Description

Technical Field

[0001] The present application relates to the field of battery cooling technology for battery swapping, and in particular to a battery cooling device and a battery swapping station. Background Art

[0002] The battery swap station is used to replace the battery in the battery swap vehicle and to charge the battery pack. During the charging process of the battery pack at the battery swap station, the battery pack needs to be cooled to avoid a rapid increase in the temperature of the battery pack during the charging process, which affects the service life of the battery pack. However, the water pressure when cooling the battery pack in the battery swap station is often greater than the water pressure in the vehicle to be replaced. As a result, when the battery swap vehicle undergoes multiple battery pack replacements, the antifreeze level in the water tank in the vehicle will increase, while the antifreeze level in the battery swap station will decrease. When the antifreeze level in the water tank in the vehicle increases, the antifreeze in the vehicle is likely to overflow, and the overflowed liquid will damage the relevant electrical components of the passenger car, thereby reducing the service life of the battery pack and affecting the efficiency and safety of normal driving.

[0023] Hereinafter, embodiments will be described with reference to the accompanying drawings, which do not limit the disclosure described in the claims in any way.

[0024] See also Figure 1 , the following combination Figure 1 A battery cooling device provided in an embodiment of the present application is described in detail.

[0025] The present application embodiment provides a battery cooling device, such as Figure 1 As shown, the battery cooling device includes a hydraulic detection component 1 and a refrigeration component.

[0026] Among them, the refrigeration component includes a refrigeration mechanism 21, a liquid outlet pipe 22 and a liquid inlet pipe 23, the liquid inlet end of the liquid outlet pipe 22 and the liquid outlet end of the liquid inlet pipe 23 are both connected to the refrigeration mechanism 21, and the liquid outlet end of the liquid outlet pipe 22 and the liquid inlet end of the liquid inlet pipe 23 are both connected to the battery pack 3 to be replaced; the hydraulic detection component 1 includes a hydraulic detection component 11 and a hydraulic adjustment component 12, the hydraulic detection component 11 and the hydraulic adjustment component 12 are arranged on the liquid outlet pipe 22, and the hydraulic detection component 11 is arranged at one end close to the battery pack 3 to be replaced, the hydraulic detection component 11 is used to detect the hydraulic value in the battery pack 3 to be replaced, and the hydraulic adjustment component 12 is used to relieve the pressure of the battery pack 3 to be replaced when the hydraulic value meets the preset pressure condition.

[0027] In an embodiment of the present application, the refrigeration mechanism 21 is used to cool down the battery pack 3 to be replaced through the liquid outlet pipe 22 and the liquid inlet pipe 23. Specifically, the refrigeration mechanism 21 can be used to cool down the liquid in the liquid inlet pipe 23, and the liquid cooled by the refrigeration mechanism 21 flows back to the battery pack 3 to be replaced through the liquid outlet pipe 22, so as to achieve cooling of the battery pack 3 to be replaced.

[0028] In some embodiments, the hydraulic detection component 11 is arranged at one end of the liquid outlet pipe 22 close to the battery pack 3 to be replaced, so that the hydraulic pressure in the battery pack 3 to be replaced can be detected by the hydraulic detection component 11. In a specific embodiment, the hydraulic detection component 11 can be a pressure sensor, and the hydraulic adjustment component 12 is arranged on the liquid outlet pipe 22, so that when the hydraulic adjustment component 12 is used to relieve the pressure of the battery pack 3 to be replaced, the liquid in the battery pack 3 to be replaced during the pressure relief can be transported by part of the liquid outlet pipe 22, so as to simplify the internal pipelines and reduce production costs.

[0029] It should be noted that the hydraulic detection component 11 and the hydraulic adjustment component 12 can both be connected to the controller so that the controller can be used to control the states of the hydraulic detection component 11 and the hydraulic adjustment component 12. Further, when the hydraulic detection component 11 is used to detect the hydraulic value in the battery pack 3 to be replaced, the detection information can be transmitted to the controller so that the controller can be used to determine whether the hydraulic value meets the preset pressure condition. When the hydraulic value meets the preset pressure condition, the hydraulic adjustment component 12 is controlled to relieve the pressure of the battery pack 3 to be replaced so as to reduce the hydraulic value in the battery pack 3 to be replaced. This can avoid the situation where the antifreeze liquid level in the water tank in the vehicle increases when the battery pack 3 to be replaced is replaced on the vehicle due to the hydraulic value in the battery pack 3 to be replaced being too high.

