Description

Technical Field

[0001] This invention belongs to the field of service station recommendation technology, and particularly relates to a method, system, electronic device and medium for providing charging and battery swapping reminders for electric vehicles. Background Technology

[0002] Electric vehicles require charging or battery swapping during use. To conveniently remind users to charge / swap batteries in a timely manner, most electric vehicles detect the remaining battery charge and prompt the user to charge / swap the battery when the remaining charge falls below a preset value. This method of prompting is based solely on a fixed preset value, resulting in poor flexibility, low accuracy, and a subpar user experience. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing electric vehicle charging and swapping prompts, which are based solely on the remaining power and have low accuracy and poor user experience. The present invention provides an electric vehicle charging and swapping prompt method, system, electronic device and medium.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] This invention provides a method for providing charging and battery swapping reminders for electric vehicles, comprising the following steps:

[0006] To obtain the remaining range of an electric vehicle, the remaining range is the distance that the remaining charge of the electric vehicle's battery pack can support for the electric vehicle to travel.

[0007] If the remaining mileage is determined to be less than the first preset mileage value, then alternative service stations are obtained. The alternative service stations are service stations whose travel path length is less than or equal to the remaining mileage. The travel path is the path from the electric vehicle to the service station. The service stations include one or more of the following: charging stations, battery swapping stations, and charging / battery swapping stations.

[0008] Charge / battery swapping reminders are generated based on the number of available service stations.

[0009] In this solution, when the remaining mileage corresponding to the battery pack is less than the first preset mileage value, alternative service stations are obtained, and charging / battery swapping prompts are generated based on the number of alternative service stations. The remaining mileage corresponding to the battery pack and the distribution of service stations are combined to obtain the number of alternative service stations, which serves as the basis for generating charging / battery swapping prompts, thus improving the accuracy of charging / battery swapping prompts.

[0010] Preferably, charging and battery swapping reminders are generated based on the number of alternative service stations, specifically including:

[0011] If the number of alternative service stations is determined to be 1, a charging / battery swapping prompt message will be generated, and the alternative service station will be selected as the target service station to generate the corresponding charging / battery swapping prompt message.

[0012] In this solution, the number of alternative service stations within the range corresponding to the remaining mileage of the electric vehicle is equal to 1. This indicates that, considering the remaining mileage of the electric vehicle and the distribution of service stations, the charging and battery swapping needs of the electric vehicle are very urgent. Therefore, charging and battery swapping prompts are generated to remind users to charge or swap batteries. Moreover, the alternative service station is used as the target service station to provide users with clear prompts so that users have a clear destination and can carry out charging and battery swapping operations in a timely manner.

[0013] Preferably, charging and battery swapping reminders are generated based on the number of alternative service stations, specifically including:

[0014] If the number of alternative service stations is greater than 1, and the length of the travel path corresponding to each alternative service station is greater than the second preset mileage value, then the alternative service station with the shortest waiting time is selected as the target service station to generate the corresponding charging and battery swapping prompt information. The second preset mileage value is less than the first preset mileage value, and the waiting time is the time interval between the current time and the expected time for the electric vehicle to complete the battery swap at the alternative service station.

[0015] In this solution, in addition to obtaining a relatively broad range of alternative service stations based on the first preset mileage value, the distribution of alternative service stations is also evaluated based on a smaller range corresponding to the second preset mileage value. If the number of alternative service stations is greater than one, and the length of the travel path corresponding to each alternative service station is greater than the second preset mileage value, meaning that although there is more than one alternative service station within the range corresponding to the first preset mileage value, these alternative service stations are all located outside the range corresponding to the second preset mileage value, it can be assessed that although the current remaining battery power of the electric vehicle is not in the most urgent situation, it is not optimistic. Therefore, the alternative service station with the shortest waiting time is determined as the target service station to generate corresponding charging and battery swapping prompt information, so that users can clearly understand the destination of receiving charging and battery swapping services and perform charging and battery swapping operations in a timely manner.

[0016] Preferably, charging and battery swapping reminders are generated based on the number of alternative service stations, specifically including:

[0017] If the number of alternative service stations is greater than 1, and the length of the travel path corresponding to at least one alternative service station is less than or equal to the second preset mileage value, then after the electric vehicle continues to travel a third preset mileage value, alternative service stations are obtained again, and charging / battery swapping prompt information is generated based on the number of alternative service stations obtained again, wherein the second preset mileage value is less than the first preset mileage value, and the third preset mileage value is less than the second preset mileage value.

