[0018] By adopting the above technical solution, by considering the user's second historical charging information and basic information at the same time, we can have a more comprehensive understanding of the user's charging behavior and needs, improve the accuracy of target user identification, and by calculating the weights of the number of charging times and distances and associating them with the scores, we can better understand the user's use and demand for charging facilities and improve the use efficiency and management level of charging facilities.

[0026] The present application is further described in detail below in conjunction with the accompanying drawings.

[0027] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.

[0030] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0031] The embodiment of the present application provides a charging method for a charging pile, which can be executed by an electronic device, which can be a server or a terminal device, wherein the server can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a tablet computer, a desktop computer, etc., but is not limited thereto.

[0032] like Figure 1 As shown, a charging method for a charging pile, the main process of the method is described as follows (steps S101 to S108): Step S101, obtaining the user's current charging reservation information, the current charging reservation information including the target charging station, the expected charging start time, the expected charging end time, the current remaining power and the battery capacity; In this embodiment, the user sends charging reservation information to the electronic device through a mobile terminal. The charging reservation information includes but is not limited to the target charging station, expected charging start time, expected charging end time, current remaining power and battery capacity. The electronic device uses the received charging reservation information as the current charging reservation information, wherein the mobile terminal includes but is not limited to mobile phones and computers.

[0033] After obtaining the user's current charging reservation information, the following content is also included: Specifically, it is determined whether the charging time period corresponding to the current charging reservation information is a charging peak period; if so, the maximum charging power of the target charging pile corresponding to the current charging reservation information is reduced.

[0034] In this embodiment, a dedicated transformer is used in the target charging station. The target charging station is provided with multiple charging piles. The load of the dedicated transformer is only connected to the charging piles in the target charging station. The rated capacity of the dedicated transformer is known. When the charging station is in the peak charging period, a large number of electric vehicles will be charged at the same time. At this time, the transformer may be overloaded, causing a safety hazard in electricity use. Therefore, it is necessary to determine whether the charging time period corresponding to the current charging reservation information is in the peak charging period, so as to adjust the maximum working charging power of the charging piles in the target charging station and reduce the possibility that the charging power of the target charging station is greater than the rated power.

[0035] Among them, judging whether the charging time period corresponding to the current charging reservation information is a charging peak period includes: Determine whether the charging time period overlaps with the second preset time period; if there is an overlap, calculate the proportion of the overlapping part in the charging time period; determine whether the proportion is greater than the preset proportion; if it is greater than the preset proportion, determine that the charging time period corresponding to the current charging reservation information is in the peak charging period.

[0036] In this embodiment, the electronic device extracts a first start time and a first end time of a charging time period, and extracts a second start time and a second end time of a preset time. When the first start time is later than the second start time and the first end time is later than the second end time, it is determined that the charging time period overlaps with the preset time; when the first start time is earlier than the second start time and the first end time is earlier than the second end time, it is determined that the charging time period overlaps with the preset time; when the first start time is later than or equal to the second start time and the first end time is earlier than or equal to the second end time, it is determined that the charging time period overlaps with the preset time.

[0037] When the electronic device determines the overlapping part of the charging time period and the preset time period, the overlapping time of the overlapping part is compared with the total time of the charging time period to obtain a proportion. When the proportion is greater than the preset proportion, it is determined that the charging time period corresponding to the current charging reservation information is a peak charging period, where the preset proportion can be 90%.

[0038] When there is no overlap, the following also applies: Specifically, obtain the first historical charging information within a preset time period; calculate the average value of the charging power in the first historical charging information; calculate the difference between the average value and the rated power; determine whether the difference meets the preset conditions; if so, determine that the charging time period corresponding to the current charging reservation information is in the peak charging period.

[0039] Among them, the preset time period can be a time period within the charging time period one week before the current charging reservation information, extract the charging power in the first historical charging information, calculate the average value of the charging power, and the electronic device calculates the difference between the average value and the rated power. When the difference meets the preset condition, it is determined that the charging time period corresponding to the current charging reservation information is in the peak charging period, wherein the preset condition is that the difference is between 0 and 10.

[0040] Step S102, determining the charging duration based on the expected charging start time and the expected charging end time; In this embodiment, the electronic device extracts the expected charging start time and the expected charging end time from the current charging reservation information, and obtains the charging duration by subtracting the expected charging start time from the expected charging end time.

