DETAILED DESCRIPTION

[0044] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0045] In the prior art, the distance between the manufacturing site and the use site of the battery is relatively far. When transporting the battery from the manufacturing site to the use site, due to the complex changes in ambient temperature, humidity and altitude between the manufacturing site and the use site of the battery, when the ambient humidity is high and the temperature difference between the ambient temperature and the internal temperature of the battery is large, condensation will occur inside the battery. Condensation can easily cause rust and short circuit of the internal parts of the battery, and can easily cause mold to grow inside the battery, thereby affecting the reliability of the battery, causing safety hazards to the battery, and reducing the service life of the battery.

[0046] Based on this, an embodiment of the present application provides an anti-condensation system, including an air intake device, a filtering device, a drying device and a pressure diffuser. External air enters the filtering device through the air intake device, and impurities or water droplets in the air are filtered by the filtering device. Then the air enters the drying device, and the air is dried by the drying device. Then the dry air enters the pressure diffuser, and the dry air is pressurized by the pressure diffuser to force the dry air to enter the battery device, so as to reduce the humidity in the battery device, thereby preventing condensation from occurring in the battery device.

[0047] The embodiments of the present application are described below with reference to the accompanying drawings.

[0048] Reference Figures 1 to 7 The anti-condensation system provided in the embodiment of the present application is used in a transport device, and the transport device is used to transport a battery device 10, and the battery device 10 is located in a cabin 20 of the transport device. The anti-condensation system includes: an air intake device 100, a filter device 200, a drying device 300, and a pressure diffuser 400. The air intake device 100 is used to communicate with the external air.

[0049] The filter device 200 is connected to the air intake device 100 to filter impurities in the air, or to filter impurities and water droplets in the air. The drying device 300 is connected to the end of the filter device 200 away from the air intake device 100 to dry the air filtered by the filter device 200. One end of the diffuser 400 is connected to the end of the dryer 300 away from the filter device 200, and the diffuser 400 is used to pressurize the air, and the other end of the diffuser 400 is used to communicate with the battery device 10.

[0050] The transport device may be a vehicle, the cabin 20 may be a cargo hold of the vehicle located behind the cockpit, and the cargo hold may be closed. There are multiple battery devices 10, each of which is sequentially arranged in the cabin 20. The battery device 10 may be a battery module or a battery cluster.

[0051] Exemplarily, the installation position of the air intake device 100 needs to be higher than the air intake of the battery device 10, so as to improve the air energy of the air intake of the battery device 10. Furthermore, the diffuser device 400 enters the cabin 20 through the air intake of the cabin 20 and communicates with the battery device 10, and the installation position of the air intake device 100 needs to be higher than the air intake of the cabin 20.

[0052] The filter device 200 includes a filter and a discharge mechanism, wherein the filter is used to filter impurities or large-sized water droplets in the air, and the discharge mechanism is used to discharge the impurities or large-sized water droplets filtered by the filter out of the filter device. The discharge mechanism can be arranged at the bottom of the filter device 200. For example, the discharge mechanism can adopt a one-way gravity drainage mechanism to discharge the water droplets out of the filter device by the gravity of the water droplets. Exemplarily, the filter can be a filter screen or a filter cloth.

[0053] The drying device 300 is disposed at the rear side of the filter device 200, and the air entering the drying device 300 is dried by the drying device 300 to prevent humid air from entering the battery device 10. Exemplarily, the drying device 300 may adopt a combination of one or more of an electric heating dehumidification drying method, a desiccant method, and a condensation dehumidification method.

[0054] In a specific implementation, external air enters the filter device 200 through the air intake device 100. After the impurities and large-sized water droplets in the air are filtered by the filter device 200, the air enters the drying device 300. After the drying device 300 dries the air, the dry air enters the diffuser device 400. The diffuser device 400 pressurizes the dry air to pressurize the air, thereby prompting the dry air to enter the battery device 10, thereby reducing the humidity in the battery device 10.

