[0037] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0038] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0039] To address existing technical problems, in some embodiments of this application, the system receives vehicle charging demand information; receives the vehicle's target charging capacity and the ratio of expected charging cost to expected charging time; determines the expected charging cost and expected charging time based on the target charging capacity and the ratio of expected charging cost to expected charging time; determines the actual control sequence for actual charging control of the vehicle based on the target charging capacity, expected charging cost, and expected charging time; and obtains the control sequence matching the user's charging demand information to control the vehicle's charging, thereby improving the intelligence level of vehicle charging control.

[0040] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0041] Figure 1 This is a schematic diagram of the structure of a vehicle charging system 10 provided in an example embodiment of this application. Figure 1 As shown, the vehicle charging system 10 includes a vehicle 10a and a server 10b.

[0042] In this embodiment, the connection between vehicle 10a and server 10b can be wireless or wired. Optionally, vehicle 10a can establish a communication connection with server 10b using wireless communication technologies (WIFI), Bluetooth, infrared, etc., or vehicle 10a can also establish a communication connection with server 10b through a mobile network. The mobile network standard can be any one of the following: Global System for Mobile Communications (GSM, 2G), General Packet Radio Service (GPRS, 2.5G), Wideband Code Division Multiple Access (WCDMA, 3G), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA, 3G), CDMA2000, UTMS (Universal Mobile Telecommunications System, 3G), Long Term Evolution (LTE, 4G), World Interoperability for Microwave Access (WiMAX), etc.

[0043] In this embodiment, an electronic display screen is provided on the vehicle 10a. This application does not limit the type of electronic display screen; for example, it could be a central control screen or a head-up display. The electronic display screen can display user charging needs information, vehicle status, and vehicle charging information. In this embodiment, the vehicle 10a can be an electric vehicle or a hybrid electric vehicle.

[0044] In this embodiment, the user inputs the target charging amount and the ratio of the expected charging cost to the expected charging time through the electronic display screen of vehicle 10a. Vehicle 10a sends the target charging amount and the ratio of the expected charging cost to the expected charging time to server 10b. Server 10b determines the specific values ​​of the expected charging cost and the expected charging time based on the ratio of the target charging amount and the expected charging cost to the expected charging time. Then, based on the target charging amount, the expected charging cost, and the expected charging time, it determines the control sequence for actual charging control of the vehicle; and during the charging process, it calculates the current actual charging cost in real time.

[0045] In this embodiment, server 10b uses the target charging capacity and the ratio of expected charging cost to expected charging time to determine the specific values ​​of the expected charging cost and expected charging time. Then, based on the target charging capacity, expected charging cost, and expected charging time, it determines the control sequence for actual charging control of the vehicle. In this embodiment, the implementation form of server 10b is not limited; for example, server 10b can be a conventional server, cloud server, cloud host, virtual center, or other server equipment. The main components of server 10b include a processor, hard disk, memory, system bus, and other common computer architecture types.

[0046] In this embodiment, the electronic display screen of vehicle 10a displays an interface, which includes two input elements: a target charging amount for charging the vehicle and a ratio between the expected charging cost and the expected charging time. In response to the operation of the target charging amount and the ratio between the expected charging cost and the expected charging time, the expected charging cost and the expected charging time for charging the vehicle are obtained.

[0047] In the above embodiments of this application, there are two information input elements; vehicle 10a responds to the operation of the ratio of target charging capacity, expected charging cost and expected charging time, and sends the ratio of target charging capacity, expected charging cost and expected charging time to server 10b. Server 10b obtains the current driving data of the vehicle; based on the current driving data, target charging capacity and ratio, it determines the expected charging cost and expected charging time, and sends the expected charging cost and expected charging time to vehicle 10a.

[0048] In one possible implementation, the information input elements include a target charging level slider and a time cost-related slider. The vehicle 10a responds to a drag operation on the target charging level slider to obtain the target charging level; and responds to a drag operation on the time cost-related slider to obtain the ratio between the expected charging cost and the expected charging time.

[0049] Furthermore, the information input elements include a target charging capacity slider and a time cost associated slider, which can be arranged vertically or vertically.

[0050] Figure 2 This is a schematic diagram of a charging demand input interface (the interface described above) provided for an exemplary embodiment of this application. For example... Figure 2 As shown, the charging demand input interface includes a charging capacity slider and a slider showing the relationship between charging cost and charging time. It may also include a time cost display area and a vehicle status display area. This application embodiment does not limit the overall layout of the charging demand input interface. Figure 2In the interface, the charging power slider and the charging cost vs. charging time slider can be located in the lower area, while the charging cost vs. charging time slider should be positioned above the charging power slider. The vehicle status display area can show the vehicle's real-time status, and the time cost display area can show the estimated charging time and estimated charging cost.

[0051] After receiving the estimated charging time and estimated charging cost from server 10b, vehicle 10a displays the estimated charging time and estimated charging cost on an electronic display screen. The user can view the charging demand information to decide whether to charge the vehicle. If charging is required, vehicle 10a responds to the user-initiated charging operation and executes the charging operation.

[0052] It should be noted that the specific implementation of the charging capacity slider and the charging cost vs. charging time slider in this application embodiment is not limited. The charging capacity slider can be a slider for adjusting the vehicle's charging percentage or a slider for adjusting the vehicle's charging capacity; the leftmost position of the charging cost vs. charging time slider can be the position corresponding to the lowest charging cost and longest charging time, and the rightmost position of the charging cost vs. charging time slider can be the position corresponding to the highest charging cost and shortest charging time; conversely, the leftmost position of the charging cost vs. charging time slider can be the position corresponding to the highest charging cost and shortest charging time, and the rightmost position of the charging cost vs. charging time slider can be the position corresponding to the lowest charging cost and longest charging time.

