Description

Technical Field

[0001] The present invention belongs to the field of vehicle charging, and in particular, relates to a method and system for reminding an electric vehicle to charge. Background Art

[0002] At present, with the rapid development of new energy vehicles, market customers are increasingly demanding the range of electric vehicles. At present, the country is continuously supplementing public charging equipment, and various car companies are also taking measures to increase the range of electric vehicles.

[0003] Insufficient points of existing technology:

[0004] 1. Currently, electric vehicles, like fuel vehicles, have a range reminder. When the range is reduced to a certain threshold, the instrument will display a red reminder of the low range. However, due to the small number of charging stations and the inconvenience of electric vehicle charging compared to the refueling mode of fuel vehicles, the reminder function of this solution cannot effectively solve the user's range problem.

[0005] 2. When the range of an electric vehicle is reduced to the set range reminder threshold, if there is no charging equipment within this range, the current instrument display range reminder strategy cannot completely solve the habit of electric vehicle customers to worry about the range.

[0006] 3. After the user goes out, according to the current general range strategy, if the user is required to constantly calculate the range and the mileage that can be reached by the nearest charging device, this method will increase the user's concerns about the range of electric vehicles.

[0007] 4. Other travel charging reminder schemes have not taken into account users’ concerns about the time cost of charging. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figure 1 This is a flow chart of an electric vehicle charging reminder method according to an embodiment of the present invention. DETAILED DESCRIPTION

[0028] The following is a further detailed description of the specific implementation of the present invention by describing the embodiments with reference to the accompanying drawings, with the purpose of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate its implementation. In order to make the technical solution of the present invention clearer, the present invention is explained by the following embodiments.

[0029] With the popularity of new energy vehicles, the problem of vehicle charging and endurance needs to be solved urgently. In the existing charging solutions, fixed charging equipment such as charging piles and battery swap stations are generally used, but the popularity of these devices is not high, and they often require waiting in line, which wastes time. In order to overcome the above problems and further alleviate users' concerns about the range, such as Figure 1 As shown, the present application proposes a method for reminding an electric vehicle to charge, the method comprising:

[0030] Step S1, obtain the current cruising range of the vehicle and upload it to the vehicle computer (the vehicle computer refers to the in-vehicle infotainment product installed in the car, which can realize information communication between people and the car, the car and the outside world, and various components in the car). In this embodiment, the current cruising range of the vehicle is 280km.

[0031] Step S2: The user presets the maximum tolerance threshold of the cruising range in advance and uploads it to the vehicle computer. When the vehicle's cruising range is greater than the maximum tolerance threshold, the user will not feel worried. The setting of the value is completely in accordance with the user's autonomous will, and the user can flexibly set it according to his or her own preferences. In this embodiment, the maximum tolerance threshold is set to 40km.

[0032] Step S3: The user turns on the navigation, sets the destination, selects the navigation route and uploads it to the Internet server. At the same time, the navigation route distance is obtained and sent to the vehicle computer. In the existing vehicle navigation, after the user enters the destination, the navigation can automatically generate the corresponding navigation route and calculate the route distance. Furthermore, the existing navigation also supports automatically matching the best route according to different user needs (such as the shortest path, the shortest time, etc.) or providing all routes for users to choose independently.

[0033] Step S4, the vehicle computer calculates the difference between the vehicle's current cruising range and the maximum tolerance threshold, and compares the difference with the navigation route distance. In this embodiment, the difference between the vehicle's current cruising range and the maximum tolerance threshold is 240km (280-40=240km). When the navigation route distance is greater than 240km, it will trigger the user's sense of worry, and the user needs to be reminded to charge to avoid the feeling of worry; when the navigation route distance is less than or equal to 240km, it will not trigger the user's sense of worry, and the user can drive with peace of mind without worrying about the cruising range.

[0034] Step S5, based on the navigation route, the Internet server obtains the information of fixed charging equipment within the preset range of the navigation route and sends it to the vehicle computer. The Internet server combines big data technology to support wireless communication with the vehicle computer, fixed charging equipment, mobile charging vehicles, etc. Among them, based on the navigation route uploaded by the vehicle navigation, the Internet server can obtain the information of fixed charging equipment within the preset range of the navigation route through big data technology, including the presence or absence of fixed charging equipment, the location coordinates of fixed charging equipment, etc. In this embodiment, the preset range of the navigation route can be 5km. Taking a detour to charge within the range of 5km is within the acceptable range for users. Similarly, the preset range fully respects the user's wishes and provides convenience for users.

