Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a charging method and a vehicle. Background Technology

[0002] New energy vehicles, with their advantages of zero or low emissions and high energy efficiency, have become the direction for the transformation of the automotive industry. As a key support for the development of new energy vehicles, vehicle charging technology is becoming increasingly important in its research and application. Among these, reducing charging costs and improving the intelligence level of charging have become key focuses for researchers. Summary of the Invention

[0003] In view of the above problems, this application provides a charging method and a vehicle, which can improve the intelligence level of vehicle charging.

[0004] In a first aspect, a charging method is provided, the method comprising: Get vehicle usage plan information and electricity price discount information for a specified time period; The first charging plan information for the specified time period is determined based on the vehicle usage plan information and the electricity price discount time information; Once it is confirmed that the vehicle and the charging equipment are successfully connected, a second charging plan is generated based on the current time and the first charging plan information for this charging. The vehicle is charged according to the second charging plan information.

[0005] In this embodiment, by acquiring vehicle usage plan information and electricity price discount time information within a specified time period; determining first charging plan information within the specified time period based on the vehicle usage plan information and the electricity price discount time information; and generating second charging plan information for this charging based on the current time and the first charging plan information when it is determined that the vehicle and charging equipment are successfully connected; and then controlling the vehicle charging based on the second charging plan information, it is possible to combine the user's vehicle usage plan and automatically make full use of peak and off-peak electricity prices according to the electricity price discount time, thereby not only effectively improving the intelligence level of vehicle charging, but also improving the utilization efficiency of power resources, reducing vehicle charging costs, and improving the charging experience for vehicle users.

[0006] In conjunction with the above methods, in some possible implementations, the vehicle usage plan information includes temporary vehicle usage plan information and / or periodic vehicle usage plan information. The temporary vehicle usage plan information includes the first departure time for a single vehicle use, and the periodic vehicle usage plan information includes the second departure time for each vehicle use within the specified time period. Determining the first charging plan information based on the vehicle usage plan information and the electricity price discount time information includes: If it is determined that the vehicle use plan information includes temporary vehicle use plan information and periodic vehicle use plan information, the interval between the first departure time and the second departure time is determined; If the interval duration is determined to be greater than a preset interval duration threshold, the first preferential charging period corresponding to the first departure time and the second preferential charging period corresponding to the second departure time are determined according to the electricity price preferential time information. The first discounted charging period corresponding to the first departure time and the second discounted charging period corresponding to the second departure time are used as the first charging plan information.

[0007] In conjunction with the above method, in some possible implementations, the electricity price discount time information includes at least one electricity price discount period. The step of determining the first discounted charging period corresponding to the first departure time and the second discounted charging period corresponding to the second departure time based on the electricity price discount time information includes: Determine a first time period with a first duration prior to the first departure time and a second time period with a second duration prior to the second departure time; The interval within the first time period that belongs to the electricity price discount period shall be defined as the first discounted charging period; The interval within the second time period that belongs to the electricity price discount period shall be designated as the second preferential charging period.

[0008] In some possible implementations, combining the above methods, determining the first charging plan information based on the vehicle usage plan information and the electricity price discount time information further includes: If the interval between the first departure time and the second departure time of the Nth vehicle use in the periodic vehicle use plan information is less than or equal to a preset interval threshold, the second departure time of the Nth vehicle use will be deleted to obtain updated vehicle use plan information. The first charging plan information is determined based on the updated vehicle usage plan information and the electricity price discount time information.

[0009] In this embodiment, the first charging plan information within the specified time period can be determined based on the departure time in the combination of the user's temporary vehicle use plan information and periodic vehicle use plan information, combined with the preferential charging time period in the electricity price preferential time information. This can provide reliable data basis for automatically making full use of peak and off-peak electricity prices.

[0010] In conjunction with the above methods, in some possible implementations, the first charging plan information includes the departure time of each vehicle usage plan within the specified time period, and the preferential charging period corresponding to the vehicle usage plan; the step of generating second charging plan information based on the current time and the first charging plan information after confirming that the vehicle and charging equipment are successfully connected includes: If the vehicle and the charging equipment are successfully connected, the target discounted charging period corresponding to the vehicle use plan whose departure time is closest to the current time is determined from the first charging plan information; If it is determined that the current time belongs to the target preferential charging period, the target duration between the current time and the end time of the target preferential charging period is determined, and the current remaining battery power and preset charging power of the vehicle are obtained. Based on the target duration, the current remaining battery power and the preset charging power, the second charging plan information is generated.

