Description

Technical Field

[0001] The present invention relates to the field of battery processing technology, and in particular to a high-temperature stabilization method, system, medium and equipment for electrolyte in a solid-state battery. Background Art

[0002] Solid-state batteries are a type of battery technology that uses solid electrolytes instead of liquid or gel electrolytes. Compared with traditional liquid batteries (such as lithium-ion batteries), solid-state batteries have many potential advantages, including higher safety, longer service life, and higher energy density. Therefore, they have received widespread attention in the fields of electric vehicles, portable electronic devices, and energy storage systems.

[0003] Solid-state batteries work similarly to conventional lithium-ion batteries, but their electrolytes are different. In solid-state batteries, ions are transported between the positive and negative electrodes through a solid electrolyte rather than a liquid or gel electrolyte.

[0004] The ionic conductivity of the electrolyte is one of the key indicators of solid-state battery performance. Temperature changes have a significant impact on the ionic conductivity of the electrolyte. During the use of solid-state batteries, in the low to medium temperature range (usually 25°C to 60°C), the ionic conductivity of the electrolyte usually increases with increasing temperature.

[0005] When the temperature increases, the thermal energy of the ions in the electrolyte increases, making it easier for the ions to overcome the lattice resistance or the ion migration energy barrier of the electrolyte, thereby increasing the migration rate of the ions.

[0006] As the temperature increases, the migration of ions in the electrolyte becomes more active, especially for materials with high ionic conductivity (such as lithium aluminum zirconium oxide LLZO, sulfides, etc.), the effect of temperature on improving ionic conductivity is more significant.

[0007] However, when the temperature rises to a certain extent (such as over 60°C or higher), the stability of the electrolyte material may be threatened as the temperature further increases. For example, some oxide electrolytes (such as LLZO) may undergo phase transition or structural degradation at high temperatures, while sulfide electrolytes (such as Li10GeP2S12) easily react with moisture in the air at high temperatures, resulting in a decrease in electrolyte performance.

[0008] Changes in temperature may cause thermal expansion or contraction of the electrolyte inside the battery, resulting in changes in the microstructure of the electrolyte material and even cracks or delamination, affecting ionic conductivity.

[0009] Especially when solid-state batteries are used to drive cars, as the car runs for a long time, the electrolyte in the solid-state battery will be discharged for a long time and the high temperature will be released, which will cause the internal temperature of the solid-state battery to rise sharply. When the heat cannot be discharged, the solid-state battery is very likely to spontaneously combust, resulting in fires and causing personal accidents.

[0010] The existing method of cooling solid-state batteries is to use liquid cooling, but liquid cooling has the following problems: the temperature of the electrolyte near the outside of the solid-state battery drops faster than the temperature in the center, resulting in a large temperature difference in the electrolyte of the solid-state battery, making the cooling effect poor.

[0011] Secondly, during the use of solid-state batteries, if the fixed power is maintained for a long time to dissipate heat and cool the electrolyte of the fixed battery, the energy consumption of the fixed battery will increase, thereby reducing the battery life of the fixed battery.

[0079] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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.

[0080] The present invention provides a high temperature stabilization method for electrolyte in a solid-state battery, which is applied to a solid-state battery for an automobile, and the method comprises:

[0081] S101, periodically acquiring temperature data of a solid-state battery of a vehicle during operation to generate first temperature data;

[0082] S102, selecting a maximum temperature value from the first temperature data to obtain a maximum electrolyte temperature value;

[0083] S103, calculating the actual maximum temperature value of the electrolyte according to the maximum temperature value of the electrolyte and the compensation temperature threshold;

[0084] S104, comparing the actual maximum temperature value of the electrolyte with a preset temperature value;

[0085] S105. If the actual maximum temperature value of the electrolyte is greater than or equal to the preset temperature value, a first heat dissipation instruction is generated and executed to adjust the heat dissipation power of the radiator around the solid-state battery.

[0086] Please refer to Figure 1-Figure 3 In this embodiment, the system periodically obtains temperature data during the operation of the solid-state battery, and obtains and generates first temperature data.

[0087] The maximum temperature value is screened out from the first temperature data, indicating the hottest part in the battery, to obtain the maximum temperature value of the electrolyte.