[0018] In this solution, in addition to obtaining alternative service stations within a relatively broad range based on the first preset mileage value, the distribution of alternative service stations is also evaluated within a smaller range corresponding to the second preset mileage value. It is determined that the number of alternative service stations is greater than one, and the length of the travel path corresponding to at least one alternative service station is less than or equal to the second preset mileage value. This means that there is more than one alternative service station within the range corresponding to the first preset mileage value, and alternative service stations still exist within the range corresponding to the second preset mileage value. In this case, although the remaining battery power of the electric vehicle is low (remaining range is less than the first preset mileage value), because alternative service stations still exist within the range corresponding to the second preset mileage value, the remaining battery power is not critical and can continue to be used, considering both the remaining range and the distribution of alternative service stations. After the electric vehicle continues to travel a third preset mileage value, new alternative service stations are obtained again based on the new location of the electric vehicle, and charging / swapping reminder information is generated based on the number of new alternative service stations. This ensures full utilization of battery power and reduces waste.

[0019] Preferably, charging and battery swapping reminders are generated based on the number of alternative service stations, specifically including:

[0020] If the number of alternative service stations is greater than 1, and the length of the travel path corresponding to each alternative service station is greater than the second preset mileage value, then the alternative service station with the shortest waiting time is selected as the target service station to generate the corresponding charging and battery swapping prompt information. The second preset mileage value is less than the first preset mileage value, and the waiting time is the time interval between the expected time for the electric vehicle to arrive at the alternative service station and the expected time for the electric vehicle to complete the battery swapping at the alternative service station.

[0021] In this solution, in addition to obtaining a relatively broad range of alternative service stations based on the first preset mileage value, the distribution of alternative service stations is also evaluated based on a smaller range corresponding to the second preset mileage value. If the number of alternative service stations is greater than one, and the length of the travel path corresponding to each alternative service station is greater than the second preset mileage value, meaning that although there is more than one alternative service station within the range corresponding to the first preset mileage value, these alternative service stations are all located outside the range corresponding to the second preset mileage value, it can be assessed that although the current remaining battery power of the electric vehicle is not in the most urgent situation, it is not optimistic. Therefore, the alternative service station with the shortest waiting time is determined as the target service station to generate corresponding charging and battery swapping prompt information, so that users can clearly understand the destination of receiving charging and battery swapping services and perform charging and battery swapping operations in a timely manner.

[0022] Preferably, alternative service sites include:

[0023] Obtain the current first location of the electric vehicle. Based on the first location and the second location of the optional service station, obtain the route for the electric vehicle to reach the optional service station. If the length of the route is less than or equal to the remaining mileage, then the optional service station is determined as a candidate service station. The optional service station is a service station within a preset area around the electric vehicle.

[0024] In this solution, the route from the electric vehicle to the available service station is obtained based on the electric vehicle's current location and the location of the available service station. The alternative service station is determined based on the length of the route, which can improve the accuracy of obtaining alternative service stations.

[0025] Ideally, the route should be the shortest path for the electric vehicle to reach the service station.

[0026] In this scheme, when there are several paths from the current location of an electric vehicle to the location of an optional service station, the shortest path is used as the travel route to determine the alternative service station, which can improve the efficiency and accuracy of obtaining alternative service stations.

[0027] Preferably, it also includes:

[0028] After generating charging and battery swapping prompts based on the number of alternative service stations, the process also includes: obtaining the user's confirmed charging and battery swapping instructions, and generating navigation information for the electric vehicle to the target service station based on preset map data.

[0029] In this solution, navigation information from electric vehicles to the target service station is generated, which can guide users to the target service station and improve efficiency.

[0030] Preferably, the remaining range of the electric vehicle is obtained, specifically including:

[0031] Obtain the battery pack's SOC (State of Charge) and calculate the remaining range based on the SOC. The remaining range is positively correlated with the SOC.

[0032] In this solution, the remaining mileage is obtained by reading the SOC of the battery pack, and the obtained remaining mileage data is highly accurate.

[0033] Preferably, the remaining range of the electric vehicle is obtained, specifically including:

[0034] The remaining mileage is obtained from the electric vehicle's T-BOX (Telematics BOX, a remote information processor used to communicate with the back-end system / mobile application), where the T-BOX obtains the remaining mileage in real time.