[0041] Step S103, calculating the amount to be charged based on the current remaining power and battery capacity; The amount to be charged can be obtained by subtracting the battery capacity from the current remaining power, wherein the battery capacity can be determined based on the user's historical charging information, and the current remaining power can be adjusted based on the user's historical charging preset information. The amount of power that the user needs to consume in the process of going to the target charging station is determined based on the historical expected start charging time and the remaining power when arriving at the target charging station in the user's historical charging preset information, and the current remaining power is adjusted based on the amount of power that needs to be consumed in the process of going to the target charging station. For example, the current remaining power is subtracted from the amount of power that needs to be consumed in the process of going to the target charging station to obtain a new remaining power, and the new remaining power is used as the current remaining power. When there are multiple historical charging preset information, the average value of the amount of power that needs to be consumed is taken. The amount of power that needs to be consumed in the process of going to the target charging station can also be calculated according to the season. For example, power consumption is faster in winter than in summer.

[0042] Step S104, determining a target charging power based on the charging time and the amount to be charged; In this embodiment, the target charging power can be calculated by the formula: target charging power = amount to be charged / charging time. For example, if the amount to be charged is 500mAh and the charging time is 3 hours, then the target charging power is 500mAh / 3h≈167mW.

[0043] Step S105, summing the total reserved charging power of the target charging station within the first preset time period and the target charging power to obtain the total charging power; In this embodiment, the electronic device obtains the target charging power corresponding to all charging reservation information within the first preset time period, sums up all the target charging powers to obtain the total reserved charging power, and sums up the target charging power in the current charging reservation information and the total reserved charging power to obtain the total charging power.

[0044] Step S106, determining whether the total charging power is greater than the rated power of the target charging station, if so, executing step S107, otherwise executing step S108; In this embodiment, the electronic device compares the total charging power with the rated power of the transformer to determine the charging mode.

[0045] Step S107, adjusting the target charging power, calculating the charging end time based on the adjusted target charging power, and sending the charging end time to the user's mobile terminal; When the total charging power is greater than the rated power of the target charging station, adjusting the target charging power specifically includes: calculating the difference between the rated power of the target charging station and the total reserved charging power to obtain the power difference; determining the remaining power value based on the power difference; and adjusting the target charging power based on the remaining power.

[0046] In this embodiment, the remaining power is determined by subtracting the rated power of the target charging station from the total reserved charging power. The target charging power needs to be reduced by a certain proportion to reduce the possibility of transformer load. In order to protect the transformer, the target charging power can be less than the remaining power. After the target charging power is adjusted, the charging end time is calculated by the adjusted target charging power, and the charging end time is sent to the user's corresponding mobile terminal so that the user can understand the latest charging plan.

[0047] Before adjusting the target charging power, it also includes: Obtain the user's second historical charging information and basic information; determine whether the user is a target user based on the second historical charging information and the basic information; if the user is a target user, obtain the number of target users existing at the target charging station during the charging time period; determine whether the number of target users exceeds a preset number; if it exceeds the preset number, execute the step of adjusting the target charging power, otherwise maintain the target charging power.

[0048] The preset number can be 2 or other values, which are not specifically limited. Before adjusting the target charging power, users can be screened and judged to timely discover and solve the problem of excessive charging load, thereby ensuring the safety and stability of the charging process. At the same time, the preset number can also be adjusted according to actual conditions to better meet the charging needs of users and the load requirements of the transformer.

[0049] Wherein, judging whether the user is a target user based on the second historical charging information and the basic information includes: Determine the number of charging times based on the second historical charging information; determine the distance between the user and the target charging station based on the basic information; obtain the weights corresponding to the number of charging times and the distance; calculate the score based on the number of charging times, the weight corresponding to the number of charging times, the distance and the weight corresponding to the distance; determine whether the score is greater than a preset score; if so, determine that the user is a target user.

[0050] In this embodiment, the electronic device obtains the second historical charging information of the user, which is the historical charging information of the user. The electronic device determines the historical charging times of the user through the second historical charging information, determines the home address or company address of the user according to the basic information of the user, and determines the distance information of the user from the target charging pile through the home address or company address. For example, the location information of the user and the target charging station can be obtained through GPS positioning or map API interface, and then the distance between the user and the target charging station can be obtained by using the distance calculation formula.

[0051] The electronic device has preset weights corresponding to the number of charging times and the distance. The electronic device calculates the score based on the number of charging times, the weight corresponding to the number of charging times, the distance, and the weight corresponding to the distance. For example, the number of charging times and the distance can be multiplied by the corresponding weights respectively, and then the obtained scores are added to obtain the user's total score, where the total score is the score mentioned above. When the user's score is greater than the preset score, the user is determined to be a target user; when the user's score is not greater than the preset score, the user is determined to be not a target user. The preset score can be set as needed and is not specifically limited.

[0052] Through the above steps, the user's charging times and distance can be determined based on the second historical charging information and basic information, and the user's score can be calculated to determine whether he or she is a target user. This can better understand the user's usage and demand for charging facilities and improve the efficiency of use and management of charging facilities.

[0053] Step S108, charging based on the target charging power.

[0054] In this embodiment, charging is performed according to the user's current scheduled charging information.