[0011] In conjunction with the above method, in some possible implementations, the second charging plan information includes the target charging start time and the target charging end time for this charging session; the step of generating the second charging plan information based on the target duration, the current remaining battery power, and the preset charging power includes: The target charging time threshold is determined based on the current remaining battery power and the preset charging power. If the target duration is determined to be greater than or equal to the target charging duration threshold, the current time is taken as the target charging start time for this charging, and the target charging end time is determined according to the target charging duration threshold to obtain the second charging plan information.

[0012] In some possible implementations, in conjunction with the above methods, the generation of the second charging plan information based on the current remaining battery power and the preset charging power further includes: If the target duration is determined to be less than the target charging duration threshold, a vehicle usage details input prompt box is displayed, and the target remaining battery level at the end of the target preferential charging period is determined based on the target duration, the current remaining battery level, and the preset charging power. The vehicle usage details input prompt box is used to prompt the user to input the departure address and destination address of the most recent vehicle usage plan. The required electricity consumption is determined based on the departure address and the destination address. The second charging plan information is determined based on the amount of electricity to be used and the target remaining amount of electricity.

[0013] In some possible implementations, combining the above methods, determining the second charging plan information based on the required power consumption and the target remaining power consumption includes: If the target remaining power is determined to be greater than or equal to the power to be used, the current time is taken as the target charging start time for this charging, and the end time of the target preferential charging period is taken as the target charging end time for this charging, so as to obtain the second charging plan information.

[0014] In some possible implementations, in conjunction with the above method, determining the second charging plan information based on the required power consumption and the target remaining power consumption further includes: If it is determined that the target remaining power is less than the power to be used, the difference between the power to be used and the target remaining power is determined. The non-preferential charging duration is determined based on the difference and the preset charging power. The current time is used as the target start time for this charging, and the target end time for this charging is determined based on the target duration and the non-preferential charging duration, so as to obtain the second charging plan information.

[0015] In this embodiment, when the vehicle and charging equipment are successfully connected, a second charging plan is generated based on the current time and the first charging plan information. The vehicle is then charged according to the second charging plan information. This allows for the automatic utilization of peak and off-peak electricity prices during the charging process, thereby not only improving the intelligence of vehicle charging but also increasing the efficiency of power resource utilization, reducing vehicle charging costs, and enhancing the charging experience for vehicle users.

[0016] In conjunction with the above methods, in some possible implementations, the electricity price discount time information includes a first electricity price corresponding to each electricity price discount period, and a second electricity price for other periods besides the electricity price discount period. The second charging plan information includes the target charging start time and the target charging end time for this charging session. The method further includes: When it is determined that the charging has ended, the first electricity cost during the electricity price discount period, the second electricity cost during the non-electricity price discount period, and the electricity cost saved during this charging are determined based on the target charging start time, the target charging end time, the first electricity price, and the second electricity price. The first electricity cost, the second electricity cost, and the electricity savings are displayed through a preset interface.

[0017] In this embodiment, the first electricity cost during the electricity price discount period, the second electricity cost during the non-electricity price discount period, and the electricity cost saved during this charging process can be effectively generated and displayed. This helps vehicle users obtain charging cost information in a timely and efficient manner, thereby effectively improving the charging experience of vehicle users.

[0018] Secondly, a charging device is provided, the device comprising: The acquisition module is used to obtain vehicle usage plan information and electricity price discount time information within a specified time period; The first determining module is used to determine the first charging plan information within the specified time period based on the vehicle usage plan information and the electricity price discount time information; The second determining module is used to generate a second charging plan information for this charging based on the current time and the first charging plan information when it is determined that the vehicle and the charging equipment are successfully connected. The control module is used to control the charging of the vehicle according to the second charging plan information.

[0019] Thirdly, a vehicle is provided, the vehicle comprising: Memory, used to store executable program code; A processor is configured to call and run the executable program code from the memory, causing the vehicle to perform the method described in the first aspect above.

Detailed Implementation

[0023] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0024] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0025] To improve the utilization rate of electricity resources, power grids typically implement peak-valley pricing. This involves dividing the 24 hours of the day into peak and off-peak periods based on grid load changes and setting differentiated prices. This price mechanism incentivizes users to adjust their electricity consumption times, achieving "peak shaving and valley filling," thereby improving the efficiency of electricity resource utilization. Currently, vehicles cannot automatically take full advantage of peak-valley pricing during charging, which undoubtedly hinders the efficient use of electricity resources and reduces vehicle operating costs.