[0035] In this solution, the remaining mileage is obtained in real time from the electric vehicle's T-BOX, which is highly accurate.

[0036] The present invention also provides an electric vehicle charging and swapping reminder system, including a mileage acquisition module, a backup station acquisition module, and a reminder module;

[0037] The mileage acquisition module is used to obtain the remaining mileage of the electric vehicle. The remaining mileage is the distance that the remaining power of the electric vehicle's battery pack can support for the electric vehicle to travel.

[0038] The alternative station acquisition module is used to determine if the remaining mileage is less than a first preset mileage value, and then acquire alternative service stations. The alternative service stations are service stations whose travel path length is less than or equal to the remaining mileage. The travel path is the path from the electric vehicle to the service station. The service stations include one or more of the following: charging stations, battery swapping stations, and charging / battery swapping stations.

[0039] The prompt module is used to generate charging and battery swapping prompts based on the number of alternative service stations.

[0040] In this solution, when the remaining mileage corresponding to the battery pack is less than the first preset mileage value, alternative service stations are obtained, and charging / battery swapping prompts are generated based on the number of alternative service stations. The remaining mileage corresponding to the battery pack and the distribution of service stations are combined to obtain the number of alternative service stations, which serves as the basis for generating charging / battery swapping prompts, thus improving the accuracy of charging / battery swapping prompts.

[0041] Preferably, the prompting module is used to determine that if the number of alternative service stations is equal to 1, then generate charging and battery swapping prompt information, and determine the alternative service station as the target service station to generate the corresponding charging and battery swapping prompt information.

[0042] In this solution, the number of alternative service stations within the range corresponding to the remaining mileage of the electric vehicle is equal to 1. This indicates that, considering the remaining mileage of the electric vehicle and the distribution of service stations, the charging and battery swapping needs of the electric vehicle are very urgent. Therefore, charging and battery swapping prompts are generated to remind users to charge or swap batteries. Moreover, the alternative service station is used as the target service station to provide users with clear prompts so that users have a clear destination and can carry out charging and battery swapping operations in a timely manner.

[0043] Preferably, the prompting module determines that the number of alternative service stations is greater than 1, and the length of the travel path corresponding to each alternative service station is greater than the second preset mileage value. Then, the alternative service station with the shortest waiting time is determined as the target service station to generate the corresponding charging and battery swapping prompt information. The second preset mileage value is less than the first preset mileage value, and the waiting time is the time interval between the current time and the expected time for the electric vehicle to complete the battery swap at the alternative service station.

[0044] In this solution, in addition to obtaining a relatively broad range of alternative service stations based on the first preset mileage value, the distribution of alternative service stations is also evaluated based on a smaller range corresponding to the second preset mileage value. If the number of alternative service stations is greater than one, and the length of the travel path corresponding to each alternative service station is greater than the second preset mileage value, meaning that although there is more than one alternative service station within the range corresponding to the first preset mileage value, these alternative service stations are all located outside the range corresponding to the second preset mileage value, it can be assessed that although the current remaining battery power of the electric vehicle is not in the most urgent situation, it is not optimistic. Therefore, the alternative service station with the shortest waiting time is determined as the target service station to generate corresponding charging and battery swapping prompt information, so that users can clearly understand the destination of receiving charging and battery swapping services and perform charging and battery swapping operations in a timely manner.

[0045] Preferably, the prompting module is used to determine that the number of alternative service stations is greater than 1, and the length of the travel path corresponding to at least one alternative service station is less than or equal to the second preset mileage value. Then, after the electric vehicle continues to travel a third preset mileage value, alternative service stations are obtained again, and charging and battery swapping prompt information is generated based on the number of alternative service stations obtained again. The second preset mileage value is less than the first preset mileage value, and the third preset mileage value is less than the second preset mileage value.

[0046] In this solution, in addition to obtaining alternative service stations within a relatively broad range based on the first preset mileage value, the distribution of alternative service stations is also evaluated within a smaller range corresponding to the second preset mileage value. It is determined that the number of alternative service stations is greater than one, and the length of the travel path corresponding to at least one alternative service station is less than or equal to the second preset mileage value. This means that there is more than one alternative service station within the range corresponding to the first preset mileage value, and alternative service stations still exist within the range corresponding to the second preset mileage value. In this case, although the remaining battery power of the electric vehicle is low (remaining range is less than the first preset mileage value), because alternative service stations still exist within the range corresponding to the second preset mileage value, the remaining battery power is not critical and can continue to be used, considering both the remaining range and the distribution of alternative service stations. After the electric vehicle continues to travel a third preset mileage value, new alternative service stations are obtained again based on the new location of the electric vehicle, and charging / swapping reminder information is generated based on the number of new alternative service stations. This ensures full utilization of battery power and reduces waste.

