[0086] To make the above objects, features and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0087] As an example, the traditional vehicle charging control method is to monitor the temperature of the vehicle charging interface in real time and report the temperature signal to the vehicle control system. When the temperature of the charging interface exceeds a preset value, the vehicle control system controls to reduce the charging current or end the charging, so as to achieve the charging control of the vehicle. The preset value is a fixed value preset within the vehicle life cycle, and there is a problem that the charging control logic is solidified and cannot be dynamically adjusted according to the charging usage habits of the vehicle owner.

By combining the charging data and historical charging data of the target vehicle during the current charging process, the initial charging control strategy of the target vehicle is updated and optimized in the embodiments of the present application, and a target charging control strategy for the next charging control is obtained, so as to realize dynamic adjustment of the charging control strategy, adapt to the changes in the charging environment, and improve the charging efficiency, safety and user experience.

[0089] Embodiment 1

[0090] The embodiments of the present application provide a control method for vehicle charging. Referring to Figure 1 , a step flowchart of a control method for vehicle charging provided in the embodiments of the present application is shown, and it may specifically include the following steps:

[0091] Step 101, obtain an initial charging control strategy for a target vehicle;

[0092] In a specific implementation process, the vehicle charging control method provided in the embodiments of the present application can be applied to a vehicle control system, such as a vehicle controller, and the charging of the vehicle is controlled through the vehicle controller.

[0093] Specifically, the system first obtains an initial charging control strategy for the target vehicle. The initial charging control strategy can be a charging control strategy preset for the target vehicle, such as a charging control strategy specifically set according to charging influencing factors such as the battery type, battery capacity, or charging interface temperature of the target vehicle. The initial charging control strategy can also be an initial control strategy generated based on the charging data of vehicles of the same model in big data. Additionally, the initial charging control strategy can be a charging control strategy updated according to the historical charging data of the target vehicle after the last charging of the target vehicle. This application does not make specific limitations on this.

[0094] As an example, in some embodiments of this application, the process of obtaining the initial control strategy for the target vehicle is as follows: Obtain the charging data of vehicles of the same model corresponding to the target vehicle; analyze the charging data of vehicles of the same model to generate an initial control strategy for the target vehicle. In the embodiments of this application, an initial charging control strategy is generated based on the charging data of vehicles of the same model according to the characteristics of the model, so as to be applied to new vehicles or vehicles lacking historical charging data. Furthermore, it can quickly provide a suitable charging control strategy through the data of vehicles of the same model, quickly adapt to the charging requirements of the target vehicle, and avoid low charging efficiency caused by strategy mismatch. Further, the charging data of the target vehicle can be combined with the charging data of vehicles of the same model to generate a charging control strategy as the reference charging control strategy for other vehicles of the same model, realizing that the charging data of the target vehicle can be fed back into the data pool of vehicles of the same model to provide a reference strategy for other vehicles of the same model and form data sharing.

[0095] As another example, in some embodiments of this application, the process of obtaining the initial control strategy for the target vehicle is as follows: Obtain the charging influencing factors of the target vehicle; generate an initial control strategy for the target vehicle according to the charging influencing factors of the target vehicle. In the embodiments of this application, an initial charging control strategy is specifically generated according to the charging influencing factors of the target vehicle to achieve highly personalized charging management and ensure that the charging control strategy highly matches the actual needs of the vehicle.

[0096] As another example, in some embodiments of this application, the process of obtaining the initial control strategy for the target vehicle is as follows: Obtain the charging control strategy updated according to the historical charging data of the target vehicle after the last charging of the target vehicle as the initial control strategy. In the embodiments of this application, the strategy will be updated according to the historical charging data of the vehicle after each charging, ensuring that the charging control strategy can be continuously optimized as the vehicle usage situation changes.

[0097] Step 102: Adjust the maximum charging current threshold corresponding to the charging interface of the target vehicle during the current charging process according to the initial charging control strategy;

[0098] In the embodiments of the present application, the charging control of the target vehicle is mainly based on the vehicle's own charging interface. Thus, during the vehicle charging process, an initial charging control strategy can be adopted to adjust the charging parameters of the charging interface. For example, according to the initial charging control strategy, the maximum charging current threshold of the charging interface during this charging process is adjusted, so as to accurately control the maximum charging current of the charging interface during the charging process by adjusting the maximum charging current threshold in real time during the charging process.