[0035] Step S6: The vehicle computer combines the comparison result of step S4 and the fixed charging device information to determine whether to remind the user to perform mobile charging.

[0036] Specifically, when the difference between the vehicle's current cruising range and the maximum tolerance threshold is greater than or equal to the navigation route distance, that is, when it will not trigger the user's sense of concern, the user will not be reminded to charge.

[0037] When the difference between the vehicle's current cruising range and the maximum tolerance threshold is less than the navigation route distance, and there is no fixed charging equipment within the preset interval of the navigation route, the user is reminded to charge.

[0038] When the difference between the vehicle's current cruising range and the maximum tolerance threshold is less than the navigation route distance, and there is a fixed charging device within the preset range of the navigation route, the vehicle computer actively asks the user whether he has time cost requirements. If the user has time cost requirements, the user will be reminded of mobile charging.

[0039] In this embodiment, mobile charging reminders can be made through the vehicle computer or a mobile terminal (such as a mobile phone, tablet, etc.) that is communicatively connected to the vehicle computer (WiFi, Bluetooth and other communication technologies may be used). The mobile charging reminder includes reminding the user whether to make a reservation for a mobile charging vehicle. After the user makes a reservation for a mobile charging vehicle, the vehicle computer sends the location and estimated arrival time on the navigation route selected by the user to the mobile charging vehicle via the Internet, and the mobile charging vehicle arrives at the location selected by the user in advance to wait. Obviously, the use of mobile charging vehicles is more flexible and on-call than traditional fixed charging equipment. They can wait at the user's designated location in advance without waiting in line, saving time costs. Regardless of whether there is a fixed charging device within the navigation route range, the charging service of the mobile charging vehicle is better.

[0040] At the same time, the real-time location coordinates of the mobile charging vehicle can be synchronized to the vehicle computer or the mobile terminal connected to the vehicle computer through the Internet server, so that the user can monitor the status of the mobile charging vehicle.

[0041] This embodiment also constructs an electric vehicle charging reminder system based on the above-mentioned electric vehicle charging reminder method, and the system includes a vehicle instrument, a vehicle computer, a vehicle navigation, a vehicle networking device, an Internet server, a fixed charging device, a mobile charging vehicle, and a mobile terminal, wherein the vehicle instrument, the vehicle navigation, and the mobile terminal are respectively connected to the vehicle computer; the vehicle computer is wirelessly connected to the Internet server through the vehicle networking device; the fixed charging device and the mobile charging vehicle are respectively wirelessly connected to the Internet server.

[0042] The vehicle instrument is used to send the vehicle's current cruising range to the vehicle computer; the on-board navigation is used to synchronize the vehicle's navigation route information to the vehicle computer; the vehicle network equipment can use WiFi equipment, SIM cards, etc. to achieve wireless communication connection between the vehicle computer and the Internet server, so as to send the vehicle computer's navigation data, etc. to the Internet server, and receive information about fixed charging equipment and mobile charging vehicles synchronized by the Internet server; the vehicle computer is used to preset system parameters (such as the maximum tolerance threshold, etc.), calculate the difference between the vehicle's current cruising range and the maximum tolerance threshold and compare the difference with the navigation route distance, and make mobile charging reminder judgments based on the confidence of the fixed charging equipment; the Internet server combines big data technology for data storage, forwarding and analysis; the fixed charging equipment and mobile charging vehicles are respectively used to synchronize their own status information to the Internet server; the mobile terminal is used for mobile charging reminders.

[0043] In this embodiment, the vehicle computer includes a human-computer interaction display screen and a vehicle computer controller, wherein the vehicle computer controller is respectively connected to the vehicle instrument, vehicle navigation, mobile terminal, vehicle networking equipment, and human-computer interaction display screen. The human-computer interaction display screen can be touch-sensitive, and mobile charging reminders can be realized through human-computer interaction; the vehicle computer controller is used for data analysis and processing.

[0044] This application uses the maximum tolerance threshold of the cruising range set by the user to participate in the cruising range charging reminder, which allows users to accept the maximum concern they set with peace of mind, and at the same time can meet the real-time demand for mobile charging services, allowing users to be more proactive and easy to control the way they remind their car to charge. At the same time, this application can also expand the appointment market service function between individual customers and mobile charging vehicles, promoting market development and economic development.

[0045] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
