[0087] After introducing the basic principles of this application, various non-limiting embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0088] Example 1
[0089] like Figure 1 As shown, this application provides a method for predicting temperature and thermal management energy consumption based on navigation charging. The method is applied to a prediction system for temperature and thermal management energy consumption based on navigation charging. The system is communicatively connected to a BMS (Battery Management System), and the BMS includes a SOC (State of Charge) module, a remaining time module, and an intelligent temperature control module. The method specifically includes the following steps:
[0090] Step S100: Calculate the BMS of the first vehicle in the power-on update state according to the SOC module, and send the first cycle information;
[0091] Specifically, the SOC module is a module for calculating the state of charge (SOC) of the battery, wherein the SOC refers to a state of charge parameter of the battery. The first vehicle is a new energy vehicle. The power-on update state is a state of the vehicle in a power-on timing after power-on. The first period information refers to BMS calculated by the SOC module in the power-on update state of the vehicle, and specifically includes: current available energy, 80% SOC available energy, safe energy, and energy corresponding to a user-set destination SOC. The BMS in the power-on update state is obtained, thereby providing basic data for subsequent prediction of the temperature and thermal management energy consumption of the first vehicle in a navigation state.
[0092] Preferably, the current available energy is the available energy of the current state of the power battery, the 80% SOC available energy is 80%*maximum available energy at the current temperature, the safe energy is 20%*maximum available energy at the current temperature, and the energy corresponding to the user-set destination SOC is user-set destination SOC / conversion factor*maximum available energy at the current temperature.
[0093] Step S200: Real-time collection of a first state of the first vehicle, and determination of whether the first state conforms to a first preset navigation state, wherein the first preset navigation state is a set navigation state in a navigation state.
[0094] Specifically, the first state refers to a vehicle control state of the first vehicle at a current time. The first state of the first vehicle is collected in real time, and it is determined whether the vehicle is in the first preset navigation state. The first preset navigation state is a set navigation state in a navigation state. It is determined whether the vehicle starts navigation and is ready to reach the next station or destination, thereby achieving the technical effect of laying a foundation for subsequent management of charging of the vehicle based on navigation.
[0095] Step S300: If the first state conforms to the first preset navigation state, collecting a first route station selection plan, and determining whether the first vehicle is currently performing station selection according to the first route station selection plan.
[0096] Specifically, it is determined whether the first vehicle is in a state of starting navigation and being ready to reach the next station or destination, the first route station selection plan is collected, and it is determined whether the first vehicle is currently performing station selection according to whether there is a station selection flag in the first route station selection plan. The first route station selection plan is plan information of a route and station selection of the user when setting vehicle navigation information. Thus, the technical effect of providing basic data for subsequent further analysis of the state of the first vehicle is achieved.
[0097] Step S400: If the first vehicle is currently in the process of selecting a pile, the first period information is calculated and updated by using the SOC module and the remaining time module to obtain second period information;
[0098] Specifically, it is judged that the first vehicle is currently in the process of selecting a pile, which indicates that the first vehicle has a demand for charging. Therefore, the first period information is calculated and updated by using the SOC module and the remaining time module to obtain the second period information. The second period information is the BMS of the first vehicle in the state of pile selection calculation, including the remaining SOC of each pile, the SOC of reaching the destination when there is a planned pile, and the charging time of each pile. The remaining time module is a calculation module of the charging time calculated according to the slow charging remaining time. The technical effect of improving the vehicle operation stability and reliability is achieved by reliably predicting the temperature and thermal management energy consumption during charging according to different states of the first vehicle.
[0099] Preferably, the remaining SOC of reaching each pile is the remaining SOC (SOCDOWN) of reaching the jth pile, where j is a positive integer greater than or equal to 2. The SOC of reaching the destination when there is a planned pile is the SOC of reaching the destination when there are i planned piles, and i is a positive integer greater than or equal to 1. The charging time of each pile is the charging time calculated according to the slow charging remaining time when the maximum charging capacity of the charging pile is less than 20A.