[0047] Preferably, the prompting module determines that the number of alternative service stations is greater than 1, and the length of the travel path corresponding to each alternative service station is greater than the second preset mileage value. Then, the alternative service station with the shortest waiting time is determined as the target service station to generate the corresponding charging and battery swapping prompt information. The second preset mileage value is less than the first preset mileage value, and the waiting time is the time interval between the expected time for the electric vehicle to arrive at the alternative service station and the expected time for the electric vehicle to complete the battery swapping at the alternative service station.

[0048] In this solution, in addition to obtaining a relatively broad range of alternative service stations based on the first preset mileage value, the distribution of alternative service stations is also evaluated based on a smaller range corresponding to the second preset mileage value. If the number of alternative service stations is greater than one, and the length of the travel path corresponding to each alternative service station is greater than the second preset mileage value, meaning that although there is more than one alternative service station within the range corresponding to the first preset mileage value, these alternative service stations are all located outside the range corresponding to the second preset mileage value, it can be assessed that although the current remaining battery power of the electric vehicle is not in the most urgent situation, it is not optimistic. Therefore, the alternative service station with the shortest waiting time is determined as the target service station to generate corresponding charging and battery swapping prompt information, so that users can clearly understand the destination of receiving charging and battery swapping services and perform charging and battery swapping operations in a timely manner.

[0049] Preferably, the alternative station acquisition module is used to acquire the first location of the electric vehicle, acquire the route of the electric vehicle to the alternative service station based on the first location and the second location of the alternative service station, and determine that the length of the route is less than or equal to the remaining mileage, then the alternative service station is determined as the alternative service station. The alternative service station is a service station in a preset area around the electric vehicle.

[0050] In this solution, the route from the electric vehicle to the available service station is obtained based on the electric vehicle's current location and the location of the available service station. The alternative service station is determined based on the length of the route, which can improve the accuracy of obtaining alternative service stations.

[0051] Ideally, the route should be the shortest path for the electric vehicle to reach the service station.

[0052] In this scheme, when there are several paths from the current location of an electric vehicle to the location of an optional service station, the shortest path is used as the travel route to determine the alternative service station, which can improve the efficiency and accuracy of obtaining alternative service stations.

[0053] Preferably, it also includes a navigation module;

[0054] After the prompting module generates charging and battery swapping prompts based on the number of alternative service stations, the navigation module obtains the user's confirmation of the charging and battery swapping command and generates navigation information from the electric vehicle to the target service station based on preset map data.

[0055] In this solution, navigation information from electric vehicles to the target service station is generated, which can guide users to the target service station and improve efficiency.

[0056] Preferably, the mileage acquisition module is used to acquire the state of charge (SOC) of the battery pack and obtain the remaining mileage based on the SOC, wherein the remaining mileage is positively correlated with the SOC.

[0057] In this solution, the remaining mileage is obtained by reading the SOC of the battery pack, and the obtained remaining mileage data is highly accurate.

[0058] Preferably, the mileage acquisition module is used to acquire the remaining mileage from the electric vehicle's T-BOX, wherein the T-BOX acquires the remaining mileage in real time.

[0059] In this solution, the remaining mileage is obtained in real time from the electric vehicle's T-BOX, which is highly accurate.

[0060] The present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the electric vehicle charging and swapping reminder method of the present invention.

[0061] The present invention also provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the electric vehicle charging and swapping reminder method of the present invention.

[0062] The positive and progressive effects of this invention are as follows: When the remaining mileage corresponding to the battery pack is less than a first preset mileage value, this invention obtains alternative service stations and generates charging and swapping prompt information based on the number of alternative service stations. The remaining mileage corresponding to the battery pack and the distribution of service stations are combined to obtain the number of alternative service stations, which serves as the basis for generating charging and swapping prompt information, thereby improving the accuracy of charging and swapping prompts and enhancing the user experience.

