[0002] With the popularization of new energy vehicles, battery charging control technology has become crucial for ensuring vehicle performance and extending battery life. The core of the "retirement strategy" is to protect the battery during charging, aiming to extend battery life and ensure vehicle safety and reliability by optimizing charging and discharging strategies after the battery has reached a certain lifespan. Currently, battery charging control methods for new energy vehicles typically make charging decisions based on simple battery capacity or preset mileage estimates, often ignoring the dynamic changes in actual driving conditions, such as the impact of different road conditions, driving habits, and vehicle load on energy consumption. This leads to unreasonable activation of the retirement strategy and poor battery charging protection. Summary of the Invention

The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0016] Furthermore, it should be noted that the acquisition, storage, use, and processing of data in the embodiments of this application all comply with the relevant provisions of national laws and regulations. It should also be noted that certain software, components, models, and other existing industry solutions may be mentioned in the embodiments of this application. These should be considered exemplary, intended only to illustrate the feasibility of implementing the technical solution of this application, and do not imply that the applicant has already used or necessarily used such solutions.

[0017] To address the technical problems, embodiments of this application provide a battery charging control method, apparatus, device, medium, product, and vehicle. The battery charging control method provided in this application embodiment will be described first below.

[0018] Figure 1 A schematic flowchart of a battery charging control method according to an embodiment of this application is shown. Figure 1 As shown, the battery charging control method may include: Step 101: Obtain the first power consumption corresponding to the N driving conditions of the vehicle; N is an integer greater than 1.

[0019] In step 101, the vehicle can upload relevant data to the cloud platform during operation, so that historical data can be retrieved from the cloud platform later. The corresponding driving conditions of the vehicle can be found from the cloud platform, where a gear signal of 1 can be marked as the beginning of a driving condition, and a gear signal of 0 can be marked as the end of the driving condition.

[0020] The system can obtain the first power consumption corresponding to N driving conditions. The number of historical cumulative driving conditions can be set according to needs. It is understandable that the more conditions there are, the more comprehensive the sample coverage, and the more accurate the subsequent calculation results. The fewer conditions there are, the less computation is required. Therefore, a balance between the accuracy of the calculation results and the computational load can be considered, and an appropriate number of driving condition data points can be used for subsequent calculations.

[0021] The first power consumption can refer to the total power consumed per unit distance, which includes the power consumed by driving and the vehicle, as well as the power consumed by accessories such as air conditioning, cabin, and headlights.

[0022] In some examples, the vehicle's battery management can directly calculate the first power consumption corresponding to each driving condition and upload it to the cloud platform so that it can be obtained directly from the cloud platform in the future.

[0023] In some embodiments, obtaining the first power consumption corresponding to N driving conditions of the vehicle may include: The system obtains the first pure electric driving mileage and the first historical cumulative battery level at the start of the first driving condition, and the second pure electric driving mileage and the second historical cumulative battery level at the end of the first driving condition; the first driving condition is any one of the N driving conditions. Based on the first pure electric driving mileage, the first historical cumulative battery charge, the second pure electric driving mileage, and the second historical cumulative battery charge, the first energy consumption corresponding to the first driving condition is determined.

[0024] In this embodiment, the vehicle can upload the pure electric driving mileage and historical cumulative battery charge at the start and end times of each driving condition to the cloud platform. Subsequently, any driving condition can be retrieved from the cloud platform, namely, the first pure electric driving mileage and first historical cumulative battery charge at the start time of the first driving condition, and the second pure electric driving mileage and second historical cumulative battery charge at the end time of the first driving condition.

[0025] The first energy consumption corresponding to the first driving condition can be determined based on the first pure electric driving mileage, the first historical cumulative energy consumption, the second pure electric driving mileage, and the second historical cumulative energy consumption. The formula for calculating the first energy consumption is shown in formula (1): Among them, EC1 is the first energy consumption, EV_Odo1 is the first historical cumulative energy consumption, EV_Odo2 is the second historical cumulative energy consumption, Total_Energy1 is the first pure electric driving range, and Total_Energy2 is the second pure electric driving range.

[0026] In this way, by using actual mileage and power consumption data, the accuracy and traceability of the first power consumption calculation are ensured. The method is simple and direct, easy to implement in the vehicle system, and provides a reliable data foundation for subsequent corrections.

[0027] Step 102: Based on the proportion of driving power consumption of the vehicle, the first power consumption is corrected to obtain the second power consumption; the second power consumption is used to characterize the equivalent power consumption corresponding to the first power consumption when the proportion of driving power consumption is 100%.

