Description

Technical Field

[0001] This invention belongs to the field of energy storage technology and relates to an energy storage thermal management and control method, system, equipment and storage medium. Background Technology

[0002] With the rapid development of renewable energy and the widespread adoption of electric vehicles, energy storage batteries, as core components for energy storage and release, have attracted significant attention regarding their performance and safety. However, energy storage batteries generate a large amount of heat during operation. If this heat cannot be dissipated in time, it will cause the battery temperature to rise, potentially leading to thermal runaway, capacity degradation, or even safety accidents. Therefore, battery thermal management technology has become crucial for ensuring the safe and stable operation of energy storage systems.

[0003] Currently, common battery thermal management methods mainly include air cooling, liquid cooling, phase change material cooling, and heat pipe cooling. Air cooling technology removes heat through airflow, offering advantages such as simple structure and low cost, but its heat dissipation efficiency is relatively low, making it difficult to meet the heat dissipation requirements of high-power-density batteries. Liquid cooling technology utilizes the high heat capacity of liquid media to effectively reduce battery temperature, but its system is complex, costly, and carries the risk of leakage. Phase change material cooling absorbs heat through material phase change, offering the advantage of uniform temperature control, but phase change materials have poor thermal conductivity, making rapid heat dissipation difficult. Heat pipe cooling utilizes the highly efficient thermal conductivity of heat pipes to achieve rapid heat conduction, but its design and manufacturing processes are complex and costly.

[0004] While existing technologies can alleviate battery temperature rise to some extent, most employ uniform heat dissipation methods, failing to provide precise cooling for individual batteries within the battery pack that generate significantly more heat. In practical applications, due to performance differences between individual battery cells, some cells may generate more heat due to higher internal resistance or unbalanced loads. If these high-heat-generating cells are not specifically cooled, localized overheating will occur, impacting the performance and lifespan of the entire battery pack. Therefore, developing an electrical control method capable of specifically cooling high-heat-generating batteries has significant practical implications and application value. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art and provide an energy storage thermal management and control method, system, device and storage medium.

[0006] To achieve the above objectives, the present invention employs the following technical solution: A thermal management and control method for energy storage includes the following steps: The battery pack is divided into temperature zones, and the real-time temperature of each zone is obtained. The real-time temperature of each temperature zone is compared with a preset first temperature threshold, and red temperature zones with real-time temperatures higher than the first temperature threshold are selected. Based on the location distribution of red-temperature communities, adjacent red-temperature communities are merged into red-temperature connected areas, and multiple red-temperature areas are formed based on the merging results. Compare the heat of each red temperature zone to determine the red temperature zone with the highest current temperature; Based on the location and temperature value of the red temperature zone with the highest current temperature, calculate the optimal position of the fan on the preset guide rail; Based on the optimal position of the fan on the preset guide rail, a movement path is generated, and heat dissipation commands are executed.

[0007] A further improvement of the present invention is that: The step of dividing the battery pack into temperature zones and obtaining the real-time temperature of each zone includes: A rectangular cover is installed on the outside of the battery pack. A vertical partition is set between two horizontally adjacent battery cells, and a horizontal partition is set between two vertically adjacent battery cells. Each region has at least one battery cell. Temperature sensors installed on the battery cells obtain the real-time temperature of each temperature region. The minimum quadrilateral area formed by the combination of the horizontal partition, vertical partition, and cover is defined as the temperature region.

[0008] The process involves merging adjacent red-temperature cells into a series of red-temperature zones based on their location distribution, resulting in multiple red-temperature zones, including: Obtain the location distribution of M red temperature cells in the battery pack plane, and determine whether there is a shared partition between two adjacent red temperature cells; When there is a shared partition, the adjacent red temperature cells are merged into a red temperature series area. The total number of all red temperature series areas is N, and the total number of red temperature cells in N red temperature series areas is G. The number of red-temperature regions, K, is calculated as: M - G + N.

[0009] The step of comparing the heat of each red temperature zone to determine the red temperature zone with the highest current temperature includes: Based on the real-time temperature of each red-temperature cell, the temperature of each red-temperature region is obtained. Combined with the area S of the red-temperature region, the simulated heat H of each red-temperature region is calculated. By comparing the simulated heat H of each red temperature region, the red temperature region with the highest current temperature is determined.

[0010] The calculation of the optimal position of the fan on the preset guide rail based on the location and temperature value of the area with the highest current red temperature includes: Once the red temperature region with the highest current temperature is identified, the temperature Ti of the i-th temperature region is compared with the preset second temperature threshold. Regions with temperatures Ti less than the second temperature threshold are marked as supercooled regions, where the second temperature threshold is less than the first temperature threshold. Select the supercooled area that shares an adjacent partition with the red temperature area with the highest current temperature, and connect the selected supercooled area with the red temperature area with the highest current temperature to form the final heat dissipation area. The optimal position of the fan on the preset guide rail is calculated based on the final heat dissipation area.