[0099] Step 103: Charge the target vehicle according to the maximum charging current threshold;

[0100] In the embodiments of the present application, the target vehicle is charged according to the adjusted maximum charging current threshold, dynamically adjusting the charging speed of the charging interface, avoiding overheating of the charging interface and overcharging of the battery, and improving the safety of charging.

[0101] Step 104: Obtain the current charging data of the target vehicle during this charging process and the historical charging data corresponding to the previous charging processes of the target vehicle;

[0102] In the embodiments of the present application, during the charging process of the target vehicle, the charging data of the target vehicle during this charging process will be collected in real time. The charging data may include the charging method (DC or AC), the state of charge (SOC) of the battery before charging, the state of charge of the battery after charging, the charging duration, the charging amount, the initial temperature of the charging interface, and the real-time temperature of the charging interface, etc. Further, the historical charging data of the target vehicle during previous charging processes is obtained, such as the charging records of the target vehicle during its life cycle.

[0103] Step 105: Update the initial charging control strategy according to the current charging data and the historical charging data to obtain the target charging control strategy corresponding to the initial charging control strategy. The target charging control strategy is used for charging control during the next charging process of the target vehicle.

[0104] In the embodiments of the present application, the initial charging control strategy is updated and optimized based on the current charging data and historical charging data of the target vehicle to generate a new target charging control strategy. The target charging control strategy will be used for the next charging process of the vehicle. In the embodiments of the present application, by combining the historical charging data and real-time charging data of the vehicle, the charging control strategy is dynamically adjusted to continuously optimize the charging control strategy, forming a closed loop of "strategy optimization - strategy implementation - feedback result - strategy re-optimization", so as to realize the formulation of personalized charging control strategies according to the charging habits of the target vehicle, improve the user experience, and effectively solve the problems of fixed charging logic and lack of personalization in traditional charging control methods.

[0105] In a preferred embodiment of the present application, step 101, updating the initial charging control strategy according to the current charging data and the historical charging data to obtain a target charging control strategy corresponding to the initial charging control strategy, includes:

[0106] Combining the current charging data with the historical charging data to obtain target charging data of the target vehicle;

[0107] Determining whether the initial charging control strategy meets a preset update condition according to the target charging data;

[0108] If the initial charging control strategy meets the update condition, adjusting the initial charging control strategy to obtain the target charging control strategy.

[0109] In the embodiment of the present application, after the target vehicle finishes the current charging process, the charging data of the target vehicle in the current charging process and the historical charging data in previous charging processes are summarized and analyzed to form the target charging data of the target vehicle. The target charging data can comprehensively represent the charging behavior of the target vehicle, and further determine whether to update the initial charging control strategy through the target charging data. Specifically, the embodiment of the present application presets an update condition for the charging control strategy. When it is determined based on the target charging data that the initial charging control strategy meets the update condition, the initial charging control strategy is adjusted to generate a new target charging control strategy. The embodiment of the present application determines the timing of strategy update through the preset update condition, avoids unnecessary updates, reduces the instability of the charging process caused by frequent changes in the strategy, and determines whether to update based on the actual charging data of the target vehicle, so as to update and optimize the strategy under the condition of clear charging optimization requirements, and improve the pertinence and effectiveness of strategy optimization.

[0110] In a preferred embodiment of the present application, the target charging data at least includes the historical maximum charging temperature. Determining whether the initial charging control strategy meets a preset update condition according to the target charging data includes:

[0111] Generating the maximum charging temperature ratio information of the target vehicle according to the historical maximum charging temperature, where the maximum charging temperature ratio information includes the ratio of the safe interval, the ratio of the warning interval, the ratio of the dangerous interval, and the ratio of the limit interval;

[0112] If the sum of the ratio of the dangerous interval and the ratio of the limit interval is greater than a preset specific value, it is determined that the initial charging control strategy meets the update condition.

