During transportation and storage, it is usually stored in an energy storage box (including energy storage containers and energy storage outdoor cabinet products). Since the protection level of the battery pack is higher than that of the energy storage box, and condensation may cause electrical accidents and equipment damage, a dehumidifier needs to be additionally installed in the energy storage box.

[0003] In the prior art, determining whether to turn on the dehumidifier mainly depends on the temperature of the liquid cooling plate in the energy storage box, or is determined by the current dehumidification amount and the required dehumidification amount.

[0028] To enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the scope of protection of the present invention.

[0029] Figure 1 The figure is a flowchart of a dehumidification control method for an energy storage box provided by an embodiment of the present invention. This embodiment is applicable to the situation of dehumidification control of the energy storage box. This method can be executed by a dehumidification control device for the energy storage box. The dehumidification control device for the energy storage box can be implemented in the form of hardware and / or software, and the dehumidification control device for the energy storage box can be configured in an electronic device. As Figure 1 shown, the dehumidification control method for the energy storage box includes:

[0030] S101. Establish a system model of the energy storage box.

[0031] The system model is a single-cluster or multi-cluster unit model. Specifically, ANSYS simulation software or FLUENT simulation software is used to establish the system model of the energy storage box. During the simulation process, the division of fluid grids is crucial. By reasonably dividing the grids, the energy transport phenomenon in the fluid can be more accurately simulated, thereby improving the accuracy of the simulation. At the same time, the fineness of the grids will also affect the calculation efficiency of the simulation and the accuracy of the results. Therefore, when dividing the fluid grids, it is necessary to comprehensively consider the simulation requirements and computing resources and select an appropriate grid division strategy.

[0032] S102. Perform simulation on the installation position of the dehumidifier in the energy storage box according to the preset air flow requirement parameters and the dehumidification parameters of the dehumidifier to determine the target installation position of the dehumidifier.

[0033] Generally, the dehumidifier has forward air intake, downward air intake, and upward air outlet (exhaust). The energy storage cabinet is a product with a very high IP rating (IP66 or IP55). To ensure the dehumidification effect, a stable and uniform air flow field is required. According to the principle of the dehumidifier, the humid air in the air passes through the cold end of the thermoelectric cooler TEC, and the moisture in the air condenses on the surface of the cold end evaporator and is collected, thereby reducing the humidity of the air and realizing the dehumidification function of the required space. To ensure the overall dehumidification effect, especially to avoid condensation on all key components, the entire air flow field must be balanced. Therefore, in the air flow simulation, the following aspects are mainly concerned:

[0034] (1) Air flow velocity determination: Judge whether the air flow velocity distribution in each area is reasonable to avoid abnormal high-speed or low-speed areas;

[0035] (2) Determination of air flow stability: Air flow stability refers to the volatility of the air flow field over time. When evaluating air flow stability, it is necessary to pay attention to the time fluctuation amplitude of the air flow velocity, the overall stability of the air flow field, and whether there are local unstable regions.

[0036] (3) Determination of air flow distribution: Evaluate whether the overall distribution of the air flow field is reasonable to ensure that the air flow distribution in each region is uniform and there are no obvious differences.

[0037] In this embodiment, the air flow requirement parameters include stability requirement parameters and uniformity requirement parameters.

[0038] In an alternative embodiment, the stability requirement parameter can be that the time fluctuation amplitude of the air flow velocity is less than a first preset amplitude, and the uniformity requirement parameter can be that the difference in air flow velocity within each preset region is less than a second preset amplitude, and / or the difference in the volume flow rate of the air flow field within each preset region is less than a third preset amplitude. The preset region can be the region of interest in the energy storage box or each region divided by the flow space of the air flow inside the entire energy storage box, and can be specifically set according to actual needs. Under the limitation of the air flow requirement parameters, the installation position of the dehumidifier in the energy storage box is simulated, and the simulated installation position can make the air flow inside the energy storage box meet the air flow requirement parameters when the dehumidifier works, that is, it has stability and uniformity.

[0039] In an alternative embodiment, the target installation position obtained after simulation is the middle position of the door panel of the energy storage box.

[0040] S103. Install the dehumidifier at the target installation position and input the parameters of the enthalpy-humidity diagram under standard atmospheric pressure into the dehumidification controller.

