[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0028] According to an embodiment of this application, a method embodiment for charging control of a vehicle is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0029] This embodiment provides a method for controlling the charging of a vehicle. Figure 1 This is a flowchart of a vehicle charging control method according to an embodiment of this application. Figure 1 As shown, the method may include the following steps:

[0030] Step S102: Obtain the electricity price period information of the charging pile and the vehicle demand information. The charging pile is used to charge the vehicle, the electricity price period information is used to represent the multiple electricity prices corresponding to the charging pile in multiple time periods, and the demand information includes at least the vehicle's charging end time.

[0031] In the technical solution provided in step S102 of this application, the aforementioned electricity price period information can be used to determine the electricity price corresponding to the charging pile in different time periods. The aforementioned demand information can be user demand information, which can be used to determine the start charging time, end charging time, and other information of the vehicle. It should be noted that this is only an example and there are no specific limitations on the content included in the demand information.

[0032] Optionally, the aforementioned requirement information may include: target State of Charge (SOC), user-set charging completion time (i.e., charging end time), charging priority, schedule, health reminders, etc. The target SOC can be different SOCs selected by the user based on different travel plans. For example, if the user plans a long trip tomorrow, they might set the target SOC to 100% to ensure the battery is fully charged; while for daily commutes, they might set the target SOC to 80% to extend battery life and reduce charging time. The charging end time can be the charging cutoff time. For example, if the user plans to leave for work at 8 am the next morning, the charging cutoff time can be set to 7 am to ensure charging is completed before peak electricity prices arrive. The charging priority can be the charging priority selected by the user, such as "cost priority," "time priority," or "balanced charging." In "cost priority" mode, charging can be done during off-peak hours as much as possible; in "time priority" mode, fast charging is prioritized even during peak hours; "balanced charging" is between time priority and cost priority modes, finding the optimal balance between cost and time.

[0033] Optionally, the aforementioned schedule can be the user-input schedule for the following day. For example, if there is an urgent meeting, charging may need to be completed in advance. The schedule will influence the formulation of the charging strategy to ensure that the vehicle reaches the required charge level before a specific time. The aforementioned personalized preferences may refer to situations where some users are sensitive to charging noise and may wish to reduce the charging current at night to avoid disturbing nearby residents. Although this may slightly increase charging costs, it meets the user's personalized needs.

[0034] Optionally, if the user sets a nighttime sleep time, the charging strategy can avoid high-intensity charging during sleep, reducing the health effects of electromagnetic radiation.

[0035] Optionally, the above demand information will be comprehensively considered by the charging strategy optimization module to formulate a charging plan that meets user expectations and is both cost-effective and efficient.

[0036] Optionally, when the vehicle needs to be charged, the vehicle can obtain the peak-valley-flat electricity price information of public charging stations through wireless communication technology. It can also obtain the vehicle's demand information, which can be the current state of charge obtained through the vehicle's controller, or a target state of charge obtained based on user-defined settings. There are no specific restrictions on the method of obtaining the demand information.

[0037] Table 1. Electricity Price Information for a Public Charging Station During Certain Time Periods

[0038]

[0039] Table 1 shows the electricity price information for a certain public charging station. As shown in Table 1, the electricity price for the charging station varies at different times. If the charging time can be controlled during off-peak hours, the electricity cost can be reduced by nearly half compared to the average usage time and by nearly two times compared to the peak usage time.

[0040] For example, the demand information could be that a typical user scenario is that after get off work, they usually park their vehicle at the public charging station at 6 PM to charge it until 7 AM the next morning before heading to work, and the user wants the lowest possible electricity price while ensuring the vehicle is fully charged.

[0041] Optionally, the aforementioned electricity price time period information can be set by the charging pile operator based on grid load and costs, and may include peak hours, flat hours, and off-peak hours, each with a different electricity price. Vehicles exchange data with the charging pile or charging pile management system via wireless communication technologies (such as 4G, 5G, Wi-Fi, Bluetooth, etc.) to obtain the latest electricity price time period information in real time.

