Description

Technical Field

[0001] The present application relates to the technical field of power equipment, and in particular to a cooling method, system, intelligent terminal and storage medium for an energy storage cabinet. Background Art

[0002] An energy storage cabinet, also known as an energy storage system or energy storage unit, is a device used to store energy and release it when needed. It usually includes a battery pack, a power conversion system, a management system, and other safety and monitoring components. Its main function is to balance power supply and demand, improve energy efficiency, and serve as a backup power source.

[0003] In the related art, a liquid cooling device is usually installed in the energy storage cabinet to cool the battery pack in the energy storage cabinet. The liquid cooling device includes a cold plate, a circulating pump, a radiator and a control system. The cold plate is placed on the lower side of the battery pack. An internal channel for the coolant to pass through is opened on the cold plate. The circulating pump is connected to the internal channel and the radiator through a pipe. The control system is connected to the circulating pump and the radiator through a data wire. When the control system receives a cooling signal, it controls the circulating pump to drive the coolant to flow in the internal channel to take away the heat generated by the battery pack, and after cooling the coolant through the radiator, it circulates again, thereby continuously cooling the battery pack.

[0004] Regarding the above-mentioned related technologies, during the operation of the battery pack, there are differences in the temperatures of different battery packs. The battery packs are placed on a cold plate, and a circulating pump drives the coolant to flow in the internal channel of the cold plate to cool the battery packs uniformly. For battery packs with higher temperatures, the temperature cannot be effectively reduced. For battery packs with lower temperatures, energy consumption will increase, resulting in inconvenience in cooling the energy storage cabinet. There is still room for improvement. Summary of the invention

[0005] In order to improve the convenience of cooling an energy storage cabinet, the present application provides an energy storage cabinet cooling method, system, intelligent terminal and storage medium.

[0006] In a first aspect, the present application provides a method for cooling an energy storage cabinet, which adopts the following technical solution: A method for cooling an energy storage cabinet, comprising: Get the real-time detected temperature value of the preset battery pack; Determine whether the real-time detected temperature value meets the requirements of the preset operating temperature range; If it meets the requirements, continue to obtain the real-time temperature value of the battery pack for cyclic judgment; If not, the real-time detected temperature value and the operating temperature range are analyzed to determine the abnormal temperature value; Obtaining the cooling device serial number corresponding to the abnormal temperature value; According to the abnormal temperature value and the cooling device sequence number, the preset cooling device is controlled to cool the corresponding battery pack.

[0007] By adopting the above technical solution, when it is determined that the real-time detected temperature value does not meet the requirements of the operating temperature range, the abnormal temperature value is first determined, and then the cooling device serial number corresponding to the abnormal temperature value is identified, so that the cooling device corresponding to the cooling device serial number is controlled according to the abnormal temperature value to cool the corresponding battery pack, and the battery pack is cooled at a flow rate suitable for the battery pack, which will neither cause poor cooling effect nor excessive cooling energy consumption, thereby improving the convenience of cooling the energy storage cabinet.

[0008] Optionally, the step of controlling a preset cooling device to cool a corresponding battery pack according to the abnormal temperature value and the cooling device sequence number includes: Determine the cooling flow value according to the abnormal temperature value and the preset temperature-cooling flow relationship; Determine whether the cooling flow rate value meets the requirements of the preset cooling upper limit flow rate value; If not, the cooling device is controlled to cool the corresponding battery pack according to the preset cooling method; If it meets the requirements, the corresponding cooling device is controlled to cool the corresponding battery pack according to the cooling device sequence number and the cooling flow value.

[0009] By adopting the above technical solution, when it is determined that the coolant flow rate required by the battery pack exceeds the upper limit of the corresponding cooling device, the cooling device is controlled to cool the battery pack according to the calling cooling method; when it does not exceed, the cooling device corresponding to the cooling device serial number is controlled according to the cooling flow value to cool the battery pack, thereby ensuring that the cooling device can reduce the temperature of the battery pack and stabilize it within the normal range, thereby improving the convenience of cooling the energy storage cabinet.

