[0007] obtaining a switching state of an operating mode of an energy storage valve in an energy storage valve system;

[0008] adjusting a working mode of an internal cooling device in the energy storage valve cooling system according to the switching state.

[0009] In the technical solution of the present application, the working mode of the internal cooling device in the energy storage valve cooling system is adaptively adjusted according to the switching state of the operating mode of the energy storage valve, so that the cooling flow of the internal cooling device in the energy storage valve cooling system can adapt to the heat generated by the energy storage valve during operation, thereby saving the power consumption of the energy storage valve cooling system and improving the operation efficiency of the energy storage valve cooling system and the energy storage valve system.

[0010] In some embodiments, adjusting the working mode of the internal cooling device in the energy storage valve cooling system according to the switching state comprises:

[0059] The embodiments of the technical solutions of the present application will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present application; the terms "comprise" and any variations thereof in the specification and claims of the present application and the above description of drawings are intended to cover non-exclusive inclusion.

[0061] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "a plurality of" is two or more (including two), unless otherwise explicitly specified.

[0062] The control method, device, equipment and storage medium provided by the embodiments of the present application can be applied to the control application scenario of the high-voltage direct-hanging energy storage valve cooling system; of course, it can also be applied to other application scenarios.

[0063] Generally, a high-voltage direct-hanging energy storage valve can include a plurality of energy storage parts, wherein each energy storage part can include but is not limited to a power module and a battery module. During the operation of the high-voltage direct-hanging energy storage valve, each power module and each battery module will generate heat, and therefore, an energy storage valve cooling system needs to be designed to take away the generated heat.

[0064] The traditional low-voltage energy storage converter (Power Conversion System, PCS) is air-cooled, and the battery module is liquid-cooled, and the two do not share a cooling system. When the battery module is not running, the cooling system corresponding to the battery module can stop running. In the related art, considering the compactness of the structure design, each power module and each battery module in the high-voltage direct-hanging energy storage valve can share an energy storage valve cooling system. In the case that the high-voltage direct-hanging energy storage valve is in a zero-power operation mode, the battery module can not be cooled, but considering that the power module generates a high amount of heat during operation, if it is not cooled, the junction temperature of the power module is high when it starts to operate, which can easily damage the device, and therefore, the power module needs to be cooled.

[0065] However, since the cooling flow of the energy storage valve cooling system is large, the energy storage valve cooling system runs at a constant flow for 24 hours, which can cause the energy storage valve cooling system to consume a large amount of power, thereby reducing the operation efficiency of the high-voltage direct connection energy storage system.

[0066] To solve the problem of large power consumption of the energy storage valve cooling system in the related art, embodiments of the present application propose to adjust the working mode of the internal cooling device in the energy storage valve cooling system according to different operation modes of the energy storage valve in the energy storage valve system, so that the cooling flow of the energy storage valve cooling system can adapt to the heat generated by the energy storage valve during operation, thereby saving the power consumption of the energy storage valve cooling system and improving the operation efficiency of the energy storage valve cooling system and the energy storage valve system.

[0067] Figure 1 The schematic diagram of the application environment provided by the embodiments of the present application is shown in Figure 1 As shown, the application environment of the embodiments of the present application can include but is not limited to an energy storage valve system 10, a first control device 11 of the energy storage valve system, an energy storage valve cooling system 12, and a second control device 13 of the energy storage valve cooling system. It should be understood that the first control device 11 can control the devices in the energy storage valve system 10, the second control device 13 can control the devices in the energy storage valve cooling system 12, and the first control device 11 and the second control device 13 can communicate with each other.

[0068] For example, the energy storage valve system 10 in the embodiments of the present application can include but is not limited to a plurality of energy storage valves; the energy storage valve cooling system 12 can include but is not limited to an internal cooling device, wherein the internal cooling device can be used to power the circulation of the cooling medium, so that the cooling medium can take away the heat generated by the operation of the energy storage valve in the energy storage valve system 10.

[0069] For example, the internal cooling device in the embodiments of the present application can include but is not limited to an internal cooling main pump, or other types of devices that can provide power.

[0070] It should be noted that the first control device 11 can adopt the control method of the energy storage valve cooling system provided by the embodiments of the present application.

[0071] It should be understood that the first control device 11 and the second control device 13 in the embodiments of the present application can be integrated into one control device.

[0072] For ease of understanding, the energy storage valve cooling system and some terms in the embodiments of the present application are described first.

[0073] Figure 2 The structural schematic diagram of the energy storage valve cooling system passed by the embodiments of the present application is shown in Figure 2As shown, the energy storage valve cooling system provided by the embodiment of the present application can include, but is not limited to, an internal cooling device 20, an external cooling heat exchange module 21, a deionization module 22, and an operating parameter monitoring module 23.

