[0047] As electric vehicle technology matures, it's gaining popularity among users. To ensure safety, the operating status of electric vehicles is a key concern. Currently, the performance parameters of electric vehicles' power batteries and drive motors are typically collected and used to predict the lifespan of the entire vehicle. However, existing methods often produce inaccurate predictions of the vehicle's lifespan.

[0049] Exemplary Implementation Environment

[0050] Please refer to Figure 1 , Figure 1 A schematic diagram of an implementation environment involved in this application.

[0051] In vehicles that use electricity as energy, for example: Figure 1 The electric mixer truck shown includes Figure 2The control system shown may include a vehicle controller area network (CAN) 1 and a power CAN 2, a vehicle communication unit (VCU), a battery management system (BMS), an air conditioning compressor controller, an air conditioning controller, a shifter, a telematics-box (T-BOX), a four-in-one controller, and an instrument. The four-in-one controller includes a power distribution unit (PDU) controller (i.e., a charging station controller), a steering motor controller, an air compressor controller, and a DC converter controller. The BMS, air conditioning compressor controller, air conditioning controller, and four-in-one controller respectively collect parameters of the components they control, and the instrument collects vehicle mileage. The BMS, air conditioning compressor controller, air conditioning controller, and shifter transmit the collected parameters to the T-BOX via the vehicle CAN 1. The four-in-one controller transmits the collected parameters to the T-BOX via the power CAN 2. The instrument transmits the collected parameters to the T-BOX via the vehicle CAN 1 or CAN 2.

[0052] The execution subject of the method provided in the embodiment of the present application is a device with data processing capabilities, such as a controller, a server, etc. When applied to a vehicle, the execution subject can be the vehicle controller of the vehicle.

[0053] Exemplary Methods

[0054] In some embodiments, the present application provides a method for determining vehicle life, such as Figure 3 As shown, the following steps may be included:

[0055] S310, obtaining current operating parameters of multiple components of the target vehicle and corresponding preset parameter thresholds.

[0056] The controllers and management systems of various components in the car collect the current operating parameters of each component and send these parameters to the CAN communication interface.

[0057] The target vehicle represents a vehicle for which the remaining operating life needs to be determined.

[0058] The multiple components include a power assembly and other components outside the power assembly, wherein the power assembly may include at least one of a power battery and a drive motor, and the other components outside the power assembly are components pre-selected by technicians according to needs.

[0059] The current operating parameters indicate the current parameters of the components, such as the current insulation resistance of the power battery, the current total mileage, the total running time of the drive motor, etc.

[0060] The preset parameter threshold is a threshold value pre-set for the parameter item of each component, and is a standard for evaluating the health status of the component. If the current operating parameter is the total running time, the preset parameter threshold is the running time threshold. The preset parameter threshold for each parameter item can be set based on the experience of the technicians, the operating life designed for the component, and other factors.

[0061] The parameters of the power assembly and other components outside the power assembly when operating in the current state are extracted from the parameters received from the CAN communication interface of the target vehicle, and the preset parameter thresholds of multiple components are extracted from the data pre-stored in the target vehicle.

[0062] The current operating parameters can also be obtained by directly extracting the current operating parameters from data collected by controllers, management systems and other equipment of each component, and are not limited to being extracted from parameters received from the CAN communication interface.

[0063] In one embodiment, the preset parameter threshold is updated based on the current operating parameters of various components of the plurality of vehicles when they are replaced.

[0064] The preset parameter threshold of each component may include a preset lifespan, and the current operating parameter may include an already operated lifespan.

[0065] When a component in any of multiple vehicles is replaced, the controller of that vehicle sends the component's lifespan to the cloud platform. The cloud platform then receives the lifespans of the components from the multiple vehicles at the time of replacement. If the difference between the lifespan calculated by the cloud platform and the preset lifespan is within a preset range when the same component is replaced in multiple vehicles, the cloud platform records the lifespan of the component. If the difference between the lifespan calculated by the cloud platform and the preset lifespan is not within the preset range when the same component is replaced in multiple vehicles, the cloud platform updates the preset lifespan based on the lifespans of the component in multiple vehicles. The lifespan represents the lifespan of the component from the first time the vehicle was operated to the current time.

