Description

Technical Field

[0001] The present application relates to the field of vehicle control technology, and in particular to a battery charging method, device, electronic equipment and vehicle. Background Art

[0002] In new energy vehicles, low-voltage batteries are responsible for providing power to electronic devices when the vehicle is powered off. If the battery is not recharged for an extended period after the vehicle is powered off, it may become severely depleted, rendering the vehicle unable to start. Therefore, proper battery recharge management is crucial.

[0003] Related technologies typically use a fixed-interval method to recharge batteries. That is, when a vehicle is powered off, the battery is recharged at fixed intervals. However, battery power consumption varies significantly depending on vehicle usage frequency. Therefore, in some cases, significant battery power consumption requires timely recharging. However, using a fixed-interval method to recharge batteries fails to ensure timely recharging.

[0004] Another related technology determines the remaining battery charge and voltage, as well as the remaining power battery charge, and only recharges the battery when the remaining battery charge or voltage is low and the remaining power battery charge is greater than a preset charge. This approach, which only recharges the battery when the remaining charge or voltage is low, can cause the battery to remain in a low state of charge or voltage for extended periods. Furthermore, when the remaining power battery charge is low, recharging the battery cannot be performed promptly. A battery in this low state of charge or voltage over extended periods of time will accelerate the reduction of its service life. Therefore, current control strategies for recharging batteries have poor recharging effectiveness. Summary of the Invention

[0005] The present application provides a battery charging method, device, electronic equipment and vehicle. The purpose of the present application is to at least solve the technical problem of poor charging effect of the control strategy for charging the battery in the related art.

[0006] In order to achieve the above objectives, the technical solutions adopted in this application are as follows:

[0007] According to the first aspect provided by the present application, a battery charging method is provided, which includes: obtaining a user's charging preference data and vehicle operation data for a vehicle; determining a target time point for charging the battery based on the charging preference data and the vehicle operation data; and charging the battery at the target time point.

[0008] Based on the above technical measures, the present application determines a target time for battery recharging based on a user's charging preference data and vehicle operation data, thereby recharging the battery at the target time. Thus, based on the user's charging preference data, the user's charging habits can be determined, such as when to charge, how long to charge, whether to charge only when the battery is depleted, and whether to fully charge the battery. Furthermore, based on the vehicle operation data, the user's vehicle usage habits can be determined, such as how often the vehicle is used, how far each trip is made, and how long each trip takes. Furthermore, based on the user's charging preference data and vehicle operation data, the battery's status, such as the remaining battery charge or the recharging status, can be assessed. The target time for the next battery recharging can then be determined, allowing the battery to be recharged at the target time. This can improve the effectiveness of battery recharging based on the user's charging preference data and vehicle operation data, ensuring timely recharging and avoiding low battery sound signals that could affect the battery life or vehicle usage.

[0009] In one possible implementation, the above-mentioned determination of the target time point for recharging the battery based on the charging preference data and the vehicle operation data includes: adjusting the preset interval duration based on the charging preference data and the vehicle operation data to obtain the target interval duration after the adjustment; determining the target time point for recharging the battery based on the target interval duration and the first time point, the first time point being the time point when the vehicle was last parked or the time point when the battery was last recharged.

[0010] Based on the above technical means, the present application can pre-set the preset interval duration for battery recharges. Based on charging preference data and vehicle operation data, the preset interval duration can be adjusted to obtain the adjusted target interval duration. In this way, based on the charging preference data and vehicle operation data, the time interval after which the battery recharge is required can be accurately determined. Based on the last time the vehicle was parked or the last time the battery was recharged, the target time for the next battery recharge can be accurately determined.

[0011] In a possible embodiment, the charging preference data includes at least one of the following: charging interval duration, charging time, and the state of charge of the power battery when charging starts, and the vehicle operation data includes at least one of the following: vehicle usage frequency, mileage, and driving time; the above-mentioned adjusting the preset interval duration based on the charging preference data and the vehicle operation data to obtain the target interval duration after the adjustment includes: dividing the preset interval duration based on the weight parameters corresponding to the charging preference data and the vehicle operation data, and determining the first interval duration corresponding to the charging preference data and the second interval duration corresponding to the vehicle operation data; adjusting the first interval duration based on the charging interval duration, the charging time, and the state of charge of the power battery when charging starts; adjusting the second interval duration based on the vehicle usage frequency, mileage, and driving time; and obtaining the target interval duration after the adjustment based on the first interval duration and the second interval duration.