[0074] The internal cooling device can be used to provide power for circulation of the cooling medium, so that the cooling medium can take away the heat generated by the operation of the energy storage valve in the energy storage valve system.

[0075] The external cooling heat exchange module 21 can be used to cool the cooling medium with increased temperature and release the heat to the external environment. Exemplarily, the external cooling heat exchange module 21 can include, but is not limited to, a refrigeration unit.

[0076] The deionization module 22 can be used to reduce the conductivity of the cooling medium to ensure that the conductivity of the cooling medium meets the operation requirements. Exemplarily, the deionization module 22 can include, but is not limited to, a deionization resin tank and a conductivity instrument.

[0077] The operating parameter monitoring module 23 can be used to monitor the temperature and flow of the cooling medium in the energy storage valve cooling system. Figure 3 The structure diagram of the operating parameter monitoring module provided by the embodiment of the present application is shown in Figure 3 As shown, the operating parameter monitoring module 23 can include, but is not limited to, a temperature monitoring instrument 230 and a flow monitoring instrument 231.

[0078] Figure 4 The structure diagram of the internal cooling device provided by the embodiment of the present application is shown in Figure 4 As shown, the internal cooling device 20 provided by the embodiment of the present application can include, but is not limited to, a frequency converter 200 and a motor rotating part 201, wherein the frequency converter 200 can receive the control instruction issued by the first control device 11 and adjust the rotating speed of the motor rotating part 201 according to the control instruction, so that the internal cooling device is in different working modes.

[0079] It should be noted that the structure of the energy storage valve cooling system provided by the above embodiment of the present application is illustrative, and other structures of the cooling system can also be used, as long as the cooling system includes an internal cooling device, the control method of the energy storage valve cooling system provided by the embodiment of the present application can be used.

[0080] The operation mode of the energy storage valve involved in the embodiments of the present application can include but is not limited to any one of the following: peak clipping operation mode, frequency regulation operation mode, zero power operation mode. Among them, the peak clipping operation mode can mean that the battery module in the energy storage valve is in the charging and discharging state; the frequency regulation operation mode can mean the regulation of supporting the frequency of the power grid; the zero power operation mode can mean that the power module and the battery module in the energy storage valve are in a non-operation state. It should be noted that the heat generated by the energy storage valve in the peak clipping operation mode or the frequency regulation operation mode will be greater than the heat generated by the energy storage valve in the zero power operation mode.

[0081] The working mode of the internal cooling device involved in the embodiments of the present application can include but is not limited to a rated working mode or a low-frequency working mode. Among them, the rated working frequency of the internal cooling device in the rated working mode is greater than the low-frequency working frequency in the low-frequency working mode. For example, the rated working frequency can be 50 Hz, and the low-frequency working frequency can be 25 Hz or other frequencies less than 50 Hz.

[0082] In the embodiments of the present application, when the working mode of the internal cooling device is the rated working mode, the flow of the cooling medium of the internal cooling device can meet the cooling medium flow required by the energy storage valve in the peak clipping operation mode or the frequency regulation operation mode.

[0083] In the embodiments of the present application, when the working mode of the internal cooling device is the low-frequency working mode, the flow of the cooling medium of the internal cooling device can meet the cooling medium flow required by the energy storage valve when switching from the zero power operation mode to the peak clipping operation mode or the frequency regulation operation mode, so as to avoid the case that the devices in the power module and the battery module overheat during the switching process, resulting in device loss or thermal runaway of the battery module.

[0084] In some embodiments, Figure 5 The flowchart of the control method of the energy storage valve cooling system provided in some embodiments of the present application is described by taking the first control device of the energy storage valve system in Figure 1 as an example. As shown in Figure 5 , the method of the embodiments of the present application can include the following steps:

[0085] Step S501, obtaining the switching state of the operation mode of the energy storage valve in the energy storage valve system.

[0086] The energy storage valve system in the embodiments of the present application can include a plurality of energy storage valves, and any energy storage valve can include but is not limited to a power module and a battery module. Considering the compactness design, each power module and each battery module in the embodiments of the present application can share the refrigeration of the energy storage valve cooling system to take away the heat generated by the energy storage valve in the energy storage valve system during operation.

[0087] The switching state of the operation mode of the energy storage valve in the embodiment of the present application can be used to indicate the second operation mode of the energy storage valve after switching, and of course can also be used to indicate other information, such as the first operation mode of the energy storage valve before switching, and the like.

