Then open the third control valve, start the circulating water pump, and pump the water in the water collection tank into the water tank through the circulating pipe, and continue to use water to extinguish the fire and cool the battery swap pack to prevent thermal expansion and secondary re-ignition of the battery swap pack. In this way, the water in the water tank can be used as both a coolant in the liquid-cooled fire-fighting system and as fire-fighting water for fire extinguishing and cooling in the liquid-cooled fire-fighting system, which greatly improves the safety of the charging and swapping energy storage cabinet.

[0042] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0043] The following is a detailed description of the technical solution of the present application and how the technical solution of the present application solves the above technical problems with specific embodiments. It should be noted that the following implementations can refer to, draw on or combine with each other, and the same terms, similar features and similar implementation steps in different implementations will not be described repeatedly.

[0044] The present application embodiment provides a charging and swapping energy storage cabinet. The structural diagram of the charging and swapping energy storage cabinet is as follows: Figures 1 to 4 As shown, it includes: a cabinet, multiple battery replacement packs, at least one energy storage pack, a water tank, an air cooling system, a liquid cooling fire protection system and a water circulation system.

[0045] The cabinet 1 includes a first accommodating space, a second accommodating space and a third accommodating space from bottom to top; the second accommodating space includes at least two battery compartment groups, each battery compartment group includes m rows and n columns of battery compartments 21, and m and n are both positive integers not less than 1.

[0046] The battery replacement pack 22 is installed in the battery compartment 21 .

[0047] At least one energy storage pack 3 is placed in the first accommodation space.

[0048] The water tank 4 is installed in the third accommodating space.

[0049] The air cooling system includes a first control valve (not marked in the figure) and a heat dissipation fan 51 connected to the first control valve; the heat dissipation fan 51 is installed at the middle position of both sides of the cabinet 1.

[0050] The liquid cooling fire fighting system includes a second control valve (not marked in the figure), a liquid inlet main pipe 61, at least two liquid outlet main pipes 62, a booster water pump 63 and a first spray pipe 64. The second control valve is connected to the booster water pump 63, one end of the liquid inlet main pipe 61 is connected to the water tank 4, and the other end is connected to the booster water pump 63. One end of a liquid outlet main pipe 62 is connected to the booster water pump 63, and the other end is connected to one end of m first liquid outlet branch pipes 65. The other end of a first liquid outlet branch pipe 65 is connected to at least one first spray pipe 64, and the first spray pipe 64 is installed on the top of the battery compartment 21.

[0051] The water circulation system includes a third control valve (not marked in the figure), a circulating water pump 71 connected to the third control valve, a water tank 4, a circulating pipe 72, a water collecting tray arranged at the bottom of each battery compartment 21, and a water collecting tank 73 for collecting water from each water collecting tray.

[0052] The booster water pump 63 and the circulating water pump 71 are both arranged in the first accommodation space; the water collecting tank 73 is arranged at the bottom of the first accommodation space.

[0053] When the temperature of the battery pack 22 is higher than the first set threshold, the first control valve is opened, the heat dissipation fan is started, and the battery pack 22 is cooled by air; when the temperature of the battery pack 22 is higher than the second set threshold or the fire is triggered, the second control valve is opened, the booster water pump 63 is started, and the surface of each battery pack 22 is sprayed with water through the first spray pipe 64; after the liquid cooling fire protection system works for the first set working time, the third control valve is opened, the circulating water pump 71 is started, and the spray water is pumped back into the water tank 4. The second set threshold is greater than the first set threshold.

[0054] In this embodiment, when the temperature of the battery swap pack 22 is higher than the first set threshold, only the first control valve can be opened, and the heat dissipation fan 51 can be started to cool the battery swap pack 22 with air, and the heat dissipation fan 51 draws the hot air in the cabinet 1 to the external environment. When the temperature of the battery swap pack 22 is higher than the second set threshold or the fire is triggered, the second control valve is opened, the booster water pump 63 is started, and the surface of the battery swap pack 22 is sprayed with water through the first spray pipe 64 to quickly cool the battery swap pack 22 by spraying water, thereby improving the safety of the charging and swapping energy storage cabinet. Selectively starting the air cooling system or the liquid cooling fire protection system according to the temperature of the battery swap pack 22 is conducive to reducing the energy consumption of the charging and swapping energy storage cabinet and improving the safety of the charging and swapping energy storage cabinet.

