Shown in the accompanying drawings are exemplary embodiments of the present application. However, the present application can be implemented in many different forms and should not be construed as being limited to the exemplary embodiments set forth herein. These exemplary embodiments are provided to make the present application thorough and complete, and to fully convey the scope of the present application to those skilled in the art. Similar reference numerals represent identical or similar components.

[0048] Reference Figure 1 The present application proposes a humidity regulating device 100, which includes a humidity detecting device 110, a temperature detecting device 200, a condensing device 120, a fan 130 and a main control module 140. The humidity detecting device 110 is used to detect the air humidity in the target space. The temperature detecting device 200 is used to detect the air temperature in the target space. The condensing device 120 is used to adjust the air humidity in the target space. The fan 130 is used to form a circulating air duct in the target space. The main control module 140 is electrically connected to the humidity detection device 110, the condensing device 120 and the fan 130. The main control module 140 is used to obtain the air humidity detected by the humidity detection device 110 and the air temperature detected by the temperature detection device 200; the main control module 140 is also used to obtain the output power of the energy storage device and generate a power-temperature parameter; and the main control module 140 is also used to control the condensing device 120 to work when the air humidity is greater than or equal to the humidity threshold, and / or the power-temperature parameter is greater than or equal to the parameter threshold; and, when the air humidity is less than the humidity threshold and the power-temperature parameter is less than the parameter threshold, the condensing device 120 is controlled to stop working and the fan 130 is controlled to work according to a preset cycle; the preset cycle includes a working cycle and an interval cycle, and the main control module 140 is used to control the fan 130 to work during the working cycle and to control the fan 130 to stop working during the interval cycle.

[0049] In this embodiment, the humidity detection device 110 can be implemented by a humidity sensor, the temperature detection device 200 can be implemented by a temperature sensor, and the condensing device 120 can be implemented by a condenser. The main control module 140 may include a control unit and a storage unit. Among them, a chip with a control function such as a microprocessor, FPGA, etc. can be selected to implement. The storage unit is used to store the humidity data detected by the humidity detection device 110, and a memory can be selected to implement. Alternatively, the control unit and the storage unit can be integrated into the same chip.

[0050] The humidity regulating device 100 of this embodiment can be applied to electronic devices such as energy storage devices, chassis, and power supply cabinets. Taking energy storage devices as an example, the humidity in different areas inside the energy storage device may be uneven. The main control module 140 can control the fan 130 to start rotating, so that the air inside the energy storage device circulates in the air duct, passes through the humidity detection device 110 and the condensation device 120, so that the humidity detection device 110 can more accurately collect the air humidity parameters inside the energy storage device, and improve the condensation efficiency of the condensation device 120. The main control module 140 compares the humidity parameter detected by the humidity detection device 110 with the humidity threshold. When the air humidity is greater than or equal to the humidity threshold, it means that the humidity inside the energy storage device is large, which may affect the normal operation of the electronic device. At this time, the main control module 140 controls the condensation device 120 and the fan 130 to work, and converts the water vapor in the energy storage device into liquid for discharge to reduce the air humidity in the energy storage device. In addition, the energy storage device may have low power but high temperature during operation, or high ambient temperature but low actual power due to aging or failure. This will also cause the condensed water inside the energy storage device to evaporate into water vapor again, increasing the humidity. Therefore, the main control module 140 can also adjust the humidity based on the power-temperature parameters of the energy storage device. When the power-temperature parameter is greater than or equal to the parameter threshold, it means that the output power and / or temperature of the energy storage device is high, and the main control module 140 controls the condensing device 120 and the fan 130 to work. The energy storage device generates heat during operation. When the air temperature is greater than or equal to the temperature threshold, it means that the temperature inside the energy storage device is high, and the main control module 140 controls the fan 130 and the condensing device 120 to work to dissipate heat inside the energy storage device.

[0051] When the air humidity is less than the humidity threshold and the power-temperature parameter is less than the parameter threshold, it means that the humidity inside the energy storage device is low, and the power and temperature of the energy storage device are also low, and the energy storage device may be in a low power consumption or shutdown state. In order to reduce power consumption, the main control module 140 can control the fan 130 to work intermittently at this time to intermittently collect the humidity inside the energy storage device. For example, the fan 130 can be controlled to work according to a preset cycle. The preset cycle includes a working cycle and an interval cycle. The main control module 140 is used to control the fan 130 to work during the working cycle and control the fan 130 to stop working during the interval cycle. By controlling the fan 130 to work at intervals through the main control module 140, it does not affect the detection of air humidity and can also reduce the power consumption of the humidity regulating device 100.