[0100] Step S500: Real-time collection and update of the first state to obtain a second state, and judging whether the second state conforms to a second preset navigation state, wherein the second preset navigation state is a start navigation state in a navigation state;
[0101] Specifically, the second state is the state of the first vehicle obtained by real-time collection and update of the first state. The judgment of whether the second state conforms to the second preset navigation state is used to judge whether the first vehicle has started to depart for the destination or plan a pile. The second preset navigation state is a start navigation state in a navigation state. Therefore, the technical effect of laying a foundation for further analysis and prediction of the temperature and thermal management energy consumption of the first vehicle when reaching the destination is achieved.
[0102] Step S600: If the second state conforms to the second preset navigation state, the second period information is calculated and updated by using the SOC module and the remaining time module to obtain third period information;
[0103] Specifically, if the second state matches the second preset navigation state, it indicates that the first vehicle starts to navigate to a destination. The second period information is calculated and updated by the SOC module and the remaining time module to obtain third period information. The third period information is the BMS of the first vehicle in the starting navigation state, including the remaining SOC of the next stake in navigation or the remaining SOC to the destination, the charging cutoff SOC of the next stake in navigation, and the charging time of the next stake in navigation. The BMS of the first vehicle in the starting navigation state is obtained, and the technical effect of further improving the accuracy of predicting the temperature and thermal management energy consumption of the charging is achieved.
[0104] Preferably, the remaining SOC of the next stake in navigation or the remaining SOC to the destination is the remaining SOC to each stake. The charging cutoff SOC of the next stake in navigation is the upper limit of the charging SOC. The charging time of the next stake in navigation is the charging time calculated according to the slow charging remaining time when the maximum charging capacity of the next charging stake is <20A during navigation.
[0105] Step S700: analyzing the third period information by using the intelligent temperature control module to generate first prediction information.
[0106] Specifically, the intelligent temperature control module refers to a module for analyzing and predicting the temperature and battery thermal management energy consumption. The first prediction information refers to the battery temperature and thermal management energy consumption information predicted by analyzing the information obtained based on the navigation state of the first vehicle. Thus, the temperature and thermal management energy consumption are predicted in real time based on the user navigation information, intelligent and accurate navigation planning is provided for user navigation, the accuracy of navigation is improved, and the technical effect of improving the stability and service life of automobile operation is achieved.
[0107] Further, as shown in Figure 2 If the first state matches the first preset navigation state, the first route selection stake planning is collected before the step 300 of the embodiment of the application further includes:
[0108] If the first state matches the first preset navigation state, the first period information is calculated and updated by using the SOC module to obtain fourth period information.
[0109] The fourth period information refers to the BMS of the first vehicle in the setting navigation state, and the fourth period information is calculated by the SOC module.
[0110] Specifically, when the first vehicle is in a start navigation state, the first period information is updated by the SOC module to obtain the fourth period information. The fourth period information refers to the BMS of the first vehicle in a set navigation state. The fourth period information includes: SOC of reaching the destination without selecting a pile, and remaining SOC after returning. Thus, the SOC of reaching the destination and the remaining SOC after returning can be obtained without planning to charge in the middle, thereby better planning the navigation of the first vehicle.
[0111] Specifically, the fourth period information is calculated by the SOC module and includes:
[0112] The calculation formula of the SOC (SOCE) of reaching the destination without selecting a pile is:
[0113] SOCE = SOC0 - ΔSOC
[0114] Wherein, ΔSOC is the road consumption SOC of reaching the destination, which is obtained by converting the road consumption energy.
[0115] The calculation formula of the remaining SOC (SOCEE) after returning is:
[0116] SOCEE = SOC0 - 2*ΔSOC
[0117] Wherein, SOC0 is the initial SOC.