[0042] Optionally, the aforementioned requirements information includes, but is not limited to, charging end time, target SOC, charging priority, vehicle schedule, and personalized preferences. Among these, the charging end time is the desired point in time when the user wants the vehicle to finish charging, and it directly affects the determination of the charging period. For example, if a user wants the vehicle fully charged before 7:00 AM the following morning, this will become a crucial constraint in formulating the charging strategy.

[0043] In this embodiment, not only is real-time electricity price information obtained from charging stations, but historical data and market trends can also be analyzed, combined with artificial intelligence (AI) algorithms, to predict future electricity price periods and develop more forward-looking charging plans for users. For example, it can predict that electricity prices may differ on weekends, and inform users in advance to adjust their charging strategies.

[0044] Optionally, it can also collect electricity price information from multiple charging stations simultaneously to provide users with optimal charging location recommendations. This includes not only charging stations with the lowest electricity prices, but also factors such as charging station availability and location convenience.

[0045] Optionally, by learning users' charging habits and schedules, it's possible to predict user needs and automatically recommend or adjust charging strategies when users haven't explicitly set them. For example, if it's observed that a user consistently charges at a particular charging station every Friday evening, the system can automatically obtain the electricity pricing information for that charging station on Fridays and preset a charging strategy for the user.

[0046] Optionally, the electricity price period acquisition module can obtain the "peak-valley-flat" electricity price period information of the charging pile in real time through a wireless communication technology data interface with the charging pile management system. Simultaneously, the user can obtain the electricity price period information of the public charging pile through the interactive interface module and complete the settings to obtain the user's demand information: this demand information can at least include the charging cutoff SOC (100%) and the target charging completion time (7 o'clock). In addition, this user interface module can display the calculated optimal charging strategy and the real-time charging status after charging starts, allowing users to view and adjust the charging strategy according to their actual needs.

[0047] Step S104: Based on demand information, determine the charging period of the vehicle, and based on electricity price period information and charging period, determine the charging current of the vehicle in at least one sub-charging period within the charging period.

[0048] In the technical solution provided in step S104 of this application, the charging period of the vehicle can be determined based on the demand information. Furthermore, based on the electricity price period information and the charging period, the charging period can be divided to obtain at least one sub-charging period and multiple charging currents within each sub-charging period.

[0049] Optionally, an optimal charging strategy can be automatically formulated based on electricity price information and user needs. High-current, high-power charging can be used during off-peak hours, while charging can be paused or low-current, low-power charging can be used during peak hours. The charging mode is automatically adjusted according to the charging strategy, controlling the charging current and voltage to achieve the lowest charging cost. This charging strategy can be used to determine the charging period, at least one sub-charging period, and the corresponding charging current for each sub-charging period.

[0050] Optionally, after obtaining the electricity price and time period information for the charging station and the vehicle's demand information, a total charging period can be determined to ensure that charging is completed before the time specified by the user. The determination of this charging period can take into account the vehicle's current state of charge (SOC) and the user's needs, and the time and amount of electricity required to complete charging can be calculated.

[0051] Optionally, the total charging period can be determined based on the start and end times of charging. Once the total charging period is determined, it can be divided into multiple sub-charging periods based on electricity price information, and an optimal charging current can be determined for each sub-charging period. During off-peak hours, such as at night, higher current and power are tended to be used to fully utilize the lower electricity prices; while during peak hours, such as weekday mornings, the system may suspend charging or use a lower current to avoid high electricity bills.

[0052] In this embodiment, not only is the charging current adjusted according to electricity price periods, but the charging power can also be dynamically adjusted. For example, during off-peak hours, the charging power may be dynamically increased based on the remaining battery capacity and time to complete charging faster, while the power may be appropriately reduced during peak hours to reduce electricity costs. Furthermore, the charging strategy can be adjusted based on the battery's health status and charging efficiency. When the battery's health status is poor or the charging efficiency is low, the charging current can be appropriately reduced even during off-peak electricity price periods to minimize negative impacts on the battery and extend its lifespan.

[0053] Optionally, the system can also predict future battery consumption based on vehicle driving history data and user schedules, and then adjust the charging strategy accordingly. For example, if a user plans a long trip the next day, the system can increase the charging current during off-peak hours to ensure sufficient battery reserves.

