DETAILED DESCRIPTION

[0024] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0025] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0026] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0027] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0028] Figure 1 This is a schematic diagram of the structure of an energy storage device provided in an embodiment of the present application. Figure 1 As shown, the device may include: a temperature and humidity sensor, a central control unit, and an adjustment unit. The temperature and humidity sensors are arranged in multiple key areas inside and outside the battery compartment, and are used to collect temperature and humidity data of key areas of the battery compartment, and send the temperature and humidity data to the central control unit. The central control unit can be regarded as the core "brain" of the energy storage device, which receives the temperature and humidity data sent by each temperature and humidity sensor, and sends the corresponding adjustment signal to the adjustment unit according to the preset control strategy, controls the operation of the adjustment unit, and realizes the precise adjustment of the temperature and humidity of the battery compartment.

[0029] The regulating unit may include: a refrigeration unit, a heating unit, a dehumidification unit and a humidification unit. For example, the refrigeration unit may be composed of a compressor, a condenser, an evaporator and the like to form a refrigeration cycle system, and in response to the refrigeration signal sent by the central control unit, it is started when the temperature of the battery compartment is too high to quickly reduce the temperature in the cabin. For example, the heating unit may be equipped with an electric heater or a hot air blower, and in response to the heating signal sent by the central control unit, it is turned on in a low temperature environment to increase the temperature in the cabin and ensure that the temperature in the cabin is always in a preset reasonable range. For example, the dehumidification unit may be built-in with a dehumidifier or a desiccant box, and in response to the dehumidification signal sent by the central control unit, the dehumidifier dehumidifies by refrigeration principle or wheel adsorption, and the desiccant box is filled with high-efficiency hygroscopic materials to continuously absorb excess moisture in the cabin. For example, the humidification unit may be an ultrasonic humidifier or a wet film humidifier, and in response to the humidification signal sent by the central control unit, when the humidity in the cabin is low, the air humidity is moderately increased to maintain the humidity balance in the cabin.

[0030] In an optional embodiment, the central control unit may determine the temperature and humidity of the battery compartment based on the temperature and humidity data of different key areas and the corresponding regional weights; and when the temperature and humidity of the battery compartment exceed the temperature and humidity thresholds, the central control unit sends a corresponding adjustment signal to the adjustment unit. Specifically, different key areas are configured with different regional weights, and the regional weights are pre-stored in the storage space of the central control unit. After the central control unit receives the temperature and humidity data of each key area sent by each temperature sensor, it obtains the regional weight of each key area in the storage space, multiplies the temperature and humidity data of each conceptual area by the corresponding regional weight and sums them up to obtain the battery compartment temperature and humidity. The battery compartment temperature and humidity can be used to characterize the overall temperature and humidity in the current battery compartment.

[0031] In an optional embodiment, the key areas of the battery compartment can be divided into central areas or non-central areas based on the distance between each key area and the core working area of ​​the battery pack. The central area can be configured with a higher area weight, and the non-central area can be configured with a lower area weight.

[0032] Reference Figure 2 , a battery pack 22 is arranged inside the battery compartment 21, and a temperature and humidity sensor 23, a heating unit 24, a cooling unit 25, a humidification unit 26 and a dehumidification unit 27 are arranged in appropriate positions, and the central control unit is not shown. The battery compartment adopts an all-round sealing design, and uses high-quality sealing strips and sealants to ensure the sealing of the cabin; at the same time, insulating materials are laid on the inner wall of the cabin to prevent condensed water from conducting electricity and causing safety accidents. Inside the battery compartment, temperature and humidity sensors are respectively arranged above, in the middle and below the battery pack to comprehensively monitor the temperature and humidity changes of the battery pack at different heights. The temperature and humidity sensor arranged above the battery pack can timely sense the impact of the heat generated by the battery pack during charging or discharging on the temperature and humidity of the upper air in the cabin; the temperature and humidity sensor in the middle position can monitor the temperature and humidity of the core area of ​​the battery pack; the temperature and humidity sensor at the bottom helps to detect humidity abnormalities caused by condensed water that may accumulate at the bottom.

[0033] For temperature data, the temperature and humidity sensor in the middle position can better reflect the temperature of the core working area of ​​the battery pack, and a higher regional weight can be configured for this key area. The temperature and humidity sensors in the upper and lower positions are relatively far away from the core working area of ​​the battery pack, and a lower regional weight can be configured for this key area. For example, the regional weight of the middle position is set to 0.5, and the regional weights of the upper and lower positions are both set to 0.25.