[0030] In actual applications, the preset pressure condition may be that the hydraulic pressure value in the battery pack 3 to be replaced is greater than normal pressure, or the hydraulic pressure value in the battery pack 3 to be replaced is greater than the initial entry hydraulic pressure value of the battery pack 3 to be replaced.

[0031] In some embodiments, Figure 1 As shown, the number of battery packs 3 to be replaced is 4. It should be noted that the number of battery packs 3 to be replaced can also be 5, 6 or 7, etc., and the number of battery packs 3 to be replaced is not specifically limited here.

[0032] In a specific embodiment, Figure 1 As shown, the hydraulic detection component 1 also includes a pressure relief pipe 13 and a liquid collecting part 14. One end of the pressure relief pipe 13 is connected to the hydraulic adjustment part 12, and the other end of the pressure relief pipe 13 is connected to the liquid collecting part 14. The pressure relief pipe 13 is used to transport the liquid in the battery pack 3 to be replaced to the liquid collecting part 14.

[0033] In the embodiment of the present application, the liquid collecting component 14 can be a liquid replenishing tank, and the output end of the liquid collecting component 14 is connected to the buffer tank 214 in the refrigeration mechanism 21, so that the liquid collecting component 14 can transfer the collected liquid to the buffer tank 214, thereby realizing the recycling of the liquid.

[0034] In a specific embodiment, the hydraulic adjusting component 12 can connect the liquid outlet pipe 22 and the pressure relief pipe 13 when the hydraulic value meets the preset pressure condition. Further, when the liquid outlet pipe 22 and the pressure relief pipe 13 are in a connected state, the pressure relief pipe 13 can transport the liquid in the battery pack 3 to be replaced to the liquid collecting component 14 to reduce the hydraulic value in the battery pack 3 to be replaced, thereby realizing the pressure relief process of the battery pack 3 to be replaced.

[0035] It should be noted that when the hydraulic pressure in the battery pack 3 to be replaced is detected by the hydraulic detection component 11, the refrigeration mechanism 21 is in a state of stopping cooling the battery pack 3 to be replaced. It can be understood that when the battery pack 3 to be replaced is in a fully charged state and the battery pack 3 to be replaced is still connected to the charging compartment in the battery swap station, that is, before unplugging the battery pack 3 to be replaced, the hydraulic pressure in the battery pack 3 to be replaced is detected by the hydraulic detection component 11, and then when it is necessary to relieve the pressure of the battery pack 3 to be replaced, the excess liquid can be discharged into the liquid collecting component 14 with the help of the liquid outlet pipe 22 and the pressure relief pipe 13 between the hydraulic adjustment component 12 and the battery pack 3 to be replaced, so as to utilize part of the original cooling pipeline to relieve the pressure of the battery pack 3 to be replaced, and the discharged liquid can also flow back to the buffer tank 214, thereby effectively reducing energy consumption and realizing liquid recycling.

[0036] In actual applications, the liquid in the battery pack 3 to be replaced is a liquid for cooling. In a specific implementation, the liquid in the battery pack 3 to be replaced can be water or coolant.

[0037] In a specific embodiment, the hydraulic adjustment member 12 includes a three-way regulating valve, and a pressure relief end of the three-way regulating valve is connected to the pressure relief pipeline 13 .

[0038] In the embodiment of the present application, the three-way regulating valve can be a three-way ball valve, and then by connecting the pressure relief end of the three-way ball valve with the pressure relief pipe 13, the liquid outlet pipe 22 between the hydraulic adjusting component 12 and the battery pack 3 to be replaced can be connected to the pressure relief pipe 13, thereby achieving pressure relief of the battery pack 3 to be replaced. It should be noted that after the pressure relief, the hydraulic value in the battery pack 3 to be replaced is equal to the normal pressure, or the hydraulic value in the battery pack 3 to be replaced is equal to the initial inbound hydraulic value of the battery pack 3 to be replaced.

[0039] It should be noted that when the hydraulic pressure in the battery pack 3 to be replaced is detected by the hydraulic detection component 11, the three-way regulating valve can control the liquid in the liquid outlet pipe 22 to be in a non-circulating state, and then the liquid outlet pipe 22 and the pressure relief pipe 13 between the hydraulic adjustment component 12 and the battery pack 3 to be replaced can be used to relieve the pressure of the battery pack 3 to be replaced.