[0010] Optionally, the step of controlling the corresponding cooling device to cool the corresponding battery pack according to the cooling device sequence number and the cooling flow value includes: Control the corresponding cooling device according to the cooling device sequence number to cool the corresponding battery pack with the cooling flow value; Obtain the changing stable temperature value of the battery pack; Determine whether the changing stable temperature value meets the requirements of the operating temperature range; If it meets the requirements, the corresponding cooling device is controlled to cool the corresponding battery pack with the cooling flow value according to the cooling device sequence number, and the changing stable temperature value of the battery pack is continuously obtained for cyclic judgment; If not, analyze the change stable temperature value and the operating temperature range to determine the temperature difference value; Determine the adjustment flow value according to the temperature difference value and the preset temperature difference flow relationship; The cooling flow value is adjusted according to the adjustment flow value, and the corresponding cooling device is controlled according to the cooling device sequence number to cool the corresponding battery pack with the adjusted cooling flow value.

[0011] By adopting the above technical solution, after controlling the cooling device to cool the battery pack with the cooling flow value, the changed stable temperature value of the battery pack is detected. When it is determined that the changed stable temperature value does not meet the requirements of the operating temperature range, it indicates that the cooling device cannot effectively cool the battery pack with the current flow rate. Therefore, the adjustment flow value is determined according to the temperature difference value, and after adjusting the cooling flow value with the adjusted flow value, the cooling device is controlled to cool the battery pack again with the adjusted cooling flow value, ensuring that after the temperature of the battery pack itself changes, the cooling device responds in time to change the flow rate, thereby improving the cooling effect of the cooling device.

[0012] Optionally, if the changed stable temperature value does not meet the requirements of the operating temperature range, a leak detection step for the cooling device is also included, and the specific steps include: Controlling the corresponding cooling device according to the cooling device sequence number to cool the corresponding battery pack at a preset leakage detection flow value; Obtain the real-time detection flow value of the cooling device; Determine whether the real-time detection flow value meets the requirements of the leak detection flow value; If it meets the requirement, the cooling device is controlled to cool the corresponding battery pack according to the changed stable temperature value; If it does not meet the requirements, an alarm will be issued based on the cooling device serial number and the preset leakage prompt information.

[0013] By adopting the above technical solution, when it is determined that the changing stable temperature value does not meet the requirements of the operating temperature range, the cooling device is controlled to cool the battery pack with the leakage detection flow value, and the real-time detection flow value of the cooling device is detected. When it is determined that the real-time detection flow value is inconsistent with the leakage detection flow value, it indicates that there is a coolant leakage, which causes the cooling device to be unable to effectively reduce the battery pack temperature. Therefore, a prompt is given according to the cooling device serial number and leakage prompt information, thereby ensuring that personnel can repair the damaged cooling device in time.

[0014] Optionally, the step of controlling the cooling device to cool the corresponding battery pack according to the preset calling cooling method includes: The amount of traffic obtained exceeds the number of devices; Determine whether the flow rate exceeds the number of devices and meets the requirements of the preset total number of devices; If it meets the requirements, the cooling device is controlled to cool the corresponding battery pack according to the preset shared cooling method; If it does not match, the calling device serial number is determined according to the relationship between the cooling device serial number and the preset calling serial number; According to the cooling device serial number and the calling device serial number, the cooling device and the preset auxiliary device are controlled to cool the corresponding battery pack respectively.

[0015] By adopting the above technical solution, when the flow rate exceeds the number of devices and meets the requirement of the total number of devices, it means that the flow rate of all cooling devices cannot meet the cooling demand, so the cooling devices are controlled to cool the battery pack according to the shared cooling method; when it does not meet the requirement, it means that only some cooling devices cannot meet the cooling demand, so the auxiliary device is called according to the calling device serial number to assist the cooling device in cooling the battery pack, thereby improving the cooling effect of the cooling device.