[0066] When the same component is replaced in multiple vehicles, if the difference between the calculated service life and the preset service life calculated by the cloud platform is not within the preset range, it indicates that the service life of the component at the time of replacement was significantly less than or significantly greater than the preset service life. The preset service life is inaccurate and needs to be updated. If the service life of the component in multiple vehicles is greater than the preset service life, the cloud platform increases the preset service life and sends the increased preset service life to the vehicles, updating the preset service life stored in the vehicles to the increased preset service life. If the service life of the component in multiple vehicles is less than the preset service life, the cloud platform decreases the preset service life and sends the decreased preset service life to the vehicles, updating the preset service life stored in the vehicles to the decreased preset service life.

[0067] Alternatively, when a component of any one of multiple vehicles is replaced, the controller of the vehicle sends the component's service life to the controllers of other vehicles (including the target vehicle). If the same component in multiple vehicles is replaced, the difference between the service life calculated by the controller of the target vehicle and the preset service life is within a preset range, the target vehicle records the component's service life; if the same component in multiple vehicles is replaced, the difference between the service life calculated by the target vehicle and the preset service life is not within the preset range, the target vehicle updates the preset service life based on the service life of the component in multiple vehicles.

[0068] When the same component is replaced in multiple vehicles, if the difference between the calculated lifetime and the preset lifetime by the target vehicle's controller is outside the preset range, it indicates that the component's lifetime at the time of replacement was significantly less than or significantly greater than the preset lifetime. The preset lifetime is inaccurate and needs to be updated. If the lifetime of the component in multiple vehicles is greater than the preset lifetime, the target vehicle's controller increases the preset lifetime. If the lifetime of the component in multiple vehicles is less than the preset lifetime, the target vehicle's controller decreases the preset lifetime.

[0069] In the method provided in the embodiment of the present application, the preset parameter threshold is updated by the cloud platform or the vehicle controller based on the current operating parameters of the components of multiple vehicles when they are replaced. The health status of the components can be evaluated more accurately based on the updated preset parameter threshold.

[0070] S320 , for each of the multiple components, determine the remaining operating life of the component based on the current operating parameters of the component and the corresponding preset parameter threshold.

[0071] For each of the multiple components, the current operating parameters of the component are compared with the corresponding preset parameter thresholds, thereby determining the health status of the component and obtaining the remaining operating life of the component.

[0072] In one embodiment, the preset parameter thresholds for the same component may include multiple thresholds, each threshold corresponding to a health status. The current operating parameters of the component are compared with multiple thresholds in the corresponding preset parameter thresholds. The health status corresponding to the threshold satisfied by the current operating parameters is the health status of the component, and the remaining operating life of the component can be determined based on the health status of the component.

[0073] In one embodiment, a difference between a preset parameter threshold and a current operating parameter of a component is calculated, and the difference represents the remaining operating life of the component.

[0074] In one embodiment, a difference between a preset parameter threshold and a current operating parameter of a component is calculated, and a ratio of the difference to the preset parameter threshold is calculated, where the ratio represents the remaining operating life of the component.

[0075] S330: Determine the remaining service life of the target vehicle based on the remaining service life of each component.

[0076] When any of the multiple components reaches the end of its life and cannot operate, it will affect the function of the target vehicle. Therefore, the remaining operating life of each component will affect the remaining operating life of the target vehicle. Based on the remaining operating life of each component, the remaining operating life of the target vehicle can be determined.

[0077] In one embodiment, when any of the multiple components reaches the end of its life and cannot operate, the vehicle cannot operate, and the remaining operating life of the component with the shortest remaining operating life among the multiple components can be used as the remaining operating life of the vehicle.

[0078] In one example, the remaining operating life of the power battery among multiple components of the target vehicle is the shortest. After the power battery life ends, it no longer provides electricity to the target vehicle and the target vehicle cannot operate. The remaining operating life of the power battery is then used as the remaining operating life of the target vehicle.

[0079] In one embodiment, when any one of the multiple components reaches the end of its life and cannot operate, the target vehicle can still operate, and the multiple components simultaneously determine the remaining operating life of the target vehicle. The remaining operating life of the target vehicle can be comprehensively evaluated based on the remaining operating life of the multiple components.

[0080] In one example, the air conditioner in the target vehicle has reached the end of its life and can no longer regulate the temperature inside the vehicle, but the target vehicle can still drive normally. Based on the remaining service life of multiple components, the remaining service life of the target vehicle is comprehensively evaluated.

