[0034] First, the energy consumption statistics and display method applied to a vehicle is described.

[0035] Specifically, Figure 1 A flow chart of a method for counting and displaying energy consumption applied to a vehicle provided in an embodiment of the present application.

[0036] like Figure 1 As shown, the energy consumption statistics and display method includes the following steps:

[0037] In step S101, historical travel data of the vehicle is obtained.

[0038] It can be understood that the embodiments of the present application can record and obtain the vehicle's historical travel data through the VCU, wherein the vehicle's historical travel data may include the vehicle's total energy consumption, vehicle driving energy consumption, air conditioning energy consumption, battery thermal management energy consumption, energy recovery energy and other energy consumption, etc.

[0039] In step S102, a central control trip report is generated based on historical trip data, and the vehicle's drivable mileage is estimated based on the content of the central control trip report, wherein the content of the central control trip report includes the vehicle's energy consumption distribution, this trip, the trip after the last charge, the average energy consumption of the first target trip, the average energy consumption of the second target trip, and the dynamic energy consumption.

[0040] Among them, dynamic energy consumption refers to the real-time changes in energy consumption of the vehicle during driving.

[0041] It can be understood that the central control trip report of the embodiment of the present application is a report on the vehicle's driving conditions generated through historical trip data, including the vehicle's energy consumption distribution, this trip, the trip after the last charge, the average energy consumption of the first target trip, the average energy consumption of the second target trip, and the dynamic energy consumption.

[0042] In an embodiment of the present application, the energy consumption distribution includes driving consumption percentage, air-conditioning system consumption percentage, other consumption percentage and energy recovery percentage, wherein the energy consumption distribution is calculated based on the total vehicle energy consumption, vehicle driving energy consumption, air-conditioning energy consumption, battery thermal management energy consumption, energy recovery energy and other energy consumption in historical travel data, and other energy consumption = total vehicle energy consumption - vehicle driving energy consumption - vehicle air-conditioning system energy consumption - battery thermal management energy consumption.

[0043] It can be understood that the embodiments of the present application can calculate other energy consumption based on various energy consumption conditions recorded in historical travel data, including total vehicle energy consumption, vehicle driving energy consumption, air conditioning energy consumption, battery thermal management energy consumption and energy recovery energy, that is, the remainder after deducting driving energy consumption, air conditioning system energy consumption and battery thermal management energy consumption from the total vehicle energy consumption.

[0044] In the embodiment of the present application, the calculation formulas for the average energy consumption of the first target trip and the average energy consumption of the second target trip are:

[0045]

[0046] Wa=Ea÷Sa*100

[0047] Among them, Ut is the total voltage of the load end of the power battery, It is the charge and discharge current of the power battery, ΔT is the operating cycle, Vt is the vehicle speed, Wa is the average energy consumption, Ea represents the total energy consumption, Sa represents the total mileage, and N represents the number of operating cycles.

[0048] It can be understood that the embodiment of the present application can calculate the average energy consumption of the first target trip and the average energy consumption of the second target trip through the above formula using the total voltage of the power battery load end, the power battery charge and discharge current, the program scheduling module operation cycle, and the real-time vehicle speed.

[0049] In an embodiment of the present application, the vehicle's drivable mileage is estimated based on the content of the central control trip report, including: calculating the vehicle's average energy consumption based on the data curve under the mileage label; calculating the drivable mileage based on the vehicle's average energy consumption and the available capacity of the power battery.

[0050] Among them, the mileage label is a data label provided in the embodiment of the present application, such as the "10km" mileage label and the "100km" mileage label. The user can view the energy consumption performance within a specific distance range by selecting the mileage label, which is not specifically limited here; the average energy consumption of the vehicle is calculated according to the data curve under the mileage label, and the formula Eav = (ΔE1*ΔL1+ΔE2*ΔL2+...+ΔEn*ΔLn) / (ΔL1+ΔL2+...+ΔLn) is used for calculation, where E is the average power consumption of each small section, and L is the mileage; the drivable mileage is calculated according to the average energy consumption of the vehicle and the available capacity of the power battery, and is calculated by: drivable mileage = (available capacity × nominal voltage) / (average power consumption in the last 10km / 100km) × 100.

