Description

Technical Field

[0001] The present invention relates to the field of temperature control technology, and in particular to a heat dissipation method for a power exchange cabinet, a power exchange cabinet, an electronic device and a computer-readable storage medium. Background Art

[0002] In recent years, with the enhancement of environmental awareness and the acceleration of urbanization, electric bicycles have been widely popularized in China as a green and convenient means of transportation. According to statistics, the number of electric bicycles in China has reached 350 million. With the rapid development of the food delivery and express delivery industries, among the huge user groups of electric bicycles, there are nearly 20 million food delivery and express delivery practitioners. These users have an urgent need for fast charging, especially in the case of limited living conditions, insufficient charging facilities and safety considerations. Battery swap cabinets have become an ideal solution.

[0003] The working principle of the battery swap cabinet is to quickly replenish the vehicle's energy by quickly replacing the battery on the electric bicycle without having to wait for a long time for charging to be completed. Heat will inevitably be generated during the battery charging process of the battery swap cabinet. If the heat is allowed to accumulate in the battery swap compartment and the temperature of the battery swap compartment continues to rise, it will not only affect the charging efficiency of the battery, but may also cause charging failures due to high temperature. Therefore, the heat dissipation of the battery swap cabinet is extremely important. Common battery swap cabinets mainly rely on fan heat dissipation - by configuring one or more fans for each battery swap compartment, and controlling the start and stop of the corresponding fans according to the temperature of the battery swap compartment, thereby achieving heat dissipation of the battery swap compartment. Although this heat dissipation method can achieve heat dissipation, configuring a fan for each battery swap compartment separately is not only complex in structure and high in manufacturing cost, but also requires a large number of fans to consume more electricity, resulting in high operating costs. In addition, a large number of fans are arranged in a scattered manner, which is not conducive to later maintenance.

[0004] Therefore, how to reduce the heat dissipation energy consumption of the battery swap cabinet is a technical problem that technicians currently need to solve. Summary of the invention

[0009] In combination with the power exchange cabinet heat dissipation method provided in the first aspect, the first possible heat dissipation method of the power exchange cabinet in the first aspect, or the second possible heat dissipation method in the first aspect, in the fourth possible heat dissipation method in the first aspect, S3 and subsequent steps further include: S51: Determine whether a signal to open the door is received; S52: If yes, obtain the external environment temperature T3, and compare T1 and T3; S53: If T1>T3, the door is controlled to be unlocked and the air suction efficiency is increased after the door is opened; if T1≤T3, the door is controlled to be unlocked and the air supply efficiency is increased.

[0010] In combination with the third possible heat dissipation method for the power swap cabinet of the first aspect, in a fourth possible heat dissipation method for the power swap cabinet of the first aspect, S53 includes: S531: Control the second air vent A to open, where the second air vent A is the second air vent opposite to the door; S532: If T1>T3, the door is controlled to be unlocked and the air suction efficiency is increased after the door is opened; if T1≤T3, the door is controlled to be unlocked and the air supply efficiency is increased.

[0011] In combination with the power exchange cabinet heat dissipation method provided in the first aspect, the first possible heat dissipation method of the power exchange cabinet in the first aspect, or the second possible heat dissipation method in the first aspect, in the fifth possible heat dissipation method in the first aspect, S3 and subsequent steps further include: S61: Detect whether there is a battery swap compartment A, where the battery swap compartment A is a battery swap compartment with a compartment door in an open state; S62: If yes, obtain the external environment temperature T3, and compare T1A, T1B and T3. Battery swap compartment B is the battery swap compartment adjacent to battery swap compartment A. T1A is T1 of battery swap compartment A, and T1B is T1 of battery swap compartment B.

[0016] It can be seen from the above technical solutions that the present invention has the following advantages: The heat dissipation method for the battery swap cabinet provided by the present invention connects all the battery swap compartments with one or a few radiators through a heat dissipation channel. Only when the temperature of a battery swap compartment exceeds a preset threshold, the corresponding second air outlet is controlled to open, so that the battery swap compartment that needs heat dissipation is connected to the heat dissipation channel, and the radiator is started to accurately dissipate the heat of the corresponding battery swap compartment. Compared with the traditional heat dissipation method, a heat dissipation device is separately configured for each battery swap compartment, the number of radiators is reduced, energy consumption is reduced, and thus the heat dissipation energy consumption of the battery swap cabinet is reduced.

[0017] At the same time, by sharing the heat dissipation channel, the radiator can centrally handle the heat dissipation needs of multiple battery swap compartments instead of dispersing them. This means that the heat dissipation resources are used more efficiently, responding to temperature changes more quickly and improving heat dissipation efficiency.

[0018] In addition, the centralized heat dissipation design allows the system to better control the heat dissipation process, avoiding the problem of premature aging or failure of heat dissipation equipment that may occur in traditional methods. At the same time, due to the existence of heat dissipation channels, the heat dissipation strategy can be adjusted more flexibly to improve the reliability and stability of the entire system.

[0022] The embodiments of the present invention provide a power exchange cabinet heat dissipation method, a power exchange cabinet, an electronic device and a computer-readable storage medium, which are used to solve the technical problem that the power exchange cabinet has high heat dissipation energy consumption in the prior art.

[0023] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In the description of the embodiments of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0025] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a replaceable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0026] The working principle of the battery swap cabinet is to quickly replenish the vehicle's energy by quickly replacing the battery on the electric bicycle without having to wait for a long time for charging to be completed. Heat will inevitably be generated during the battery charging process of the battery swap cabinet. If the heat is allowed to accumulate in the battery swap compartment and the temperature of the battery swap compartment continues to rise, it will not only affect the charging efficiency of the battery, but may also cause charging failures due to high temperature. Therefore, the heat dissipation of the battery swap cabinet is extremely important. Common battery swap cabinets mainly rely on fan heat dissipation - by configuring one or more fans for each battery swap compartment, and controlling the start and stop of the corresponding fans according to the temperature of the battery swap compartment, thereby achieving heat dissipation of the battery swap compartment. Although this heat dissipation method can achieve heat dissipation, configuring a fan for each battery swap compartment separately is not only complex in structure and high in manufacturing cost, but also requires a large number of fans to consume more electricity, resulting in high operating costs. In addition, a large number of fans are arranged in a scattered manner, which is not conducive to later maintenance. Example

[0027] See also Figure 1 , a heat dissipation method for a power exchange cabinet provided by an embodiment of the present invention includes: S1: Obtain the temperature T1 of N battery swap compartments in real time, where N is an integer greater than or equal to 2; Specifically, there are usually multiple battery swapping compartments inside the battery swapping cabinet, and each battery swapping compartment needs to monitor the temperature independently. Through the temperature sensor installed inside each battery swapping compartment, the system can monitor the temperature T1 of each battery swapping compartment in real time. For example, if a battery swapping cabinet contains 10 battery swapping compartments, then N=10, and the system will collect the temperature data of each battery swapping compartment at a regular interval (such as once a minute).

[0028] S2: Compare N T1s with the temperature threshold T2 respectively to determine whether there is T11, and T11 is T1 greater than T2; Specifically, a temperature threshold T2 is set as the warning standard, for example, T2 = 40°C. When the temperature T1 of any battery swap compartment exceeds this threshold, the system will determine that the battery swap compartment is at risk of overheating. Here, T11 refers to the temperature value of the battery swap compartment whose temperature exceeds the threshold.

[0029] The optimal operating temperature range of the battery is usually between 20°C and 25°C. Beyond this range, especially in high temperature environments, the chemical reaction rate of the battery will accelerate, which may cause problems such as electrolyte evaporation and diaphragm shrinkage inside the battery, thereby affecting the life and performance of the battery. Therefore, the temperature threshold T2 needs to be set within a temperature range that will not have a negative impact on the battery. It is usually recommended not to exceed 40°C to ensure that the battery operates at a relatively safe temperature. The heat dissipation efficiency determines to a certain extent whether the battery swap cabinet can remove the generated heat in time. If the temperature of the battery swap warehouse is too high, it will not only affect the charging efficiency of the battery, but also increase the burden on the heat dissipation system. Excessive temperature will reduce the heat dissipation efficiency because the radiator takes longer to dissipate the heat, which in turn will lead to more heat accumulation, forming a vicious circle. Taking the above factors into account, the temperature threshold T2 can be set at around 40°C. This value is an empirical value, because in most cases, when the temperature exceeds 40°C, the performance of the battery will be significantly affected, and the heat dissipation efficiency will also decrease.

[0030] S3: If it exists, the radiator corresponding to the first air outlet of the heat dissipation channel is controlled to start, and the second air outlet of the battery swap compartment corresponding to T11 is controlled to open. The second air outlet is used to connect the battery swap compartment with the heat dissipation channel.

[0031] Specifically, once it is found that the temperature T1 of a battery swap compartment exceeds the preset temperature threshold T2, the system will automatically activate the radiator (such as a cooling fan or a heat sink) connected to the heat dissipation channel, and open the second air outlet corresponding to the battery swap compartment to connect the battery swap compartment with the heat dissipation channel, so that the hot air in the battery swap compartment can be discharged through the heat dissipation channel, thereby achieving heat dissipation. It should be noted that the heat dissipation channel can have multiple second air outlets and one first air outlet, and each battery swap compartment has the same number of second air outlets, and then they are all connected to the radiator through the same first air outlet; it can also have the same number of second air outlets and first air outlets, and each second air outlet is connected to a corresponding first air outlet; it can also be a first air outlet connected to one or more second air outlets opened in the same battery swap compartment. In these three types of heat dissipation channels, the first air outlet needs to be set in the same area of ​​the battery swap cabinet. By setting the radiator at a position opposite to the first air outlet and making the input or output end of the radiator opposite to the first air outlet, efficient heat dissipation of the battery swap cabinet can be achieved through radiators less than the number of battery swap compartments. The beneficial effects of this embodiment include: ① The heat dissipation method for the battery swap cabinet provided by the present invention connects all the battery swap compartments with one or a few radiators through a heat dissipation channel. Only when the temperature of a battery swap compartment exceeds a preset threshold, the corresponding second air outlet is controlled to open, so that the battery swap compartment that needs heat dissipation is connected to the heat dissipation channel, and the radiator is started to accurately dissipate the heat of the corresponding battery swap compartment. Compared with the traditional heat dissipation method, a heat dissipation device is separately configured for each battery swap compartment, the number of radiators is reduced, energy consumption is reduced, and thus the heat dissipation energy consumption of the battery swap cabinet is reduced.

[0032] ② By sharing the heat dissipation channel, the radiator can centrally handle the heat dissipation needs of multiple battery swap compartments instead of dispersing them. This means that the heat dissipation resources are used more efficiently, can respond to temperature changes more quickly, and improve heat dissipation efficiency.

[0033] ③The centralized heat dissipation design enables the system to better control the heat dissipation process, avoiding the problem of premature aging or failure of heat dissipation equipment that may occur in traditional methods. At the same time, due to the existence of heat dissipation channels, the heat dissipation strategy can be adjusted more flexibly to improve the reliability and stability of the entire system.

[0034] ④ There is no need to configure a heat dissipation device for each battery swap compartment, which reduces the number of devices and simplifies the internal structure of the battery swap cabinet. This not only reduces manufacturing costs, but also simplifies maintenance work because only a few radiators need to be maintained.

[0035] ⑤ As the number of radiators is reduced and they work through a unified heat dissipation channel, maintenance becomes simpler. Once a radiator fails, only a small amount of equipment needs to be repaired or replaced, without having to check and maintain them one by one.

[0036] Optimize the above basic power exchange cabinet heat dissipation method: add a temperature change rate monitoring mechanism, the specific steps are as follows: Optimize S1 to: S11: Obtain M consecutive times T1 of the same battery swap compartment, where M is an integer greater than or equal to 2; Specifically, the system not only needs to monitor the current temperature of each battery swap compartment, but also needs to record the temperature change history over a continuous period of time (for example, once per minute). For example, for a specific battery swap compartment, the system records temperature data points for two consecutive minutes, that is, M=2. Assume that the temperature at the first time point is T1a=35℃, and the temperature at the second time point is T1b=38℃.

[0037] S12: Calculate the temperature change rate S1 of the corresponding battery swap compartment according to the M T1s to obtain N S1s; Specifically, these two temperature data are used to calculate the temperature change trend of the battery swap compartment. If the temperature rises very quickly in a short period of time, then even if the current temperature has not reached the threshold, it may indicate that overheating is about to occur. For example, the temperature change rate is S1 = (T1a-T1b) / time interval = (38-35) / 1 = 3 ° C / min. If there are 10 battery swap compartments in the system, 10 temperature change rates S1 will be obtained.

[0038] Accordingly, S2 is optimized as follows: N T1s are compared with the temperature threshold T2 to determine whether T11 exists, N S1s are compared with the temperature change rate threshold S2 to determine whether S11 exists, T11 is T1 greater than T2, and S11 is S1 greater than S2; Specifically, an additional step is added on the basis of the above step S2: set a temperature change rate threshold S2, for example, S2=2℃ / min. If the temperature change rate of a battery swap compartment exceeds this threshold, it is considered that the battery swap compartment may have a potential overheating risk. In the above example, it is calculated that S1=3℃ / min>S2=2℃ / min, so S11=S1.

[0039] Correspondingly, step S3 is optimized as follows: if it exists, the radiator corresponding to the first air outlet of the heat dissipation channel is controlled to start, and the second air outlet of the battery swap compartment corresponding to S11 and / or T11 is controlled to open, and the second air outlet is used to connect the battery swap compartment with the heat dissipation channel.

[0040] Specifically, if it is found that the temperature change rate exceeds the standard or the temperature itself exceeds the threshold, heat dissipation measures are taken - open the second air outlet of the corresponding battery swap cabinet and start the radiator for heat dissipation. When the temperature change rate exceeds the preset threshold, the system can respond immediately, start the radiator and open the second air outlet of the relevant battery swap compartment to dissipate the heat faster. By monitoring the temperature change rate, the risk of overheating can be identified before the temperature reaches the dangerous threshold, so that heat dissipation measures can be started in advance to avoid further temperature increases. The temperature change rate monitoring mechanism enables the system to not only pay attention to the temperature itself, but also to evaluate the rate of temperature rise, which helps prevent overheating.

[0041] Optimization of the above basic power exchange cabinet heat dissipation method: Add consideration of the external ambient temperature change rate and further optimize the heat dissipation strategy - add the following steps after step S3: S41: Obtain the temperature change rate of the external environment S3; Specifically, it is necessary to monitor the temperature change rate S3 of the external environment. This can be achieved by installing a sensor outside the power exchange cabinet to continuously collect external environment temperature data and calculate the temperature change rate over a period of time. Assume that the temperature change rate of the external environment is S3 = -2 ° C / min (that is, the ambient temperature is decreasing).

[0042] S42: Calculate the difference SC between S1 and S3; Specifically, for each battery swap compartment temperature change rate S1, calculate the difference SC between it and the external environment temperature change rate S3. This step helps to understand the relationship between the internal temperature change of the battery swap compartment and the external environment. In the above example, we got S1=3℃ / min, and now calculate SC=S1-S3=3-(-2)=5℃ / min.

[0043] S43: Control the heat dissipation rate of the radiator according to SC.

[0044] Specifically, if SC is positive, it means that the temperature change rate in the battery swap warehouse is faster than the external environment, and heat dissipation may need to be strengthened; if SC is negative, it means that the change in external environmental temperature may have a positive impact on the internal temperature of the battery swap warehouse, and the operating intensity of the radiator can be moderately reduced or kept unchanged. Assume that the set temperature difference threshold is SC1=4℃ / min. Since SC=5℃ / min>SC1=4℃ / min, the system will increase the heat dissipation rate of the radiator to reduce the temperature in the battery swap warehouse more quickly. The introduction of the external ambient temperature change rate can help the system more accurately judge when heat dissipation needs to be strengthened and when the heat dissipation power can be reduced, thereby further optimizing energy consumption. Taking into account the impact of the external environment, the heat dissipation strategy can be made more reasonable, avoiding system instability caused by sudden changes in the external environment, and making heat dissipation more intelligent and adaptable.

[0045] Further optimization of the heat dissipation method of the power exchange cabinet: Based on the above, a heat dissipation logic related to the operation of the compartment door is added, as follows: S51: Determine whether a signal to open the door is received; Specifically, assuming that a user is requesting to open the door of a battery swap compartment, a signal to open the door will be received at this time.

[0046] S52: If yes, obtain the external environment temperature T3, and compare T1 with T3; Specifically, when it is determined that the door opening signal is received, the temperature of the external environment is obtained and compared with the temperature inside the battery swap compartment. Assuming that the external environment temperature is T3 = 25°C and the temperature inside the battery swap compartment is T1 = 38°C, the two temperatures are compared.

[0047] S53: If T1>T3, the door is controlled to be unlocked and the air suction efficiency is increased after the door is opened; if T1≤T3, the door is controlled to be unlocked and the air supply efficiency is increased.

[0048] Specifically, when T1>T3, that is, the temperature inside the warehouse is higher than the external environment temperature, the battery swap warehouse can be quickly cooled by inhaling low-temperature air from the external environment. Therefore, after receiving the signal to open the warehouse door, the system will control the door to unlock, and increase the suction efficiency after the door is opened to help reduce the temperature inside the warehouse; when T1≤T3, the temperature inside the warehouse is lower than the external environment temperature, in order to reduce the amount of hot air from the external environment flowing into the battery swap warehouse, the blowing efficiency is increased. Before the user opens the door, the system can adjust the cooling mode according to the temperature difference between the inside and outside, and adjust the cooling strategy according to the temperature difference between the inside and outside, which can save more energy and avoid unnecessary energy waste.

[0049] Further refinement of step S53 specifically includes the following steps: S531: Control the second air vent A to open, where the second air vent A is the second air vent opposite to the door; Specifically, before controlling the door to be unlocked, the second air vent A opposite to the door is controlled to be opened. Opening the second air vent A opposite to the door helps to form a better air circulation path and improve the heat dissipation efficiency.

[0050] S532: If T1>T3, the door is controlled to be unlocked and the air suction efficiency is increased after the door is opened; if T1≤T3, the door is controlled to be unlocked and the air supply efficiency is increased.

[0051] Specifically, after adding step S531, because the opened second air outlet is opposite to the warehouse door, when T1≤T3, the wind blown out of the second air outlet can push the unlocked warehouse door to rotate outward, and the warehouse door can be automatically opened. When T1>T3, when the user closes the warehouse door, a certain suction force can be formed on the warehouse door, thereby reducing the resistance of the warehouse door closing, and at the same time avoiding the rebound of the warehouse door, improving the comfort of use. In addition, by dynamically adjusting the suction or air supply efficiency, the heat dissipation strategy can be adjusted according to actual needs, reducing the impact of the external environment on the temperature rise of the battery swap warehouse, and increasing the impact of the external environment on the temperature drop of the battery swap warehouse, so as to achieve the best temperature control effect.

[0052] The above heat dissipation method for the battery swap cabinet adopts a control strategy of separate heat dissipation for each battery swap compartment. The following introduces a control management mechanism for temperature interaction between battery swap compartments to further optimize the heat dissipation method for the battery swap cabinet. Specifically, the following steps are added after step S3. Of course, the following steps can also be combined with step S4 (S41-S43) and step S5 (S51-S53) respectively, or combined with step S4 and step S5 at the same time to form a technical solution.

[0053] S 61: Detect whether there is a battery swap compartment A, where the battery swap compartment A is a battery swap compartment with a compartment door in an open state; Specifically, when it is detected that the door of a battery swap compartment is in an open state, the battery swap compartment is battery swap compartment A.

[0054] S62: If yes, obtain the external environment temperature T3, and compare T1A, T1B and T3. Battery swap compartment B is the battery swap compartment adjacent to battery swap compartment A. T1A is T1 of battery swap compartment A, and T1B is T1 of battery swap compartment B. Specifically, the battery swap compartments of the battery swap cabinet are usually arranged in a matrix, so the battery swap compartments at the corner positions have 2 adjacent battery swap compartments, the battery swap compartments at the edge positions have 3 adjacent battery swap compartments, and the battery swap compartments at other positions have 4 adjacent battery swap compartments. Battery swap compartment B is the battery swap compartment adjacent to battery swap compartment A. The external environment temperature T3 is obtained, and the obtained temperature T1A of battery swap compartment A, the temperature T1B of multiple battery swap compartments B and the external environment temperature T3 are compared. Assume that the temperature T1A of battery swap compartment A is 38°C, the temperatures of the two battery swap compartments B are the same, both T1B=40°C, and the external environment temperature T3=25°C.