[0081] The method provided in an embodiment of the present application obtains current operating parameters and corresponding preset parameter thresholds of multiple components of a target vehicle; for each of the multiple components, determines the remaining operating life of the component based on the current operating parameters of the component and the corresponding preset parameter threshold; and then determines the remaining operating life of the target vehicle based on the remaining operating life of each component. The multiple components in the embodiment of the present application include a power assembly and other components outside the power assembly. When determining the remaining life of the target vehicle, not only the impact of the remaining life of the power assembly on the remaining life of the target vehicle is considered, but also the impact of the remaining life of other components in the vehicle on the remaining life of the target vehicle is considered, thereby improving the accuracy of determining the life of the electric vehicle. Moreover, the preset parameter threshold is updated based on the current operating parameters of each component of the multiple vehicles when it is replaced. Based on the updated preset parameter threshold, the component health status can be more accurately evaluated, improving the accuracy of the remaining operating life of each component, thereby further improving the accuracy of the remaining operating life of the target vehicle.

[0082] In one embodiment, other components may include at least one of a low-voltage battery, an air-conditioning compressor, an air compressor, a drying cylinder, a motor water pump motor, a battery water pump motor, a cooling fan motor, and a charging stand.

[0083] The battery management system of the low-voltage battery collects the current operating data of the low-voltage battery. The current operating data of the low-voltage battery may include the current total mileage. The preset parameter threshold of the low-voltage battery may include a preset total mileage to support the operation of the target vehicle.

[0084] The controller of the air-conditioning compressor collects the current operating parameters of the air-conditioning compressor. The current operating parameters of the air-conditioning compressor may include the current total operating time. The preset parameter threshold of the air-conditioning compressor may include the preset total operating time.

[0085] The controller of the air compressor collects the current operating parameters of the air compressor. The current operating parameters of the air compressor may include the current total operating time. The preset parameter threshold of the air compressor may include the preset total operating time.

[0086] The controller of the drying cylinder collects the current operating parameters of the drying cylinder. The current operating parameters of the drying cylinder may include the current total mileage. The preset parameter threshold of the drying cylinder may include a preset total mileage supporting the operation of the target vehicle.

[0087] The controller of the motor water pump collects the current operating parameters of the motor water pump, which may include the current total running time, and the preset parameter threshold of the motor water pump may include the preset total running time.

[0088] The controller of the battery water pump motor collects the current operating parameters of the battery water pump motor. The current operating parameters of the battery water pump motor may include the current total operating time. The preset parameter threshold of the battery water pump motor may include the preset total operating time.

[0089] The controller of the cooling fan motor collects the current operating parameters of the cooling fan motor. The current operating parameters of the cooling fan motor may include the current total operating time. The preset parameter threshold of the cooling fan motor may include the preset total operating time.

[0090] The controller of the charging stand collects the current operating parameters of the charging stand. The current operating parameters of the charging stand may include the total number of current charging times. The preset parameter threshold of the charging stand may include the preset total number of charging times.

[0091] The power assembly may include a power battery and a drive motor. The BMS collects the current operating parameters of the power battery, which may include the power battery's state of health (SOH) and insulation resistance. The drive motor controller collects the current operating parameters of the drive motor, which may include the current total mileage.

[0092] Among them, the definition of SOH can be the ratio of the current capacity of the battery to the rated capacity of the battery, the ratio of the current maximum discharge capacity of the battery to the maximum discharge capacity of a new battery, the ratio of the internal resistance of the current battery to the internal resistance of a new battery, or the ratio of the remaining number of battery cycles to the total number of battery cycles.

[0093] Extracting parameters received from the target vehicle's CAN communication interface: the power battery's state of health (SOH), the current total mileage of the drive motor, and at least one of the following: the current total mileage of the low-voltage battery, the current total operating time of the air conditioning compressor, the current total operating time of the air compressor, the current total mileage of the dryer, the current total operating time of the motor water pump motor, the current total operating time of the battery water pump motor, the current total operating time of the cooling fan motor, and the total number of times the charging station has been charged. Comparing the current operating parameters of each component among the power battery and drive motor, and at least one of the low-voltage battery, air conditioning compressor, air compressor, dryer, motor water pump motor, battery water pump motor, cooling fan motor, and charging station with a preset parameter threshold to determine the component's health and obtain the component's remaining service life. Determine the target vehicle's remaining service life based on the remaining service life of the power battery and drive motor, and at least one of the low-voltage battery, air conditioning compressor, air compressor, dryer, motor water pump motor, battery water pump motor, cooling fan motor, and charging station.

