[0086] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0087] As an example, the traditional vehicle charging control method involves real-time monitoring of the temperature of the vehicle's charging interface and reporting the temperature signal to the vehicle control system. When the temperature of the charging interface exceeds a preset value, the vehicle control system controls the reduction of the charging current or terminates the charging process, thereby achieving vehicle charging control. However, the preset value is a fixed value set in advance throughout the vehicle's life cycle, which results in a fixed charging control logic that cannot be dynamically adjusted according to the owner's charging habits.

[0088] To address this, this application obtains an initial charging control strategy for the target vehicle; adjusts 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; charges the target vehicle according to the maximum charging current threshold; obtains the current charging data of the target vehicle during the current charging process and historical charging data corresponding to previous charging processes of the target vehicle; updates the initial charging control strategy based on the current charging data and historical charging data to obtain a target charging control strategy corresponding to the initial charging control strategy. The target charging control strategy is used for charging control in the next charging process of the target vehicle. This application's embodiment updates and optimizes the initial charging control strategy of the target vehicle by combining the charging data of the target vehicle during the current charging process and historical charging data to obtain a target charging control strategy for the next charging control, thereby achieving dynamic adjustment of the charging control strategy to adapt to changes in the charging environment and improve charging efficiency, safety, and user experience.

[0089] Example 1

[0090] This application provides a vehicle charging control method, referring to... Figure 1 The diagram illustrates a flowchart of a vehicle charging control method provided in an embodiment of this application, which may specifically include the following steps:

[0091] Step 101: Obtain the initial charging control strategy for the target vehicle;

[0092] In practical implementation, the vehicle charging control method provided in this application embodiment can be applied to a vehicle control system, such as a vehicle controller, to control the charging of the vehicle.

[0093] Specifically, the system first obtains an initial charging control strategy for the target vehicle. The initial charging control strategy can be a pre-set charging control strategy for the target vehicle, such as a charging control strategy specifically set according to charging influencing factors such as the target vehicle's battery type, battery capacity, or charging interface temperature. The initial charging control strategy can also be an initial control strategy generated based on charging data of vehicles of the same model in big data. Furthermore, the initial charging control strategy can also be a charging control strategy updated based on the target vehicle's historical charging data after the target vehicle's last charging ended. This application does not impose any specific restrictions 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: obtaining charging data of vehicles of the same model as the target vehicle; analyzing the charging data of vehicles of the same model to generate an initial control strategy for the target vehicle. Embodiments of this application generate a charging control strategy tailored to the characteristics of the vehicle model using charging data from vehicles of the same model, applicable to new vehicles or vehicles lacking historical charging data. This allows for the rapid provision of a suitable charging control strategy based on the data from vehicles of the same model, quickly adapting to the charging needs of the target vehicle and avoiding low charging efficiency due to strategy mismatch. Furthermore, 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 that serves as a benchmark charging control strategy for other vehicles of the same model. This enables the charging data of the target vehicle to be fed back into the data pool of vehicles of the same model, providing a benchmark strategy for other vehicles of the same model and forming 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: obtaining the charging influencing factors of the target vehicle; and generating an initial control strategy for the target vehicle based on the charging influencing factors. This application embodiment achieves highly personalized charging management by generating an initial charging control strategy specifically based on the charging influencing factors of the target vehicle, ensuring that the charging control strategy is highly matched with the actual needs of the vehicle.

[0096] As another example, in some embodiments of this application, the process of obtaining the initial control strategy of the target vehicle is as follows: The initial control strategy is obtained by updating the charging control strategy based on the historical charging data of the target vehicle after the last charging cycle. In embodiments of this application, the strategy is updated based on the vehicle's historical charging data after each charging cycle, ensuring that the charging control strategy can be continuously optimized as vehicle usage changes.

[0097] Step 102: Adjust 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;

[0098] In this embodiment, the charging control of the target vehicle is mainly based on the vehicle's own charging interface. Therefore, during the vehicle charging process, an initial charging control strategy can be adopted to adjust the charging parameters of the charging interface. For example, the maximum charging current threshold of the charging interface during the current charging process can be adjusted according to the initial charging control strategy. This allows for precise control of the maximum charging current of the charging interface during the charging process by adjusting the maximum charging current threshold in real time.

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

[0100] In this embodiment, the target vehicle is charged according to the adjusted maximum charging current threshold, and the charging speed of the charging interface is dynamically adjusted to avoid overheating of the charging interface and overcharging of the battery, thereby improving charging safety.

