[0002] With the booming development of the new energy industry, electric vehicles are becoming increasingly common in daily life, and more and more regions are actively deploying charging stations. Charging stations, as facilities providing charging services for electric vehicles, typically have multiple charging piles installed to meet the needs of multiple electric vehicles charging simultaneously. The use of charging piles also poses a challenge to the grid's carrying capacity. Currently, most charging piles use intelligent charging scheduling algorithms to charge electric vehicles, meaning they charge in a cost-minimizing manner while meeting user electricity needs within a certain time frame. This saves users on electricity costs, but under the current time-of-use pricing system, it can easily lead to peak charging periods during relatively low-price periods, resulting in grid overload during peak charging times.

This method enables additional charges to be applied according to a pre-defined additional charging standard during peak charging periods, thereby changing the scheduling mode of the intelligent charging scheduling algorithm from the pricing perspective. This effectively avoids grid overload during peak charging periods, achieving peak shaving and valley filling effects for the grid load. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0026] It should be noted that, unless otherwise specified, the various features in the embodiments of this invention can be combined with each other, all of which are within the protection scope of this invention. Furthermore, although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than the module division in the device or the order in the flowchart. Moreover, the terms "first," "second," and "third" used in this invention do not limit the data or execution order, but only distinguish identical or similar items with essentially the same function and effect.

[0027] To describe this application in more detail, a charging billing system according to this application is first introduced. This charging billing system includes a billing server and a charging management device. The billing server establishes a communication connection with the charging management device, which manages charging stations. The charging station includes at least one charging pile. For an example, please refer to [link to example]. Figure 1 The present application provides a charging billing system 10, which includes a billing server 101 and a charging management device 102. The charging management device 102 establishes a communication connection with the billing server 101, and the charging management device 102 is also connected to a first charging pile 1021 and a second charging pile 1022 in the charging station (understandably, in other embodiments, the number of the charging group can be any number).

[0028] It should be noted that the billing server 101 is used to receive the charging power information from the charging management device 102, and to statistically calculate the charging station's billing information based on this charging power information. In one feasible implementation, the charging management device 102 collects real-time electrical energy data between the charging pile and the power grid, including charging duration, current, voltage, power, and other information, and sends it to the billing server 101. The billing server 101 calculates the charging fee according to different billing strategies (by time, power, electricity, etc.), and can provide a secure payment channel for station owners to pay charging fees online by integrating with a payment system.

[0029] It should also be noted that the charging management device 102 is an intelligent management device that integrates information on electric vehicles currently charging, grid load information, and charging pile charging information, primarily for managing charging stations. A charging station is a facility used to provide charging services for electric vehicles, typically located in cities, highways, or commercial areas, and may include multiple charging piles. The charging pile acts as a bridge connecting the electric vehicle and the power source, providing charging output at different power levels to power the electric vehicle. In one embodiment, the charging pile may consist of a metal casing, a charging plug, a controller, and a communication module.

[0030] In some feasible implementations, the charging management device 102 can consist of one or more workstations or servers, enabling monitoring and data collection and querying of charging piles, as well as data processing and analysis of the entire charging station. The charging management device 102 can also make decisions on the allocation of charging time and power based on real-time data, and send corresponding decision instructions to each charging pile under the charging station for execution.

[0031] Understandably, the above Figure 1 The billing server 101, charging management device 102 and charging station shown are only examples. In actual situations, equipment or modules can be integrated, adjusted or added as needed. For example, the charging station may also include a power supply system, which mainly provides power to the charging equipment. It may consist of primary equipment (switches, transformers, lines, etc.) and secondary equipment (including detection, protection, control devices, etc.), source filtering devices, etc. This application does not impose any restrictions on this.

[0032] Based on the above-described charging billing system, the charging billing method provided in this application can be implemented. Please refer to the following: Figure 2 This is a flowchart illustrating a charging billing method provided in an embodiment of this application. Figure 2 The charging billing methods shown may include:

[0033] S201. The charging management device receives the charging power generated by each charging pile after scheduling based on the intelligent charging scheduling algorithm.

[0034] This paper defines the intelligent charging scheduling algorithm as one that minimizes charging costs while meeting the required charging capacity within a preset charging time range.

[0035] In one embodiment, prior to step S201, the method may further include:

[0036] The charging management device receives charging demand data sent by the charging pile and, based on the intelligent charging scheduling algorithm, schedules the charging time of the charging pile according to the charging demand data to minimize the charging cost of the charging pile.

[0037] The charging demand data includes at least the charging start time, charging duration, required charging capacity, and vehicle maximum power. It should be noted that the vehicle's maximum power refers to the maximum power limit of the vehicle during charging. This value is automatically obtained by the charging station after the electric vehicle is connected to it. The maximum power of the electric vehicle can vary depending on the charging mode. For example, the maximum power of the electric vehicle is 6kW when using slow charging, and 60kW when using fast charging.