[0012] According to the above technical means, since different data have different degrees of influence on the battery charging interval, the present application determines weight parameters corresponding to the charging preference data and vehicle operation data, respectively, based on the degree of influence of the charging preference data and vehicle operation data on the battery charging interval. The preset interval durations are then divided based on the weight parameters, and a first interval duration affected by the charging preference data and a second interval duration affected by the vehicle operation data are determined separately. In this way, by adjusting the corresponding first interval duration based on the charging preference data and adjusting the second interval duration based on the vehicle operation data, the target interval duration after the adjustments can be accurately obtained.

[0013] In a possible implementation, the above-mentioned adjustment of the first interval duration based on the charging interval duration, the charging duration, and the state of charge of the power battery at the start of charging includes: reducing the first interval duration when the charging interval duration is greater than the first preset duration, the charging duration is less than the second preset duration, and the state of charge of the power battery at the start of charging is less than the first preset state of charge; or increasing the first interval duration when the charging interval duration is less than the first preset duration, the charging duration is greater than the second preset duration, and the state of charge of the power battery at the start of charging is greater than the first preset state of charge.

[0014] According to the above technical approach, when the charging interval is long, it can be assumed that the user uses the vehicle less frequently, resulting in the vehicle being powered off for extended periods of time, and thus the battery's remaining charge being low. Therefore, the recharging interval needs to be shortened to allow the battery to be recharged in a timely manner. Furthermore, when the charging interval is short, it indicates that the power battery is not fully charged and the battery cannot be fully charged. Therefore, the recharging interval needs to be shortened to allow the battery to be recharged in a timely manner. Furthermore, when the power battery's state of charge is low at the start of charging, there may be situations where the battery cannot be recharged due to the low remaining charge of the power battery. In this case, the battery has not been recharged for an extended period of time, so the recharging interval needs to be shortened to allow the battery to be recharged in a timely manner. Similarly, in the opposite situation, it indicates that the battery's remaining charge is sufficient, and the recharging interval can be increased. Thus, by appropriately adjusting the recharging interval, the timing for recharging the battery can be accurately determined.

[0015] In one possible implementation, the above-mentioned adjustment of the second interval duration based on the vehicle usage frequency, mileage, and driving duration includes: reducing the second interval duration when the vehicle usage frequency is less than a preset frequency, the mileage is less than a preset mileage, and the driving duration is less than a third preset duration; or increasing the second interval duration when the vehicle usage frequency is greater than the preset frequency, the mileage is greater than the preset mileage, and the driving duration is greater than the third preset duration.

[0016] According to the above technical means, if the vehicle is used less frequently, has a short mileage, or has been driven for a short period of time, it can be considered that the vehicle has been in a powered-off state for a long period of time, resulting in a low battery remaining charge. Therefore, the recharging interval needs to be shortened to timely recharge the battery. Similarly, in the opposite situation, if the vehicle has been powered-on for a long period of time, and the battery can be recharged in real time during the powered-on state, it can be considered that the battery remaining charge is sufficient, so the recharging interval can be increased. In this way, by reasonably adjusting the battery recharging interval, the time point for recharging the battery can be accurately determined.

[0017] In one possible embodiment, the battery charging method further includes: obtaining battery status data and environmental data, the battery status data including at least one of the following: battery state of charge, battery health status, and the environmental data including at least one of the following: ambient temperature, ambient humidity; and determining a target time point for charging the battery based on charging preference data and vehicle operation data, including: determining a target time point for charging the battery based on charging preference data, vehicle operation data, battery status data, and environmental data.

[0018] Based on the above technical means, the present application can further determine the target time point for recharging the battery based on the user's charging preference data for the vehicle and the vehicle operation data, combined with the battery status data and environmental data, so as to recharge the battery at the target time point. In this way, based on the battery status data and environmental data, the battery's power consumption rate can be determined, thereby determining when the remaining power of the battery will be depleted to the point where recharging is required, and thus accurately determining the target time point for the next battery recharge.