[0040] In a specific embodiment, Figure 1As shown, a two-way regulating valve 24 is provided on the liquid inlet pipeline 23, and the two-way regulating valve 24 is used to control the liquid inlet pipeline 23 to be in a conducting state or a disconnecting state.

[0041] Specifically, the two-way regulating valve 24 can be a two-way ball valve, which can control the on-off of the liquid inlet pipe 23. It should be noted that when the hydraulic pressure in the battery pack 3 to be replaced is detected by the hydraulic detection component 11, the two-way regulating valve 24 is in a disconnected state. At this time, the refrigeration mechanism 21 is in a state of stopping cooling the battery pack 3 to be replaced.

[0042] Furthermore, a manual ball valve 15 is provided on both the liquid inlet pipe 23 and the liquid outlet pipe 22. Figure 1 As shown, the manual ball valve 15 on the liquid inlet pipe 23 is arranged on the side of the two-way regulating valve 24 away from the battery pack 3 to be replaced, and the manual ball valve 15 on the liquid outlet pipe 22 is arranged on the side of the three-way regulating valve away from the battery pack 3 to be replaced. Specifically, the manual ball valve 15 is arranged to facilitate the operator to manually adjust the on-off of the liquid inlet pipe 23 and the liquid outlet pipe 22.

[0043] In a specific embodiment, Figure 1 As shown, the refrigeration mechanism 21 includes a first circulating refrigeration pipeline 211, a second circulating refrigeration pipeline 212 and a heat exchanger 213, both ends of the first circulating refrigeration pipeline 211 are respectively connected to the heat exchanger 213, and both ends of the second circulating refrigeration pipeline 212 are respectively connected to the heat exchanger 213.

[0044] In an embodiment of the present application, the first circulating refrigeration pipeline 211 is used to cool and cool the liquid flowing through the heat exchanger 213, and the second circulating refrigeration pipeline 212 is also used to cool and cool the liquid flowing through the heat exchanger 213, wherein the refrigeration power of the first circulating refrigeration pipeline 211 for cooling and cooling the liquid flowing through the heat exchanger 213 may be equal to or unequal to the refrigeration power of the second circulating refrigeration pipeline 212 for cooling and cooling the liquid flowing through the heat exchanger 213. When the refrigeration power of the first circulating refrigeration pipeline 211 for cooling and cooling the liquid flowing through the heat exchanger 213 is equal to the refrigeration power of the second circulating refrigeration pipeline 212 for cooling and cooling the liquid flowing through the heat exchanger 213, redundant refrigeration can be achieved while increasing the overall refrigeration capacity, thereby avoiding the situation where the circulating refrigeration process is terminated when any of the circulating refrigeration pipelines stops working.

[0045] Further, when the refrigeration power of the first circulating refrigeration pipeline 211 for cooling the liquid flowing through the heat exchanger 213 is not equal to the refrigeration power of the second circulating refrigeration pipeline 212 for cooling the liquid flowing through the heat exchanger 213, it can be understood that the overall refrigeration power is divided into two gears, which can increase the overall cooling capacity on the one hand and meet the demand for small cooling capacity on the other hand.

[0046] In a specific embodiment, Figure 1 As shown, the first circulating refrigeration pipeline 211 includes a first condenser 2111, a first converter 2112 and a first compressor 2113, and the first converter 2112, the first condenser 2111, the first compressor 2113 and the heat exchanger 213 are connected in series in sequence.

[0047] Specifically, the first compressor 2113 is used to compress the refrigerant to form a high-temperature and high-pressure refrigerant, and transmit the high-temperature and high-pressure refrigerant to the first condenser 2111. After being processed by the first condenser 2111, a medium-temperature and high-pressure refrigerant is formed. The medium-temperature and high-pressure refrigerant is transmitted to the heat exchanger 213. The medium-temperature and high-pressure refrigerant transmitted to the heat exchanger 213 can then be used to perform heat exchange on the liquid flowing through the heat exchanger 213 to achieve a cooling operation. However, the refrigerant after the heat exchange flows into the first compressor 2113 to achieve a circulating refrigeration effect.

[0048] In some embodiments, the first converter 2112 is used to transfer the heat generated in the first circulating refrigeration pipeline 211, control the operating temperature of the first circulating refrigeration pipeline 211, and protect the components in the first circulating refrigeration pipeline 211 from overheating, thereby ensuring the normal operation of the first circulating refrigeration pipeline 211 and extending its service life.