[0053] In this embodiment, after obtaining the first charging demand information and the second charging demand information, vehicle 10a sends the first charging demand information and the second charging demand information to server 10b. Server 10b obtains the first charging demand information and the second charging demand information for charging the vehicle, wherein the first charging demand information and the second charging demand information are any two of the target charging capacity, the estimated charging time, and the estimated charging cost. Based on the first charging demand information and the second charging demand information, a third charging demand information for charging the vehicle is determined, wherein the third charging demand information is the remaining charging demand information other than the first demand information and the second demand information among the target charging capacity, the estimated charging time, and the estimated charging cost.

[0054] In one optional embodiment, the first demand information is the target charging capacity, the second charging demand information is the estimated charging time, and the third charging demand information is the estimated charging cost. Then, server 10b determines the third charging demand information for charging the vehicle based on the first and second charging demand information. One possible implementation method is to calculate a charging current sequence for charging the vehicle based on the target charging capacity, estimated charging time, and charging pile power, wherein the charging current sequence is a sequence of control signals sent to the battery during vehicle charging; and to calculate a thermal management control sequence for charging the vehicle based on the charging current sequence, wherein the thermal management control sequence is a sequence of control signals sent to components related to regulating battery coolant temperature during vehicle charging; calculate the battery charging cost based on the charging current sequence; and calculate the accessory consumption cost based on the thermal management control sequence; and calculate the estimated charging cost for charging the vehicle based on the battery charging cost and accessory consumption cost; wherein the accessory consumption cost includes the consumption cost of at least one component among the compressor, pressure transmitter, three-way valve, heater pump, electric fan, solenoid valve, battery water pump, and four-way valve.

[0055] In the above embodiments, the estimated charging cost of charging the vehicle is calculated based on the battery charging cost and accessory consumption cost. One possible approach is to calculate the estimated charging cost of charging the vehicle based on the battery charging cost, accessory consumption cost, parking cost, additional electricity cost, and service cost. The additional electricity cost is the fixed electricity loss cost required for one charging cycle, and the service cost is the fixed service fee required for one charging cycle. The additional electricity cost is the fixed electricity loss cost per unit time. For example, if the electricity loss cost is 2 yuan per hour, then for 2 hours of charging, the electricity loss cost is 2 * 3 = 6 yuan. The service cost is a fixed value; for one charging cycle, the service fee is fixed at 3 yuan and is independent of the charging time.

[0056] In another optional embodiment, the first demand information is the target charging capacity, the second charging demand information is the estimated charging cost, and the third charging demand information is the estimated charging time. Then, server 10b determines the third charging demand information for charging the vehicle based on the first and second charging demand information. One possible approach is to calculate the first charging time for charging the vehicle based on the estimated charging cost and the target charging capacity; and to determine the estimated charging time for charging the vehicle based on the first charging time, the target charging capacity, and the power of the charging pile.

[0057] In the above embodiment, server 10b determines the estimated charging time for charging the vehicle based on the first charging time, the target charging capacity, and the power of the charging pile. One possible implementation is to calculate the first charging cost for charging the vehicle based on the first charging time, the target charging capacity, and the power of the charging pile; and determine the estimated charging time for charging the vehicle based on the relationship between the difference between the first charging cost and the estimated charging cost and a set threshold. If the difference is less than the set threshold, the first charging time is used as the estimated charging time; if the difference is greater than or equal to the set threshold, the process is repeated to predict the charging cost for charging the vehicle using the estimated charging time, the target charging capacity, and the power of the charging pile, until the difference between the second charging cost and the estimated charging cost is less than the set threshold, at which point the charging time corresponding to the second charging cost is used as the estimated charging time.

[0058] In the above embodiments, the first charging cost of charging the vehicle is calculated based on the first charging time, the target charging capacity, and the power of the charging pile. One possible implementation is to calculate the charging current sequence for charging the vehicle based on the target charging capacity, the first charging time, and the power of the charging pile, wherein the charging current sequence is a sequence of control signals sent to the battery during vehicle charging; and to calculate the thermal management control sequence for charging the vehicle based on the charging current sequence, wherein the thermal management control sequence is a sequence of control signals sent to components related to regulating the battery coolant temperature during vehicle charging; to calculate the battery charging cost based on the charging current sequence; and to calculate the accessory consumption cost based on the thermal management control sequence; and to calculate the first charging cost of charging the vehicle based on the battery charging cost and the accessory consumption cost; wherein the accessory consumption cost includes the consumption cost of at least one component among the compressor, pressure transmitter, three-way valve, heater pump, electric fan, solenoid valve, battery water pump, and four-way valve.

[0059] In the above embodiment, after calculating the estimated charging time or estimated charging cost, server 10b sends the estimated charging time or estimated charging cost to vehicle 10a, so that the estimated charging time and estimated charging cost can be displayed on the electronic display screen of vehicle 10a. The user then decides whether to charge based on the estimated charging time or estimated charging cost.

[0060] After server 10b takes any two of the demand information from the target charging capacity, the estimated charging cost, and the estimated charging time as the first charging demand and the second charging demand, it determines the actual control sequence for actual charging control of the vehicle based on the first charging demand information and the second charging demand information. The actual control sequence is a sequence of control signals sent to the charging-related components of the vehicle during charging.