[0051] It can be understood that the embodiment of the present application can use the mileage label to provide the user with a data curve of mileage that can be selected. The average energy consumption of the vehicle is calculated by the data curve and the formula Eav = (ΔE1*ΔL1+ΔE2*ΔL2+...+ΔEn*ΔLn) / (ΔL1+ΔL2+...+ΔLn), and the drivable mileage is then calculated by mileage = (available capacity×nominal voltage) / (average power consumption in the last 10km / 100km)×100.

[0052] In step S103, the content of the central control trip report and the drivable mileage are displayed on the central control screen of the vehicle.

[0053] It can be understood that after calculating the drivable mileage, the embodiment of the present application displays the content of the central control trip report and the drivable mileage on the central control screen of the vehicle, helping the driver to better understand the vehicle status and plan the trip reasonably.

[0054] In an embodiment of the present application, before the vehicle's central control screen displays the content of the central control trip report and the drivable mileage, it also includes: identifying the mileage label; selecting instantaneous energy consumption data according to the mileage label; and generating a data curve under the mileage label according to the instantaneous energy consumption data.

[0055] It can be understood that before the content of the central control trip report and the drivable mileage are displayed on the central control screen of the vehicle, the embodiment of the present application needs to identify the mileage label selected by the user, select the instantaneous energy consumption data within a specific distance range according to the selected mileage label, and generate the data curve under the mileage label through the corresponding instantaneous energy consumption data.

[0056] According to the energy consumption statistics and display method applied to vehicles proposed in the embodiment of the present application, by acquiring the historical travel data of the vehicle, a central control travel report is generated, and the vehicle's drivable mileage is estimated based on the content of the central control travel report. The content of the central control travel report and the drivable mileage are displayed on the central control screen of the vehicle. The user's power consumption information can be displayed in real time, and the mileage can be estimated. The energy consumption curve is presented and the information is estimated, which is convenient for the user to correct driving behavior, control energy consumption, and plan the itinerary.

[0057] Based on the above embodiment, the energy consumption statistics and display method will be described below through another embodiment. The above embodiment focuses on the application of vehicles, and the following embodiment focuses on the application of remote monitoring platforms. The incomplete parts between the embodiments can be referenced to each other. The energy consumption statistics and display method will be specifically described below, as follows:

[0058] Figure 2 A schematic flow chart of an energy consumption statistics and display method applied to a remote monitoring platform according to an embodiment of the present application.

[0059] like Figure 2As shown, the energy consumption statistics and display method applied to the remote monitoring platform includes the following steps:

[0060] In step S201, the travel control reports and drivable mileages of multiple vehicles are obtained.

[0061] Among them, the vehicle's control trip report and drivable mileage are collected and generated by the vehicle VCU and transmitted to T-BOX (Telematics BOX, vehicle networking terminal). T-BOX collects, stores and transmits various data information related to vehicle energy consumption and transmits it to the remote monitoring platform.

[0062] It can be understood that the embodiment of the present application collects, stores and transmits various data information related to vehicle energy consumption through T-BOX, and obtains the control travel reports and drivable mileage of multiple vehicles.

[0063] In step S202, a power consumption ranking of vehicles of the same type is generated based on the travel reports of multiple vehicles.

[0064] Among them, the power consumption ranking of the same model is compared according to the power consumption data of all the most recent trips of vehicles of the same model in the same area with travel data within one month, and ranked from small to large. The real ranking or the surpassing percentage value is displayed according to the sales volume of the model. For example, when the sales volume of the model is less than or equal to 500, the actual ranking limit can be set to 20. The top 20 will be sent their real rankings, and the rest will be sent their surpassing percentage values, such as "the average power consumption this time exceeds 80% of drivers of the same model". If the ranking is the same, parallel data will be sent. The ranking sending rules are set according to the specific situation and are not specifically limited here.

[0065] It can be understood that the embodiment of the present application can obtain the control travel reports and drivable mileage of multiple vehicles, compare them, and generate the power consumption ranking of the same model according to the ranking rules.

[0066] In step S203, the control trip report, the drivable mileage and the power consumption ranking are sent to the target terminal, wherein the target terminal displays the content of the control trip report, the drivable mileage and the power consumption ranking of the corresponding vehicle.

[0067] Among them, the target terminal is a mobile terminal used by the user, such as a mobile phone, smart watch, and other devices that can download the corresponding software.