[0055] S63: If T1B>T1A≥T3, control to open the third air vent, the third air vent is used to connect the battery swap compartment B with the battery swap compartment A; Specifically, when T1B>T1A≥T3, that is, the temperature of battery swap compartment B is higher than that of battery swap compartment A, and the temperature of battery swap compartment A is higher than or equal to the temperature of the external environment, and at this time the battery swap compartment A is in a door-open state, it can quickly exchange air with the outside world to achieve rapid cooling, so the third air vent in the battery swap compartment that is connected to battery swap compartment B is controlled to open. In this way, the heat of battery swap compartment B can be transferred to battery swap compartment A through the third air vent, and then discharged to the external environment; the low-temperature air in the external environment can also be sucked into battery swap compartment B through battery swap compartment A and through the third air vent to replace the high-temperature air in battery swap compartment B, thereby achieving rapid cooling of battery swap compartment B. It should be noted that when T1B<T1A≤T3 or T1B>T1A<T3, it means that the temperature of battery swap compartment A is higher than that of battery swap compartment B, or the temperature of the external environment is higher than that of battery swap compartment B, so there is no need to open the third air vent to prevent the high-temperature air of battery swap compartment A and the external environment from entering battery swap compartment B and heating up battery swap compartment B. When T1B<T1A>T3, it means that the temperature of battery swap compartment A is the highest, so first let battery swap compartment A complete heat exchange with the external environment, and then control to open the third air vent after the temperatures of the two are equal, or until the temperature of battery swap compartment A is lower than that of battery swap compartment B. In addition, a second air vent opposite to the third air vent can also be opened to further improve the heat dissipation efficiency. It should be understood that the second air vent opposite to the compartment door is opened in battery swap compartment A at this time, and the second air vent opposite to the third air vent is opened in battery swap compartment B.

[0056] S64: Controls the radiator to increase the heat dissipation rate.

[0057] Specifically, in order to further improve the heat exchange efficiency between battery swap compartment B and the external environment through battery swap compartment A, and to further improve the heat dissipation efficiency, the radiator is controlled to increase the heat dissipation rate, that is, to speed up the efficiency of blowing the high-temperature air in battery swap compartment B to battery swap compartment A and blowing the air in battery swap compartment A to the external environment, or to speed up the efficiency of sucking the low-temperature air in battery swap compartment A into battery swap compartment A and the low-temperature air in the external environment into battery swap compartment A. By opening the vents between the two battery swap compartments, the heat is evenly distributed between different battery swap compartments, and rapid heat exchange with the external environment is achieved, which improves the heat dissipation efficiency. While the efficiency is improved, the energy consumption of heat dissipation is also reduced.

[0058] The above heat dissipation method for the battery swap cabinet is only for dissipating the heat of the internal battery under normal charging conditions of the battery swap compartment. In order to further improve the heat dissipation method of the battery swap cabinet, the following provides a heat dissipation method for abnormal charging conditions, specifically adding the following steps after step S3. Of course, the following steps can also be combined with step S4 (S41-S43) and step S5 (S51-S53) and step S6 (S61-S64) respectively, or combined with step S4, step S5 and step S6 at the same time to form a technical solution.