[0038] As a feasible implementation method, the charging management device can use the charging start time, charging duration, charging demand, and vehicle maximum power as constraints for the intelligent charging scheduling algorithm. The charging time is divided into different time periods according to different electricity costs, and sorted from high to low charging costs. Charging is not performed during the time periods with high charging costs, and charging is performed during the time periods with low charging costs. During the charging time periods, the vehicle can be charged at its maximum power during the time periods with the lowest electricity costs, and at a preset minimum power (e.g., the minimum power to maintain normal operation of the charging pile) when the electricity costs are highest. Other time periods can be adaptively allocated according to the charging demand.

[0039] Based on the aforementioned intelligent charging scheduling algorithm, the charging management device can combine the user-set preset charging range and charging demand with the actual electricity price, and allocate the corresponding power value and schedule the charging time period to the charging pile according to the cost priority principle, so as to ensure that more charging is done when the electricity price is relatively low and less charging is done when the electricity price is relatively high, so as to minimize the user's charging cost.

[0040] As a feasible implementation method, after the charging management device performs intelligent charging scheduling for each charging pile, each charging pile generates the current charging power. Each charging pile can establish a wireless communication connection with the charging management device and send the charging power to the charging management device through the wireless communication connection so that the charging management device can execute the S202 step.

[0041] S202. The charging management device calculates the current total charging power of the charging station based on the charging power of each charging pile.

[0042] For example, with Figure 1 For example, assuming that within the time range of 10:00 to 12:00, the charging power generated by the first charging pile after intelligent charging scheduling is 40kW, and the charging power generated by the second charging pile after intelligent charging scheduling is 42kW, then the current total charging power of the charging station is 82kW.

[0043] S203. The charging management device sends the current total charging power to the billing server.

[0044] It should be noted that the charging management device and the billing server have a pre-established communication connection, and the billing server can receive charging data such as the total charging power sent by the charging management device in real time.

[0045] S204. The billing server receives the current total charging power sent by the charging management device.

[0046] S205. When the current total charging power reaches the target total charging power threshold, the billing server determines the additional fee for the charging station according to the additional charging standard corresponding to the target total charging power threshold.

[0047] This document defines the fee calculated by the billing server involved in this application as the charging fee that the charging station needs to pay to the power grid. This charging fee is divided into two parts: one is the current electricity price, which is calculated according to the time-of-use pricing strategy formulated by the power grid; the other is the additional fee, which is a fee charged in addition to the current electricity price. This additional fee is calculated according to the charging billing method shown in this application.

[0048] As a feasible implementation method, the billing server can divide a day into peak charging periods, off-peak charging periods, and flat charging periods based on the historical charging data of the charging station, and set a preset total charging power threshold for each period in combination with the load limit of the power grid during that period.

[0049] There can be multiple preset total charging power thresholds for each time period, and each preset total charging power threshold can correspond to a different additional charge. The higher the preset total charging power threshold, the higher the additional charge. For example, during peak charging periods, the preset total charging power thresholds can include 50kW, 60kW, etc. The additional charge for exceeding 50kW is 148.79 yuan, and the additional charge for exceeding 60kW is 121.559 yuan.

[0050] In one embodiment, the historical charging data includes at least the start time of charging for each charging pile within a preset time period, the charging power, and the total charging time.

[0051] In one embodiment, the additional charge can be determined based on the charging station's historical charging data. The billing server can determine the additional charge using methods such as... Figure 3 As shown, it includes the following steps:

[0052] S301, The billing server obtains the first historical charging data and the second historical charging data of the charging management device.

[0053] The first historical charging data refers to the charging data of each charging pile when the total charging power is set to not exceed the preset total charging power threshold, and the second historical charging data refers to the historical charging data of each charging pile when the total charging power is not set to not exceed the preset total charging power threshold and the charging cost is controlled to be minimized.

[0054] As a feasible implementation, the charging management device can use a preset total charging power threshold as one of the constraints of the intelligent charging scheduling algorithm. In addition to the constraints of the intelligent charging scheduling algorithm mentioned in step S201 above, when the preset total charging power threshold is added as a constraint, the resulting historical charging data based on the intelligent charging scheduling algorithm is the first historical charging data. Conversely, when the preset total charging power threshold is not added as a constraint, the resulting historical charging data based on the intelligent charging scheduling algorithm is the second historical charging data. The charging management device can send the first and second historical charging data to the billing server.

[0055] S302. The billing server determines the first cost under the preset total charging power threshold constraint based on the first historical charging data.

[0056] As a possible implementation method, the first historical charging data may include multiple sets of data, each set of data may correspond to a cost, and the first cost calculated based on the first historical charging data may be the average of multiple costs.