[0026] To address the issue of vehicles failing to automatically utilize peak-valley electricity pricing during charging, this application provides a charging method and a vehicle. This charging method acquires vehicle usage plan information and electricity price discount time information for a specified time period; determines a first charging plan for the specified time period based on the vehicle usage plan information and the electricity price discount time information; and, upon confirming a successful connection between the vehicle and the charging equipment, generates a second charging plan for the current charging session based on the current time and the first charging plan information; and then controls the vehicle charging according to the second charging plan information. This method enables automatic utilization of peak-valley electricity pricing during vehicle charging, effectively improving the intelligence of vehicle charging, increasing the efficiency of electricity resource utilization, reducing vehicle charging costs, and enhancing the charging experience for vehicle users.

[0027] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0028] See Figure 1 , Figure 1 This is a flowchart illustrating the steps of a charging method provided in one embodiment of this application. The charging method can be executed by a controller in the vehicle, such as a PDCU (Power Domain Controller), VCU (Vehicle Controller), or a controller in a BMS (Battery Management System). The method may include the following steps: Step 101: Obtain vehicle usage plan information and electricity price discount information for the specified time period.

[0029] The specified time period can be the next 48 hours, the next 72 hours, the next week, the next two weeks, etc. This vehicle usage plan information includes temporary vehicle usage plan information and / or periodic vehicle usage plan information. Temporary vehicle usage plan information can be understood as vehicle arrangement information formulated by the user for unplanned, sudden, or temporary vehicle usage needs. It is usually not long-term or regular and can be flexibly adjusted according to actual needs. Periodic vehicle usage plan information can be understood as vehicle arrangement information formulated by the user for regular, periodic, or recurring vehicle usage needs.

[0030] In some embodiments, users can obtain the vehicle usage plan information and the electricity price discount time information through the HUT (Human-Machine Interaction Unit) in the vehicle, or through the APP (application) in the vehicle terminal.

[0031] In other embodiments, the electricity price discount time information can be obtained from the cloud. For example, the cloud server can obtain the current location of the vehicle, obtain the time-of-use electricity price information of the area where the current location is located based on the vehicle's current location, and send the time-of-use electricity price information to the vehicle.

[0032] Step 102: Determine the first charging plan information within the specified time period based on the vehicle usage plan information and the electricity price discount time information.

[0033] The temporary vehicle use plan information may include the first departure time of a single vehicle use, and the periodic vehicle use plan information may include the second departure time of each vehicle use within the specified time period.

[0034] In one implementation, step 102 can be carried out as follows: Figure 2 ( Figure 2 Based on this application Figure 1 The flowchart illustrating a charging method in the illustrated embodiment includes: S11, if it is determined that the vehicle use plan information includes temporary vehicle use plan information and periodic vehicle use plan information, determine the interval between the first departure time and the second departure time.

[0035] For example, the periodic car use plan is to go to work at 8:00 every day, and the temporary car use plan is to attend a party at 12:00 noon on Tuesday. If the specified duration is one week, the first departure time is 12:00 noon on Tuesday. The second departure time for each car use plan in the periodic car use plan is 8:00. Determine the interval between the first departure time and 8:00 every day within the week. Taking the car use plan on Tuesday in the periodic car use plan as an example, the interval between the first departure time and the second departure time is 4 hours. Taking the car use plan on Wednesday in the periodic car use plan as an example, the interval between the first departure time and the second departure time is 20 hours.

[0036] S12, if it is determined that the interval duration is greater than the preset interval duration threshold, the first preferential charging period corresponding to the first departure time and the second preferential charging period corresponding to the second departure time are determined according to the electricity price preferential time information.

[0037] The electricity price discount time information includes at least one electricity price discount period. This step can determine a first time period before the first departure time, with a first time interval between the first departure time and the second departure time, with a second time interval between the second departure time and the second departure time; the interval within the first time period that belongs to the electricity price discount period is designated as the first discounted charging period; and the interval within the second time period that belongs to the electricity price discount period is designated as the second discounted charging period.