[0088] It should be understood that the operation modes of the plurality of energy storage valves in the energy storage valve system can be the same. For example, in the case that the operation mode of any energy storage valve in the energy storage valve system is switched from the first operation mode to the second operation mode, the operation modes of the other energy storage valves in the energy storage valve system are also switched from the first operation mode to the second operation mode.

[0089] In this step, the first control device can acquire the switching state of the operation mode of the energy storage valve in the energy storage valve system in real time, the first control device can acquire the switching state of the operation mode of the energy storage valve in the energy storage valve system every preset time interval, or the first control device can acquire the switching state of the operation mode of the energy storage valve in the energy storage valve system in the case of receiving an adjustment instruction.

[0090] In a possible implementation manner, the first control device can determine the switching state according to detection information of the energy storage valve operation mode detection device, wherein the detection information can include but is not limited to the operating voltage and / or operating current of the energy storage valve. It should be understood that the energy storage valve operation mode detection device can include but is not limited to a voltage detection device and a current detection device arranged in the energy storage valve system, wherein the voltage detection device is used to detect the operating voltage of the energy storage valve in the energy storage valve system, and the current detection device is used to detect the operating current of the energy storage valve in the energy storage valve system. It should be noted that the energy storage valve operation mode detection device can communicate with the first control device so as to send the detection information to the first control device.

[0091] In another possible implementation manner, the first control device can receive the switching state of the operation mode of the energy storage valve in the energy storage valve system sent by other devices.

[0092] Of course, the first control device can also acquire the switching state of the operation mode of the energy storage valve in the energy storage valve system through other manners.

[0093] In step S502, the working mode of the internal cooling device in the energy storage valve cooling system is adjusted according to the switching state.

[0094] In this step, according to the switching state of the operation mode of the energy storage valve in the energy storage valve system, the first control device can adaptively adjust the working mode of the internal cooling device in the energy storage valve cooling system according to a preset adjustment strategy, so that the cooling flow of the working mode of the internal cooling device after adjustment can adapt to the heat generated by the energy storage valve in the operation process; wherein the preset adjustment strategy is used to indicate the working mode (or called target working mode) of the internal cooling device after adjustment corresponding to different switching states.

[0095] The control method of the energy storage valve cooling system can obtain the switching state of the operating mode of the energy storage valve in the energy storage valve system, and adjust the working mode of the internal cooling device in the energy storage valve cooling system according to the switching state. As can be seen, in the embodiments of the present application, the working mode of the internal cooling device in the energy storage valve cooling system is adaptively adjusted according to the switching state of the operating mode of the energy storage valve, so that the cooling flow of the internal cooling device in the energy storage valve cooling system can adapt to the heat generated by the energy storage valve during operation, thereby saving the power consumption of the energy storage valve cooling system and improving the operating efficiency of the energy storage valve cooling system and the energy storage valve system.

[0096] In some embodiments, Figure 6 The flowchart of the working mode adjustment method of the internal cooling device in the energy storage valve cooling system provided by some embodiments of the present application is shown in the above embodiment. The related content of the step S502 of adjusting the working mode of the internal cooling device in the energy storage valve cooling system according to the switching state is described in the embodiments of the present application. As shown in Figure 6 The step S502 of the above embodiment of the present application can include the following steps:

[0097] In step S5021, the target working mode of the internal cooling device is determined according to the switching state.

[0098] In this step, the first control device can determine the target working mode of the internal cooling device in the energy storage valve cooling system that matches the operating mode of the energy storage valve according to the switching state of the operating mode of the energy storage valve in the energy storage valve system, wherein the cooling flow of the internal cooling device in the energy storage valve cooling system in the target working mode can meet the operating cooling demand of the power module and the battery module in the energy storage valve system, so that the cooling flow of the internal cooling device in the energy storage valve cooling system can adapt to the heat generated by the energy storage valve during operation.

[0099] Optionally, the first control device can determine the first operating mode before the switching of the energy storage valve and the second operating mode after the switching according to the switching state, and determine the target working mode according to the heat generated by the energy storage valve in the first operating mode and the heat generated by the energy storage valve in the second operating mode.

[0100] In the embodiments of the present application, the first control device can determine the first operating mode before the switching of the energy storage valve and the second operating mode after the switching according to the switching state of the operating mode of the energy storage valve in the energy storage valve system, wherein the heat generated by the energy storage valve in the first operating mode and the second operating mode can be the same, or the heat generated by the energy storage valve in the first operating mode and the second operating mode can be different.

[0101] Further, the first control device can determine the target working mode according to the heat generated by the energy storage valve in the first operating mode and the heat generated by the energy storage valve in the second operating mode.