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

[0102] In this embodiment of the 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 starts, the state of charge of the battery after charging ends, the charging duration, the charging amount, the initial temperature of the charging interface and the real-time temperature of the charging interface, etc., and further obtain the historical charging data of the target vehicle in each charging process, such as the charging record of the target vehicle during its life cycle.

[0103] Step 105: Update the initial charging control strategy based on 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 to control charging during the next charging process of the target vehicle.

[0104] In this embodiment, the initial charging control strategy is updated and optimized based on the current and historical charging data of the target vehicle to generate a new target charging control strategy, which will be used in the next charging process. This embodiment dynamically adjusts the charging control strategy by combining the vehicle's historical and real-time charging data, achieving continuous optimization of the charging control strategy and forming a closed loop of "strategy optimization - strategy implementation - feedback results - strategy re-optimization." This allows for the specification of personalized charging control strategies based on the target vehicle's charging habits, improving the user experience and effectively solving the problems of rigid charging logic and lack of personalization in traditional charging control methods.

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

[0106] The current charging data is merged with the historical charging data to obtain the target charging data for the target vehicle;

[0107] Based on the target charging data, determine whether the initial charging control strategy meets the preset update conditions;

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

[0109] In this embodiment, after the target vehicle finishes its current charging process, the charging data from this charging process and historical charging data from previous charging processes are summarized and analyzed to form target charging data for the target vehicle. This target charging data comprehensively characterizes the target vehicle's charging behavior. Furthermore, the target charging data is used to determine whether the initial charging control strategy needs to be updated. Specifically, this embodiment pre-sets update conditions for the charging control strategy. If the initial charging control strategy meets the update conditions based on the target charging data, the initial charging control strategy is adjusted to generate a new target charging control strategy. This embodiment determines the timing of strategy updates through preset update conditions, avoiding unnecessary updates, reducing charging process instability caused by frequent strategy changes, and determining whether to update based on the actual charging data of the target vehicle. This allows for strategy updates and optimizations based on clear charging optimization needs, improving the targeting and effectiveness of strategy optimization.

[0110] In a preferred embodiment of this application, the target charging data includes at least the historical highest charging temperature, and the step of determining whether the initial charging control strategy meets the preset update conditions based on the target charging data includes:

[0111] The highest charging temperature percentage information of the target vehicle is generated based on the historical highest charging temperature. The highest charging temperature percentage information includes the percentage of the safe range, the percentage of the warning range, the percentage of the dangerous range, and the percentage of the extreme range.

[0112] If the sum of the proportion of the dangerous zone and the proportion of the extreme zone is greater than a preset specific value, then the initial charging control strategy is determined to meet the update condition.

[0113] In this embodiment, the charging data of the target vehicle includes the historical highest charging temperature. The update condition includes the percentage information of the highest charging temperature of the target vehicle. The percentage information of the highest charging temperature is the proportion of the highest charging temperature of the target vehicle during historical charging processes. The decision to update the charging control strategy is based on the percentage of the vehicle's historical highest charging temperature. Specifically, this embodiment sets multiple ranges for the highest charging temperature during vehicle charging, further determines the percentage of each range based on the historical highest charging temperature in the vehicle charging data, and then updates the initial charging strategy when the sum of the percentages of the dangerous range and the extreme range meets a specific value.

[0114] As an example, refer to Figure 2 In this application embodiment, the safety range is pre-set to 0-T. max1 The warning interval is T. max1 -T max2 The danger zone is T. max2 -T max3 And the limiting interval is T max3 -T max4 The specific value is set to 10%, and the target vehicle is charged 100 times. During each charging cycle, the highest charging temperature was within the safe range 20 times (25%), within the warning range 65 times (65%), within the danger range 10 times (10%), and within the extreme range 5 times (5%). The sum of the danger range and extreme range percentages (15%) is greater than the specific value of 10%. Adjusting the initial charging control strategy and then implementing the adjusted strategy significantly reduces the instances where the vehicle's highest charging temperature falls within the danger and extreme ranges. Optionally, the range and specific value settings can be dynamically adjusted based on the vehicle's charging status; this application does not impose specific limitations on this.