[0094] In one embodiment, the parameters received by the CAN communication interface are multiple identity identification numbers (Identity documents, IDs), each ID includes multiple bytes, the bytes in the ID include the current operating parameters of the components, and the current operating parameters of the multiple components are extracted from the multiple IDs.

[0095] In one example, the CAN communication interface receives parameters for multiple IDs: the second byte of the first ID indicates the state of health of the power battery; bytes 1-4 of the third ID indicate the current total mileage of the low-voltage battery; bytes 1-4 of the third ID indicate the current total mileage of the drive motor; bytes 1-4 of the fourth ID indicate the current total operating time of the air conditioning compressor; bytes 5-8 of the fourth ID indicate the current total operating time of the air compressor; bytes 1-4 of the third ID indicate the current total mileage of the dryer; bytes 6-8 of the fifth ID indicate the current total operating time of the motor water pump; bytes 1-4 of the sixth ID indicate the current total operating time of the battery water pump motor; bytes 6-8 of the fifth ID indicate the current total operating time of the cooling fan motor; and bytes 6-8 of the seventh ID indicate the current total number of times the charging station has been charged. The current total mileage indicated by bytes 1-4 of the third ID can be the total mileage of the vehicle displayed on the instrument panel.

[0096] The method provided in the embodiment of the present application collects the current operating parameters of the power assembly and at least one of the components including the low-voltage battery, air-conditioning compressor, air compressor, dryer, motor water pump motor, battery water pump motor, cooling fan motor and charging stand, calculates the remaining operating life of these components based on the current operating parameters of these components and the corresponding preset parameter thresholds, and determines the remaining operating life of the target vehicle based on the remaining operating life of these components, taking into account the impact of the power assembly and other components on the remaining operating life of the target vehicle, thereby improving the accuracy of determining the life of the electric vehicle.

[0097] In one embodiment, the current operating parameter includes the operating life, and the preset parameter threshold includes the preset life.

[0098] The "Elapsed Life" represents the life of a component from the first operation of the target vehicle to the current time. Depending on the component, the "Elapsed Life" can be the number of times the component has been operated, the total operating time, or the current total mileage. The "Preset Life" can be a preset number of operations, preset operating time, or preset mileage. A component's life ends when the number of operations, total operating time, or current total mileage equals the preset number of operations, preset operating time, or preset mileage.

[0099] Determining the remaining operating life of a component based on its current operating parameters and corresponding preset parameter thresholds may include:

[0100] The difference between the preset life and the actual service life of the component is calculated, and the ratio of the difference to the preset life is calculated to obtain the remaining service life of the component.

[0101] When the preset life of a component is the preset operating time and the operated life is the total operating time, the difference between the preset operating time and the total operating time of the component is calculated, and the ratio of the difference to the preset operating time is calculated. The difference represents the remaining operating time, and the ratio is the ratio of the remaining operating time to the preset operating time. The remaining operating life of the component is the ratio.

[0102] In one embodiment, the preset lifespans of the air-conditioning compressor, air compressor, motor water pump motor, battery water pump motor, and cooling fan motor are all preset operating times, and the already-operated lifespans are all current total operating times. Then, the remaining operating lives of the air-conditioning compressor, air compressor, motor water pump motor, battery water pump motor, and cooling fan motor are the differences between their respective preset operating times and their current total operating times. The ratio of the difference to the preset operating time is calculated, and the difference represents the remaining operating time. The ratio is the ratio of the remaining operating time to the preset operating time. The remaining operating life of the components is this ratio.

[0103] In one example, the preset life of the air conditioning compressor is 2000 hours, the preset life of the air compressor is 5000 hours, the preset life of the motor water pump motor is 10000 hours, the preset life of the battery water pump motor is 10000 hours, and the preset life of the cooling fan motor is 20000 hours.

[0104] When the preset life of a component is the preset number of operations and the actual life is the actual number of operations, the difference between the preset number of operations and the actual number of operations of the component is calculated, and the ratio of the difference to the preset number of operations is calculated. The difference represents the remaining number of operations, and the ratio is the ratio of the remaining number of operations to the preset number of operations. The remaining operating life of the component is the ratio.

