[0023] As introduced in the background technology, as the energy density of batteries increases, more and more energy storage cabinets use liquid cooling units for cooling. While the liquid cooling unit brings a larger cooling capacity, the condensation problem of the liquid cooling plate in the battery compartment is becoming more and more prominent. In summer, the air temperature and humidity inside the liquid cooling unit are high, and the liquid supply temperature of the liquid cooling unit is between 15 and 25°C, which is often lower than the dew point temperature of the air. At this time, condensation water will be generated on the surface of the liquid cooling plate. In severe cases, the water will slide down, affecting the safe operation of the battery compartment. In order to solve the problem that the existing solution cannot reduce the amount of condensation water generated by the liquid cooling plate in the battery compartment of the liquid cooling unit, thereby affecting the safe operation of the battery compartment, the embodiments of the present application provide an anti-condensation control method, medium and system for an energy storage cabinet.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] In this embodiment, a method for controlling condensation prevention of an energy storage cabinet is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0026] Figure 1 FIG. 1 is a flow chart of an anti-condensation control method for an energy storage cabinet provided according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0027] Step S101, obtaining the abnormal high temperature of the liquid supply and the initial liquid supply setting temperature of the liquid cooling unit of the energy storage cabinet, and obtaining the air dew point temperature at the current moment to obtain a first dew point temperature, wherein the abnormal high temperature of the liquid supply represents the temperature limit for preventing abnormal liquid supply of the liquid cooling unit;

[0028] Specifically, the abnormal temperature of the liquid supply high temperature ranges from 25°C to 40°C;

[0029] Step S102, determining a final liquid supply setting temperature according to the abnormal liquid supply high temperature, the initial liquid supply setting temperature and the first dew point temperature, and controlling the operation of the liquid cooling unit with the final liquid supply setting temperature.

[0030] In the above steps, the first dew point temperature is obtained by obtaining the abnormal high-temperature liquid supply temperature and the initial liquid supply setting temperature of the liquid cooling unit of the energy storage cabinet, and obtaining the air dew point temperature at the current moment. Finally, the final liquid supply setting temperature is determined according to the abnormal high-temperature liquid supply temperature, the initial liquid supply setting temperature and the first dew point temperature, so that it is difficult for the liquid cooling plate in the battery compartment of the liquid cooling unit to produce condensation, thereby reducing the amount of condensation water generated by the liquid cooling plate in the battery compartment of the liquid cooling unit compared to the existing solution, thereby solving the problem that the existing solution cannot reduce the amount of condensation water generated by the liquid cooling plate in the battery compartment of the liquid cooling unit, thereby affecting the safe operation of the battery compartment.

[0031] The step S102 of determining the final set liquid supply temperature according to the abnormal high temperature of the liquid supply, the initial set liquid supply temperature and the first dew point temperature includes:

[0032] Determine a temperature sum value and a temperature difference value, wherein the temperature sum value is the sum of the first dew point temperature and the first preset temperature, and the temperature difference value is the difference between the abnormal high temperature of the liquid supply and the second preset temperature;

[0033] The final liquid supply set temperature is determined to be the minimum value among the initial liquid supply set temperature, the temperature sum and the temperature difference.

[0034] Specifically, the first preset temperature is 2°C, and the second preset temperature is 1°C.

[0035] In the case where the initial liquid supply setting temperature is greater than or equal to the sum of the first dew point temperature and the first preset temperature, and the initial liquid supply setting temperature is less than or equal to the difference between the abnormal liquid supply high temperature temperature and the second preset temperature, the final liquid supply setting temperature is determined to be the initial liquid supply setting temperature, and the second preset temperature is less than the first preset temperature;

[0036] When the initial liquid supply setting temperature is less than the sum of the first dew point temperature and the first preset temperature, and the sum of the first dew point temperature and the first preset temperature is less than the difference between the abnormal high temperature of the liquid supply and the second preset temperature, the final liquid supply setting temperature is determined to be the sum of the first dew point temperature and the first preset temperature;

[0037] When the initial liquid supply setting temperature is less than the difference between the abnormal liquid supply high temperature and the second preset temperature, and the difference between the abnormal liquid supply high temperature and the second preset temperature is less than the difference between the sum of the first dew point temperature and the first preset temperature, the final liquid supply setting temperature is determined to be the difference between the abnormal liquid supply high temperature and the second preset temperature.