[0057] S303, The billing server determines the second cost based on the second historical charging data without setting the preset total charging power threshold constraint.

[0058] As a possible implementation method, the second historical charging data may include multiple sets of data, each set of data may correspond to a cost, and the first cost calculated based on the second historical charging data may be the average of multiple costs.

[0059] S304. The billing server calculates the cost difference between the first cost and the second cost.

[0060] S305. The billing server determines the additional charge standard based on the cost difference.

[0061] In one embodiment, step S305 includes: using the sum of the cost difference and a preset charging threshold as the additional charging standard, wherein the preset charging threshold is a fixed value.

[0062] For example, as shown in Table 1 below, assuming that during peak charging periods, without adding the preset total charging power threshold as a constraint, the second cost based on the intelligent charging scheduling algorithm is 475.04 yuan, and with the constraint of adding the total charging power threshold of 50kW, the first cost is 620.83 yuan, with a difference of 145.79 yuan between the two. In this case, the additional charge can be increased by 3 yuan based on the difference between the second cost and the second cost, resulting in 148.79 yuan. Similarly, the additional charge corresponding to each total charging power threshold can be obtained.

[0063]

[0064]

[0065] Table 1

[0066] In one embodiment, the billing server can determine a set of preset total charging power thresholds based on the current total charging power, select the preset total charging power threshold with the smallest difference from the current total charging power from the set of preset total charging power thresholds as the target total charging power threshold, and determine the additional fee of the charging station based on the additional charging standard corresponding to the target total charging power threshold.

[0067] For example, assuming it's currently during peak charging time and the current total charging power is 82kW, the billing server can determine that the preset total charging power threshold set is [50kW, 60kW, 70kW, 80kW]. The difference between 80kW and the current total charging power of 82kW is the smallest. The billing server can further determine that 80kW is the target total charging power threshold and obtain the additional charge of 38.07 yuan corresponding to 80kW as the additional fee for the charging station.

[0068] As can be seen, through the above-described charging billing method, the charging management equipment receives the charging power generated by each charging pile after scheduling based on the intelligent charging scheduling algorithm, calculates the current total charging power of the charging station based on this charging power, and sends the current total charging power to the billing server. The billing server receives the current total charging power and, when it determines that the current total charging power reaches a certain preset total charging power threshold, determines the additional fee for the charging station according to the additional fee standard corresponding to the preset total charging power threshold. Since the additional fee standard is formulated based on historical data obtained after scheduling by the intelligent charging scheduling algorithm, and the additional fee is charged in stages according to different total charging power thresholds, it can effectively ensure that the additional fee is slightly higher than the cost incurred when the total charging power threshold is not used as a constraint condition for the intelligent charging scheduling algorithm. Because the additional fee increases the charging cost, the intelligent charging scheduling algorithm can re-formulate the charging strategy, changing the charging time to other time periods, thereby changing the scheduling method of the intelligent charging scheduling algorithm from the price side. This effectively avoids grid overload during peak charging periods and achieves the peak shaving and valley filling effect of the grid load.

[0069] The method of this application has been described above; the apparatus of this application will be described below.

[0070] See Figure 4 , Figure 4 This is a schematic diagram of the structure of a charging billing device provided in an embodiment of this application, which is applied to a billing server, such as... Figure 4 As shown, the charging metering device 40 includes:

[0071] The first receiving module 401 is used to receive the current total charging power sent by the charging management device.

[0072] Wherein, the current total charging power is the sum of the charging power generated by each charging pile under the charging station after scheduling based on the intelligent charging scheduling algorithm. The intelligent charging scheduling algorithm is an algorithm that minimizes the charging cost while meeting the charging demand within a preset charging time range.

[0073] The determining module 402 is used to determine the additional fee of the charging station according to the additional charging standard corresponding to the target total charging power threshold when the current total charging power reaches the target total charging power threshold.

[0074] The additional fees are charges levied in addition to the current electricity price.

[0075] In one possible design, the determining module 402 is further configured to determine a set of preset total charging power thresholds based on the current total charging power, and select the preset total charging power threshold with the smallest difference from the current total charging power from the set of preset total charging power thresholds as the preset total charging power threshold.

[0076] In one possible design, the additional charge is determined based on the historical charging data of the charging station. The determining module 402 is further configured to: acquire first historical charging data and second historical charging data from the charging management device, wherein the first historical charging data is the charging data of each charging pile when the total charging power is set to not exceed a preset total charging power threshold, and the second historical charging data is the historical charging data of each charging pile when the total charging power is not set to not exceed the preset total charging power threshold and the charging cost is minimized; determine a first cost under the constraint of the preset total charging power threshold based on the first historical charging data, and determine a second cost without the constraint of the preset total charging power threshold based on the second historical charging data; calculate the cost difference between the first cost and the second cost; and determine the additional charge based on the cost difference.