[0052] In one embodiment, the main control module 140 is used to control the fan 130 and the condensing device 120 to operate when the air humidity is greater than or equal to the humidity threshold, and / or the power-temperature coordinate value is greater than or equal to the power-temperature curve; the main control module 140 is used to control the condensing device 120 to stop operating and control the fan 130 to operate according to a preset cycle when the air humidity is less than the humidity threshold and the power-temperature coordinate value is less than the power-temperature curve.

[0053] In this embodiment, the temperature of the normally operating energy storage device at different output powers can be collected through multiple experiments to generate a power-temperature curve as a reference. Figure 2 As shown, when the power-temperature coordinate value is greater than the power-temperature curve (such as P1) or equal to the power-temperature curve (such as P2), it means that the temperature of the energy storage device is high at the current output power, which may cause the internal humidity of the energy storage device to increase. At this time, the main control module 140 controls the fan and the condensing device to work. When the main air humidity is less than the humidity threshold, and the power-temperature coordinate value is less than the power-temperature curve (such as P3), it means that the internal temperature of the energy storage device is low at the current output power, and the impact on humidity is small. At this time, the main control module 140 can control the fan to work at intervals.

[0054] In addition, the parameter threshold value may also include a power-temperature correspondence table, which includes temperature threshold values ​​in the energy storage device at different powers. If the detected temperature is greater than or equal to the temperature threshold value at the current output power of the energy storage device, and the air humidity is less than the humidity threshold value, the main control module 140 controls the fan and the condensing device to work. If the detected temperature is less than the temperature threshold value, the main control module 140 controls the fan to work at intervals.

[0055] Further, when the main control module 140 controls the fan 130 to start rotating, the initial rotation duration of the fan 130 can be set to the first preset duration. Within the first preset duration, if it is detected that the air humidity is greater than or equal to the humidity threshold, the condensing device 120 is controlled to start working; if it is detected that the air humidity is always less than the humidity threshold within the first preset duration, the fan 130 is controlled to work according to the preset cycle. Among them, the interval period in the preset cycle can start after the end of the working cycle. That is, after the first preset duration ends, the fan 130 is controlled to continue to rotate for one working cycle, and then the fan 130 is controlled to stop working for an interval period, and then the fan 130 is controlled to rotate for one working cycle... In this way, the fan 130 is controlled to work at intervals, and the air humidity in the energy storage device is continuously detected during the working cycle. If it is detected that the air humidity in the energy storage device is greater than or equal to the humidity threshold during the working cycle, the condensing device 120 is controlled to work until the air humidity is less than the humidity threshold, and then the fan 130 is controlled to work according to the preset cycle. In this way, the main control module 140 controls the fan 130 to continue to rotate for one working cycle when the air humidity is less than the humidity threshold, so as to ensure that the air humidity is stably less than the humidity threshold, and then controls the fan 130 to stop working for an interval cycle, thereby reducing the power consumption of the humidity regulating device 100 and improving the stability of the humidity regulating device 100. Among them, the first preset time length can be set according to the actual application scenario, and the working cycle and the interval cycle can be set to be the same or different.

[0056] The present application forms a circulating air duct in the target space through the fan 130, so that the water vapor in the target space is evenly distributed, and the accuracy of the humidity detection device 110 in detecting the air humidity in the target space is improved. When the air humidity is greater than or equal to the air threshold, and / or the power-temperature parameter is greater than or equal to the parameter threshold, the main control module 140 controls the condensing device 120 to work, so as to reduce the air humidity in the target space, adjust the air humidity in the target space, and avoid the electronic devices in the target space from not being able to work normally due to high humidity. And when the air humidity is less than the humidity threshold, and the power-temperature parameter is less than the parameter threshold, the condensing device 120 is controlled to stop working, and the fan 130 is controlled to work at a preset periodic interval to reduce the power consumption of the humidity regulating device 100.