[0105] In one embodiment, the preset life of the charging stand is the preset number of operations of the charging stand, and the operated life is the total number of times the charging stand has been charged. The remaining operating life of the charging stand is the difference between the preset number of operations and the total number of times the charging stand has been charged. The ratio of the difference to the preset number of operations is calculated. The difference represents the remaining number of operations. The ratio is the ratio of the remaining number of operations to the preset number of operations. The remaining operating life of the component is this ratio.

[0106] In one example, the preset lifespan of the charging base is 3,000 times.

[0107] When the preset life of a component is the preset mileage and the operating life is the current total mileage, the difference between the preset mileage and the current total mileage of the component is calculated, and the ratio of the difference to the preset mileage is calculated. The difference represents the remaining mileage, and the ratio is the ratio of the remaining mileage to the preset mileage. The remaining operating life of the component is the ratio.

[0108] In one embodiment, the preset lifespans of the drive motor, low-voltage battery, and dryer are all preset mileage, and the actual operating lifespans are all the current total mileage. The remaining operating lifespans of the drive motor, low-voltage battery, and dryer are then calculated as the difference between their respective preset mileages and their current total mileage. The ratio of the difference to the preset mileage is then calculated, with the difference representing the remaining mileage. The ratio is the ratio of the remaining mileage to the preset mileage, and the remaining operating lifespan of the components is calculated as this ratio. In one example, the preset lifespan of the drive motor is 300,000 kilometers, the preset lifespan of the low-voltage battery is 65,000 kilometers, and the preset lifespan of the dryer is 20,000 kilometers.

[0109] The method provided in the embodiment of the present application calculates the remaining service life of multiple components, and based on the remaining service life of these multiple components, the accuracy of the remaining service life of the determined target vehicle can be provided.

[0110] In one embodiment, each component corresponds to a preset weight coefficient.

[0111] Determine the remaining service life of the target vehicle based on the remaining service life of each component, which may include:

[0112] The remaining service life of the target vehicle is determined based on the remaining service life of each component and the corresponding preset weight coefficient.

[0113] The preset weight coefficient of each component is set in advance by technicians based on the degree of influence of each component on the remaining service life of the target vehicle. The greater the influence of the component on the remaining service life of the target vehicle, the greater the preset weight coefficient of the component, and it can be adjusted based on the actual condition of the component. For example: after any component among multiple components is replaced, the probability of failure of the component increases, then the preset weight coefficient of the component is increased.

[0114] The sum of the products of the remaining service life of each component and its preset weight coefficient is calculated, and the sum is used as the remaining service life of the target vehicle.

[0115] In one example, the multiple components include a drive motor, a low-voltage battery, an air conditioning compressor, an air compressor, a dryer, a water pump motor, a battery water pump motor, a cooling fan motor, and a charging station. The remaining operating life of the drive motor, low-voltage battery, and dryer is the ratio of their respective remaining mileage to their preset mileage. The remaining operating life of the air conditioning compressor, air compressor, water pump motor, battery water pump motor, and cooling fan motor is the ratio of their respective remaining operating time to their preset operating time. The remaining operating life of the charging station is the ratio of the remaining number of operations to the preset number of operations.

[0116] Calculate the product of the ratio of the remaining mileage of the drive motor, low-voltage battery and drying drum to the preset mileage and the corresponding preset weight coefficient; calculate the ratio of the remaining operating time of the air-conditioning compressor, air compressor, motor water pump motor, battery water pump motor and cooling fan motor to the preset operating time and the corresponding preset weight coefficient; calculate the ratio of the remaining operating times of the charging stand to the preset operating times and the product of the corresponding preset weight coefficient; calculate the sum of all products and take the sum as the remaining operating life of the target vehicle.

[0117] When the multiple components include a power battery, the current operating data of the power battery is SOH, and the remaining operating life of the power battery is 1-[(1 / 0.3)*(1-SOH)].

[0118] The method provided in the embodiment of the present application calculates the remaining service life of the target vehicle based on the remaining service life of each component and the corresponding preset weight coefficient. The user can inspect and maintain the target vehicle when necessary based on the remaining service life of the target vehicle, providing a basis for the user to inspect and maintain the vehicle.

[0119] In one embodiment, the remaining service life of the target vehicle may be determined based on the remaining service life of each component and the remaining mileage life of the target vehicle.

[0120] The current total mileage of the target vehicle is read from the instrument of the target vehicle, the difference between the preset mileage of the target vehicle and the current total mileage is calculated, the difference is used as the remaining mileage of the target vehicle, and the ratio of the remaining mileage to the preset mileage is calculated to obtain the remaining mileage life.

