Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of energy storage containers, and in particular to an anti-condensation control method for energy storage containers. Background Art

[0002] The energy storage container integrates a battery cluster formed by a large number of batteries connected in series and parallel and a power storage inverter (PCS). The battery cluster is set in the battery compartment of the container, and the energy storage inverter (PCS) is set in the equipment compartment of the energy storage container to control and manage the charging and discharging of the battery cluster.

[0003] The equipment compartment of the energy storage container is equipped with a temperature and humidity sensor and an air conditioner. The air conditioner in the equipment compartment keeps the temperature and humidity in the equipment compartment within an appropriate range. The temperature and humidity sensor detects the temperature and humidity inside the equipment compartment in real time. When the temperature and humidity in the equipment compartment do not meet the requirements, the heating, cooling and dehumidification functions of the air conditioner are used to restore the temperature and humidity in the equipment compartment to an appropriate range.

[0004] The inventors of the present application have discovered that the energy storage converter (PCS) needs to open the container door and the equipment compartment door for processing during equipment maintenance, inspection, fault repair and certain abnormal situations. Due to the difference in temperature and humidity between the inside and outside of the energy storage container, the energy storage converter (PCS) that is in a stopped state is prone to condensation during the opening of the equipment compartment door. After the equipment compartment door is closed, if the stopped energy storage converter (PCS) is immediately connected to the grid and put into operation, the presence of condensation will damage the energy storage converter (PCS), affect its performance and life, and even cause safety hazards; and if only relying on automatic temperature control and dehumidification of the equipment compartment air conditioner, it will take a long time for the temperature and humidity in the equipment compartment to return to the appropriate range.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0068] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0069] As described in the background technology of this application, a temperature and humidity sensor and an air conditioner are provided in the equipment compartment of the energy storage container. The temperature and humidity sensor detects the temperature and humidity inside the equipment compartment in real time. When the temperature and humidity in the equipment compartment do not meet the regulations, the heating, cooling and dehumidification functions of the air conditioner are used to restore the temperature and humidity in the equipment compartment to an appropriate range.

[0070] The inventors of the present application have discovered that the energy storage converter (PCS) needs to open the container door and the equipment compartment door for processing during equipment maintenance, inspection, fault repair and certain abnormal situations. Due to the difference in temperature and humidity between the inside and outside of the energy storage container, the energy storage converter (PCS) that is in a stopped state is prone to condensation during the opening of the equipment compartment door. After the equipment compartment door is closed, if the stopped energy storage converter (PCS) is immediately connected to the grid and put into operation, condensation will damage the energy storage converter (PCS), affect its performance and life, and even cause safety hazards to the energy storage container; and if the equipment compartment air conditioner is relied upon for automatic temperature control and dehumidification, it will take a long time for the temperature and humidity in the equipment compartment to return to the appropriate range.

[0071] In order to solve the above problems, the inventor of the present application proposed the technical solution of the present application, and the specific embodiments are as follows:

[0072] Figure 1 is a flow chart of the anti-condensation control method for an energy storage container in an embodiment of the present invention, Figure 2 is a flow chart of anti-condensation in the state where the equipment compartment door is open in an embodiment of the present invention, Figure 3 This is a flow chart for preventing condensation when the equipment compartment door is closed in an embodiment of the present invention.

[0073] like Figures 1 to 3 As shown, the anti-condensation control method for the energy storage container of this embodiment includes the following steps:

[0074] S1 obtains the temperature and humidity data inside the equipment cabin and the temperature and humidity data of the external environment;

[0075] S2 The equipment cabin air conditioner executes the corresponding preset operation mode according to the temperature and humidity data inside the equipment cabin;

[0076] S3 obtains the open / closed status of the equipment door lock;

[0077] S4 obtains the communication status of the equipment cabin air conditioner and the equipment cabin temperature and humidity sensor;

[0078] S5 executes the corresponding anti-condensation strategy according to the equipment compartment door lock status and the communication status of the equipment compartment air conditioner and the equipment compartment temperature and humidity sensor.

[0079] In this embodiment, high-precision and high-sensitivity temperature sensors and humidity sensors are reasonably arranged in the energy storage container. The temperature and humidity sensors collect real-time temperature and humidity data inside the container and inside the equipment compartment of the container, and ensure the accuracy and comprehensiveness of the collected data. At the same time, the temperature and humidity of the external environment of the container are monitored at a sampling frequency of once per second, so as to timely grasp the impact of external environmental changes on the interior of the container.

[0080] Before the energy storage container is put into operation, a suitable temperature and humidity strategy should be formulated. During the operation of the energy storage container, the temperature and humidity in the equipment cabin should be kept within the appropriate required range through the equipment cabin air conditioning.

[0081] The equipment compartment air conditioner is preset with multiple operating modes. During the operation of the container, the temperature and humidity sensor obtains the real-time temperature and humidity data inside the equipment compartment, and according to the real-time temperature and humidity data in the equipment compartment, the equipment compartment air conditioner executes the corresponding preset operating mode. When the temperature and humidity data in the equipment compartment changes, the temperature and humidity data in the equipment compartment are restored to the appropriate required range as soon as possible to prevent condensation as much as possible and reduce energy consumption as much as possible.