[0011] The calculation of the optimal position of the fan on the preset guide rail based on the final heat dissipation area includes: Based on the location and temperature of the final heat dissipation area, calculate the simulated position of the fan. , ):

[0027] The present invention will now be described in further detail with reference to the accompanying drawings: Example 1 See Figure 1 This invention discloses an energy storage thermal management and control method, comprising the following steps: Step 1: Divide the battery pack into multiple temperature zones, each zone containing at least one battery cell. Obtain the temperature readings using temperature sensors installed on the battery cells. i Temperature of each temperature zone T i .

[0028] Specifically, the following steps are included: A rectangular cover is installed on the outside of the battery pack. A vertical partition is set between two horizontally adjacent battery cells, and a horizontal partition is set between two vertically adjacent battery cells. The temperature zone is the smallest quadrilateral area formed by the combination of the horizontal partition, the vertical partition, and the cover.

[0029] Step 2: Place the first i Temperature of each temperature zone T i Compared with a preset first temperature threshold, M red temperature zones with temperatures higher than the first temperature threshold are selected.

[0030] Step 3: Through M The location distribution of each red-temperature zone was obtained M-G+N A red-temperature zone, N The number of red-temperature series regions that have at least one overlapping plate. N The red temperature series area is composed of G A red-temperature community has been formed.

[0031] Specifically, the following steps are included: By numbering the horizontal and vertical partitions sequentially, we obtain the number... i The transverse partition and the first Between the transverse partitions, the first j Vertical partition and the first j+1 The smallest quadrilateral enclosed by the vertical partitions is numbered as follows: By M By comparing the numbers of the red-temperature communities, we can obtain... N The calculated red temperature series region, which has at least one overlapping plate, is the red temperature region formed after recombination. M-G+N indivual.

[0032] Step 4: By comparison M-G+N The heat level of each red temperature zone is used to identify the red temperature zone with the most severe heat. Specifically, the following steps are included: By comparison M-G+N The method for identifying the most severely overheated red-temperature zone by measuring the heat intensity of each zone is as follows: MThe temperature of each red-temperature zone is obtained from the temperature of each red-temperature cell, and the simulated heat of each red-temperature zone is calculated. H By comparing the simulated heat in each red temperature region H The size of the red temperature area is used to identify the area with the most severe overheating. Finally, the overlapping horizontal or vertical partitions within the area with the most severe overheating are removed to obtain the number of the red temperature area with the most severe overheating. Simulated heat

[0034] Step 5: Determine the optimal position of the fan based on the location and temperature value of the area with the most severe overheating. Specifically, the following steps are included: After identifying the area with the most severe fever (red temperature zone), the first... i Temperature of each temperature zone T i Compare with a preset second temperature threshold to filter out F A supercooled region, by... F The numbers of the supercooled areas are compared with the numbers of the red-temperature areas with the most severe heat generation. The final heat dissipation area is obtained by combining adjacent overlapping partitions, wherein the second temperature threshold is less than the first temperature threshold.

[0035] Furthermore, based on the location and temperature of the final heat dissipation area, the simulated location of the fan is calculated. , The specific formula is as follows:

[0036]

[0037] in,( , ) is the first i Location coordinates of the Hongwen residential area; Furthermore, the final position of the fan is obtained based on the simulated position of the fan: By identifying the location of the most severely overheated red-temperature zone, a heat dissipation zone corresponding to the red-temperature zone is obtained. The final position of the fan is then determined based on its optimal position. Specifically, this is achieved by simulating the fan's position... , The location of the fan is compared with the location of the heat dissipation area, and the location of the nearest heat dissipation area is taken as the final location of the fan.

[0038] In this embodiment, the heat dissipation zone is a plurality of discrete docking positions preset on the guide rail. The guide rail is provided with a plurality of positioning points that correspond to the spatial positions of each temperature region in the battery pack. Each positioning point is a heat dissipation zone.

[0039] Step 6: The controller generates a control signal based on the calculated optimal position, driving the fan to move along the guide rail to the target position; and dynamically adjusts the fan speed according to the temperature value of the temperature zone.

[0040] Example 2 This invention discloses an energy storage thermal management and control method. Specifically, the following steps are included: Step 1: Divide the battery pack into multiple temperature zones, each zone containing one battery cell.

[0041] In this embodiment of the invention, the battery pack adopts a rectangular array arrangement, with each battery cell having the same lateral and axial spacing. Theoretically, by using separators, each temperature zone is independent, and heat dissipation within each zone is also independent, minimizing heat transfer between zones and facilitating heat management. Specifically, temperature sensors installed on the battery cells can obtain the temperature data of the first... i Temperature of each temperature zone T i .