[0019] In one possible embodiment, the battery charging method further includes: determining whether the vehicle has been charged and / or driven within a target historical time period based on charging preference data and vehicle operation data; and issuing a prompt message if it is determined that the vehicle has not been charged and / or driven within the target historical time period, the prompt message being used to prompt the user whether to charge the vehicle.

[0020] Based on the above technical means, the present application can determine the remaining power of the power battery by determining whether the vehicle was charged and / or driven within the target historical time period, and then issue a prompt message based on the remaining power battery to prompt the user whether to charge the vehicle. In this way, the user can be prompted to charge the vehicle in a timely manner to prevent the power battery from being unable to recharge the storage battery, resulting in a low remaining battery power.

[0021] In one possible implementation, the battery charging method further includes: determining the user's acceptance of the prompt information based on the user's operation results on the prompt information, the operation results including: confirming charging, prohibiting charging, and not displaying the prompt information; and determining whether to turn off the function of sending the prompt information based on the acceptance level.

[0022] Based on the above technical means, the present application can determine the user's acceptance of the prompt information based on the user's operation results on the prompt information, thereby judging whether the user wishes to continue receiving the prompt information and thus determining whether to disable the function of sending prompt information. In this way, it can be determined whether to continue sending prompt information based on the user's operation on the prompt information, thereby improving the user experience.

[0023] In a possible embodiment, the above-mentioned issuance of a prompt message includes: obtaining pre-set reminder setting parameters, the reminder setting parameters include at least one of the following: reminder time period, reminder method, reminder method includes: sending a prompt message to a mobile terminal, sending a prompt message by voice on the vehicle computer; issuing a prompt message based on the reminder setting parameters.

[0024] According to the above technical means, the present application can determine when and in what manner to send reminder information according to pre-set reminder setting parameters, thereby improving the diversity and flexibility of sending reminder information.

[0050] In order to enable ordinary people in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0051] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects and are not used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0052] Currently, when a vehicle is not used for an extended period and the user forgets to charge it, some devices (such as the parking sensor) may still consume battery power even when the vehicle is powered off, causing the battery charge to be low. Failure to recharge the battery promptly can shorten its lifespan or affect the vehicle's usability. Therefore, dynamically adjusting the battery recharging strategy based on user habits and the vehicle's actual condition has become a pressing issue.

[0053] The battery charging method provided in the embodiment of the present application can be applied to the battery charging system. Figure 1 As shown, the battery charging system includes: a controller 11, a power battery 12 and a battery 13.

[0054] The controller 11 may be a vehicle control unit (VCU), a battery management system (BMS), or the like.

[0055] The controller 11 is used to obtain the user's charging preference data for the vehicle and the vehicle operation data.

[0056] The controller 11 is further configured to determine a target time point for charging the storage battery 13 via the power battery 12 based on the charging preference data and the vehicle operation data.

[0057] The controller 11 is further configured to recharge the battery 13 at a target time point.

[0058] For ease of understanding, the battery charging method provided by this application is specifically introduced below with reference to the accompanying drawings. The battery charging method is applied to a dual battery charger in a battery charging system, such as Figure 2 As shown, the battery charging method includes S201-S203:

[0059] S201: Obtain user's vehicle charging preference data and vehicle operation data.

[0060] In some embodiments, the charging preference data includes at least one of the following: charging interval duration, charging time, and the state of charge of the power battery when charging starts; and the vehicle operation data includes at least one of the following: vehicle usage frequency, mileage, and driving time.

[0061] In one possible implementation, the vehicle's charging preference data and vehicle operation data over a historical period can be collected through the vehicle's computer and cloud server. For example, information such as the number of times (frequency) a user uses the vehicle, the specific time of each use, the mileage and driving duration of each use, etc. can be collected. Furthermore, data on the user's vehicle charging over a historical period can be collected, such as the time of each charge, the charging duration of each charge, the charging interval between two adjacent charges, the charging location, and charging setting parameters (such as the scheduled charging time).

[0062] In one possible implementation, data preprocessing and standardization can be performed on the user's charging preference data and vehicle operation data acquired during the historical time period. Preprocessing and standardizing the collected multi-source data can ensure comparability and consistency between the various data sources.

[0063] In one possible implementation, based on the acquired user's charging preference data and vehicle operation data, the number of times the vehicle was used (frequency), daily mileage, driving time, and other data within a historical time period can be determined.