[0102] It should be noted that, in the case that the heat generation of the energy storage valve in the first operation mode is different from the heat generation of the energy storage valve in the second operation mode, the first control device needs to adjust the operation mode of the internal cooling device in the energy storage valve cooling system, that is, the target operation mode is different from the current operation mode; in the case that the heat generation of the energy storage valve in the first operation mode is the same as the heat generation of the energy storage valve in the second operation mode, the first control device does not need to adjust the operation mode of the internal cooling device in the energy storage valve cooling system, that is, the target operation mode is the same as the current operation mode.

[0103] In the following embodiments of the present application, the related content of how to determine the target operation mode in the case that the heat generation of the energy storage valve in the first operation mode is different from the heat generation of the energy storage valve in the second operation mode is mainly described.

[0104] Exemplarily, the first operation mode in the embodiments of the present application can be a peak clipping and valley filling operation mode or a frequency modulation operation mode, and the second operation mode can be a zero power operation mode.

[0105] Exemplarily, the first operation mode in the embodiments of the present application can be a zero power operation mode, and the second operation mode can be a peak clipping and valley filling operation mode or a frequency modulation operation mode.

[0106] In a possible implementation, if the heat generation of the energy storage valve in the first operation mode is less than the heat generation of the energy storage valve in the second operation mode, the rated operation mode of the internal cooling device is taken as the target operation mode, wherein the working frequency of the internal cooling device in the rated operation mode is a rated working frequency.

[0107] In the implementation, if the heat generation of the energy storage valve in the first operation mode is less than the heat generation of the energy storage valve in the second operation mode, that is, the energy storage valve is switched from the first operation mode with less heat generation to the second operation mode with more heat generation, that is, more cooling medium flow is needed, the first control device can take the rated operation mode of the internal cooling device as the target operation mode, so that the cooling medium flow of the internal cooling device can meet the cooling medium flow required by the energy storage valve in the second operation mode.

[0108] For example, assuming that the first operation mode is a zero power operation mode, and the second operation mode is a peak clipping and valley filling operation mode or a frequency modulation operation mode, the first control device can take the rated operation mode of the internal cooling device as the target operation mode in the case that the operation mode of the energy storage valve in the energy storage valve system is switched from the zero power operation mode to the peak clipping and valley filling operation mode or the frequency modulation operation mode, so that the cooling medium flow of the internal cooling device can meet the cooling medium flow required by the energy storage valve in the peak clipping and valley filling operation mode or the frequency modulation operation mode.

[0109] In another possible implementation, if the heat generation of the energy storage valve in the first operation mode is greater than the heat generation in the second operation mode, the low-frequency operation mode of the internal cooling device is taken as the target operation mode, where the working frequency of the internal cooling device in the low-frequency operation mode is a low-frequency working frequency, and the low-frequency working frequency is less than the rated working frequency of the internal cooling device.

[0110] In this implementation, if the heat generation of the energy storage valve in the first operation mode is greater than the heat generation in the second operation mode, that is, the energy storage valve is switched from the first operation mode with more heat generation to the second operation mode with less heat generation, that is, less cooling medium flow is required, the first control device can take the low-frequency operation mode of the internal cooling device as the target operation mode, so that the cooling medium flow of the internal cooling device can meet the cooling medium flow required when the energy storage valve is switched from the second operation mode to the first operation mode, so as to avoid the case that the devices in the power module and the battery module overheat during the switching process, causing device loss or thermal runaway of the battery module.

[0111] For example, assuming that the first operation mode is a peak clipping or frequency modulation operation mode, and the second operation mode is a zero-power operation mode, the first control device can take the low-frequency operation mode of the internal cooling device as the target operation mode when detecting that the operation mode of the energy storage valve in the energy storage valve system is switched from the peak clipping or frequency modulation operation mode to the zero-power operation mode, so that the cooling medium flow of the internal cooling device can meet the cooling medium flow required when the energy storage valve is switched from the zero-power operation mode to the peak clipping or frequency modulation operation mode.

[0112] It can be seen that in this implementation, in the case where the energy storage valve is switched from the first operation mode with more heat generation to the second operation mode with less heat generation, by taking the low-frequency operation mode of the internal cooling device as the target operation mode, the battery module and the power module can be reliably operated for a long time on the basis of reducing the power consumption of the energy storage valve cooling system.

[0113] Step S5022, switching the current operation mode of the internal cooling device to the target operation mode.