[0061] In the above embodiments, server 10b simulates the charging process of the vehicle based on the first charging demand information and the second charging demand information to obtain an actual control sequence for actual charging control of the vehicle. One possible approach is to optimize the vehicle control sequence based on the first charging demand information and the second charging demand information to obtain a simulation control sequence for simulated charging control of the vehicle; and to determine the actual control sequence for actual charging control of the vehicle based on the simulation results of the vehicle charging process using the simulation control sequence.

[0062] Specifically, based on the first and second charging demand information, a simulation control sequence for simulating vehicle charging is obtained. One possible approach is to utilize a multi-objective control algorithm, using the first and second charging demand information as objectives, to obtain the simulation control sequence for simulating vehicle charging.

[0063] The process involves determining the actual control sequence for vehicle charging based on the simulation results of the vehicle charging process using a simulated control sequence. One possible approach is to simulate the vehicle charging process using the simulated control sequence to obtain first simulated charging information, which corresponds to the target charging capacity, estimated charging time, and estimated charging cost. A judgment result is generated based on whether the first simulated charging information matches first and second charging demand information. Based on the judgment result, the actual control sequence for vehicle charging is determined. It should be noted that the first simulated charging information includes the simulated charging time, simulated charging cost, and simulated charging capacity corresponding to the estimated charging time, estimated charging cost, and target charging capacity, respectively. To determine whether the first simulated charging information matches the first charging demand information and the second charging demand information, when the first and second charging demand information are the expected charging time and the target charging capacity, the difference between the expected charging time and the simulated charging time can be used to determine whether the first simulated charging information matches the first charging demand information and the second charging demand information. If the difference between the expected charging time and the simulated charging time is less than the first threshold and the difference between the target charging capacity and the simulated charging capacity is less than the second threshold, then the first simulated charging information matches the first charging demand information and the second charging demand information; otherwise, the first simulated charging information does not match the first charging demand information and the second charging demand information. When the first and second charging demand information are the expected charging cost and the target charging capacity, and when the first and second charging demand information are the expected charging cost and the expected charging time, the same method can be used to determine whether the first simulated charging information matches the first charging demand information and the second charging demand information.

[0064] In the above embodiments, if the determination result is a match, the simulated control sequence is used as the actual control sequence for actual charging control of the vehicle. At this time, the third charging demand information is determined from the first simulated charging information. The third charging demand information can be displayed before charging, after the user inputs the first and second charging demand information, or it can be displayed during the charging process.

[0065] In the above embodiments, if the judgment result is a mismatch, the calculation simulation control sequence is updated until the target simulation charging information matches the first charging demand information and the second charging demand information, and the target simulation control sequence corresponding to the target simulation charging information is used as the actual control sequence for actual charging control of the vehicle.

[0066] In another feasible approach, a simulated control sequence is input into a charging demand prediction model to obtain first simulated charging information. The training steps for the charging demand prediction model are as follows: collect control sequence samples and charging demand information samples; train the model based on the control sequence samples and charging demand information samples to obtain the charging demand prediction model.

[0067] During the actual charging control of vehicle 10a, vehicle 10a returns actual charging information to server 10b. The server uses this information to further optimize the control sequence, obtaining a new control sequence. One possible approach is to receive the actual charging information returned by the vehicle; optimize the vehicle's control sequence based on the information to obtain a third simulated control sequence for charging the vehicle; simulate the charging process using this third simulated control sequence to obtain a new control sequence for actual charging control; and send this new control sequence to the vehicle so that it can control its charging according to the new sequence.

[0068] In this embodiment, during the entire charging process of vehicle 10a, server 10b sends a control sequence for charging control of vehicle 10a to vehicle 10a in real time. Server 10b obtains the thermal management control sequence and charging current sequence for the actual charging control of the vehicle; server 10b determines the actual charging cost of charging the vehicle based on the thermal management control sequence and charging current sequence. Server 10b calculates the actual charging cost at any time during the charging process in real time.

[0069] In the above embodiment, after determining the actual charging cost of charging the vehicle based on the thermal management control sequence and the charging current sequence, the server 10b sends the actual charging cost to the vehicle 10a. The vehicle 10a displays the actual charging cost for the user to view. The actual charging cost can be the charging cost at any time during the charging process.

[0070] In the above embodiments, server 10b determines the actual charging cost of charging the vehicle based on the thermal management control sequence and the charging current sequence. One possible implementation is that server 10b obtains the accessory consumption cost based on the thermal management control sequence; server 10b obtains the actual battery charging cost based on the charging current sequence; server 10b determines the actual charging cost of charging the vehicle based on the accessory consumption cost and the actual battery charging cost. For example, server 10b obtains the consumption cost of each component based on the thermal management control sequence to obtain the total accessory consumption cost; server 10b calculates the actual battery charging cost based on the charging current sequence and the charging time sequence corresponding to each charging current sequence.

[0071] In the above embodiment, server 10b determines the actual charging cost of charging the vehicle based on the cost of accessories consumed and the actual charging cost of the battery. One possible implementation is that server 10b calculates the actual charging cost of charging the vehicle based on the cost of accessories consumed, the actual charging cost of the battery, parking costs, additional electricity costs, and service costs. For example, parking costs can be calculated using the parking unit price and parking duration; a single charging process for vehicle 10a requires the payment of a preset service fee and additional electricity fee, which are considered service costs and additional electricity costs.

[0072] It should be noted that the cost of accessories includes the cost of at least one of the following components when operating according to the thermal management control sequence: compressor, pressure transmitter, three-way valve, heater pump, electric fan, solenoid valve, battery pump, and battery four-way valve.

