Description

Technical Field

[0001] The present invention belongs to the field of new energy charging pile management and cloud computing technology, and in particular relates to a charging method for electric vehicle charging piles based on a cloud management platform. Background Art

[0002] The world's pursuit of economic development is becoming more rational, with greater emphasis on the coordinated development of the environment and the economy. As a key measure to address energy shortages, electric vehicles (EVs) will become a mainstream and future trend in the automotive industry for a long time to come. With the increasing number of new energy vehicles, the demand for supporting infrastructure, including charging stations and charging piles, is also increasing. Charging piles are charging devices that provide charging services for electric vehicles. They are mainly divided into floor-standing charging piles and wall-mounted charging piles, and they mainly adopt charging methods based on time, energy consumption, and amount.

[0003] Chinese invention patent application CN202210150308 discloses a method for managing and dispatching power equipment at smart charging stations based on the 5G Internet of Things. It supports users to understand the current vehicle charging information and specific conditions through a mini-program; it can count data such as new users, active users, charging amount, charging positions, and peak conditions at different times, and can also predict and warn of emergencies.

[0004] Most existing charging piles only support time-of-use billing in different time periods, with a single billing method. In addition, their charging power cannot be selected and adjusted according to the actual needs of customers. They cannot meet the personalized needs of customers in two different dimensions of time value and economic consideration based on technical data analysis, resulting in a poor user experience. Summary of the Invention

[0005] In response to the above technical problems, the technical solution proposed in the present invention can perform accurate dynamic billing based on the selection and switching of different identified charging modes, avoiding the defects of the single billing mode of the existing technology, providing more customer choices, and improving user experience.

[0006] In a first aspect of the present invention, a charging method for electric vehicle charging piles based on a cloud management platform is proposed. The method is implemented based on an electronic device and specifically includes the following steps:

[0007] S100: In response to the customer starting the charging pile, providing a user selection interface, the selection interface including at least two optional items;

[0008] S200: In response to receiving a selection from a customer for one of the options on the user selection interface within a preset time period, starting the charging station;

[0009] S300: When charging is completed, charging is performed based on the customer selection;

[0010] The step S100 specifically includes:

[0011] Displaying at least two optional items on the user selection interface, each optional item including a charging mode and an estimated charging end time and an estimated charging end fee corresponding to the charging mode;

[0012] The charging mode includes a local charging mode and a cloud charging mode;

[0013] Specifically, in local charging mode, the charging power of a customer-activated charging station is determined by the actual current output power of multiple local charging stations. In cloud charging mode, the charging power of a customer-activated charging station is determined by the actual output power of multiple charging stations connected to the cloud management platform. In other words, the charging power of an activated charging station in cloud charging mode is no less than that in local charging mode.

[0014] After step S200 and before step S300, the method further includes:

[0015] S210: Displaying the current charging progress and mode switching button on the customer's mobile terminal;

[0016] S220: In response to the customer clicking the mode switching button, displaying at least one switchable target charging mode;

[0017] S230: In response to the first target charging mode selected by the customer, switch the current charging pile to the first target charging mode, and record the time point of switching to the first target charging mode and the current charged amount.

[0018] The step S300 specifically includes: charging based on the customer's selected operations during the entire charging process, the charging time and the charging price under different charging modes.

[0019] More specifically, when the customer chooses to switch the current charging pile from the initially selected charging mode to the first target charging mode, the charging price corresponding to the initially selected charging mode is set to p 1 , the charging price corresponding to the first target charging mode is p 2 The time point of switching to the first target charging mode is t1, the current charged amount is w1, the time point of starting the charging pile is t0, the charging end time point is t2, and the total charged amount is w2.

[0020] The cloud charging price in the cloud charging mode is greater than the local charging price in the local charging mode, and the extent to which the cloud charging price is greater than the local charging price is determined based on the proportion of the time spent executing the cloud charging mode in the entire charging process to the time of the entire charging process.

[0021] Specifically, let the cloud charging price in the cloud charging mode be p c , the local charging price p under the local charging mode l .