[0088] The system calculates the actual maximum temperature of the electrolyte based on the maximum temperature of the electrolyte and the temperature threshold, and compares it with the preset temperature value.

[0089] If the actual maximum temperature value of the electrolyte exceeds the standard, a first heat dissipation instruction is generated and executed to adjust the radiator power to reduce the temperature.

[0090] Through precise temperature monitoring and dynamic heat dissipation adjustment, battery overheating can be effectively avoided, and the risks of spontaneous combustion, thermal runaway, etc. can be reduced. The safety of automotive solid-state battery systems can be significantly improved, and the electrolytes in solid-state batteries can be stable at high temperatures.

[0091] Dynamically adjust the cooling power and perform temperature control based on actual needs instead of maintaining a fixed cooling power for a long time, which helps save energy and improve overall system efficiency.

[0092] It should be noted that the system periodically collects temperature data during the operation of the solid-state battery through sensors or temperature detection devices to generate first temperature data, that is, temperature information at the current moment or within a period.

[0093] Regularly acquiring temperature data can provide real-time temperature information for subsequent temperature control adjustments, helping to promptly detect whether the battery has reached or exceeded a safe operating temperature range.

[0094] The system selects the maximum temperature value from the collected temperature data, which represents the hottest point of the solid-state battery in the current working cycle. Especially in high-power applications such as automobiles, the temperature of different parts of the battery may be different. By selecting the maximum temperature, the temperature extreme point inside or outside the battery can be determined.

[0095] By selecting the maximum temperature value, the system can accurately determine the hottest part of the battery, avoiding focusing only on the overall average temperature and ignoring local high temperature areas that may cause thermal runaway.

[0096] Based on the obtained maximum temperature value and the preset compensation temperature threshold (the upper limit of safe operating temperature when designing solid-state batteries), the actual maximum temperature value of the electrolyte is calculated, reflecting the temperature state of the battery during actual operation.

[0097] It enables the system to more accurately judge the operating temperature of the electrolyte, avoid overly conservative or overly aggressive judgments, and improve the flexibility and accuracy of the temperature control system.

[0098] The calculated actual maximum temperature of the electrolyte is compared with a preset temperature value. If the temperature of the battery exceeds the preset temperature value, the system will take appropriate heat dissipation measures to ensure the safety of the battery.

[0099] The preset temperature value is a manually set temperature value, and the preset compensation temperature threshold is a temperature value on a curve corresponding to the current temperature value obtained through the temperature curve of the solid-state battery.

[0100] If the actual maximum temperature of the electrolyte exceeds the preset temperature value, the system will generate a first cooling instruction to start cooling measures. These cooling measures may include adjusting the cooling power of the radiator to reduce the temperature of the battery.

[0101] Once it is determined that the temperature of the electrolyte is too high, the system will generate a "first heat dissipation instruction" as needed. The instruction will be transmitted to the radiator control system to adjust the power or switch status of the radiator and start the cooling process to reduce the operating temperature of the battery.

[0102] In at least one embodiment of the present application, the method further includes:

[0103] S106: If the actual maximum temperature value of the electrolyte is less than the preset temperature value, perform the next cycle of detection.

[0104] Please refer to Figure 1-Figure 3In this embodiment, the actual maximum temperature value of the electrolyte is compared with the preset temperature value. If the battery temperature is normal (i.e., the actual maximum temperature value of the electrolyte is less than the preset temperature value), the system will skip any heat dissipation operation and enter the next cycle for temperature monitoring.

[0105] Excessive energy waste can be avoided by determining whether to activate the heat dissipation system based on the actual maximum temperature of the electrolyte. The system will only perform heat dissipation operations when the actual maximum temperature of the electrolyte exceeds the preset temperature value, so that the battery management system will not consume unnecessary energy during normal operation.

[0106] Not performing unnecessary cooling operations can reduce temperature fluctuations inside the battery and avoid thermal stress caused by excessive heat dissipation, which may help extend the battery's service life.

[0107] In at least one embodiment of the present application, the method further includes:

[0108] S201, obtaining the speed of the vehicle and generating a first speed;

[0109] S202, calculating the air flow velocity of the vehicle according to the first velocity to generate a first flow velocity;

[0110] S203, calculating a first theoretical temperature reduction value for air flow temperature reduction per unit time according to the first flow rate;

[0111] S204: Generate a second heat dissipation instruction according to the first theoretical temperature drop value and the actual maximum temperature value of the electrolyte, and adjust the heat dissipation power of the radiator according to the second heat dissipation instruction.

[0112] Please refer to Figure 1-Figure 3 In this embodiment, the system first obtains the current speed of the vehicle. This is usually obtained through the vehicle speed sensor (such as a wheel speed meter, GPS module, etc.) of the vehicle to generate a first flow rate. Since the vehicle speed is variable, this is the average vehicle speed in this cycle.

[0113] According to the first speed obtained, the air velocity around the car can be calculated. There is a certain relationship between the vehicle speed and the air velocity. Generally, the faster the vehicle speed, the greater the air velocity and the better the heat dissipation effect.

[0114] Through the principles of fluid mechanics or empirical models, the system calculates the first flow velocity based on the vehicle speed, that is, the speed at which the air flows around the vehicle body when the vehicle is moving.

[0115] Based on the calculated air flow rate (first flow rate), the system further calculates the first theoretical cooling value of the solid-state battery cooling caused by air flow. Taking into account factors such as air flow rate, radiator surface area, and ambient temperature, the theoretical value of the battery temperature reduction caused by air flow rate is given.

[0116] After obtaining the theoretical cooling value, the system will generate a second cooling instruction based on the actual maximum temperature of the electrolyte (i.e. the operating temperature of the battery). This instruction determines whether the cooling system needs to be started and how to adjust the cooling power to ensure that the battery temperature remains within a safe range.

[0117] The second cooling command is generated by dynamically adjusting the cooling strategy based on the vehicle speed and theoretical cooling capacity. If the theoretical cooling value is sufficient, the system can reduce the cooling power, otherwise it will increase the cooling power.

[0118] Through intelligent calculations based on real-time vehicle speed, air flow rate and battery temperature, the system can dynamically adjust the heat dissipation power to ensure that the battery is cooled most appropriately in different working environments.

[0119] Avoid over-activating the radiator when cooling is not needed, thus saving energy and extending battery life.

[0120] By precisely controlling the heat dissipation system, the battery is always kept at a safe operating temperature, reducing the risk of battery performance degradation or safety hazards caused by overheating.

[0121] Taking into account factors such as vehicle speed, air flow rate and battery temperature, the system can automatically adapt to different driving conditions to ensure intelligent and adaptable cooling control.

[0122] For example, the vehicle is traveling at 120 km / h (first speed). Based on the vehicle's shape, aerodynamic characteristics and speed, the system calculates the air velocity. Assume that according to the fluid dynamics model, when the vehicle speed is 120 km / h, the air velocity is 30 m / s.

[0123] Based on an air velocity of 30 m / s, the system calculates the first theoretical cooling value of air flow on the battery. Assuming that based on the air velocity and the heat exchange efficiency of the battery surface, the theoretical cooling effect of air flow per unit time is calculated to be 2°C / minute.

[0124] Currently, the actual maximum temperature of the solid-state battery is 70°C. The system compares this temperature with the preset temperature value, assuming that the preset temperature value is 80°C.

[0125] The system combines the first theoretical cooling value (2°C / min) and the actual maximum temperature of the electrolyte (70°C) to generate a second cooling instruction, instructing the cooling system to continue cooling in the following period of time to ensure that the temperature does not exceed 80°C.

[0126] Due to the high vehicle speed and high air velocity, the system expects the radiator to be able to effectively use the air flow to dissipate heat. Therefore, the radiator's cooling power may not need to be very high, but only needs to be appropriately adjusted.

[0127] The system adjusts the working mode of the radiator according to the second heat dissipation instruction so that the temperature of the battery fluctuates stably between 70°C and 80°C.

[0128] During the following driving cycle, the system continues to monitor the battery's temperature changes and periodically re-acquires vehicle speed, air flow rate, and battery temperature.

[0129] If the vehicle speed changes (for example, slowing down to 60 km / h), the system will recalculate the air velocity and adjust the cooling strategy. For example, a lower vehicle speed will result in a decrease in air velocity, and the system may need to increase the cooling power of the radiator to compensate for the decrease in air velocity.

[0130] By calculating the vehicle speed and air flow rate in real time, the system can intelligently determine the cooling strategy. When the vehicle speed is high, the system knows that the air flow rate is high, so there is no need to over-rely on the radiator; when the vehicle speed slows down, the system can actively increase the cooling power to avoid overheating of the battery.

[0131] When the vehicle speed is high, the air flow rate is large and the cooling effect is obvious. The system does not need to turn on too much cooling power, thus saving energy. When the vehicle speed is low, the system starts more cooling power as needed to ensure that the battery temperature is maintained within a safe range.

[0132] By precisely controlling the battery temperature, the system effectively avoids battery performance degradation or safety hazards caused by overheating. For example, if the high temperature problem is not handled in time, the battery may experience electrolyte degradation, expansion, or even combustion. Through this technology, the battery temperature is effectively managed to ensure the safety of the vehicle during driving.

[0133] In at least one embodiment of the present application, the method further includes:

[0134] S205, obtaining the vehicle exterior temperature to generate an ambient temperature value;

[0135] S206, comparing the ambient temperature value with an ambient temperature threshold;

[0136] S207, if the ambient temperature value is less than the ambient temperature threshold, calculating a second theoretical temperature drop value per unit time according to the first flow rate and the ambient temperature value;

[0137] S208: Adjust the heat dissipation power of the radiator according to the second theoretical temperature reduction value.

[0138] Please refer to Figure 1-Figure 3 In this embodiment, the system obtains the outside temperature of the vehicle through a sensor and generates an ambient temperature value. The temperature value is the actual temperature of the outside environment at present, and is usually used to evaluate the impact of the external environment on the battery cooling system.

[0139] The car's temperature sensor collects external temperature data in real time and transmits it to the battery management system, which converts it into a usable ambient temperature value as an input parameter for the temperature control system.

[0140] Ambient temperature monitoring is crucial to optimizing the battery temperature control system. Changes in external temperature will directly affect the cooling effect of air flow rate and the working efficiency of the radiator. For example, in cold weather, low temperature may help dissipate heat, but it may also make the battery temperature too low; in hot weather, the external temperature may increase the burden on the radiator and cause the battery to overheat. By monitoring the ambient temperature, the battery's heat dissipation strategy can be adjusted more accurately.

[0141] The system compares the ambient temperature value with a preset ambient temperature threshold. The ambient temperature threshold is a fixed value set according to the design and safety requirements of the battery to determine whether the current ambient temperature meets the battery temperature control requirements.

[0142] The result of the comparison will determine the subsequent heat dissipation strategy: if the outside temperature is low, it may help to cool down; if the ambient temperature is too high, heat dissipation needs to be strengthened.

[0143] The system compares the ambient temperature value with the preset ambient temperature threshold. The preset ambient temperature threshold is manually set when the solid-state battery is designed, such as 25°C or 30°C, which represents the suitable temperature range recognized by the system.

[0144] If the ambient temperature is lower than the ambient temperature threshold, the system will proceed to the next cooling calculation; if the ambient temperature exceeds the ambient temperature threshold, the system may need to take cooling measures using the radiator.

[0145] The ambient temperature threshold comparison helps determine whether the external environmental conditions require adjustment of the cooling strategy. For example, in cold weather (ambient temperature below the set threshold), the external temperature may have a favorable effect on battery cooling, and the system can reduce the radiator workload as needed. At higher temperatures, the system will perform stronger cooling to prevent battery overheating.

[0146] It should be noted that the outside temperature refers to the ambient temperature outside the vehicle, which is usually obtained by an outside temperature sensor (such as an ambient temperature sensor).

[0147] If the ambient temperature value is lower than the preset ambient temperature threshold, the system will calculate a new second theoretical cooling value based on the current ambient temperature and vehicle speed. This cooling value indicates the cooling effect of air flow rate (i.e. air flow speed under the influence of vehicle speed) on the battery temperature.

[0148] The second theoretical cooling value predicts the cooling capacity of air flow under current conditions based on vehicle speed, ambient temperature, and the heat exchange efficiency between the radiator and the battery surface.

[0149] Based on the current ambient temperature and the first flow rate (air velocity), the system uses a heat exchange model or fluid dynamics formula to calculate the additional cooling effect that air flow may bring. This calculation result is a cooling prediction for low temperature ambient conditions.

[0150] By calculating the cooling according to the ambient temperature, the second theoretical cooling value provides an optimized cooling strategy for cold environments. If the outside temperature is low and the air flow rate is fast, the system will predict the cooling effect of the cold air and automatically adjust the cooling strategy to prevent the battery temperature from being too low and ensure the normal operation of the battery.

[0151] Based on the calculated second theoretical cooling value, the system will generate a new cooling instruction to adjust the cooling power of the radiator. If the second theoretical cooling value is high, it means that the low temperature and air flow rate have a good cooling effect on the battery, and the system can reduce the cooling power; if the second theoretical cooling value is low, the system will increase the power of the radiator to compensate for the cooling effect caused by insufficient ambient temperature.

[0152] By calculating the second theoretical temperature drop value, the system intelligently adjusts the power output of the radiator. The radiator may adjust the heat dissipation intensity by increasing or decreasing the flow of coolant, fan speed or other methods to ensure that the battery temperature remains within a safe range.

[0153] Intelligently adjusting the heat dissipation power can dynamically adjust according to changes in the external environment to avoid excessive heat dissipation when the external temperature is low, and to prevent low temperatures from having a negative impact on battery performance. Through precise control, the system ensures that the battery can still maintain optimal performance in a low temperature environment, extending the battery life and avoiding battery damage caused by low temperatures.

[0154] For example, suppose you are driving an electric car that uses a solid-state battery. The car is driving in a cold winter environment with a low outside temperature (e.g. -5°C). In order to ensure that the solid-state battery works properly in this low-temperature environment and avoid battery performance degradation or damage, the vehicle's temperature control system needs to dynamically adjust the heat dissipation power of the radiator.

[0155] The vehicle is equipped with ambient temperature sensors, which obtain the outside temperature in real time. The outside temperature is -5℃.

[0156] The system generates an ambient temperature value based on the sensor data, which is -5°C.

[0157] The system compares the obtained ambient temperature value (-5°C) with the temperature threshold. Assume that the ambient temperature threshold set by the system is 0°C, that is, when the external temperature is lower than 0°C, the system will consider that the ambient temperature has a cooling effect on the battery.

[0158] Because the current ambient temperature (-5°C) is lower than the set ambient temperature threshold (0°C), the system determines that the external environment is cold and needs to take additional measures.

[0159] Next, the system will calculate the second theoretical cooling value based on the vehicle speed and the outside temperature. Assume that the current vehicle speed is 100 km / h (i.e., an air velocity of about 27.8 m / s).

[0160] Due to the high speed of the vehicle and the high air velocity, the vehicle can generate strong air flow, which will increase the cooling effect. The system uses an aerodynamic model to calculate that the theoretical cooling value that air flow can bring per unit time is 4℃ / minute.

[0161] The calculated second theoretical temperature drop value is 4°C / minute, ie, the combination of low ambient temperature and air flow rate is expected to reduce the battery temperature by 4°C per minute.

[0162] Since the ambient temperature is low (-5°C) and the second theoretical temperature drop value is 4°C / minute, the system realizes that the cooling effect of the air flow rate is very strong, so the system will adjust the radiator power according to this data.

[0163] To prevent the battery temperature from dropping too quickly, which may damage the battery performance or cause the battery to operate unstable, the system will avoid excessive cooling by reducing the heat dissipation power of the radiator.

[0164] For example, suppose the system calculates that without proper cooling control, the battery temperature may drop to an unacceptable level over a period of time. To prevent this, the cooling system reduces the intensity of the radiator's operation and activates the radiator only when needed to ensure that the battery temperature is within an acceptable range (e.g., 20°C to 30°C).

[0165] As driving time goes by, the system will continue to monitor vehicle speed and ambient temperature. If the vehicle speed changes (for example, the vehicle speed is reduced or traffic congestion causes the vehicle speed to slow down), the system will recalculate the air flow rate and theoretical cooling value and adjust the radiator power. For example, if the vehicle speed drops to 50km / h, the air flow rate will decrease, the system will calculate the new theoretical cooling value, and increase the radiator power to compensate for the decrease in cooling effect.