[0114] In this step, the first control device can switch the current operation mode of the internal cooling device in the energy storage valve cooling system to the target operation mode matched with the operation mode of the energy storage valve in the energy storage valve system. It can be seen that in the embodiments of the present application, by switching the current operation mode of the internal cooling device to the target operation mode matched with the operation mode of the energy storage valve according to the different operation modes of the energy storage valve in the energy storage valve system, the cooling flow of the energy storage valve cooling system can be adapted to the heat generated by the energy storage valve during operation, so as to save the power consumption of the energy storage valve cooling system and improve the operation efficiency of the energy storage valve cooling system and the energy storage valve system.

[0115] Exemplarily, the first control device can send a control instruction to the second control device of the energy storage valve cooling system, where the control instruction can be used to instruct to switch the current working mode of the internal cooling device to the target working mode, so that the second control device can switch the current working mode of the internal cooling device to the target working mode according to the control instruction, thereby realizing the working mode switching of the internal cooling device. The control instruction can include, but is not limited to, identification information of the target working mode, or a working frequency corresponding to the target working mode.

[0116] It should be noted that if the first control device of the energy storage valve system and the second control device of the energy storage valve cooling system in the embodiment of the present application can be integrated into one control device, the control device can directly control the current working mode of the internal cooling device to be switched to the target working mode.

[0117] In a possible implementation, in a case where the target working mode of the internal cooling device is determined to be the rated working mode according to the switching state, the first control device can timely switch the current working mode of the internal cooling device to the target working mode, so that the cooling flow of the energy storage valve cooling system can quickly adapt to the heat generated by the energy storage valve in the running process.

[0118] In another possible implementation, in a case where the target working mode of the internal cooling device is determined to be the low-frequency working mode according to the switching state, the first control device can delay for a target time duration and then switch the current working mode of the internal cooling device to the target working mode.

[0119] In the implementation, in a case where the target working mode of the internal cooling device is determined to be the low-frequency working mode according to the switching state, considering that the internal cooling device needs a response time to switch from the low-frequency working mode to the rated working mode when the energy storage valve is switched from the second running mode to the first running mode with more heat generation, in order to prevent the cooling medium flow of the internal cooling device from being unable to meet the cooling demand of the energy storage valve in the process of switching to the first running mode when the internal cooling device is subsequently switched to the rated working mode, the first control device can delay for a target time duration and then switch the current working mode of the internal cooling device to the target working mode, so that the operating temperature of the power module and the battery module in the energy storage valve in the energy storage valve system can be reduced by a certain temperature, thereby avoiding the case that the devices in the power module and the battery module are over-temperature in the process of switching from the second running mode to the first running mode, resulting in device loss or thermal runaway of the battery module.

[0120] Exemplarily, the first control device can start a timer according to the determination of the target working mode of the internal cooling device, and switch the current working mode of the internal cooling device to the target working mode when the timer reaches the target time duration.

[0121] Of course, the first control device can also switch the current working mode of the internal cooling device to the target working mode after the delay target time length in other manners.

[0122] To sum up, in the embodiment of the present application, the target working mode of the internal cooling device is determined according to the switching state of the operating mode of the energy storage valve in the energy storage valve system, and the current working mode of the internal cooling device is further switched to the target working mode. It can be seen that, in the embodiment of the present application, the current working mode of the internal cooling device is adjusted to the target working mode matched with the operating mode of the energy storage valve according to the switching state of the operating mode of the energy storage valve in the energy storage valve system, so that the cooling flow of the internal cooling device in the energy storage valve cooling system can be more suitable for the heat generated by the energy storage valve in the running process, thereby the power consumption of the energy storage valve cooling system can be further saved, and the operating efficiency of the energy storage valve cooling system and the energy storage valve system can be improved.

[0123] In some embodiments, on the basis of the above-mentioned embodiments, the present embodiment further describes the content related to the step S5022 of "switching the current working mode of the internal cooling device to the target working mode".

[0124] For example, the internal cooling device of the embodiment of the present application can include but is not limited to a frequency converter and a motor rotating part, and the first control device can control the frequency converter in the internal cooling device according to the working frequency corresponding to the target working mode of the internal cooling device, so as to adjust the rotating speed of the motor rotating part in the internal cooling device, thereby realizing the switching of the current working mode of the internal cooling device to the target working mode. It should be understood that the working frequency of the frequency converter can be the same as the working frequency corresponding to the target working mode.

[0125] In a possible implementation manner, the first control device can send an adjustment instruction to the frequency converter in the internal cooling device, so that the frequency converter can adjust the working frequency according to the adjustment instruction, so as to adjust the rotating speed of the motor rotating part in the internal cooling device, wherein the adjustment instruction can include but is not limited to the identification information of the target working mode or the working frequency corresponding to the target working mode.