[0016] Optionally, the step of controlling the cooling device and the preset auxiliary device to cool the corresponding battery pack according to the cooling device serial number and the calling device serial number includes: Control the cooling device according to the cooling device sequence number to cool the corresponding battery pack at the cooling upper limit flow value; Analyze the cooling flow value and the cooling upper limit flow value to determine the calling flow value; The auxiliary device is controlled to move to a preset standard cooling position according to the calling device serial number, and the auxiliary device is controlled to call the flow value to assist in cooling the corresponding battery pack.

[0017] By adopting the above technical scheme, the cooling device corresponding to the cooling device serial number is controlled to cool the battery pack at the cooling upper limit flow value, and the auxiliary device is controlled to assist in cooling the battery pack at the standard cooling position according to the called flow value, so that the flow value for cooling the battery pack meets the effective cooling flow value, thereby improving the cooling effect on the battery pack.

[0018] Optionally, the step of controlling the cooling device to cool the corresponding battery pack according to the preset shared cooling method includes: Control the cooling device according to the cooling device sequence number to cool the corresponding battery pack at the cooling upper limit flow value; Analyze the cooling flow value and the cooling upper limit flow value to determine the flow excess value; Analyze the relationship between the flow rate excess value, the corresponding cooling device serial number and the preset call serial number to determine the exclusive device serial number and the shared device serial number; Control the preset auxiliary device to move to the preset standard cooling position according to the exclusive device serial number, and control the auxiliary device to assist in cooling the corresponding battery pack with the flow rate exceeding the value; Analyze the shared device serial numbers and the corresponding flow excess values ​​to determine the shared flow value and the serial number movement ratio; The auxiliary device is controlled to move to a preset shared cooling position according to the shared device serial number and the serial number movement ratio, and the auxiliary device is controlled to assist in cooling the corresponding battery pack with the shared flow value.

[0019] By adopting the above technical scheme, the exclusive device serial number and the shared device serial number are determined according to the flow excess value, so that the corresponding auxiliary device is controlled to move to the standard cooling position according to the exclusive device serial number, and the battery pack is assisted in cooling with the flow excess value, and the auxiliary device corresponding to the shared device serial number is controlled to move to the shared cooling position according to the serial number movement ratio, and the battery pack is assisted in cooling with the shared flow value, thereby ensuring that all battery packs can be effectively cooled, thereby improving the cooling effect of the cooling device.

[0034] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 7 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] The embodiment of the present application discloses a method for cooling an energy storage cabinet, and specifically discloses a processing terminal, a battery pack status sensor and a cooling device. The processing terminal is respectively connected to the battery pack status sensor and the cooling device through data wires to realize data interaction and control. When the processing terminal receives the real-time detection temperature value detected by the battery pack status sensor, when the processing terminal determines that the real-time detection temperature value meets the requirements of the operating temperature range, the processing terminal controls the battery pack status sensor to continue to detect the real-time detection temperature value of the battery pack, thereby continuously monitoring the temperature condition of the battery pack; when it does not meet the requirements, the processing terminal identifies the abnormal temperature value and the cooling device serial number corresponding to the abnormal temperature value, thereby controlling the cooling device corresponding to the cooling device serial number according to the abnormal temperature value to cool the battery pack, and cooling the battery pack at a flow rate suitable for the battery pack, which will neither cause poor cooling effect nor excessive cooling energy consumption, thereby improving the convenience of cooling the energy storage cabinet.

[0036] Reference Figure 1 , the embodiment of the present application discloses a method for cooling an energy storage cabinet, comprising the following steps: Step S100: obtaining a real-time detected temperature value of a preset battery pack.

[0037] The battery pack refers to the battery used to store and release energy in the energy storage cabinet. A plurality of battery packs are usually arranged in an energy storage cabinet. The real-time detection temperature value refers to the operating temperature value of the battery pack, which is detected by the temperature sensor and sent to the processing terminal.

[0038] Step S101: determine whether the real-time detected temperature value meets the requirements of the preset operating temperature range.

[0039] The operating temperature range refers to the temperature range for normal operation of the battery pack. The specific value is determined by the operator based on the actual situation of the battery pack. The operating temperature range requirement refers to being within the operating temperature range, which is input by the operator and stored in the processing terminal.

[0040] The processing terminal determines whether the real-time detected temperature value is within the operating temperature range, thereby determining whether the operating temperature of the battery pack is normal.

