[0041] Through the arrangement that the exhaust port 12 is arranged to selectively communicate with the first exhaust pipeline 52 or the second exhaust pipeline 53, when the humidity of the external environment is higher than the humidity in the battery compartment 1, the air in the battery compartment 1 is discharged into the air dehumidification chamber 2 through the first exhaust pipeline 52, and the air in the air dehumidification chamber 2 is dehumidified by the dehumidification device 3, when the humidity of the external environment is lower than the humidity in the battery compartment 1, the high humidity air in the battery compartment 1 is directly discharged to the external environment, avoiding the high humidity air in the battery compartment 1 being transported to the air dehumidification chamber 2 for dehumidification, so that the air with lower humidity always enters the air dehumidification chamber 2, thereby helping to save energy and further improving the dehumidification effect.

[0042] It should be noted that in actual application, the specific communication mode of the exhaust port 12 selectively communicating with the first exhaust pipeline 52 or the second exhaust pipeline 53 is not limited.

[0048] Through such arrangement, when the humidity in the battery compartment 1 is higher than that of the external environment, the air in the external environment is directly supplemented into the air dehumidification chamber 2 through the gas supplement pipeline 8, so that the air with high humidity in the battery compartment 1 can be avoided to be transported into the air dehumidification chamber 2, not only the energy can be saved, but also the air in the air dehumidification chamber 2 can be dehumidified more quickly, and the dehumidification efficiency is further improved.

[0049] It should be noted that in actual application, the skilled in the art can set up a gas supplement pipeline on the air dehumidification chamber 2 to make the air dehumidification chamber 2 communicate with the external environment, or can set up a gas supplement pipeline on the first exhaust pipeline 52 to make the air dehumidification chamber 2 communicate with the external environment, etc., and such flexible adjustment and change does not deviate from the principles and scope of the present application, and should be included in the protection scope of the present application.

[0052] The following two embodiments are introduced below.

[0053] Embodiment 1:

[0054] As shown in Figure 1As shown, one end of the air intake pipe 51 is connected to the outlet 22 of the air dehumidification chamber 2, and the other end of the air intake pipe 51 is connected to the air inlet 11 of the battery compartment 1. The dehumidification system also includes an air intake valve 511, which is installed on the air intake pipe 51 and used to control the opening and closing of the air intake pipe 51.

[0055] Example 2:

[0056] See next Figure 2 , Figure 2 This is a schematic diagram of the connection structure of another embodiment of the dehumidification system for battery compartment 1 of this utility model.

[0057] like Figure 2 As shown, the dehumidification system of this utility model also has an air storage chamber 41, wherein the outlet 22 of the air dehumidification chamber 2 is connected to the air storage chamber 41 so that the dehumidified air in the air dehumidification chamber 2 is stored in the air storage chamber 41. One end of the air inlet pipe 51 is connected to the air storage chamber 41, and the other end of the air inlet pipe 51 is connected to the air inlet 11 of the battery compartment 1. The air inlet valve 511 is provided on the air inlet pipe 51 and is used to control the opening and closing of the air inlet pipe 51.

[0058] With this setup, the dehumidified dry air in the dehumidification chamber 2 can be stored in the air storage chamber 41. When dehumidification is needed in the battery compartment 1, the dry air in the air storage chamber 41 can be directly transported to the battery compartment 1. At the same time, the humid air in the battery compartment 1 is transported to the dehumidification chamber 2. This avoids the humid air from the battery compartment 1 from mixing with the low-humidity air that is about to be transported to the battery compartment 1, which would result in the air transported to the battery compartment 1 having a higher humidity, thereby further improving the dehumidification effect.

[0059] It should be noted that, in practical applications, those skilled in the art can form an air storage cavity 41 within the air dehumidification chamber 2. For example, a partition plate can be installed within the air dehumidification chamber 2, dividing the air dehumidification chamber 2 into an air dehumidification cavity and an air storage cavity 41. The dehumidification device 3 is used to dehumidify the air within the air dehumidification cavity. After dehumidification is completed, the air within the air dehumidification cavity enters the air storage cavity 41 for storage. Alternatively, an air storage chamber 4 and a conveying pipe 7 can be installed, forming the air storage cavity 41 within the air storage chamber 4. One end of the conveying pipe 7 is connected to the air dehumidification chamber 2, and the other end of the conveying pipe 7 is connected to the air storage cavity 41, facilitating the storage of the dehumidified air within the air dehumidification chamber 2 in the air storage cavity 41. Such adjustments and changes to the specific configuration of the air storage cavity 41 do not deviate from the principles and scope of this utility model and should be included within the protection scope of this utility model.