[0073] In the above system embodiments of this application, the first position of the first slider on the charging power slider and the second position of the second slider on the charging cost versus charging time slider are obtained. Based on the first and second positions, the estimated charging time and estimated charging cost for the vehicle are predicted. Users can set the target charging power, estimated charging time, and estimated charging cost by dragging the positions of the sliders on the charging power slider and the charging cost versus charging time slider. Users can balance the charging time and charging cost for the vehicle, thus improving the user experience.

[0074] During the actual charging process of vehicle 10a, server 10b determines the actual charging cost of charging the vehicle based on the acquired actual charging control sequence. This actual charging cost can be sent to the vehicle by server 10b for real-time display during the user's charging process.

[0075] The actual charging sequence includes a thermal management control sequence and a charging current sequence. The actual charging cost of the vehicle is determined based on these sequences. One possible approach is to obtain the accessory consumption cost based on the thermal management control sequence; obtain the actual battery charging cost based on the charging current sequence; and determine the actual charging cost of the vehicle based on both the accessory consumption cost and the actual battery charging cost. Optionally, the actual charging cost of the vehicle is calculated based on the accessory consumption cost, the actual battery charging cost, parking costs, additional electricity costs, and service costs. The accessory consumption cost includes the electricity consumption cost of at least one component among the compressor, pressure transmitter, three-way valve, heater pump, electric fan, solenoid valve, battery water pump, and four-way valve when operating according to the thermal management control sequence. The additional electricity cost is the fixed electricity loss cost required for one charging cycle, and the service cost is the fixed service fee required for one charging cycle. The additional electricity cost is the fixed electricity loss cost per unit time; for example, if the electricity loss cost is 2 yuan per hour, then for 2 hours of charging, the electricity loss cost would be 2 * 3 = 6 yuan. The service cost is a fixed value. The service fee is 3 yuan for each charge, regardless of the charging time.

[0076] The method for obtaining the actual charging control sequence for the actual charging control of vehicle 10a can be found in the descriptions of the foregoing embodiments, and will not be repeated here.

[0077] In addition to the vehicle charging system 10 provided above, some embodiments of this application also provide a method for determining charging demand information, a vehicle charging control method, and a method for determining vehicle charging cost. The method for determining charging demand information, the vehicle charging control method, and the method for determining vehicle charging cost provided in this application can be applied to the vehicle charging system 10 described above, but are not limited to the vehicle charging system 10 provided in the above embodiments.

[0078] From the vehicle's perspective, Figure 3a This is a flowchart illustrating a method for determining charging demand information, provided as an exemplary embodiment of this application. Figure 3a As shown, the method includes:

[0079] S311: Display an interface including at least two information input elements for inputting first charging demand information and second charging demand information for charging the vehicle, wherein the first charging demand information and the second charging demand information are any two of the following charging demand information: target charging capacity, estimated charging time, and estimated charging cost.

[0080] S312: In response to an operation that inputs first charging demand information and second charging demand information from at least two information input elements, obtain third charging demand information for charging the vehicle, wherein the third charging demand information is the remaining charging demand information excluding the first demand information and second demand information from the target charging capacity, estimated charging time and estimated charging cost.

[0081] In this embodiment, an electronic display screen is installed on the vehicle. This application does not limit the type of electronic display screen; for example, it could be a central control screen or a head-up display. The electronic display screen can display user charging needs, vehicle status, and vehicle charging information. In this embodiment, the vehicle is an electric vehicle, but a hybrid electric vehicle is also possible.

[0082] In this embodiment, the user inputs first and second charging demand information via the vehicle's electronic display screen. The vehicle then sends this information to the server. Based on the first and second charging demand information, the server determines a control sequence for actual charging control of the vehicle and calculates the current actual charging cost in real time during the charging process. The first and second charging demand information can be any two of the following: target charging capacity, estimated charging time, and estimated charging cost.

[0083] In this embodiment, the vehicle's electronic display screen shows an interface including at least two information input elements for inputting first charging demand information and second charging demand information for charging the vehicle. The first charging demand information and the second charging demand information are any two of the target charging capacity, estimated charging time, and estimated charging cost. In response to the operation of inputting the first charging demand information and the second charging demand information in the at least two information input elements, a third charging demand information for charging the vehicle is obtained. The third charging demand information is the remaining charging demand information excluding the first and second demand information from the target charging capacity, estimated charging time, and estimated charging cost.

[0084] In the above embodiments of this application, there are two information input elements; the vehicle responds to the operation of inputting first charging demand information and second charging demand information in at least two information input elements to obtain third charging demand information for charging the vehicle, including: responding to the input operation of one of the two information input elements to obtain the first charging demand information; responding to the input operation of the other of the two information input elements to obtain the second charging demand information; and determining the third charging demand information for charging the vehicle based on the first charging demand information and the second charging demand information.

[0085] In one feasible approach, the information input element includes a target charging capacity slider and a time cost associated slider. The vehicle responds to a drag operation on the target charging capacity slider to obtain the target charging capacity; responds to a drag operation on the time cost associated slider to obtain the estimated charging time; and determines the estimated charging cost for charging the vehicle based on the target charging capacity and the estimated charging time.

[0086] Furthermore, the information input elements include a target charging capacity slider and a time cost associated slider, which can be arranged vertically or vertically.