[0166] In addition, as the external temperature changes, the system will continuously monitor the temperature outside the vehicle and dynamically adjust the temperature threshold to ensure that the battery temperature is always within a safe range.

[0167] In at least one embodiment of the present application, the method further includes:

[0168] S209: If the ambient temperature value is not less than the ambient temperature threshold, execute the first heat dissipation instruction to adjust the heat dissipation power of the radiator around the solid-state battery.

[0169] Please refer to Figure 1-Figure 3 In this embodiment, when the temperature of the external environment is not less than the set ambient temperature threshold, the subsequent heat dissipation instruction will be triggered. Only when the ambient temperature reaches or exceeds a certain value will the system determine that heat dissipation measures need to be taken to reduce the battery temperature.

[0170] Ensure that the cooling control is activated only when necessary. Avoid unnecessary cooling activation, save energy, and avoid unnecessary cooling when the ambient temperature is low, thereby reducing the energy consumption of the system.

[0171] Avoid unnecessary overcooling of the battery, as the battery's heat dissipation requirements will be relatively large when the ambient temperature is high.

[0172] Once the system detects that the external temperature is too high and confirms that cooling measures need to be taken, the first cooling instruction will be issued. According to this instruction, the radiator starts working. As needed, the cooling power of the radiator will be adjusted to increase the heat dissipation, help the battery dissipate heat, and prevent the internal temperature of the battery from being too high.

[0173] The radiator can be a liquid cooling system (dissipating heat through liquid circulation) or an air cooling system (increasing airflow through fans, etc.), etc. The specific working method depends on the system design and the heat dissipation requirements of the battery.

[0174] By adjusting the heat sink power, the battery temperature can be kept within a safe operating range to avoid overheating, which could lead to performance degradation, reduced charging efficiency, or even dangerous conditions such as thermal runaway.

[0175] Automatically adjusting the radiator power can adjust the system's heat dissipation according to actual needs, avoiding energy waste caused by excessive heat dissipation. It can use energy more efficiently and optimize the operating efficiency of the battery.

[0176] Through real-time temperature monitoring and precise heat dissipation regulation, the operating temperature of the battery can be efficiently managed to avoid performance degradation and safety risks caused by high temperature.

[0177] The system can automatically adjust the power of the radiator according to real-time changes in external ambient temperature, ensuring that the solid-state battery can maintain optimal working conditions under different climatic conditions.

[0178] In at least one embodiment of the present application, the step of periodically acquiring temperature data of a solid-state battery of a vehicle during operation and before generating the first temperature data further includes:

[0179] S301, obtaining the output power of the solid-state battery of the vehicle in this cycle, and generating a first output power value;

[0180] S302, comparing the first output power value with a power threshold;

[0181] S303: If the first output power value is greater than the power threshold, perform periodic data acquisition.

[0182] Please refer to Figure 1-Figure 3 In this embodiment, after monitoring the output power of the solid-state battery, the system generates the first output power value within the cycle, that is, records the power data of the battery.

[0183] By regularly obtaining the battery's output power, you can understand the load of the battery under specific working conditions. When the battery output power is large, the battery will generate more heat and require more effective heat dissipation. Conversely, when the output power is small, the battery will generate less heat and the heat dissipation requirement is relatively low.

[0184] By monitoring the output power of solid-state batteries, we can accurately grasp the battery load conditions and provide data support for subsequent temperature management.

[0185] Effectively identify the heat dissipation requirements during high-load operation, improve the response speed of the heat dissipation system, and ensure safe operation of the battery.

[0186] The system determines whether further heat dissipation control measures need to be taken by comparing the first output power value with the power threshold.

[0187] The system obtains the output power of the battery (the first output power value) and compares it with a preset power threshold. If the output power of the battery is greater than the threshold, it means that the battery is in a high-load working state, and the system will start the next step of heat dissipation control.

[0188] By setting the power threshold, the system can intelligently determine whether the battery is in a high-load working state. This enables the system to make different cooling decisions for different working states, thereby improving the system's energy efficiency and response speed.

[0189] Once the system finds that the battery output power exceeds the preset power threshold, it will start periodic data acquisition, that is, regularly obtain the battery temperature data under this high power load. Real-time tracking of battery temperature and timely response to overheating risks.

[0190] When the battery is under high load, it will generate more heat. Therefore, in order to prevent the battery from overheating, the system needs to obtain the battery temperature data more frequently to ensure that the battery temperature is within a safe range. This ensures that when the battery load is high, the temperature control system can respond in real time to avoid damage to the battery due to overheating.

[0191] By frequently acquiring temperature data, the system can more accurately grasp the temperature change trend of the battery, thereby making timely and effective heat dissipation adjustments to avoid battery overheating.

[0192] Monitor battery temperature in real time to detect overheating risks in time and avoid battery damage or safety hazards caused by overheating.

[0193] Through periodic data acquisition, the system can dynamically adjust the cooling strategy according to changes in battery load to achieve more efficient thermal management.

[0194] By monitoring the battery's output power in real time, the system can accurately determine whether the battery is in a high-load working state and reasonably judge whether it is necessary to obtain temperature data more frequently for temperature control.

[0195] Periodic data acquisition ensures that when the battery is under high load, it can respond quickly to temperature changes and adjust the power output of the cooling system in time to avoid battery overheating.

[0196] Avoid battery overheating and ensure that the battery always operates within a safe temperature range, thereby reducing battery loss and extending battery life.

[0197] Example: Assume that an electric car is traveling at a high speed of 120 km / h. The vehicle's battery management system (BMS) monitors that the output power of the solid-state battery is 350W (the battery provides higher power when traveling at high speeds), and generates a first output power value of 350.

[0198] The power threshold set by the battery management system is 300W, which means that if the battery output power exceeds 300W, the system will think that the battery is working at high load and will cause overheating.

[0199] Since the current battery output power is 350W, which is greater than the power threshold of 300W, the system recognizes that the battery load is high and starts periodic data acquisition.

[0200] The system starts to obtain the battery temperature data regularly. Assume that the system obtains the temperature data every 5 minutes.

[0201] Generate the first temperature data: obtain the battery temperature every 5 minutes. Assume that the battery temperature is 65° C., 68° C., 72° C., etc. each time the data is collected.

[0202] Assume that the preset temperature threshold of the system is 75°C, that is, when the battery temperature exceeds 75°C, the system needs to start the heat dissipation function to prevent the high temperature from affecting the battery performance.

[0203] After obtaining the temperature data, the system determines that the battery temperature has not reached the threshold of 75°C at 72°C, so emergency cooling is not required for the time being.

[0204] Since the battery temperature is still below 75°C, the system continues to monitor the battery temperature changes and obtains data periodically. If the battery load increases, the battery temperature may continue to rise.

[0205] Assume that the external ambient temperature is 15°C (relatively low ambient temperature). Since the external temperature is low, the system believes that the cooling effect of natural wind may be sufficient to help lower the temperature of the battery. Therefore, based on the ambient temperature and vehicle speed, the system can calculate the air flow rate and then calculate the second theoretical cooling value.

[0206] Assuming that the second theoretical temperature drop value is calculated to be 3°C / minute, it means that even without additionally increasing the heat dissipation power, the temperature of the battery can be dropped by 3°C / minute.

[0207] If the battery temperature approaches or exceeds 75°C during subsequent data acquisition, the system will generate a first cooling instruction based on the calculated temperature change trend, instructing the cooling system to increase cooling and keep the battery temperature within a safe range.

[0208] In at least one embodiment of the present application, the method further includes:

[0209] S304, calculating a theoretical heat release value of the electrolyte per unit time according to the first output power value to generate a theoretical heat value;

[0210] S305, obtaining the temperature value of the solid-state battery of the automobile at the beginning of the current cycle, and generating the temperature value of the previous cycle;

[0211] S306, calculating the theoretical calorific value of this cycle according to the theoretical calorific value and the temperature value of the previous cycle, and generating a theoretical temperature rise value;

[0212] S307, adjusting the heat dissipation power of the radiator according to the theoretical increased temperature value.

[0213] Please refer to Figure 1-Figure 3 In this embodiment, when the battery output power (first output power value) is known, the theoretical heat release value of the electrolyte is calculated using these parameters.