[0042] Step 2: Place the first i Temperature of each temperature zone T i Compared with the preset first temperature threshold, the first temperature threshold is basically close to the battery's high-temperature protection temperature, such as... Figure 1 As shown, it is possible to filter out temperatures greater than the first temperature threshold. M There are 5 red-temperature zones in the diagram. A red-temperature zone represents an area that can be cooled down because it has met the conditions for cooling. The other zones have not met the conditions for cooling down and do not require heat dissipation.

[0043] Furthermore, among the five red-temperature zones, there are two red-temperature areas. One red-temperature area consists of three adjacent red-temperature zones, and the other consists of two adjacent red-temperature zones. Connecting adjacent red-temperature zones allows for... M The location distribution of each red-temperature zone was obtained M-G+N A red-temperature zone; Assuming the area of ​​a single red-temperature zone is one unit, then N The number of regions with an area greater than one unit. NThe number of red-temperature series regions that have at least one overlapping plate. N The red temperature series area is composed of G A red-temperature community has formed here. N= 2 .

[0044] This invention effectively solves the misjudgment problem caused by the synergistic effect of adjacent heat-generating zones by introducing a red-temperature series region fusion algorithm. For example, when multiple red-temperature zones share a heat insulation panel, the system can automatically identify them as a unified thermal management unit, avoiding duplicate responses or resource conflicts, thereby improving heat dissipation efficiency. This spatial topology analysis capability enables the system to maintain stable temperature control accuracy even in complex battery arrays.

[0045] Step 3: By comparison M-G+N The heat level of each red-temperature zone is used to identify the area with the most severe overheating. This most severe overheating zone can be measured by the degree of heat accumulation per unit time. The heat accumulation in each zone over a period of time is calculated by integration. The greater the heat accumulation, the longer the overheating problem persists in that area, which may have a greater impact on battery life. This area is currently the most severely overheated red-temperature zone.

[0046] Step 4: Based on the location and temperature value of the area with the most severe overheating, determine the optimal position of the fan; the controller generates a control signal based on the calculated optimal position to drive the fan to move along the guide rail to the target position.

[0047] By identifying the hottest red-temperature areas and placing fans in optimal positions, concentrated heat dissipation can be directly applied to these high-temperature regions, avoiding the waste of heat dissipation resources inherent in traditional uniform cooling methods. This precise cooling approach significantly improves heat dissipation efficiency and effectively reduces the temperature of high-temperature areas. Localized overheating is one of the main causes of battery thermal runaway. By placing fans in optimal positions, the temperature of high-temperature areas can be rapidly reduced, decreasing the risk of thermal runaway and improving the safety and reliability of the energy storage system.

[0048] Furthermore, the fan speed is dynamically adjusted based on the temperature value of the temperature zone. By monitoring the temperature value of the temperature zone in real time and dynamically adjusting the fan speed, the fan speed can be increased to enhance the heat dissipation effect when the temperature is high, and decreased to reduce energy consumption when the temperature is low. This intelligent heat dissipation method significantly improves heat dissipation efficiency and avoids the problems of insufficient or excessive heat dissipation in the traditional fixed speed mode. Dynamically adjusting the fan speed can flexibly adjust the power output according to the actual heat dissipation needs, avoiding energy waste caused by the fan running at high speed for a long time. Reducing the speed when the temperature is low can effectively reduce system energy consumption and improve overall energy efficiency.

[0049] Furthermore, in this embodiment, the battery pack is divided into multiple temperature zones as follows: The bottom of the battery pack is constructed with a ventilation panel, while the fan is mounted on top. A rectangular cover is installed on the outside of the battery pack to shield the outer surface, making it easier for the internal areas to dissipate heat. Vertical partitions are placed between horizontally adjacent battery cells, and horizontal partitions are placed between vertically adjacent battery cells. The temperature zone is the smallest quadrilateral area formed by the combination of the horizontal and vertical partitions and the cover. By dividing the battery pack into multiple small zones, precise temperature monitoring of each zone can be achieved, avoiding the inaccurate temperature measurements caused by excessively large zone divisions in traditional methods. The combination of horizontal and vertical partitions results in a simple structure that is easy to install and maintain, and can accommodate battery packs of different sizes and shapes. Heat transfer between zones is minimal; the partitions reduce heat transfer and facilitate heat management.

[0050] Furthermore, in this embodiment, by M The location distribution of each red-temperature zone was obtained M-G+N The specific method for defining a red temperature zone is as follows: By numbering the horizontal and vertical partitions sequentially, we obtain the number... i The transverse partition and the first Between the transverse partitions, the first j Vertical partition and the first j+1 The smallest quadrilateral enclosed by the vertical partitions is numbered as follows: By M By comparing the numbers of the red-temperature communities, we can obtain... N A red-temperature series region with at least one overlapping plate. N The red temperature series area is composed of G Several red-temperature zones were formed, and the calculated red-temperature region formed after recombination was [value missing]. M-G+N This method, through numbering and combination calculations, can automatically and quickly identify the location and range of the red-temperature zone, reducing errors from manual judgment and improving identification efficiency. It can also dynamically adjust the division of the red-temperature zone based on real-time temperature data, adapting to temperature changes in the battery pack under different operating conditions and ensuring the real-time performance and accuracy of the heat dissipation strategy.