[0034] For humidity data, condensation is likely to accumulate in the lower part of the battery compartment after it occurs, so a higher regional weight can be configured for this key area. Whether the humidity in the middle position is reasonable directly affects the health of the battery pack, so this key area can also be configured with a higher regional weight. The humidity in the upper position has little effect on the battery pack, so a lower regional weight can be configured for this key area. For example, set the regional weights of the middle and lower positions to 0.4, and set the regional weight of the upper position to 0.2.

[0035] In an embodiment of the present application, through average weighted calculation, the central control unit can more accurately calculate the comprehensive temperature value or comprehensive humidity value that reflects the actual temperature and humidity conditions of the battery compartment, thereby providing more reliable data support for subsequent temperature control decisions or humidity control decisions.

[0036] The temperature control decision of the central control unit may include two aspects: cooling and dehumidification and heating and warming.

[0037] (1) Refrigeration and dehumidification When the battery compartment temperature exceeds the upper temperature limit, the central control unit sends a refrigeration signal to the refrigeration unit and a dehumidification signal to the dehumidification unit. The refrigeration unit responds to the refrigeration signal and performs a cooling operation until the battery compartment temperature drops below the upper temperature limit. The dehumidification unit responds to the dehumidification signal and performs a dehumidification operation during the operation of the refrigeration unit. Condensation is prone to occur in an environment with high temperature and humidity, and the battery pack being in a high temperature and high humidity environment will affect its service life and working performance. During the cooling operation of the refrigeration unit, the water vapor in the battery compartment is easily liquefied when it is cooled. The dehumidification unit needs to cooperate with the refrigeration unit to perform the dehumidification operation to reduce the conditions for condensation from the source and ensure that the battery pack works in a suitable environment.

[0038] (2) Heating When the battery compartment temperature is lower than the lower temperature limit, the central control unit sends a heating signal to the heating unit. The heating unit responds to the heating signal and performs a heating operation until the battery compartment temperature rises above the lower temperature limit. A low temperature inside the battery compartment will affect the normal operation of the battery pack, and a large temperature difference between the inside and outside of the battery compartment may cause condensation. Adjusting the temperature by the heating unit can ensure that the battery pack is in a suitable temperature environment and avoid condensation.

[0039] The humidity control decision of the central control unit may include two aspects: dehumidification and drying and humidification and moisturizing.

[0040] (1) Dehumidification and drying When the humidity in the battery compartment exceeds the upper humidity limit, a dehumidification signal is sent to the dehumidification unit. In response to the dehumidification signal, the dehumidification unit performs a dehumidification operation until the humidity in the battery compartment drops below the upper humidity limit. By removing excess moisture in the battery compartment, the conditions for condensation to occur are changed.

[0041] (2) Humidification and moisturizing When the humidity in the battery compartment is lower than the lower humidity limit, a humidification signal is sent to the humidification unit. In response to the humidification signal, the humidification unit performs a humidification operation until the humidity in the battery compartment rises above the lower humidity limit. By releasing water molecules, the humidity in the compartment is increased, and a suitable humidity environment is maintained to prevent the battery pack from being damaged due to excessive drying.

[0042] In the embodiment of the present application, the temperature and humidity thresholds may include an upper temperature limit, a lower temperature limit, an upper humidity limit, and a lower humidity limit. The upper temperature limit and the lower temperature limit cover a temperature range, and the upper humidity limit and the lower humidity limit cover a humidity range. The temperature and humidity of the battery compartment may include the battery compartment temperature or the battery compartment humidity. When the battery compartment temperature exceeds the temperature range or the battery compartment humidity exceeds the humidity range, the central control unit instructs the adjustment unit to adjust the temperature or humidity in the compartment to ensure that the battery pack works in a suitable temperature and humidity environment. For example, the temperature range can be set to 15-30°C, and the humidity range can be set to 40%-60%RH. During the battery charging process, the temperature and humidity sensor collects temperature and humidity data inside and outside the cabin every 5 minutes. At a certain moment, the central control unit calculates that the battery compartment temperature is 35°C and the battery compartment humidity is 70%RH, and controls the refrigeration unit and the dehumidification unit to run simultaneously. After 30 minutes of adjustment, the battery compartment temperature drops to 25°C and the battery compartment humidity drops to 50%RH. During the subsequent charging and discharging operation, the device continuously monitors and controls, automatically heats and heats in a low temperature environment, and strengthens dehumidification in a humid environment to ensure that the battery pack is in the best condition throughout the process.

