[0050] In order to improve the temperature control effect of the liquid cooling device, the embodiments of the present application provide a liquid cooling control method, an electronic device and a storage medium. Based on the average temperature of the multiple batteries in the energy storage system, one of the highest battery temperature, the lowest battery temperature and the temperature difference is selected as the target type temperature, and then the target operation mode of the liquid cooling device is determined based on the selected target type temperature, so that the battery temperature control in the energy storage system is more accurate, thereby improving the temperature control effect of the liquid cooling device. For specific solutions, please refer to the following specific description.

[0051] In the first aspect, the embodiments of the present application provide a liquid cooling control method. Specifically, referring to Figure 1 , Figure 1 is a flowchart of one embodiment of the liquid cooling control method. In Figure 1 , the liquid cooling control method can include:

[0052] 101. Obtain the average temperature of multiple batteries in an energy storage system.

[0053] In the embodiments of the present application, the energy storage system can be, for example, an energy storage container or the like. The energy storage system includes multiple battery modules, each battery module includes multiple batteries, and the energy storage function is realized by charging and discharging of the batteries. The average temperature of the multiple batteries in the energy storage system can be, for example, the average value of the temperatures of all the batteries in the energy storage system. The temperature of the battery can be, for example, the temperature of the battery cell position, and can also be the temperature of other positions in the battery, which is not limited here.

[0054] 102. Based on the average temperature, select one of the highest battery temperature, the lowest battery temperature and the temperature difference between the highest battery temperature and the lowest battery temperature in the multiple batteries as the target type temperature.

[0055] In embodiments of the present application, the battery maximum temperature may, for example, be the maximum value of the temperatures of all the batteries in the energy storage system, and the battery minimum temperature may, for example, be the minimum value of the temperatures of all the batteries in the energy storage system. The temperature difference is the difference between the battery maximum temperature and the battery minimum temperature.

[0056] In embodiments of the present application, multiple types of temperatures are provided, such as the battery maximum temperature, the battery minimum temperature, the temperature difference, and the like. Since the average temperature represents the overall situation of the temperatures of all the batteries in the energy storage system, one type of temperature can be selected as the target type of temperature from among the battery maximum temperature, the battery minimum temperature, and the temperature difference based on the size of the average temperature, so as to perform more accurate battery temperature control based on the target type of temperature.

[0057] In some embodiments of the present application, based on the average temperature, one temperature is selected from among the battery maximum temperature, the battery minimum temperature, and the temperature difference between the battery maximum temperature and the battery minimum temperature in the multiple batteries, and is used as the target type of temperature, which can include: obtaining a preset average temperature range, the preset average temperature range being a temperature interval in which a more appropriate average temperature is located, for example, the preset average temperature range can be [22℃, 25℃). If the average temperature is within the preset average temperature range, it indicates that the average temperature is already more appropriate, and thus the temperature difference can be selected as the target type of temperature, so as to perform more accurate temperature judgment according to the temperature difference. If the average temperature is greater than the maximum value of the preset average temperature range, it indicates that the average temperature is too high, and thus the battery maximum temperature can be selected as the target type of temperature, so as to further judge whether the battery needs to be cooled according to the battery maximum temperature. If the average temperature is less than the minimum value of the preset average temperature range, it indicates that the average temperature is too low, and thus the battery minimum temperature can be selected as the target type of temperature, so as to further judge whether the battery needs to be heated according to the battery minimum temperature.

[0058] 103. Determine a target operation mode of a liquid cooling device of the energy storage system based on the target type of temperature.

[0059] In embodiments of the present application, the energy storage system is also provided with a liquid cooling device, which is used to adjust the temperature of the batteries in the energy storage system, so as to ensure that the batteries in the energy storage system are in an appropriate temperature interval when working. The liquid cooling device has multiple preset operation modes, such as a refrigeration mode, a heating mode, a self-circulation mode, a standby mode, and the like. Among them, self-circulation means that the condenser, the compressor, and the heat exchanger in the liquid cooling device do not work, but the liquid cooling medium in the liquid cooling device is driven to circulate by a water pump, so as to achieve the purpose of cooling or heating the batteries. The target operation mode is one of the preset operation modes of the liquid cooling device.

[0060] 104. Control the liquid cooling device to operate in the target operation mode.

[0061] In an embodiment of the present application, by controlling the liquid cooling device to operate in a target operating mode, the temperature of all batteries in the energy storage system is regulated or not regulated, so that the batteries in the energy storage system are in a suitable temperature range during operation.

[0062] It can be seen that in the above-mentioned embodiment of the present application, based on the average temperature of multiple batteries in the energy storage system, one of the battery maximum temperature, battery minimum temperature, and temperature difference is selected, and then the target operating mode of the liquid cooling device is determined based on the selected target type temperature, so that the battery temperature control in the energy storage system is more accurate, thereby improving the temperature control effect of the liquid cooling device.