[0051] See Figure 1 The five red-temperature residential areas are numbered as follows: ; Among them, three red-temperature communities Adjacent to each other, the three have overlapping transverse partitions. and vertical partition Two red-temperature communities Adjacent to each other, with overlapping vertical partitions between them. .

[0052] Furthermore, in this embodiment, by comparison M-G+N The method for identifying the most severely overheated red-temperature zone by measuring the heat level of each zone is as follows: pass M The temperature of each red-temperature zone is obtained from the temperature of each red-temperature cell, and the simulated heat of each red-temperature zone is calculated. H By comparing the simulated heat in each red temperature region H The size of the simulated heat is used to identify the most severely heated red-temperature region. Finally, overlapping horizontal or vertical partitions within this region are removed to obtain the region's number; the simulated heat... .

[0053] like Figure 1 As shown, three red-temperature communities The combined red temperature zone The area is 3m 2 The average temperature is 150 degrees Celsius, and there are two red-temperature zones. The combined red temperature zone The area is 2m 2 If the average temperature is 200 degrees Celsius, then the red-temperature area formed by the combination of three red-temperature zones is considered to be the red-temperature area with the most severe heat generation. Therefore, the overlapping diaphragms... Vertical partition Extracting the red temperature region reveals a connected region.

[0054] in, S The area of ​​the red-temperature region, T This refers to the temperature of the red-temperature zone. By comparing the heat levels in each zone, the area with the most severe overheating can be accurately located, providing a precise target area for subsequent targeted heat dissipation.

[0055] In this embodiment, after identifying the red temperature area with the most severe current overheating, the first... i Temperature of each temperature zone T i Compare with a preset second temperature threshold to filter out F A supercooled region, by... F The numbers of the subcooled areas are compared with the numbers of the red-temperature areas with the most severe overheating. The final heat dissipation area is obtained by combining adjacent overlapping partitions, where the second temperature threshold is lower than the first temperature threshold. By introducing the second temperature threshold, subcooled areas can be screened out. By combining the subcooled areas with the red-temperature areas with the most severe overheating, the subcooled areas can be heated to a certain extent, effectively protecting the lifespan of the device.

[0056] In this embodiment, the simulated position of the fan is calculated based on the location and temperature value of the final heat dissipation area. , The specific formula is as follows:

[0057]

[0058] in,( , ) is the first i Location coordinates of the Hongwen residential area; The final position of the fan is obtained based on the simulated position of the fan.

[0059] In this embodiment, the heat dissipation zone corresponding to the red temperature zone is obtained by identifying the location of the red temperature zone with the most severe heat generation. The final position of the fan is obtained based on the optimal position of the fan. Specifically, the simulated position of the fan ( , The fan's final location is determined by comparing it with the location of the nearest heat dissipation zone. By selecting the nearest heat dissipation zone as the fan's final location, the heat dissipation path can be shortened to the maximum extent, reducing energy loss during heat transfer and thus optimizing the allocation and utilization efficiency of heat dissipation resources.

[0060] The method disclosed in this invention divides the battery pack into multiple temperature zones and monitors the temperature of each zone in real time, enabling precise location of abnormal heat points and avoiding the lag problem of traditional overall temperature control methods. This method employs a graded temperature comparison strategy, first screening out red-temperature zones, then intelligently identifying red-temperature series regions based on planar distribution relationships, and finally pinpointing the most severe heat-generating area through comprehensive thermal assessment. This progressive diagnostic mechanism significantly improves the accuracy and efficiency of thermal fault location, and is particularly suitable for multi-point thermal runaway early warning in high-energy-density battery packs.

[0061] This embodiment also discloses an energy storage thermal management and control system, including: The temperature zone division module is used to divide the battery pack into temperature zones and obtain the real-time temperature of each temperature zone. The red temperature zone division module is used to compare the real-time temperature of each temperature zone with a preset first temperature threshold and filter out red temperature zones whose real-time temperature is higher than the first temperature threshold. The red temperature zone determination module is used to merge adjacent red temperature cells into a red temperature series region based on the location distribution of red temperature cells, and to form multiple red temperature regions based on the merging results. The module for determining the highest red temperature zone is used to compare the heat of each red temperature zone and determine the red temperature zone with the highest current temperature. The optimal fan position determination module is used to calculate the optimal position of the fan on the preset guide rail based on the position and temperature value of the red temperature zone with the highest current temperature.