[0068] It can be understood that the embodiments of the present application can transmit the vehicle's controlled trip report, drivable mileage and power consumption ranking to the target terminal, and the target terminal displays the content of the corresponding vehicle's controlled trip report, drivable mileage and power consumption ranking. The user can view the power consumption information and power consumption ranking of the corresponding trip through the mobile terminal, and can view the content of the vehicle's controlled trip report and drivable mileage, which is convenient for the user to correct driving behavior, control energy consumption, and plan the trip.

[0069] According to the energy consumption statistics and display method applied to the remote monitoring platform proposed in the embodiment of the present application, by obtaining the control trip reports and drivable mileage of multiple vehicles, the power consumption ranking of the same model is generated, and the control trip report, drivable mileage and power consumption ranking are sent to the target terminal. The user's power consumption information can be displayed in real time through the target terminal, and the mileage can be estimated. The energy consumption curve and estimated information can be presented for the convenience of user viewing, providing more possibilities for interaction with other owners of the same model. The display of power consumption ratio comprehensively and vividly shows the user's driving behavior in a specific trip and a specific long period.

[0070] The energy consumption statistics and display method is further described below through a specific embodiment, which will be described from two aspects: energy consumption calculation and display on the vehicle side and energy consumption calculation and display on the APP side, as follows:

[0071] 1. Vehicle-side energy consumption calculation and display

[0072] The energy consumption display of the central control driving report includes six parts. The energy consumption distribution includes vehicle driving energy, air conditioning energy, battery thermal management energy, energy recovery energy and other energy consumption. This trip displays the average energy consumption since power-on, the average energy consumption since the last charge, the average energy consumption of TripA, the average energy consumption of TripB, the instantaneous energy consumption and the estimated mileage, such as Figure 3 shown.

[0073] 1. Energy consumption distribution

[0074] (1) The total energy consumed by the vehicle is the total energy consumed by the battery. The total energy consumed is:

[0075] E Total =∫(I Total ×V3)

[0076] In the formula, I Total is the power battery discharge current, and V3 is the total load voltage of the power battery.

[0077] (2) The energy consumed by the vehicle while driving includes the energy consumed by the front and rear motors. The total energy consumed is:

[0078] E Drv =∫(I mot_f ×U mot_f +I mot_r ×U mot_r )

[0079] In the formula, I mot_f is the DC bus current before MCU, U mot_f is the DC bus voltage of the front MCU, I mot_r is the DC bus current of the post-MCU, U mot_ris the DC bus voltage of the rear MCU.

[0080] (3) The energy consumed by the vehicle air conditioning system includes heating energy and cooling energy. The total energy consumed is:

[0081] E H =E H_heat +E H_cool

[0082] The energy consumption for heating is:

[0083] E H_heat =∫(I WTC_H ×V3) or E H_heat =∫(I WTC ×V3)×ε2

[0084] The energy consumption for refrigeration is:

[0085] E H_cool =∫(I EAS ×V3)×ε2

[0086] In the formula, for the vehicle type I equipped with the air conditioning system water heating controller WTC_H is the current working current of WTC_H, for models with only a single water heating controller I WTC is the current working current of WTC, V3 is the total voltage V3 of the power battery load end, ∑I EAS is the current working current of EAS, and ε2 is the proportional coefficient of energy consumed by EAS in passenger cabin air conditioning.

[0087] (4) The energy consumed by battery thermal management includes heating energy and cooling energy. The total energy consumed is:

[0088] E B =E B_heat +E B_cool

[0089] The energy consumption for heating is:

[0090] E B_heat =∫(I WTC_B ×V3) or E B_heat =∫(I WTC ×V3)×ε1

[0091] The energy consumed for refrigeration is:

[0092] E B_cool =∫(I EAS ×V3)×ε1

[0093] In the formula, for the vehicle type I equipped with the power battery water heating controller WTC_Bis the current working current of WTC_B, for models with only a single water heating controller I WTC is the current working current of WTC, V3 is the total voltage V3 of the power battery load end, I EAS is the current working current of EAS, ε1 is the proportional coefficient of energy consumed by EAS in power battery thermal management, which is obtained through calibration.

[0094] (5) Other energy consumption of the vehicle = total energy consumption of the vehicle - energy consumption of vehicle driving - energy consumption of vehicle air conditioning system - energy consumption of battery thermal management

[0095] (6) Energy recovery energy is the accumulated amount of feedback current at the battery end. The recovered energy is:

[0096] E Res =∫(-I Res ×V3)

[0097] In the formula, I Res is the power battery discharge current (negative value), and V3 is the total load voltage of the power battery.