[0038] Through the above-mentioned determination process, the final liquid supply setting temperature is selected as low as possible to prevent condensation. After the energy storage cabinet is in operation, the battery pack generates heat after charging and discharging. At this time, the liquid cooling unit needs to be turned on to cool the coolant. The cooled coolant is transported to the battery pack cold plate to cool the battery pack.

[0039] In one embodiment of the present application, the above method further includes:

[0040] When the final liquid supply set temperature is determined to be the temperature and value, the liquid cooling unit is controlled to operate for a first preset time (i.e., 15 minutes) at the final liquid supply set temperature;

[0041] During the first preset time period, a first temperature difference value and a liquid supply temperature change rate are obtained, wherein the first temperature difference value is the difference between the final liquid supply setting temperature and the actual liquid supply temperature, the actual liquid supply temperature is the actual measured liquid supply temperature when the liquid cooling unit is controlled to run for the first preset time period at the final liquid supply setting temperature, and the liquid supply temperature change rate is the change rate of the actual liquid supply temperature of the liquid cooling unit within the second preset time period (i.e., 1 minute);

[0042] Determine a supply liquid temperature determination value according to the first temperature difference value, the supply liquid temperature change rate, the supply liquid temperature difference coefficient and the supply liquid temperature change rate coefficient;

[0043] The change rate of the liquid supply temperature is the change rate of the liquid supply temperature within 1 minute after the liquid cooling unit has been running at the final liquid supply setting temperature for a first preset time.

[0044] The value range of the supply liquid temperature difference coefficient is 0.1-10, and the value range of the supply liquid temperature change rate coefficient is 0.3-5.

[0045] Specifically, determine a first product and a second product, the first product being the product of the first temperature difference value and the liquid supply temperature difference coefficient, and the second product being the product of the liquid supply temperature change rate and the liquid supply temperature change rate coefficient; determine the liquid supply temperature judgment value as the sum of the first product and the second product.

[0046] According to the size of the above-mentioned liquid supply temperature judgment value, it is determined that no condensation is generated on the liquid cooling plate in the battery compartment of the above-mentioned liquid cooling unit, or at least part of all the dehumidification equipment is controlled to start dehumidification work to reduce condensation on the liquid cooling plate in the above-mentioned battery compartment. All of the above-mentioned dehumidification equipment are arranged in the above-mentioned battery compartment.

[0047] Specifically, the liquid supply temperature judgment value is determined based on the above-mentioned first temperature difference value, the above-mentioned liquid supply temperature change rate, the liquid supply temperature difference coefficient and the liquid supply temperature change rate coefficient, so that the condensation generation situation of the liquid cooling plate is comprehensively determined based on the cooling capacity of the liquid cooling unit and the heating value of the battery.

[0048] When the liquid supply temperature determination value is less than or equal to the determination threshold value (i.e., 0), it is determined that no condensation is generated on the liquid cooling plate in the battery compartment of the liquid cooling unit;

[0049] When the liquid supply temperature determination value is greater than the determination threshold, at least part of all the dehumidification devices are controlled to start the dehumidification operation.

[0050] Specifically, when the liquid supply temperature judgment value is greater than 0, it is determined that condensation is generated on the liquid cooling plate, and an adsorption dehumidification device needs to be used to absorb the condensation generated on the liquid cooling plate to achieve the purpose of dehumidification.

[0051] In one embodiment of the present application, controlling at least part of all dehumidification devices to start dehumidification work includes:

[0052] Obtain the air dew point temperature at the current moment to obtain the second dew point temperature;

[0053] According to the magnitude of the second dew point temperature, different numbers of the dehumidification devices are controlled to start dehumidification work, wherein the controlled number is less than the total number of the dehumidification devices.

[0054] Specifically, by controlling different numbers of the above-mentioned dehumidification devices to start dehumidification work according to the size of the second dew point temperature, different degrees of dehumidification work are achieved according to the amount of condensed water, thereby improving the dehumidification efficiency.