[0055] The anti-condensation system provided in the embodiment of the present application includes an air intake device 100, a filter device 200, a drying device 300 and a pressure diffuser 400. External air enters the filter device 200 through the air intake device 100, and impurities or water droplets in the air are filtered by the filter device 200. Then the air enters the drying device 300, and the air is dried by the drying device 300. Then the dry air enters the pressure diffuser 400, and the dry air is pressurized by the pressure diffuser 400, so as to force the dry air to enter the battery device 10, so as to reduce the humidity in the battery device 10, thereby preventing condensation from being generated in the battery device 10.

[0056] Reference Figure 1 , Figure 2 and Figure 3 In a specific implementation, the air intake device 100 has an air intake channel 110 , and the air intake channel 110 is used to communicate with the external air. The air intake channel 110 is connected to the filter device 200 .

[0057] By opening the air intake passage 110, external air can enter the system through the air intake device 100, and can flow into the filter device 200 through the air intake passage 110, so that the anti-condensation system starts to work. By closing the air intake passage 110, external impurities or rain and snow are prevented from entering the system through the air intake passage 110.

[0058] Reference Figure 2 and Figure 3 In some embodiments, the air intake device 100 includes a first cover body 120 and a second cover body 130, and the first cover body 120 and the second cover body 130 are respectively located on opposite sides of the air intake channel 110, and the first cover body 120 includes a fixed section 121 and a rotating section 122, and the fixed section 121 is rotatably connected to the rotating section 122, and the rotating section 122 rotates relative to the fixed section 121 to open or close the air intake channel 110.

[0059] Exemplarily, the fixed section 121 and the rotating section 122 are rotatably connected via a hinge portion 123 .

[0060] Furthermore, the hinged portion 123 may be a rotating shaft. The rotating shaft may be connected to a driving member, and the driving member drives the rotating shaft to rotate relative to the fixed section 121, and then the rotating shaft may drive the rotating section 122 to rotate relative to the fixed section 121. Thus, the rotating section 122 may rotate relative to the fixed section 121. The driving member may be an electric motor or the like.

[0061] Reference Figure 2 and Figure 3 In a specific implementation, the second cover body 130 has a limiting portion 131 , and the rotating section 122 rotates relative to the fixed section 121 to connect with the limiting portion 131 to close the air inlet channel 110 .

[0062] The rotating section 122 rotates relative to the fixed section 121, so that the end of the rotating section 122 away from the hinge 123 is connected to the limiting portion 131, so that the air inlet passage 110 is closed by the rotating section 122, thereby preventing external air from entering the air inlet passage 110. The rotating section 122 rotates relative to the fixed section 121, so that the end of the rotating section 122 away from the hinge 123 is not connected to the limiting portion 131, so that the air inlet passage 110 is in an open state, and external air can enter the air inlet passage 110 through the space between the rotating section 122 and the second cover 130.

[0063] Exemplarily, the limiting portion 131 is a limiting groove provided on a surface of the second cover body 130 facing the first cover body 120 , and a portion of the rotating section 122 is located in the limiting groove, so that the rotating section 122 is limited by the limiting groove.

[0064] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the diffuser device 400 has a diffuser air inlet 410 and a diffuser air outlet 420 that are connected. The diffuser air inlet 410 is connected to the drying device 300, and the diffuser air outlet 420 is used to connect to the battery device 10. The cross-sectional area of ​​the diffuser air inlet 410 is smaller than the cross-sectional area of ​​the diffuser air outlet 420.

[0065] The pressure diffuser 400 has a pressure diffuser channel, one end of the pressure diffuser channel is a pressure diffuser air inlet 410, and the other end is a pressure diffuser air outlet 420, and the pressure diffuser air inlet 410 and the pressure diffuser air outlet 420 are connected through the pressure diffuser channel. The cross-sectional area of ​​the pressure diffuser air inlet 410 is smaller than the cross-sectional area of ​​the pressure diffuser air outlet 420. According to Bernoulli's principle: when a fluid flows from a smaller cross-sectional area to a larger cross-sectional area, the flow rate decreases and the pressure increases. Therefore, the pressure of the air can be increased by the pressure diffuser 400, and the air can be prompted to enter the battery device 10.