[0113] In the embodiments of the present application, the charging data of the target vehicle includes the historical maximum charging temperature, and the update condition includes the information on the proportion of the maximum charging temperature of the target vehicle. The information on the proportion of the maximum charging temperature is the proportion of the maximum charging temperature during the historical charging process of the target vehicle. It is determined whether to update the charging control strategy based on the proportion of the historical maximum charging temperature of the vehicle. Specifically, in the embodiments of the present application, multiple intervals are set for the maximum charging temperature during the vehicle charging process. Further, the proportion of each interval is determined according to the historical maximum charging temperature in the vehicle charging data. Then, when the sum of the proportions of the dangerous interval and the limit interval meets a specific value, the initial charging strategy is updated.

[0114] As an example, referring to Figure 2 , in the embodiments of the present application, a safety interval of 0 - T max1 , a warning interval of T max1 - T max2 , a dangerous interval of T max2 - T max3 and a limit interval of T max3 - T max4 are preset. The specific value is set to 10%. The number of charging times of the target vehicle is 100 times. Among them, the number of times the maximum charging temperature during previous charging processes is in the safety interval is 20, and the proportion is 25%. The number of times in the warning interval is 65, and the proportion is 65%. The number of times in the dangerous interval is 10, and the proportion is 10%. The number of times in the limit interval is 5, and the proportion is 5%. Among them, the sum of the proportion of the dangerous interval and the proportion of the limit interval is 15% > the specific value of 10%. The initial charging control strategy is adjusted. Then, after charging control is performed through the adjusted charging control strategy, the situation where the maximum charging temperature of the vehicle is in the dangerous interval and the limit interval is significantly reduced. Optionally, the setting of the interval and the specific value can be dynamically adjusted according to the vehicle charging situation, and the present application does not make specific restrictions on this.

[0115] In a preferred embodiment of the present application, the target charging data at least includes the historical charging times, the historical maximum charging temperature, and the historical charging duration. Determining whether the initial charging control strategy meets the preset update condition based on the target charging data includes:

[0116] Evaluating the charging health of the target vehicle based on the historical charging times, the historical maximum charging temperature, and the historical charging duration to determine the charging health level of the target vehicle. The charging health level at least includes a first level, a second level, a third level, and a fourth level;

[0117] If the charging health level of the target vehicle is the third level or the fourth level, it is determined that the initial charging control strategy meets the update condition.

[0118] In an embodiment of the present application, the update condition further includes the charging health status of the target vehicle, and it is determined whether to adjust the charging control strategy according to the charging health level of the target vehicle. Specifically, the target charging data further includes the historical charging times, the historical maximum charging temperature, and the historical charging duration. The charging health of the vehicle is evaluated based on the vehicle's historical charging times, historical maximum charging temperature, and historical charging duration to determine the vehicle's charging health level. If the vehicle's charging health level is the third level or the fourth level, it indicates that the vehicle's charging health is poor. At this time, the charging control strategy needs to be adjusted and optimized, and then the vehicle's charging is controlled through the optimized charging control strategy.

[0119] As an example, a health evaluation model is used to determine the vehicle's charging health score based on the historical charging times, the highest historical charging interface temperature, and the historical charging duration, and then the charging health level is determined according to the vehicle's charging health score. The specific health evaluation model is shown in Tables 1 to 4:

[0128] In a preferred embodiment of the present application, the preset update condition may further include the usage times of the initial charging control strategy and the charging duration of the target vehicle under the initial charging control strategy. Specifically, if the number of times of using the initial charging control strategy to control the vehicle for charging has exceeded the preset value (such as 2000 times), the initial charging control strategy is updated, or if the charging duration of the target vehicle under the initial charging control strategy exceeds the preset duration (such as 2000h), the initial charging control strategy is updated.

[0129] In a preferred embodiment of the present application, the initial charging control strategy includes multiple maximum charging current thresholds for the target vehicle. The adjustment of the initial charging control strategy to obtain the target charging control strategy includes:

[0130] Adjust the maximum charging current threshold of the initial charging control strategy according to a preset percentage to obtain the target charging control strategy.

[0131] In the embodiment of the present application, the initial charging control strategy includes multiple maximum charging current thresholds for the target vehicle, and these maximum charging current thresholds are set for different charging scenarios. The way to adjust the initial charging control strategy is to modify the maximum charging current threshold according to a preset percentage. For example, if the preset percentage is 80%, the initial maximum charging current threshold (I maxi ) is lowered according to the preset percentage to obtain the adjusted maximum charging current threshold (I" maxi = 80%I maxi ). In the embodiment of the present application, the maximum charging current threshold is adjusted by a preset percentage to achieve fine control of the charging current and avoid the problem of overheating during charging caused by excessive current.

