Description

Technical Field

[0001] This invention relates to the field of water vapor removal technology for household energy storage devices, and specifically discloses a water vapor removal device and its control method for household energy storage devices. Background Technology

[0002] With the energy transition and the rapid development of renewable energy, the demand for energy storage devices is increasing. A crucial issue that needs to be addressed is preventing moisture from entering the equipment, as moisture can lead to performance degradation, shortened lifespan, and safety hazards. Therefore, the application of water vapor removal technology is essential for the maintenance and lifespan extension of energy storage devices. Typically, energy storage devices use sealing rings to prevent water vapor ingress. However, with prolonged use, these sealing rings can age, deteriorate, and detach, allowing water vapor to enter the energy storage device.

[0003] Water vapor in energy storage devices primarily originates from moisture inside the device and in the external environment. Internal moisture may seep in through component materials, seals, cable connectors, etc.; external moisture may come from atmospheric humidity, rain, fog, dew, etc. Failure to promptly remove water vapor adhering to batteries or circuit boards can easily lead to a decline in the performance of energy storage devices, primarily in three aspects: Electrical performance: Water vapor degrades the electrical performance of energy storage devices, such as reduced capacity, increased internal resistance, and decreased charge / discharge efficiency; Mechanical performance: Water vapor degrades the mechanical performance of energy storage devices, such as reduced material strength, decreased sealing performance, and corrosion of structural components; Safety performance: Water vapor increases safety hazards in energy storage devices, such as short circuits, leakage, and fire.

[0004] Different defogging technologies applied to energy storage devices can effectively remove moisture, improving device performance and lifespan. Currently, the main methods for defogging energy storage devices include: 1. Heating and drying technology can remove moisture from inside the device, but it consumes a significant amount of additional energy; 2. Moisture-absorbing material technology can absorb and store moisture inside the device, but defogging is not thorough; 3. Compressed air technology can use compressed air to blow out moisture from inside the device, but compressed air also contains moisture, resulting in incomplete defogging; 4. Photoelectric defogging technology can use the photoelectric effect to decompose moisture inside the device into hydrogen and oxygen, but it also consumes a significant amount of additional energy. Summary of the Invention

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a water vapor removal device and its control method for household energy storage devices, thereby solving the problems of excessive additional energy consumption and incomplete defogging in existing defogging methods.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] A water vapor removal device for a household energy storage device includes a housing with multiple sets of battery cells inside, each with a heat sink. A fan is mounted on the inner wall of the front end of the housing in conjunction with the heat sink. A TEC (Thermostatic Control Unit) cooling fin is mounted on the inner wall of the rear end of the housing. A condenser plate is attached to the inner side of the TEC cooling fin. The heat sink facilitates heat dissipation from the battery cells. The fan, working in conjunction with the heat sink, blows the heat dissipated from the battery cells towards the condenser plate, which is then cooled by the TEC cooling fin. Upon contact with the condenser plate, the heated air condenses due to the significant temperature difference, effectively removing moisture or mist from the air inside the household energy storage device. Furthermore, the addition of the fan and TEC cooling fin results in less additional energy consumption compared to existing technologies.

[0008] Preferably, a water guide groove is provided below the condenser plate; the water guide groove is located on the bottom surface of the casing. This allows water dripping from the condenser plate to be collected, facilitating cleaning.

[0009] Preferably, absorbent material is provided in the water guide channel to further ensure the absorption and collection of water.

[0010] Preferably, one end of the condenser plate is fixedly mounted on the side wall of the housing to ensure the stability of the condenser plate and facilitate disassembly and assembly.

[0011] Preferably, detachable baffles are provided on both the front and rear sides of the housing to facilitate cleaning of moisture from the absorbent material in the water guide channel.

[0012] Preferably, a thermometer and a hygrometer are installed inside the casing; a thermometer is installed on the condenser plate. This allows for real-time monitoring and data acquisition of the temperature and humidity inside the household energy storage device, as well as the temperature on the condenser plate.