[0064] Specifically, the vehicle's scheduled charging time and the user's vehicle settings (such as charging time period preferences, reminder frequency, etc.) can be collected through the vehicle controller (such as the vehicle controller) to provide the user's charging preference data for the vehicle and the vehicle's basic status information (such as the remaining battery power, etc.).

[0065] Specifically, the navigation and positioning system can collect information such as mileage, driving time, and current location of each time a user uses the vehicle. This can be used to analyze the user's driving behavior and vehicle usage frequency, thereby further optimizing the battery charging strategy.

[0066] In one possible implementation, all acquired data information may be aggregated and transmitted to a vehicle controller, which then integrates the collected charging preference data, vehicle operation data, environmental data, and battery status data.

[0067] S202: Determine a target time point for recharging the battery based on the charging preference data and the vehicle operation data.

[0068] S203: Recharge the battery at the target time.

[0069] In one possible implementation, data analysis can be performed on the charging preference data and the vehicle operation data, so as to determine when the user will charge the vehicle or when the user will use the vehicle based on the charging preference data and the vehicle operation data, thereby determining whether the battery needs to be recharged before charging the vehicle or using the vehicle, and determining when it is more appropriate to recharge the battery.

[0070] For example, based on charging preference data and vehicle operation data, it can be determined that the user will use the vehicle in 20 hours, or charge the vehicle in 30 hours. However, the current remaining battery charge is 80%, and after 10 hours, the remaining battery charge will drop to 60%. If the battery is not recharged, the battery charge will be low, affecting the battery life or the use of the vehicle. Therefore, it can be determined that the battery needs to be recharged using the power battery after 10 hours.

[0071] In an embodiment of the present application, a target time for battery recharging is determined based on a user's charging preference data and vehicle operation data, thereby recharging the battery at the target time. This data can be used to determine the user's charging habits, such as when to charge, how long to charge, whether to charge only when the battery is depleted, and whether to fully charge the battery. Furthermore, the vehicle operation data can be used to determine the user's vehicle usage habits, such as how often the vehicle is used, how far each trip is made, and how long each trip takes. Furthermore, the battery's status, such as its remaining charge or recharging status, can be assessed based on the user's charging preference data and vehicle operation data. This allows the target time for the next battery recharging to be determined, allowing the battery to be recharged at the target time. This can improve the effectiveness of battery recharging based on the user's charging preference data and vehicle operation data, ensuring timely recharging and avoiding low battery sound levels that could affect battery life or vehicle usage.

[0072] In some embodiments, as Figure 3 As shown, the above S202 may specifically include S301-S302:

[0073] S301 : Based on the charging preference data and the vehicle operation data, adjust the preset interval duration to obtain a target interval duration after the adjustment.

[0074] In one possible implementation, the preset interval length can be initially set based on user charging preference data for the vehicle over a historical period. Alternatively, the preset interval length can be determined based on data such as the preset charging interval length, charging time, the power battery state of charge at the start of charging, vehicle usage frequency, mileage, and driving time.

[0075] In one possible implementation, when the charging preference data and vehicle operation data change, the preset interval duration can be dynamically adjusted based on the changes in the charging preference data and vehicle operation data, thereby dynamically determining the target interval duration for recharging the battery at the current moment.

[0076] In one possible implementation, the preset interval duration may be sent to the user via a vehicle-related application, allowing the user to select or adjust the preset interval duration. If the user does not adjust the preset interval duration, the battery recharging time is automatically controlled based on the determined preset interval duration.

[0077] S302: Determine a target time point for recharging the battery based on the target interval duration and the first time point.

[0078] The first time point is the time point when the vehicle is last parked or the time point when the battery is last charged.

[0079] It should be noted that while the vehicle is running, the battery is recharged in real time. Therefore, when the vehicle stops, the battery is fully charged; or after the battery is recharged, the battery is still fully charged. Therefore, the target time for the next battery recharge can be determined based on the time when the vehicle was last parked or the time when the battery was last recharged.

[0080] In an embodiment of the present application, a preset interval duration for battery recharges can be pre-set. Based on charging preference data and vehicle operating data, the preset interval duration can be adjusted to obtain a target interval duration after the adjustment. In this way, based on the charging preference data and vehicle operating data, the time interval after which the battery recharge is required can be accurately determined. Consequently, based on the last time the vehicle was parked or the last time the battery was recharged, the target time for the next battery recharge can be accurately determined.

