[0001] The present invention relates to the technical field of staggered charging of charging piles, and in particular to a method and system for staggered charging of intelligent charging piles based on a cloud server. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as a power source and integrate advanced technologies in vehicle power control and driving. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. Common new energy vehicles mainly use lithium batteries as a power source;

[0003] With the continuous increase in the number of new energy vehicles, the cost of charging new energy vehicles is getting higher and higher. At the same time, the charging of new energy vehicles has caused increasing pressure on the power grid. For some cities with high electricity consumption, electricity charges are often charged by time segment. The existing new energy vehicle charging system cannot reasonably arrange the charging time of the car according to the current electricity cost situation and the time when the vehicle group uses the car when charging the car, resulting in the phenomenon of excessively high charging costs. Large-scale electricity consumption during peak periods is also likely to bring greater pressure to the power grid. How to reduce the cost of charging new energy vehicles and the pressure on the power grid has become a major research topic in the industry. Summary of the invention

[0004] The present invention provides a cloud server-based intelligent charging pile staggered charging method and system, which solves the problems mentioned in the above background technology of increased new energy charging costs and increasing pressure on the power grid caused by new energy vehicle charging.

[0008] Execute charging operations according to the charging strategy, including:

[0009] If the vehicle's current remaining power is higher than the target value set by the user, the charging operation will not be performed;

[0010] If the vehicle's current remaining power is lower than the target value set by the user;

[0011] The charging time required to reach the target value set by the user based on the charging pile power and the remaining power of the vehicle is recorded as the first time;

[0012] The second duration is the time from when the user inserts the charging port of the charging pile into the charging port of the car to the time of using the car set by the user.

[0024] The low-price charging time period whose end time is the same as the initial charging time is recognized as the target charging time period, and the low-price charging time period within the time period of the initial charging time and the continuous end charging time is also named as the target charging time period. If the continuous end charging time coincides with the start time of a certain low-price charging time period, this low-price charging time period is also recognized as the target charging time period;

[0025] Obtain the earliest time point in all the above target charging periods as the continuous charging start time;

[0026] Obtain the duration of the high-price charging period from the initial charging time to the continuous charging end time, and record it as the normal charging execution time;

[0027] In addition, the normal charging time must meet the time determination condition, which is: the normal charging time = the first time - the optimal charging time;

[0030] Calculate the sum of all low-price charging periods within the second duration, and record it as the optimal charging duration;

[0031] If the first duration is less than the optimal charging duration, then an initial charging time is selected during a low-price charging period;

[0032] Obtain the total duration of the low-price charging period from the initial charging time to the time when the user uses the car, and record it as the optimal charging duration;

[0033] It needs to be satisfied that the optimal charging duration = the first duration; then this initial charging moment is selected as the starting charging time point.

[0034] Optionally, the first duration is calculated using the following formula:

[0035] T=(MS) / P, where T is the first duration, M is the target value, S is the current remaining power of the vehicle, and P is the charging pile power.

[0036] Optionally, the car use time is set by the user, which specifically includes the following steps:

[0037] Get the user's daily driving status,

[0038] The driving state includes a driving state and a stopped state;

[0039] Calculate the number of days when the driving state is stopped, and record it as the number of days of stopping;

[0040] Calculate the number of days when the vehicle is in driving state, and record it as the number of driving times;

[0041] The date when the user inserts the charging pile charging interface into the car charging port is recorded as the cycle start date;

[0042] The date of the car use time set by the user is the end date of the cycle;

[0043] Calculate the time from the start date of the cycle to the end date of the cycle;

[0044] Based on the user's car usage record, determine whether the next car usage cycle is within a reasonable range, and adaptively push prompt information to prompt the user to confirm the car usage time again.

[0045] Optionally, judging whether the next car usage cycle is within a reasonable range based on the user's car usage record specifically includes:

[0046] If the number of days of stoppage ÷ the number of driving times ≦ the duration from the start date of the cycle to the end date of the cycle, a prompt message will be pushed to prompt the user to confirm the car usage time again.

[0047] Optionally, judging whether the next car usage cycle is within a reasonable range based on the user's car usage record specifically includes:

[0048] If the duration from the start date of the cycle to the end date of the cycle is less than or equal to the number of days stopped / number of times the vehicle is driven, then determine whether the schedule from the start date of the cycle to the end date of the cycle is of the same type. If it is the same type of schedule, directly confirm the vehicle use time currently set by the user;

[0049] If it is not the same type of schedule, a prompt message will be pushed to prompt the user to confirm the car usage time again.

[0050] Optionally, the determining whether the schedules from the period start date to the period end date are of the same type specifically includes:

[0051] Setting a schedule for each user, wherein the schedule includes working days and rest days;

[0052] Get all date information from the start date of the cycle to the end date of the cycle;

[0053] If all the date information from the start date of the cycle to the end date of the cycle only includes working days or rest days, it is considered to be a same-form schedule;

[0055] A system of a peak-shifting charging method for an intelligent charging pile based on a cloud server, a charging pile module, for charging a vehicle according to set vehicle charging information;

[0056] The information collection module is used to obtain the real-time power of the vehicle, vehicle charging information, the segmented electricity price information of the current charging pile location, the remaining charging time of the vehicle and the charging pile power, and transmit them to the cloud server;

[0057] The control module is connected to the charging module and the information collection module, and is used to control the charging module to execute the charging strategy according to the information collected by the information collection module.

[0058] The present invention has the following beneficial effects:

[0059] 1. The cloud server-based intelligent charging pile peak-shifting charging method collects the real-time power of the vehicle, the vehicle charging information, and the segmented electricity price information of the current charging pile location, and formulates a charging plan for the vehicle in combination with the segmented electricity price information of the charging pile location, and performs charging operations on the vehicle in combination with the charging plan, which effectively reduces the power supply pressure of the power grid during peak power consumption, and also effectively reduces the charging cost of the vehicle and the user's vehicle use cost;

[0060] In the charging plan, when the low-price charging period in the second time period can fully meet the current user's battery charging time requirements, that is, the first time period is less than the second time period, try to use the low-price charging period to charge the car, and concentrate the charging period to the time point closest to the car, so that it can be charged and used immediately. When the charging time in the low-price charging period is difficult to charge the car battery to the target value, select some high-price charging periods, and connect the charging time in the low-price charging period and the high-price charging period as much as possible to form a new charging start time, that is, charging is performed continuously at the start charging time, and charging is ended at the end charging time. This can reduce the number of times charging is started and stopped, which is beneficial to the health of the electric vehicle battery and the health of the charging pile.

[0061] 2. The cloud server-based intelligent charging pile staggered charging method calculates the interval duration of this driving and compares it with the historical average driving interval duration to determine whether the target driving interval this time is greater than the historical average driving interval. If it is greater than the historical average driving interval, the user is promptly reminded to reconfirm the vehicle usage time to avoid setting the vehicle usage time too long due to incorrect settings.

[0062] 3. The cloud server-based smart charging pile staggered charging method sets working days and rest days for different car users, and when all date information from the start date of the user's cycle to the end date of the cycle only contains working days or rest days, and the interval of this driving is less than the historical average driving interval, the user's currently set car use time is directly confirmed; otherwise, the user needs to be reminded to remind the user that there are dates of other nature in the time interval at this time, so as to reduce the phenomenon that the user's set car use time is unreasonable due to the existence of dates of other nature. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] Figure 1 It is a schematic diagram of the charging period of the present invention. DETAILED DESCRIPTION

[0064] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0065] Example 1, see Figure 1 The present invention provides the following technical solution: a cloud server-based intelligent charging pile peak-shifting charging method, comprising:

[0066] Set vehicle charging information and charge the vehicle, wherein the vehicle charging information includes vehicle use time and target value, vehicle use time refers to the time when the user needs to use the vehicle, and the target value refers to the percentage of the total battery capacity that the user hopes the battery will be charged each time; for example, the car manufacturer recommends that charging the battery to 80% is healthier for the battery, so the target value can be 80%, and the user can also set it according to their own needs, for example, set it to 100%;

[0067] Obtain the vehicle's real-time power, vehicle charging information, the segmented electricity price information of the current charging pile location, and the charging pile power, and transmit them to the cloud server; receive the vehicle charging information set by the user, and determine whether the vehicle's real-time power is higher than the target value set by the user;

[0068] If the vehicle's current remaining power is higher than the target value set by the user, the charging operation will not be performed;

[0069] If the current remaining power of the vehicle is lower than the target value set by the user, the charging operation is performed according to the charging strategy, including:

[0070] The charging time required to charge the vehicle from the remaining power to the target value set by the user is calculated based on the power of the charging pile and the natural power consumption of the vehicle when parked, and is recorded as the first time; the first time refers to the total time from the start of the charging operation of the charging pile to the end of the charging operation of the vehicle;

[0071] The second duration is from the time when the user inserts the charging interface of the charging pile into the charging port of the car to the time of using the car set by the user; after the user inserts the charging interface of the charging pile into the charging port of the car, the charging pile will select the most appropriate time to start charging the vehicle according to the charging strategy, instead of the charging pile immediately starting to charge the vehicle after the user inserts the charging interface of the charging pile into the charging port of the car;

[0072] Obtain segmented electricity price information; used to characterize the charging price change process over time;

[0073] The time segment corresponding to the low segment electricity price is defined as the low-price charging period;

[0074] The time segment corresponding to the high-segment electricity price is defined as the high-price charging period;

[0075] The car is charged according to the obtained first duration and second duration, so as to minimize the charging cost without delaying the user's use of the car.

[0076] The above method obtains segmented electricity price information and divides it into low-price charging periods and high-price charging periods, breaking down the entire charging process into different charging time periods. It tries to charge the car in the low-price charging segment to avoid charging the car at the charging pile during peak power consumption periods. This can not only reduce the huge pressure on the power grid caused by charging during peak power consumption, but also reduce the charging costs for users.

[0077] Further: the charging of the vehicle according to the acquired first duration and second duration specifically includes:

[0078] If the first duration is greater than the second duration, the charging pile will immediately perform the charging operation until the user uses the vehicle. Because when the first duration is greater than the second duration, the charging pile cannot reach the target value set by the user even if it continues to charge the vehicle. Therefore, the cost issue is no longer considered at this time. The vehicle should be charged as much as possible before the user uses the vehicle to meet the customer's needs as much as possible.

[0079] If the first duration is less than the second duration, the charging time period plan selection is executed first, and then the charging pile charging operation is executed; because when the first duration is greater than the second duration, the charging pile can meet the vehicle charging information set by the user, so while meeting the user's needs, the charging cost can be reduced as much as possible.

[0080] Further, the first performing charging time period scheme selection includes the following steps:

[0081] Calculate the sum of all low-price charging periods within the second duration, and record it as the optimal charging duration;

[0082] If the first duration is greater than the optimal charging duration, perform the following steps:

[0083] S1. Select an initial charging time and a continuous end charging time in all high-price charging time periods; the initial charging time is the end time of any low-price charging time period;

[0084] The low-price charging time period whose end time is the same as the initial charging time is recognized as the target charging time period, and the low-price charging time period within the time period of the initial charging time and the continuous end charging time is also named as the target charging time period. If the continuous end charging time coincides with the start time of a certain low-price charging time period, this low-price charging time period is also recognized as the target charging time period;

[0085] Obtain the earliest time point in all the above target charging periods as the continuous charging start time;

[0086] Obtain the duration of the high-price charging period from the initial charging time to the continuous charging end time, and record it as the normal charging execution time;

[0087] In addition, the normal charging time must meet the time determination condition, which is: the normal charging time = the first time - the optimal charging time;

[0088] S2. Obtain the start time and end time of all low-price charging periods except the target charging period, and perform charging at the start time of each low-price charging period, and stop charging at the end time of each low-price charging period, and perform charging at consecutive start times and stop charging at consecutive end times.

[0089] In the charging plan, when the low-price charging period in the second time period can fully meet the current user's battery charging time requirements, that is, the first time period is less than the second time period, try to use the low-price charging period to charge the car, and concentrate the charging period to the time point closest to the car, so that it can be charged and used immediately. When the charging time in the low-price charging period is difficult to charge the car battery to the target value, select some high-price charging periods, and connect the charging time in the low-price charging period and the high-price charging period as much as possible to form a new charging start time, that is, charging is performed continuously at the start charging time, and charging is ended at the end charging time. This can reduce the number of times charging is started and stopped, which is beneficial to the health of the electric vehicle battery and the health of the charging pile.

[0090] For example Figure 1 In the example, two low-price charging periods and one high-price charging period can meet user needs. In this case, the low-price charging periods 4 and 5 and the high-price charging period 2 can be regarded as target charging periods. At this time, the start time of the low-price charging 4 is used as the continuous start charging time to execute charging, and the end time of the low-price charging 5 is used as the continuous end charging time to stop charging.

[0091] Furthermore, the step of first performing the charging time period scheme selection includes the following steps:

[0092] Calculate the sum of all low-price charging periods within the second duration, and record it as the optimal charging duration;

[0093] If the first duration is less than the optimal charging duration, then an initial charging time is selected during a low-price charging period;

[0094] Obtain the total duration of the low-price charging period from the initial charging time to the time when the user uses the car, and record it as the optimal charging duration;

[0095] It needs to be satisfied that the optimal charging duration = the first duration; then this initial charging moment is selected as the starting charging time point.

[0096] The advantage of doing this is that the time when the charging pile finishes charging the car is as close as possible to the time when the user uses the car, achieving charge-and-use as much as possible, avoiding waste of resources while also reducing charging costs.

[0097] Specifically, the first duration is calculated by the following formula:

[0098] T=(MS) / P, where T is the first duration, M is the target value, S is the current remaining power of the vehicle, and P is the charging pile power.

[0099] Example 2, see Figure 1 This embodiment is a further improvement made on the basis of the embodiment 1. The specific vehicle use time is set by the user, and specifically includes the following steps:

[0100] Acquire the user's daily driving status, where the driving status includes a driving status and a stopped status;

[0101] Calculate the number of days when the driving state is stopped, and record it as the number of days of stopping;

[0102] The number of days corresponding to the driving state is calculated and recorded as the number of driving times. In this embodiment, as long as the driving state exists on a certain day, it is considered as one driving time. For example, if the driving state is from 11 o'clock in the evening of the previous day to 1 o'clock in the morning of the next day, the number of driving times is considered to be 2 times.

[0103] The date when the user inserts the charging pile charging interface into the car charging port is recorded as the cycle start date;

[0104] The date of the car use time set by the user is the end date of the cycle;

[0105] Calculate the duration from the start date of the cycle to the end date of the cycle, and the duration is expressed in days;

[0106] Based on the user's car usage record, determine whether the next car usage cycle is within a reasonable range, and adaptively push prompt information to prompt the user to confirm the car usage time again.

[0107] Furthermore, judging whether the next car use cycle is within a reasonable range based on the car use record of the user specifically includes:

[0108] If the number of days of stoppage ÷ the number of driving times ≦ the duration from the start date of the cycle to the end date of the cycle, a prompt message will be pushed to prompt the user to confirm the car usage time again.

[0109] When this situation occurs, the method calculates the interval duration of this driving and compares it with the historical average driving interval duration to determine whether the target driving interval this time is greater than the historical average driving interval. If it is greater than the historical average driving interval, the user is promptly reminded to reconfirm the driving time to avoid the driving time being set too long due to incorrect settings.

[0110] It should also be noted that judging whether the next car use cycle is within a reasonable range based on the user's car use record specifically includes:

[0111] If the duration from the start date of the cycle to the end date of the cycle is less than or equal to the number of days stopped / number of times the vehicle is driven, then determine whether the schedule from the start date of the cycle to the end date of the cycle is of the same type. If it is the same type of schedule, directly confirm the vehicle use time currently set by the user;

[0112] If it is not the same type of schedule, a prompt message will be pushed to prompt the user to confirm the car usage time again.

[0113] Specifically, the determination of whether the schedule from the cycle start date to the cycle end date is of the same type specifically includes:

[0114] A schedule is set for each user, and the schedule includes working days and rest days. The time definitions of working days and rest days are different for different vehicle users. For example, most workers work from Monday to Friday and rest days are from Saturday to Sunday, while some workers in education professions work from Wednesday to Sunday and rest days are from Monday to Tuesday. The starting points of working days and rest days for people in different professions are also different. Therefore, it is necessary to set working days and rest days suitable for different vehicle users.

[0115] Get all date information from the start date of the cycle to the end date of the cycle;

[0116] If all the date information from the start date of the cycle to the end date of the cycle only includes working days or rest days, it is considered to be a same-form schedule;

[0117] If all the date information from the start date of the cycle to the end date of the cycle includes both working days and holidays, it is considered that they are not the same type of schedule.

[0118] First, the working days and rest days are set for different car users. When all the date information from the start date of the user's cycle to the end date of the cycle only contains working days or rest days, and the interval of this driving is less than the historical average driving interval, the car use time currently set by the user is directly confirmed; otherwise, the user needs to be reminded to remind the user that there are dates of other nature in the current time interval, so as to reduce the phenomenon that the car use time set by the user is unreasonable due to the existence of dates of other nature.

[0119] A cloud server-based intelligent charging pile peak-shifting charging system, comprising a charging pile module, for charging a vehicle according to set vehicle charging information;

[0120] The information collection module is used to obtain the real-time power of the vehicle, vehicle charging information, the segmented electricity price information of the current charging pile location, the remaining charging time of the vehicle and the charging pile power, and transmit them to the cloud server;

[0121] The control module is connected to the charging module and the information collection module, and is used to control the charging module to execute the charging strategy according to the information collected by the information collection module.

[0122] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0123] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