[0054] Optionally, when formulating a charging strategy, multiple objectives can be considered simultaneously, such as minimizing charging costs, shortening charging time, and protecting battery health. This requires the system to employ more complex optimization algorithms, such as genetic algorithms, particle swarm optimization, or deep reinforcement learning, to find the optimal balance between the various objectives.

[0055] Optionally, the charging strategy optimization module can calculate and formulate the optimal charging strategy based on electricity price time information and user-set requirements. This charging strategy can be used to determine the charging current corresponding to different sub-charging time periods. Provided the user requires a full charge, the module can automatically calculate the proportion of charging during off-peak hours and adjust the charging power. From 6 PM to 9 PM, the charging control module sets the charging current and power to lower values, such as 5 amps (A) and 1 kilowatt (kW); from 10 PM to 6 AM, it sets the charging current and power to higher values, such as 32A and 7kW; and from 9 PM to 10 PM and 6 AM to 7 AM, it sets the charging current and power to higher values, such as 10A and 2kW, ultimately achieving a total charging of 63 kWh.

[0056] Step S106: According to the charging current, control the vehicle to charge within at least one sub-charging period so as to complete the charging of the vehicle at the end of the charging period.

[0057] In the technical solution provided in step S106 of this application, after determining the sub-charging period and the charging current corresponding to the sub-charging period, the vehicle can be controlled to charge within at least one sub-charging period according to the charging current, so as to complete the charging of the vehicle at the end of the charging time.

[0058] Optionally, based on the electricity price period information, vehicle demand information, and the established charging strategy determined in the first two steps S102 and S104, the charging process of the vehicle is actually controlled to ensure that the vehicle completes charging at the predetermined charging end time, while optimizing costs.

[0059] Optionally, in step S106, the vehicle can be controlled to charge during each sub-charging period according to a previously determined charging current. The key here is that the charging control module must have the ability to dynamically adjust charging parameters to accurately execute the optimized charging strategy. For example, during off-peak electricity price periods, the charging control module should adjust the charging current to a higher value, such as 32A and 7kW, to fully utilize the low-priced electricity; while during peak electricity price periods, the current may be reduced to 5A and 1kW, or charging may be completely stopped to avoid high electricity costs.

[0060] Optionally, the charging control module can be used to automatically adjust and control the allowable charging current and voltage according to the charging strategy.

[0061] Optionally, the charging control module can also continuously monitor the vehicle's real-time charging status, including SOC, battery temperature, and charging rate, to ensure that the charging process proceeds according to the predetermined strategy. It can also respond promptly to any abnormal situations, such as battery overheating or grid fluctuations, to prevent charging interruption or damage to battery health.

[0062] Optionally, during charging, the user interface module can display the current charging status and strategy execution, which users can check at any time and fine-tune according to their individual needs. For example, if a user suddenly decides to depart earlier, they can temporarily modify the charging strategy through the user interface to speed up the charging process and accommodate the new travel plans.

[0063] With the increasing popularity of electric vehicles, users' charging needs and usage scenarios are becoming more diverse. Due to the limitations of fixed parking spaces for private charging pile installation, the frequency of use of public charging piles is rising. Beyond short-term charging needs, electric vehicles are increasingly being charged for extended periods, even overnight, using slow charging stations. However, the electricity price for public slow charging stations is typically differentiated based on peak, off-peak, and normal times: higher prices during peak hours, moderate prices during normal hours, and lower prices during off-peak hours.

[0064] In related technologies, electric vehicles typically employ a fixed charging strategy when charging at public charging stations, which cannot be optimized based on changes in electricity prices during different times of day, resulting in high charging costs. Public charging stations do not support scheduled charging; to achieve low-cost charging, users often need to set an alarm and go to the charging station in the middle of the night to scan a code / swipe a card to start charging. This manual operation is cumbersome and inefficient.

[0065] To achieve the lowest charging cost when charging at public charging stations, this application provides a method for optimizing charging time periods based on peak-valley-flat electricity prices. This method automatically adjusts the charging strategy, controlling the charging current and power based on the peak-valley-flat electricity price differences set by the charging station, thus minimizing charging costs. By automatically acquiring electricity price information and combining it with charging strategy optimization and control, this method effectively reduces charging costs and improves user experience. It also ensures uninterrupted charging while achieving low-cost charging, thus offsetting parking fees.

[0066] Through the above steps S102 to S106, the electricity price period information of the charging pile and the demand information of the vehicle are obtained. The charging pile is used to charge the vehicle, the electricity price period information is used to represent the multiple electricity prices corresponding to the charging pile in multiple periods, and the demand information includes at least the charging end time of the vehicle. Based on the demand information, the charging period of the vehicle is determined, and based on the electricity price period information and the charging period, the charging current of the vehicle in at least one sub-charging period of the charging period is determined. According to the charging current, the vehicle is controlled to charge in at least one sub-charging period so as to complete the charging of the vehicle at the charging end time. In other words, in this embodiment of the application, the electricity price period information of the charging pile is obtained. When the vehicle needs to be charged, the vehicle's demand information is obtained. Based on the demand information, the charging period of the vehicle can be determined. Based on the charging period and the electricity price period information, the charging current of the vehicle in at least one sub-charging period is determined. In the sub-charging period, the vehicle can be controlled to charge according to the determined charging current, so as to achieve the purpose of charging the vehicle within the charging period. According to the different electricity prices in different periods, the charging current of different sub-charging periods is determined, so that the vehicle can be charged at a lower cost, thereby achieving the technical effect of reducing the vehicle charging cost and solving the technical problem of high vehicle charging cost.

[0067] The above-mentioned method of this application will be further described below.

[0068] As an optional implementation, step S104, based on demand information, determines the charging period of the vehicle, including: obtaining the charging end time, charging start time, and target state of charge of the vehicle from the demand information; and determining the charging period for charging the vehicle based on the charging end time and charging start time.

[0069] In this embodiment, the vehicle's charging end time, charging start time, and target state of charge can be obtained from the demand information. Based on electricity price periods and user-defined demand information, an optimal charging strategy can be calculated and formulated. Provided the user requests a full charge of the vehicle's battery, the system automatically calculates the proportion of charging during off-peak hours and adjusts the charging power accordingly.

[0070] Optionally, the charging period for the vehicle can be determined based on the charging end time and the charging start time.

[0071] Optionally, after obtaining the demand information, the charging end time and charging start time can be determined based on the demand information. Based on the charging end time and charging start time, the charging period for charging the vehicle can be determined. This charging period can be the difference between the charging end time and the charging start time. However, the charging time can also be adjusted according to the user's preference data set in the demand information. For example, if the user's preference data is to minimize the charging cost, then charging during high-price periods can be reduced, and the charging current during low-price periods can be increased.

[0072] Optionally, after obtaining the charging end time and the charging start time, in addition to determining the difference between the charging end time and the charging start time as the charging period, a certain time period between the charging end time and the charging start time can also be determined as the charging period. It should be noted that this is only an example and there are no specific restrictions on the method of determining the charging period.

[0073] As an optional implementation, based on electricity price period information and charging period, the charging current of the vehicle in at least one sub-charging period within the charging period is determined, including: determining the difference between the vehicle's current state of charge and the target state of charge; using electricity price period information, the charging period is divided into at least one sub-charging period; and based on the difference, electricity price period information, and the number of at least one sub-charging period, the charging current within the sub-charging period is determined.

[0074] In this embodiment, the current state of charge (SOC) of the battery in the vehicle is determined. Further, the difference between the current SOC and the target SOC can be determined. Based on this difference and electricity price period information, the charging period is divided into at least one sub-charging period. And based on this difference and the electricity price period information, the charging current within each sub-charging period is determined.

[0075] Optionally, the difference between the current state of charge (SOC) and the target SOC can be determined. Based on this difference, the amount of electricity the vehicle needs to replenish to reach the user-specified target SOC can be quantified. For example, assuming the vehicle's current CSOC is 20%, and the user wants to reach 100% TSOC before departure the next morning, the required replenishment amount is 80% of the SOC (i.e., the increment from 20% SOC to 100% SOC). Furthermore, based on the obtained peak-valley-flat electricity price information for charging stations, the total charging period can be subdivided into multiple sub-charging periods. Each sub-charging period corresponds to a specific electricity price, such as peak hours, flat hours, and off-peak hours. The purpose of this subdivision is to adopt different charging strategies during different electricity price periods, thereby maximizing economic benefits. For example, if a user wants to finish charging before 7:00 AM the next morning, the electricity price period can be analyzed, and the total charging period from 6:00 PM to 7:00 AM can be divided into three parts: 6:00 PM to 9:00 PM: peak period (electricity price approximately 1 yuan / kWh), 9:00 PM to 10:00 PM: flat period (electricity price approximately 0.65 yuan / kWh), and 10:00 PM to 7:00 AM: off-peak period (electricity price approximately 0.36 yuan / kWh).

[0076] After determining the required charge difference and the sub-charging periods, the optimal charging current for each sub-charging period can be calculated based on the charge demand, electricity prices during each period, and the characteristics of the vehicle's battery. This calculation process needs to comprehensively consider charging efficiency, battery capacity, charging rate limitations, and electricity price factors.

[0077] For example, assuming a vehicle battery capacity of 60 kWh, a current state of charge (SOC) of 20%, and a target SOC of 100%, requires 48 kWh of charge to be replenished during charging. To achieve economical charging of this 48 kWh, the system will allocate the charging current as follows: During peak hours from 6:00 PM to 9:00 PM, to avoid high electricity costs, the charging current may be set to a lower value, such as 5A and 1kW, for slow charging. During the off-peak hours from 9:00 PM to 10:00 PM, although electricity prices are slightly higher, the system may maintain a lower current or gradually increase the current to prepare for efficient charging during off-peak hours due to the shorter timeframe. During off-peak hours from 10:00 PM to 7:00 AM, due to low electricity prices, the system can increase the charging current to a higher value, such as 32A and 7kW, to quickly replenish most of the charge. During the final period from 6:00 to 7:00, in order to ensure that charging is completed before the target time and to avoid overcharging, the system adjusts the charging current to a moderate value, such as 10A and 2kW, to complete the final charging task.

[0078] This refined charging current regulation strategy not only maximizes cost savings but also ensures charging is completed within the user's preset time, while also taking into account battery health maintenance, demonstrating the flexibility and intelligence of the charging control strategy.

[0079] Optionally, the difference between the current state of charge and the target state of charge can be determined. Based on the difference and the electricity price period information, the charging period can be divided into at least one sub-charging period. Based on the difference and the number of sub-charging periods, the corresponding charging current in the sub-charging period can be determined.

[0080] Optionally, the demand information and electricity price period information are transmitted to the charging strategy optimization module, which can determine at least one sub-charging period and the corresponding charging current for that sub-charging period.

[0081] As an optional implementation, the charging current within a sub-charging period is determined based on the difference, electricity price period information, and the number of at least one sub-charging period, including: determining the required charging power within the sub-charging period based on the difference, electricity price period information, and the number of at least one sub-charging period; and converting the charging power using the nominal voltage of the battery in the vehicle to obtain the charging current of the vehicle within the sub-charging period.

[0082] In this embodiment, the required charging power within a sub-charging period can be determined first based on the difference in electricity price, time period information, and the number of at least one sub-charging period. The charging power can then be converted using the nominal voltage of the vehicle's battery to obtain the charging current of the vehicle within the sub-charging period. The nominal voltage can be the battery voltage of the vehicle's battery.

[0083] Optionally, based on electricity price time information, the power corresponding to each time period is determined, and based on the power, the charging current corresponding to each time period is determined.

[0084] Optionally, the aforementioned battery voltage can be a variable value, which can vary depending on various factors such as the battery's state of charge / discharge, temperature, aging, and chemical characteristics. Specifically, the battery voltage will differ at different SOC levels; generally, the voltage is higher when the battery is near full charge and decreases when the charge is low. Temperature also affects battery voltage. At lower temperatures, the battery's internal resistance increases, leading to a slight decrease in voltage; while as the temperature rises, the battery voltage may increase slightly, but excessively high temperatures can cause a decline in battery performance and potentially unstable voltage. Furthermore, as the battery is used over time, it gradually ages, and its internal structure and chemical reaction efficiency decrease, resulting in a drop in both open-circuit voltage and discharge voltage.

[0085] Optionally, different types of batteries (such as lithium-ion batteries, nickel-metal hydride batteries, lead-acid batteries, etc.) have different voltage characteristics. The nominal voltage of lithium-ion batteries is 3.6 volts (V) or 3.7V, but their voltage range may vary from 2.5V to 4.2V, while the nominal voltage of nickel-metal hydride batteries is 1.2V.

[0086] Therefore, the charging strategy module can determine the required charging power within a sub-charging period based on the difference in electricity price, time period information, and the number of at least one sub-charging period. After determining the charging power, the nominal voltage of the battery in different sub-charging periods can be determined based on information such as the type and state of the battery in the vehicle. This nominal voltage can then be used to convert the charging power to obtain the charging current of the vehicle in each sub-charging period.

[0087] Optionally, in electric vehicle charging control, the adjustment of charging current and voltage is based on the battery's current voltage and state of charge (SOC). To achieve efficient charging, the charging system dynamically adjusts the charging current and voltage to match the battery's voltage characteristics, while avoiding overcharging or over-discharging, ensuring battery safety and extending battery life. Therefore, the charging strategy needs to take into account changes in battery voltage to achieve optimal charging performance.

[0088] As an optional implementation, step S104, obtaining the vehicle's demand information, includes: responding to a selection command executed on the display interface of the vehicle's infotainment system, and determining the demand information indicated by the selection command, wherein the selection command is at least used to set the vehicle's charging end time and the vehicle's target state of charge.

[0089] In this embodiment, users can set the target SOC or target charging cutoff time (i.e., the charging end time) through the interface, and view and adjust the charging strategy.

[0090] Optionally, the user can input a selection command through the vehicle's infotainment system, which can be used to set demand information. Therefore, in response to the selection command, the vehicle can determine the demand information indicated by the selection command to determine the user-set charging end time and the vehicle's target state of charge.

[0091] Optionally, when a user operates the vehicle's infotainment interface, the vehicle can respond to the user's selected commands. These commands can include touchscreen taps, swipes, or voice commands, and can be used to set vehicle charging parameters, such as charging completion time and target SOC. It should be noted that the settings described here are for illustrative purposes only and are not intended to impose specific limitations.

[0092] Optionally, in response to receiving a selection command, the user's selection command can be parsed to determine the user's charging needs, thereby obtaining information such as the charging end time and the target state of charge.

[0093] Optionally, parsing the selection command can reveal the user's specific expectations for the charging process, including when charging will be completed and what state of charge will be reached.

[0094] For example, suppose a user sets the following requirements on the electric vehicle's infotainment system: charging end time, 5 AM the next day; target state of charge, 100% SOC. The user can set these via a specific menu on the touchscreen, allowing them to select or input the specific charging end time and target SOC percentage. Upon receiving the user's selection, this information can be used as input for subsequent calculations and strategy development. For instance, after determining the charging end time and target SOC, the system will combine the vehicle's current state of charge to calculate the required charging capacity and time under different electricity price periods, and then formulate a charging strategy, including control over charging current and power.

[0095] Through the aforementioned interactive methods, users can easily set their personal charging needs, and the vehicle can then provide customized charging services based on these needs and external electricity price information, ensuring that the vehicle's charging needs are met while also being the most economical. This is the first step in realizing intelligent charging control and the cornerstone for ensuring the effective execution of the entire charging optimization solution.

[0096] It should be noted that, in addition to using the vehicle's infotainment system to input selection commands, selection commands can also be input via mobile terminals. There are no specific restrictions on the method of inputting selection commands here.

[0097] As an optional implementation, after determining the charging current of the vehicle in at least one sub-charging period during the charging period, the method further includes: displaying the sub-charging period and the charging current in the sub-charging period on a display interface; determining the adjusted charging end time and the adjusted target state of charge in response to an adjustment command executed on the display interface; and redetermining the charging period of the vehicle and the charging current of the vehicle in at least one sub-charging period during the charging period based on the adjusted charging end time and the adjusted target state of charge.

[0098] In this embodiment, after determining the sub-charging period and the corresponding charging current based on the selection command, an adjustment command can also be input on the display interface. The vehicle responds to the adjustment command by determining the adjusted charging end time and the adjusted target state of charge. Based on the adjusted charging end time and the adjusted target state of charge, the vehicle's charging period and the charging current within at least one sub-charging period of the charging period can be redefined.

[0099] Optionally, the display interface can show electricity price information, charging strategies, and charging status. Users can set the target SOC or target charging deadline through the interface, and view and adjust the charging strategy.

[0100] Optionally, once the system calculates a charging strategy based on current demand, including the charging current for different sub-charging periods, this information can be displayed intuitively on the vehicle's screen. Users can directly see the start and end times of charging for each sub-period, the charging current magnitude, and the expected charging progress or cost. If users wish to make adjustments after viewing the charging strategy, such as changing the charging end time or target SOC, they can execute the corresponding adjustment commands on the vehicle's screen. These commands may include modifying the percentage of the target SOC, setting an earlier or later charging end time, etc.

[0101] Furthermore, it can capture user adjustment commands and determine the adjusted charging end time and target state of charge based on the new command information. For example, a user may need to complete charging before 4 a.m. instead of 5 a.m. due to a sudden change in travel arrangements; or, considering the driving distance the next day, decide to lower the target SOC from 100% to 80% to reduce charging costs and time.

[0102] Optionally, upon receiving a new user request, the charging strategy can be recalculated using the latest charging end time and target state of charge. This may include re-splitting the charging period into sub-charging periods and determining the charging current within each sub-charging period based on electricity price information and the user's new preferences for charging speed and cost.

[0103] For example, if a user sets their target end time for charging to 4 AM, they can correspondingly reduce charging time during off-peak hours, possibly by increasing charging current during peak and off-peak hours to compensate and ensure charging is completed within the new target time. If a user reduces their target SOC to 80%, they can appropriately reduce charging current during off-peak hours or extend charging intervals based on lower power demand, further reducing charging costs.

[0104] Through the steps described above, the system not only provides initial charging strategy planning but also dynamically adjusts based on changes in the user's real-time needs, making the entire charging process more user-friendly and efficient. This real-time feedback and adjustment mechanism enhances the user experience and demonstrates the flexibility and intelligence of the charging control system.

[0105] In this embodiment, the electricity price period information of the charging pile is obtained. When the vehicle needs to be charged, the vehicle's demand information is obtained. Based on the demand information, the charging period of the vehicle can be determined. Based on the charging period and the electricity price period information, the charging current of the vehicle in at least one sub-charging period is determined. In the sub-charging period, the vehicle can be controlled to charge according to the determined charging current, so as to achieve the purpose of charging the vehicle within the charging period. According to the different electricity prices in different periods, the charging current of different sub-charging periods is determined, so that the vehicle can be charged at a lower cost, thereby achieving the technical effect of reducing the vehicle charging cost and solving the technical problem of high vehicle charging cost.

[0106] In this application embodiment, a vehicle charging control system is also provided. Figure 2 This is a flowchart of a vehicle charging control system according to an embodiment of this application. Figure 2 As shown, the system may include: an electricity price period acquisition module 202, a vehicle-mounted system 204, a charging current determination module 206, and a charging control module 208.

[0107] The electricity price period acquisition module 202 is used to acquire the electricity price period information of the charging pile and the demand information of the vehicle. The charging pile is used to charge the vehicle, and the electricity price period information is used to represent the multiple electricity prices corresponding to the charging pile in multiple time periods.

[0108] The vehicle infotainment system 204 is used to execute selection commands on the display interface of the vehicle infotainment system and determine the demand information indicated by the selection command, wherein the demand information includes at least the charging end time of the vehicle.

[0109] The charging current determination module 206 is used to determine the charging period of the vehicle based on demand information, and to determine the charging current of the vehicle in at least one sub-charging period within the charging period based on electricity price period information and the charging period, and to transmit the charging current in at least one sub-charging period to the charging control module in the vehicle.