[0013] Preferably, a controller is installed inside the housing; the controller is electrically connected to a thermometer and a hygrometer inside the housing; the controller is electrically connected to a thermometer on the condenser plate; the fan and the TEC cooling plate are both electrically connected to the controller.

[0014] A control method for a water vapor removal device in a household energy storage equipment includes:

[0015] S1 detects the internal temperature T1, humidity H1, and condenser plate temperature T2 of the home energy storage device;

[0016] S2: Determine if the humidity H1 meets the requirements for removing water vapor. If yes, proceed to S3; otherwise, return to S1.

[0017] S3, determine whether the difference between the internal temperature T1 and the temperature T2 of the condenser plate meets the condensation requirement; if yes, proceed to S5; if no, proceed to S4.

[0018] S4 activates the TEC cooling chip;

[0019] S5, turn on the fan.

[0020] Preferably, step S4 is followed by step S3.

[0021] Preferably, step S5 is followed by the following step:

[0022] S6, determine whether the humidity H1 continues to increase; if yes, proceed to S7, then return to S6; if no, proceed to S8.

[0023] S7 increases fan speed;

[0024] S8, retrieves fan speed, internal temperature T1, and humidity H1;

[0025] S9, determine if the humidity H1 has decreased below the required level; if yes, end; if no, return to S3.

[0026] The beneficial effects of this invention are as follows:

[0027] When the internal humidity of the home energy storage device reaches the preset value, and the condenser plate is cooled by controlling the TEC cooling chip to ensure that the temperature difference between the internal temperature and the condenser plate reaches the preset value, the fan is turned on to remove moisture from the air using the condenser plate. During this process, humidity changes are monitored in real time. If the humidity continues to increase, the fan speed is increased. If it no longer increases, the fan speed is maintained, and the dehumidification process ends when the humidity drops below the preset value.

[0028] This invention utilizes the waste heat generated by the battery cells for the water vapor removal process, minimizing energy consumption and enabling efficient energy utilization while reducing water vapor removal costs. Through a continuous cycle, this invention continuously removes moisture from the interior of home energy storage devices, ensuring stable operation and preventing equipment malfunctions and performance degradation caused by moisture accumulation. The method and apparatus of this invention are simple in structure, easy to implement and maintain, and can be applied to various types of energy storage devices, showing broad application prospects. The water vapor removal device and control method for home energy storage devices provided by this invention have advantages such as high efficiency, energy saving, reliability, and feasibility, and can be further optimized and improved through control, safety considerations, and system integration. This can improve the performance, reliability, lifespan, and safety of home energy storage devices, while reducing environmental impact and lowering operating costs. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0039] like Figure 1-2As shown, a water vapor removal device for a household energy storage device includes a housing 1, within which multiple sets of battery cells are installed, with heat sinks 2 surrounding each cell. A fan 3 is mounted on the inner wall of the front end of the housing 1 in conjunction with the heat sinks 2. A TEC cooling plate 4 is mounted on the inner wall of the rear end of the housing 1. A condenser plate 5 is attached to the inner side of the TEC cooling plate 4. The heat sinks 2 facilitate the dissipation of heat from the battery cells. The fan 3, in conjunction with the heat sinks 2, blows the heat dissipated from the battery cells onto the condenser plate 5, which is cooled by the TEC cooling plate 4. Upon contact with the condenser plate 5, the heated air condenses and condenses on it due to the significant temperature difference, effectively removing moisture or mist from the air inside the household energy storage device. Furthermore, the addition of the fan 3 and the TEC cooling plate 4 results in less additional energy consumption compared to existing technologies. A water channel 6 is located below the condenser plate 5; the water channel 6 is situated on the bottom surface of the housing 1 and collects dripping water from the condenser plate 5 for easy cleaning. Absorbent material is placed inside the water channel 6 to further ensure water absorption and collection. A thermometer and a hygrometer are installed inside the housing 1; a thermometer is also installed on the condenser plate 5. A controller is installed inside the housing 1; the controller is electrically connected to the thermometer and hygrometer inside the housing 1; the controller is also electrically connected to the thermometer on the condenser plate 5; the fan 3 and the TEC cooling element 4 are both electrically connected to the controller. This allows for real-time monitoring and data acquisition of the temperature and humidity inside the household energy storage device, as well as the temperature on the condenser plate 5.