[0041] Step S1011: If the conditions are met, continue to obtain the real-time temperature value of the battery pack for cyclic determination.

[0042] Among them, if the processing terminal determines that the real-time detected temperature value is within the operating temperature range, it indicates that the operating temperature of the battery pack is normal, so there is no need for a cooling device to cool the battery pack, thereby continuing to control the temperature sensor to detect the real-time detected temperature value of the battery pack to continuously monitor the temperature changes of the battery pack.

[0043] Step S1012: If not, the real-time detected temperature value and the operating temperature range are analyzed to determine the abnormal temperature value.

[0044] Among them, if the processing terminal determines that the real-time detected temperature value is not within the operating temperature range, it indicates that the operating temperature of the battery pack is abnormal. Therefore, the abnormal temperature value is determined based on the real-time detected temperature value and the operating temperature range to provide data support for subsequent cooling of the battery pack.

[0045] The abnormal temperature value refers to the temperature value of the battery pack that exceeds the normal temperature, which is obtained by calculating the difference between the real-time detection temperature value and the maximum value of the operating temperature range by the processing terminal.

[0046] Step S102: Obtain the cooling device serial number corresponding to the abnormal temperature value.

[0047] Among them, the cooling device serial number refers to the device serial number for cooling the battery pack with abnormal temperature. The processing terminal identifies the battery pack serial number suffixed with the abnormal temperature value, and thus calls the cooling device serial number corresponding to the abnormal temperature value based on the one-to-one correspondence between the battery pack serial number and the cooling device serial number.

[0048] Step S103: controlling a preset cooling device to cool the corresponding battery pack according to the abnormal temperature value and the cooling device sequence number.

[0049] After the processing terminal determines the cooling device serial number, the processing terminal controls the cooling device corresponding to the cooling device serial number to cool the battery pack according to the abnormal temperature value. The specific method is as follows Figure 2 steps, so that each battery pack can be cooled individually with an appropriate flow rate, which can avoid ineffective cooling on the one hand and reduce energy consumption on the other.

[0050] A cooling device refers to a device for cooling a battery pack. In the present application, liquid cooling is adopted, including a cold plate, a circulating pump, a radiator and a valve. A fixed pipe is arranged inside the cold plate, and the fixed pipe corresponds to each battery pack and is used to cool each battery pack; each fixed pipe is opened and closed by a separate valve, thereby controlling the flow rate of coolant in each pipe; the circulating pump is connected to each fixed pipe through a main pipe and a branch pipe, and the other end of the circulating pump is connected to the radiator, and the other end of the radiator is connected to the fixed pipe, thereby realizing the circulation of heat absorption and heat dissipation of the coolant, and the coolant adopts an ethylene glycol aqueous solution.

[0051] Reference Figure 2 The step of controlling a preset cooling device to cool a corresponding battery pack according to an abnormal temperature value and a cooling device sequence number includes: Step S200: determining a cooling flow rate value according to an abnormal temperature value and a preset temperature-cooling flow rate relationship.

[0052] The temperature-cooling flow relationship refers to the proportionality coefficient between the abnormal temperature and the cooling flow, and the proportionality coefficient is determined by the operator based on the product of the heat exchange area of ​​the pipeline in the cooling device and the heat transfer coefficient.

[0053] The cooling flow value refers to the flow of the coolant in the cooling device, which is obtained by calculating the product of the abnormal temperature value and the coefficient corresponding to the temperature-cooling flow relationship by the processing terminal.

[0054] Step S201: Determine whether the cooling flow rate value meets the requirement of the preset cooling upper limit flow rate value.

[0055] Among them, the cooling upper limit flow value refers to the maximum flow of the fixed pipeline in the cooling device, which is determined by the operator according to the actual situation of the fixed pipeline. The requirement of the cooling upper limit flow value means not exceeding the cooling upper limit flow value.

[0056] The processing terminal determines whether the cooling flow value does not exceed the cooling upper limit flow value, thereby determining whether the fixed pipeline can complete the cooling work of the battery pack.