[0066] Exemplarily, the pressure diffuser 400 includes an air inlet section, an expansion section and an air outlet section, wherein the expansion section connects the air inlet section and the air outlet section. The cross-sectional area of ​​the air inlet section is equal everywhere, the cross-sectional area of ​​the air outlet section is equal everywhere, and the cross-sectional area of ​​the air inlet section is smaller than the cross-sectional area of ​​the air outlet section. The cross-sectional area of ​​the expansion section gradually increases from one end close to the air inlet section to one end close to the air outlet section.

[0067] It can be understood that the shapes of the air inlet section and the air outlet section can be the same, for example, the shapes of the air inlet section and the air outlet section can both be circular or square.

[0068] Reference Figure 7 In a specific implementation, the anti-condensation system provided in the embodiment of the present application further includes a conveying device 500, which is used to connect the pressure diffuser 400 and the battery device 10, and the conveying device 500 is used to connect the battery device 10 with the outside of the cabin 20.

[0069] The dry air pressurized by the diffuser device 400 is transported to the battery device 10 through the transport device 500 , and the transport device 500 can transport the humid air flowing out of the battery device 10 to the outside of the cabin 20 .

[0070] Reference Figure 7 In some embodiments, the delivery device 500 includes an air intake manifold 510, an air outlet manifold 530, a plurality of air intake branches 520, and a plurality of air outlet branches 540. Each air intake branch 520 is connected to the air intake manifold 510, each air intake branch 520 is connected to each battery device 10, and the air intake manifold 510 is connected to the diffuser device 400. Each air outlet branch 540 is connected to the air outlet manifold 530, each air outlet branch 540 is connected to a battery, and the air outlet manifold 530 is connected to the outside of the cabin 20.

[0071] Among them, the air intake main pipe 510 is connected to the pressure diffuser outlet 420 of the pressure diffuser device 400, and the air intake branch pipe 520 is connected to the battery device 10 one by one. The dry air after pressure diffusion is delivered to each battery device 10 through the air intake main pipe 510 and the air intake branch pipe 520. The air outlet branch pipe 540 is connected to the battery device 10 one by one, and each air outlet branch pipe 540 is connected to the air outlet main pipe 530, so that the humid air in each battery device 10 can be discharged to the air outlet branch pipe 540 under the push of dry air, and converge to the air outlet main pipe 530 through each air outlet branch pipe 540, and finally discharged to the outside through the air outlet main pipe 530. In this way, the humid air in the battery device 10 can be removed, the humidity in the battery device 10 can be reduced, and condensation is not easy to be generated in the battery device 10.

[0072] Exemplarily, the air inlet branch pipe 520 and the air outlet branch pipe 540 are respectively connected to opposite sides of the battery device 10 , so that the dry air entering the battery device 10 through the air inlet branch pipe 520 pushes the wet air in the battery device 10 to be discharged to the air outlet branch pipe 540 .

[0073] In some embodiments, the transport device 500 further includes a one-way valve, which connects the main air outlet pipe 530 with the outside of the cabin 20 to prevent air from entering the battery device 10 through the main air outlet pipe 530 .

[0074] refer to Figure 7 In some embodiments, the conveying device 500 also includes a three-way valve 550 and a fan 560. The three-way valve 550 has an air inlet end 551, a first air outlet end 552 and a second air outlet end 553. The air inlet end 551 is connected to the air outlet main pipe 530, the first air outlet end 552 is connected to the external air through the fan 560, and the second air outlet end 553 is connected to the external air.

[0075] Exemplarily, the fan 560 may be an axial flow fan or a centrifugal fan, etc.