[0110] The charging control module 208 is used to control the vehicle to charge during at least one sub-charging period according to the charging current, so as to complete the charging of the vehicle at the end of the charging period.

[0111] Optionally, the charging current determination module is also used to respond to the adjustment command applied to the display interface, determine the adjusted charging end time and the adjusted target state of charge; and based on the adjusted charging end time and the adjusted target state of charge, redetermine the charging current of the vehicle for at least one charging period.

[0112] Optionally, the charging current determination module can be a charging strategy optimization module, which can be used to determine the charging strategy, which may include the charging current corresponding to each sub-charging period.

[0113] Optionally, the above-mentioned electricity price period acquisition module can obtain the "peak-valley-flat" electricity price period information of charging pile A in real time through the wireless communication technology data interface with the charging pile management system.

[0114] Optionally, the aforementioned vehicle-mounted system may include a user interface module, through which users can obtain the electricity price and time period information of the public charging station and complete settings: charging cut-off SOC (100%) and target charging completion time (7 o'clock). Additionally, the interface will display the calculated optimal charging strategy and the real-time charging status after charging begins, allowing users to view and adjust the charging strategy according to their actual needs.

[0115] Optionally, the aforementioned charging strategy optimization module calculates and formulates the optimal charging strategy based on electricity price time information and user-set requirements. Under the premise that the user requires a full charge, the system automatically calculates the proportion of charging during off-peak hours and adjusts the charging power accordingly. From 6 PM to 9 PM, the charging control module sets the charging current and power to lower values, such as 5A and 1kW; from 10 PM to 6 AM, it sets the charging current and power to higher values, such as 32A and 7kW; and from 9 PM to 10 PM and 6 AM to 7 AM, it sets the charging current and power to higher values, such as 10A and 2kW, ultimately achieving a total charging of 63 kWh.

[0116] Optionally, the charging control module can automatically adjust and control the allowable charging current and voltage according to the charging strategy.

[0117] In this embodiment, by automatically acquiring peak-valley-flat electricity price information for public charging stations, an optimal charging strategy is automatically formulated, and the charging current and power are adjusted according to the strategy to achieve the lowest charging cost. Furthermore, uninterrupted charging from the charging stations can be achieved, allowing for on-demand deduction of parking fees. Moreover, this invention is simple to operate; users only need to view and adjust the charging strategy through the user interface, without requiring complex operations.

[0118] Figure 3 This is a schematic diagram of a charging period control system according to an embodiment of this application, as shown below. Figure 3As shown, the electricity price acquisition module can obtain the peak, valley, and normal-time electricity prices of the charging pile (i.e., electricity price period information) and transmit these prices to the user interface module for display. The user interface module can obtain demand information and, based on this, determine the charging end time and the target state of charge (SOC). It can then transmit the charging end time and target SOC to the charging strategy optimization module. The charging strategy optimization module, based on the charging end time, target SOC, and peak, valley, and normal-time electricity prices, determines the charging period and the charging power limit for each sub-period. Based on the charging power limit, it also determines the charging current limit for each sub-period. The charging optimization module can then transmit the charging current limit and charging power limit to the charging control module. The charging control module can then control the charging pile to charge the vehicle according to the target current and target voltage.

[0119] Optionally, the charging strategy optimization module can also transmit the charging power and time distribution to the user interface module for display.

[0120] This application proposes a vehicle charging control system. The system acquires electricity price time period information for charging piles and vehicle demand information via an electricity price time period acquisition module. The charging piles are used to charge the vehicle, and the electricity price time period information represents multiple electricity prices corresponding to the charging piles in multiple time periods. A selection command is executed on the vehicle's infotainment system display interface to determine the demand information indicated by the selection command. The demand information includes at least the vehicle's charging end time. A charging current determination module determines the vehicle's charging time period based on the demand information, and determines the charging current for at least one sub-charging time period based on the electricity price time period information and the charging time period. This charging current is then transmitted to the vehicle's charging control module. The charging control module controls the vehicle to charge within at least one sub-charging time period according to the charging current, completing charging at the charging end time. This allows for charging the vehicle at a lower cost, thus achieving the technical effect of reducing vehicle charging costs and solving the technical problem of high vehicle charging costs.