[0057] Step S2011: If not, control the cooling device to cool the corresponding battery pack according to a preset cooling method.

[0058] If the processing terminal determines that the cooling flow rate value exceeds the cooling upper limit flow rate value, it indicates that the battery pack cannot be cooled down by relying solely on the fixed pipeline. Therefore, the cooling device is controlled to cool the battery pack according to the cooling method. The specific method is referred to Figure 5 steps.

[0059] The cooling method refers to the method of calling the mobile pipe in the cooling device to assist the fixed pipe to complete the cooling work. The operator stores it in the processing terminal. For specific methods, refer to Figure 5 steps.

[0060] Step S2012: If it is met, the corresponding cooling device is controlled to cool the corresponding battery pack according to the cooling device serial number and the cooling flow value.

[0061] If the processing terminal determines that the cooling flow rate value does not exceed the cooling upper limit flow rate value, it indicates that the battery pack can be cooled by the fixed pipeline. Therefore, the cooling device corresponding to the cooling device serial number is controlled according to the cooling flow rate value to cool the battery pack. For specific methods, refer to Figure 3 steps.

[0062] Reference Figure 3 The step of controlling the corresponding cooling device to cool the corresponding battery pack according to the cooling device sequence number and the cooling flow value includes: Step S300: controlling the corresponding cooling device to cool the corresponding battery pack at a cooling flow value according to the cooling device sequence number.

[0063] Among them, the processing terminal controls the valve on the corresponding fixed pipeline in the cooling device to open at an opening corresponding to the cooling flow value according to the cooling device serial number, so that under the drive of the cooling device circulation pump, the coolant flows in the fixed pipeline to exchange heat with the battery pack to take away the heat generated by the battery pack, thereby cooling the battery pack.

[0064] Step S301: Obtain the changing stable temperature value of the battery pack.

[0065] The changing stable temperature value refers to a temperature value of the battery pack that is gradually stabilized under the cooling effect of the cooling device, and is obtained by the processing terminal recording the temperature curve of the battery pack and identifying the stable temperature value.

[0066] Step S302: Determine whether the changed stable temperature value meets the requirements of the operating temperature range.

[0067] The requirement for the operating temperature range in this step is consistent with the requirement for the operating temperature range in step S101, and will not be elaborated here.

[0068] The processing terminal determines whether the changed stable temperature value is within the operating temperature range, thereby determining whether the cooling device is effective in cooling the battery pack.

[0069] Step S3021: If it is in compliance, then continue to control the corresponding cooling device according to the cooling device sequence number to cool the corresponding battery pack with the cooling flow value, and continue to obtain the changing stable temperature value of the battery pack for cyclic judgment.

[0070] Among them, if the processing terminal determines that the changed stable temperature value is within the operating temperature range, it indicates that the cooling device is effective in cooling the battery pack. Therefore, the corresponding cooling device continues to be controlled according to the cooling device serial number to cool the corresponding battery pack with the cooling flow value, and the changing temperature value of the battery pack continues to be detected, thereby continuously monitoring the temperature changes of the battery pack.

[0071] Step S3022: If not, analyze the changing stable temperature value and the operating temperature range to determine the temperature difference value.

[0072] Among them, if the processing terminal determines that the changing stable temperature value is not within the operating temperature range, it means that the cooling device has not achieved the expected effect on cooling the battery pack. Therefore, the temperature difference value is determined based on the changing stable temperature value and the operating temperature range to provide data support for the subsequent cooling of the cooling device.

[0073] The temperature difference value refers to the difference between the changing stable temperature value and the operating temperature range, and is determined by the processing terminal calculating the difference between the changing stable temperature value and the maximum value in the operating temperature range.

[0074] Step S303: determining an adjusted flow value according to the temperature difference value and a preset temperature difference flow relationship.

[0075] Among them, the temperature difference flow relationship in this step is actually consistent with the temperature cooling flow relationship in step S200, and will not be repeated here.

[0076] The adjusted flow value refers to the flow value that the cooling device needs to increase, which is obtained by calculating the product of the temperature difference value and the coefficient corresponding to the temperature difference flow relationship by the processing terminal.

[0077] Step S304: adjusting the cooling flow value according to the adjustment flow value, and controlling the corresponding cooling device according to the cooling device sequence number to cool the corresponding battery pack with the adjusted cooling flow value.

[0078] Among them, after the processing terminal determines the adjustment flow value, the adjustment flow value is added on the basis of the cooling flow value, thereby adjusting the cooling flow value, and controlling the valve of the fixed pipeline in the cooling device corresponding to the cooling device serial number to open with the opening corresponding to the adjusted cooling flow value, thereby adjusting the cooling effect on the battery pack.

[0079] Reference Figure 4 If the stable temperature value does not meet the requirements of the operating temperature range, the cooling device is also leak-checked. The specific steps include: Step S400: controlling the corresponding cooling device according to the cooling device sequence number to cool the corresponding battery pack at a preset leakage detection flow value.

[0080] Among them, when it is determined that the changing stable temperature value exceeds the operating temperature range, it indicates that the cooling effect of the cooling device on the battery pack does not meet the expectations. Therefore, the processing terminal controls the valve of the fixed pipeline in the cooling device according to the cooling device serial number to open at an opening corresponding to the leak detection flow value, thereby circulating the coolant, providing data support for subsequent inspections of whether there is coolant leakage in the cooling device.

[0081] The leak detection flow value refers to the flow value when checking whether there is leakage in the cooling device. The specific value is determined by the operator based on the actual situation.

[0082] Step S401: obtaining the real-time detection flow value of the cooling device.

[0083] The real-time detected flow value refers to the flow value actually detected at the outlet of the fixed pipeline in the cooling device, which is detected by the flow meter and sent to the processing terminal.

[0084] Step S402: Determine whether the real-time detection flow value meets the requirement of the leak detection flow value.

[0085] The requirement of the leak detection flow value is to be consistent with the leak detection flow value. The processing terminal determines whether the real-time detection flow value is consistent with the leak detection flow value, thereby determining whether the flow values ​​of the fixed pipeline inlet and outlet are consistent.

[0086] Step S4021: If it is met, the cooling device is controlled to cool the corresponding battery pack according to the changed stable temperature value.

[0087] Among them, if the processing terminal determines that the real-time detection flow value is consistent with the leakage detection flow value, it indicates that there is no coolant leakage in the cooling device, and the cooling effect on the battery pack does not meet the expectations only because of insufficient flow. Therefore, the cooling device is controlled to cool the battery pack according to the changing stable temperature value, that is, Figure 3 Steps in .

[0088] Step S4022: If it does not meet the requirements, an alarm is issued according to the cooling device serial number and the preset leakage prompt information.

[0089] Among them, if the processing terminal determines that the real-time detection flow value is inconsistent with the leakage detection flow value, it indicates that there is a leak in the cooling device. Therefore, the cooling device serial number is displayed in the form of text or voice according to the leakage prompt information, thereby prompting personnel to repair the cooling device.

[0090] The liquid leakage prompt information refers to information prompting liquid leakage, which is stored in the processing terminal by the operator.

[0091] Reference Figure 5 The step of controlling the cooling device to cool the corresponding battery pack according to the preset cooling method includes: Step S500: Obtain the number of devices that exceed the flow rate.

[0092] The flow exceeding device quantity refers to the quantity by which the coolant flow required by the battery pack exceeds the upper limit flow of the corresponding cooling device, which is accumulated by the processing terminal when it determines that the cooling flow value does not meet the requirement of the cooling upper limit flow value.

[0093] Step S501: Determine whether the flow rate exceeds the number of devices and meets the preset requirement of the total number of devices.

[0094] Among them, the total number of devices refers to the total number of all cooling devices. The specific value is determined by the operator based on the actual situation of the cooling device. The requirement for the total number of devices means that it is equal to the total number of devices.

[0095] The processing terminal determines whether the number of flow-exceeding devices is equal to the total number of devices, thereby determining whether each battery pack requires an auxiliary device for auxiliary cooling.

[0096] Step S5011: If it is in compliance, the cooling device is controlled to cool the corresponding battery pack according to a preset shared cooling method.

[0097] If the processing terminal determines that the flow exceeds the number of devices equal to the total number of devices, it means that all battery packs need auxiliary devices for auxiliary cooling. Therefore, the cooling device is controlled to cool the battery pack according to the shared cooling method. The specific method is as follows Figure 7 steps.

[0098] The shared cooling method refers to a method in which one auxiliary device simultaneously assists two cooling devices in cooling. For specific methods, refer to Figure 7 steps.

[0099] Step S5012: If not, determine the calling device serial number according to the relationship between the cooling device serial number and the preset calling serial number.

[0100] Among them, the calling serial number relationship refers to the corresponding relationship between the cooling device serial number and the auxiliary device serial number. One auxiliary device is set for two cooling devices. Therefore, the cooling device in the edge part corresponds to one auxiliary device, and the cooling device in the middle part corresponds to two auxiliary devices. The cooling device in the edge part enjoys the priority of allocating auxiliary devices, that is, when an edge cooling device and an adjacent cooling device both need auxiliary devices, the auxiliary device between the two will be allocated to the edge cooling device in priority, and the adjacent cooling device can consider allocating the auxiliary device between the other cooling device. The operator forms a mapping table after matching the cooling device with the auxiliary device.

[0101] If the processing terminal determines that the flow exceeds the number of devices and is not equal to the total number of devices, it means that only some battery packs need auxiliary devices for auxiliary cooling. Therefore, the calling device number is found in the mapping table corresponding to the calling number relationship according to the cooling device number.

[0102] The calling device serial number refers to the serial number of the auxiliary device that needs to be called, and is obtained by searching the mapping table corresponding to the calling serial number relationship according to the cooling device serial number by the processing terminal.

[0103] Step S502: Control the cooling device and the preset auxiliary device to cool the corresponding battery pack according to the cooling device serial number and the calling device serial number.

[0104] Among them, after determining the calling device serial number, the processing terminal controls the cooling device to cool the battery pack according to the cooling device serial number, and controls the auxiliary device to assist in cooling the battery pack according to the calling device serial number. The specific method is referred to Figure 6 steps.

[0105] The auxiliary device refers to a device that assists the cooling device in cooling the battery pack. In the present application, liquid cooling is adopted, including a mobile pipe and a linear module. The mobile pipe is controlled by the linear module to move between two fixed pipes, thereby assisting the fixed pipe to cool down by adjusting the position; each mobile pipe is opened and closed by a separate valve to control the flow of coolant in each pipe; the circulating pump is connected to the mobile pipe through a main pipe and a branch pipe, the other end of the circulating pump is connected to the radiator, and the other end of the radiator is connected to the mobile pipe, thereby realizing the circulation of heat absorption and heat dissipation of the coolant, and the coolant adopts an ethylene glycol aqueous solution.

[0106] Reference Figure 6 The steps of controlling the cooling device and the preset auxiliary device to cool the corresponding battery pack according to the cooling device serial number and the calling device serial number include: Step S600: Controlling the cooling device to cool the corresponding battery pack at the cooling upper limit flow value according to the cooling device sequence number.

[0107] Among them, the processing terminal controls the cooling device according to the cooling device sequence number to cool the battery pack at the cooling upper limit flow value, thereby fully realizing the cooling function of the cooling device and reducing the difficulty of cooling the subsequent auxiliary device.

[0108] Step S601: Analyze the cooling flow value and the cooling upper limit flow value to determine the calling flow value.

[0109] The call flow value refers to the coolant flow rate required by the auxiliary device, which is determined by the difference between the cooling flow value calculated by the processing terminal and the cooling upper limit flow value.

[0110] Step S602: Control the auxiliary device to move to a preset standard cooling position according to the calling device serial number, and control the auxiliary device to call the flow value to assist in cooling the corresponding battery pack.

[0111] Among them, after the processing terminal determines the calling device serial number, it controls the auxiliary device corresponding to the calling device serial number to move to the standard cooling position, and controls the valve in the auxiliary device to open according to the calling flow value, thereby making up for the flow that the cooling device cannot provide, so as to achieve effective cooling of the battery pack.

[0112] The standard cooling position refers to the position for auxiliary cooling of a single battery pack. Each auxiliary device has two standard cooling positions, which correspond to the cooling device serial numbers respectively. The processing terminal determines which standard cooling position the auxiliary device moves to based on the cooling device serial number.

[0113] Reference Figure 7 The step of controlling the cooling device to cool the corresponding battery pack according to the preset shared cooling method includes: Step S700: Controlling the cooling device to cool the corresponding battery pack at the cooling upper limit flow rate value according to the cooling device sequence number.

[0114] Among them, the processing terminal controls the cooling device according to the cooling device sequence number to cool the battery pack at the cooling upper limit flow value, thereby fully realizing the cooling function of the cooling device and reducing the difficulty of cooling the subsequent auxiliary device.

[0115] Step S701: Analyze the cooling flow rate value and the cooling upper limit flow rate value to determine the flow rate excess value.

[0116] The flow excess value refers to the value by which the flow required by the battery pack exceeds the upper limit flow of the cooling device, and is determined by the difference between the cooling flow value and the cooling upper limit flow value calculated by the processing terminal.

[0117] Step S702: Analyze the relationship between the flow excess value, the corresponding cooling device serial number and the preset call serial number to determine the exclusive device serial number and the shared device serial number.

[0118] Among them, the exclusive device serial number refers to the serial number of the auxiliary device that only assists one cooling device, and the shared device serial number refers to the serial number of the auxiliary device that assists two cooling devices at the same time. There is only one shared device serial number, and the remaining auxiliary devices are all devices corresponding to the exclusive device serial number. The processing terminal calculates the sum of the flow excess values ​​corresponding to adjacent serial numbers according to the cooling device serial number. If the sum does not exceed the upper limit flow value of the auxiliary device, the auxiliary devices between the adjacent serial numbers are defined as shared devices, and the processing terminal searches for the serial number corresponding to the auxiliary device in the mapping table corresponding to the calling serial number relationship according to the cooling device serial number, and defines the serial number as a shared device serial number, while other serial numbers are exclusive device serial numbers.

[0119] The calling sequence number relationship in this step is consistent with the calling sequence number relationship in step S5012, and will not be repeated here.

[0120] Step S703: controlling the preset auxiliary device to move to the preset standard cooling position according to the exclusive device serial number, and controlling the auxiliary device to assist in cooling the corresponding battery pack with the flow rate exceeding the value.

[0121] Among them, after determining the exclusive device serial number, the processing terminal controls the corresponding auxiliary device to move to the standard cooling position according to the exclusive device serial number, and controls the valve of the auxiliary device to open according to the flow excess value, thereby making up for the flow that the cooling device cannot provide, so as to achieve effective cooling of the battery pack.

[0122] The auxiliary device in this step is the same as the auxiliary device in step S502, and will not be described in detail here.

[0123] Step S704: Analyze the shared device serial number and the corresponding flow excess value to determine the shared flow value and the serial number movement ratio.

[0124] The shared flow value refers to the flow value of the shared auxiliary device, which is obtained by calculating the sum of the two flow excess values ​​corresponding to the shared device serial number by the processing terminal. The serial number movement ratio refers to the distance ratio of the auxiliary device adjusted at the shared cooling position, which is obtained by calculating the ratio of the two flow excess values ​​by the processing terminal.

[0125] Step S705: controlling the auxiliary device to move to a preset shared cooling position according to the shared device serial number and the serial number movement ratio, and controlling the auxiliary device to assist in cooling the corresponding battery pack with the shared flow value.

[0126] Among them, after the processing terminal determines the serial number movement ratio, the processing terminal controls the auxiliary device to move to the shared cooling position according to the shared device serial number, and adjusts it according to the serial number movement ratio, and controls the valve opening of the auxiliary device according to the shared flow value, so that the flow of the auxiliary device is distributed to the two adjacent battery groups in a corresponding proportion, thereby making up for the flow that the cooling device cannot provide, so as to achieve effective cooling of the battery group.