[0041] The enthalpy-humidity diagram uses specific enthalpy as the vertical coordinate and moisture content as the horizontal coordinate to represent the relationship between the various parameters of moist air under a certain atmospheric pressure. Its function is to determine the state parameters of the time controller and represent the state change process of moist air. Simply put, the most basic application of the enthalpy-humidity diagram is to find parameters. The dew point temperature is an important state parameter of moist air. The dew point temperature refers to the temperature at which the air is cooled to saturation while keeping the water vapor content in the air unchanged and the pressure constant, and is expressed in °C or °F. In fact, it is also the temperature at which water vapor and water reach an equilibrium state. When the humidity and temperature of the air are known, the corresponding dew point temperature can be found in the enthalpy-humidity diagram.

[0042] It should be noted that the environment where the energy storage box in the present invention is located is under standard atmospheric pressure.

[0043] S104. Install temperature and humidity sensors in the preset sensor area and the target installation position and detect the temperature and humidity.

[0044] The target installation position is the placement position of the dehumidifier. The surrounding of this position is air. Therefore, the temperature and humidity sensors at this position can be used to detect the air temperature and air humidity, and then the current dew point temperature can be calculated. The temperature and humidity sensors located in the preset sensor area are used to detect the temperature and humidity of the corresponding area.

[0045] Among them, the sensor area includes a preset easy-to-condense area and a key component area. Optionally, the easy-to-condense area includes areas where the surface temperature is lower than the average temperature inside the energy storage box system. There is a charging and discharging process in the battery cells of the battery pack, and charging and discharging generate heat, which easily heats the air around the battery pack. Some component surfaces have a lower temperature, such as the liquid-cooled bottom plate (for circulating the coolant of the liquid-cooled unit) and the liquid-cooled pipe channel (for transporting the cooling liquid), resulting in a certain temperature difference between the surface of the component with a lower temperature and the air, which easily forms condensation. The easy-to-condense area also includes the component area with hygroscopic materials. For example, the upper cover of the battery pack is made of SPCC steel plate and is prone to condensation under specific conditions. The key component area is the area where the core communication and power components that need to prevent condensation are located. For example, the communication harness and circuit board area, to prevent condensation from causing damage to communication, signals, and power. In summary, temperature and humidity sensors need to be set in the easy-to-condense area and the key component area.

[0046] In an optional embodiment, the easy-to-condense area includes the liquid-cooled bottom plate and the upper cover of the liquid-cooled battery pack, and / or the key component area includes the internal frame points of the cabinet.

[0047] S105. Control the operation of the dehumidifier according to the detected temperature, humidity, and the parameters of the psychrometric chart.

[0048] Specifically, the air temperature and air humidity can be detected by the temperature and humidity sensors located at the target installation position. Then, the corresponding dew point temperature can be obtained according to the psychrometric chart. When the temperature in the sensor area is lower than the dew point temperature, the dehumidifier can be controlled to start working.

[0049] The dehumidification control method for an energy storage box provided by an embodiment of the present invention establishes a system model of the energy storage box, and performs simulation on the installation position of a dehumidifier in the energy storage box according to preset air flow requirement parameters and dehumidification parameters of the dehumidifier to determine the target installation position of the dehumidifier. The air flow requirement parameters include stability requirement parameters and uniformity requirement parameters. The dehumidifier is installed at the target installation position, and the parameters of the enthalpy-humidity diagram under standard atmospheric pressure are input into the dehumidification controller. Temperature and humidity sensors are installed in the preset sensor area and the target installation position to detect temperature and humidity. The sensor area includes a preset condensation-prone area and a key component area. The operation of the dehumidifier is controlled according to the detected temperature, humidity and the parameters of the enthalpy-humidity diagram. By setting the installation position of the dehumidifier through simulation based on the air flow requirement parameters, when the dehumidifier operates, the internal air flow of the energy storage box can reach the preset stability and uniformity effects, that is, it can ensure the overall dehumidification effect of the dehumidifier in the energy storage box and avoid dehumidification "dead corners". In addition, by arranging sensors in the condensation-prone area and the key component area, the temperature and humidity of these key parts can be accurately and timely detected and dehumidified, avoiding the occurrence of water vapor in the condensation-prone area and the key component area.

