BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Figure 1 This is a flowchart of the first embodiment of the charging reminder method of this application;

[0036] Figure 2 This is a schematic diagram of the hardware structure of the charging reminder device involved in the embodiment of the present application. DETAILED DESCRIPTION

[0037] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] Regarding the relevant technology, the charging reminder for electric vehicles can only remind the location of the charging station, but cannot add the charging piles in the daily community, the charging piles in the unit or other private charging locations into the charging reminder strategy, and thus cannot accurately provide reminders according to the needs of the car owner.

[0039] In the first aspect, the present application provides a charging reminder method for an electric vehicle, such as Figure 1 As shown, the charging reminder method includes:

[0040] Step S1: collecting and preprocessing vehicle travel data in real time, wherein the vehicle travel data includes travel power consumption information and current rechargeable position information of the vehicle.

[0041] Specifically, the above step S1 includes:

[0042] Step S1a: Collect the departure address information and destination address information of the vehicle, and confirm and update the home address and work address based on the departure address information and destination address information.

[0043] It should be noted that this application is intended to provide personalized charging reminders for the current vehicle. Since electric vehicles generally have shorter driving ranges, the most common daily driving routes are commuting to and from get off work. Therefore, in the embodiments of this application, by confirming the home address and work address, accurate power consumption trend prediction can be made for the route between the home address and the work address in subsequent steps.

[0044] Step S1b: Classify the vehicle's travel data into weekday travel data and weekend travel data according to the data collection date.

[0045] It's worth noting that during regular weekday driving, most trips involve repeated stops, such as work and school. The round-trip distance between home and destination generally doesn't exceed the electric vehicle's range, and a common charging location might be one of home or destination, or somewhere in between. Weekend use, however, encompasses weekends and holidays, and the vehicle's current travel locations are more diverse. To ensure that weekend data doesn't interfere with daily data, the two types of data should be separated.

[0046] Step S2: Establish a charging location information database based on the current charging location information of the vehicle.

[0047] It should be noted that electric vehicles can be charged at public charging stations. However, as urban infrastructure improves, some shopping malls and residential parking lots are equipped with charging piles. However, these charging piles are both public and private. The charging location information database established by this application for the current vehicle only includes locations where the current vehicle can charge, avoiding the situation where the vehicle arrives at the charging location but cannot charge.

[0048] Specifically, step S2 includes: confirming whether each parking space of the current vehicle in the travel data can be charged. If it is confirmed that the current vehicle can be charged at the parking space, the parking space is recorded in the charging space information database.

[0049] Furthermore, it is confirmed whether the parking location is a public charging location or a private charging location, or whether it is a public or employee charging location, and the usage information of the charging location is input into the charging location information database.

[0050] Preferably, the charging location information database can be linked to a city map system to obtain public charging parking spaces.

[0051] It is worth noting that by confirming the above parking space information, the charging location information database includes not only public charging stations but also charging locations such as the current vehicle's private charging piles or dedicated parking piles that will not be recorded in the city map network. Based on these locations, accurate parking space recommendations and charging reminders can be provided for the current vehicle.

[0052] Step S3: updating the trip power consumption trend according to the power consumption information of each trip, and calculating the estimated power consumption result of the next vehicle trip based on the updated trip power consumption trend.

[0053] The above step S3 specifically includes:

[0054] Step S3a: updating the vehicle's travel power consumption trend on weekdays based on the travel power consumption information of the weekday travel data.

[0055] In some specific implementations, after initialization, the system identifies the home location and proactively confirms with the vehicle owner to locate the home address. It also confirms whether the parking space can be used for charging and whether it is a public or private charging space, and includes it in the charging location information database. When the vehicle owner goes to a company, office building, enterprise or institution for the first time on a weekday, it proactively confirms with the vehicle owner to locate the work address and confirm whether the parking space can be used for charging and whether it is a public or employee charging space. Once the location is determined, the driving power consumption of the entire journey, the temperature inside and outside the vehicle, and the power consumption of the vehicle owner's entertainment system, air-conditioning system, etc. throughout the journey are all included in the data accumulation of power consumption habits.

[0056] Furthermore, the initial trip locates basic information such as the location. Subsequent trips continuously eliminate data with large differences in power consumption for driving, entertainment, etc. and take the average data. The changing trend of air-conditioning power consumption is recorded according to the changes in temperature conditions, and the next power consumption is estimated based on the changing trend. The data is corrected and optimized based on the actual power consumption next time. Through such personalized data correction, the owner's accurate power consumption information is obtained. As an information database that can be connected to the Internet, the charging location information database shares the public charging location information of other owners, protects the information of private charging positions that are not open to the public, and realizes personalized charging reminders for daily use.

[0057] Step S3b: updating the weekend travel power consumption trend of the vehicle according to the travel power consumption information of the weekend travel data.

[0058] It is worth noting that weekend usage includes holidays and the locations are more diverse. First of all, the system will ensure that the data used on weekends will not interfere with the data used on daily basis. Therefore, even if the place arrived at on the weekend is the work address, this data will not be used as correction data for daily use, but will be processed as data of a certain usage on the weekend.

