[0002] Battery electric vehicles (BEV) refer to vehicles that use an onboard power source as a power source, use an electric motor to drive the wheels, and comply with various requirements of road traffic and safety regulations. As they have less impact on the environment than traditional cars and have lower travel costs, the use of battery electric vehicles is becoming more and more widespread.
[0003] In the development of electric vehicles, battery swapping vehicles and battery swapping technologies are gradually being paid attention to. Thermal runaway is inevitable during the battery charging process in battery swapping stations. When a higher level of thermal runaway occurs, the battery needs to be transferred out of the battery swapping station to a suitable location for fire isolation.
[0004] For fire extinguishing of power batteries, flooding with water is a more effective method. When using water flooding for fire fighting in cold areas, there is freezing phenomenon. Therefore, the batteries in the battery swap station must ensure that there is enough liquid water to cooperate with the fire fighting water flooding operation to improve the fire extinguishing efficiency and protect the safety of the battery swap station.

DETAILED DESCRIPTION
[0024] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0025] Example
[0026] like Figure 1-4 As shown, this embodiment provides a fire-fighting device, including a built-in water tank 1-1, a conveying device 1-3 and an external water tank 1-5, wherein the built-in water tank 1-1 and the external water tank 1-5 are connected through a pipe assembly 1-2. Specifically, in this embodiment, the pipe assembly 1-2 includes a water pipe and a solenoid valve installed on the water pipe, and the solenoid valve is connected to the battery swap station system and can perform an opening and closing function according to the instructions of the battery swap station;
[0027] The external water tank 1-5 includes an actuator 2-1, a storage rack 2-2 and a fire curtain 2-3, wherein the actuator 2-1 is arranged in the external water tank 1-5;
[0028] The conveying device 1-3 is arranged on one side of the external water tank 1-5, wherein the conveying device 1-3 can convey the battery assembly 1-4 into the external water tank 1-5. Its main function is to cooperate in transferring the thermal runaway power battery from the corresponding thermal runaway battery in the storage room (battery exchange compartment 4-0) to the external fire water tank (ie, the external water tank 1-5).
[0029] The external water tank 1-5 also includes a storage rack 2-2 on the top and a shell 2-4, wherein a fire curtain 2-3 is installed in the shell 2-4. The fire curtain 2-3 can prevent open flames from entering the battery exchange compartment 4-0 to ensure fire safety.
[0030] The conveying device 1-3 includes a carrier 3-2, wherein a chain plate assembly 3-3 and a driving device 3-1 for driving the chain plate assembly 3-3 are arranged on the carrier 3-2 for conveying the battery assembly 1-4.
[0031] The present embodiment also provides a passenger car battery swap station having the aforementioned fire-fighting device, wherein the internal water tank 1-1 is arranged at the top of the battery swap compartment 4-0, and the external water tank 1-5 is arranged outside the battery swap compartment 4-0.
[0032] Since the built-in water tank 1-1 is set inside the battery exchange compartment 4-0, it ensures that the fire-fighting water will not be frozen in a low-temperature environment. One of the typical implementation processes is: when the fire-fighting operation command is triggered, the system will control the connecting pipe component 1-2 to open its solenoid valve to inject the fire-fighting liquid water from the built-in water tank into the external water tank 1-5. At the same time, the conveyor line cooperates to put the power batteries transferred to the line into the temporary storage rack (storage rack 2-2) of the external water tank 1-5. When the fault level reaches the level that requires flooding, the execution cylinder will open the lock block to sink the battery temporary storage rack together with the power battery into the water.
[0033] The fire-fighting device of the present invention ensures the supply of liquid water by arranging a built-in water tank 1-1 in the battery swap compartment, especially in cold areas. Since the temperature in the battery swap compartment 4-0 is generally above zero degrees, it can ensure that sufficient liquid water can be provided to the external water tank 1-5 for fire extinguishing, which is safer and realizes fire safety protection for passenger car battery swap stations; the conveying device 1-3 can place the battery assembly 1-4 in the external water tank 1-5 for waiting, and the execution component 2-1 will drop the battery assembly 1-4 into the external water tank 1-5 when fire extinguishing is needed, thereby improving the accuracy and efficiency of fire extinguishing.
[0034] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of protection claimed by the utility model. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