[0069] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0070] Example 1

[0071] This embodiment provides a method for providing charging and battery swapping reminders for electric vehicles. (Refer to...) Figure 1 The electric vehicle charging / swapping reminder method includes the following steps:

[0072] Step S1: Obtain the remaining range of the electric vehicle. The remaining range is the distance the electric vehicle can travel with the remaining charge of its battery pack.

[0073] Step S2: If the remaining mileage is less than a first preset mileage value, then obtain alternative service stations. Alternative service stations are those where the length of the travel route is less than or equal to the remaining mileage. The travel route is the path from the electric vehicle to the service station. Service stations include one or more of the following: charging stations, battery swapping stations, and charging / battery swapping stations.

[0074] Step S3: Generate charging / battery swapping prompts based on the number of alternative service stations.

[0075] The remaining mileage refers to the remaining driving range of the vehicle based on its current battery charge. Specifically, in step S1, the remaining mileage of the electric vehicle is obtained for comparison with a first preset mileage value. In some optional embodiments, the State of Charge (SOC) of the battery pack is obtained, and the remaining mileage is calculated based on the SOC, where the remaining mileage is positively correlated with the SOC. In one optional embodiment, the remaining mileage is the product of the SOC and a coefficient obtained from statistical data on the remaining mileage and SOC. In other optional embodiments, the remaining mileage is obtained from the electric vehicle's T-BOX, where the T-BOX obtains the remaining mileage in real time. In this embodiment, the T-BOX obtains the battery's SOC, and the remaining mileage is calculated from the battery's SOC using a conversion formula.

[0076] Next, in step S2, if the remaining mileage is less than a first preset mileage value, then alternative service stations are obtained. These alternative service stations are those where the length of the travel path is less than or equal to the remaining mileage, and the travel path is the route from the electric vehicle to the service station.

[0077] In specific implementation, the method for obtaining alternative service stations includes: obtaining the current first location of the electric vehicle; obtaining the travel path from the electric vehicle to the alternative service station based on the first location and the second location of the alternative service station; determining that the length of the travel path is less than or equal to the remaining mileage; and then determining the alternative service station as an alternative service station. The alternative service station is a service station within a preset area surrounding the electric vehicle. As an optional implementation, the alternative service station is a service station within a circle centered on the current first location of the electric vehicle and with a radius equal to a first preset mileage value. When there is not a unique path from the current first location of the electric vehicle to the second location of the alternative service station, the shortest path from the electric vehicle to the alternative service station is taken as the travel path.

[0078] In one optional implementation, the first preset mileage value is 100 kilometers. In other optional implementations, the first preset mileage value is obtained based on the distribution of service stations, so as to ensure that when the remaining mileage of the electric vehicle is just less than the first preset mileage, there are still alternative service stations within the range of its remaining mileage for the electric vehicle to charge or swap batteries.

[0079] After identifying the candidate service sites, the number of candidate service sites can be obtained. Further, refer to... Figure 2 In step S3, according to step S301, if the number of alternative service stations is equal to 1, then step S302 is executed to generate charging / battery swapping prompt information and determine the alternative service station as the target service station to generate the corresponding charging / battery swapping prompt information. The fact that the number of alternative service stations is equal to 1 means that, based on the current location of the electric vehicle, there is only one alternative service station within the range of its remaining battery power. This indicates that, considering the remaining range of the electric vehicle and the distribution of service stations, the charging / battery swapping need of the electric vehicle is very urgent. Therefore, charging / battery swapping prompt information is generated to remind the user to charge / swap the battery. Moreover, by using this alternative service station as the target service station, a clear prompt is provided to the user so that the user has a clear destination and can perform the charging / battery swapping operation in a timely manner.

[0080] In step S3, according to step S303, if the number of alternative service stations is greater than 1, it means that, based on the first location of the electric vehicle, there is more than one alternative service station within the driving range supported by its remaining power. This indicates that, considering the remaining range of the electric vehicle and the distribution of service stations, the charging and swapping needs of the electric vehicle have not yet reached a very urgent level.

[0081] In this case (where the number of alternative service sites is greater than 1), refer to Figure 2 The electric vehicle charging and battery swapping reminder method in this embodiment provides a more detailed reminder scheme.