[0060] Preferably, such as Figure 2The utility model discloses a dehumidification system, which comprises a battery compartment 1, an air dehumidification chamber 2 and a temperature adjusting device, wherein the battery compartment 1 is used for storing batteries, the air dehumidification chamber 2 is used for dehumidifying air, and the temperature adjusting device is used for adjusting the temperature of the air in the air dehumidification chamber 2.

[0061] By such a setting, compared with the form of forming the air storage cavity 41 in the air dehumidification chamber 2, by setting the air storage chamber 4 and the conveying pipe 7 and forming the air storage cavity 41 in the air storage chamber 4, the space in the air dehumidification chamber 2 can be avoided from being affected due to the setting of the air storage cavity 41, thereby helping to increase the dehumidification space in the air dehumidification chamber 2, and at the same time, more dry air can be stored for use, and the dehumidification capacity of the dehumidification system is greatly improved.

[0062] It should be noted that in actual application, the specific setting form of the air dehumidification chamber 2 is not limited in the utility model, for example, the air dehumidification chamber 2 can be directly set as one end being the inlet 21 and the other end being the outlet 22, or a partition plate can be arranged in the air dehumidification chamber 2, the partition plate separates the air dehumidification chamber 2 into air passages, wherein one end of the air passages is in communication with the inlet 21 of the air dehumidification chamber 2, and the other end of the air passages is in communication with the outlet 22 in the air dehumidification chamber 2, and the like, and the adjustment and change of the specific setting form of the air dehumidification chamber 2 do not deviate from the principles and scope of the utility model, and should be included in the protection scope of the utility model.

[0063] Preferably, a partition plate (not shown in the figure) is arranged in the air dehumidification chamber 2, the partition plate separates the air dehumidification chamber 2 into at least two air passages, wherein one end of the air passages is in communication with the inlet 21 of the air dehumidification chamber 2, and the other end of the air passages is in communication with the outlet 22 of the air dehumidification chamber 2.

[0064] By such a setting, when the dry air in the air dehumidification chamber 2 after dehumidification is conveyed into the battery compartment 1, the air in the air dehumidification chamber 2 can flow along the air passages as much as possible, thereby avoiding the mixing of the dry air in the air dehumidification chamber 2 and the wet air conveyed into the air dehumidification chamber 2 as much as possible, and further avoiding the influence on the air humidity conveyed into the battery compartment 1.

[0065] Preferably, the dehumidification system of the utility model further comprises a temperature adjusting device (not shown in the figure), the temperature adjusting device is used for adjusting the temperature of the air in the air dehumidification chamber 2, so that the temperature of the dry air conveyed into the battery compartment 1 approaches the temperature in the battery compartment 1.

[0066] By setting the temperature adjusting device, the air in the air dehumidification chamber 2 can be heated or cooled before being delivered into the battery compartment 1, so that the temperature of the air to be delivered into the battery compartment 1 is adapted to the temperature of the air in the battery compartment 1, thereby avoiding that the temperature of the battery compartment 1 fluctuates too much due to the too large difference between the temperature of the air in the air dehumidification chamber 2 and the temperature of the air in the battery compartment 1.

[0067] It should be noted that, in practical applications, the temperature adjusting device can be set as an air conditioner, or the temperature adjusting device can be set as including a heating component and a refrigeration component, wherein the heating component is used for heating the air in the air dehumidification chamber 2, and the refrigeration component is used for cooling the air in the air dehumidification chamber 2, and the like, and the adjustment and change of the specific setting type of the temperature adjusting device do not deviate from the principles and scope of the present application, and should be included in the protection scope of the present application.

[0068] Preferably, the temperature adjusting device is an air conditioner.

[0069] By setting the temperature adjusting device as an air conditioner, the air in the air dehumidification chamber 2 can be dehumidified, and the air in the air dehumidification chamber 2 after dehumidification can be temperature-adjusted, thereby making the structure of the dehumidification system simpler.