[0049] Furthermore, if Figure 1 As shown, the second circulating refrigeration pipeline 212 includes a second condenser 2121, a second converter 2122 and a second compressor 2123, and the second converter 2122, the second condenser 2121, the second compressor 2123 and the heat exchanger 213 are connected in series in sequence.

[0050] Specifically, the second compressor 2123 is used to compress the refrigerant to form a high-temperature and high-pressure refrigerant, and transmit the high-temperature and high-pressure refrigerant to the second condenser 2121. After being processed by the second condenser 2121, a medium-temperature and high-pressure refrigerant is formed. The medium-temperature and high-pressure refrigerant is transmitted to the heat exchanger 213. The medium-temperature and high-pressure refrigerant transmitted to the heat exchanger 213 can then be used to perform heat exchange on the liquid flowing through the heat exchanger 213 to achieve a cooling operation. However, the refrigerant after the heat exchange flows into the second compressor 2123 to achieve a circulating refrigeration effect.

[0051] In some embodiments, the second converter 2122 is used to transfer the heat generated in the second circulating refrigeration pipeline 212, control the operating temperature of the second circulating refrigeration pipeline 212, and protect the components in the second circulating refrigeration pipeline 212 from overheating, thereby ensuring the normal operation of the second circulating refrigeration pipeline 212 and extending its service life.

[0052] In a specific embodiment, Figure 1 As shown, the refrigeration mechanism 21 also includes a buffer box 214, a first liquid outlet of the buffer box 214 is connected to the heat exchanger 213 through a first connecting pipe, a second liquid outlet of the buffer box 214 is connected to the battery pack 3 to be replaced through a liquid outlet pipe 22, a first liquid inlet of the buffer box 214 is connected to the heat exchanger 213 through a second connecting pipe, and a second liquid inlet of the buffer box 214 is connected to the battery pack 3 to be replaced through a liquid inlet pipe 23.

[0053] In the embodiment of the present application, the buffer box 214 is arranged between the heat exchanger 213 and the battery pack 3 to be replaced, so that the buffer box 214 can be used to perform heat exchange on the battery pack 3 to be replaced, thereby avoiding the frequent start and stop of the cooling device due to rapid temperature changes, thereby improving the service life of the compressor.

[0054] In a specific embodiment, the buffer tank 214 can be a 200L buffer water tank, and the heat exchanger 213 is used to control the liquid temperature in the buffer tank 214 to be in a constant temperature state, so that the buffer tank 214 can exchange heat with the battery pack 3 to be replaced, thereby avoiding direct heat exchange to cause rapid temperature changes and cause the cooling device to start and stop frequently.

[0055] In some embodiments, Figure 1 As shown, a ring pump 216 is provided on the first connecting pipeline and the liquid inlet pipeline 23. By providing the ring pump 216, the ring pump 216 can be used to promote the flow of liquid in the first connecting pipeline and the liquid in the liquid inlet pipeline 23 to improve the cooling efficiency.

[0056] In a specific embodiment, Figure 1 As shown, an electric heater 215 is provided on the second connecting pipeline, and the electric heater 215 is used to adjust the temperature value of the liquid in the second connecting pipeline.

[0057] In the embodiment of the present application, a heater 215 is provided on the second connecting pipeline so that the temperature value of the liquid in the second connecting pipeline can be adjusted by the heater 215 to achieve the purpose of multi-temperature adjustment.

[0058] The above embodiments of the present application have the following beneficial effects:

[0059] The present application provides a hydraulic detection component including a hydraulic detection component and a hydraulic adjustment component, and a refrigeration component including a refrigeration mechanism, a liquid outlet pipe and a liquid inlet pipe, so that while the refrigeration component is used to cool down the battery pack to be replaced, the hydraulic value in the battery pack to be replaced can be detected by the hydraulic detection component arranged on the liquid outlet pipe. Then, when the hydraulic value meets the preset pressure condition, the hydraulic adjustment component is controlled to relieve the pressure of the battery pack to be replaced to reduce the hydraulic value in the battery pack to be replaced, thereby avoiding the situation where the antifreeze liquid level in the water tank in the vehicle increases when the battery pack to be replaced is replaced on the vehicle due to the hydraulic value in the battery pack being too high.

[0060] An embodiment of the present application also provides a battery swap station, which includes the battery cooling device as described above. Since the battery swap station has all the technical features of the above-mentioned battery cooling device, the battery swap station in this embodiment should also have the same technical effects, which will not be repeated here.