[0040] In the above configuration, one end of the condenser plate 5 is fixed to the side wall of the housing 1 to ensure the stability of the condenser plate 5 and facilitate disassembly and assembly. Both ends of the TEC cooling plate 4 are set on the inner wall of the housing to ensure stable installation. Removable baffles are provided on both the front and rear sides of the housing 1, and the baffles are fixed with bolts for easy sealing. This facilitates the cleaning of moisture from the water-absorbing material in the water guide channel 6.

[0041] like Figure 3 As shown, a control method for a water vapor removal device in a household energy storage device is described.

[0042] S1 detects the internal temperature T1, humidity H1, and condenser plate temperature T2 of the home energy storage device;

[0043] S2, determine whether the humidity H1 meets the requirements for removing water vapor, that is, determine whether the humidity H1 is greater than the preset value. If yes, proceed to S3; otherwise, return to S1.

[0044] S3, determine whether the difference between the internal temperature T1 and the temperature T2 of the condenser plate meets the condensation requirement, that is, determine whether the difference between the internal temperature T1 and the temperature T2 of the condenser plate is greater than the preset value; if yes, proceed to S5; if no, proceed to S4.

[0045] S4 activates the TEC cooling chip;

[0046] S5, turn on the fan.

[0047] Preferably, step S4 is followed by step S3.

[0048] Preferably, step S5 is followed by the following step:

[0049] S6, determine whether the humidity H1 continues to increase; if yes, proceed to S7, then return to S6; if no, proceed to S8.

[0050] S7 increases fan speed;

[0051] S8, retrieves fan speed, internal temperature T1, and humidity H1;

[0052] S9, determine if the humidity H1 has decreased below the required level; if yes, end; if no, return to S3.

[0053] When the internal humidity H1 of the home energy storage device reaches the preset value, and the condenser plate 5 is cooled by controlling the TEC cooling chip 4 to ensure that the difference between the internal temperature T1 and the temperature T2 of the condenser plate 5 reaches the preset value, the fan is turned on to remove moisture from the air using the condenser plate. During this process, the humidity change is monitored in real time. If the humidity continues to increase, the fan speed is increased. If it no longer increases, the fan speed is maintained, and the dehumidification ends when the humidity drops below the preset value.

[0054] This invention utilizes the waste heat generated by the battery cells for the water vapor removal process, minimizing energy consumption and enabling efficient energy utilization while reducing water vapor removal costs. Through a continuous cycle, this invention continuously removes moisture from the interior of home energy storage devices, ensuring stable operation and preventing equipment malfunctions and performance degradation caused by moisture accumulation. The method and apparatus of this invention are simple in structure, easy to implement and maintain, and can be applied to various types of energy storage devices, showing broad application prospects. The water vapor removal device and control method for home energy storage devices provided by this invention have advantages such as high efficiency, energy saving, reliability, and feasibility, and can be further optimized and improved through control, safety considerations, and system integration. This can improve the performance, reliability, lifespan, and safety of home energy storage devices, while reducing environmental impact and lowering operating costs.

[0055] like Figure 4-6 As shown, as the usage time of this invention increases, a water film continuously accumulates on the condenser plate in the home energy storage device. Once the water film reaches a certain thickness, it flows into the water guide channel and is absorbed by the water-absorbing material, ensuring the dryness inside the home energy storage device and extending the service life of the device.