[0070] It should be noted that, when the dehumidification device 3 is an air conditioner, the temperature adjusting device is not required.

[0071] Preferably, the dehumidification system of the present application further comprises an air inlet shunt component 6, wherein the air inlet shunt component 6 is in communication with the air inlet 11, and the air inlet shunt component 6 is used for dispersing the air entering into the battery compartment 1 from the air inlet 11 to different positions in the battery compartment 1.

[0072] By setting the air inlet shunt component 6, the dry air after dehumidification can be delivered to different positions in the battery compartment 1 through the air inlet shunt component 6, thereby making the dry air enter into the battery compartment 1 more uniformly, and avoiding that the flow field in the battery compartment 1 is uneven.

[0073] It should be noted that, in practical applications, the present application does not make any limitation on the specific setting type of the air inlet shunt component 6, as long as the air delivered into the battery compartment 1 can be shunted to different positions in the battery compartment 1.

[0074] In one specific embodiment, as shown in Figure 1 and Figure 2 the air inlet shunt component 6 comprises a plurality of shunt pipes 61, one end of each of the shunt pipes 61 is in communication with the air inlet 11, and the other end of each of the shunt pipes 61 is spaced apart in the battery compartment 1.

[0075] It should be noted that the shunt pipes 61 can be spaced apart in the horizontal direction in the battery compartment 1, or the shunt pipes 61 can be spaced apart in the vertical direction in the battery compartment 1, or the shunt pipes 61 can be spaced apart in the horizontal direction and the vertical direction in the battery compartment 1.

[0076] In another specific embodiment, the air inlet shunt member 6 comprises a shunt pipe which is in communication with the air inlet 11 and is provided with a plurality of shunt holes (not shown in the figure) which are spaced apart on the shunt pipe.

[0077] Preferably, the shunt member comprises a plurality of shunt pipes 61, one end of each of the shunt pipes 61 being in communication with the air inlet 11, and the other end of each of the shunt pipes 61 being spaced apart in the battery compartment 1.

[0078] It should be noted that in actual application, the person skilled in the art can set the dehumidification system to correspond to only one battery compartment 1, or can set the dehumidification system to correspond to a plurality of battery compartments 1, and the dehumidification system is used to dehumidify different battery compartments 1, etc., and such adjustment and change of the number of battery compartments 1 to which the dehumidification system is applicable do not deviate from the principles and scope of the present application, and should be included in the protection scope of the present application.

[0079] Preferably, as shown in Figure 1 and Figure 2 , the number of battery compartments 1 is a plurality, the number of first exhaust pipes 52 is a plurality and is arranged in one-to-one correspondence with the battery compartments 1, the number of air inlet pipes 51 is a plurality and is arranged in one-to-one correspondence with the battery compartments 1, and the exhaust port 12 of each battery compartment 1 is in communication with the inlet 21 of the air dehumidification chamber 2 through the first exhaust pipe 52, and the outlet 22 of the air dehumidification chamber 2 is in communication with the air inlet 11 of each battery compartment 1 through the air inlet pipe 51.

[0080] Through such a setting, the dehumidification system can dehumidify a plurality of battery compartments 1, improve the dehumidification capacity, and greatly reduce the cost.

[0081] Exemplarily, the number of battery compartments 1 is 3, and the number of first exhaust pipes 52 and air inlet pipes 51 is also 3.

[0082] It should be noted that in actual application, the person skilled in the art can set only part of the exhaust ports 12 of the battery compartments 1 to be selectively in communication with the first exhaust pipe 52 or the second exhaust pipe 53, set the exhaust ports 12 of the remaining battery compartments 1 to be directly in communication with the first exhaust pipe 52, or can set the exhaust ports 12 in each battery compartment 1 to be selectively in communication with the first exhaust pipe 52 or the second exhaust pipe 53, etc., and such flexible adjustment and change do not deviate from the principles and scope of the present application, and should be included in the protection scope of the present application.

[0083] Preferably, as shown in Figure 1 and Figure 2 The number of the second exhaust pipelines 53 is multiple and is arranged one-to-one with the battery compartments 1, and the exhaust port 12 in each battery compartment 1 is arranged to be selectively communicated with the first exhaust pipeline 52 or the second exhaust pipeline 53.