[0098] After calculating the energy consumed by vehicle driving, vehicle air conditioning, battery thermal management, and other vehicle energy consumption, the percentage formulas for each part are as follows:

[0099] Total energy consumed during a trip = "Energy consumed by vehicle driving" + "Energy consumed by vehicle air conditioning system" + "Energy consumed by battery thermal management" + "Other energy consumed by vehicle" + "Energy recovery energy"

[0100] Driving consumption percentage

[0101]

[0102]

[0103] Other consumption percentage = 100% - driving consumption percentage - air conditioning system percentage - battery thermal management consumption percentage

[0104]

[0105] 2. Average energy consumption calculation

[0106] The calculation of the average energy consumption of this trip starts when the vehicle is powered on and running. The calculation ends when the vehicle is powered off. The average energy consumption is accumulated for each trip since the last charge. The energy consumption is stored when the vehicle is powered off and read when the vehicle is powered on. If the charging status is slow charge or fast charge, the accumulation starts from zero. The user decides whether to reset the calculation for TripA or TripB. The average energy consumption calculation formula is unified as follows:

[0107]

[0108] Wa=Ea÷Sa*100

[0109] Among them, Ut is the total voltage of the power battery load end, It is the power battery charge and discharge current, ΔT is the program scheduling module operation cycle (temporarily 10ms), Vt is the real-time vehicle speed, Wa is the average energy consumption, unit kWh / 100km.

[0110] 3. Dynamic energy consumption display and mileage estimation

[0111] VCU periodically sends instantaneous energy consumption to ICC. Based on the ODO mileage information, ICC memorizes the instantaneous energy consumption data of the vehicle's most recent 10km and 100km, plots it into a two-dimensional graph for display, and continuously updates it as the vehicle's mileage increases. At the same time, ICC provides two labels, "10km" and "100km", on the driving report interface for users to click and choose: when the user clicks the "10km" label, ICC displays the instantaneous energy consumption data curve of the user's vehicle in the last 10km; when the user clicks the "100km" label, ICC displays the instantaneous energy consumption data curve of the user's vehicle in the last 100km, such as Figure 4 shown.

[0112] The average power consumption formula calculated based on instantaneous energy consumption is as follows:

[0113] Eav=(ΔE1×ΔL1+ΔE2*ΔL2+...+ΔEn×ΔLn) / (ΔL1+ΔL2+...+ΔLn)

[0114] In the formula, E is the average power consumption of each segment, and L is the mileage.

[0115] The remaining driving range is based on the available capacity of the power battery and the average power consumption value calculated above:

[0116] Remaining driving range = (available capacity × nominal voltage) / (average power consumption in the last 10 km / 100 km) × 100.

[0117] The above calculation results need to judge different calculation starting conditions and termination conditions based on different presentation contents, as shown in Table 1, which is a correspondence table between presentation contents and judgment conditions.

[0147] In the formula, for the vehicle type I equipped with the power battery water heating controller WTC_B is the current working current of WTC_B, for models with only a single water heating controller I WTC is the current working current of WTC, V3 is the total voltage V3 of the power battery load end, I EAS is the current working current of EAS, and ε1 is the proportional coefficient of the energy consumed by EAS in the thermal management of power batteries. The parameter values ​​of ε1 and ε2 are shown in Table 2 below, which is a corresponding table of the parameter values ​​of ε1 and ε2 and the wind speed state and the thermal management requirements of power batteries.

[0148] Table 2

[0149] Serial number Wind speed status Power battery thermal management requirements <![CDATA[ε1]]> <![CDATA[ε2]]> 1 No wind speed / 1 0 2 With wind speed No demand 0 1 3 With wind speed Cooling demand / heating demand 0.3 0.7

[0150] Other energy consumption of the vehicle = total energy consumption of the vehicle - energy consumption of vehicle driving - energy consumption of vehicle air conditioning system - energy consumption of battery thermal management. This value needs to be processed as the maximum and minimum values ​​according to the DCDC working power [0.2,1.5] kW. When other energy consumption of the vehicle exceeds the maximum and minimum value range, the maximum and minimum values ​​are taken. The overflow value or loss value is taken as the vehicle driving energy consumption for addition and subtraction.

[0151] The energy recovery energy is the accumulated amount of the feedback current at the battery end. The recovery energy is:

[0152] E res =∫(-I Res ×V3)

[0153] In the formula, I Res is the power battery discharge current (negative value), and V3 is the total load voltage of the power battery.

