in the first direction, and the battery compartment enters the fire extinguishing compartment through the opening along the first direction.

[0019] In one possible implementation, one end of the puncture member is connected to the battery compartment, and the other end extends in a first direction.

[0020] In one possible implementation, the actuator includes a drive motor and cables;

[0021] The drive motor, the battery compartment, and the fire extinguishing compartment are arranged sequentially along the first direction, which is vertical.

[0022] One end of the cable is wound around the output shaft of the drive motor, and the other end is connected to the battery compartment, so that the output shaft can drive the battery compartment to enter the fire extinguishing chamber in the first direction.

[0023] In one possible implementation, the battery swapping cabinet further includes a temperature sensor for detecting the temperature of the battery compartment;

[0024] When the temperature detected by the temperature sensor is greater than a first preset threshold, the actuator moves the battery compartment into the fire extinguishing chamber.

[0025] In one possible implementation, the battery swapping cabinet further includes a smoke sensor for detecting the particulate concentration in the air inside the battery swapping cabinet;

[0026] When the particle concentration detected by the smoke sensor is greater than the second preset threshold, the actuator places the battery compartment into the fire extinguishing chamber.

[0027] In one possible implementation, the battery compartment includes a compartment body and a cover plate fixedly disposed on one end of the compartment body;

[0028] The cover plate is used to cover the opening when the battery compartment enters the fire extinguishing chamber.

[0029] In this technical solution, the battery swapping cabinet is equipped with a fire extinguishing chamber. When a battery catches fire, the battery, along with its compartment, enters the fire extinguishing chamber through an opening on one side, driven by an actuator. The fire extinguishing chamber continuously blocks oxygen from the area surrounding the battery compartment, thus disrupting the ignition conditions, inhibiting combustion, extinguishing the flame, and reducing the possibility of reignition. Furthermore, compared to extinguishing the fire at the battery compartment location, moving the battery compartment to a dedicated fire extinguishing chamber separates the fire extinguishing and storage functions of the battery swapping cabinet.

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or it can be in a middle component. When a component is said to be "connected" to another component, it can be directly connected to the other component or it may be in a middle component.

[0049] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terminology used in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0050] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0051] Battery swapping cabinets enable rapid battery replacement, ensuring extended range for electric vehicles and meeting travel needs. They are particularly suitable for riders, delivery personnel, couriers, and other users who frequently use electric vehicles for extended periods. Through battery sharing and exchange, they effectively solve the problems of slow charging and long waiting times for electric vehicle batteries. Specifically, users can place the battery needing charging into the cabinet and retrieve a fully charged battery for their electric vehicle, thus extending its range.

[0052] Typically, a battery swapping cabinet consists of a cabinet body and multiple battery compartments housed within it. Each battery compartment has a door for easy storage and retrieval of batteries. The cabinet contains an AC module and a rectifier module. Each battery compartment also has a charging module located on the side opposite the door. The battery swapping cabinet is connected to an external power supply system via the AC module. The AC module and rectifier module are electrically connected, the rectifier module is electrically connected to the charging module, and the charging module is electrically connected to the battery compartment, thus supplying power to the batteries within.

[0053] Batteries pose a risk of spontaneous combustion during charging. Therefore, battery swapping cabinets are usually equipped with fire extinguishing devices. In related technologies, the fire extinguishing devices of battery swapping cabinets typically use aerosols to spray the battery ignition point at a fixed point. This method of fire extinguishing has a short extinguishing time, poor extinguishing effect, and is mostly a one-time extinguishing method, which cannot prevent the battery from reigniting.

[0054] To address the aforementioned issues, this application proposes a battery swapping cabinet. In addition to the cabinet body and battery compartment, the cabinet includes a fire extinguishing compartment and an actuator. When a battery catches fire, the battery, along with its compartment, is drawn into the fire extinguishing compartment through an opening on one side, driven by the actuator. The fire extinguishing compartment continuously blocks oxygen from the area surrounding the battery compartment, thus disrupting the ignition conditions, extinguishing the flame, and reducing the possibility of reignition. Furthermore, compared to extinguishing the fire at the battery compartment location, moving the battery compartment to a dedicated fire extinguishing compartment separates the fire extinguishing and storage functions of the swapping cabinet. This allows for dedicated cabinet use, and the fire extinguishing design is not limited by the battery storage location. It also avoids the problem of personnel having to open the cabinet door to retrieve burning or extinguished batteries after a fire has occurred.

[0055] The following description, in conjunction with the accompanying drawings, provides a detailed account of the battery swapping cabinet provided in the embodiments of this application.

[0056] Please refer to Figure 1 and Figure 2 The battery swapping cabinet 100 includes a cabinet body 7, which is the supporting structure of the entire battery swapping cabinet 100. The shape of the cabinet body 7 can be a cube or other regular or irregular shape, and this application does not limit it. For example, in one embodiment of this application, the cabinet body 7 adopts a cuboid structure to facilitate the arrangement of the battery compartment 1 and the fire extinguishing compartment 2.

[0057] The battery compartment 1 is housed within the cabinet 7. The battery compartment 1 includes a compartment body 11 and a cover plate 12 fixedly disposed at one end of the compartment body 11. The compartment body 11 forms a battery cavity, in which the battery is housed. The surface of the compartment body 11 has through holes 13 communicating with the battery cavity for heat dissipation. The cover plate 12 covers the battery cavity to protect the battery located within it.

[0058] Fire extinguishing chamber 2 is arranged along the first direction on one side of battery compartment 1. Fire extinguishing chamber 2 is used to continuously block oxygen around battery compartment 1, thereby disrupting the conditions for battery ignition. One or more fire extinguishing chambers 2 can be installed. When only one fire extinguishing chamber 2 is installed, all battery compartments 1 within the battery swapping cabinet 100 share the same fire extinguishing chamber 2. When multiple fire extinguishing chambers 2 are installed, each fire extinguishing chamber 2 corresponds to one battery compartment 1.

[0059] The first direction can be vertical, horizontal, or inclined; this application does not limit this. In one embodiment of this application, the first direction is set to vertical, and the fire extinguishing chamber 2 has an opening 21 opposite to the battery compartment 1. The battery compartment 1 can enter the fire extinguishing chamber 2 through the opening 21 along the first direction. This allows the battery compartment 1 to enter the fire extinguishing chamber 2 with the shortest distance, improving the response speed of the battery swapping cabinet 100 to battery fire extinguishing and reducing the impact of battery fire on the battery swapping cabinet 100.

[0060] There are several ways to continuously block oxygen around the battery compartment 1 in the fire extinguishing chamber 2. In one embodiment of this application, the area of ​​the cover plate 12 is larger than the area of ​​the opening 21 of the fire extinguishing chamber 2. When the battery compartment enters the fire extinguishing chamber, the body 11 of the battery compartment 1 falls into the fire extinguishing chamber 2, and the cover plate 12 covers the opening 21 of the fire extinguishing chamber 2. In this way, a sealed environment is formed inside the fire extinguishing chamber 2, preventing air exchange between the fire extinguishing chamber 2 and the outside, thereby destroying the ignition conditions of the battery and inhibiting battery combustion. Moreover, when the battery explodes due to excessive temperature, the combination of the cover plate 12 and the fire extinguishing chamber 2 can also block the flying debris from the battery explosion, thereby reducing the harm to people around the battery swapping cabinet 100 caused by the flying debris after the battery explosion.

[0061] To continuously block oxygen, in some other possible embodiments of this application, an electric door may be installed at the opening 21 of the fire extinguishing chamber 2. When the battery compartment 1 enters the fire extinguishing chamber 2 through the opening 21, the electric door will close the opening 21, thereby preventing air exchange between the fire extinguishing chamber 2 and the outside. After the battery has burned off the remaining oxygen in the fire extinguishing chamber 2, it will extinguish due to insufficient oxygen and there is no possibility of reignition.

[0062] Besides using a cover plate 12 or an electric hatch to close the opening 21, the fire extinguishing chamber 2 can also block oxygen around the battery compartment 1 through other means. In other embodiments of this application, the fire extinguishing chamber 2 is filled with a first extinguishing agent 4, which can be water or fire extinguishing foam; this application does not limit this. In this embodiment, the first extinguishing agent 4 is water. Firstly, compared to fire extinguishing foam, water has better encapsulation of the battery compartment 1, stronger oxygen isolation ability, and can stably isolate the air around the battery compartment 1 for a long time. Secondly, at the high temperature of battery combustion, water evaporates instantly upon contact with the battery compartment 1, carrying away a large amount of heat from the battery compartment 1, lowering the temperature of the battery compartment 1, disrupting the ignition conditions of the battery, and inhibiting battery combustion. Thirdly, water is low in cost and easy to store, making it suitable for long-term placement in the battery swapping cabinet 100. When the battery compartment 1 enters the fire extinguishing compartment 2 through the opening 21, the water filling the fire extinguishing compartment 2 can enter the battery cavity through the through hole 13 of the battery compartment 1, reduce the battery temperature, suppress the exchange area between the battery and oxygen, destroy the ignition point of the battery, and extinguish the battery flame.

[0063] The actuator 3 of the battery swapping cabinet 100 is used to transport the battery compartment 1 from the opening 21 into the fire extinguishing chamber 2. The actuator 3 can be a motor lead screw or a cylinder; this application does not limit this. In one embodiment of this application, the actuator 3 includes a drive motor 31 and a cable 32. The drive motor 31, the battery compartment 1, and the fire extinguishing chamber 2 are arranged sequentially along a first direction, which can be vertical or horizontal; this application does not limit this. Considering that the fire extinguishing chamber may store a first extinguishing agent, in this embodiment, the first direction is preferably vertical. The drive motor 31 is fixedly connected to the cabinet 7, and one end of the cable 32 is wound around the drive motor 31, while the other end is fixedly connected to the battery compartment 1, so that the output shaft can drive the battery compartment 1 into the fire extinguishing chamber 2 along the first direction. When the battery is not on fire, the battery compartment 1 is suspended above the fire extinguishing chamber 2 by the cable 32. When the battery catches fire, the drive motor 31 rotates and releases the cable 32 downwards. Battery compartment 1 is hoisted by cable 32 and enters fire extinguishing compartment 2 through opening 21.

[0064] The battery swapping cabinet 100 also includes a fire extinguishing agent releaser 5, which releases a second fire extinguishing agent into the fire extinguishing compartment 2. After release, the second fire extinguishing agent quickly adheres to the surface of the battery compartment 1, blocking oxygen exchange between the battery compartment and the outside environment, disrupting the ignition conditions of the battery, and inhibiting battery combustion. Secondly, upon contact with the battery compartment, the second fire extinguishing agent rapidly vaporizes, thereby carrying away heat from the battery compartment and protecting battery safety. Thirdly, the second fire extinguishing agent can capture free radicals in the combustion chain reaction, terminating the chain reaction of flame propagation.

[0065] The second extinguishing agent can be carbon dioxide, perfluorohexanone, or hexafluoropropane; this application does not limit this. Exemplarily, in one embodiment of this application, perfluorohexanone is used as the second extinguishing agent. Compared to other first extinguishing agents 4, perfluorohexanone evaporates less when heated, generates a higher vapor pressure, and can carry away more heat within the same volume. Furthermore, perfluorohexanone is chemically stable and easy to store, making it suitable for use as fire-fighting equipment.