[0022] The technical solution of the present invention provides a user selection interface when the customer starts the charging station. The selection interface includes at least two options for the user to select the initial charging mode, and gives the user the option to switch the charging mode again before charging is completed. This allows the user to reasonably select the charging mode according to the actual situation, taking into account the time value and the economic consideration paid. At the same time, the price dynamic change mechanism proposed by the present invention performs accurate dynamic billing based on the selection and switching of different charging modes. This price billing mechanism, based on a combination of technical means, avoids the shortcomings of the single billing model of the existing technology, provides more customer options, and improves the user experience.

[0023] Further advantages of the present invention will be further reflected in detail in the specific embodiments section in conjunction with the drawings of the specification. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments applicable to the present application. Rather, they are merely examples of apparatus and methods applicable to certain aspects of the present application, as detailed in the appended claims.

[0031] In the embodiments of the present application, the term "module" or "unit" refers to a computer program or a part of a computer program that has a predetermined function and works together with other related parts to achieve a predetermined goal, and can be implemented in whole or in part by using software, hardware (such as processing circuits or memories) or a combination thereof. Similarly, a processor (or multiple processors or memories) can be used to implement one or more modules or units. In addition, each module or unit can be part of an overall module or unit that includes the function of the module or unit.

[0032] At the same time, in the specific implementation of this application, if user-related data is involved, when the embodiment of this application is applied to a specific product or technology, user permission or consent must be obtained, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards of relevant countries and regions.

[0033] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically separate entities. That is, these functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0034] See also Figure 1 , Figure 1 The present invention is a schematic diagram of the main process of an electric vehicle charging pile charging method based on a cloud management platform according to an embodiment of the present invention.

[0035] Figure 1 The main steps of the method include S100-S300, and each step is specifically implemented as follows:

[0036] S100: In response to the customer starting the charging pile, providing a user selection interface, the selection interface including at least two optional items;

[0037] S200: In response to receiving a selection from a customer for one of the options on the user selection interface within a preset time period, starting the charging station;

[0038] S300: When charging is completed, billing is performed based on the customer's selection.

[0039] Next, in Figure 1 Based on, combined Figure 2 A schematic diagram of a further preferred embodiment is provided to introduce in detail the specific implementation principles of each step of the above method.

[0040] Regarding step S100, in response to the customer starting the charging pile, providing a user selection interface, a specific implementation method is:

[0041] After the user inserts the charging gun of the charging pile into the car charging port, the charging pile can be started by scanning the corresponding QR code on the charging pile;

[0042] Preferably, the user can start the charging pile by scanning the corresponding QR code on the charging pile through his own mobile terminal, such as a smart phone;

[0043] Before officially starting the charging station, the technical solution of the present invention provides an initial charging mode selection item. That is, after the user's mobile terminal scans the corresponding QR code on the charging station, at least two options are displayed on the selection interface of the mobile terminal. Each option includes a charging mode and an estimated charging end time and estimated charging end fee corresponding to the charging mode. The charging modes include local charging mode and cloud charging mode.

[0044] Next, the process proceeds to step S200 : in response to receiving a selection from a customer for one of the options on the user selection interface within a preset time period, starting the charging station.

[0045] After providing the user with optional options in step S100, if the user selects an initial charging mode (e.g., a local charging mode) within a preset period of time (e.g., 10 seconds), the charging pile is started in the local charging mode;

[0046] If the user does not perform any operation within the preset time period, the charging pile is started according to the default mode (the local charging mode can be set as the default mode);

[0047] In another embodiment, if the user does not perform any operation within a preset time period, the charging pile is started according to a historical mode; the historical mode is the charging mode most recently selected by the current charging customer recorded by the cloud management platform.

[0048] As one of the advantages of the technical solution of the present invention, the charging mode includes a local charging mode and a cloud charging mode;

[0049] In the local charging mode, the charging power of the charging pile started by the customer is determined by the actual output power of multiple local charging piles.

[0050] In the cloud charging mode, the charging power of the charging pile started by the customer is determined by the actual output power of multiple charging piles connected to the cloud management platform.