[0087] In the above embodiments of this application, the information input elements can also be three, including a target charging capacity slider, a time slider, and a cost slider. One possible implementation is to obtain two charging demand information corresponding to any two sliders in response to a sliding operation on any two of the target charging capacity slider, time slider, and cost slider. For example, in response to a sliding operation on the target charging capacity slider and the time slider, the target charging capacity and the estimated charging time can be obtained; another example is to obtain the estimated charging time and the estimated charging cost in response to a sliding operation on the time slider and the cost slider; yet another example is to obtain the target charging capacity and the estimated charging cost in response to a sliding operation on the target charging capacity slider and the cost slider.

[0088] Accordingly, after acquiring the third charging demand information for charging the vehicle, the position of the slider on the slider bar corresponding to the third charging demand is automatically adjusted to the position corresponding to the third charging demand. For example, the slider position on the target charging amount is automatically adjusted to the position corresponding to the target charging amount.

[0089] Furthermore, the target charging level slider, time slider, and cost slider can be arranged in any of the following ways: side by side or in a ring.

[0090] In the above embodiments of this application, the information input elements can also be three, including a target charging capacity input item, a time input item, and a cost input item. One possible implementation is to obtain two charging demand information items corresponding to any two input items in response to information input operations on the target charging capacity input item, time input item, and cost input item. For example, in response to operations on inputting capacity and time into the target charging capacity input item and time input item, the target charging capacity and estimated charging time are obtained; as another example, in response to operations on inputting time and cost into the time input item and cost input item, the estimated charging time and estimated charging cost are obtained; as yet another example, in response to operations on inputting capacity and cost into the target charging capacity input item and cost input item, the target charging capacity and estimated charging cost are obtained.

[0091] Accordingly, after obtaining the third charging demand information for charging the vehicle, the third charging demand information is displayed in the corresponding information input field. For example, the target charging capacity is automatically displayed in the target charging capacity input field.

[0092] After obtaining third-party charging demand information, the vehicle displays this information on an electronic screen. Users can view this information to decide whether to charge the vehicle. If charging is required, the vehicle responds to the user's charging request and executes the charging operation.

[0093] It should be noted that the specific implementation of the charging capacity slider and the charging cost vs. charging time slider in this application embodiment is not limited. The charging capacity slider can be a slider for adjusting the vehicle's charging percentage or a slider for adjusting the vehicle's charging capacity; the leftmost position of the charging cost vs. charging time slider can be the position corresponding to the lowest charging cost and longest charging time, and the rightmost position of the charging cost vs. charging time slider can be the position corresponding to the highest charging cost and shortest charging time; conversely, the leftmost position of the charging cost vs. charging time slider can be the position corresponding to the highest charging cost and shortest charging time, and the rightmost position of the charging cost vs. charging time slider can be the position corresponding to the lowest charging cost and longest charging time.

[0094] From the server's perspective, Figure 3b This is a flowchart illustrating another method for determining charging demand information provided as an exemplary embodiment of this application. After taking any two of the following demand information—target charging capacity, estimated charging cost, and estimated charging time—as the first charging demand and the second charging demand, as... Figure 3b As shown, the method includes:

[0095] S321: Obtain first charging demand information and second charging demand information for charging the vehicle, wherein the first charging demand information and the second charging demand information are any two of the target charging capacity, estimated charging time and estimated charging cost.

[0096] S322: Based on the first charging demand information and the second charging demand information, determine the third charging demand information for charging the vehicle, wherein the third charging demand information is the remaining charging demand information excluding the first demand information and the second demand information from the target charging capacity, the estimated charging time, and the estimated charging cost.

[0097] In this embodiment, the server is used to determine the control sequence for actual charging control of the vehicle based on the first charging demand information and the second charging demand information. In this embodiment, the implementation form of the server is not limited; for example, the server can be a conventional server, a cloud server, a cloud host, a virtual data center, or other server equipment. The server's components mainly include a processor, hard disk, memory, system bus, and other common computer architecture types.

[0098] In this embodiment, after obtaining the first charging demand information and the second charging demand information, the vehicle sends the first charging demand information and the second charging demand information to the server. The server obtains the first charging demand information and the second charging demand information for charging the vehicle, wherein the first charging demand information and the second charging demand information are any two of the target charging capacity, the estimated charging time, and the estimated charging cost. Based on the first charging demand information and the second charging demand information, a third charging demand information for charging the vehicle is determined, wherein the third charging demand information is the remaining charging demand information other than the first demand information and the second demand information among the target charging capacity, the estimated charging time, and the estimated charging cost.

[0099] In one optional embodiment, the first demand information is the target charging capacity, the second charging demand information is the estimated charging time, and the third charging demand information is the estimated charging cost. The server then determines the third charging demand information for charging the vehicle based on the first and second charging demand information. One possible implementation involves calculating a charging current sequence for charging the vehicle based on the target charging capacity, estimated charging time, and charging pile power. This charging current sequence is a sequence of control signals sent to the battery during vehicle charging. Based on the charging current sequence, a thermal management control sequence for charging the vehicle is calculated. This thermal management control sequence is a sequence of control signals sent to components related to regulating battery coolant temperature during vehicle charging. The battery charging cost is calculated based on the charging current sequence. The accessory consumption cost is calculated based on the thermal management control sequence. The estimated charging cost for charging the vehicle is calculated based on the battery charging cost and the accessory consumption cost. The accessory consumption cost includes the consumption cost of at least one component among the compressor, pressure transmitter, three-way valve, heater pump, electric fan, solenoid valve, battery water pump, and four-way valve.