[0057] Reference Figures 3-5The present application also proposes a humidity regulating device 100, which includes a mounting base 150, a fan 130, a humidity detection device 110, a condensation device 120 and a main control module 140. A mounting hole is provided at the bottom of the mounting base 150. The fan 130 is fixedly mounted on the first side wall of the mounting base 150. The humidity detection device 110 is arranged on the air inlet side of the fan 130 close to the fan 130. The condensation device 120 is fixedly mounted on the mounting base 150 close to the air outlet side of the fan 130. The main control module 140 is fixedly mounted on the first side wall or the second side wall of the mounting base 150; the first side wall and the second side wall are opposite to each other.

[0058] In this embodiment, the mounting base 150 can be set to various shapes such as L-shaped, a hollow shell, a plate-shaped, etc. according to actual needs, and no limitation is made here. For example, the mounting base 150 can be set to an "L" shape, and the mounting hole is set on the "_"-shaped plate at the bottom of the "L" shape, and the fan 130, the humidity detection device 110, the condensing device 120 and the main control module 140 are set on the "|"-shaped plate of the "L" shape. The side of the "|"-shaped plate close to the "_"-shaped plate is the first side wall of the mounting base 150. In this way, the fan 130, the humidity detection device 110, the condensing device 120 and the main control module 140 can all be accommodated in the internal space formed by the "L"-shaped mounting base 150, and the side walls on both sides of the "L"-shaped mounting base 150 have a certain protective effect on the internal fan 130, the humidity detection device 110, the condensing device 120 and the main control module 140.

[0059] In one embodiment, the air outlet of the fan 130 can be arranged near the first side wall, and the condensing device 120 can be arranged between the first side wall and the fan 130, or the position of the first side wall corresponding to the air outlet of the fan 130 can be hollowed out to fix the condensing device 120 in the first side wall to reduce the occupied space of the humidity regulating device 100. The humidity detection device 110 can be arranged on the second side wall of the rear mounting base 150 on the fan 130 near the air inlet of the fan 130. The control main control module 140 can be arranged near the fan 130 at the upper, lower, left and right sides of the fan 130 to reduce the wiring length between the main control module 140 and the fan 130 and the condensing device 120.

[0060] In one embodiment, the humidity regulating device 100 further includes a condensed water collecting device 160 , which is disposed below the condensing device 120 and is used to collect the condensed water processed by the condensing device 120 .

[0061] In this embodiment, the main control module 140 can be arranged above the fan 130 away from the condensate collection device 160 to prevent the outflow of condensate from affecting the normal operation of the main control module 140. The condensate collection device 160 can be set to a cube, a triangle, a cylinder, etc. according to actual needs, and is not limited here. For example, the condensate collection device 160 can be set to a cone with a wide top and a narrow bottom. The wide mouth at the top is convenient for collecting condensate, the cone is convenient for guiding the condensate to be discharged downward, and the narrow mouth at the bottom is convenient for the condensate to be discharged from a fixed position.

[0062] In one embodiment, a one-way water guide film 170 is disposed at the water outlet of the condensate collection device 160 ; the water guide direction of the one-way water guide film 170 is from inside the condensate collection device 160 to outside the condensate collection device 160 .

[0063] In this embodiment, the one-way water-conducting membrane 170 can be realized by using a one-way liquid-conducting membrane or a semi-permeable membrane. By setting the one-way water-conducting membrane 170, the condensed water is controlled to flow out from the inside of the condensed water collecting device 160, and water is prevented from flowing from the outside into the condensed water collecting device 160, thereby avoiding the condensed water from flowing back and improving the reliability of the humidity control device 100.

[0064] In one embodiment, a through hole 180 is provided at a position of the mounting base 150 corresponding to the water outlet of the condensed water collecting device 160 .

[0065] In this embodiment, the size of the through hole 180 can be set according to the size of the water outlet of the condensate collecting device 160. The water outlet of the condensate collecting device 160 can be snapped into the through hole 180, so that the condensate collecting device 160 is fixed on the mounting base 150.

[0066] In one embodiment, the humidity adjustment device 100 further includes a communication interface 190 , and the communication interface 190 is disposed on the mounting base 150 .

[0067] In this embodiment, the communication interface 190 is electrically connected to the main control module 140. The communication interface 190 can be used to access the power supply voltage and can also communicate with external devices. The communication interface 190 can be installed on the mounting base 150 close to the main control module 140 to reduce the wiring length between the main control module 140.

[0068] The present application also proposes an energy storage device, which includes the humidity regulating device 100 mentioned above.