[0028] In step 102, the vehicle's driving energy consumption ratio refers to the percentage of energy specifically used for driving, calculated after deducting the energy consumption of other devices such as air conditioning and cabin equipment, considering that not all battery power is used for driving. This driving energy consumption ratio can be calculated by combining the vehicle's historical driving data and taking into account the user's driving habits.

[0029] In some embodiments, the method for determining the proportion of drive power consumption is as follows: Obtain the bus current and bus voltage of the motor corresponding to N driving conditions; Based on the bus current and bus voltage of the motor corresponding to N driving conditions, the historical cumulative drive power consumption is determined. The proportion of driving energy consumption of a vehicle is determined based on its historical cumulative driving energy consumption and the vehicle's historical cumulative total energy consumption.

[0030] In this embodiment, the bus current and bus voltage of the motor corresponding to each driving condition can be collected in real time. Based on the product of the bus current and the bus voltage, the instantaneous drive power can be obtained. Then, by integrating the instantaneous drive power of each driving condition over time, the actual drive power consumption of each driving condition can be calculated.

[0031] The actual driving power consumption for each driving condition is accumulated to obtain the historical cumulative driving power consumption. Alternatively, the total historical cumulative power consumption can be obtained based on the first power consumption corresponding to each driving condition.

[0032] The ratio of historical cumulative driving energy consumption to historical cumulative total energy consumption can be determined as the driving energy consumption ratio of the vehicle. The formula for calculating the driving energy consumption ratio (DP) is shown in formula (2): The first energy consumption can be corrected based on the proportion of driving energy consumption of the vehicle to obtain the equivalent energy consumption corresponding to the first energy consumption when the proportion of driving energy consumption is 100%, which is the second energy consumption. The formula for calculating the second energy consumption is as shown in formula (3): Among them, EC1 is the first power consumption, EC2 is the second power consumption, and DP is the proportion of drive power consumption.

[0033] In this way, calculating drive power consumption based on motor operating parameters provides an objective and direct measurement method, reducing subjective estimation errors. Furthermore, determining the proportion of drive power consumption by the ratio of drive power consumption to total power consumption ensures the accuracy of the drive power consumption proportion, thereby improving the reliability of the first power consumption correction and making the second power consumption more accurately reflect drive energy consumption.

[0034] Step 103: Determine the vehicle's full-charge range based on the second energy consumption corresponding to each driving condition and the vehicle's battery pack charge.

[0035] In step 103, the target energy consumption that accurately reflects the driving force consumed under various driving conditions can be determined based on the second energy consumption corresponding to each driving condition. For example, in some examples, the energy consumption value with a large distribution of second energy consumption can be determined as the target energy consumption, or the target energy consumption can be determined based on the average value of the second energy consumption corresponding to all driving conditions.

[0036] The vehicle's range on a full charge can be determined by multiplying the target energy consumption by the battery pack capacity. The range on a full charge represents the distance a vehicle can travel when fully charged, assuming 100% driving energy consumption.

[0037] In some embodiments, determining the vehicle's full-charge range based on the second energy consumption corresponding to each driving condition and the vehicle's battery pack capacity may include: The average energy consumption of the vehicle is determined based on the second energy consumption corresponding to each driving condition. The vehicle's range on a full charge is determined based on the vehicle's battery pack capacity and average energy consumption.

[0038] In this embodiment, the average value of the second power consumption corresponding to all driving conditions can be calculated to obtain the average power consumption. The formula for calculating the average power consumption is as shown in formula (4): in, EC2 represents the average power consumption, while EC2 represents the second highest power consumption. i It can represent all driving conditions.

[0039] The full-charge range of a vehicle can be determined based on its battery pack capacity and average energy consumption. The formula for calculating the full-charge range is shown in formula (5): In this way, by reflecting the overall driving behavior through average power consumption, the randomness of single-segment driving conditions is avoided, making the full-charge range estimation more stable and reliable. Combined with the calculation of battery pack capacity, it is simple and easy to implement, reduces the computational complexity, and improves the practicality and real-time performance of the method.

[0040] Step 104: Determine the equivalent pure electric driving range based on the vehicle's historical cumulative battery charge, battery pack charge, and full charge range.

[0041] In step 104, the equivalent pure electric driving range can characterize the total pure electric driving range corresponding to the vehicle's historical cumulative battery charge when the driving power consumption ratio is 100%.

[0042] The equivalent pure electric driving range can be calculated based on the vehicle's historical cumulative battery charge, battery pack charge, and full-charge mileage. The formula for calculating the equivalent pure electric driving range is shown in formula (6): Step 105: If the equivalent pure electric driving range meets the preset retirement conditions, activate the retirement strategy to charge the vehicle's battery.