[0100] In the above embodiments, the estimated charging cost of charging the vehicle is calculated based on the battery charging cost and accessory consumption cost. One possible approach is to calculate the estimated charging cost of charging the vehicle based on the battery charging cost, accessory consumption cost, parking cost, additional electricity cost, and service cost. The additional electricity cost is the fixed electricity loss cost required for one charging cycle, and the service cost is the fixed service fee required for one charging cycle. The additional electricity cost is the fixed electricity loss cost per unit time. For example, if the electricity loss cost is 2 yuan per hour, then for 2 hours of charging, the electricity loss cost is 2 * 3 = 6 yuan. The service cost is a fixed value; for one charging cycle, the service fee is fixed at 3 yuan and is independent of the charging time.

[0101] In another optional embodiment, the first demand information is the target charging capacity, the second charging demand information is the estimated charging cost, and the third charging demand information is the estimated charging time. The server then determines the third charging demand information for charging the vehicle based on the first and second charging demand information. One possible approach is to calculate the first charging time for charging the vehicle based on the estimated charging cost and the target charging capacity; and to determine the estimated charging time for charging the vehicle based on the first charging time, the target charging capacity, and the power of the charging pile.

[0102] In the above embodiments, the server determines the estimated charging time for the vehicle based on the first charging time, the target charging capacity, and the power of the charging pile. One possible approach is to calculate the first charging cost for the vehicle based on the first charging time, the target charging capacity, and the power of the charging pile; and determine the estimated charging time for the vehicle based on the relationship between the difference between the first charging cost and the estimated charging cost and a set threshold. If the difference is less than the set threshold, the first charging time is used as the estimated charging time; if the difference is greater than or equal to the set threshold, the process is repeated to predict the charging cost for the vehicle using the estimated charging time, the target charging capacity, and the power of the charging pile, until the difference between the second charging cost and the estimated charging cost is less than the set threshold, at which point the charging time corresponding to the second charging cost is used as the estimated charging time.

[0103] In the above embodiments, the first charging cost of charging the vehicle is calculated based on the first charging time, the target charging capacity, and the power of the charging pile. One possible implementation is to calculate the charging current sequence for charging the vehicle based on the target charging capacity, the first charging time, and the power of the charging pile, wherein the charging current sequence is a sequence of control signals sent to the battery during vehicle charging; and to calculate the thermal management control sequence for charging the vehicle based on the charging current sequence, wherein the thermal management control sequence is a sequence of control signals sent to components related to regulating the battery coolant temperature during vehicle charging; to calculate the battery charging cost based on the charging current sequence; and to calculate the accessory consumption cost based on the thermal management control sequence; and to calculate the first charging cost of charging the vehicle based on the battery charging cost and the accessory consumption cost; wherein the accessory consumption cost includes the consumption cost of at least one component among the compressor, pressure transmitter, three-way valve, heater pump, electric fan, solenoid valve, battery water pump, and four-way valve.

[0104] In the above embodiments, after calculating the estimated charging time or estimated charging cost, the server sends the estimated charging time or estimated charging cost to the vehicle so that it can be displayed on the vehicle's electronic display screen. The user then decides whether to proceed with charging based on the estimated charging time or estimated charging cost.

[0105] Figure 4 A vehicle charging process control method provided in this disclosure specifically includes the following steps S401 to S403:

[0106] S401. Obtain the ratio between the expected charging cost and the expected charging time, as well as the target charging capacity.

[0107] S402. Determine the expected charging cost and expected charging time based on the target charging capacity and the ratio between the expected charging cost and the expected charging time.

[0108] S403. Based on the target charging capacity, the expected charging cost, and the expected charging time, determine the actual control sequence for actual charging control of the vehicle.

[0109] In the above embodiment, before executing S401, the method further includes: obtaining the charging capacity ratio of the vehicle; and determining the target charging capacity based on the charging capacity ratio and the remaining capacity.

[0110] In this embodiment, after obtaining the charging capacity ratio set by the user on the display screen, as well as the ratio between the estimated charging cost and the estimated charging time, vehicle 10a obtains the remaining battery power of vehicle 10a, and then determines the target charging capacity based on the remaining battery power and the charging capacity ratio. The target charging capacity is the amount of electricity required to charge the vehicle from its current remaining battery power to the set charging capacity ratio. For example, if the vehicle's current remaining battery power is 20%, the charging capacity ratio is 90%, and the target charging capacity is 70%, the target charging capacity is the amount of electricity required to charge the battery from 20% to 90%. The ratio between the estimated charging cost and the estimated charging time can be determined by the user sliding on the display screen, yielding a percentage of charging time and charging cost. Figure 2 As shown in the slider of the charging cost and charging time slider, it can be seen that if you want to charge the battery to the target charging capacity, the charging cost is relatively low and the charging time is relatively long. The charging time and charging cost are inversely proportional, that is, the longer the charging time, the lower the charging cost may be, and vice versa.