[0051] In local charging mode, the charging power of the charging pile started by the customer is determined by the actual output power of multiple local charging piles (for example, multiple adjacent charging piles currently installed in the same area). In other words, the dispatchable charging power is limited to the local power supply energy. Therefore, the upper limit of the charging power of the charging pile in local charging mode is relatively low.

[0052] In the cloud charging mode, the charging power of the charging pile started by the customer is determined by the actual output power of multiple charging piles connected to the cloud management platform. That is, at this time, the cloud can be based on all the currently available energy of the entire power grid (or a local dispatchable power grid, for example, the entire industrial park, the entire region), so that the charging power of each charging pile in the cloud charging mode has a higher upper limit.

[0053] That is to say, the energy acquisition priority (power scheduling priority) of the charging pile in the cloud charging mode is greater than the energy acquisition priority of the charging pile in the local charging mode. In other words, in an embodiment of the present invention, the charging power of the started charging pile in the cloud charging mode is not lower than the charging power in the local charging mode.

[0054] When the customer's charging vehicle supports higher charging power, higher charging power means shorter charging waiting time, but the economic cost may be higher.

[0055] Specifically, the cloud charging price in the cloud charging mode is greater than the local charging price in the local charging mode.

[0056] In actual applications, the current personal needs of customers who do not need to charge may be different. Some customers may not be in a hurry, so they are willing to pay more waiting time to choose normal power or even give up charging power; some customers have a higher value on time and are willing to pay a greater economic price in exchange for a shorter waiting time.

[0057] Therefore, in an embodiment of the present invention, at least two optional items are displayed on the user selection interface, each optional item including a charging mode and an estimated charging end time and an estimated charging end fee corresponding to the charging mode, for the customer to select.

[0058] If the customer does not change the charging mode after the initial selection, the application directly proceeds to step S300: at the end of charging, billing is performed based on the customer's selection.

[0059] However, the above options still lack flexibility. In practice, customer needs may change. A customer may initially be willing to wait longer, but after a while may want to shorten the wait time. Or, a customer may initially be unwilling to wait longer, but after considering the price, may want to lower the price, given that they have more time.

[0060] At this time, in response to the above problems, the embodiments of the present application are further improved as follows, see Figure 2 .

[0061] A charging method for electric vehicle charging piles based on a cloud management platform, the method comprising the following steps:

[0062] S100: In response to the customer starting the charging pile, providing a user selection interface, the selection interface including at least two optional items;

[0063] Displaying at least two optional items on the user selection interface, each optional item including a charging mode and an estimated charging end time and an estimated charging end fee corresponding to the charging mode;

[0064] S200: In response to receiving a selection from a customer for one of the options on the user selection interface within a preset time period, starting the charging station;

[0065] S210: Displaying the current charging progress and mode switching button on the customer's mobile terminal;

[0066] S220: In response to the customer clicking the mode switching button, displaying at least one switchable target charging mode;

[0067] S230: In response to the first target charging mode selected by the customer, switching the current charging pile to the first target charging mode, and recording the time point of switching to the first target charging mode and the current charged amount;

[0068] Step S300: Billing is performed based on the customer's selected operations during the entire charging process, the charging time under different charging modes, and the charging price.

[0069] It can be seen that through the above improvements, the technical solution of the present invention provides a user selection interface when the customer starts the charging pile. The selection interface includes at least two options for the user to select the initial charging mode, and gives the user the option of switching the charging mode again before the end of charging, so that the user can reasonably select the charging mode according to the actual situation, taking into account the time value and the economic consideration paid.

[0070] The above-mentioned dynamic improvement and selection mechanism of the present invention can realize a dynamic billing mechanism automatically through a computer program.

[0071] First, in terms of price, the cloud charging price in the cloud charging mode is greater than the local charging price in the local charging mode, and the extent to which the cloud charging price is greater than the local charging price is determined based on the proportion of the time spent executing the cloud charging mode in the entire charging process to the time of the entire charging process.