[0038] For example, the electricity price discount time information includes: 8 hours of discount time: 0:00-8:00, 6 hours of high-price time: 10:00-12:00 and 18:00-22:00, and 10 hours of normal electricity price period. If the first departure time is 12:00, the time period before 12:00 that is separated from 12:00 by a first time interval (e.g., 10 hours) (i.e., 2:00-12:00) can be used as the first time period, and 2:00-8:00 within this first time period is the first discounted charging period corresponding to the first departure time. If the second departure time is 9:00, the time period separated from 9:00 by a second time interval (e.g., 5 hours) (i.e., 4:00-9:00) can be used as the second time period, and 4:00-8:00 within this second time period is the second discounted charging period corresponding to the second departure time.

[0039] It should be noted that the preset interval time threshold can be the time required for the vehicle to gain 1%, 2%, 3%, or 5% of its battery capacity. If the interval between the first departure time and the second departure time is less than or equal to the preset interval time threshold, the vehicle charging time is too short to guarantee that the vehicle can gain the preset minimum battery capacity. The first and second times can be the time required for the vehicle to gain 75%, 80%, 82%, 85%, 94%, 97.5%, 99%, or 100% of its battery capacity. The first and second times can be the same or different, and the specific data above are only used to illustrate the first and second times and are not intended to limit a specific range.

[0040] S13, the first preferential charging period corresponding to the first departure time and the second preferential charging period corresponding to the second departure time are used as the first charging plan information.

[0041] The first charging plan information may include the first departure time of the temporary vehicle use plan, the second departure time of each vehicle use plan in the periodic vehicle use plan, the first preferential charging period corresponding to the first departure time, and the second preferential charging period corresponding to each second departure time.

[0042] The schemes shown in S11 to S13 enable the determination of the vehicle usage plan information, which includes both temporary and periodic vehicle usage plan information. If the interval between the second departure time of each vehicle usage in the periodic vehicle usage plan and the first departure time in the temporary vehicle usage plan is greater than a preset interval threshold, the first preferential charging period corresponding to the first departure time and the second preferential charging period corresponding to the second departure time are determined based on the electricity price discount time information. This yields the first charging plan information, which includes the first preferential charging period corresponding to the first departure time and the second preferential charging period corresponding to the second departure time. This effectively determines the preferential charging period corresponding to each planned vehicle usage and provides reliable data for automatically making full use of peak and off-peak electricity prices.

[0043] In another embodiment, the implementation process of step 102 can be as follows: Figure 3 ( Figure 3 Based on this application Figure 1 The flowchart illustrating another charging method in the illustrated embodiment includes: S21, if the interval between the first departure time and the second departure time of the Nth trip in the periodic car use plan information is less than or equal to a preset interval threshold, the second departure time of the Nth trip is deleted to obtain updated car use plan information.

[0044] Where N is an integer greater than zero.

[0045] It should be noted that deleting the second departure time of the Nth vehicle use can be understood as prioritizing the charging needs of the temporary vehicle use plan when generating the first charging plan information, if a conflict exists between a vehicle use plan in the periodic vehicle use plan and a temporary vehicle use plan. The conflict between a vehicle use plan in the periodic vehicle use plan and a temporary vehicle use plan can be understood as the interval between the departure time of the vehicle use plan in the periodic vehicle use plan and the departure time of the temporary vehicle use plan being less than or equal to a preset interval threshold. Since the vehicle charging time is too short when this interval is less than or equal to the preset interval threshold, it cannot guarantee that the vehicle will be charged to the preset minimum battery level; therefore, it can be understood that a conflict exists between a vehicle use plan in the periodic vehicle use plan and a temporary vehicle use plan.

[0046] In some embodiments, when prioritizing the charging needs of the temporary vehicle use plan, a priority adjustment request box can be displayed to the user. This priority adjustment request box may include a first button and a second button. In response to receiving a first adjustment request instruction triggered by the first button, the charging needs of the temporary vehicle use plan are prioritized. For example, this can be achieved by deleting the second departure time of the Nth vehicle use. In response to receiving a second adjustment instruction triggered by the second button, the charging needs of the temporary vehicle use plan are ignored. That is, when generating the first charging plan message, the temporary vehicle use plan information is not considered.

[0047] S22, determine the first charging plan information based on the updated vehicle usage plan information and the electricity price discount time information.

[0048] It should be noted that in the updated vehicle usage plan information, the interval between the departure time of each trip in the current period's vehicle usage plan (i.e., the second departure time) and the first departure time in the temporary vehicle usage plan information is greater than a preset interval threshold. The implementation process for determining the first charging plan information based on the updated vehicle usage plan information and the electricity price discount time information can be found in [reference needed]. Figure 2 The descriptions in S12 and S13 are not repeated here.

[0049] Through the schemes shown in S21 to S22, when it is determined that the vehicle usage plan information includes temporary vehicle usage plan information and periodic vehicle usage plan information, if the interval between the first departure time and the second departure time of the Nth vehicle usage in the periodic vehicle usage plan information is less than or equal to a preset interval threshold, the second departure time of the Nth vehicle usage is deleted to obtain updated vehicle usage plan information. The first charging plan information is determined based on the updated vehicle usage plan information and the electricity price discount time information. This not only effectively ensures that the vehicle's remaining battery power can meet the user's vehicle usage plan needs, but also effectively improves the intelligence level of automatically making full use of peak and off-peak electricity prices, which is conducive to improving the reliability of automatically making full use of peak and off-peak electricity prices.

[0050] In another embodiment, if the periodic vehicle use plan information includes multiple different periodic plans, it can be first determined whether there is a conflict between the departure times corresponding to the multiple different periodic plans. If a conflict is determined, the minimum battery level of the two conflicting vehicle use plans is determined, and the vehicle's remaining battery level is guaranteed to be greater than or equal to the minimum battery level before the target departure time of the two conflicting vehicle use plans. The target departure time is the departure time corresponding to the vehicle use plan with the earlier departure time among the two conflicting vehicle use plans.

[0051] It should be noted that, in cases where a conflict exists, the vehicle charging time is too short to guarantee that the vehicle will be able to reach the preset minimum charge level. Therefore, ensuring that the vehicle's remaining charge reaches the minimum charge level required for both driving plans before the departure time of the two conflicting plans can effectively prevent users from being delayed in using the vehicle due to untimely charging.

[0052] For example, taking a periodic car rental plan that includes periodic plan A and periodic plan B as an example, when determining whether there is a conflict between the departure times corresponding to multiple different periodic plans, the waiting interval length between each departure time in periodic plan A and each departure time in periodic plan B can be determined. If the waiting interval length is greater than or equal to the target interval length threshold, it is determined that there is no conflict between the departure times corresponding to periodic plan A and periodic plan B; if the waiting interval length is less than the target interval length threshold, it is determined that there is a conflict between the departure times corresponding to periodic plan A and periodic plan B.

[0053] Step 103: If it is confirmed that the vehicle and the charging equipment are successfully connected, generate a second charging plan for this charging based on the current time and the first charging plan information.

[0054] The implementation process of this step can be as follows: Figure 4 ( Figure 4 Based on this application Figure 1 The flowchart of another charging method shown in the embodiment illustrates the steps, including: S31, if it is determined that the vehicle and the charging equipment are successfully connected, determine from the first charging plan information the target preferential charging period corresponding to the car use plan whose departure time is closest to the current time after the current time.

[0055] S32, if it is determined that the current time belongs to the target preferential charging period, determine the target duration between the current time and the end time of the target preferential charging period, and obtain the vehicle's current remaining battery power and preset charging power.

[0056] Specifically, if it is determined that the current time does not belong to the target discounted charging period, the current time is updated, and it is determined again whether the current time belongs to the target discounted charging period.

[0057] S33, generate the second charging plan information based on the target duration, the current remaining battery power, and the preset charging power.

[0058] The second charging plan information includes the target charging start time and the target charging end time for this charging operation. In one embodiment, a target charging duration threshold can be determined based on the current remaining battery power and the preset charging power; if the target duration is determined to be greater than or equal to the target charging duration threshold, the current time is taken as the target charging start time for this charging, and the target charging end time is determined based on the target charging duration threshold to obtain the second charging plan information.

[0059] It should be noted that the implementation method for determining the target charging time threshold based on the current remaining battery power and the preset charging power can be as follows: obtain a preset maximum remaining battery power; determine the amount to be charged based on the maximum remaining battery power and the current remaining battery power; determine the target time required for the vehicle's remaining battery power to increase by the amount to be charged under the preset charging power; and use this target time as the target charging time threshold. The system can pre-store the increase in the vehicle's remaining battery power per unit time under different charging power. Therefore, when determining the target time required for the vehicle's remaining battery power to increase by the amount to be charged under the preset charging power, the amount to be charged can be divided by the increase in the vehicle's remaining battery power per unit time corresponding to the preset charging power to obtain the target time.