[0082] On the one hand, according to step S301, if the number of alternative service stations is greater than 1, and according to step S304, if the length of the travel path corresponding to each alternative service station is greater than the second preset mileage value, then step S305 is executed to determine the alternative service station with the shortest waiting time as the target service station to generate the corresponding charging / swapping prompt information. The second preset mileage value is less than the first preset mileage value. In addition to obtaining alternative service stations from a relatively broad range based on the first preset mileage value, the distribution of alternative service stations is also evaluated based on a smaller range corresponding to the second preset mileage value. If the number of alternative service stations is greater than 1, and the length of the travel path corresponding to each alternative service station is greater than the second preset mileage value, that is, although there is more than one alternative service station within the range corresponding to the first preset mileage value, these alternative service stations are all distributed outside the range corresponding to the second preset mileage value. Therefore, it can be assessed that although the current remaining battery power of the electric vehicle is not in the most urgent situation, it is not optimistic. Therefore, the candidate service station with the shortest waiting time among the alternative service stations is identified as the target service station to generate corresponding charging and battery swapping prompts, so that users can clearly understand the destination of receiving charging and battery swapping services and carry out charging and battery swapping operations in a timely manner.

[0083] In one alternative implementation, the waiting time is the time interval between the expected time for the electric vehicle to arrive at the alternative service station and the expected time for the electric vehicle to complete the battery swap at the alternative service station.

[0084] In another alternative implementation, the waiting time is the time interval between the current time and the expected time for the electric vehicle to complete the battery swap at the alternative service station.

[0085] The time interval between the current time and the expected time for the electric vehicle to complete the battery swap at the alternative service station can be obtained from the time interval between the current estimated time for the electric vehicle to reach the alternative service station and the expected time for the electric vehicle to complete the battery swap at the alternative service station. The expected time for the electric vehicle to reach the alternative service station can be estimated based on the length of the route taken by the electric vehicle to reach the alternative service station and the corresponding road conditions.

[0086] In some alternative implementations, the time interval between the expected time for the electric vehicle to arrive at the alternative service station and the expected time for the electric vehicle to complete the battery swap at the alternative service station is estimated based on the number of vehicles currently queuing for battery swaps at the alternative service station.

[0087] Corresponding to the implementation where the first preset mileage value is 100 kilometers, the second preset mileage value is 85 kilometers. In other optional implementations, the second preset mileage value is determined according to the first preset mileage value at a first preset ratio.

[0088] On the other hand, according to step S303, if the number of candidate service stations is greater than 1, and according to step S306, the length of the travel path corresponding to at least one candidate service station is less than or equal to the second preset mileage value, then step S307 is executed. The electric vehicle continues to travel for a third preset mileage value, and then returns to step S2 to obtain candidate service stations again. Then, charging / swapping reminder information is generated based on the number of candidate service stations obtained again in step S3. Here, the second preset mileage value is less than the first preset mileage value, and the third preset mileage value is less than the second preset mileage value. That is, if the number of candidate service stations is greater than 1, and the length of the travel path corresponding to at least one candidate service station is less than or equal to the second preset mileage value, after the electric vehicle continues to travel for a third preset mileage value, candidate service stations are obtained again, and charging / swapping reminder information is generated based on the number of candidate service stations obtained again. In this case, in addition to obtaining candidate service stations from a relatively broad range based on the first preset mileage value, the distribution of candidate service stations is also evaluated based on a smaller range corresponding to the second preset mileage value. The system determines that the number of alternative service stations is greater than one, and the length of the travel path corresponding to at least one alternative service station is less than or equal to a second preset mileage value. This means that there is more than one alternative service station within the range corresponding to the first preset mileage value, and alternative service stations still exist within the range corresponding to the second preset mileage value. In this case, although the electric vehicle's remaining battery power is low (remaining range is less than the first preset mileage value), because alternative service stations still exist within the range corresponding to the second preset mileage value, the remaining battery power is not critical, and the vehicle can continue to be used. After the electric vehicle continues to travel a third preset mileage value, new alternative service stations are obtained based on the new location of the electric vehicle, and charging / swapping reminders are generated based on the number of new alternative service stations. This ensures full utilization of the battery power and reduces waste.

[0089] Corresponding to the implementation where the first preset mileage value is 100 kilometers, the third preset mileage value is 10 kilometers. In other optional implementations, the third preset mileage value is determined according to the first preset mileage value based on a second preset ratio.

[0090] according to Figure 3 In one optional implementation shown, after step S3, the electric vehicle charging / swapping reminder method further includes:

[0091] Step S4: Obtain the user's confirmed charging / battery swapping instruction, and generate navigation information for the electric vehicle to the target service station based on preset map data.