[0043] In an optional embodiment, when the temperature and humidity of the battery compartment exceed the temperature and humidity threshold, the central control unit can dynamically adjust the operating power of the adjustment unit based on the extent to which the temperature and humidity of the battery compartment exceed the temperature and humidity threshold. Specifically, when the temperature and humidity of the battery compartment exceed the temperature and humidity threshold, the central control unit determines the temperature and humidity difference between the temperature and humidity of the battery compartment and the temperature and humidity threshold, and determines the operating power of the adjustment unit based on the temperature and humidity difference, wherein the greater the temperature and humidity difference, the greater the corresponding operating power. Afterwards, the central control unit sends an adjustment signal including the operating power to the adjustment unit.

[0044] For example, when the battery compartment temperature exceeds the preset temperature upper limit (30°C), the central control unit dynamically adjusts the operating power of the refrigeration unit according to the extent of the excess. If the battery compartment temperature exceeds the temperature upper limit by less than 5°C (such as 35°C), the refrigeration unit can be instructed to operate at low power (such as 40% of the rated power) to reduce the temperature in the cabin in a more gentle way to avoid energy waste due to excessive cooling. If the battery compartment temperature exceeds the temperature upper limit by more than 10°C (such as 40°C), the refrigeration unit can be instructed to operate at high power (such as 80% of the rated power) to quickly reduce the temperature to a safe range to ensure that the battery pack will not be damaged due to being in a high temperature environment for a long time. Similarly, for humidity control, when the battery compartment humidity exceeds the humidity upper limit (60%RH), the central control unit adjusts the operating power of the dehumidification unit according to the degree of excess. If the battery compartment humidity exceeds the humidity upper limit by less than 10%RH, the dehumidification unit can be instructed to operate at low power. If the battery compartment humidity exceeds the humidity upper limit by more than 10%RH, the operating power of the dehumidification unit is increased to speed up the dehumidification speed.

[0045] In an optional embodiment, the operating power of the regulating unit can also be dynamically adjusted based on time changes, and different control strategies can be formulated according to the environmental conditions and battery pack working status in different time periods. For example, at night or during periods with low ambient temperatures, the operating time of the heating unit is reduced or its operating power is reduced; during the day or during periods with high ambient temperatures, the operating power of the cooling unit and the dehumidification unit is reasonably adjusted to meet actual needs and avoid unnecessary energy consumption.

[0046] In the embodiment of the present application, by dynamically adjusting the operating power of the regulation unit, the safe and stable operation of the battery pack can be guaranteed, and energy waste can be avoided, which is in line with the development trend of green energy conservation.

[0047] In an optional embodiment, the central control unit can also dynamically adjust the temperature and humidity thresholds based on the battery remaining value SOC (State of Charge) so that the temperature and humidity adjustment meets different scenarios. Specifically, the central control unit obtains the battery remaining value of the current battery compartment in real time, and dynamically adjusts the temperature and humidity thresholds based on the battery remaining value. The adjustment method may include: when the battery remaining value decreases, increasing the upper limit value of temperature and humidity or / and decreasing the lower limit value of temperature and humidity; when the battery remaining value increases, decreasing the upper limit value of temperature and humidity or / and increasing the lower limit value of temperature and humidity.

[0048] For example, when the battery remaining value is high (such as greater than 80%), it means that the battery pack may be in a state of being about to be fully charged or just fully charged. At this time, the chemical reaction inside the battery pack is relatively active and more sensitive to the ambient temperature and humidity. To ensure battery safety, the central control unit appropriately narrows the temperature and humidity threshold range, such as adjusting the upper temperature limit from 30°C to 28°C and the upper humidity limit from 60%RH to 55%RH, so as to more strictly control the temperature and humidity in the cabin and avoid potential impact on the battery due to slightly higher temperature and humidity. On the contrary, when the battery remaining value is low (such as less than 30%), the battery pack is relatively less sensitive to the environment, and the central control unit can appropriately relax the temperature and humidity threshold range, such as the upper temperature limit can be relaxed to 32°C and the upper humidity limit can be relaxed to 65%RH.

[0049] In the embodiment of the present application, in response to changes in the battery remaining value, the central control unit dynamically adjusts the temperature and humidity thresholds, which can reduce unnecessary energy consumption for temperature and humidity control while ensuring the safety of the battery pack.