[0126] In another possible implementation manner, the first control device can send a control instruction to the second control device of the energy storage valve cooling system, so that the second control device sends an adjustment instruction to the frequency converter in the internal cooling device according to the control instruction, so that the frequency converter can adjust the working frequency according to the adjustment instruction, so as to adjust the rotating speed of the motor rotating part in the internal cooling device.

[0127] Of course, the first control device can also control the frequency converter in the internal cooling device according to the working frequency corresponding to the target working mode of the internal cooling device in other manners.

[0128] For the convenience of understanding, the following embodiments of the present application explain the case that the target working mode is different working modes.

[0129] In a possible implementation, if the target working mode is the rated working mode, the first control device can control the working frequency of the frequency converter in the internal cooling device according to the rated working frequency corresponding to the rated working mode, so as to adjust the rotating speed of the motor rotating part, thereby controlling the internal cooling device to operate in the rated working mode.

[0130] The following embodiments of the present application explain the determination process of the internal cooling device in the rated working mode corresponding to the rated working frequency and the cooling medium flow.

[0131] In order to ensure that the battery module and the power module of the energy storage valve in the energy storage valve system operate normally in the peak load shifting operation mode or the frequency modulation operation mode, it is assumed that the cooling medium flow required for cooling a single battery module is QE, the cooling medium flow required for cooling a single power module is QI, the monitored inlet temperature of the cooling medium is T1, the maximum allowable temperature of the steady-state operation of a single battery module is TE, the maximum allowable temperature of the steady-state operation of a single power module is TI, the operating heat generation power of a single battery module is PE, and the operating heat generation power of a single power module is PI.

[0132] According to TE=T1+KE*QE*PE, QE=(TE-T1) / (KE*PE) can be obtained.

[0133] Wherein, KE is a first preset equivalent calculation coefficient, which is affected by the water-cooled plate thermal resistance in the battery module and the battery body heat transfer thermal resistance.

[0134] According to TI=T1+KI*QI*PI, QI=(TI-T1) / (KI*PI) can be obtained.

[0135] Wherein, KI is a second preset equivalent calculation coefficient, which is affected by the water-cooled plate thermal resistance in the power module and the battery body heat transfer thermal resistance.

[0136] As can be seen from the above, the cooling medium flow Q1 of the internal cooling device in the energy storage valve cooling system in the rated working mode corresponding to the rated working frequency F1 is N1*QE+N2*QI, wherein N1 represents a calculation coefficient of the number of battery modules of the energy storage valve in the energy storage valve system, and N2 represents a calculation coefficient of the number of power modules of the energy storage valve in the energy storage valve system.

[0137] It should be noted that there is a preset mapping relationship between the outlet flow (or cooling medium flow) of the internal cooling device and the corresponding working frequency. Therefore, according to the cooling medium flow required for the energy storage valve in the energy storage valve system in the peak load shifting operation mode or the frequency modulation operation mode, the rated working frequency of the corresponding internal cooling device in the rated working mode can be determined.

[0138] In another possible implementation, if the target working mode is the low-frequency working mode, the first control device can control the working frequency of the frequency converter in the internal cooling device according to the low-frequency working frequency corresponding to the low-frequency working mode, so as to adjust the rotating speed of the motor rotating part, thereby controlling the internal cooling device to operate in the low-frequency working mode.

[0139] The determination process of the internal cooling device in the low-frequency working mode corresponding to the low-frequency working frequency and the cooling medium flow is described in the following embodiments of the present application.

[0140] Due to the influence of the internal cooling device structure and system inertia, the cooling medium flow of the internal cooling device needs a response time to recover to the cooling medium flow Q1 at the rated working frequency F1 corresponding to the rated working mode when the internal cooling device is switched from the low-frequency working mode to the rated working mode, thus causing the cooling medium flow of the battery module to recover to the rated flow QE and the cooling medium flow of the power module to recover to the rated flow QI to take time, and the devices in the power module and the battery module are prone to over-temperature in this process, causing device damage and battery module thermal runaway, thus the following control needs to be performed:

[0141] Considering that the energy storage valve in the energy storage valve system is switched from the peak clipping and valley filling operation mode or the frequency modulation operation mode to the zero power operation mode, the battery module and the power module stop operating and heating, thus in the case where it is necessary to switch the working mode of the internal cooling device from the rated working mode to the low-frequency working mode, the operating temperature of the battery module can be reduced from TE to TE1 and the operating temperature of the power module can be reduced from TI to TI1 by delaying the target time length and then switching the working mode of the internal cooling device from the rated working mode to the low-frequency working mode.

[0142] The cooling medium flow Q2 of the internal cooling device in the energy storage valve cooling system at the low-frequency working frequency F2 corresponding to the low-frequency working mode is N1*QE1+N2*QI1.