[0132] In a preferred embodiment of the present application, the initial charging control strategy includes multiple temperature ranges for the target vehicle and the maximum charging current thresholds corresponding to the temperature ranges. Adjusting the maximum charging current threshold corresponding to the charging interface of the target vehicle during this charging process according to the initial charging control strategy includes:

[0133] Obtain the real-time temperature value of the charging interface of the target vehicle during this charging process;

[0134] Select the target temperature range corresponding to the real-time temperature value from the multiple temperature ranges according to the real-time temperature value;

[0135] Adjust the maximum charging current threshold corresponding to the charging interface to the maximum charging current threshold corresponding to the target temperature range.

[0136] In the embodiment of the present application, the initial charging control strategy predefines multiple temperature ranges for the target vehicle, and each temperature range corresponds to a maximum charging current threshold. Different temperature ranges represent different charging situations. During charging, the temperature of the charging interface of the target vehicle will be detected in real time, and then the corresponding target temperature range will be selected from the predefined temperature ranges according to the real-time temperature value, and the maximum charging current threshold of the charging interface will be adjusted to the threshold corresponding to the target temperature range. In the embodiment of the present application, the maximum charging current threshold is dynamically adjusted according to the real-time temperature of the charging interface to ensure that the charging process is always within a safe range.

[0137] As an example, referring to Figure 3 , two ranges are predefined for the target vehicle. Range 1 is 0 - T max1 , and the corresponding maximum charging current threshold is I max1, the interval 2 is T max1 -T max2 , and the corresponding maximum charging current threshold is I max2 , during the charging process, if the real-time temperature value T of the charging interface satisfies 0 < T < T max1 , then maintain the maximum charging current threshold of the charging interface as I max1 , if the real-time temperature value T of the charging interface is T max1 <T < T max2 , then adjust the maximum charging current threshold of the charging interface to I max2 .

[0138] In a preferred embodiment of the present application, the method further includes:

[0139] Predict the charging life of the target vehicle according to the historical charging times, the historical charging duration, and the charging health level, and obtain the charging life prediction result of the target vehicle, where the charging life prediction result at least includes the expected charging times and the expected usage duration.

[0140] In a preferred embodiment of the present application, the system will also predict the charging life of the target vehicle by analyzing the historical charging times, the historical charging duration, and the charging health level of the target vehicle, generate the charging life prediction result of the vehicle, and the prediction result includes the expected charging times, that is, the number of charging times that the target vehicle can complete before the end of the battery life, and the expected usage duration, that is, the total duration that the target vehicle can be used before the end of the battery life.

[0141] As an example, a charging life evaluation model is used to predict the charging life of the target vehicle according to the historical charging times (X), the historical charging duration (Y), and the charging health level, and determine the expected charging times and the expected usage duration of the target vehicle. The specific charging life evaluation model is shown in Table 5:

[0142] Table 5 Example of the expected life evaluation of the charging interface

[0143] Health level Expected number of charging times (times) X" Expected usage duration (h) Y" Excellent X" = 10000 - X Y" = 10000 - Y Good X" = 0.85(10000 - X) Y" = 0.85(10000 - Y) Medium X" = 0.75(10000 - X) Y" = 0.75(10000 - Y) Poor X" = 0.60(10000 - X) Y" = 0.60(10000 - Y)

[0144] In a preferred embodiment of the present application, the present application will also push a usage report for the target vehicle to the vehicle owner. The usage report at least includes the charging health level, the charging life prediction result, and usage suggestions of the target vehicle. Specifically, the usage suggestions are generated by analyzing the historical charging data of the target vehicle. By analyzing the historical charging data, the charging habits of the vehicle owner are determined, and then reasonable SOC intervals (i.e., charging intervals), reasonable charging temperatures, and regular inspections of the charging interface are pushed according to the charging habits of the vehicle owner.