[0214] At the beginning of each time period, the battery management system (BMS) obtains the current temperature value of the battery and monitors the battery status in real time through the temperature sensor.

[0215] This is the battery temperature data of the previous cycle, representing the thermal state of the battery in the previous period of time. This temperature value will be used as a reference to compare with the new temperature data to determine whether the battery has an abnormal temperature rise.

[0216] According to the temperature value of the previous cycle and the output power of the battery in the current cycle (i.e., the theoretical heat release value), the heat that may be generated in the current cycle can be calculated. That is, through the relationship between the theoretical heat value and the temperature of the previous cycle, the theoretical temperature rise value of the current cycle can be calculated.

[0217] Based on the calculation results of the theoretical temperature rise value, the system can dynamically adjust the heat dissipation power of the radiator. By adjusting the heat dissipation power (for example, adjusting the flow of the liquid cooling system or increasing the fan speed, etc.), the system can effectively control the battery temperature.

[0218] If it is calculated that the battery temperature will rise above the safety threshold, the cooling system will increase the cooling capacity to ensure that the battery temperature does not exceed the standard; if the battery temperature rise is not obvious, the cooling system can reduce the cooling power to avoid energy waste caused by excessive cooling.

[0219] By combining battery output power, temperature and theoretical temperature rise value, the system can achieve more accurate temperature management.

[0220] Avoid battery damage or safety accidents due to overheating, especially under high load or long working conditions.

[0221] For example:

[0222] During the acceleration of the electric vehicle, it is assumed that the output power of the battery is 350W (the power threshold is set to 300W). The onboard battery management system (BMS) monitors the battery output power in real time and generates a first output power value. At this time, the first output power value is 350W.

[0223] Assume that the preset power threshold is 300W. In this case, the battery output power (350W) is greater than the power threshold. Therefore, the battery management system triggers periodic temperature data acquisition and enters the temperature monitoring mode.

[0224] Based on the output power of 350W, the system calculates the theoretical heat release value of the electrolyte per unit time. Assuming this value is 5W·h. In theory, this means that the battery will release 5 watt-hours of heat per hour.

[0225] At the beginning of the cycle, the battery temperature is monitored by the sensor. Assuming the current temperature is 30°C, this temperature value is the temperature value of the previous cycle.

[0226] The system calculates the theoretical temperature rise value of this cycle based on the calculated theoretical heat value (5W·h) and the temperature of the previous cycle (30℃). Assuming that the heat dissipation efficiency and heat capacity of the battery are fixed, the battery temperature is expected to rise by 1℃, that is, the theoretical temperature rise value is 1℃.

[0227] Since the theoretical temperature rise value is 1°C, the battery management system determines that the current temperature rise is still within the safe range (assuming the temperature threshold is 45°C), so it may not be necessary to activate forced cooling. However, the system may still choose to fine-tune the heat dissipation power of the radiator to enhance heat dissipation to maintain a more stable operating temperature and prevent the temperature from rising further.

[0228] Assume that after a period of continuous operation, the actual maximum temperature of the battery is close to 40°C, but still below the preset temperature threshold of 45°C. Therefore, the BMS system will not immediately start forced cooling, but will adjust the radiator power appropriately according to the temperature increase trend to keep the temperature stable.

[0229] Assuming the outside temperature is 15°C and the vehicle is traveling at 80km / h, the system calculates the air velocity to be about 25m / s, then calculates the second theoretical cooling value that may occur per unit time, and adjusts the radiator power according to this value to further control the battery temperature.

[0230] Assuming the ambient temperature is 30°C, when the system detects that the external temperature is high, it will automatically execute the first cooling instruction to start or enhance the cooling capacity of the radiator to ensure that the battery temperature does not exceed the safety threshold.

[0231] The battery management system (BMS) monitors the battery's output power, temperature and external environmental conditions in real time, dynamically calculates the changing trend of the battery temperature, and intelligently adjusts the radiator power based on the predicted results of temperature increase.

[0232] When the battery temperature is too high, the system can automatically adjust the heat dissipation intensity to prevent overheating and ensure that the battery operates within a safe temperature range, thereby improving battery safety, extending battery life, and optimizing battery energy efficiency.