[0115] In a preferred embodiment of this application, the target charging data includes at least the number of historical charging attempts, the historical highest charging temperature, and the historical charging duration. The step of determining whether the initial charging control strategy meets preset update conditions based on the target charging data includes:

[0116] The charging health of the target vehicle is assessed based on the historical number of charging cycles, the historical highest charging temperature, and the historical charging duration to determine the charging health level of the target vehicle. The charging health level includes at least a first level, a second level, a third level, and a fourth level.

[0117] If the target vehicle's charging health level is level three or four, then the initial charging control strategy is determined to meet the update conditions.

[0118] In this embodiment, the update conditions also include the charging health status of the target vehicle. The charging health level of the target vehicle is used to determine whether the charging control strategy needs adjustment. Specifically, the target charging data includes historical charging counts, historical highest charging temperature, and historical charging duration. The charging health of the vehicle is assessed based on these data to determine its charging health level. If the charging health level is level three or four, it indicates poor charging health, requiring adjustment and optimization of the charging control strategy. The optimized charging control strategy then controls the vehicle's charging.

[0119] As an example, a health assessment model is used to determine the vehicle's charging health score based on the number of historical charging cycles, the highest historical charging interface temperature, and the historical charging duration. Then, the charging health level is determined based on the vehicle's charging health score. Specific health assessment models are shown in Tables 1 to 4.

[0128] In a preferred embodiment of this application, the preset update conditions may further include the number of times the initial charging control strategy is used and the charging time of the target vehicle under the initial charging control strategy. Specifically, if the number of times the initial charging control strategy is used to control the vehicle to charge has exceeded a preset value (e.g., 2000 times), the initial charging control strategy is updated; or if the charging time of the target vehicle under the control of the initial charging control strategy exceeds a preset time (e.g., 2000 hours), the initial charging control strategy is updated.

[0129] In a preferred embodiment of this application, the initial charging control strategy includes multiple maximum charging current thresholds for the target vehicle, and adjusting the initial charging control strategy to obtain the target charging control strategy includes:

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

[0131] In this embodiment, the initial charging control strategy includes multiple maximum charging current thresholds for the target vehicle. These maximum charging current thresholds are set for different charging scenarios. The initial charging control strategy is adjusted by modifying the maximum charging current thresholds according to a preset percentage, such as 80%. maxi The maximum charging current threshold (I) is adjusted downwards to obtain the adjusted maximum charging current threshold. maxi =80%I maxi This application embodiment adjusts the maximum charging current threshold by a preset percentage, thereby achieving fine control of the charging current and avoiding overheating caused by excessive current.

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

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

[0134] Based on the real-time temperature value, a target temperature range corresponding to the real-time temperature value is selected from the plurality of temperature ranges;

[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 this embodiment, the initial charging control strategy predefines multiple temperature ranges for the target vehicle, each corresponding to a maximum charging current threshold. Different temperature ranges represent different charging conditions. During charging, the temperature of the target vehicle's charging interface is monitored in real time, and a target temperature range is selected from the predefined ranges based on the real-time temperature value. The maximum charging current threshold of the charging interface is then adjusted to the threshold corresponding to that target temperature range. This embodiment dynamically adjusts the maximum charging current threshold based on the real-time temperature of the charging interface, ensuring that the charging process always operates within a safe range.

[0137] As an example, refer to Figure 3 Two intervals are predefined for the target vehicle, with interval 1 being 0-T. max1 The corresponding maximum charging current threshold is I. max1Interval 2 is T max1 -T max2 The corresponding maximum charging current threshold is I. max2 During the charging process, if the real-time temperature T of the charging interface is 0... <T<T max1 Then the maximum charging current threshold of the charging interface is maintained at I. max1 If the real-time temperature 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 this application, the method further includes:

[0139] The charging lifespan of the target vehicle is predicted based on the historical number of charging attempts, the historical charging duration, and the charging health level. The predicted charging lifespan result of the target vehicle includes at least the expected number of charging attempts and the expected usage duration.

[0140] In a preferred embodiment of this application, the system will also predict the charging life of the target vehicle by analyzing the historical number of charging attempts, historical charging duration, and charging health level, and generate a charging life prediction result for the vehicle. The prediction result includes the expected number of charging attempts, i.e., the number of times the target vehicle can still complete charging before the end of its battery life, and the expected usage duration, i.e., the total usage time the target vehicle can still use before the end of its battery life.

[0141] As an example, a charging life evaluation model is used to predict the charging life of a target vehicle based on historical charging counts (X), historical charging durations (Y), and charging health levels, thereby determining the expected number of charging counts and expected usage duration. The specific charging life evaluation model is shown in Table 5.