[0077] In one possible design, the historical charging data includes at least the start time of charging for each charging station, the charging power, and the total charging time within a preset time period.

[0078] In one possible design, when the determining module 402 determines the additional charge standard based on the cost difference, it is specifically used to: use the sum of the cost difference and a preset charge threshold as the additional charge standard, wherein the preset charge threshold is a fixed value.

[0079] As can be seen, the charging billing device shown in this application receives the current total charging power sent by the charging management device. When the current total charging power exceeds the target total charging power threshold, it determines the additional fee for the charging station according to the additional charging standard corresponding to the target total charging power threshold. This realizes that additional charges are made according to the pre-set additional charging standard during peak charging periods. It changes the scheduling method of the intelligent charging scheduling algorithm from the price side, effectively avoiding grid overload during peak charging periods and achieving the effect of peak shaving and valley filling of grid load.

[0080] See Figure 5 , Figure 5 This is a schematic diagram of another charging billing device provided in an embodiment of this application. This charging billing device is applied to charging management equipment, such as... Figure 5 As shown, the charging metering device 50 includes:

[0081] The second receiving module 501 is used to receive the charging power generated by each charging pile after scheduling based on the intelligent charging scheduling algorithm. The intelligent charging scheduling algorithm is an algorithm that minimizes the charging cost while meeting the charging demand within a preset charging time range.

[0082] The calculation module 502 is used to calculate the current total charging power of the charging station based on the charging power of each charging pile.

[0083] The sending module 503 is used to send the current total charging power to the billing server so that the billing server can determine the additional fee of the charging station when it detects that the current total charging power exceeds the target total charging power threshold.

[0084] In one possible design, before the second receiving module 501 receives the charging power generated by each charging pile after scheduling based on the intelligent charging scheduling algorithm, it is also used to: receive charging demand data sent by the charging pile, wherein the charging demand data includes at least the charging start time, charging duration, charging demand amount, and vehicle maximum power.

[0085] The charging billing device 50 further includes: a scheduling module ( Figure 5 (Not shown), used to schedule the charging time of the charging pile according to the charging demand data based on the intelligent charging scheduling algorithm, so as to minimize the charging cost of the charging pile.

[0086] As can be seen, the charging billing device shown in this application embodiment receives the charging power generated by each charging pile after scheduling based on the intelligent charging scheduling algorithm, calculates the current total charging power of the charging station based on the charging power of each charging pile, and sends the current total charging power to the billing server. This allows the billing server to determine the additional charge for the charging station when it detects that the current total charging power exceeds the target total charging power threshold. This helps the billing server to charge additional fees according to the pre-defined additional charge standard during peak charging periods. It changes the scheduling method of the intelligent charging scheduling algorithm from the price side, effectively avoiding grid overload during peak charging periods and achieving the effect of peak shaving and valley filling of grid load.

[0087] See Figure 6 , Figure 6 This is a schematic diagram of the structure of a billing server provided in an embodiment of this application. The edge server 60 includes a processor 601, a memory 602, and a transceiver 603. The memory 602 is connected to the processor 601, for example, via a bus.

[0088] Processor 601 is configured to support the billing server 60 in performing the corresponding functions in the methods described in the above method embodiments. Processor 601 may be a central processing unit (CPU), a network processor (NP), a hardware chip, or any combination thereof. The aforementioned hardware chip may be an application-specific integrated circuit (ASIC), a programmable logic device (PLD), or a combination thereof.

[0090] Transceiver 603 is used for data transmission.

[0091] Processor 601 can call the program code to perform the following operations:

[0092] The current total charging power is received from the charging management device. The current total charging power is the sum of the charging power generated by each charging pile under the charging station after scheduling based on the intelligent charging scheduling algorithm. The intelligent charging scheduling algorithm is an algorithm that minimizes the charging cost while meeting the charging demand within a preset charging time range.

[0093] When the current total charging power reaches the target total charging power threshold, the additional fee for the charging station is determined according to the additional charging standard corresponding to the target total charging power threshold. The additional fee is a fee charged in addition to the current electricity price.

[0094] See Figure 7 , Figure 7 This is a schematic diagram of a charging management device provided in an embodiment of this application. The charging management device 70 includes a processor 701, a memory 702, and a transceiver 703. The memory 702 is connected to the processor 701, for example, via a bus.

[0095] The specific structure of the processor 701, memory 702, and transceiver 703 can be referred to the foregoing. Figure 6 The structural descriptions of each component are not elaborated here.

[0096] Processor 701 can call the program code to perform the following operations:

[0097] The system receives the charging power generated by each charging pile after scheduling based on an intelligent charging scheduling algorithm. The intelligent charging scheduling algorithm is an algorithm that minimizes the charging cost while meeting the charging demand within a preset charging time range.