[0059] In some specific implementation methods, the travel and entertainment usage data of weekends are processed according to the time average. Because the usage time on weekends varies, all data will be increased by the time average. According to the navigation, several places such as shopping malls and cinemas are locked, and confirmation is added on whether the parking space can be charged and whether it is a public charging space (some shopping malls have brand restrictions on charging in parking spaces), and the charging location information is included. After multiple data optimizations, charging reminders can be given in advance before weekend travel or before the end of daily work at the end of the weekend.

[0060] Step S3c: collecting the air conditioning power consumption data of the vehicle's travel data, and correcting the air conditioning power consumption trend according to the air conditioning power consumption data.

[0061] Specifically, the current vehicle air conditioning power consumption data is divided into winter air conditioning power consumption data and summer air conditioning power consumption data according to the current vehicle air conditioning operating mode. The winter or summer air conditioning power consumption data is selected to correct the vehicle's power consumption trend during weekdays or weekends.

[0062] It is worth mentioning that air conditioning is the main power-consuming system. Frequent use in summer will significantly increase the frequency of vehicle charging. The power consumption of air conditioning is related to temperature, air volume, etc. When the vehicle is started, it needs to be adjusted to a comfortable temperature as soon as possible, and the power consumption will increase suddenly. When maintaining the temperature, the power consumption will decrease. If it is maintained stable, the power consumption will increase relatively if it is used for too long. For daily use, it is sufficient to increase the power consumption forecast of the air conditioner and make a reminder. However, on weekends, it is necessary to predict whether charging is needed in advance based on the destination and remind the owner.

[0063] Furthermore, winter is positioned in the system as air conditioning use in heating mode, and data in heating mode is included in winter usage data and associated with daily and weekend data, supporting daily and weekend data correction.

[0064] The air conditioning heating of electric vehicles is different from that of fuel vehicles. The air conditioning heating of fuel vehicles can mainly rely on engine heat and consumes little electricity. However, the power consumption of air conditioning heating of electric vehicles will significantly increase the frequency of vehicle charging. The power consumption of air conditioning is related to temperature, air volume, etc. When the vehicle is started, it needs to be adjusted to a comfortable temperature as soon as possible, and the power consumption will increase suddenly. When maintaining the temperature, the power consumption will decrease. If it is maintained stable, in heating mode, the power consumption will be relatively reduced over time. For daily use, it is sufficient to increase the power consumption forecast of the air conditioner and make a reminder. However, on weekends, it is necessary to predict whether charging is needed in advance based on the destination and remind the owner.

[0065] Step S4: selecting a recommended charging location from the charging location information database based on the power consumption estimation result of the next vehicle trip, and planning a recommended charging time and charging route based on the recommended charging location.

[0066] Furthermore, in the process of planning the recommended charging time and charging route, the recommended charging location and charging time can be selected from the charging location optional information library based on the owner's route and safety considerations.

[0067] In some preferred implementations, weather forecast information is collected and charging reminders are issued based on the consumption of rain or snow. When the weather forecast information shows that the consumption of rain or snow is high, a reminder to charge in advance is issued to the vehicle.

[0068] It is worth noting that if rainy or snowy weather occurs during the above-mentioned usage, and functions such as wipers, defrost and defogger are used, the data will be recorded separately and will not affect the correction of the main data. It will be included in the power consumption in rainy and snowy conditions together with the temperature information, and associated with daily and weekend data to support daily and weekend data correction. At the same time, combined with weather forecast information, it will give a reminder to charge in advance when rainy and snowy consumption is high. At the same time, if there is a forecast of heavy rain or other weather, it is recommended not to use the vehicle, and a relatively safe parking location will be recommended.

[0069] It is worth noting that, because the charging location information database in the embodiment of the reminder method of this application is maintained based on navigation charging stations and owner usage information, it is more comprehensive than general navigation information. Unlike fuel vehicles, electric vehicles have many charging options, including charging stations, brand-name direct battery replacement charging services, charging piles in residential parking spaces, and rechargeable parking spaces in public places. Navigation cannot make a good judgment on these, so collecting and collecting user feedback is a good way to accumulate data. The collection and organization of rechargeable locations is very important for optimizing charging reminder methods.

[0070] It should be noted that the charging reminder method for the electric vehicle of the present application is not limited to the step sequence in the above embodiment, and the above step sequence can be reasonably replaced and adjusted according to actual working conditions.

[0074] A prediction module, which is used to update the trip power consumption trend based on the power consumption information of each trip, and calculate the estimated power consumption result of the next vehicle trip based on the updated trip power consumption trend;

[0075] The reminder module is used to select a recommended charging location in the charging location information library based on the power consumption estimation result of the next vehicle trip, and plan the recommended charging time and charging route based on the recommended charging location.

[0076] Specifically, the data collection module is used to collect the departure address information and destination address information of the vehicle, and confirm and update the home address and work address based on the departure address information and destination address information.

[0077] Furthermore, the data collection module is further configured to classify the vehicle's travel data into weekday travel data and weekend travel data according to the data collection date.