[0081] In some embodiments, as Figure 4 As shown, the above S301 may specifically include S401-S404:

[0082] S401 : Based on weight parameters corresponding to the charging preference data and the vehicle operation data, the preset interval durations are divided to determine a first interval duration corresponding to the charging preference data and a second interval duration corresponding to the vehicle operation data.

[0083] In one possible implementation, a weight parameter corresponding to each data can be set according to the importance of each data, that is, the degree of influence of each data on the preset interval duration is determined, thereby converting it into determining the portion of the preset interval duration that each data will affect.

[0084] For example, the charging preference data, including charging interval duration, charging duration, and the state of charge of the power battery at the start of charging, have a significant impact on the preset interval duration. Therefore, the value of the charging preference data needs to be given priority. Therefore, the weight parameter corresponding to the charging preference data can be set to A%. Meanwhile, the vehicle operation data, including vehicle usage frequency, mileage, and driving duration, have a smaller impact on the preset interval duration. Therefore, the weight parameter corresponding to the vehicle operation data can be set to B% (where B is less than A). This is because a high vehicle usage frequency means a high number of battery charges and a low likelihood of battery recharge. The battery itself has a certain amount of power and does not require recharging. Therefore, the usage frequency has a smaller impact on battery recharge, and a smaller weight parameter can be set.

[0085] It is understood that data that directly affects the battery status and charge / discharge capacity can be appropriately weighted higher. That is, the weight parameter corresponding to data that helps increase battery charging is higher than the weight parameter corresponding to data that has a negative impact on the battery.

[0086] S402: Adjust the first interval duration based on the charging interval duration, the charging duration, and the state of charge of the power battery when charging starts.

[0087] In some embodiments, the above S402 may specifically include: reducing the first interval duration when the charging interval duration is greater than the first preset duration, the charging duration is less than the second preset duration, and the state of charge of the power battery when charging starts is less than the first preset state of charge.

[0088] It is understood that the longer the interval between two adjacent charges, the shorter the single charge time, and the lower the state of charge of the power battery at the start of charging, the earlier the target time point for the next charge will be determined (i.e., the preset interval time needs to be shortened). Therefore, the corresponding first interval time can be reduced.

[0089] In some embodiments, the above S402 may specifically include: increasing the first interval duration when the charging interval duration is less than the first preset duration, the charging duration is greater than the second preset duration, and the state of charge of the power battery when charging starts is greater than the first preset state of charge.

[0090] It is understood that the shorter the interval between two adjacent charges, the longer the single charge time, and the greater the state of charge of the power battery at the start of charging, the later the target time point for the next charge will be (i.e., the preset interval time needs to be increased). Therefore, the corresponding first interval time can be increased.

[0091] In the embodiments of the present application, when the charging interval is long, it can be assumed that the user uses the vehicle less frequently, resulting in the vehicle being powered off for extended periods of time, and thus the battery's remaining charge being low. Therefore, the recharging interval needs to be shortened to allow the battery to be recharged in a timely manner. Furthermore, when the charging interval is short, it indicates that the power battery is not fully charged and cannot be fully recharged. Therefore, the recharging interval needs to be shortened to allow the battery to be recharged in a timely manner. Furthermore, when the power battery's state of charge is low at the start of charging, the battery may not be recharged due to its low remaining charge. In this case, the battery's charge has been low due to a long period of inactivity, so the recharging interval needs to be shortened to allow the battery to be recharged in a timely manner. Similarly, in the opposite case, it indicates that the battery's remaining charge is sufficient, and the recharging interval can be increased. Thus, by appropriately adjusting the recharging interval, the timing for recharging the battery can be accurately determined.

[0092] S403: Adjust the second interval duration based on the vehicle usage frequency, mileage, and driving duration.

[0093] In some embodiments, the above S403 may specifically include: reducing the second interval duration when the vehicle usage frequency is less than a preset frequency, the mileage is less than a preset mileage, and the driving time is less than a third preset time.

[0094] It is understood that the lower the vehicle usage frequency, the smaller the mileage, and the shorter the driving time, the earlier the target time point for the next charge will be determined (i.e., the preset interval time needs to be shortened). Therefore, the corresponding second interval time can be reduced.