[0060] In another implementation, if the target duration is determined to be less than the target charging duration threshold, a vehicle usage details input prompt box is displayed, and the target remaining battery level at the end of the target discounted charging period is determined based on the target duration, the current remaining battery level, and the preset charging power. The vehicle usage details input prompt box prompts the user to input the departure and destination addresses of the most recent vehicle usage plan. The remaining battery level is determined based on the departure and destination addresses. The second charging plan information is determined based on the remaining battery level and the target remaining battery level.

[0061] The implementation process for determining the second charging plan information based on the required power consumption and the target remaining power consumption in this embodiment may include the following two methods: Method 1: If the target remaining power is greater than or equal to the power to be used, the current time is taken as the target charging start time and the end time of the target preferential charging period is taken as the target charging end time to obtain the second charging plan information.

[0062] Method 2: If the target remaining power is less than the available power, determine the difference between the available power and the target remaining power; determine the non-discounted charging duration based on the difference and the preset charging power; use the current time as the target charging start time for this charging, and determine the target charging end time for this charging based on the target duration and the non-discounted charging duration to obtain the second charging plan information.

[0063] Specifically, when determining the target charging end time for this charging session based on the target duration and the non-discounted charging duration, the charging duration for this session can be determined based on the target duration and the non-discounted charging duration; the target charging end time can be determined based on the current time and the charging duration for this session.

[0064] The above technical solution can effectively generate a second charging plan based on the current time and the first charging plan information when the vehicle and charging equipment are successfully connected. The vehicle charging is controlled according to the second charging plan information, which can automatically make full use of peak and off-peak electricity prices. This not only effectively improves the intelligence of vehicle charging, but also improves the utilization efficiency of power resources, reduces vehicle charging costs, and enhances the charging experience for vehicle users.

[0065] Step 104: Control the vehicle to charge according to the second charging plan information.

[0066] The above technical solution can determine the first charging plan information within a specified time period by combining the user's vehicle usage plan information and electricity price discount time information. That is, a long-term charging plan (i.e., the first charging plan information) is first formulated based on the electricity price discount time and vehicle usage plan. Then, after the vehicle and the charging equipment are successfully connected, the first charging plan information is adjusted according to the current time to obtain the charging plan for this charging (i.e., the second charging plan information), and the vehicle charging is controlled according to the second charging plan. It can automatically make full use of peak and off-peak electricity prices by combining the user's vehicle usage plan information, thereby not only effectively improving the intelligence of vehicle charging, but also improving the utilization efficiency of power resources, reducing vehicle charging costs, and improving the charging experience for vehicle users.

[0067] Optionally, the electricity price discount time information may further include a first electricity price corresponding to each electricity price discount period, and a second electricity price for other periods besides the electricity price discount period. The second charging plan information includes the target charging start time and target charging end time for this charging. The charging method may further include... Figure 5 ( Figure 5 Based on this application Figure 1 The flowchart illustrating another charging method in the illustrated embodiment shows the following steps: Step 105: If the charging is determined to be finished, determine the first electricity cost during the electricity price discount period, the second electricity cost during the non-electricity price discount period, and the electricity cost saved during this charging based on the target charging start time, the target charging end time, the first electricity price, and the second electricity price. Step 106: Display the first electricity cost, the second electricity cost, and the electricity savings through a preset interface.

[0068] Through steps 105 to 106 above, the first electricity cost during the electricity price discount period, the second electricity cost during the non-electricity price discount period, and the electricity cost saved during this charging process can be effectively generated and displayed. This helps vehicle users obtain charging cost information in a timely and efficient manner, thereby effectively improving the charging experience for vehicle users.

[0069] Compared to existing technologies such as CN106965699B, the above technical solution effectively combines user vehicle usage plan information and electricity price discount time information to determine the first charging plan information within a specified time period. Specifically, it first formulates a long-term charging plan (i.e., the first charging plan information) based on the electricity price discount time and vehicle usage plan. Then, after the vehicle successfully establishes a connection with the charging equipment, it adjusts the first charging plan information according to the current time to obtain the charging plan for this charging session (i.e., the second charging plan information), and controls vehicle charging based on the second charging plan information. Furthermore, this application includes finer-grained information processing of vehicle usage plan information. This not only solves the problem of how to charge the vehicle according to the electricity price discount time and vehicle usage plan, but also how to avoid conflicts between multiple usage plans and how to more efficiently display charging fee discount information to maximize user experience. This not only effectively ensures that the vehicle's remaining battery power meets the user's usage plan needs by combining user usage plan information, but also effectively improves the intelligence level of automatically making full use of peak and off-peak electricity prices based on the electricity price discount time, which is conducive to improving the reliability of automatically making full use of peak and off-peak electricity prices. Furthermore, it can improve the user experience of the charging fee payment process, thereby enhancing the vehicle user experience.