[0050] In an optional embodiment, performing simulation on the installation position of a dehumidifier in the energy storage box according to preset air flow requirement parameters and dehumidification parameters of the dehumidifier to determine the target installation position of the dehumidifier includes: setting boundary conditions and initial conditions of the system model, where the initial conditions include the initial velocity and initial temperature of the gas inside the system model; taking the preset air flow requirement parameters as the target, and performing numerical simulation and solution according to the dehumidification parameters, boundary conditions and initial conditions of the dehumidifier to determine the target installation position of the dehumidifier.

[0051] The initial conditions are the air flow conditions inside the energy storage box before the dehumidifier is turned on.

[0052] In an optional embodiment, taking the preset air flow requirement parameters as the target, performing numerical simulation and solution according to the dehumidification parameters, boundary conditions and initial conditions of the dehumidifier to determine the target installation position of the dehumidifier includes: determining the initial position of the dehumidifier; performing simulation according to the current position of the dehumidifier, the dehumidification parameters, boundary conditions and initial conditions of the dehumidifier to obtain air flow simulation parameters; determining whether the air flow simulation parameters meet the preset air flow requirement parameters; if so, determining the current position of the dehumidifier as the target installation position; if not, updating the position of the dehumidifier with a preset moving step length, and returning to the step of performing simulation according to the current position of the dehumidifier, the dehumidification parameters, boundary conditions and initial conditions of the dehumidifier to obtain air flow simulation parameters.

[0053] During the above simulation process, the current position of the dehumidifier is continuously updated, and it is determined whether the current air flow simulation parameters meet the air flow requirement parameters. When the air flow requirement parameters are met, the current position of the dehumidifier can be determined as the target installation position.

[0054] In an optional embodiment, the dehumidifier is controlled to operate according to the detected temperature, humidity, and parameters of the psychrometric chart, including: obtaining the air temperature and air humidity through the temperature and humidity sensors located at the target installation position; determining the corresponding dew point temperature from the parameters of the psychrometric chart according to the air temperature and air humidity; obtaining the first lowest temperature point among the temperatures detected by the temperature and humidity sensors in the sensor area; controlling the dehumidifier to operate according to the first lowest temperature point, the dew point temperature, and the air humidity.

[0055] The area where the first lowest temperature point is located is the area where condensation is most likely to occur. Therefore, the dehumidifier can be controlled to operate according to the first lowest temperature point, the dew point temperature, and the air humidity. Specifically, controlling the dehumidifier to operate according to the lowest temperature point, the dew point temperature, and the air humidity includes: when the first lowest temperature point is less than or equal to the dew point temperature, or when the air humidity is greater than a preset humidity threshold, controlling the dehumidifier to start.

[0056] On the one hand, the dew point temperature can be used to accurately detect the area where condensation is likely to occur. When the surface temperature of an object is lower than the dew point temperature under a certain moisture content, condensation will occur. Therefore, when there is a first lowest temperature less than or equal to the dew point temperature, the dehumidifier is started to prevent condensation; in addition, the spare space of the energy storage system is small, so a semiconductor dehumidifier is usually used. This dehumidifier is small in volume but has the defect of a short service life, and it is also an energy-consuming component. In this case of precise control, the unnecessary startup duration of the dehumidifier can be reduced, the service life of the dehumidifier can be extended, the energy consumption can be reduced, and the dehumidification effect can be ensured.

[0057] On the other hand, sometimes the energy storage cabinet will be opened for debugging, and external moisture will directly enter, resulting in a sudden increase in air humidity. To prevent condensation, the dehumidifier is directly started. Optionally, the humidity threshold can be 60%.

[0058] In an optional embodiment, after controlling the dehumidifier to start when the first lowest temperature point is less than or equal to the dew point temperature, it further includes: obtaining the second lowest temperature point among the temperatures detected by the temperature and humidity sensors in the sensor area; when the second lowest temperature point is greater than the dew point temperature, setting the dehumidifier to stop working after running for a preset duration from the current moment. When the second lowest temperature point is greater than the dew point temperature, it indicates that there is no current condensation risk, and at this time, the dehumidifier can be turned off. This solution sets a redundant preset duration to turn off the dehumidifier, which can fully dehumidify the inside of the energy storage box and ensure the dehumidification effect inside the energy storage box.