[0111] In the above embodiments, determining the estimated charging cost and estimated charging time includes: determining a minimum estimated charging cost based on the vehicle's environmental data and the target charging capacity; determining the estimated charging cost based on the minimum estimated charging cost and the ratio between the estimated charging cost and the estimated charging time; and determining the estimated charging time based on the estimated charging cost and the target charging capacity. And / or, determining a minimum estimated charging time based on the vehicle's environmental data and the target charging capacity; determining the estimated charging time based on the minimum estimated charging time and the ratio between the estimated charging cost and the estimated charging time; and determining the estimated charging cost based on the estimated charging time and the target charging capacity. Understandably, vehicle environmental data includes humidity, temperature, etc., and driving conditions include driving time, mileage, charging habits, etc. First, based on the current environmental data and the target charging capacity, determine the minimum estimated charging cost and / or the minimum estimated charging time. After determining the minimum, the estimated charging cost and estimated charging time can be calculated in two ways to ensure the ratio between the preset charging cost and the preset charging time, and their accuracy. The first method: Based on the minimum estimated charging cost and the ratio between the estimated charging cost and the estimated charging time, determine the estimated charging cost. For example, if the determined minimum estimated charging cost is 100, this minimum can be obtained without considering charging time, or it can be understood as completing charging at the lowest cost. If the ratio is 20%, the product of the minimum estimated charging cost of 100 and the ratio of 20% can be calculated, and then added to the minimum estimated charging cost of 100 to determine the estimated charging cost as 120. Then, based on the estimated charging time... The first method involves determining the estimated charging time based on cost and target charging capacity. Refer to the method described above for calculating estimated charging time based on estimated charging cost; this will not be repeated here. This method ensures a proportional relationship between estimated charging cost and estimated charging time, increasing their correlation and making the calculation more accurate. The second method determines the estimated charging time based on the minimum estimated charging time and the proportional relationship between estimated charging cost and estimated charging time. The minimum estimated charging time can be the minimum charging time obtained without considering charging cost; it can be understood as the shortest charging time and the maximum charging cost. The minimum estimated charging time could be 50 minutes. If the proportional relationship is 20%, the product of the proportional relationship and the minimum estimated charging time of 50 minutes can be calculated, and then added to the minimum estimated charging time of 50 minutes to determine the estimated charging time as 60 minutes. Finally, the estimated charging cost is determined based on the estimated charging time and target charging capacity. Refer to the method described above for calculating estimated charging cost based on estimated charging time; this will not be repeated here.

[0112] In the above embodiments, any two of the following demand information—target charging capacity, expected charging cost, and expected charging time—are used as the first charging demand and the second charging demand.

[0113] After determining the first charging demand information and the second charging demand information, the server determines the actual control sequence for actual charging control of the vehicle based on the first charging demand information and the second charging demand information. The actual control sequence is a sequence of control signals sent to the charging-related components of the vehicle during charging.

[0114] In the above embodiments, the server simulates the charging process of the vehicle based on the first charging demand information and the second charging demand information to obtain the actual control sequence for actual charging control of the vehicle. One possible approach is to obtain a simulation control sequence for simulating charging control of the vehicle based on the first charging demand information and the second charging demand information; and to determine the actual control sequence for actual charging control of the vehicle based on the simulation results of the charging process of the vehicle using the simulation control sequence.

[0115] Specifically, based on the first and second charging demand information, the vehicle's control sequence is optimized. The vehicle's control sequence refers to the sequence of control signals currently sent by the vehicle to the battery, resulting in a simulated control sequence for simulating vehicle charging. One possible approach is to utilize a multi-objective control algorithm, using the first and second charging demand information as objectives, to obtain the simulated control sequence for simulating vehicle charging.

[0116] Specifically, based on the simulation results of the vehicle's charging process using the simulated control sequence, an actual control sequence for actual vehicle charging control is determined. One possible approach is to simulate the vehicle's charging process using the simulated control sequence to obtain first simulated charging information, which is simulated information corresponding to the target charging capacity, estimated charging time, and estimated charging cost. First charging demand information and second charging demand information are matched with the corresponding simulated information in the first simulated charging information to generate a judgment result. Based on the judgment result, the actual control sequence for actual vehicle charging control is determined. It should be noted that the first simulated charging information includes the simulated charging time, simulated charging cost, and simulated charging capacity corresponding to the estimated charging time, estimated charging cost, and target charging capacity, respectively. To determine whether the first simulated charging information matches the first charging demand information and the second charging demand information, when the first and second charging demand information are the expected charging time and the target charging capacity, the difference between the expected charging time and the simulated charging time can be used to determine whether the first simulated charging information matches the first charging demand information and the second charging demand information. If the difference between the expected charging time and the simulated charging time is less than the first threshold and the difference between the target charging capacity and the simulated charging capacity is less than the second threshold, then the first simulated charging information matches the first charging demand information and the second charging demand information; otherwise, the first simulated charging information does not match the first charging demand information and the second charging demand information. When the first and second charging demand information are the expected charging cost and the target charging capacity, and when the first and second charging demand information are the expected charging cost and the expected charging time, the same method can be used to determine whether the first simulated charging information matches the first charging demand information and the second charging demand information.

[0117] In the above embodiments, if the determination result is a match, the simulated control sequence is used as the actual control sequence for actual charging control of the vehicle. At this time, the third charging demand information determined in the first simulated charging information can be displayed before charging, after the user inputs the first and second charging demand information, or it can be displayed during the charging process.

[0118] In the above embodiments, if the judgment result is a mismatch, the calculation simulation control sequence is updated until the target simulation charging information matches the first charging demand information and the second charging demand information, and the target simulation control sequence corresponding to the target simulation charging information is used as the actual control sequence for actual charging control of the vehicle.

[0119] In another feasible approach, a simulated control sequence is input into a charging demand prediction model to obtain first simulated charging information. The training steps for the charging demand prediction model are as follows: collect control sequence samples and charging demand information samples; train the model based on the control sequence samples and charging demand information samples to obtain the charging demand prediction model.