[0095] In some embodiments, the above S403 may specifically include: increasing the second interval duration when the vehicle usage frequency is greater than a preset frequency, the mileage is greater than a preset mileage, and the driving time is greater than a third preset time.

[0096] It is understood that the higher the vehicle usage frequency, the greater the mileage, and the longer the driving time, the later the target time point for the next charge will be (i.e., the preset interval time needs to be increased). Therefore, the corresponding second interval time can be increased.

[0097] In the embodiments of the present application, if the vehicle is used less frequently, has a shorter mileage, or has a shorter driving duration, it can be considered that the vehicle is in an off-power state for a prolonged period, resulting in a low battery remaining charge. Therefore, the recharging interval needs to be shortened to allow the battery to be recharged in a timely manner. Similarly, in the opposite situation, if the vehicle is in an on-power state for a prolonged period, and the battery can be recharged in real time while powered on, this indicates that the battery remaining charge is sufficient, and the recharging interval can be increased. Thus, by properly adjusting the recharging interval, the time point for recharging the battery can be accurately determined.

[0098] S404: Obtain an adjusted target interval duration based on the adjusted first interval duration and the adjusted second interval duration.

[0099] Based on this, by determining the partial interval duration corresponding to each data type, the adjusted target interval duration can be determined. Specifically, by adjusting the first interval duration corresponding to the charging preference data and the second interval duration corresponding to the vehicle operation data, and then summing the adjusted first and second interval durations, the adjusted target interval duration can be obtained.

[0100] In the embodiments of the present application, since different data have different degrees of influence on the battery charging interval, the present application determines weight parameters corresponding to the charging preference data and vehicle operation data, respectively, based on the degree of influence of the charging preference data and vehicle operation data on the battery charging interval. Thus, the preset interval durations are divided based on the weight parameters, and the first interval duration affected by the charging preference data and the second interval duration affected by the vehicle operation data are determined separately. In this way, by adjusting the corresponding first interval duration based on the charging preference data and adjusting the second interval duration based on the vehicle operation data, the target interval duration after the adjustment can be accurately obtained.

[0101] In some embodiments, as Figure 5 As shown, the battery charging method may further include S501, and the above S202 may specifically include S502:

[0102] S501: Acquire battery status data and environmental data.

[0103] The battery status data includes at least one of the following: battery state of charge and battery health status; and the environmental data includes at least one of the following: ambient temperature and ambient humidity.

[0104] In one possible implementation, since the battery's state of charge and health directly affect whether or not immediate recharging is necessary, the battery's status data has the greatest impact on the preset interval duration. Therefore, the weight parameter corresponding to the battery's status data can be set to C% (C is greater than A and B). Extreme ambient temperature and humidity can also affect battery performance, so the weight parameter corresponding to the environmental data can be set to D% (for example, D is less than C).

[0105] For example, Figure 6 As shown, the vehicle's scheduled charging time and user settings for the vehicle (such as charging time period preferences, reminder frequency, etc.) can be collected through the vehicle controller; the user's preferred reminder time period, reminder method, and feedback on the reminder information can be collected through the remote controller; the ambient temperature, ambient humidity, and other data can be collected through the thermal management controller; the mileage, driving time, and current location information of each time the user uses the vehicle can be collected through the navigation and positioning system; the power battery data (state of charge, etc.) can be collected through the battery management system; and the battery status data (state of charge, voltage, current, etc.) can be collected through the battery sensor. Based on all the collected data, processing is performed in the vehicle controller.

[0106] S502 : Determine a target time point for recharging the battery based on the charging preference data, the vehicle operation data, the battery status data, and the environmental data.

[0107] In this way, by integrating all factors (i.e., charging preference data, vehicle operation data, battery status data, and environmental data), based on the fusion of weight parameters and various data, and through weighted summation, comprehensively considering charging preference data, vehicle operation data, battery status data, and environmental data, the target time point for recharging the battery can be comprehensively determined.

[0108] In one possible implementation, the greater the battery's state of charge, the later the target time point is determined (i.e., the preset interval duration is increased); when the battery's state of charge is smaller or the battery's health status is smaller, the target time point is determined earlier (i.e., the preset interval duration is reduced).