[0121] Each component corresponds to a preset weight coefficient, and the remaining mileage life of the target vehicle also corresponds to a preset weight coefficient. The product of the remaining operating life of each component and its preset weight coefficient is calculated, and the product of the remaining mileage of the target vehicle and its preset weight coefficient is calculated. The sum of all products is calculated and the sum is used as the remaining operating life of the target vehicle.

[0122] In one example, the multiple components include a power battery, a drive motor, a low-voltage battery, an air conditioning compressor, an air compressor, a dryer, a motor water pump motor, a battery water pump motor, a cooling fan motor, and a charging station. The remaining service life of the target vehicle is calculated based on the remaining service life of the power battery, the drive motor, the low-voltage battery, the air conditioning compressor, the air compressor, the dryer, the motor water pump motor, the battery water pump motor, the cooling fan motor, and the charging station, as well as the remaining mileage life of the target vehicle and their corresponding preset weight coefficients.

[0123] The preset weight coefficients corresponding to each of the above components and the weight coefficients corresponding to the remaining mileage of the target vehicle are as follows:

[0124]

[0125]

[0126] Remaining service life of the target vehicle = remaining service life of the power battery * 30% + remaining service life of the drive motor * 20% + remaining service life of the low-voltage battery * 3% + remaining service life of the air-conditioning compressor * 3% + remaining service life of the air compressor * 5% + remaining service life of the dryer * 3% + remaining service life of the motor water pump motor * 5% + remaining service life of the battery water pump motor * 3% + remaining service life of the cooling fan * 5% + remaining service life of the charging stand * 3% + remaining mileage life of the target vehicle * 20%.

[0127] The method provided in the embodiment of the present application calculates the remaining service life of the target vehicle based on the remaining service life of the components, the remaining mileage life of the target vehicle, and the corresponding preset weight coefficients. By considering more factors affecting the remaining service life of the target vehicle, the determined remaining service life of the target vehicle is more accurate.

[0128] In one implementation, the method may further include:

[0129] When the current operating parameters of any component among the multiple components meet the preset conditions, a prompt message is generated.

[0130] The current operating parameters of the components can reflect the condition of the target vehicle, and the preset conditions can be used to determine whether the condition of the target vehicle is good.

[0131] When the current operating parameters of any of the multiple components meet the preset conditions, it means that the component has an abnormality, which may have an adverse impact on the safe operation of the target vehicle. A prompt message is generated to prompt the user to take action.

[0132] The method provided in the embodiment of the present application generates a prompt message to prompt the user to take action to eliminate the abnormality of the component and maintain the safe operation of the vehicle.

[0133] In one embodiment, the current operating parameter includes the operating life, and the preset parameter threshold includes the preset life;

[0134] When the current operating parameters of any of the multiple components meet the preset conditions, a prompt message is generated, including:

[0135] When the service life of any one of the multiple components reaches a preset service life, a prompt message indicating that the component should be replaced is generated.

[0136] When the service life of any one of the multiple components reaches a preset service life, it indicates that the component needs to be replaced, and a prompt message is generated to prompt the user to replace the component.

[0137] The method provided in the embodiment of the present application generates a prompt message when the service life of a component reaches a preset service life, prompting the user to replace the component to maintain safe operation of the vehicle.

[0138] In one embodiment, the current operating parameters include current operating state parameters.

[0139] The current operating status parameter of a component reflects whether the current operating status of the component is normal.

[0140] The current operating status parameters of the power batteries in the multiple components may include at least one of SOH and insulation resistance.

[0141] When the current operating parameters of any of the multiple components meet the preset conditions, a prompt message is generated, including:

[0142] When the current operating state parameters of any one of the multiple components meet the preset replacement conditions, a prompt message indicating that the component should be replaced is generated.

[0143] When the current operating status parameters of any component among the multiple components meet the preset replacement conditions, it means that the component is damaged or severely aged and can no longer operate normally. A prompt message is generated to prompt the user to replace the component.

[0144] The prompt information may be a fault code. When different parts need to be replaced, different fault codes are generated, and each fault code corresponds to a preset meaning.

[0145] In one example, the power battery's SOH threshold = 1-[(1 / 0.3)*(1-SOH)], with one decimal place rounded and an accuracy of 0.4. When the power battery's SOH threshold is less than 70% (or less than 80% for a ternary lithium battery), a fault code prompting replacement of the power battery is generated.