[0120] In the above embodiments, after determining the actual control sequence, the actual control sequence can be sent to vehicle charging-related components so that the vehicle can perform charging control according to the actual control sequence. After the actual control sequence is sent to the vehicle, during the actual charging control process, the vehicle returns actual charging information to the server. The server uses the actual charging information to further optimize the control sequence to obtain a new control sequence. One possible approach is to receive the actual charging information returned by the vehicle; optimize the vehicle's control sequence based on the actual charging information to obtain a third simulated control sequence for charging the vehicle; simulate the vehicle's charging process using the third simulated control sequence to obtain a new control sequence for actual charging control of the vehicle; and send the new control sequence to the vehicle so that the vehicle can perform charging control according to the new control sequence. Understandably, after the generated actual control sequence is sent to the vehicle, the vehicle controls the battery to charge according to the actual control sequence and returns the actual charging status of the vehicle to the server. The server then re-simulates based on the actual charging status, generates a new control sequence, and sends the new control sequence to the vehicle. This is a process of adjusting the charging sequence in real time according to the actual charging status of the vehicle, which can charge the vehicle battery more rationally, reduce the waste of charging resources, further reduce charging time and charging costs, and make the method more flexible.

[0121] Figure 5 This is a flowchart illustrating a method for determining vehicle charging costs, provided as an exemplary embodiment of this application. Figure 5 As shown, the method includes:

[0122] S501: Obtain the thermal management control sequence and charging current sequence for actual charging control of the vehicle. The thermal management control sequence is a sequence of control signals sent to components related to adjusting the battery coolant temperature during vehicle charging, and the charging current sequence is a sequence of control signals sent to the battery during vehicle charging.

[0123] S502: Determine the actual charging cost of charging the vehicle based on the thermal management control sequence and the charging current sequence.

[0124] In this embodiment, throughout the entire vehicle charging process, the server sends control sequences for charging control to the vehicle in real time. The server obtains the thermal management control sequence and charging current sequence for the actual charging control of the vehicle; based on the thermal management control sequence and charging current sequence, the server determines the actual charging cost of charging the vehicle. The server calculates the actual charging cost at any point in the charging process in real time.

[0125] In the above embodiment, after the server determines the actual charging cost of charging the vehicle based on the thermal management control sequence and the charging current sequence, the server sends the actual charging cost to the vehicle. The vehicle displays the actual charging cost for the user to view. The actual charging cost can be the charging cost at any time during the charging process.

[0126] In the above embodiments, the server determines the actual charging cost of charging the vehicle based on the thermal management control sequence and the charging current sequence. One possible implementation is that the server obtains the accessory consumption cost based on the thermal management control sequence; the server obtains the actual battery charging cost based on the charging current sequence; and the server determines the actual charging cost of charging the vehicle based on the accessory consumption cost and the actual battery charging cost. For example, the server obtains the consumption cost of each component based on the thermal management control sequence to obtain the total accessory consumption cost; the server calculates the actual battery charging cost based on the charging current sequence and the charging time sequence corresponding to each charging current sequence.

[0127] In the above embodiments, the server determines the actual charging cost of the vehicle based on the cost of accessories consumed and the actual charging cost of the battery. One possible approach is for the server to calculate the actual charging cost of the vehicle based on the cost of accessories consumed, the actual charging cost of the battery, parking costs, additional electricity costs, and service costs. For example, parking costs can be calculated using the parking unit price and parking duration; a pre-set service fee and additional electricity fee are required for each charging cycle of the vehicle, which are considered as service costs and additional electricity costs.

[0128] It should be noted that the cost of accessories includes the cost of at least one of the following components when operating according to the thermal management control sequence: compressor, pressure transmitter, three-way valve, heater pump, electric fan, solenoid valve, battery pump, and battery four-way valve.

[0129] In the above system embodiments of this application, the first position of the first slider on the charging power slider and the second position of the second slider on the charging cost versus charging time slider are obtained. Based on the first and second positions, the estimated charging time and estimated charging cost for the vehicle are predicted. Users can set the target charging power, estimated charging time, and estimated charging cost by dragging the positions of the sliders on the charging power slider and the charging cost versus charging time slider. Users can balance the charging time and charging cost for the vehicle, thus improving the user experience.

[0130] During the actual charging process of the vehicle, the server determines the actual charging cost based on the acquired actual charging control sequence. This actual charging cost can be sent from the server to the vehicle for real-time display during the user's charging process.

[0131] The actual charging sequence includes a thermal management control sequence and a charging current sequence. The actual charging cost of the vehicle is determined based on these sequences. One possible approach is to obtain the accessory consumption cost based on the thermal management control sequence; obtain the actual battery charging cost based on the charging current sequence; and determine the actual charging cost of the vehicle based on both the accessory consumption cost and the actual battery charging cost. Optionally, the actual charging cost of the vehicle is calculated based on the accessory consumption cost, the actual battery charging cost, parking costs, additional electricity costs, and service costs. The accessory consumption cost includes the electricity consumption cost of at least one component among the compressor, pressure transmitter, three-way valve, heater pump, electric fan, solenoid valve, battery water pump, and four-way valve when operating according to the thermal management control sequence. The additional electricity cost is the fixed electricity loss cost required for one charging cycle, and the service cost is the fixed service fee required for one charging cycle. The additional electricity cost is the fixed electricity loss cost per unit time; for example, if the electricity loss cost is 2 yuan per hour, then for 2 hours of charging, the electricity loss cost would be 2 * 3 = 6 yuan. The service cost is a fixed value. The service fee is 3 yuan for each charge, regardless of the charging time.

[0145] The determination module 92 is used to determine the actual charging cost of charging the vehicle based on the thermal management control sequence and the charging current sequence.