[0066] Understandably, the extinguishing agent releaser 5 can not only extinguish fires in the battery compartment alone, but also be used in conjunction with the first extinguishing agent 4. Specifically, in one embodiment of this application, the second extinguishing agent of the extinguishing agent releaser 5 is released into the first extinguishing agent 4, and then comes into contact with the battery compartment 1 through the first extinguishing agent 4. This arrangement has two advantages: firstly, for the second extinguishing agent, the first extinguishing agent 4 can increase the contact area between the second extinguishing agent and the battery compartment 1, thereby improving the extinguishing effect of the first extinguishing agent 4 on the battery compartment 1. Secondly, for the first extinguishing agent 4, evaporation occurs during the extinguishing process, resulting in the portion of the battery compartment 1 originally containing the first extinguishing agent 4 being exposed. The second extinguishing agent can fill this space, thus maintaining the oxygen isolation of the battery compartment 1.

[0067] The structure of the extinguishing agent releaser 5 can vary. In some embodiments, the extinguishing agent releaser 5 includes a housing, a hydraulic pump, and a solenoid valve. The housing is fixed to the fire extinguishing chamber 2 or the cabinet 7. The housing forms a pressure chamber with a liquid outlet. The pressure chamber is connected to the fire extinguishing chamber 2 through the liquid outlet. The pressure chamber stores a second extinguishing agent. The solenoid valve is located at the liquid outlet. When the extinguishing agent releaser 5 needs to release the second extinguishing agent, the solenoid valve opens, the pressure chamber is connected to the fire extinguishing chamber 2, and the second extinguishing agent is released into the fire extinguishing chamber 2 through the liquid outlet under the action of the hydraulic pump.

[0068] In one embodiment of this application, the extinguishing agent releaser 5 includes a bladder 51 and a puncture member 52. The bladder 51 is disposed within the fire extinguishing chamber 2. One or two bladders 51 can be provided; this application does not limit this. Exemplarily, in this embodiment, the extinguishing agent releaser 5 includes two bladders 51, which are spaced apart within the fire extinguishing chamber 2 along its width. The bladder 51 is filled with a second extinguishing agent. The puncture member 52 can puncture the bladder 51 when the second extinguishing agent needs to be released, thereby releasing the second extinguishing agent. Compared to using a hydraulic pump, the structure of the bladder 51 and the puncture member 52 is simpler, occupies less space in the fire extinguishing chamber 2, and has lower installation costs.

[0069] There are various ways in which the puncturing element 52 punctures the bladder 51. In one embodiment of this application, the extinguishing agent releaser 5 also includes a linear motor, and the puncturing element 52 is mounted on the linear motor. When the extinguishing agent releaser 5 needs to release the second extinguishing agent, the power switch cabinet 100 will drive the linear motor to move. The movement of the linear motor will drive the puncturing element 52 to move, and the puncturing element 52 will come into contact with the bladder 51, thereby releasing the second extinguishing agent inside the bladder 51.

[0070] Understandably, the puncture member 52 can also be driven in other ways. In another embodiment of this application, the puncture member 52 protrudes from the outer surface of the battery compartment 1 and can move downwards with the battery compartment 1. Thus, when the battery compartment 1 falls into the fire extinguishing chamber 2, the battery compartment 1 comes into contact with the first extinguishing agent 4 inside the fire extinguishing chamber 2, and the puncture member 52 comes into contact with the bladder 51 inside the fire extinguishing chamber 2, releasing the second extinguishing agent. This embodiment can drive both the first and second extinguishing agent fire extinguishing methods through a single downward movement of the battery compartment 1, optimizing the structure of the extinguishing agent releaser 5, reducing the manufacturing cost of the extinguishing agent releaser 5, reducing the volume of the battery swapping cabinet 100, and increasing the energy density of the battery swapping cabinet 100.