[0084] It should be noted that in actual application, the dew point temperature in the battery compartment 1 can be acquired first, and then the dry air is selectively delivered into the battery compartment 1 according to the dew point temperature and the temperature of the coolant in the battery compartment 1, or the actual humidity in the battery compartment 1 can be acquired, and then the dry air is selectively delivered into the battery compartment 1 according to the actual humidity and the preset humidity, and the like, and such flexible adjustment and change does not deviate from the principles and scope of the present application, and should be included in the protection scope of the present application.

[0085] Preferably, the dew point temperature Td in the battery compartment 1 and the temperature T0 of the coolant in the battery compartment 1 are acquired first, and then the dry air is selectively delivered into the battery compartment 1 according to the dew point temperature Td and the temperature T0 of the coolant.

[0086] Specifically, if Td < T0, the dry air is delivered into the battery compartment 1;

[0087] If Td ≥ T0, the dry air is not delivered into the battery compartment 1.

[0088] Through such arrangement, when Td < T0, it indicates that there is a risk of condensation in the battery compartment 1, and at this time, the dry air needs to be delivered into the battery compartment 1 to avoid condensation, and when Td ≥ T0, it indicates that there is no risk of condensation in the battery compartment 1, and at this time, the dry air does not need to be delivered into the battery compartment 1 to avoid wasting energy.

[0089] Specifically, the temperature sensor is arranged on the coolant pipeline to acquire the temperature T0 of the coolant.

[0090] It should be noted that it is not limited to acquiring the dew point temperature in the battery compartment 1 first, and then selectively delivering the dry air into the battery compartment 1 according to the dew point temperature and the temperature of the coolant in the battery compartment 1, or the actual humidity in the battery compartment 1 can be acquired, and then the dry air is selectively delivered into the battery compartment 1 according to the actual humidity and the preset humidity, and the like, and such flexible adjustment and change does not deviate from the principles and scope of the present application, and should be included in the protection scope of the present application.

[0091] It also needs to be explained that in practical application, the specific acquisition mode of the dew point temperature Td is not limited, for example, the relative humidity and temperature in the battery compartment 1 can be acquired, and the dew point temperature Td is calculated according to the formula, or the relative humidity and temperature in the battery compartment 1 can be acquired, and the dew point temperature Td is acquired by table lookup, etc., and such adjustment and change of the dew point temperature Td does not deviate from the principles and scope of the present application, and should be included in the protection scope of the present application.

[0092] Preferably, as shown in Figure 1 and Figure 2 Before the dry air is delivered into the battery compartment 1, the actual humidity Hs in the battery compartment 1 and the external environment humidity Hw are acquired; according to the actual humidity Hs and the external environment humidity Hw, the exhaust port 12 is selectively communicated with the first exhaust pipeline 52 or the second exhaust pipeline 53.

[0093] Through such a setting, according to the actual humidity in the battery compartment 1 and the humidity of the external environment, the air with higher humidity in the battery compartment 1 is selectively exhausted into the air dehumidification chamber 2 through the first exhaust pipeline 52 or exhausted to the external environment through the second exhaust pipeline 53, so that the connection mode of the exhaust port 12 of the battery compartment 1 can be reasonably switched, and the air with lower humidity is always delivered into the air dehumidification chamber 2 for dehumidification, thereby the energy can be saved more.

[0094] Specifically, the humidity sensor is arranged in the battery compartment 1 to acquire the actual humidity Hs in the battery compartment 1, and the humidity sensor is arranged in the external environment to acquire the external environment humidity Hw.

[0095] Specifically, if Hs < Hw, the exhaust port 12 is communicated with the first exhaust pipeline 52; if Hs ≥ Hw, the exhaust port 12 is communicated with the second exhaust pipeline 53.

[0096] Through such a setting, when the actual humidity Hs in the battery compartment 1 is less than the external environment humidity, it indicates that the current humidity in the battery compartment 1 is high but still lower than the external environment humidity, at this time, the exhaust port 12 is communicated with the first exhaust pipeline 52, the air in the battery compartment 1 can be exhausted into the air dehumidification chamber 2, and then the dehumidification device 3 dehumidifies the air exhausted into the air dehumidification chamber 2, which helps to save energy; when the actual humidity H1 in the battery compartment 1 is greater than or equal to the external environment humidity, it indicates that the humidity in the battery compartment 1 is too high, at this time, the exhaust port 12 is communicated with the second exhaust pipeline 53, which can avoid exhausting the air with higher humidity in the battery compartment 1 into the air dehumidification chamber 2, and the air in the external environment can be directly delivered into the air dehumidification chamber 2, thereby the dehumidification energy consumption of the dehumidification device 3 can be reduced, which helps to save energy.