[0076] Specifically, when the transport equipment stops, the air inlet 551 and the first air outlet 552 are opened, and the second air outlet 553 is closed. The humid air discharged through the air outlet main pipe 530 can be drawn out through the air inlet 551 and the first air outlet 552 by the fan 560 .

[0077] When the transport equipment is running, the air inlet 551 and the second air outlet 553 are opened, and the first air outlet 552 is closed. The high-speed airflow generated when the transport equipment is running enables the wet air discharged through the air outlet manifold 530 to be discharged through the air inlet 551 and the second air outlet 553.

[0078] Reference Figure 7In a specific implementation, the anti-condensation system provided in the embodiment of the present application further includes a detection component 600 , which is used to be arranged in the cabin 20 , and the detection component 600 is used to detect the dew point temperature in the cabin 20 .

[0079] The dew point temperature in the cabin 20 is detected to determine whether the water vapor in the cabin 20 will condense into condensation according to the dew point temperature. The detection component 600 can be disposed on the inner wall of the cabin 20.

[0080] Specifically, the detection assembly 600 can also be used to detect the ambient temperature in the cabin 20. When the ambient temperature is greater than the dew point temperature, water vapor is not easy to condense into condensation. At this time, the battery device 10 does not need to be dehumidified, and the air intake device 100 is in a closed state. When the ambient temperature is less than or equal to the dew point temperature, water vapor is more likely to condense into condensation. When the ambient temperature is less than or equal to the dew point temperature, the air intake device 100 can be turned on to turn on the battery device transportation and anti-condensation system, thereby removing moisture from the battery device 10, reducing the humidity in the battery device 10, and preventing water vapor in the battery device 10 from condensing into condensation.

[0081] Reference Figure 1 and Figure 7 In a specific implementation, the anti-condensation system provided in the embodiment of the present application further includes a control device 700 , which is electrically connected to the air intake device 100 , and the control device 700 controls the opening or closing of the air intake device 100 .

[0082] Specifically, the control device 700 is electrically connected to the detection component 600, so that the control device 700 can control the opening of the air intake device 100 according to the dew point temperature.

[0083] In some examples, the control device 700 is also electrically connected to the three-way valve 550 and the fan 560. When the transport equipment stops, the control device 700 controls the air intake device 100 to open, controls the air intake end 551 and the first air outlet end 552 of the three-way valve 550 to open, and controls the second air outlet end 553 of the three-way valve 550 to close, so that the air intake end 551 is connected to the first air outlet end 552, and controls the fan 560 to open. When the transport equipment is traveling, the control device 700 controls the air intake device 100 to open, controls the air intake end 551 and the second air outlet end 553 of the three-way valve 550 to open, and controls the first air outlet end 552 to close, so that the air intake end 551 is connected to the second air outlet end 553.

[0084] On the basis of the above-mentioned embodiments, an embodiment of the present application provides a transportation device, including a device body and any one of the above-mentioned anti-condensation systems arranged on the device body.

[0085] The specific structure of the anti-condensation system has been described in detail in the above embodiments and will not be repeated here.

[0086] Exemplarily, the transport device may be a vehicle. The device body includes a cabin 20, and the cabin 20 is used to accommodate the battery device 10 so as to transport the battery device 10 through the transport device.

[0087] The transportation equipment provided in the embodiment of the present application has an anti-condensation system including an air intake device 100, a filter device 200, a drying device 300 and a pressure diffuser 400. External air enters the filter device 200 through the air intake device 100, and impurities or water droplets in the air are filtered by the filter device 200. Then the air enters the drying device 300, and the air is dried by the drying device 300. Then the dry air enters the pressure diffuser 400, and the dry air is pressurized by the pressure diffuser 400, so as to force the dry air to enter the battery device 10, so as to reduce the humidity in the battery device 10, thereby preventing condensation from being generated in the battery device 10.