[0109] In one possible implementation, the lower the ambient temperature (below a certain temperature, for example, below 5 degrees), or the higher the ambient temperature (above a certain temperature, for example, above 40 degrees), the earlier the target time point is determined (i.e., the preset interval duration is reduced); and when the ambient temperature is at normal temperature (for example, in the range of 5 to 40 degrees), there is no need to adjust the preset interval duration, and the target time point is determined directly according to the preset interval duration.

[0110] In one possible implementation, when the power battery's state of charge is higher, the vehicle's available power is higher, and the battery's charging capability is better, so the battery recharge interval can be appropriately shortened. On the other hand, when the power battery's state of charge is lower, the vehicle's available power is lower, and the battery's charging capability is worse, so the battery recharge interval can be appropriately increased.

[0111] In an embodiment of the present application, the present application can further determine a target time point for recharging the battery based on the user's charging preference data for the vehicle and the vehicle operation data, combined with the battery status data and environmental data, so that the battery can be recharged at the target time point. In this way, based on the battery status data and environmental data, the battery's power consumption rate can be determined, thereby determining when the remaining power of the battery will be depleted to the point where recharging is required, thereby accurately determining the target time point for the next battery recharge.

[0112] In some embodiments, the battery charging method may further include: determining whether the vehicle has been charged and / or driven within a target historical time period based on charging preference data and vehicle operation data; and issuing a prompt message if it is determined that the vehicle has not been charged and / or driven within the target historical time period, the prompt message being used to prompt the user whether to charge the vehicle.

[0113] In one possible implementation, when the vehicle is not charged and / or driven during the same time period every day, or after a certain time period, it is determined that the vehicle is not used or charged, and the remaining battery power is low at this time, a prompt message can be issued to prompt the user whether to charge the vehicle.

[0114] In an embodiment of the present application, the present application can determine the remaining power of the power battery by determining whether the vehicle was charged and / or driven within a target historical time period, and then issue a prompt based on the remaining power battery to prompt the user whether to charge the vehicle. In this way, the user can be prompted to charge the vehicle in a timely manner to prevent the power battery from being unable to recharge the storage battery, resulting in a low remaining battery power.

[0115] In some embodiments, issuing a prompt message includes: obtaining pre-set reminder setting parameters, the reminder setting parameters include at least one of the following: reminder time period, reminder method, reminder method includes: sending a prompt message to a mobile terminal, sending a prompt message by voice by the vehicle computer; issuing a prompt message based on the reminder setting parameters.

[0116] Specifically, the remote controller can collect the user's preferred reminder time period and reminder method (such as mobile terminal notification, voice reminder, etc.), and record the user's feedback on the reminder information (such as whether the user confirms charging, charging location preference, etc.), providing a basis for personalized reminder strategies.

[0117] In the embodiment of the present application, the present application can determine when and in what manner to send a reminder message based on pre-set reminder setting parameters, thereby improving the diversity and flexibility of sending reminder messages.

[0118] In some embodiments, the battery charging method may further include: determining the user's acceptance of the prompt information based on the user's operation results on the prompt information, the operation results including: confirming charging, prohibiting charging, and not displaying the prompt information; based on the acceptance level, determining whether to turn off the function of issuing the prompt information.

[0119] For example, Figure 7 As shown, when it is determined that the battery needs to be recharged, a prompt message can be sent to a mobile terminal or the vehicle computer via voice. After the user operates the prompt message, the user's acceptance of the prompt message can be determined based on the user's operation results. Then, it is determined whether to disable or adjust the function of issuing prompt messages (for example, changing the prompt content, adjusting the reminder time period, reminder method, etc.). After the user decides to recharge the battery, the next time point for recharging the battery can be further determined, and the battery can be detected in real time to determine whether it needs to be recharged.

[0120] This allows the vehicle to provide user reminders via the vehicle computer and remotely, while avoiding reminders during busy or inconvenient times, thus reducing the user's burden. However, the method and time of reminders may still cause user dissatisfaction. Therefore, based on user feedback, the reminder policy can be adjusted to determine whether to continue sending reminders to meet the user's actual needs.

[0121] In an embodiment of the present application, the present application can determine the user's acceptance of the prompt information based on the user's operation results on the prompt information, thereby judging whether the user wishes to continue receiving the prompt information and thus determining whether to disable the function of sending prompt information. In this way, it is possible to determine whether to continue sending prompt information based on the user's operation on the prompt information, thereby improving the user's user experience.