[0063] In some embodiments of the present application, after step 104, the process may further include returning to step 101 after a preset time period to implement timed control of the temperature of the batteries in the energy storage system. The preset time period may be, for example, 1 minute.

[0064] In some embodiments of the present application, Figure 2 As shown, in Figure 1 On the basis of the illustrated embodiment, when the target type temperature is a temperature difference, determining the target operating mode of the liquid cooling device of the energy storage system based on the target type temperature may include:

[0065] 201. Obtain a magnitude relationship between the temperature difference and a first preset temperature difference and a second preset temperature difference.

[0066] In an embodiment of the present application, the first preset temperature difference and the second preset temperature difference are both preset values, and the second preset temperature difference is greater than the first preset temperature difference. For example, the second preset temperature difference may be 5° C., and the first preset temperature difference may be 2° C. The magnitude relationship between the temperature difference and the first preset temperature difference and the second preset temperature difference may be such that the temperature difference is greater than the second preset temperature difference, such that the temperature difference is greater than the first preset temperature difference and less than or equal to the second preset temperature difference, or such that the temperature difference is less than or equal to the first preset temperature difference.

[0067] 202. Based on the size relationship, select a preset operating mode from multiple preset operating modes of the liquid cooling device and use it as the target operating mode.

[0068] In an embodiment of the present application, the liquid cooling device has multiple preset operating modes, such as cooling mode, heating mode, self-circulation mode, standby mode, etc. Therefore, according to the pre-set selection rules, a preset operating mode can be selected from the multiple preset operating modes of the liquid cooling device and used as the target operating mode.

[0069] In some embodiments of the present application, based on the magnitude relationship between the temperature difference and the first preset temperature difference and the second preset temperature difference, a preset operating mode is selected from multiple preset operating modes of the liquid cooling device and used as the target operating mode. This may include: if the magnitude relationship is that the temperature difference is greater than the second preset temperature difference, it indicates that the temperature difference is too large, and therefore the cooling mode can be selected as the target operating mode to reduce the temperature difference. In addition, since the cooling mode of the liquid cooling device can be further divided into a first cooling mode and a second cooling mode, the cooling capacity of the second cooling mode is greater than the cooling capacity of the first cooling mode, that is, the cooling effect of the second cooling mode is better than the cooling effect of the first cooling mode, therefore, when the magnitude relationship is that the temperature difference is greater than the second preset temperature difference, the cooling mode selected as the target operating mode can specifically be the first cooling mode to prevent the temperature of the battery in the energy storage system from dropping too quickly and too much.

[0070] In some embodiments of the present application, based on the size relationship between the temperature difference and the first preset temperature difference and the second preset temperature difference, a preset operating mode is selected from multiple preset operating modes of the liquid cooling device and used as the target operating mode. It can include: if the size relationship is that the temperature difference is greater than the first preset temperature difference and less than or equal to the second preset temperature difference, it indicates that the temperature difference is too large, so the self-circulation mode can be selected as the target operating mode to avoid excessive temperature drop of the battery in the energy storage system while trying to reduce the temperature difference.

[0071] In some embodiments of the present application, based on the size relationship between the temperature difference and the first preset temperature difference and the second preset temperature difference, a preset operating mode is selected from multiple preset operating modes of the liquid cooling device and used as the target operating mode, which may include: if the size relationship is that the temperature difference is less than or equal to the first preset temperature difference, it indicates that the temperature difference is small and there is no need to adjust the temperature of the battery in the energy storage system, so the standby mode can be selected as the target operating mode.

[0072] It can be seen that in the above embodiments of the present application, based on the size relationship between the temperature difference and the first preset temperature difference and the second preset temperature difference, the corresponding preset operating mode is selected as the target operating mode from the multiple preset operating modes of the liquid cooling device, so that the battery temperature control is more accurate when the target type temperature is the temperature difference.

[0073] In some embodiments of the present application, Figure 3 As shown, in Figure 1 or Figure 2 Based on the illustrated embodiment, when the target type temperature is the maximum temperature of the battery, determining the target operating mode of the liquid cooling device of the energy storage system based on the target type temperature may include:

[0074] 301. If the maximum battery temperature is less than a first temperature threshold and greater than a maximum value of a preset average temperature range, determine that the target operating mode is a self-circulation mode.

[0075] In an embodiment of the present application, the first temperature threshold is a preset value and is greater than the maximum value of a preset average temperature range. For example, the first temperature threshold may be 27°C, and the preset average temperature range may be [22°C, 25°C]. If the maximum battery temperature is less than the first temperature threshold and greater than the maximum value of the preset average temperature range, indicating that the maximum battery temperature is high, the target operating mode may be determined to be the self-circulation mode. This self-circulation mode is used to equalize the temperature differences between different batteries in the energy storage system, thereby reducing the maximum battery temperature.