[0088] Reference Figure 8 Based on the above embodiments, an embodiment of the present application provides an anti-condensation control method for controlling any anti-condensation system in the above embodiments, including:

[0089] S101: Acquire weather conditions and dew point temperature in the cabin 20;

[0090] The weather state refers to the current weather condition, which can be detected by the control device 700. The current dew point temperature in the cabin 20 can be detected by the detection component 600.

[0091] S102: Determine whether the weather condition is non-rain or snow, if yes, execute step S103, if no, execute step S101;

[0092] When the weather is rainy or snowy, the humidity of the outside air is relatively high. If the air intake device 100 is turned on, the outside humid air will enter the anti-condensation system, which may increase the humidity in the battery device 10. Therefore, when the weather is rainy or snowy, the air intake device 100 of the anti-condensation system remains closed.

[0093] When the weather condition is not raining or snowing, and the ambient temperature in the cabin 20 is lower than the dew point temperature, the battery device 10 needs to be dehumidified by the anti-condensation system.

[0094] S103: Determine whether the dew point temperature is greater than or equal to a preset temperature, if so, execute step S104, if not, execute step S101;

[0095] Among them, the preset temperature can be set according to the adaptability of ambient temperature and humidity.

[0096] When the dew point temperature is lower than the preset temperature, the water vapor in the air remains in the gaseous state and will not condense into condensation. Therefore, there is no need to dehumidify the battery device, and the air intake device 100 of the anti-condensation system can remain closed. When the dew point temperature is greater than or equal to the preset temperature, the water vapor in the air will condense into condensation more easily. Therefore, the battery device 10 needs to be dehumidified by the anti-condensation system.

[0097] S104: Control the air intake device 100 of the anti-condensation system to open.

[0098] Among them, when the weather condition is not raining or snowing, and the dew point temperature in the cabin 20 is greater than or equal to the preset temperature, the battery device 10 needs to be dehumidified by the anti-condensation system. At this time, the air intake device 100 of the anti-condensation system can be controlled to open, so that the external air can enter the anti-condensation system through the air intake device 100, and then the battery device 10 can be dehumidified by the anti-condensation system to prevent condensation from occurring in the battery device 10.

[0099] The anti-condensation control method provided in the embodiment of the present application determines whether condensation will be generated in the battery device 10 by judging the magnitude relationship between the dew point temperature and the preset temperature, and determines whether the weather condition is rain or snow to determine whether the humidity of the external air will cause an increase in condensation in the battery device 10. Therefore, when it is determined that condensation is more likely to be generated in the battery device 10 and the humidity in the air is low, the air intake device 100 can be controlled to be turned on, and then the battery device 10 can be dehumidified by the anti-condensation system to prevent condensation from being generated in the battery device 10.

[0100] In some embodiments, the humidity of the external air may also be obtained, and when the humidity of the external air is less than a preset humidity and the dew point temperature is greater than or equal to a preset temperature, the air intake device 100 is controlled to open.

[0101] The humidity of the external air can be detected by a hygrometer or a humidity sensor. The preset humidity can be adaptively set according to actual needs.

[0106] When the transport equipment is stopped, the humid air in the battery device 10 is discharged from the anti-condensation system in sequence through the outlet branch pipe 540, the outlet main pipe 530, the air inlet end 551, the first outlet end 552 and the fan 560. The fan 560 is used to extract the humid air from the anti-condensation system.

[0107] S203: If the transport equipment is in the driving state, the air inlet end 551 and the second air outlet end 553 of the three-way valve 550 are controlled to be connected.

[0108] Among them, when the transportation equipment is in a driving state, the high-speed airflow generated by the driving of the transportation equipment enters the anti-condensation system through the air intake device 100, and can enter the battery device 10 through the filtering device 200, the drying device 300, the pressure diffuser 400, the air intake manifold 510 and the air intake branch pipe 520 in sequence. The high-speed airflow can cause the humid air in the battery device 10 to be discharged from the anti-condensation system through the air outlet branch pipe 540, the air outlet manifold 530, the air intake end 551 and the second air outlet end 553 in sequence.