[0043] In step 105, the preset retirement conditions can be set according to actual needs. For example, if the equivalent pure electric driving range is greater than or equal to a preset mileage threshold, the preset retirement conditions can be considered met. Alternatively, even if the equivalent pure electric driving range is less than the mileage threshold, if the vehicle's pure electric range signal is greater than or equal to the preset mileage threshold, the preset retirement conditions can also be considered met.

[0044] Under the condition that the preset retirement conditions are met, the retirement strategy is activated to charge the vehicle's battery in order to achieve charging protection.

[0045] In some embodiments, when the equivalent pure electric driving range meets preset retirement conditions, activating the retirement strategy to charge the vehicle's battery may include: If the maximum value of the equivalent pure electric driving range and the vehicle's pure electric range signal is greater than or equal to the mileage threshold, the retirement strategy is activated to charge the vehicle's battery.

[0046] In this embodiment, the larger value can be determined from the equivalent pure electric driving range and the vehicle's pure electric range signal. Then, this value is compared with the mileage threshold. If it is greater than or equal to the mileage threshold, it can be considered that the preset retirement conditions are met, and the retirement strategy can be activated to charge the vehicle's battery.

[0047] By comparing the equivalent pure electric driving range with the maximum value of the pure electric range signal, the conservatism and safety of the charging triggering conditions are ensured, avoiding premature or late charging due to estimation errors, and further improving the rationality of the retirement strategy.

[0048] In some embodiments, a retirement strategy may include at least one of the following: Reduce the maximum charging power limit; Reduce the maximum charging current limit; Reduce the maximum charging capacity limit; Narrow the charging temperature limit range.

[0049] In this embodiment, if the retirement strategy is activated, the upper limit of the battery's State of Charge (SOC) can be reduced from 100% to a more conservative value, such as 80% to 90%, during battery charging to reduce battery aging at high SOC. The battery charging power limit can also be reduced, as can the maximum charging current during charging, thus reducing the thermal load and stress on the battery during charging. Furthermore, the battery temperature is more strictly controlled during charging to ensure that the battery charges within its optimal temperature range. In extreme environments of high or low temperatures, the charging power is further reduced or charging is paused until the temperature returns to a safe range.

[0050] In this way, the retirement strategy reduces battery stress during the charging process by lowering charging parameter limitations, which helps to slow down battery aging and extend battery cycle life.

[0051] The battery charging control method, apparatus, device, medium, product, and vehicle of this application embodiment can obtain the first power consumption corresponding to N driving conditions of the vehicle; N is an integer greater than 1; the first power consumption is corrected based on the driving power consumption ratio of the vehicle to obtain the second power consumption; the second power consumption is used to characterize the equivalent power consumption corresponding to the first power consumption when the driving power consumption ratio is 100%; the full charge range of the vehicle is determined based on the second power consumption corresponding to each driving condition of the vehicle and the battery pack capacity of the vehicle; the equivalent pure electric driving range is determined based on the historical cumulative power consumption of the vehicle, the battery pack capacity, and the full charge range; when the equivalent pure electric driving range meets the preset retirement conditions, the retirement strategy is activated to charge the battery of the vehicle.

[0052] This approach integrates vehicle usage history and eliminates interference from auxiliary energy consumption, making energy consumption calculations more closely reflect actual driving conditions. This improves the accuracy of full-charge range and equivalent pure electric driving range, makes the retirement strategy activation more reasonable, enhances battery charging protection, and helps extend battery life.

[0053] To facilitate understanding of the battery charging control method provided in the above embodiments, the following description uses a specific scenario embodiment to illustrate the battery charging control method. For example... Figure 2 As shown, this scenario embodiment may include: Step 201: Upload vehicle data to the cloud platform; Step 202: Determine the driving conditions of each vehicle; Step 203: Calculate the power consumption for each operating condition based on the pure electric mileage and cumulative power consumption at the start and end times; Step 204: Calculate the average power consumption under all operating conditions; Step 205, calculate the proportion of drive energy consumption; Step 206: Correct the average energy consumption; Step 207, Calculate the average range on a full charge; Step 208: Calculate the total pure electric driving range and take the larger value of the pure electric range signal from the vehicle. Step 209: Determine whether the threshold is exceeded; if yes, proceed to step 210; otherwise, proceed to step 211. Step 210: Activate the retirement strategy; Step 211: Do not enable the retirement policy.