[0059] S71: Compare T1 with the temperature threshold T4, compare S1 with the temperature change rate S4, determine whether T14 and S14 exist at the same battery swap compartment, T12 is T1 greater than T4, S14 is S1 greater than S4, T4>T2, S4>S3; Specifically, two new thresholds are defined here: T4 and S4. T4 is a temperature threshold higher than T2, while S4 is a temperature change rate threshold higher than S3. These two thresholds are set to more strictly monitor the temperature and its changes in the battery swap compartment to determine whether there is a more serious risk of overheating or charging failure. T4 is a threshold higher than the upper limit of the normal operating temperature, which is used to determine whether there is a more serious risk of overheating. Normally, the optimal operating temperature range of the battery is between 20°C and 25°C, and T2 (for example, 40°C) is already a higher warning temperature. T4 is set at a higher temperature value, such as 45°C, to ensure that timely measures can be taken in extreme cases. S4 is a threshold higher than the normal temperature change rate, which is used to determine whether there is a sharp rise in temperature, which may be a manifestation of internal battery failure or charging system failure. For example, if S3 is set to 2°C / min, then S4 can be set to 3°C / min to ensure timely response when the temperature change rate increases abnormally. As higher thresholds, T4 and S4 can provide early warning functions. When the temperature or temperature change rate exceeds these thresholds, it means that there may be a more serious risk of overheating or potential charging failure in the battery swap compartment. Higher thresholds can help the system detect possible failures earlier, so that timely measures can be taken to avoid more serious consequences.

[0060] S72: If so, calculate the difference TC between T141 and T14, where T141 is T1 of the battery swap compartment whose charging condition is closest to the charging condition of the battery swap compartment corresponding to T14; Specifically, if it is found that the temperature of the same battery swap warehouse exceeds T4 and its temperature change rate exceeds S4, then find a battery swap warehouse with a charging condition most similar to that of the battery swap warehouse, and calculate the temperature difference TC between the two battery swap warehouses. The closest charging condition means that the charging time, charging speed and remaining power of the battery in the battery swap warehouse are relatively close. By finding the battery swap warehouse with the closest charging condition, it can be ensured that the comparison basis is consistent. This means that under the same charging conditions, if the temperature difference is too large, it may mean that there is a problem with the current battery swap warehouse, which can help the system locate potential fault locations and take timely measures.

[0061] S73: Compare TC with temperature difference threshold TC1; Specifically, a temperature difference threshold TC1 is set to determine whether the temperature difference between the current battery swap compartment and the battery swap compartment under similar charging conditions is too large. As a temperature difference threshold, TC1 can help the system more accurately determine whether the current temperature of the battery swap compartment is abnormal. If the temperature difference exceeds this threshold, it indicates that there is a potential problem. Setting TC1 can avoid misjudging a fault due to slight temperature fluctuations and ensure the accuracy of the system.

[0062] S74: If TC>TC1, the corresponding battery swap compartment is powered off and the heat dissipation rate of the radiator is increased.

[0063] Specifically, if the temperature difference TC exceeds the temperature difference threshold TC1, it means that the temperature of the current battery swap compartment and its rate of change have exceeded the predetermined threshold, and compared with another battery swap compartment in a similar charging state, the temperature difference is large, that is, the temperature is abnormally high, and there is a potential risk of charging failure or overheating. Measures need to be taken in time to reduce the temperature to prevent safety problems caused by overheating. Therefore, the corresponding battery swap compartment is powered off and the heat dissipation rate of the radiator is increased. Power off can prevent the battery from continuing to charge at high temperatures, thereby protecting the battery from damage. Increasing the heat dissipation rate can dissipate heat faster to reduce the temperature as soon as possible. Through intelligent decision-making, charging can be stopped intelligently in extreme cases, which can effectively avoid equipment damage caused by excessive temperature or safety accidents caused by overheating, thereby enhancing safety. Example

[0064] An embodiment of the present invention provides a power exchange cabinet that adopts any of the power exchange cabinet heat dissipation methods provided in Embodiment 1.

[0065] Specifically, a heat dissipation channel is designed inside the battery swap cabinet, and the heat dissipation channel connects all the battery swap compartments with one or more shared radiators. This means that heat dissipation is not achieved by separately configuring a heat dissipation device for each battery swap compartment, but is achieved through a shared radiator and a heat dissipation channel. The battery swap cabinet also integrates an intelligent temperature control system, which can monitor the temperature of each battery swap compartment in real time, and decide whether to start the radiator and how to adjust the heat dissipation rate based on the actual temperature and temperature change rate, that is, the power swap cabinet heat dissipation method of embodiment 1 is used to dissipate heat for the power swap cabinet.