[0070] Figure 6 This is a block diagram of a charging system provided in an exemplary embodiment of this application, such as... Figure 6 As shown in this application, the Figures 1 to 5 The charging method shown can be based on Figure 6 The system architecture implementation in this charging method involves a user layer that handles human-machine interaction. This user layer may include a vehicle-side HUT and / or a mobile app. Electricity price discount information can be obtained through a cloud layer, which includes a smart charging cloud server and a TSP cloud platform. This cloud layer sends the electricity price discount information to the vehicle's PDCU via a TBOX. The PDCU generates the first charging plan information and the second charging plan information, and sends the second charging plan information to the battery management system. The battery management system then controls the vehicle charging based on the second charging plan information.

[0071] Figure 7 It is based on Figure 6 The charging system shown provides a timing diagram of a charging system, such as... Figure 7 As shown, the charging process can include four stages: complex usage plan settings, electricity price data and intelligent decision-making, intelligent charging execution, and detailed report generation. In the complex usage plan settings stage, users set the charging mode for their usage plan via the app, sequentially activating a single usage plan (e.g., Friday 18:00), repeating plan 1 (e.g., Monday, Wednesday, and Friday 08:00), and repeating plan 2 (e.g., Tuesday and Thursday 19:30), setting the SOC limit to 90%. The app then sends the complete usage plan settings to the TSP (Telematics Service Provider), which forwards the settings instructions and transmits the complete plan to the TBOX (Telematics Box) via CAN signal. Finally, the plan is simultaneously displayed on the HUT, and the user confirms the usage plan. In the electricity price data and intelligent decision-making stage, the cloud can push preferential electricity price ranges (e.g., 22:00-06:00) to the TSP, which generates electricity price data. The TBOX then forwards the electricity price information to the PDCU. The PDCU intelligently analyzes all usage plans and calculates the optimal charging time, generating a second charging plan. During the intelligent charging execution phase, the PDCU executes intelligent charging strategies based on the calculation results (second charging plan information), such as starting charging at 22:00 on Wednesday night to prepare for use on Thursday and Friday. It also dynamically adjusts the charging strategy according to the usage time of each plan. During charging, real-time charging status is reported to the TSP and charging data is synchronized to the app. In the detailed report generation phase, if charging is confirmed to be complete, the PDCU reports a detailed report to the TSP, which then forwards the charging report to the app. This detailed report may include the first electricity cost during the discounted electricity period, the second electricity cost during the non-discounted electricity period, and the electricity savings for this charging. Optionally, the app can calculate the savings for each plan, generate a personalized report, and push a detailed charging report, ultimately displaying the amount saved by the user (e.g., saving XX yuan across 3 usage plans).

[0072] Figure 8 This is a flowchart of a charging method provided by another exemplary embodiment of this application, such as... Figure 8As shown, after initiating the charging process, users can first set charging parameters, and then enter the charging mode selection stage. The charging modes include three options: scheduled charging, immediate charging, and custom charging. If immediate charging is selected, the system will directly start charging, and the process will end after charging is complete. If custom charging is selected, the system will complete charging within the specified time period and end the process. When the scheduled charging mode is selected, the process enters the intelligent optimization charging stage. The system first reads all active usage plans, including single-use plans and recurring plans. For single-use plans, the system records the usage time on a specific date; for recurring plans, it needs to parse the recurrence rules, such as Monday, Wednesday, and Friday at 08:00, Tuesday and Thursday at 19:30, and Saturday at 09:00. Next, the system can integrate all usage time requirements to generate a complete usage calendar. Afterwards, it can obtain the dynamic preferential electricity price range and perform intelligent conflict detection. If a conflict is detected in the vehicle usage time, the system can prioritize the earliest usage time and adjust the charging strategy; if there is no conflict, it can directly formulate the optimal charging plan based on the electricity usage time and electricity price information, and finally complete the charging.