[0082] During the operation of the energy storage container, the control module collects the opening and closing status of the equipment compartment door lock in the container, and the communication status of the equipment compartment air conditioner and the equipment compartment temperature and humidity sensor. According to the opening and closing status of the equipment compartment door lock, and the communication status of the equipment compartment air conditioner and the equipment compartment temperature and humidity sensor, the corresponding anti-condensation strategy is executed for the PCS (energy storage inverter) in the equipment compartment, thereby achieving effective prevention of condensation and preventing damage to the PCS due to the presence of condensation.

[0083] It should be noted that the humidity described in this patent application refers to relative humidity.

[0084] It is not difficult to find from the above content that the energy storage container anti-condensation control method of this embodiment, during the operation of the energy storage container, the temperature and humidity data in the equipment cabin are obtained through the temperature and humidity sensor, and the equipment cabin air conditioner executes the corresponding preset operation mode according to the real-time temperature and humidity data in the equipment cabin; and during the operation of the energy storage container, according to the opening and closing status of the equipment cabin door lock, and the communication status of the equipment cabin air conditioner and the temperature and humidity sensor, the corresponding anti-condensation strategy is executed for the PCS in the equipment cabin, so as to achieve effective prevention of condensation and prevent the PCS from being damaged due to the presence of condensation.

[0085] Optional, such as Figure 2 and Figure 3 As shown, the energy storage container anti-condensation control method in this embodiment, in step S5, executes the corresponding anti-condensation strategy according to the equipment compartment door lock state, and the communication state of the equipment compartment air conditioner and the equipment compartment temperature and humidity sensor, specifically including:

[0086] S51 If the equipment compartment door lock is in the open state (equipment compartment door is open) and the temperature and humidity sensor communication in the equipment compartment is abnormal, the grid connection prohibition sign is triggered. At this time, the non-operating PCS in the equipment compartment is prohibited from grid connection to prevent the PCS from being damaged due to the presence of condensation.

[0087] S52 If the equipment compartment door lock is in the open state (equipment compartment door is open), the temperature and humidity sensors in the equipment compartment communicate normally, and the humidity abnormality flag in the equipment compartment is 1 (humidity abnormality flag is triggered), then the grid connection prohibition flag is triggered. At this time, the non-operating PCS in the equipment compartment is prohibited from being connected to the grid.

[0088] S53 If the equipment compartment door lock is in the closed state (the equipment compartment door is closed), and the equipment compartment air conditioner and the temperature and humidity sensors in the equipment compartment are communicating abnormally, the grid connection prohibition sign is triggered. At this time, the non-operating PCS in the equipment compartment is prohibited from being connected to the grid to prevent the PCS from being damaged due to the presence of condensation.

[0089] S54 If the equipment compartment door lock is in the closed state (equipment compartment door is closed), the temperature and humidity sensor communication in the equipment compartment is normal, the equipment compartment air conditioning communication is abnormal, and the humidity abnormality flag in the equipment compartment is 1 (the humidity abnormality flag is triggered), then the grid connection prohibition flag is triggered. At this time, the non-operating PCS in the equipment compartment is prohibited from connecting to the grid.

[0090] S55 If the equipment compartment door lock is in the closed state (equipment compartment door is closed), the equipment compartment air conditioning communication is normal, and the temperature and humidity sensor communication is abnormal, the anti-condensation mark is triggered. At this time, the non-operating PCS in the equipment compartment is prohibited from being connected to the grid.

[0091] S56 If the equipment compartment door lock is in the closed state (equipment compartment door is closed), the equipment compartment air conditioning communication is normal, the temperature and humidity sensor communication is normal, and the humidity abnormality flag is 1 (the humidity abnormality flag is triggered), the anti-condensation flag is triggered. At this time, the non-operating PCS in the equipment compartment is prohibited from being connected to the grid.

[0092] Furthermore, the energy storage container anti-condensation control method in this embodiment, in step S55, further includes:

[0093] S551 After the equipment compartment air conditioner has been running for 10 minutes, the PCS spoiler fan will be run at full speed for another 10 minutes. At this time, the non-running PCS is allowed to start.

[0094] That is, if the equipment compartment door lock is closed (the equipment compartment door is closed), the equipment compartment air conditioning communication is normal, and the temperature and humidity sensor communication is abnormal, the anti-condensation mark is triggered, and the non-operating PCS in the equipment compartment is prohibited from connecting to the grid. Then, after the equipment compartment air conditioning has been running for 10 minutes, and on the basis of keeping the equipment compartment air conditioning running, the spoiler fan of the non-operating PCS is turned on and runs at full speed. After the PCS spoiler fan runs at full speed for 10 minutes, the non-operating PCS is allowed to start and connect to the grid.

[0095] In step S56, it also includes:

[0096] S561 runs the equipment room air conditioner for 10 minutes, and then runs the PCS spoiler fan at full speed until the humidity abnormality mark disappears. The non-operating PCS is allowed to start and connect to the grid.