[0154] The monthly (weekly) power consumption is calculated by the total energy consumed by the vehicle and the total monthly (weekly) mileage. The calculation formula is as follows:

[0155] Total vehicle energy consumption = sum ("vehicle driving energy consumption", "vehicle air conditioning system energy consumption", "battery thermal management energy consumption" and "vehicle other energy consumption" of all monthly (weekly) trips)

[0156] Monthly (weekly) average power consumption = total energy consumption this month ÷ sum of all mileage values ​​this month × 100

[0157] 2. Power consumption ratio

[0158] (1) Ranking of power consumption for this trip: All the power consumption data of the most recent trip of vehicles of the same model with trip data within one month in the same region (currently defined as nationwide, and can be divided by city in the future) are compared and ranked from small to large. The top 100 (recommended value, when the sales volume of the model is greater than 1,000, the actual ranking limit is 100; when the sales volume of the model is less than or equal to 1,000 and greater than 500, the actual ranking limit is 50; when the sales volume of the model is less than or equal to 500, the actual ranking limit is 20) will be issued their actual rankings, and the rest will be issued their exceeding percentage values, such as "the average power consumption this time exceeds 80% of Alpha T car owners". If the rankings are the same, the parallel data will be issued. The issued rankings will be rounded to the nearest integer, and will not be issued repeatedly after the vehicle use report is formed.

[0159] (2) "Monthly trip" ranking: Same as the current trip power consumption ranking, Cheyun will compare the average power consumption of the vehicle this month with the recent average power consumption of the same model in the same region (currently defined as nationwide, and can be divided by city in the future), ranking from small to large, and the top 100 (recommended value, when the sales volume of the model is greater than 1,000, the actual ranking limit is 100; when the sales volume of the model is less than or equal to 1,000 and greater than 500, the actual ranking limit is 50; when the sales volume of the model is less than or equal to 500, the actual ranking limit is 20) will be issued with their actual ranking, and the rest will be issued with their surpassing percentage values, such as "this month's average power consumption ranks first among Alpha T car owners". If the ranking is the same, the parallel data will be issued. The issued ranking number will be rounded to the nearest integer, and will not be issued repeatedly after the vehicle usage report is formed.

[0160] 3. Power consumption distribution

[0161] The power consumption distribution includes the percentage of energy consumed by vehicle driving, the percentage of energy consumed by the vehicle air conditioning system, the percentage of energy consumed by battery thermal management, and the percentage of energy recovery. The calculation rules are as follows:

[0162] Total energy consumption of the trip = "energy consumed by vehicle driving" + "energy consumed by vehicle air conditioning system" + "energy consumed by battery thermal management" + "other energy consumed by vehicle" + "energy recovery energy".

[0163]

[0164] Other consumption percentage = 100% - driving consumption percentage - air conditioning system percentage - battery thermal management consumption percentage

[0165]

[0166] After obtaining the vehicle driving consumption, air conditioning system consumption and battery thermal management percentage, Cheyun Cloud rounds off and takes the integer. The other consumption percentages are obtained by subtracting the above three percentages from 100%, and the energy recovery percentage is also rounded off. Finally, Cheyun sends the calculated percentage value to the APP. The calculation rules for the power consumption distribution of "this month's data" refer to the calculation rules for the power consumption distribution of this trip (as above), accumulating the monthly driving power consumption, air conditioning system power consumption, battery thermal management power consumption and energy recovery energy of all trips, summing them up and substituting them into the calculation.

[0167] In addition, in the following special travel situations, the vehicle driving consumption percentage, air conditioning system consumption percentage, battery thermal management consumption percentage and vehicle other consumption percentages are specially marked: if the vehicle driving energy consumption is 0, the vehicle driving consumption percentage, air conditioning system consumption percentage, battery thermal management consumption percentage and vehicle other consumption percentages are not issued, and the energy recovery percentage is equal to 100%.

[0168] like Figure 5 As shown, VCU calculates the power consumption and displays relevant information. When the vehicle determines that the vehicle trip is over, it transmits the power consumption information to TBOX. If TBOX determines that the trip is valid, it uploads it to the platform. Users can view the power consumption information of each trip within the month through the APP.

[0185] It should be noted that the above explanations of the embodiment of the energy consumption statistics and display method are also applicable to the energy consumption statistics and display device of this embodiment, and will not be repeated here.