[0072] As a preference, the local charging price p in the local charging mode can be set first. l , and then, the cloud charging price p in the cloud charging mode c It is determined by a dynamic change mechanism. Specifically:

[0073] p c and p l The following conditions must be met:

[0074] p c =(1+Δ)·p l

[0075]

[0076] Among them, t a ll is the length of the entire charging period, t c is the duration of executing cloud charging mode, t c The length of time to execute local charging mode.

[0077] It can be seen that in the above dynamic change mechanism, although the cloud charging price p c Always higher than the local charging price p l However, in order to encourage customers to use the cloud charging mode to improve resource utilization efficiency (because it relatively reduces the charging waiting time), the longer the customer uses the cloud charging mode during the entire process, the lower the price;

[0078] For example, if the customer chooses the local charging mode at the beginning, when the charging time is halfway Then I remembered to switch to cloud charging mode. However, if the customer chooses the cloud charging mode from the beginning and continues until the charging is completed, that is, t c =t all , t l =0; then Δ = 0.5; p c =1.5p l .

[0079] At the same time, in order to further improve the tracking of this pricing mechanism with technical detection data, as another preferred technical improvement, when the customer chooses to switch the current charging pile from the initially selected charging mode to the first target charging mode,

[0080] Assume that the charging price corresponding to the initially selected charging mode is p 1 (Unit: xx yuan / kWh or xx yuan / kWh), the charging price corresponding to the first target charging mode is p 2 The time point of switching to the first target charging mode is t1, the current charged amount is w1 (unit, degree or kilowatt-hour, kwh), the time point of starting the charging pile is t0, the charging end time point is t2, and the total charged amount is w2 (unit, degree or kilowatt-hour, kwh);

[0081] Then the step S300 specifically includes:

[0082] when When the billing amount

[0083] when When the billing amount

[0084] The above-mentioned as well as At the same time, in order to provide the globally optimal resource management solution for each charging pile connected to the cloud management platform as soon as possible, the above-mentioned pricing mechanism actually encourages users to switch modes as soon as possible (at least before the charging progress is halfway), if they want to, so as to avoid the subsequent switching bringing additional scheduling costs to resource management.

[0085] Theoretically, after a user activates a charging station and before charging is complete, they can adjust the charging mode multiple times. However, frequent mode switching can impact the power network and increase scheduling costs for the cloud management platform. Therefore, in an embodiment of the present invention, the user is given only one opportunity to adjust the charging mode after activating the charging station and before charging is complete, to avoid frequent impacts on the entire scheduling network.

[0086] based on Figure 1-Figure 2 From the introduction of the embodiments and the explanation of the working principles above, it can be seen that, compared with the existing technology, the price dynamic change mechanism proposed in the present invention performs accurate dynamic billing based on the selection and switching of different charging modes identified. This price billing mechanism is based on a combination of technical means, which avoids the defects of the single billing model of the existing technology, provides more customer choices, and improves the user experience.

[0087] After introducing the method embodiment, see Figure 3-Figure 4 , continue to introduce the system or device embodiments of the present invention.

The multiple charging piles 1-N include multiple adjacent charging piles located in a local area, and multiple other charging piles located in other areas that belong to the same cloud management platform (e.g., a local dispatchable power grid, such as an entire industrial park, or other charging piles in the entire region).

[0090] The system comprises:

[0095] The selection operation of the customer during the entire charging process includes an initial mode selection operation when starting the charging pile and a charging mode switching selection operation before charging is completed.

[0096] After starting the charging pile and before charging is completed, the current charging progress and mode switching button are displayed on the customer's mobile terminal;

[0097] In response to the customer clicking the mode switching button, displaying at least one switchable target charging mode;

[0098] In response to the first target charging mode selected by the customer, the current charging pile is switched to the first target charging mode, and the time point of switching to the first target charging mode and the current charged amount are recorded.

[0099] The cloud charging price in the cloud charging mode is p c , the local charging price p under the local charging mode l ;

[0102]

[0103] Among them, t all is the length of the entire charging period, t c is the duration of executing cloud charging mode, t c The length of time to execute local charging mode.