[0050] In an optional embodiment, the device can also use the natural environment to adjust the temperature and humidity. A vent is designed on the battery compartment. When the temperature and humidity of the environment outside the cabin are suitable, natural ventilation is used for ventilation to reduce the energy consumption of the device itself. For example, when the air outside the cabin is dry and the temperature is moderate, the hot and humid air in the cabin is discharged through ventilation equipment, and dry air is introduced to reduce the humidity in the cabin, while saving the operating energy consumption of the dehumidification unit. For another example, when the outside humidity is low, the humidity in the cabin is first reduced by ventilation instead of relying on humidification equipment, thereby saving energy.

[0051] In an optional embodiment, the central control unit can also perform predictive analysis based on historical data and perform temperature and humidity control in advance. Data analysis and predictive modeling are performed based on the long-term accumulated temperature and humidity data and battery pack operation data. The model can predict the heat generation and humidity change trends of the battery pack under different working conditions, and the central control unit can adjust the operating parameters of the adjustment unit in advance. For example, the model predicts that the heat generation of the battery pack will increase in the near future. The central control unit can instruct the refrigeration unit and the dehumidification unit to operate at low power in advance to smoothly reduce the temperature and humidity of the battery compartment. If the temperature and humidity are adjusted only after the battery pack generates a surge in heat, in order to ensure the safety of the battery pack, the refrigeration unit and the dehumidification unit usually need to operate at high power, which increases the energy consumption of the device.

[0052] In the embodiment of the present application, by predicting the changing trend of the temperature and humidity in the battery compartment and starting the temperature and humidity adjustment in advance, high energy consumption adjustment caused by sudden changes in temperature and humidity can be avoided, ensuring that the battery pack is in a relatively stable temperature and humidity environment, thereby increasing the life of the battery pack and saving energy consumption.

[0053] In an optional embodiment, the central control unit can also optimize the operating mode of temperature and humidity regulation according to the battery life cycle and aging degree. For example, for newer battery packs, the central control unit can appropriately relax the range covered by the temperature and humidity thresholds, thereby reducing the frequency of regulation and avoiding energy waste caused by frequent activation of the regulation unit. For aging battery packs, the central control unit can appropriately narrow the range covered by the temperature and humidity thresholds, increase the regulation accuracy, ensure that the battery pack works in a good environment, and extend the battery life.

[0054] In the embodiment of the present application, the central control unit dynamically adjusts the operating parameters of each adjustment unit according to real-time data, such as cooling power, heating power, dehumidification intensity, humidification amount, etc., to ensure that the temperature and humidity of the battery compartment are always stable within the optimal anti-condensation range. The various units of the energy storage device work together to avoid excessive use of a single module. For example, when it is necessary to adjust the temperature and humidity at the same time, the refrigeration unit and the dehumidification unit can be operated jointly, and the condensation and dehumidification effect during the refrigeration process can be used to achieve cooling and dehumidification at the same time, thereby improving energy utilization efficiency.

[0055] Through the above-mentioned embodiments, the energy storage device ensures that the temperature and humidity in the battery compartment are within an appropriate range and prevents condensation, while achieving efficient use of energy, reducing the operating cost of the system and improving the overall energy-saving efficiency.

The method can be applied to the above energy storage device, such as Figure 3 As shown, the method may include: Step 301, obtaining temperature and humidity data of key areas of the battery compartment and area weights corresponding to each key area.

[0057] Step 302: Determine the temperature and humidity of the battery compartment based on the temperature and humidity data of each key area and the corresponding area weight.

[0058] Step 303: When the temperature and humidity of the battery compartment exceed the temperature and humidity threshold, a corresponding adjustment signal is sent to the adjustment unit so that the adjustment unit adjusts the temperature and humidity of the battery compartment.

[0059] The temperature and humidity at different positions in the battery compartment have different effects on the working state of the battery pack and the generation of condensation. The embodiment of the present application sets the temperature and humidity sensors in multiple key areas and sets different area weights for each key area. A more accurate battery compartment temperature and humidity can be obtained through a weighted average algorithm, and then the temperature and humidity are adjusted to avoid condensation in the battery compartment and ensure the safe operation of the battery pack.

[0065] Step 404: the regulating unit performs temperature and humidity regulation.

[0066] The regulating unit includes: a heating unit, a cooling unit, a dehumidifying unit and a humidifying unit. When the battery compartment temperature is greater than the upper temperature limit, the cooling unit performs a cooling operation. When the battery compartment temperature is less than the lower temperature limit, the heating unit performs a heating operation. When the battery compartment humidity exceeds the upper humidity limit, the dehumidifying unit performs a dehumidifying operation. When the battery compartment humidity is lower than the lower humidity limit, the humidifying unit performs a humidifying operation.