[0118] Further, as shown in the SOC module and the remaining time module, the first period information is updated to obtain the second period information, and the step S400 of the embodiment of the application further includes: Figure 2
[0119] Step S410: calculating the BMS of the first vehicle by the SOC module to obtain the first information;
[0120] Step S420: calculating the BMS of the first vehicle by the remaining time module to obtain the second information;
[0121] Step S430: according to the first information and the second information, the second period information is composed, wherein the second period information refers to the BMS of the first vehicle in the selected pile calculation state.
[0122] Specifically, the first information is the remaining SOC upon reaching each charging station and the SOC upon reaching the destination when there are planned charging stations; the second information is the charging time for each charging station. Through the SOC module and the remaining time module, the SOC and charging time information can be accurately calculated, achieving the technical effect of providing accurate data for subsequent analysis of the battery temperature and thermal management energy consumption of the first vehicle.
[0123] Specifically, this also includes obtaining the remaining SOC (Sodium Calibration) reaching each stake. j The calculation process of ) is as follows:
[0124] Remaining SOC for the first charging station:
[0125] SOCDOWN1=SOC0-ΔSOC1
[0126] The remaining SOC of the j-th (2≤j≤i) charging pile
[0127] (SOCDOWN j ) = min(SOCUP j-1 -ΔSOC j )
[0128] Wherein, ΔSOC j The SOC consumed by the j-th segment.
[0129] Calculate the upper limit of charging SOC (SOCUP) j :
[0130] i represents the number of charging stations selected. When the charging station is not the last charging station (i.e., the j-th station, j≤i-1):
[0131] SOCUP j =min(ΔSOC) j+1 +20%, 100%
[0132] Wherein, ΔSOC j+1 For the road consumption SOC after passing the j-th charging pile, the last charging pile, i.e., j=i:
[0133] [SOCUP j =minΔSOC j+1 +max(20%, user-defined SOC), 100%]
[0134] The formula for calculating the State of Charge (SOC) upon reaching the destination when there are planned stakes is as follows:
[0135] SOCE = SOCUP j=i -ΔSOC j=i+1
[0136] Where i represents the number of planned stakes, and 1 ≤ j ≤ i.
[0137] The calculation formula for obtaining the charging time of each pile is:
[0138] The remaining charging time t(i) of the i-th pile is:
[0139] t(i) = t[min(SOCSET, SOCUP i )] - t(SOCDOWN i ),
[0140] Wherein, SOCSET is the user-set SOC.
[0141] Further, as shown in Figure 3 the embodiment of the present application, after the second period information is composed according to the first information and the second information, step S430 further includes:
[0142] Step S431: analyzing the second period information by using the intelligent temperature control module to obtain a first analysis result;
[0143] Step S432: generating second prediction information according to the first analysis result, wherein the second prediction information includes the prediction of the temperature and thermal management energy consumption of the first vehicle in the selected pile calculation state.
[0144] Specifically, the first analysis result includes the temperature prediction value of each pile and the battery thermal management energy consumption of each section of road. The second prediction information includes the prediction of the temperature and thermal management energy consumption of the first vehicle in the selected pile calculation state. Thus, the vehicle battery temperature and thermal management energy consumption in the selected pile calculation state are obtained, and the technical effect of improving the prediction accuracy is achieved.
[0145] Specifically, the analysis of the second period information by using the intelligent temperature control module further includes obtaining the calculation and analysis process of the temperature prediction value of each pile:
[0146] If the remaining SOC of the planned charging pile is > 20%, the environmental temperature is ≤ 15℃, and the battery temperature of the charging pile is 20℃;
[0147] If the remaining SOC of the planned charging pile is > 20%, the environmental temperature is > 15℃, and the battery temperature of the charging pile is 30℃;
[0148] If the remaining SOC of the planned charging pile is 0 < SOC < 20%, the environmental temperature is ≤ 15℃, and the battery thermal management energy consumption is ≤ 0, the battery temperature of the charging pile is 20℃;
[0149] If the remaining SOC is 0<SOC<20% when arriving at the planned charging pile, the ambient temperature is ≤15℃, and the power battery thermal management energy consumption is >0, then the battery temperature when arriving at the charging pile is:
