[0003] This application relates to the technical field of vehicle charging, and more specifically, to a scheduled charging method, product, and vehicle. Background Technology

[0004] In current vehicle charging reservation schemes, users set a time slot for charging and then charge their vehicles during that time. To encourage orderly charging when vehicles are not in use at night, most regions offer low nighttime electricity prices to guide electric vehicle owners to charge during off-peak hours. However, in existing reservation charging schemes, if a large number of electric vehicles start charging at the same time at night, it can cause excessive instantaneous pressure on the power distribution network, impacting its instantaneous power output. Summary of the Invention

[0020] In some embodiments of this application, after calculating the vehicle's charging time period, the method further includes:

[0021] If the full charge period is longer than the scheduled charging period, the actual charging start time of the vehicle is randomly adjusted based on the scheduled charging period and the preset maximum delay period.

[0022] In some embodiments of this application, the calculation of the vehicle's charging time period includes:

[0023] The time required to fully charge the vehicle is calculated based on the vehicle's total battery capacity, current remaining capacity, and the charging power of the charging station currently connected to the vehicle.

[0024] In some embodiments of this application, the formula for calculating the full charge time of the vehicle, based on the vehicle's total battery capacity, current remaining capacity, and the charging power of the charging station currently connected to the vehicle, is: h=E×(1-SoC) / P

[0025] Where h is the full charge time period; E is the total battery capacity; SoC is the current remaining capacity; and P is the charging power of the charging station currently connected to the vehicle.

[0026] In some embodiments of this application, when the full charging time period is shorter than the scheduled charging time period, the actual charging start time of the vehicle is randomly adjusted based on the scheduled charging time period and the full charging time period, including:

[0028] The first charging delay time is determined based on the time difference and the first random number;

[0029] The actual charging start time of the vehicle is obtained based on the first charging delay time.

[0030] In some embodiments of this application, the actual charging start time of the vehicle is obtained based on a first charging delay time, including:

[0031] The actual charging start time of the vehicle is calculated based on the scheduled charging start time and the first charging delay time corresponding to the scheduled charging time period.

[0032] In some embodiments of this application, when the full charge time period is shorter than the scheduled charging time period, the formula for randomly adjusting the actual charging start time of the vehicle based on the scheduled charging time period and the full charge time period is: he1=h0+r1×((h t -h0)-h)

[0033] Where, he1 is the actual charging start time of the vehicle when the full charging period is shorter than the scheduled charging period; r1 is a first random number between 0 and 1; r1×((h t -h0)-h) represents the first charging delay time; h0 is the scheduled charging start time; h t The scheduled end time for charging; (h) t -h0) represents the scheduled charging time period; h represents the full charging time period.

[0035] If the full charge period is longer than the scheduled charging period, the second charging delay time is determined based on the preset maximum delay period and the second random number.

[0038] The actual charging start time of the vehicle is calculated based on the scheduled charging start time and the second charging delay time corresponding to the scheduled charging time period.

[0039] In some embodiments of this application, when the full charging time period is longer than the scheduled charging time period, the formula for randomly adjusting the actual charging start time of the vehicle based on the scheduled charging time period and the preset maximum delay time period is: he2=h0+r2×h s

[0040] Where, he2 is the actual charging start time of the vehicle when the full charging period is longer than the scheduled charging period; h0 is the scheduled charging start time; r2 is a second random number between 0 and 1; h s The preset maximum delay time period; r2×h s This is the second charging delay time.

[0041] In some embodiments of this application, after calculating the vehicle's charging time period, the method further includes:

[0042] If the full charge period is equal to the scheduled charging period, the scheduled charging start time corresponding to the scheduled charging period will be used as the actual charging start time of the vehicle.

[0057] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0058] With the rapid development of electric vehicles, the demand for vehicle charging is also growing rapidly. If the rapidly growing demand for electric vehicle charging is not regulated, it can easily cause load shocks to the power grid and affect the stability and security of the power grid.

[0059] The current scheduled charging solution allows users to set a scheduled charging time period through a mobile app or vehicle app, and then charge the vehicle during the scheduled charging time period.

[0060] To encourage users to charge their vehicles in an orderly manner when they are not using them at night, most regions have set up low electricity prices at night to guide electric vehicle owners to charge during off-peak hours. However, in the current scheduled charging schemes, if a large number of electric vehicles start charging at the same time at night, it will also cause excessive instantaneous pressure on the power distribution network, impacting the instantaneous power of the power distribution network, seriously affecting the operating efficiency and capacity of the power distribution network, resulting in uneconomical power distribution capacity and difficulties in registering charging stations.

[0061] Therefore, this application provides a scheduled charging method that can reduce the problem of excessive instantaneous pressure on the power distribution network caused by a large number of electric vehicles starting to charge at the same time.

[0062] Referring to Figure 1, a flowchart of a scheduled charging method according to an embodiment of this application is shown. The method may specifically include the following steps:

[0063] S101: Determine the actual charging start time of the vehicle based on the scheduled charging time period.

[0064] Specifically, after a user connects their vehicle to the charging gun of a charging station, they can schedule AC charging through a mobile app or the vehicle's app to initiate a scheduled charging request. The scheduled charging request includes the start and end times of the scheduled charging, and the scheduled charging time period can be determined based on the start and end times of the scheduled charging.

[0065] Then, the actual charging start time is determined based on the scheduled charging time period. The actual charging start time is the charging start time after a random delay based on the scheduled charging start time.

[0066] S102: Charge the vehicle according to the actual charging start time.

[0067] For example, due to the incentive of low electricity prices at night, many vehicles may schedule to start charging at 22:00. In order to reduce the problem of excessive instantaneous pressure on the power distribution network caused by a large number of vehicles starting to charge at 22:00 at the same time, the actual charging start time of each vehicle can be randomly delayed based on the scheduled charging time of each vehicle. This reduces the problem of excessive instantaneous pressure on the power distribution network caused by a large number of electric vehicles starting to charge at the same time.

[0068] Referring to Figure 2, a flowchart of a scheduled charging method provided in an embodiment of this application is shown. The method may specifically include the following steps:

[0069] S201: Detect whether the vehicle meets the random delay condition.

[0070] For example, when a user connects the vehicle to the charging gun of the charging station, they can initiate a scheduled charging operation through an app such as a mobile phone app or a vehicle app to schedule AC charging. After responding to the user's scheduled charging request, the vehicle can first check whether the vehicle meets the random delay conditions.

[0071] In one feasible implementation, the vehicle's compliance with random delay conditions can be determined based on the type of charging station it is currently connected to. This is because some charging stations now have charging regulation functions and are grid-friendly. When a vehicle is charged through such a grid-friendly charging station, it can be charged according to the charging station's own charging process.

[0072] Specifically, the type of the charging station currently connected to the vehicle is obtained; if the type of the charging station currently connected to the vehicle is not a smart charging station, the vehicle meets the random delay condition.

[0073] Smart charging piles are used to adjust the charging information of charging piles when charging vehicles based on grid load and electricity price. Smart charging piles can control vehicles to charge in an orderly manner based on grid load and electricity price, such as charging vehicles that have made reservations to charge during the period when electricity price is the lowest and grid load is sufficient. They can also dynamically adjust the charging information of charging piles during the charging process based on grid load and electricity price, including charging start and stop and charging power.

[0074] When the charging station currently connected to the vehicle is a smart charging station, the smart charging station can adjust the charging information according to the power grid information, which is friendly to the power grid and is not likely to cause instantaneous pressure on the power grid. Therefore, it can normally execute the charging scheduling based on the smart charging station and carry out the vehicle's scheduled charging process.

[0075] If the charging station currently connected to the vehicle is not a smart charging station, the instantaneous pressure on the power distribution network will be too high when multiple vehicles start charging at the same time. In this case, the vehicle meets the random delay condition and the actual charging start time when the vehicle is scheduled to charge needs to be corrected.

[0076] For example, smart charging piles may include orderly charging piles and V2G (Vehicle-to-Grid) charging piles. In actual implementation, smart charging piles may also include other charging piles that dynamically adjust the charging information of the vehicle charging process based on grid load and / or grid electricity price, etc. This embodiment does not impose any restrictions.

[0077] Specifically, when the type of charging station currently connected to the vehicle is not an ordered station, the vehicle meets the random delay condition.

[0078] Ordered charging piles are charging piles that adjust charging power based on grid information or grid dispatch. In actual implementation, when a vehicle is currently connected to an ordered charging pile, the ordered charging pile can accept charging start / stop and charging power adjustment based on the ordered charging pile's CC (Connection Confirm) high / low level signal and CP (Control Pilot) duty cycle signal. Through grid dispatch, such as receiving dispatch from charging aggregators or virtual power plant operators, the charging is adjusted, and the vehicle becomes a flexible load, which is both grid-friendly and may reduce charging costs for car owners.

[0079] Furthermore, it is determined that the vehicle meets the random delay condition when the type of charging pile currently connected to the vehicle is not a V2G pile.

[0080] V2G charging piles can adjust vehicle charging and discharging behavior based on grid information. When the vehicle is currently connected to a V2G charging pile, it receives instructions from the V2G charging pile to charge or discharge based on the V2G charging pile's CC high and low level signals, CP duty cycle signals, and any additional communication signals that may be attached between the vehicle and the charging pile. Furthermore, the V2G charging pile controls the vehicle to discharge in an orderly manner when the grid electricity price is high and controls the vehicle to charge in an orderly manner when the grid electricity price is low, thereby reducing charging costs without affecting the vehicle's electricity usage experience, while also being friendly to the transformer substation and distribution network.

[0081] Therefore, when the charging station connected to the vehicle is an ordered charging station or a V2G smart charging station, it can be charged directly according to the charging adjustment strategy corresponding to the smart charging station without delay. That is, when the charging station connected to the vehicle is an ordered charging station, the random delay condition is not met.

[0082] In another feasible implementation, in addition to determining the type of charging station currently connected to the vehicle, it is also possible to further detect whether the vehicle meets the random delay condition based on the vehicle's current location when the charging appointment is scheduled.

[0083] Considering that when vehicles are charged at home charging stations or community charging stations within a user's residence, it is mostly a scenario where the vehicle is not in use. However, when charging at locations outside the user's residence, such as the user's company or public charging stations, it is mostly a scenario where the vehicle is in use but the battery is low. Therefore, if random delayed scheduled charging is adopted for the scenario where the vehicle is in use but the battery is low, it may not be able to meet the user's battery demand.

[0084] Therefore, in this embodiment, when determining whether the detected vehicle meets the random delay condition, it may also include obtaining the current location of the vehicle when it is connected to the charging pile; if the type of the charging pile currently connected to the vehicle is not a smart charging pile, and the current location of the vehicle is within the preset delayed charging reservation range, the vehicle meets the random delay condition.

[0085] If the vehicle is currently connected to a smart charging station, or if the vehicle's current location is not within the preset delayed charging range, the vehicle does not meet the random delay condition.

[0086] In actual implementation, the preset delayed charging range can be the area corresponding to the user's residence, such as the area of ​​the user's residential community or the area of ​​commonly used charging stations near the user's residence. This allows for random delayed charging of the vehicle when the user is not using the vehicle at home. Specifically, the size of the preset delayed charging range can be set according to the actual application needs, and this embodiment does not impose any restrictions.

[0087] By determining whether the vehicle meets the random delay conditions based on whether the charging pile currently connected to the vehicle is a smart charging pile and whether the vehicle's current location is within the preset delayed charging range, the system can randomly delay scheduled charging at charging piles that are not grid-friendly or when the vehicle is idle. This reduces the impact on the power grid caused by a large number of vehicles starting to charge simultaneously without affecting the normal use of the vehicle.

[0088] S202: If the vehicle meets the random delay condition, determine the actual charging start time of the vehicle based on the scheduled charging time period.

[0089] Specifically, the process of determining the actual charging start time of a vehicle based on the scheduled charging time period includes the following steps:

[0090] A1: Get the scheduled charging time slot.

[0091] Specifically, after the user connects the vehicle and the charging gun of the charging station, the user's scheduled charging request is first obtained. The user's scheduled charging request includes the scheduled charging start time and scheduled charging end time. The size of the scheduled charging time period can be determined based on the scheduled charging start time and scheduled charging end time. For example, the scheduled charging time period = scheduled charging end time ht - scheduled charging start time h0.

[0092] In practice, the start and end times of the scheduled charging can be integers, such as 22:00, which can be recorded as 22. Alternatively, the start and end times can be non-integers, such as 22:05. Non-integer times should be converted to numerical values, such as converting 22:05 to the numerical value 22.083.

[0093] If the reservation period spans beyond 24:00, the time of the next day will be recorded as 24+ hours. For example, if a user's reservation charging start time is 22:00 on the same day and the reservation charging end time is 6:00 on the next day, then the reservation charging end time will be recorded as 30.

[0094] A2: Calculate the time period for the vehicle to fully charge.

[0095] For example, the time required to fully charge the vehicle is calculated based on the vehicle's total battery capacity, current remaining capacity, and the charging power of the charging station currently connected to the vehicle.

[0096] The formula for calculating the full charge time of a vehicle can be: h = E × (1 - SoC) / P

[0097] Where h is the full charge time period; E is the total battery capacity; SoC is the current remaining capacity; and P is the charging power of the charging station currently connected to the vehicle.

[0098] A3: If the full charge time period is shorter than the scheduled charging time period, the actual charging start time of the vehicle will be randomly adjusted based on the scheduled charging time period and the full charge time period.

[0099] Specifically, if the full charge period is shorter than the scheduled charging period, the time difference between the scheduled charging period and the full charge period is first determined.

[0100] Then, based on the time difference and the first random number, the first charging delay time is determined.

[0101] Finally, based on the first charging delay time, the actual charging start time of the vehicle is obtained.

[0102] Specifically, the actual charging start time of the vehicle can be calculated based on the scheduled charging start time and the first charging delay time corresponding to the scheduled charging time period.

[0103] For example, when the full charge period is shorter than the scheduled charging period, the formula for randomly adjusting the actual charging start time of the vehicle based on the scheduled charging period and the full charge period is: he1=h0+r1×((h t -h0)-h)

[0104] Where, he1 is the actual charging start time of the vehicle when the full charging period is shorter than the scheduled charging period; r1 is a first random number between 0 and 1; r1×((h t -h0)-h) represents the first charging delay time; h0 is the scheduled charging start time; h t The scheduled end time for charging; (h) t -h0) represents the scheduled charging time period; h represents the full charging time period.

[0105] Assuming vehicle A is scheduled to be charged between 22:30 today and 6:00 the next day, then the start time of the scheduled charging is h0 = 22.5, and the end time of the scheduled charging is h... t =30; Scheduled charging time period =h t -h0 = 30 - 22.5 = 7.5;

[0106] Vehicle A has a total battery capacity E of 50 kWh, a current remaining capacity SoC (State of Charge) of 35%, and a charging power P of the charging station currently connected to vehicle A of 7 kW. Therefore, the full charge time h of vehicle A is 50 × (1 - 35%) / 7 = 4.643.

[0107] According to the scheduled charging end time h t Comparing with the full charging time period h, 30 - 4.643 = 25.357. 25.357 is converted to the time 1:21 the next day. That is, the latest time to start charging vehicle A is from 1:21 the next day to fully charge vehicle A. Therefore, the actual charging start time of vehicle A can be randomly determined between 22:30 today and 1:21 the next day.

[0108] Since the full charge time period of 4.643 is less than the scheduled charging time period of 7.5, taking the first random number r1 as 0.8147 as an example, the actual charging start time after the random delay is: he1=h0+r1×((h t -h0)-h)=22.5+0.8147×(7.5-4.643)=24.828;

[0109] Convert 24.828 to a time and round it up to 0:50 the next day; that is, the actual charging of vehicle A will begin at 0:50 the next day.

[0110] If the first random number r1 is 0, then he1 = h0 = 22.5, meaning charging starts at the scheduled charging start time of 22:30; if the first random number r1 is 1, then he1 = h0 + ((h t -h0)-h)=25.357, meaning that charging vehicle A will begin and be fully charged no later than 1:21 the next day.

[0111] If the full charge time period is shorter than the scheduled charging time period, it indicates that the scheduled charging time period set by the user has redundancy, and the vehicle is sufficient to be fully charged within the scheduled charging time period. The first charging delay time is determined based on the time difference between the scheduled charging time period and the full charge time period and the first random number. Even if the actual charging is delayed by the first charging delay time, the vehicle can still be fully charged. This does not affect the vehicle's full charge status and can also randomly delay the start time of charging, reducing the impact on the power grid caused by a large number of vehicles starting to charge at the same time.

[0112] For example, if the users of vehicle 1 and vehicle 2 both schedule to charge between 22:00 today and 6:00 the next day, and both vehicle 1 and vehicle 2 can be fully charged within the scheduled charging time, the first charging delay time corresponding to vehicle 1 and vehicle 2 will also be different because the charging time periods and / or the first random number are different. That is, although vehicle 1 and vehicle 2 both schedule to start charging from 22:00, the actual charging start time is not the same, thus staggering the charging start time of vehicle 1 and vehicle 2.

[0113] A4: If the full charge time period is longer than the scheduled charging time period, the actual charging start time of the vehicle will be randomly adjusted based on the scheduled charging time period and the preset maximum delay time period.

[0114] Specifically, if the full charge period is longer than the scheduled charging period, the second charging delay time is first determined based on the preset maximum delay period and the second random number.

[0115] Then, based on the second charging delay time, the actual charging start time of the vehicle is obtained. For example, the actual charging start time of the vehicle can be calculated based on the scheduled charging start time corresponding to the scheduled charging time period and the second charging delay time.

[0116] For example, when the full charge period is longer than the scheduled charging period, the formula for randomly adjusting the actual charging start time of the vehicle based on the scheduled charging period and the preset maximum delay period is: he2=h0+r2×h s

[0117] Where, he2 is the actual charging start time of the vehicle when the full charging period is longer than the scheduled charging period; h0 is the scheduled charging start time; r2 is a second random number between 0 and 1; h s The preset maximum delay time period; r2×h s This is the second charging delay time.

[0118] Suppose that for vehicle B, user B schedules charging from 22:30 today to 6:00 the next day. Then the scheduled charging start time h0 = 22.5, and the scheduled charging end time h... t =30;

[0119] Scheduled charging time period = h t -h0 = 30 - 22.5 = 7.5;

[0120] The total battery capacity E of vehicle B is 90 kWh, the current remaining capacity SoC is 10%, and the charging power P of the charging pile currently connected to vehicle B is 7 kW. Then the full charge time h of vehicle B is 90 × (1 - 10%) / 7 = 11.571.

[0121] Since the full charge time period of 11.571 is greater than the scheduled charging time period of 7.5, it indicates that vehicle B cannot be fully charged within the user's scheduled charging time period.

[0122] With the maximum delay time period h s Taking a time interval of 0.5 (30 min) and a second random number r2 of 0.8147 as an example, the actual charging start time after the random delay is:

[0123] he2=h0+r2×h s =22.5 + 0.8147 × 0.5 = 22.907. 22.907 translates to 22:54, meaning the vehicle can start charging at 22:54.

[0124] If r2 is 0, then he2 = h0, and charging will begin immediately at the scheduled charging start time, which is 22:30 in the evening; if r2 is 1, then he2 = h0 + h s =22.5+0.5=23, meaning that charging will be delayed for the maximum delay period, starting from 23:00.

[0125] If the full charge time period is longer than the scheduled charging time period, it means that the vehicle cannot be fully charged within the scheduled charging time period set by the user. In this case, a maximum delay time period can be preset. The maximum delay time period can be preset by the vehicle manufacturer according to the actual application needs. However, in order not to seriously affect the user's demand for vehicle power, the maximum delay time period needs to be set reasonably. For example, in this embodiment, the maximum delay time period is set to 15 minutes or 30 minutes. The power charged by the vehicle within 30 minutes has a smaller impact on the user's vehicle use.

[0126] By setting a reasonable maximum delay period, the start time of charging can be randomly delayed while minimizing the impact on users' vehicle usage, thereby reducing the impact on the power grid caused by a large number of vehicles starting to charge at the same time.

[0127] A5: When the full charge period is equal to the scheduled charging period, the scheduled charging start time corresponding to the scheduled charging period shall be taken as the actual charging start time of the vehicle.

[0128] If the scheduled charging time period set by the user happens to be the time when the vehicle can be fully charged, the need to fully charge the vehicle can be given priority. The scheduled charging start time corresponding to the scheduled charging time period can be used as the actual charging start time of the vehicle. That is, the actual charging will start from the scheduled charging start time set by the user.

[0129] In actual implementation, a short delay time can be set when the full charging time period is equal to the scheduled charging time period, such as a short delay time of 5 minutes. This allows for random adjustment of the actual charging start time within the 5-minute range.

[0130] S203: Charge the vehicle according to the actual charging start time.

[0131] When the actual charging start time is determined based on the user-set scheduled charging time period and the size of the vehicle's full charge time period, charging the vehicle according to the actual charging start time can effectively reduce the impact on the power grid caused by a large number of vehicles starting to charge at the same time, and significantly alleviate charging peaks in the distribution area.

[0132] Referring to Figure 3, an execution flowchart of the scheduled charging method provided in an embodiment of this application is shown. In one feasible implementation, the method specifically includes:

[0133] Upon detecting a user's scheduled charging request, the system first checks whether the vehicle meets the random delay condition. For example, it can first determine whether the type of charging pile currently connected to the vehicle is a smart charging pile. This could include determining whether the type of charging pile currently connected to the vehicle is an ordered charging pile or a V2G charging pile. Then, it determines whether the vehicle's current location is within the preset delayed scheduled charging range. The order of determining the type of charging pile and the vehicle's current location can be defined according to the actual application requirements. In this embodiment, the process of determining the type of charging pile first and then determining the vehicle's current location is taken as an example.

[0134] If the charging station currently connected to the vehicle is a smart charging station, the charging process is executed according to the charging schedule corresponding to the smart charging station.

[0135] If the vehicle's current location is not within the preset delayed charging range, charging will proceed according to the normal AC charging process.

[0136] If the charging station currently connected to the vehicle is not a smart charging station, and the vehicle's current location is within the preset delayed charging reservation range, the random delayed charging reservation process will be entered, that is, the actual charging start time of the vehicle will be determined based on the reserved charging time period.

[0137] Finally, the vehicle is charged according to the actual charging start time.

[0138] Referring to Figure 4, an execution flowchart for determining the actual charging start time provided in an embodiment of this application is shown. In one feasible implementation, determining the actual charging start time of a vehicle based on a scheduled charging time period may include the following process:

[0139] Obtain the scheduled charging time period from the user's scheduled charging request and calculate the vehicle's full charge time period.

[0140] Specifically, the user's scheduled charging request includes the scheduled charging start time h0 and the scheduled charging end time h0. t The length of the scheduled charging time period is h. t -h0.

[0141] The time required to fully charge the vehicle is calculated based on the vehicle's total battery capacity, current remaining capacity, and the charging power of the charging station currently connected to the vehicle.

[0142] Specifically, the formula for calculating the vehicle's full charge time can be: h = E × (1 - SoC) / P

[0143] Where h is the full charge time period; E is the total battery capacity; SoC is the current remaining capacity; and P is the charging power of the charging station currently connected to the vehicle.

[0144] Then determine the relationship between the full charge time period and the scheduled charging time period.

[0145] If the full charge period is shorter than the scheduled charging period, the actual charging start time of the vehicle is randomly adjusted based on the scheduled charging period and the full charge period.

[0146] Specifically, when the full charge period is shorter than the scheduled charging period, the formula for randomly adjusting the vehicle's actual charging start time based on the scheduled charging period and the full charge period is: he1=h0+r1×((h t -h0)-h)

[0147] Where, he1 is the actual charging start time of the vehicle when the full charging period is shorter than the scheduled charging period; r1 is a first random number between 0 and 1; h0 is the scheduled charging start time; h t The scheduled end time for charging; (h) t -h0) represents the scheduled charging time period; h represents the full charging time period.

[0148] If the full charge period is longer than the scheduled charging period, the actual charging start time of the vehicle is randomly adjusted based on the scheduled charging period and the preset maximum delay period.

[0149] Specifically, when the full charging period is longer than the scheduled charging period, the formula for randomly adjusting the actual charging start time of the vehicle based on the scheduled charging period and the preset maximum delay period is: he2=h0+r2×h s

[0150] Where, he2 is the actual charging start time of the vehicle when the full charging period is longer than the scheduled charging period; h0 is the scheduled charging start time; r2 is a second random number between 0 and 1; h s This is the preset maximum delay time period.

[0151] If the full charge period is equal to the scheduled charging period, the scheduled charging start time corresponding to the scheduled charging period will be taken as the actual charging start time of the vehicle.

[0152] The scheduled charging method provided in this embodiment can, under the condition that the vehicle is off-grid or there is no orderly charging available for smart charging piles, modify the scheduled charging time period after the user schedules the charging, and determine the actual charging start time after random delay. This can reduce the problem of excessive instantaneous pressure on the distribution network caused by a large number of vehicles starting to charge at the same scheduled start time, significantly alleviate the charging peak in the distribution substation, and this method does not rely on charging equipment or edge control terminals, and can improve the problem of substation overload at low cost.