[0097] Specifically, when the dry air is delivered into the battery compartment 1, the fan is started to deliver the dry air in the air dehumidification chamber 2 or the air storage chamber 4 into the battery compartment 1.

[0098] It should be noted that after the fan is started, the person skilled in the art can close the fan when the running time of the fan reaches the preset time, or can obtain the current humidity in the battery compartment 1 in real time, and make the fan close when the current humidity is lower than the preset humidity, and the like, and such adjustment and change of the running time of the fan do not deviate from the principles and scope of the present application, and should be included in the protection scope of the present application.

[0099] Preferably, after the fan is started, the current humidity Hd in the battery compartment 1 is obtained in real time; the current humidity Hd is compared with the preset humidity H0; and according to the comparison result, the air in the air dehumidification chamber 2 is selectively stopped from being delivered into the battery compartment 1.

[0100] Through such a setting, the air in the air dehumidification chamber 2 can be timely stopped from being delivered into the battery compartment 1 when the current humidity is lower than the preset humidity, avoiding the problems of energy waste and further increase of the humidity in the battery compartment 1 caused by the air in the air dehumidification chamber 2 being delivered into the battery compartment 1 when the humidity in the battery compartment 1 is low.

[0101] Specifically, if Hd < H0, the air in the air dehumidification chamber 2 is stopped from being delivered into the battery compartment 1.

[0102] When Hd < H0, it indicates that the current humidity in the battery compartment 1 has been reduced to within the preset humidity range, and at this time, the air in the air dehumidification chamber 2 is timely stopped from being delivered into the battery compartment 1, avoiding the problems of energy waste and further increase of the humidity in the battery compartment 1 caused by the air in the air dehumidification chamber 2 being delivered into the battery compartment 1 when the humidity in the battery compartment 1 is low.

[0103] If Hd ≥ H0, the air in the air dehumidification chamber 2 is not stopped from being delivered into the battery compartment 1.

[0104] In the case of Hd ≥ H0, it indicates that the air humidity in the battery compartment 1 is still high, and the air in the air dehumidification chamber 2 after dehumidification still needs to be delivered into the battery compartment 1 in order to reduce the air humidity in the battery compartment 1.

[0105] Preferably, after the air with high humidity is delivered into the air dehumidification chamber 2, the external environment temperature Ti corresponding to the ith moment within a preset time is obtained; the lowest temperature Tn in the external environment temperature Ti within the preset time is determined; and the dehumidification device 3 dehumidifies the air in the air dehumidification chamber 2 at the nth moment; wherein i > 0 and i is a positive integer, 0 < n < i and n is a positive integer.

[0106] Through the arrangement, the dehumidification device 3 dehumidifies the air in the air dehumidification chamber 2 when the external environment temperature is low, energy can be saved more, and the use experience of the user is further improved.

[0107] It should be noted that the preset time is not limited in the present application, for example, the preset time can be set to 4h, 8h, 12h, 16h, 20h, 24h or a range formed by any two of these values.

[0108] Exemplarily, the preset time is 24h.

[0109] It should be noted that in actual application, it is not limited to dehumidifying the air in the air dehumidification chamber 2 by the dehumidification device 3 when the external environment temperature is low, for example, the dehumidification device 3 can dehumidify the air in the air dehumidification chamber 2 immediately after stopping the delivery of dry air into the battery compartment 1, or the dehumidification device 3 can dehumidify the air in the air dehumidification chamber 2 while delivering dry air into the battery compartment 1, etc., the adjustment and change of the specific time of dehumidifying the air in the air dehumidification chamber 2 by the dehumidification device 3 does not deviate from the principles and scope of the present application, and should be included in the protection scope of the present application.

[0110] Of course, preferably, the dehumidification device 3 dehumidifies the air in the air dehumidification chamber 2 when the external environment temperature is low.

Those skilled in the art can make equivalent changes or replacements to related technical features without deviating from the principles of the present application, and the technical scheme after the changes or replacements will fall within the protection scope of the present application.