[0097] That is, if the equipment compartment door lock is in the closed state (the equipment compartment door is closed), the communication of the equipment compartment air conditioner is normal, the communication of the temperature and humidity sensor is normal, and the humidity anomaly flag is 1, then the anti-condensation flag is triggered. At this time, the non-operating PCS in the equipment compartment is prohibited from being connected to the grid. Then, after the equipment compartment air conditioner has been running for 10 minutes and continues to run, the spoiler fan of the non-operating PCS is started to run at full speed until the humidity anomaly flag disappears. At this time, the non-operating PCS is allowed to start and be connected to the grid for operation.

[0098] Furthermore, in the anti-condensation control method of the energy storage container in this embodiment, if one of the following conditions is met and the duration is greater than 10 seconds, the humidity anomaly flag is triggered (the humidity anomaly flag is 1); when the conditions are not met, the zero-clearing and broadening time of the humidity anomaly flag is also 10 seconds.

[0103] Optionally, in the anti-condensation control method of the energy storage container in this embodiment, in step S2, the equipment compartment air conditioner executes the corresponding preset operation mode according to the temperature and humidity data inside the energy storage container, specifically including:

[0104] S21 When the internal temperature of the equipment compartment is higher than 28°C (T>T3) and the internal humidity of the equipment compartment is lower than 42% (RH<RH4), the equipment compartment air conditioner operates in the strong refrigeration mode.

[0105] S22 When the internal temperature of the equipment compartment is higher than 28°C (T>T3) and the internal humidity of the equipment compartment is between 42% and 68% (RH4≤RH≤RH5), the equipment compartment air conditioner operates in the standard refrigeration mode.

[0106] S23 When the internal temperature of the equipment compartment is higher than 28°C (T>T3) and the internal humidity of the equipment compartment is greater than 68% (RH>RH5), the equipment compartment air conditioner operates in the strong dehumidification and refrigeration mode.

[0121] In step S28, the high-power heating mode is: the heating power of the equipment compartment air conditioner is adjusted to 88% of the rated power of the air conditioner, and the air volume is adjusted to 82% of the maximum air volume to prevent the temperature in the equipment compartment from being too low and affecting the operation of the equipment.

[0122] In step S29, the standard heating mode is: the heating power of the equipment compartment air conditioner is adjusted to 72% of the rated power of the air conditioner, and the air volume is adjusted to 68% of the maximum air volume to provide a suitable temperature environment.

[0123] Furthermore, the energy storage container anti-condensation control method in this embodiment also includes: according to the dew point temperature calculation formula, real-time calculation and acquisition of the dew point temperature in the equipment compartment, and according to the difference between the dew point temperature and the internal temperature of the equipment compartment, dynamically adjusting the cooling capacity, dehumidification capacity and air volume power of the equipment compartment air conditioner to prevent the generation of condensation and ensure the operation of the equipment.

[0124] The dew point calculation formula is:

[0125] T d =C1×[ln(RH / 100)+((C2×T) / (C1+T))] / [C2-ln(RH / 100)-((C2×

[0126] T) / (C1+T))]

[0127] Among them, Td is the real-time dew point temperature of the equipment cabin (°C), RH is the measured humidity of the equipment cabin (%), T is the measured internal temperature of the equipment cabin (°C), C1 and C2 are coefficients, C1 is 243.04, and C2 is 17.625.

[0128] Based on the real-time temperature and humidity of the equipment cabin, the dew point temperature inside the equipment cabin can be calculated in real time, and then the cooling capacity, dehumidification capacity and air volume of the equipment cabin air conditioner can be dynamically adjusted to prevent condensation.

[0129] Furthermore, the anti-condensation control method for the energy storage container in this embodiment, wherein the cooling capacity, dehumidification capacity and air volume of the equipment compartment air conditioner are adjusted according to the difference between the dew point temperature and the internal temperature of the equipment compartment, specifically includes:

[0130] If △T<T5, the air conditioning cooling capacity increases by 28%, the dehumidification capacity increases by 22%, and the air volume increases to 90% of the maximum air volume.

[0131] If T5≤△T<T6, the air conditioning cooling capacity increases by 12%, the dehumidification capacity increases by 8%, and the air volume increases to 72% of the maximum air volume.

[0132] If △T≥T6, the air conditioner maintains the current operating parameters to ensure the stability and reliability of the air conditioner operation.

[0133] Among them, △T is the difference between the dew point temperature and the internal temperature of the equipment compartment, T5 is the first preset difference, and T6 is the second preset difference.

[0134] Optionally, in the anti-condensation control method for the energy storage container in this embodiment, the acquired temperature and humidity data inside the equipment compartment are obtained after first-order low-pass filtering, that is, the temperature and humidity detected by the temperature and humidity sensor are uploaded after first-order low-pass filtering to ensure the accuracy of the temperature and humidity data.

[0136] Moreover, the first feature being “above”, “above”, and “above” the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being “below”, “below”, and “below” the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