[0145] As an example, when the health status is excellent, it is recommended that the vehicle owner continue to maintain the usage habits and not update the control strategy; when the health status is good, the vehicle owner is prompted to optimize the usage habits according to the big data monitoring situation, and the update of the control strategy is optional; when the health status is medium, the vehicle owner is prompted to optimize the usage habits according to the big data monitoring situation, and the control strategy is updated forcibly; when the health status is poor, the vehicle owner is prompted to optimize the usage habits according to the big data monitoring situation, the control strategy is updated forcibly, and it is recommended to go to the after-sales service to check the charging interface.

[0146] Furthermore, the vehicle owner can obtain the charging health status of the vehicle through the charging health status level in the usage report. When the charging health status of the vehicle is at the third level or the fourth level (i.e., medium or poor), the system will automatically update the charging control strategy. For the case where the charging health status of the vehicle is at the second level (i.e., good), the usage report provides the vehicle owner with the option of whether to update the charging control strategy, and the vehicle owner can determine whether to update the charging control strategy according to their subjective will.

[0147] In the specific implementation process, the health status level of the target vehicle is pushed to the screen of the target vehicle for visual display; if the health status level of the target vehicle is at the third level or the fourth level, the initial charging control strategy will be automatically updated; if the health status level of the target vehicle is at the second level, a strategy update control is further displayed on the screen, and in response to the user's click operation on the strategy update control, the initial charging control strategy is updated. By visually displaying the health status level of the vehicle and automatically or manually updating the charging strategy according to the health status level in the embodiments of the present application, intelligent and safe charging management is achieved, while the user experience and battery life are improved.

[0148] Embodiment 2

[0149] The embodiments of the present application provide another control method for vehicle charging. Referring to Figure 4 and Figure 5 , it involves a vehicle control system and a vehicle-cloud system. The vehicle control system includes a vehicle controller, and the vehicle-cloud system includes a data processing center for cloud services, and specifically includes the following steps:

[0150] S1. The temperature value of the charging interface is detected in real time through the temperature sensor of the vehicle charging interface, and the temperature value is reported to the vehicle controller. The temperature sensor is fixedly clamped to the power terminal of the charging interface;

[0151] S2. The vehicle controller uses the initial charging control strategy to issue a control signal according to the real-time temperature value to adjust the maximum charging current threshold of the charging interface during the charging process. At the same time, the vehicle controller will collect the charging data of the vehicle during the charging process and transmit the charging data to the data processing center in real time;

[0152] S3. After the charging is completed, the data processing center summarizes and analyzes the charging data to obtain the historical charging data of the vehicle;

[0153] S4. The data processing center generates the highest charging temperature ratio information and usage report of the vehicle based on the summarized historical charging data, and pushes the usage report to the vehicle owner. The usage report includes at least the charging health level of the vehicle, the charging life prediction result, and usage suggestions;

[0154] S5. The data processing center determines whether to force an update of the initial charging control strategy based on the highest charging temperature ratio information of the vehicle, the charging health level, and the usage of the initial charging control strategy. If the ratio of the dangerous interval and the limit interval in the highest charging temperature ratio information exceeds a specific value, or the charging health level of the vehicle is medium or poor, or the number of times of using the initial charging control strategy to control the vehicle charging has exceeded the preset value, or the charging duration of the vehicle under the control of the initial charging control strategy exceeds the preset duration, then adjust the initial charging control strategy to obtain a new charging control strategy for charging control in the next charging process;

[0155] S6. After receiving the usage report, if the charging health of the vehicle in the usage report is good, the vehicle owner can send an instruction to the data processing center to update the initial charging control strategy or not;

[0156] S7. In response to receiving the instruction from the vehicle owner to update the initial charging control strategy, the data processing center adjusts the initial charging control strategy to generate a new charging control strategy.

[0157] In the specific implementation process, the vehicle controller will also monitor the cooperation degree of the temperature sensor and the power terminal in real time, monitor whether the acquisition of its own charging data is complete, monitor whether the data processing center provides a usage report, monitor whether the vehicle owner selects to update the control strategy according to the charging health, and monitor whether the vehicle controller dynamically adjusts the maximum charging current threshold according to the real-time temperature value during the charging process to ensure the safety, reliability, and efficiency of the charging process, thereby improving the overall technical effect. Among them, it can be judged whether the temperature sensor and the power terminal cooperate well through the temperature signal resolution, the temperature difference between the temperature signal and the power terminal temperature, and the temperature delay.