[0146] When the current operating status parameters of any component among the multiple components meet the preset maintenance conditions, prompt information representing the component to be repaired is generated.

[0147] When the current operating status parameters of any component among the multiple components meet the preset replacement conditions, it indicates that the performance of the component has deteriorated, and a prompt message is generated to prompt the user to inspect the component.

[0148] In one example, when the insulation resistance of the power battery is ≤100 kΩ and lasts for more than 10 minutes, a prompt message is generated to prompt the user to check the fault code of the power battery.

[0149] In one example, a maintenance cycle is set in advance for a component, and each time a maintenance cycle is run, a prompt message is generated to prompt the user to repair the fault code of the component.

[0150] The method provided in the embodiment of the present application generates information prompting the user to replace parts or to repair parts when the parts meet the preset replacement conditions or the preset maintenance conditions, thereby prompting the user to maintain the safe operation of the vehicle.

[0151] In one embodiment, after generating prompt information indicating that a component should be replaced, the method further includes:

[0152] The running life of the target component is sent to the cloud platform, so that the cloud platform updates the preset parameter threshold of the target component according to the running life of the target component.

[0153] The target component is the component corresponding to the prompt information representing the replacement component.

[0154] The preset parameter threshold may include a preset lifespan.

[0155] If the target component is a component whose service life among multiple components meets the preset service life, after replacing the target component, the service life of the target component is sent to the cloud platform, and the cloud platform updates the preset service life of the target component to the sum of the service life and the preset service life of the new target component.

[0156] Alternatively, after the target component is replaced, the controller of the target vehicle updates the preset life of the target component to the sum of the operating life and the preset life of the new target component.

[0157] In one example, the preset life of the low-voltage battery is 65,000 kilometers. After the mileage of the low-voltage battery reaches 65,000 kilometers, the user replaces the low-voltage battery according to the prompt information. The cloud platform or the controller of the target vehicle updates the preset life of the low-voltage battery to 130,000 kilometers based on the running life of the low-voltage battery.

[0158] If the target component is a component among multiple components whose current operating status parameters meet the preset replacement conditions, it means that the target component's operating life has not reached the preset life, but it has been damaged and its performance has been significantly reduced, so it is replaced in advance before the preset life. In this case, the preset life may be inaccurate. The target component's operating life is extracted from the data received from the CAN communication interface and sent to the cloud platform. Other vehicles can also send the target component's operating life to the cloud platform when the above event occurs. The cloud platform adjusts the preset life of the target component based on the operating life of the target component sent by multiple vehicles, and then communicates with the vehicle through the wireless network platform to update the preset life stored in the vehicle to the adjusted preset life.

[0159] After the method provided in the embodiment of the present application generates prompt information representing the replacement of parts, if the target part is a part among multiple parts whose operating life meets the preset life, then after the target part is replaced, the cloud platform updates the preset life of the target part to the sum of the operating life and the preset life of the new target part; if the target part is a part among multiple parts whose current operating status parameters meet the preset replacement conditions, the operating life of the target part is sent to the cloud platform so that the cloud platform updates the preset life of the target part, thereby improving the accuracy of the evaluation of the target part.

[0160] In one embodiment, the method may further include generating a prompt message when the mileage of the target vehicle reaches a preset mileage.

[0161] The preset mileage may be a preset mileage, such as 10,000 kilometers. When the target vehicle travels 10,000 kilometers, a maintenance reminder message is generated.

[0162] The method provided in the embodiment of the present application generates prompt information based on the mileage of the target vehicle, prompting the user to maintain the vehicle and keep the target vehicle running safely.

[0163] In one embodiment, the cloud platform summarizes and analyzes the actual application big data of many vehicles in different geographical areas. When the service life of a component is obviously too short or too long at the time of replacement, the cloud platform updates the preset life of the component. The preset life of the component can also be dynamically adjusted and corrected based on the actual application big data of many vehicles. For example: The default setting of the preset life of the air-conditioning compressor is: 5000 hours, which can be adjusted to: 6000 hours in tropical areas as appropriate, and 3000 hours in the less used areas in the northeast, and can also be adjusted according to the collected atmospheric temperature. The preset life of the adjusted component is then synchronized to the vehicle's application.

[0164] In the method provided in the embodiment of the present application, the cloud platform can adjust the preset life of components based on the actual application big data of many vehicles, thereby improving the accuracy of component evaluation.