[0142] Table 5 Examples of Charging Interface Expected Lifespan Evaluation

[0143] Health level Expected number of charging cycles (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) middle X" = 0.75(10000-X) Y" = 0.75(10000-Y) Difference X" = 0.60(10000-X) Y" = 0.60(10000-Y)

[0144] In a preferred embodiment of this application, a usage report for the target vehicle will also be pushed to the vehicle owner. The usage report includes at least the vehicle's charging health level, charging life prediction results, and usage suggestions. Specifically, the usage suggestions are generated based on data analysis of the target vehicle's historical charging data. By analyzing the historical charging data, the owner's charging habits are determined, and then usage suggestions such as a reasonable SOC range (i.e., charging range), a reasonable charging temperature, and regular checks of the charging interface are pushed based on the owner's charging habits.

[0145] As an example, when the health status is excellent, it is recommended that the owner continue to maintain their usage habits and not update the control strategy; when the health status is good, the owner is prompted to optimize their usage habits based on big data monitoring, and can optionally update the control strategy; when the health status is moderate, the owner is prompted to optimize their usage habits based on big data monitoring, and the control strategy is forcibly updated; when the health status is poor, the owner is prompted to optimize their usage habits based on big data monitoring, the control strategy is forcibly updated, and it is recommended to have the charging port checked by after-sales service.

[0146] Furthermore, vehicle owners can check the charging health level of their vehicle by using the charging health level in the report. If the charging health level is level three or four (i.e., medium or poor), the system will automatically update the charging control strategy. If the charging health level is level two (i.e., good), the report provides vehicle owners with the option to update the charging control strategy. Vehicle owners can decide whether to update the charging control strategy according to their own wishes.

[0147] In the specific implementation process, the health level of the target vehicle is pushed to the target vehicle's screen for visual display. If the target vehicle's health level is level three or four, the initial charging control strategy will be automatically updated. If the target vehicle's health level is level two, a strategy update control will be further displayed on the screen, and the initial charging control strategy will be updated in response to the user's click on the strategy update control. This embodiment of the application achieves intelligent and safe charging management by visually displaying the vehicle's health level and automatically or manually updating the charging strategy according to the health level, while improving user experience and battery life.

[0148] Example 2

[0149] This application provides another vehicle charging control method, referring to... Figure 4 and Figure 5 This involves vehicle control systems and vehicle cloud systems. The vehicle control system includes the vehicle controller, and the vehicle cloud system includes a cloud service data processing center. Specifically, it includes the following steps:

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

[0151] S2. The vehicle controller adopts an initial charging control strategy to send control signals based on 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 charging is completed, the data processing center summarizes and analyzes the charging data to obtain the vehicle's historical charging data.

[0153] S4. The data processing center generates the highest charging temperature percentage information and usage report of the vehicle based on the aggregated historical charging data, and pushes the usage report to the vehicle owner. The usage report includes at least the vehicle's charging health level, charging life prediction results, and usage suggestions.

[0154] S5. The data processing center will determine whether to forcibly update the initial charging control strategy based on the vehicle's highest charging temperature percentage information, charging health level, and the usage of the initial charging control strategy. If the proportion of dangerous and extreme zones in the highest charging temperature percentage information exceeds a specific value, or the vehicle's charging health level is medium or poor, or the number of times the initial charging control strategy is used to control the vehicle to charge has exceeded a preset value, or the charging time of the vehicle under the control of the initial charging control strategy exceeds a preset time, then the initial charging control strategy will be adjusted to obtain a new charging control strategy for the next charging process.

[0155] S6. After receiving the usage report, if the vehicle charging health status in the usage report is good, the owner can send an instruction to the data processing center to decide whether to update the initial charging control strategy.

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

[0157] In the specific implementation process, the vehicle controller will also monitor in real time the compatibility between the temperature sensor and the power terminals, the completeness of the charging data collected by the vehicle controller itself, whether the data processing center provides usage reports, whether the vehicle owner selects to update the control strategy according to the charging health status, and whether the vehicle controller itself dynamically adjusts the maximum charging current threshold based on the real-time temperature value during charging. This ensures the safety, reliability, and efficiency of the charging process, thereby improving the overall technical effect. Specifically, the compatibility between the temperature sensor and the power terminals can be determined by the temperature signal resolution, the temperature difference between the temperature signal and the power terminals, and the temperature delay.