[0071] Understandably, when the piercing element 52 is located on the outer surface of the battery compartment 1, the piercing element 52 can be arranged horizontally or vertically, and this application does not impose any restrictions on this. In one embodiment of this application, the bladder 51 is located at the bottom of the fire extinguishing chamber 2, and the battery compartment 1 enters the fire extinguishing chamber 2 through the opening 21 in the first direction. One end of the piercing element 52 is connected to the battery compartment 1, and the other end extends in the first direction. The direction in which the piercing element 52 is located is the same as the direction in which the battery compartment 1 enters the fire extinguishing chamber 2. In this way, the sharp part of the piercing element 52 can pierce into the bladder 51 in a direction perpendicular to the surface of the bladder 51, thereby accelerating the speed at which the piercing element 52 pierces the bladder 51, accelerating the release speed of the second extinguishing agent, and improving the response speed of the extinguishing agent releaser 5. The puncture component 52 can be a protruding structure fixedly connected to the outer surface of the battery compartment 1. For example, the protruding structure can be a triangular prism or a protrusion. In this case, the spike can correspond to the corner of the triangular prism, the edge of the protrusion, or an additional spike structure.

[0072] The battery swapping cabinet 100 also includes a first extinguishing agent replenishment structure 6. When the first extinguishing agent 4 in the fire extinguishing chamber 2 is lost due to evaporation, the first extinguishing agent replenishment structure 6 can quickly replenish the first extinguishing agent 4 in the fire extinguishing chamber 2, thereby avoiding the problem that the air isolation capability of the fire extinguishing chamber 2 to the battery compartment 1 will decrease due to the evaporation of the first extinguishing agent 4.

[0073] The first extinguishing agent replenishment structure 6 can take various forms. For example, in one embodiment of this application, the first extinguishing agent replenishment structure 6 includes a water tank, a water pump, and a water level sensor. The water tank stores the first extinguishing agent 4, and the water tank is connected to the fire extinguishing chamber 2 via the water pump. The water level sensor is located inside the fire extinguishing chamber 2 to sense the water level of the first extinguishing agent 4 inside the fire extinguishing chamber 2. In practice, when the water level in the fire extinguishing chamber 2 drops to a third preset threshold, the water level sensor transmits this information to the data terminal of the battery swapping cabinet 100. The data terminal controls the water pump to pump the first extinguishing agent 4 from the water tank into the fire extinguishing chamber 2, thereby replenishing the first extinguishing agent 4 in the fire extinguishing chamber 2 and preventing the first extinguishing agent 4 from evaporating and affecting the air barrier capability of the fire extinguishing chamber 2.

[0074] In another possible embodiment of this application, the first extinguishing agent replenishment structure 6 can also be a connecting channel 6a. Specifically, in this embodiment, the battery swapping cabinet 100 is provided with multiple fire extinguishing chambers 2, each fire extinguishing chamber 2 corresponding to a battery compartment 1. A connecting channel 6a is provided between each adjacent fire extinguishing chamber 2. This connecting channel 6a can be a conduit or part of the structure of the fire extinguishing chamber 2, and this application does not limit this. Each adjacent fire extinguishing chamber 2 is connected through the connecting channel 6a. With this configuration, when the burning battery compartment 1 falls into the target fire extinguishing chamber 2 under the drive of the actuator 3, the first extinguishing agent 4 in the target fire extinguishing chamber 2 can enter other fire extinguishing chambers 2 through the connecting channel 6a, thereby preventing the first extinguishing agent 4 from overflowing from the opening 21 of the target fire extinguishing chamber 2 due to insufficient volume, which would damage other components in the battery swapping cabinet 100. When the first extinguishing agent 4 in the target fire extinguishing chamber 2 decreases in height due to evaporation, the first extinguishing agent 4 flowing into other fire extinguishing chambers 2 will flow back into the target fire extinguishing chamber 2 through the connecting channel 6a, thereby replenishing the first extinguishing agent 4 lost in the target fire extinguishing chamber 2. Understandably, to improve the fire extinguishing effect of the battery swapping cabinet 100, multiple fire extinguishing chambers 2 are generally installed inside the battery swapping cabinet 100. By setting the first extinguishing agent replenishment structure 6 as the connecting channel 6a, the structure of the battery swapping cabinet 100 itself can be fully utilized, reducing the installation cost of the first extinguishing agent replenishment structure 6, optimizing the spatial layout of the battery swapping cabinet 100, reducing the volume of the battery swapping cabinet 100, and increasing the energy density of the battery swapping cabinet 100.