[0092] Generating navigation information from electric vehicles to the target service station can guide users to the target service station and improve efficiency.

[0093] Example 2

[0094] This embodiment provides a charging and battery swapping reminder system for electric vehicles. (Refer to...) Figure 4 The electric vehicle charging and swapping reminder system includes a mileage acquisition module 501, a backup station acquisition module 502, and a reminder module 503.

[0095] The system includes a mileage acquisition module for obtaining the remaining mileage of the electric vehicle, which is the range that the remaining battery pack power can support for the electric vehicle to travel; a backup station acquisition module for determining if the remaining mileage is less than a first preset mileage value, and then acquiring backup service stations, which are service stations whose travel path length is less than or equal to the remaining mileage, and whose travel path is the path from the electric vehicle to the service station, wherein the service station includes one or more of charging stations, battery swapping stations, and charging-battery swapping stations; and a prompt module for generating charging and battery swapping prompt information based on the number of backup service stations.

[0096] In specific implementations, the mileage acquisition module obtains the remaining mileage of the electric vehicle for comparison with a first preset mileage value. In some optional embodiments, the State of Charge (SOC) of the battery pack is obtained, and the remaining mileage is derived from the SOC, wherein the remaining mileage is positively correlated with the SOC. In one optional embodiment, the remaining mileage is the product of the SOC and a coefficient obtained based on statistical data of the remaining mileage and SOC. In other optional embodiments, the remaining mileage is obtained from the electric vehicle's T-BOX, wherein the T-BOX obtains the remaining mileage in real time.

[0097] Next, if the remaining mileage is less than a first preset mileage value, the alternative service station acquisition module acquires alternative service stations. These alternative service stations are those whose travel path length is less than or equal to the remaining mileage, and the travel path is the route from the electric vehicle to the service station.

[0098] In specific implementation, the alternative service station acquisition module acquires alternative service stations by: acquiring the current first location of the electric vehicle; acquiring the travel path from the electric vehicle to the alternative service station based on the first location and the second location of the alternative service station; determining that the length of the travel path is less than or equal to the remaining mileage; and then identifying the alternative service station as an alternative service station. The alternative service station is a service station within a preset area surrounding the electric vehicle. As an optional implementation, the alternative service station is a service station within a radius of a circle centered on the current first location of the electric vehicle and containing a first preset mileage value. When the path from the current first location of the electric vehicle to the second location of the alternative service station is not unique, the shortest path from the electric vehicle to the alternative service station is taken as the travel path.

[0099] In one optional implementation, the first preset mileage value is 100 kilometers. In other optional implementations, the first preset mileage value is obtained based on the distribution of service stations, so as to ensure that when the remaining mileage of the electric vehicle is just less than the first preset mileage, there are still alternative service stations within the range of its remaining mileage for the electric vehicle to charge or swap batteries.

[0100] After identifying alternative service stations, the number of alternative service stations can be obtained. Further, if the number of alternative service stations equals one, the prompting module generates a charging / battery swapping prompt and identifies the alternative service station as the target service station to generate the corresponding charging / battery swapping prompt. A number of alternative service stations equaling one means that, based on the electric vehicle's current location, there is only one alternative service station within the range supported by its remaining battery power. This indicates that, considering the electric vehicle's remaining range and the distribution of service stations, the need for charging / battery swapping is very urgent. Therefore, the prompting module generates a charging / battery swapping prompt to remind the user to charge / battery swap, and provides a clear prompt to the user with a clear destination so that they can perform the charging / battery swapping operation in a timely manner.

[0101] If the number of alternative service stations is greater than 1, it means that, based on the current location of the electric vehicle, there is more than one alternative service station within the range that its remaining battery power can support. This indicates that, considering the remaining range of the electric vehicle and the distribution of service stations, the charging and battery swapping needs of the electric vehicle have not yet reached a very urgent level.

[0102] In this case (the number of alternative service stations is greater than 1), the electric vehicle charging and swapping reminder system of this embodiment provides a more detailed reminder scheme.

