Technical Field

[0002] The present application relates to the technical field of vehicle fault warning technology, and in particular to a fault warning method, electronic equipment and a vehicle. Background Art

[0003] As vehicles develop, they are generally equipped with larger power batteries. As the power source of the vehicle, the output capacity of the power battery determines the performance and even safety of the vehicle.

[0004] For liquid-cooled power batteries, when the vehicle's power battery temperature is too high or too low, the heat exchange fluid in the chiller (heat exchanger) regulates the temperature of the liquid inside the power battery, and then regulates the temperature of the battery cells. If the heat exchanger lacks heat exchange fluid, it will lead to poor heat exchange, resulting in battery temperature imbalance, affecting battery efficiency. Only when the battery power output is limited will an alarm be issued to prompt maintenance, affecting user use and vehicle safety. Summary of the Invention

[0005] In view of this, the purpose of this application is to propose a fault warning method, electronic equipment and vehicle, so as to identify and alarm in advance when the heat exchanger lacks heat exchange liquid, thereby avoiding vehicle failure caused by battery temperature imbalance.

[0006] Based on the above objectives, the present application provides a fault warning method, which includes:

[0008] In response to the operating state being normal operation, determining whether the heat exchanger of the target vehicle lacks heat exchange liquid based on a comparison result of the temperature change value and the temperature change threshold;

[0009] In response to the lack of heat exchange liquid in the heat exchanger, a fault warning message of lack of heat exchange liquid is generated and sent to the target terminal.

[0010] Based on the above purpose, the present application provides an electronic device, including a memory, a processor, and a computer program stored in the memory and runnable on the processor. When the processor executes the program, it implements the fault warning method provided in any embodiment of the present application.

Furthermore, in response to the operating status being normal operation, it is judged whether the heat exchanger of the target vehicle lacks heat exchange liquid based on the comparison result of the temperature change value and the temperature change threshold, so as to eliminate the interference of the liquid booster pump and more accurately judge whether the heat exchanger lacks heat exchange liquid. In response to the lack of heat exchange liquid in the heat exchanger, a fault warning information of lack of heat exchange liquid is generated and sent to the target terminal, so as to realize early identification and alarm when the heat exchanger lacks heat exchange liquid, avoid vehicle failure caused by battery temperature imbalance, and ensure the safety of the target vehicle and the user.

[0017] Figure 1 is a flow chart of a fault warning method provided by an embodiment of the present application. This method is mainly applicable to identifying a fault caused by a lack of heat exchange liquid in a vehicle's heat exchanger and providing a warning before a battery temperature imbalance occurs. As shown in Figure 1, the method may specifically include the following steps:

[0018] S110 , in response to the active battery temperature adjustment function of the target vehicle being turned on, obtaining in real time a temperature change value of a battery water inlet temperature of the target vehicle within a preset period and an operating status of a liquid booster pump of the target vehicle.

[0019] The target vehicle is a vehicle for fault monitoring. Optionally, the target vehicle is a new energy vehicle. The battery active temperature regulation function is a function that requires external intervention to increase or decrease the temperature of the target vehicle's power battery. The activation of the battery active temperature regulation function indicates that the corresponding execution component of the battery active temperature regulation function is operating normally. The preset cycle is a cycle for detecting changes in the temperature of the battery water inlet. The temperature change value is the difference between the temperature at the end of the preset cycle and the temperature at the beginning. The liquid booster pump can be a pump device such as a water pump for making the liquid flow. The operating status can include normal operation, abnormal operation, and not started.

[0020] Specifically, in response to detecting that the active battery temperature control function of the target vehicle is activated, the battery cooling process needs to be monitored to determine whether there is a fault. The temperature change value of the battery water inlet of the target vehicle within a preset period is obtained in real time to determine whether the temperature increase or decrease meets the temperature control requirements. The operating status of the liquid booster pump of the target vehicle is obtained in real time to determine whether the liquid booster pump is activated and operating normally.