[0075] Please refer to the reference. Figures 1 to 4 To monitor whether the battery is on fire, the battery swapping cabinet 100 also includes a system controller 8. The system controller 8 is electrically connected to the battery in the battery compartment 1 to monitor the status of the battery in the battery compartment 1. When the battery status exceeds the safety threshold, the system controller 8 sends an alarm to the terminal, thereby driving the actuator 3 to move.

[0076] Specifically, the battery swapping cabinet 100 includes a temperature sensor 9, which is used to detect the temperature of the battery compartment 1. The temperature sensor 9 is electrically connected to the system controller 8. When the temperature detected by the temperature sensor 9 is greater than a first preset threshold, the system controller 8 determines that the battery is on fire. The system controller 8 controls the drive motor 31 to rotate and releases the cable 32, thereby hoisting the battery compartment 1 into the fire extinguishing chamber 2 to extinguish the fire on the battery.

[0077] The temperature sensor 9 can be located in the cabinet 7 or in the battery compartment 1; this application does not impose any restrictions on this. In one embodiment of this application, the temperature sensor 9 is located in the battery compartment 1 and is positioned close to the battery. This allows the temperature sensor 9 to promptly acquire the temperature of each battery and quickly determine the location of any burning battery.

[0078] The battery swapping cabinet 100 also includes a smoke sensor 10, which is electrically connected to the system controller 8. The smoke sensor 10 can be used in conjunction with the temperature sensor 9, or it can be used independently; this application does not impose any restrictions on this. When used independently, the smoke sensor 10 can monitor the particulate concentration in the air inside the battery swapping cabinet 100. When the particulate concentration detected by the smoke sensor 10 exceeds a second preset threshold, the smoke sensor 10 determines that the battery is on fire, and then transmits the information about the battery fire to the data terminal. The data terminal then drives the drive motor 31 to release the cable 32, thereby hoisting the battery compartment 1 into the fire extinguishing chamber 2 to extinguish the battery fire. When the smoke sensor 10 is used in conjunction with the temperature sensor 9, the smoke sensor 10 can correct the judgment structure of the temperature sensor 9 to avoid misjudging the battery temperature rise by the temperature sensor 9.

[0079] The movement of the battery swapping cabinet 100 of this application will now be described in general with reference to the accompanying drawings.

[0080] When the battery catches fire, its temperature rises and smoke is produced. The temperature rise and smoke levels are detected by temperature sensor 9 and smoke sensor 10 located within battery compartment 1. These sensors transmit the information to the system controller 8 of the battery swapping cabinet. When the battery temperature exceeds a first threshold, or the air particle concentration exceeds a second threshold, the system controller determines the battery is on fire and controls drive motor 31 to operate and release cable 32. Battery compartment 1, suspended by cable 32, enters fire extinguishing compartment 2 through its opening. The cover 12 of battery compartment 1 covers the opening of fire extinguishing compartment 2. The body 11 of battery compartment 1 contacts the first extinguishing agent 4 within fire extinguishing compartment 2. The first extinguishing agent 4 enters the body 11 through a through-hole and contacts the battery within. The puncture portion of body 11 contacts a capsule located at the bottom of fire extinguishing compartment 2, releasing the second extinguishing agent from the capsule. The second extinguishing agent is partially attached to the surface of the chamber body 11, while the other part floats upward and is suspended in the upper space of the extinguishing chamber 2 to completely enclose the chamber body 11.