[0055] For example, if five adsorption dehumidifiers are set up, a maximum of four can be turned on, with one left as a spare to ensure that the spare can continue to be put into use after the dehumidifier in use is saturated:

[0056] When the final liquid supply set temperature is less than or equal to the difference between the second dew point temperature and the first preset temperature, a first number (i.e., 4) of the dehumidification devices are controlled to start dehumidification, and the first number is less than the total number of the dehumidification devices;

[0057] When the final liquid supply setting temperature is greater than the difference between the second dew point temperature and the first preset temperature, and the final liquid supply setting temperature is less than or equal to the difference between the second dew point temperature and the second preset temperature, a second number (i.e., 3) of the dehumidification devices are controlled to start dehumidification, the second preset temperature is less than the first preset temperature, and the second number is less than the first number;

[0058] When the final liquid supply setting temperature is greater than the difference between the second dew point temperature and the second preset temperature, and the final liquid supply setting temperature is less than or equal to the difference between the second dew point temperature and the first preset temperature, a third number (i.e., 2) of the dehumidification devices are controlled to start dehumidification work, and the third number is less than the second number;

[0059] When the final liquid supply set temperature is greater than the difference between the second dew point temperature and the first preset temperature, a fourth number of the dehumidification devices are controlled to start dehumidification work, or all of the dehumidification devices are controlled to stop dehumidification work, and the fourth number is less than the third number.

[0060] By dynamically adjusting the number of adsorption dehumidification devices that are turned on at different humidity levels, the dehumidification effect can be guaranteed while avoiding the problem of shortened lifespan of the adsorption dehumidification devices due to long-term use.

[0061] In one embodiment of the present application, after controlling at least part of all the dehumidification devices to start dehumidification work, the method further includes:

[0062] When receiving the saturation instruction sent by the above-mentioned dehumidification equipment, the corresponding electric heating plate of the above-mentioned dehumidification equipment is controlled to turn on to dry the desiccant of the above-mentioned dehumidification equipment.

[0063] The adsorption dehumidifier will gradually become saturated in the process of absorbing moisture in the cabin. When saturation is reached, a disconnected dry contact signal will be sent to the centralized control platform, which will control the electric heater of the corresponding dehumidifier to turn on. The desiccant in the dehumidifier can be put into use again after being heated and dried. When some adsorption dehumidifiers are drying and stop working, the spare absorption dehumidifiers are put into use to ensure that there are enough absorption dehumidifiers in the system to meet the needs.

[0064] The principle of the anti-condensation control system of the energy storage cabinet is as follows Figure 2 As shown, no further details will be given here.

The abnormal high temperature of the liquid supply represents the temperature limit for preventing abnormal liquid supply of the liquid cooling unit.

[0068] Determine a temperature sum value and a temperature difference value, wherein the temperature sum value is the sum of the first dew point temperature and the first preset temperature, and the temperature difference value is the difference between the abnormal high temperature of the liquid supply and the second preset temperature;

[0069] Determine the final liquid supply set temperature as the minimum value among the initial liquid supply set temperature, the temperature sum value and the temperature difference value;

[0070] When the final liquid supply set temperature is determined to be the temperature and value, the liquid cooling unit is controlled to operate for a first preset time period at the final liquid supply set temperature;

[0073] Determine the liquid supply temperature judgment value as the sum of the first product and the second product;

[0074] When the liquid supply temperature determination value is less than or equal to the determination threshold, it is determined that no condensation is generated on the liquid cooling plate in the battery compartment of the liquid cooling unit;

[0075] When the liquid supply temperature determination value is greater than the determination threshold, the air dew point temperature at the current moment is obtained to obtain a second dew point temperature, and all dehumidification devices are arranged in the battery compartment;

[0076] When the final liquid supply set temperature is less than or equal to the difference between the second dew point temperature and the first preset temperature, a first number of dehumidification devices are controlled to start dehumidification, the first number is less than the total number of dehumidification devices, and the controlled number is less than the total number of dehumidification devices;

[0079] When the final liquid supply set temperature is greater than the difference between the second dew point temperature and the first preset temperature, controlling a fourth number of dehumidification devices to start dehumidification, the fourth number being less than the third number;

[0080] After controlling at least part of all the dehumidification devices to start dehumidification work, upon receiving a saturation instruction sent by the dehumidification device, the electric heater of the corresponding dehumidification device is controlled to turn on to dry the desiccant of the dehumidification device.