[0143] The cooling medium flow QE1 required for cooling a single battery module is (TE-TE1) / (KE1*PE); the cooling medium flow QI1 required for cooling a single power module is (TI-TI1) / (KI1*PI); KE1 is a third equivalent calculation coefficient affected by the water-cooled plate thermal resistance in the battery module and the battery body heat transfer thermal resistance under flow change; and KI1 is a fourth equivalent calculation coefficient affected by the water-cooled plate thermal resistance in the power module and the battery body heat transfer thermal resistance under flow change.

[0144] It should be noted that there is a preset mapping relationship between the cooling medium flow of the internal cooling device and the corresponding working frequency. Therefore, according to the cooling medium flow required by the energy storage valve in the zero power operation mode of the energy storage valve system, the low frequency working frequency of the corresponding internal cooling device in the low frequency working mode can be determined.

[0145] To sum up, in the embodiment of the present application, the working mode of the internal cooling device is switched by the frequency converter based on the internal cooling device. The cooling flow of the energy storage valve cooling system can be adapted to the heat generated by the energy storage valve during operation, thereby saving the power consumption of the energy storage valve cooling system. Moreover, the switching mode of the internal cooling device is simple and convenient, thereby improving the switching efficiency.

[0146] For ease of understanding, in the following embodiments of the present application, the operation mode of the energy storage valve includes peak clipping and valley filling operation mode, frequency modulation operation mode or zero power operation mode, and the working mode of the internal cooling device can include rated working mode or low frequency working mode. The control method of the energy storage valve cooling system in the embodiment of the present application is further described.

[0148] 1) The first control device of the energy storage valve system can determine that the target working mode of the internal cooling device in the energy storage valve cooling system is the rated working mode when detecting that the operation mode of the energy storage valve in the energy storage valve system is the peak clipping and valley filling operation mode or the frequency modulation operation mode, and send a first control instruction to the second control device of the energy storage valve cooling system. The first control instruction can be used to instruct to switch the working mode of the internal cooling device to the rated working mode, so that the second control device can switch the working mode of the internal cooling device to the rated working mode according to the first control instruction.

[0149] 2) The first control device of the energy storage valve system can determine that the target working mode of the internal cooling device in the energy storage valve cooling system is the low frequency working mode when detecting that the operation mode of the energy storage valve in the energy storage valve system is the zero power operation mode, and send a second control instruction to the second control device of the energy storage valve cooling system. The second control instruction can be used to instruct to switch the working mode of the internal cooling device to the low frequency working mode, so that the second control device can switch the working mode of the internal cooling device to the low frequency working mode according to the second control instruction.

[0150] II. During operation

[0151] (1) Figure 7 Switching diagram of the operation mode of the energy storage valve in the energy storage valve system and the working mode of the internal cooling device in the energy storage valve cooling system provided in the embodiment of the present application Figure 1 For example, Figure 7As shown, in a case where the first control device detects that the operating mode of the energy storage valve in the energy storage valve system is switched from the peak load shifting operating mode to the zero power operating mode, the first control device can determine that the target operating mode of the internal cooling device in the energy storage valve cooling system is the low frequency operating mode, and can send a second control instruction to the second control device of the energy storage valve cooling system, where the second control instruction can be used to instruct to switch the current operating mode of the internal cooling device to the low frequency operating mode, so that the second control device can switch the operating mode of the internal cooling device from the rated operating mode to the low frequency operating mode according to the second control instruction. It should be noted that the operating mode of the internal cooling device needs to be switched to the low frequency operating mode after a target time delay.

[0152] For example, the first control device can send the second control instruction to the second control device after a target time delay in a case where the first control device determines that the target operating mode of the internal cooling device is the low frequency operating mode.

[0153] For another example, the first control device can send the second control instruction to the second control device in a case where the first control device determines that the target operating mode of the internal cooling device is the low frequency operating mode, where the second control instruction can carry a target time, so that the second control device can switch the operating mode of the internal cooling device to the low frequency operating mode according to the second control instruction after a target time delay in a case where the second control device receives the second control instruction.

[0154] Further, in a case where the first control device detects that the operating mode of the energy storage valve in the energy storage valve system is switched from the zero power operating mode to the peak load shifting operating mode, the first control device can determine that the target operating mode of the internal cooling device in the energy storage valve cooling system is the rated operating mode, and can send a first control instruction to the second control device of the energy storage valve cooling system, where the first control instruction can be used to instruct to switch the current operating mode of the internal cooling device to the rated operating mode, so that the second control device can switch the operating mode of the internal cooling device from the low frequency operating mode to the rated operating mode according to the first control instruction.