[0076] 302. If the maximum battery temperature is greater than or equal to a first temperature threshold, determine that the target operating mode is a cooling mode.

[0077] In an embodiment of the present application, if the maximum battery temperature is greater than or equal to the first temperature threshold, it indicates that the maximum battery temperature is too high. Therefore, the target operating mode can be determined to be the cooling mode to use the cooling mode to quickly and effectively reduce the maximum battery temperature.

[0078] In some embodiments of the present application, since the cooling mode of the liquid cooling device can be further divided into a first cooling mode and a second cooling mode, if the maximum temperature of the battery is less than the first temperature threshold and greater than the maximum value of the preset average temperature range, determining that the target operating mode is the self-circulation mode may include: if the maximum temperature of the battery is greater than or equal to the first temperature threshold and less than the second temperature threshold, it indicates that the maximum temperature of the battery is less excessive, so the target operating mode can be determined to be the first cooling mode. Wherein, the second temperature threshold is greater than the first temperature threshold, for example, the second temperature threshold can be 33°C, and the first temperature threshold can be 27°C. If the maximum temperature of the battery is greater than or equal to the second temperature threshold, it indicates that the maximum temperature of the battery is more excessive, so the target operating mode can be determined to be the second cooling mode, so as to reduce the maximum temperature of the battery as quickly as possible, so that the temperature of the battery in the energy storage system is restored to the appropriate temperature range as soon as possible.

[0079] In some embodiments of the present application, Figure 4 As shown, in Figures 1 to 3 Based on any of the embodiments shown, when the target type temperature is the lowest temperature of the battery, determining the target operating mode of the liquid cooling device of the energy storage system based on the target type temperature may include:

[0080] 401. If the lowest battery temperature is greater than or equal to a third temperature threshold, determine that the target operating mode is the self-circulation mode.

[0081] In an embodiment of the present application, the third temperature threshold is a preset value and is less than the minimum value of a preset average temperature range. For example, the third temperature threshold may be 16°C, and the preset average temperature range may be [22°C, 25°C]. If the minimum battery temperature is greater than or equal to the third temperature threshold, it indicates that the minimum battery temperature is low. Therefore, the target operating mode may be determined to be the self-circulation mode. This self-circulation mode is used to equalize the temperature differences between different batteries in the energy storage system, thereby raising the minimum battery temperature.

[0082] 402. If the lowest battery temperature is less than a third temperature threshold, determine that the target operating mode is a heating mode.

[0083] In an embodiment of the present application, if the battery minimum temperature is less than the third temperature threshold, it indicates that the battery minimum temperature is too low. Therefore, the target operating mode can be determined to be the heating mode to use the heating mode to quickly and effectively increase the battery minimum temperature.

[0084] In some embodiments of the present application, when the target operating mode is determined to be the heating mode, controlling the liquid cooling device to operate in the target operating mode may include: controlling the liquid cooling device to operate in the heating mode until a preset condition is satisfied, and then returning to step 101. The preset condition includes at least one of a maximum battery temperature being greater than or equal to a second temperature threshold, and a minimum battery temperature being greater than or equal to a fourth temperature threshold, wherein the fourth temperature threshold is greater than the third temperature threshold and less than the minimum value of a preset average temperature range. For example, the fourth temperature threshold may be 20°C, the third temperature threshold may be 16°C, and the preset average temperature range may be [22°C, 25°C]. It is understood that when the maximum battery temperature is greater than or equal to the second temperature threshold (e.g., 33°C), it indicates that any further increase in the maximum battery temperature would be too high. Therefore, it is determined that the preset condition is satisfied, and the step of controlling the liquid cooling device to operate in the heating mode is stopped, and the process returns to step 101 to redetermine the target operating mode. When the minimum battery temperature is greater than or equal to the fourth temperature threshold (for example, 20°C), it indicates that any further increase in the minimum battery temperature will be too high. Therefore, it can be determined that the preset conditions are met, and the step of controlling the liquid cooling device to operate in the heating mode is stopped, and the process returns to step 101 to redetermine the target operating mode.

[0085] In a second aspect, based on the liquid cooling control method of the above embodiment, an embodiment of the present application provides a liquid cooling control device, which is used to perform the steps of any of the embodiments of the above liquid cooling control method. For example, the liquid cooling control device can be a BMS (Battery Management System) device, and the liquid cooling device is completely controlled by the BMS device to avoid conflicts caused by other control devices controlling the liquid cooling device. Specifically, the liquid cooling control device may include:

[0089] The control module is used to control the liquid cooling device to operate in a target operation mode.