[0103] On one hand, if the number of alternative service stations is greater than one, and the length of the travel path corresponding to each alternative service station is greater than the second preset mileage value, the prompting module determines the alternative service station with the shortest waiting time as the target service station to generate the corresponding charging / swapping prompt information. The second preset mileage value is less than the first preset mileage value. In addition to obtaining alternative service stations from a relatively broad range based on the first preset mileage value, the distribution of alternative service stations is also evaluated based on a smaller range corresponding to the second preset mileage value. If the number of alternative service stations is greater than one, and the length of the travel path corresponding to each alternative service station is greater than the second preset mileage value, that is, although there is more than one alternative service station within the range corresponding to the first preset mileage value, these alternative service stations are all distributed outside the range corresponding to the second preset mileage value. Therefore, it can be assessed that although the current remaining battery power of the electric vehicle is not in the most urgent situation, it is not optimistic. Therefore, the alternative service station with the shortest waiting time is determined as the target service station to generate the corresponding charging / swapping prompt information, so that users can clearly understand the destination of receiving charging / swapping services and perform charging / swapping operations in a timely manner.

[0104] In one alternative implementation, the waiting time is the time interval between the expected time for the electric vehicle to arrive at the alternative service station and the expected time for the electric vehicle to complete the battery swap at the alternative service station.

[0105] In another alternative implementation, the waiting time is the time interval between the current time and the expected time for the electric vehicle to complete the battery swap at the alternative service station.

[0106] The time interval between the current time and the expected time for the electric vehicle to complete the battery swap at the alternative service station can be obtained from the estimated time it takes for the electric vehicle to reach the alternative service station, and the time interval between the expected time for the electric vehicle to reach the alternative service station and the expected time for the electric vehicle to complete the battery swap at the alternative service station. The estimated time it takes for the electric vehicle to reach the alternative service station can be estimated based on the length of the route taken by the electric vehicle to reach the alternative service station and the corresponding road conditions.

[0107] In some alternative implementations, the time interval between the expected time for the electric vehicle to arrive at the alternative service station and the expected time for the electric vehicle to complete the battery swap at the alternative service station is estimated based on the number of vehicles currently queuing for battery swaps at the alternative service station.

[0108] Corresponding to the implementation where the first preset mileage value is 100 kilometers, the second preset mileage value is 85 kilometers. In other optional implementations, the second preset mileage value is determined according to the first preset mileage value at a first preset ratio.

[0109] On the other hand, if the number of alternative service stations is greater than 1, and the length of the travel path corresponding to at least one alternative service station is less than or equal to the second preset mileage value, then after the electric vehicle continues to travel a third preset mileage value, the alternative service station acquisition module acquires alternative service stations again, and then the prompting module generates charging / battery swapping prompt information based on the number of alternative service stations acquired again. Here, the second preset mileage value is less than the first preset mileage value, and the third preset mileage value is less than the second preset mileage value. That is, if the number of alternative service stations is greater than 1, and the length of the travel path corresponding to at least one alternative service station is less than or equal to the second preset mileage value, after the electric vehicle continues to travel a third preset mileage value, alternative service stations are acquired again, and charging / battery swapping prompt information is generated based on the number of alternative service stations acquired again. In this case, in addition to obtaining alternative service stations from a relatively broad range obtained from the first preset mileage value, the distribution of alternative service stations is also evaluated based on a smaller range corresponding to the second preset mileage value. The system determines that the number of alternative service stations is greater than one, and the length of the travel path corresponding to at least one alternative service station is less than or equal to a second preset mileage value. This means that there is more than one alternative service station within the range corresponding to the first preset mileage value, and alternative service stations still exist within the range corresponding to the second preset mileage value. In this case, although the electric vehicle's remaining battery power is low (remaining range is less than the first preset mileage value), because alternative service stations still exist within the range corresponding to the second preset mileage value, the remaining battery power is not critical, and the vehicle can continue to be used. After the electric vehicle continues to travel a third preset mileage value, new alternative service stations are obtained based on the new location of the electric vehicle, and charging / swapping reminders are generated based on the number of new alternative service stations. This ensures full utilization of the battery power and reduces waste.

[0110] Corresponding to the implementation where the first preset mileage value is 100 kilometers, the third preset mileage value is 10 kilometers. In other optional implementations, the third preset mileage value is determined according to the first preset mileage value based on a second preset ratio.

[0111] according to Figure 5 In one optional implementation shown, the electric vehicle charging / swapping reminder system further includes a navigation module 504. After the reminder module generates charging / swapping reminder information based on the number of alternative service stations, the navigation module obtains the user's confirmation of the charging / swapping instruction and generates navigation information from the electric vehicle to the target service station based on preset map data.

[0112] Generating navigation information from electric vehicles to the target service station can guide users to the target service station and improve efficiency.