[0155] (2) Figure 8 Switching of the operating mode of the energy storage valve in the energy storage valve system and the operating mode of the internal cooling device in the energy storage valve cooling system provided by the embodiments of the present application Figure 2 For example, Figure 8As shown, when the first control device detects that the operating mode of the energy storage valve in the energy storage valve system has switched from frequency regulation operating mode to zero power operating mode, it can determine that the target operating mode of the internal cooling device in the energy storage valve cooling system is low-frequency operating mode. It can then send a second control command to the second control device of the energy storage valve cooling system. This second control command instructs the internal cooling device to switch its current operating mode to low-frequency operating mode, enabling the second control device to switch the internal cooling device's operating mode from the rated operating mode to the low-frequency operating mode according to the second control command. It should be noted that the internal cooling device's operating mode needs to switch to low-frequency operating mode after a target delay.

[0156] Furthermore, when the first control device detects that the operating mode of the energy storage valve in the energy storage valve system has switched from zero-power operating mode to frequency modulation operating mode, it can determine that the target operating mode of the internal cooling device in the energy storage valve cooling system is the rated operating mode, and can send a first control command to the second control device of the energy storage valve cooling system. The first control command can be used to instruct the current operating mode of the internal cooling device to be switched to the rated operating mode, so that the second control device can switch the operating mode of the internal cooling device from low-frequency operating mode to the rated operating mode according to the first control command.

[0157] (3) Figure 9 This application provides a schematic diagram illustrating the switching between the operating modes of the energy storage valve and the working modes of the internal cooling equipment in the energy storage valve cooling system. Figure 3 ,like Figure 9 As shown, when the first control device detects that the operating mode of the energy storage valve in the energy storage valve system has switched from peak shaving and valley filling mode to zero-power operation mode, it can determine that the target operating mode of the internal cooling device in the energy storage valve cooling system is low-frequency operation mode. It can then send a second control command to the second control device of the energy storage valve cooling system. This second control command instructs the internal cooling device to switch its current operating mode to low-frequency operation mode, enabling the second control device to switch the internal cooling device's operating mode from the rated operating mode to the low-frequency operating mode according to the second control command. It should be noted that the internal cooling device's operating mode needs to switch to low-frequency operation mode after a target delay.

[0158] Furthermore, when the first control device detects that the operating mode of the energy storage valve in the energy storage valve system has switched from zero-power operating mode to frequency modulation operating mode, it can determine that the target operating mode of the internal cooling device in the energy storage valve cooling system is the rated operating mode, and can send a first control command to the second control device of the energy storage valve cooling system. The first control command can be used to instruct the current operating mode of the internal cooling device to be switched to the rated operating mode, so that the second control device can switch the operating mode of the internal cooling device from low-frequency operating mode to the rated operating mode according to the first control command.

[0159] (4) Figure 10 Switching schematic of operating mode of energy storage valve in energy storage valve system and working mode of internal cooling device in energy storage valve cooling system provided for embodiments of the present application Figure 4 As shown in Figure 10 the first control device can determine that the target working mode of the internal cooling device in the energy storage valve cooling system is the low-frequency working mode, and can send a second control instruction to the second control device of the energy storage valve cooling system, where the second control instruction can be used to instruct to switch the current working mode of the internal cooling device to the low-frequency working mode, so that the second control device can switch the working mode of the internal cooling device from the rated working mode to the low-frequency working mode according to the second control instruction. It should be noted that the working mode of the internal cooling device needs to be switched to the low-frequency working mode after a target time delay.

[0160] Further, in the case where the first control device detects that the operating mode of the energy storage valve in the energy storage valve system is switched from the zero-power operating mode to the peak clipping and valley filling operating mode, the first control device can determine that the target working mode of the internal cooling device in the energy storage valve cooling system is the rated working mode, and can send a first control instruction to the second control device of the energy storage valve cooling system, where the first control instruction can be used to instruct to switch the current working mode of the internal cooling device to the rated working mode, so that the second control device can switch the working mode of the internal cooling device from the low-frequency working mode to the rated working mode according to the first control instruction.

[0161] In summary, in the embodiments of the present application, the first control device of the energy storage valve system sends different control instructions to the second control device of the energy storage valve cooling system based on the switching state of the operating mode of the energy storage valve in the energy storage valve system, so as to adjust the working mode of the internal cooling device to the target working mode matched with the operating mode of the energy storage valve, so that the cooling flow of the energy storage valve cooling system can adapt to the heat generated by the energy storage valve during operation, thereby saving the power consumption of the energy storage valve cooling system and facilitating long-term and reliable operation of the battery module and the power module.