[0055] After the liquid-cooled fire-fighting system has been working for the first set working time, the water sprayed to each battery swap pack 22 through the first spray pipe 64 drips into the water collecting tray after passing through the guide groove 521 of the outer shell of the battery swap pack 22, and is collected in the water collecting tank 73. Then, the third control valve is opened, and the circulating water pump 71 is started to pump the water in the water collecting tank 73 into the water tank 4 through the circulating pipe 72, and the battery swap pack 22 is continuously sprayed with water to extinguish the fire and cool it down, so as to prevent the battery swap pack 22 from thermal expansion and secondary reignition. In this way, the water in the water tank 4 can be used as both a coolant in the liquid-cooled fire-fighting system and as fire-fighting water for fire extinguishing and cooling in the liquid-cooled fire-fighting system, which greatly improves the safety of the charging and swapping energy storage cabinet.

[0056] By adding a movable energy storage pack 3, the charging and swapping cabinet can be put into use when there is no mains power or the mains power is difficult to expand, thereby expanding the use scope of the charging and swapping energy storage cabinet.

[0057] It should be noted that when the first control valve is opened, the second control valve is closed; when the second control valve is opened, the first control valve can be opened or closed, that is, the air cooling system and the liquid cooling system can work separately or at the same time. For example, when the battery swap pack 22 catches fire, it is necessary to turn on the liquid cooling fire fighting system and turn off the air cooling system. When the temperature of the battery swap pack 22 is higher than the second set threshold, only the liquid cooling system can be turned on, or both the liquid cooling system and the air cooling system can be turned on at the same time.

[0058] In addition, the conditions that trigger firefighting include fire, smoke, etc.

[0059] It is understandable that the first set working time can be set according to the water level of the water collection tank 73 in the specific charging and swapping energy storage cabinet, and no limitation is made here.

[0060] Optionally, the liquid-cooled fire-fighting system also includes a fourth control valve (not marked in the figure) connected to the booster pump 63, at least one second liquid outlet branch pipe and at least one second spray pipe, one end of the second liquid outlet branch pipe is connected to the fourth control valve, and the other end is connected to the second spray pipe, and the second spray pipe is arranged above the energy storage package 3.

[0061] In this embodiment, the energy storage pack 3 can be cooled and fire extinguished by spraying water by controlling the fourth control valve.

[0062] Optionally, when the temperature of the energy storage pack 22 is higher than a second set threshold or firefighting is triggered, the fourth control valve is opened to spray the energy storage pack 3 through the second spray pipe.

[0063] Optionally, the liquid-cooled fire fighting system further includes a liquid cooling unit 8 and a heater (not marked in the figure).

[0064] When the water temperature in the water tank 4 is not lower than the third set threshold value, the liquid cooling unit 8 is started in valley power or emergency state to cool the water in the water tank 4 .

[0065] When the water temperature in the water tank 4 is not higher than the fourth set threshold value, the heater is started in a valley power or emergency state to heat the water in the water tank 4 .

[0066] In this embodiment, when the water temperature in the water tank 4 is not lower than the third set threshold value, illustratively, when the water temperature in the water tank 4 is not lower than 28°C, the water in the water tank 4 can be cooled and stored in the water tank 4 during off-peak power or emergency conditions. During peak power consumption, the liquid cooling unit 8 is turned off and the water in the water tank 4 is used to cool the battery swap pack 22.

[0067] Similarly, when the water temperature in the water tank 4 is not higher than the fourth set threshold value, for example, when the water temperature in the water tank 4 is not higher than 10°C, the water in the water tank 4 can be heated and stored in the water tank 4 during off-peak power or emergency conditions; during peak power consumption, turn off the heater and use the water in the water tank 4 to heat the battery swap pack 22.

[0068] Therefore, the battery swap pack 22 can be selectively cooled or heated during off-peak hours according to the environment and the temperature of the battery swap pack 22, which can significantly reduce the energy consumption of the charging and swapping energy storage cabinet and thus improve economic benefits.

[0069] Optionally, the battery swap package 22 also includes a fifth control valve (not marked in the figure) and a heating element (not marked in the figure) connected to the fifth control valve.

[0070] When the temperature of the battery swap pack 22 is not higher than the fifth set threshold, start the fifth control valve.

[0071] When the temperature of the battery swap pack 22 reaches the sixth set threshold, the fifth control valve is closed.

[0072] In this embodiment, when the temperature of the battery swap pack 22 is not higher than 0°C, the battery swap pack 22 needs to be heated before charging the battery swap pack 22. The battery swap pack 22 has a built-in heating element to facilitate heating of the battery swap pack 22.

[0073] Alternatively, the heating element may be a heating film or a heating tape.

[0074] Optionally, the air cooling system includes at least two ventilation ducts with m rows and n columns; the ventilation ducts are used to dissipate heat from the battery swap pack 22.

[0075] Optionally, refer to Figure 1 and Figure 3 The ventilation duct includes a plurality of ventilation openings 53 , the internal space of the battery compartment 21 and a guide groove 521 .

[0076] A plurality of ventilation holes 53 are arranged around the door of the battery compartment 21 and penetrate the door.

[0077] A guide groove 521 is provided on one or more sides of the outer shell of the battery swap pack 22 .

[0078] In this embodiment, a ventilation channel is formed by the vents 53, the internal space of the battery compartment 21 and the guide groove 521. The vents 53 are arranged around the battery compartment door, so that the cold air from the vents 53 flows through the guide groove 521 on the surface of the battery pack to dissipate heat from the battery pack 22.

[0079] When the temperature of the battery swap pack 22 is higher than the first set threshold, the air cooling system is turned on, and the cold air in the external environment passes through the vents, the guide groove 521 of the outer shell of the battery swap pack 22, and enters the battery compartment 21 to cool the battery swap pack 22, and then the heat dissipation fan 51 is used to guide the wind to the external environment. The cold air in the external environment can be used to dissipate heat, which can reduce the energy consumption of the charging and swapping energy storage cabinet.

[0080] It should be noted that the guide groove 521 can be set on each surface of the battery swap pack 22 to increase the heat dissipation area of ​​the battery swap pack 22.

[0081] Optionally, the outer shell material of the battery swap pack 22 is a material with high thermal conductivity, high strength and low density.

[0082] In this embodiment, the outer shell of the battery swap package 22 is a metal shell, and the battery is sealed in the metal shell. When the battery swap package 22 is sprayed with water, the outer shell can prevent the sprayed water from entering the battery swap package 22.

[0083] Optionally, refer to Figure 2 , the guide groove 521 extends from the top to the bottom of the shell.

[0084] refer to Figure 2 , exemplarily, the guide groove 521 is in a straight line shape.

[0085] Exemplarily, the guide groove 521 is in the shape of a fin.

[0086] In this embodiment, the guide groove 521 can extend from the top to the bottom of the housing, thereby increasing the heat dissipation area of ​​the battery pack 22. In addition, the shape of the guide groove 521 can be linear, which is easy to manufacture and reduces process costs; the shape of the guide groove 521 can also be fin-shaped, which can further increase the heat dissipation area.

[0087] Optionally, refer to Figure 3 A plurality of heat dissipation fins 52 are arranged on the metal shell of the battery swap package 22. A guide groove 521 is formed between two adjacent heat dissipation fins. A guide plate 522 is arranged at one end of the heat dissipation fin 52 away from the battery swap package 22. A gap is arranged between adjacent guide plates 522.

[0088] In this embodiment, the heat of the outer shell of the battery swap pack 22 can be transferred to the heat dissipation fins 52 more quickly and evenly, and the heat dissipation fins 52 increase the heat dissipation area of ​​the battery swap pack 22. The guide grooves 521 formed between two adjacent heat dissipation fins can promote the convection of cold air and further improve the heat dissipation effect. The guide plates 522 of the heat dissipation fins 52 can limit the guide path of the cold air. In addition, gaps are provided between adjacent guide plates 522, which can enable the cold air to flow in the internal space of the battery compartment 21 and reduce wind resistance.

[0089] Optionally, the first set threshold is not less than 25°C and not more than 30°C. The second set threshold is not less than 40°C and not more than 45°C. The third set threshold is not less than 25°C; the fourth set threshold is not more than 10°C; the fifth set threshold is not more than 5°C; and the sixth set threshold is not more than 15°C.