[0021] Based on the above example, the battery active temperature regulation function includes a battery active cooling function. The execution component corresponding to the battery active temperature regulation function is the air conditioning module of the target vehicle. In response to the target vehicle's battery active temperature regulation function being turned on, before obtaining the temperature change value of the battery water inlet temperature of the target vehicle within a preset period and the operating status of the target vehicle's liquid booster pump in real time, it can be determined whether the target vehicle's battery active cooling function is turned on. Specifically, it can be:

[0022] Obtain battery temperature control signals from the target vehicle's battery pack management module in real time, and obtain compressor operation signals from the target vehicle's electric compressor module in real time;

[0023] Determine the temperature regulation type based on the battery temperature regulation signal and judge whether the compressor operation signal is greater than zero;

[0024] In response to the temperature regulation category being battery cooling and the compressor operation signal being greater than zero, obtaining a superheat signal from the target vehicle in real time;

[0025] In response to the overheat signal being within a preset overheat range, it is determined that the active battery cooling function of the target vehicle is turned on.

[0026] The executive component corresponding to the battery active temperature regulation function is the air conditioning module of the target vehicle. The battery temperature regulation signal is used to indicate whether the power battery has activated temperature regulation, and whether it is a signal for battery cooling or battery heating. Temperature regulation categories include battery cooling and battery heating. The compressor operation signal is a signal used to characterize the compressor speed. If the compressor operation signal is greater than zero, it indicates that the electric compressor module is operating; if the compressor operation signal is less than or equal to zero, it indicates that the electric compressor module is not operating. The overheat signal is a signal used to determine whether the refrigerant has a cooling effect. The preset overheat range is a pre-set range used to describe the range in which the overheat signal can meet the requirements of the battery active cooling effect, for example: 0~5℃. If it is too small, the compressor will accumulate liquid, and if it is too large, there will be no cooling effect.

[0027] Specifically, a battery temperature adjustment signal is obtained in real time from the target vehicle's battery pack management module, and a compressor operation signal is obtained in real time from the target vehicle's electric compressor module. Based on the real-time battery temperature adjustment signal, a temperature adjustment category can be determined, for example: 0 for disabled, 1 for battery cooling, -1 for battery heating, etc. Based on the real-time compressor operation signal, it can be determined that if the compressor operation signal is greater than zero, the electric compressor module is operating; otherwise, the electric compressor module is not operating. If the temperature adjustment category is battery cooling and the compressor operation signal is greater than zero, it can be determined that the target vehicle is currently using the air conditioning module to cool the battery. Furthermore, an overheat signal is used to determine whether the refrigerant meets the requirements for active battery cooling. A superheat signal is obtained in real time from the target vehicle to determine whether the overheat signal is within a preset overheat range. If the overheat signal is within the preset overheat range, it is determined that the refrigerant meets the requirements for active battery cooling, and therefore, the active battery cooling function of the target vehicle is enabled. If the overheat signal is not within the preset overheat range, it is determined that the active battery cooling function of the target vehicle is not enabled.

[0028] The method of this embodiment can be executed by a device or equipment with an analysis function. The device or equipment with an analysis function can be a central controller on the target vehicle or a remote cloud server. Preferably, it is executed by a cloud server, such as a TSP (Telematics Service Provider) platform. Analysis and processing by the cloud server can improve analysis efficiency and reduce the processing pressure of the target vehicle. Then, the battery pack management module of the target vehicle can send the battery temperature adjustment signal to the on-board communication device of the target vehicle in real time, and the electric compressor module of the target vehicle can send the compressor operation signal to the on-board communication device of the target vehicle in real time. The battery temperature adjustment signal and the compressor operation signal are sent to the cloud server via the on-board communication device, so that the cloud server can obtain the battery temperature adjustment signal and the compressor operation signal of the target vehicle in real time to determine whether the active cooling function of the battery of the target vehicle is turned on.

[0029] Based on the above example, the overheat signal can be obtained from the target vehicle in real time by any of the following methods:

[0030] Method 1: Obtain the overheat signal from the air conditioning module of the target vehicle in real time.

[0031] Specifically, in response to subsequent analysis and warning by the central controller on the target vehicle, an overheat signal from the air conditioning module is obtained in real time. In response to subsequent analysis and warning by the cloud server, the air conditioning module of the target vehicle can send the overheat signal in real time to the target vehicle's onboard communication device. The onboard communication device then transmits the overheat signal to the cloud server, allowing the cloud server to obtain the overheat signal from the air conditioning module of the target vehicle in real time.

[0032] Method 2: Obtain a pressure signal and a temperature signal from the refrigerant outlet of the heat exchanger of the target vehicle in real time, and determine a superheat signal based on the pressure signal and the temperature signal.

[0033] The pressure signal and the temperature signal may be signals acquired by a pressure and temperature sensor installed at a refrigerant outlet of a heat exchanger of the target vehicle.

[0034] Specifically, in response to subsequent analysis and early warning by the central controller on the target vehicle, the pressure and temperature signals at the refrigerant outlet of the heat exchanger are acquired in real time, and a superheat signal is calculated and determined. In response to subsequent analysis and early warning by the cloud server, the pressure and temperature sensor on the target vehicle transmits the pressure and temperature signals at the refrigerant outlet of the heat exchanger in real time to the target vehicle's onboard communication device, which then transmits the pressure and temperature signals to the cloud server via the onboard communication device. The cloud server then calculates the superheat signal based on the acquired pressure and temperature signals.

[0035] Based on the above example, the battery active temperature regulation function includes a battery active heating function. The execution component corresponding to the battery active temperature regulation function is the air conditioning module of the target vehicle. In response to the target vehicle's battery active temperature regulation function being turned on, before obtaining the temperature change value of the battery water inlet temperature of the target vehicle within a preset period and the operating status of the target vehicle's liquid booster pump in real time, it can be determined whether the target vehicle's battery active heating function is turned on. Specifically, it can be:

[0036] Obtain battery temperature control signals from the target vehicle's battery pack management module in real time, and obtain compressor operation signals from the target vehicle's electric compressor module in real time;

[0037] Determine the temperature regulation type based on the battery temperature regulation signal and judge whether the compressor operation signal is greater than zero;

[0038] In response to the temperature adjustment category being battery heating and the compressor operation signal being greater than zero, obtaining a supercooling signal from the target vehicle in real time;

[0039] In response to the supercooling signal being within a preset supercooling range, it is determined that the active battery heating function of the target vehicle is turned on.

[0040] The active battery temperature control function is implemented by the target vehicle's air conditioning module. The subcooling signal is used to determine whether the refrigerant has a heating effect. The preset subcooling range is a pre-set range that describes the range within which the subcooling signal can meet the battery's active heating requirements. For example, a value greater than 0°C (for example, a value greater than 0°C) will result in no heating effect, while a value greater than 0°C will cause dry grinding in the compressor.

[0041] Specifically, a battery temperature adjustment signal is obtained in real time from the target vehicle's battery pack management module, and a compressor operation signal is obtained in real time from the target vehicle's electric compressor module. Based on the real-time battery temperature adjustment signal, a temperature adjustment category can be determined, for example: 0 for disabled, 1 for battery cooling, -1 for battery heating, etc. Based on the real-time compressor operation signal, it can be determined that if the compressor operation signal is greater than zero, the electric compressor module is operating; otherwise, the electric compressor module is not operating. If the temperature adjustment category is battery heating and the compressor operation signal is greater than zero, it can be determined that the target vehicle is currently using the air conditioning module to heat the battery. Furthermore, a supercooling signal is used to determine whether the refrigerant meets the requirements for active battery heating. The supercooling signal is obtained in real time from the target vehicle to determine whether the supercooling signal is within a preset supercooling range. If the supercooling signal is within the preset supercooling range, it is determined that the refrigerant meets the requirements for active battery heating, and therefore, the active battery heating function of the target vehicle is enabled. If the supercooling signal is not within the preset supercooling range, it is determined that the active battery heating function of the target vehicle is not enabled.

[0042] The method of this embodiment can be executed by a device or equipment with an analysis function, which can be a central controller on the target vehicle or a remote cloud server. Preferably, it is executed by the cloud server, then the battery pack management module of the target vehicle can send the battery temperature adjustment signal to the on-board communication device of the target vehicle in real time, and the electric compressor module of the target vehicle can send the compressor operation signal to the on-board communication device of the target vehicle in real time, and the battery temperature adjustment signal and the compressor operation signal are sent to the cloud server via the on-board communication device, so that the cloud server can obtain the battery temperature adjustment signal and the compressor operation signal of the target vehicle in real time to determine whether the active battery heating function of the target vehicle is turned on.

[0043] Based on the above example, the supercooling signal can be obtained from the target vehicle in real time by any of the following methods:

[0044] Method 1: Obtain the supercooling signal from the air-conditioning module of the target vehicle in real time.

[0045] Specifically, in response to subsequent analysis and warning by the central controller on the target vehicle, a supercooling signal from the air conditioning module is obtained in real time. In response to subsequent analysis and warning by the cloud server, the air conditioning module of the target vehicle can send the supercooling signal in real time to the target vehicle's onboard communication device. The onboard communication device then transmits the supercooling signal to the cloud server, allowing the cloud server to obtain the supercooling signal from the air conditioning module of the target vehicle in real time.

[0046] Method 2: Obtain a pressure signal and a temperature signal from the refrigerant outlet of the heat exchanger of the target vehicle in real time, and determine a subcooling signal based on the pressure signal and the temperature signal.

[0047] Specifically, in response to subsequent analysis and early warning by the central controller on the target vehicle, the pressure and temperature signals at the refrigerant outlet of the heat exchanger are acquired in real time, and a subcooling signal is calculated and determined. In response to subsequent analysis and early warning by the cloud server, the pressure and temperature sensor of the target vehicle can transmit the pressure and temperature signals at the refrigerant outlet of the heat exchanger in real time to the target vehicle's onboard communication device, which then transmits the pressure and temperature signals to the cloud server via the onboard communication device. The cloud server then calculates the subcooling signal based on the acquired pressure and temperature signals.

[0048] Based on the above example, the battery active temperature regulation function includes a battery active heating function. The execution component corresponding to the battery active heating function is the target heating component of the target vehicle. The target heating component is a car heater or an engine. In response to the target vehicle's battery active temperature regulation function being turned on, before obtaining the temperature change value of the battery water inlet temperature of the target vehicle within a preset period and the operating status of the target vehicle's liquid booster pump in real time, it can be determined whether the target vehicle's battery active heating function is turned on by the following method:

[0049] Obtain battery temperature adjustment signals from the battery pack management module of the target vehicle in real time, and operating signals from the target heating components of the target vehicle in real time;

[0050] determining a temperature adjustment category based on a battery temperature adjustment signal, and determining whether a target heating component is operating based on an operating signal;

[0051] In response to the temperature adjustment category being battery heating and the target heating component being in operation, obtaining a circuit temperature of the target heating component from the target heating component in real time;

[0052] In response to a difference between the loop temperature and the battery water inlet temperature being greater than a preset difference, it is determined that the active battery heating function of the target vehicle is turned on.

[0053] The active battery heating function corresponds to the target heating component of the target vehicle, which can be a vehicle heater (Positive Temperature Coefficient, PTC) or engine. The operating signal is a signal indicating the operation of the target heating component. The circuit temperature is the temperature of the heating circuit in the target heating component. The preset differential value is a pre-set value used to describe the difference between the circuit temperature and the battery water inlet temperature to meet the requirements for active battery heating.

[0054] Specifically, the battery temperature adjustment signal is obtained in real time from the battery pack management module of the target vehicle, and the operation signal of the target heating component of the target vehicle is obtained in real time. According to the battery temperature adjustment signal obtained in real time, the temperature adjustment category can be determined, for example: 0 is not turned on, 1 is battery cooling, -1 is battery heating, etc. According to the operation signal of the target heating component obtained in real time, it can be determined whether the target heating component is running. In response to the temperature adjustment category being battery heating and the target heating component being run, it can be determined that the target vehicle is heating the battery through the target heating component at this time. Furthermore, it is necessary to determine whether the target heating component meets the requirements for active battery heating startup through the loop temperature of the target heating component and the battery water inlet temperature. The circuit temperature of the target heating component is obtained from the target heating component in real time, the battery water inlet temperature is obtained from the battery pack management module of the target vehicle, the difference between the circuit temperature and the battery water inlet temperature is calculated, and it is determined whether the difference is greater than a preset difference. In response to the difference being greater than the preset difference, it is determined that the target heating component meets the requirements for starting the battery active heating, and therefore, it is determined that the battery active heating function of the target vehicle is turned on; in response to the difference being less than or equal to the preset difference, it is determined that the battery active heating function of the target vehicle is not turned on.

[0055] S120 : In response to the operating state being normal operation, determining whether the heat exchanger of the target vehicle lacks heat exchange liquid based on a comparison result of the temperature change value and the temperature change threshold.

[0056] The temperature change threshold is used to determine whether the temperature change value meets the normal requirements of the battery's active temperature regulation function in order to avoid sensor errors. The heat exchange fluid is the liquid that exchanges heat in the heat exchanger.

[0057] Specifically, in response to the operating status being normal operation, indicating that the liquid boost pump is not faulty, the temperature change value is compared with the temperature change threshold to obtain a comparison result. In response to the temperature change value being greater than the temperature change threshold, it indicates that the temperature of the power battery has changed significantly, the battery active temperature regulation function is normal, that is, the execution effect is normal, and the target vehicle's heat exchanger is not short of heat exchange liquid. In response to the temperature change value being less than or equal to the temperature change threshold, it indicates that the temperature of the power battery has not changed significantly, and the battery active temperature regulation function is not working properly. Since the battery active temperature regulation function is working properly, it is necessary to meet the three conditions of the liquid boost pump being normal, the battery active temperature regulation function being turned on, and the heat exchanger having sufficient heat exchange liquid. In this case, the liquid boost pump is not faulty, the battery active temperature regulation function is turned on, but there are still problems with the effectiveness of the battery active temperature regulation function. Therefore, it can be determined that the target vehicle's heat exchanger is short of heat exchange liquid.

[0058] S130: In response to the lack of heat exchange liquid in the heat exchanger, generate a fault warning message of lack of heat exchange liquid and send it to the target terminal.

[0059] The heat exchange fluid shortage warning is used to alert the user of the target vehicle that the heat exchanger is short of heat exchange fluid and requires prompt action. The target terminal is a terminal device that can alert the user of the target vehicle, such as the center console display or head-up display.

[0060] Specifically, a lack of heat exchange fluid in the heat exchanger indicates an inability to effectively regulate the power battery's temperature. This condition, if sustained for a period of time, could lead to abnormal battery temperatures, impacting the vehicle's operation and the safety of its occupants. Therefore, a fault warning message indicating a lack of heat exchange fluid is generated and transmitted to the target terminal. This allows users of the target vehicle to receive the warning, enabling timely action and preventing further serious vehicle failures.

[0061] It should be noted that in response to a fault warning issued by the cloud server, the target vehicle's air-conditioning module, battery pack management module, electric compressor module and other modules will transmit various status signal data through GW (Gateway) / CEM (Central Electronic Module) to T-BOX (on-board communication equipment), and then the T-BOX will transmit it to the cloud server. The cloud server will process the obtained relevant signals by cleaning NULL (invalid) values ​​and other processes to ensure the accuracy of the data.

[0062] The fault warning method provided in this embodiment obtains the temperature change value of the battery water inlet temperature of the target vehicle within a preset period and the operating status of the liquid booster pump of the target vehicle in real time in response to the activation of the active temperature adjustment function of the battery of the target vehicle, so as to monitor the status of the target vehicle in real time and facilitate the subsequent timely discovery of the temperature adjustment failure of the battery. Furthermore, in response to the operating status being normal operation, it is judged whether the heat exchanger of the target vehicle lacks heat exchange liquid based on the comparison result of the temperature change value and the temperature change threshold, so as to eliminate the interference of the liquid booster pump and more accurately judge whether the heat exchanger lacks heat exchange liquid. In response to the lack of heat exchange liquid in the heat exchanger, a fault warning information of lack of heat exchange liquid is generated and sent to the target terminal, so as to realize early identification and alarm when the heat exchanger lacks heat exchange liquid, avoid vehicle failure caused by battery temperature imbalance, and ensure the safety of the target vehicle and the user.

[0063] FIG2 is a flowchart of another fault warning method provided by an embodiment of the present application. On the basis of the above-mentioned embodiments, optionally, for the case where the preset period includes a first preset period and a second preset period, the temperature change value includes a first temperature change value corresponding to the first preset period and a second temperature change value corresponding to the second preset period, and the temperature change threshold includes a first temperature change threshold corresponding to the first preset period and a second temperature change threshold corresponding to the second preset period, an exemplary description is given of a method for determining that the heat exchanger of the target vehicle lacks heat exchange liquid, an additional method for identifying a liquid boost pump fault and performing a fault warning is added, and an exemplary description is given. Among them, the explanations of terms that are the same as or corresponding to the above-mentioned embodiments are not repeated here. As shown in FIG2 , the method may specifically include the following steps:

[0064] S210 : In response to the battery active temperature adjustment function of the target vehicle being turned on, obtaining the operating status of the liquid booster pump of the target vehicle in real time.

[0065] Specifically, the operating status of the liquid booster pump of the target vehicle is acquired in real time to determine whether the liquid booster pump is turned on and operating normally.

[0066] S220: In response to the operating status being not started or abnormal operation, determining that the liquid booster pump is faulty, generating fault warning information of the liquid booster pump, and sending the information to the target terminal.

[0067] Among them, the fault warning information of the liquid booster pump is a warning information used to remind relevant users of the target vehicle that the liquid booster pump has failed and cannot operate, and needs to be dealt with in a timely manner.

[0068] Specifically, if the liquid booster pump is not started or is operating abnormally, it indicates that the liquid booster pump is faulty and cannot effectively regulate the temperature of the power battery. Therefore, fault warning information about the liquid booster pump is generated and sent to the target terminal so that users of the target vehicle can receive the fault warning information and take timely action.

[0069] It is understandable that the fault of the liquid boost pump can be determined only by the operating status of the liquid boost pump of the target vehicle. Therefore, the location of this step is not specifically limited.

[0070] S230: In response to the operating state being normal operation, obtaining a first temperature change value of the battery water inlet temperature of the target vehicle within a first preset period.

[0071] The first temperature change value is a change value of the battery water inlet temperature within a first preset period, that is, a difference between the battery water inlet temperature at the end of the first preset period and the battery water inlet temperature at the beginning of the first preset period.

[0072] Specifically, if the operating status is normal, indicating that the liquid booster pump is not faulty, the effectiveness of the battery active temperature regulation function can be determined by monitoring the battery water inlet temperature for a period of time. Accordingly, the battery water inlet temperature at the end of the first preset period and the battery water inlet temperature at the beginning of the first preset period of the target vehicle are obtained, and the difference between the two battery water inlet temperatures is used as the first temperature change value.

[0073] S240 : In response to the first temperature change value being less than the first temperature change threshold, obtaining a second temperature change value of the battery water inlet temperature of the target vehicle within a second preset period.

[0074] The first preset period is before the second preset period, and the first preset period is shorter than the second preset period. For example, if the preset period is 23 minutes, the first preset period is the first 3 minutes of the preset period, and the second preset period is the last 20 minutes of the preset period. The second temperature change value is the change in the battery water inlet temperature during the second preset period, that is, the difference between the battery water inlet temperature at the end of the second preset period and the battery water inlet temperature at the beginning of the second preset period.

[0075] Optionally, the preset period also includes an interval period, and an interval period may be included between the first preset period and the second preset period. The interval period is smaller than the first preset period, and the interval period is usually small, such as 1 minute. In this case, the preset period includes the first preset period, the interval period and the second preset period in sequence.

[0076] Specifically, in response to the first temperature change value being less than the first temperature change threshold, it is preliminarily determined that the heat exchanger's heat exchange performance is poor, and a fault in the liquid booster pump has been ruled out. However, for a more accurate determination, longer monitoring is still required to further assess the heat exchange performance of the heat exchanger. Therefore, the battery water inlet temperature at the end of the second preset cycle and the battery water inlet temperature at the beginning of the second preset cycle are obtained for the target vehicle. The difference between these two battery water inlet temperatures is used as the second temperature change value to determine whether the temperature increase or decrease meets the temperature regulation requirements.

[0077] S250 : In response to the second temperature change value being less than the second temperature change threshold, determining that the heat exchanger of the target vehicle lacks heat exchange liquid.

[0078] Among them, the first temperature change threshold and the second temperature change threshold are pre-set temperature change values ​​for measuring the temperature regulation effect. The first temperature change threshold and the second temperature change threshold can be set according to actual needs. For example, in order to avoid sensor error, they are set to 2°C, etc. The first temperature change threshold and the second temperature change threshold can be the same or different, and no specific limitation is made here.

[0079] Specifically, it is further determined whether the second temperature change value is less than the second temperature change threshold. In response to the second temperature change value being still less than the second temperature change threshold, it indicates that the temperature of the power battery has not been effectively regulated for a long period of time. Therefore, it can be determined that the heat exchanger of the target vehicle lacks heat exchange liquid.

[0080] S260: In response to the lack of heat exchange liquid in the heat exchanger, generate a fault warning message of lack of heat exchange liquid and send it to the target terminal.

[0081] It is understandable that, under normal circumstances, when the heat exchanger lacks heat exchange liquid, the coolant flow of the power battery will be poor and the temperature of the power battery cannot be effectively regulated, which will affect the efficiency of the power battery pack. When the temperature of the power battery is not unbalanced, the vehicle can still drive normally. When the power battery temperature is unbalanced, the power battery power output is limited, and the user will know that it needs to be repaired. The above example method is not to repair after the power battery temperature reaches the alarm threshold, that is, after the power battery temperature is unbalanced, but to pay attention to the vehicle status of the target vehicle in advance, reduce the probability of vehicle failure, ensure travel safety, and facilitate after-sales maintenance.

[0082] Based on the above example, the fault warning information includes application warning information and / or service station warning information, and the target terminal includes the mobile terminal and / or service station terminal corresponding to the target vehicle. Then, the fault warning information of lack of heat exchange liquid can be generated and sent to the target terminal in any one or both of the following ways:

[0083] Method 1: Determine surrounding service stations based on the current location of the target vehicle; combine the lack of heat exchange liquid in the heat exchanger and the service station information of the surrounding service stations to generate application warning information, and send the application warning information to the mobile terminal corresponding to the target vehicle.

[0084] The current location is the location of the target vehicle at the time of the fault warning, which can be obtained through the positioning module. The surrounding service stations are vehicle service stations within a preset distance from the current location. Service station information is information describing the surrounding service stations, such as the service station name, address, phone number, business hours, etc. Application warning information is used to send warning information to the application on the mobile terminal of the bound user (such as the owner) of the target vehicle.

[0085] Specifically, the system receives the current location of the target vehicle from its positioning module and identifies one or more nearby service stations based on the pre-registered service station addresses for each vehicle. The system combines the heat exchanger's lack of heat exchange fluid with the service station information of these nearby service stations to generate an application warning message. This warning message is then sent to the target vehicle's associated mobile device, allowing the target vehicle's associated user to promptly view the warning message on their mobile device and proceed to a nearby service station for processing.

[0086] Method 2: Determine surrounding service stations based on the current location of the target vehicle; combine the lack of heat exchange liquid in the heat exchanger and the vehicle information of the target vehicle to generate service station warning information, and send the service station warning information to service station terminals at surrounding service stations.

[0087] The vehicle information is information describing the target vehicle, such as the license plate number, vehicle model, owner's name, owner's contact information, etc. The service station warning information is warning information sent to service station terminals at surrounding service stations.

[0088] Specifically, the current location of the target vehicle is received from the positioning module of the target vehicle, and one or more nearby service stations are determined based on the pre-entered service station addresses of each vehicle. The heat exchanger lack of heat exchange fluid and the vehicle information of the target vehicle are combined to obtain a service station warning message, which is then sent to the service station terminals of the surrounding service stations. This allows the staff of the surrounding service stations to promptly notify the owner of the target vehicle that the target vehicle has a problem with the heat exchanger lacking heat exchange fluid, and remind the owner to go to a nearby service station for treatment or arrange for on-site treatment.

[0089] Optionally, the method for determining the surrounding service stations based on the current position of the target vehicle may be: judging whether there is a vehicle service station within a preset distance from the current position of the target vehicle; in response to the existence of a vehicle service station within the preset distance, determining each vehicle service station within the preset distance from the current position as a surrounding service station; in response to the absence of a vehicle service station within the preset distance, determining the vehicle service station with the smallest distance from the current position as a surrounding service station.

[0090] Optionally, in response to the existence of at least two surrounding service stations, after receiving the reminder and notification issued by any surrounding service station, the processed information is sent to the remaining surrounding service stations to mark the service station warning information in the remaining surrounding service stations as processed.

[0091] Among them, the processed information is used to indicate that the corresponding service station warning information has been responded to and no further processing is required.

[0092] Specifically, in response to the existence of at least two surrounding service stations, after any surrounding service station issues a reminder and notification to the vehicle owner, the service station warning information in the remaining surrounding service stations is marked as processed, avoiding multiple surrounding service stations from reminding and notifying the owner of the target vehicle.

[0093] The fault warning method provided in this embodiment obtains the operating status of the liquid booster pump of the target vehicle in real time in response to the active temperature adjustment function of the battery of the target vehicle being turned on. Furthermore, in response to the operating status being not started or operating abnormally, the liquid booster pump is determined to be faulty, and fault warning information of the liquid booster pump is generated and sent to the target terminal to give a warning of the fault of the liquid booster pump to avoid battery temperature imbalance. In response to the operating status being normal operation, a first temperature change value of the battery water inlet temperature of the target vehicle within a first preset period is obtained to monitor the status of the target vehicle in real time. In response to the first temperature change value being less than a first temperature change threshold , then obtain a second temperature change value of the battery water inlet temperature of the target vehicle within the second preset period to further monitor the status of the target vehicle, facilitate phased analysis, and subsequently promptly discover the temperature regulation failure of the battery. In response to the second temperature change value being less than the second temperature change threshold, it is determined that the heat exchanger of the target vehicle lacks heat exchange liquid. Through the two-stage comparison and judgment, the accuracy of judging whether the heat exchanger lacks heat exchange liquid is improved, and the failure of the liquid booster pump and the lack of heat exchange liquid in the heat exchanger are recognized and alarmed in advance, thereby avoiding vehicle failure caused by battery temperature imbalance and ensuring the safety of the target vehicle and the user.
