Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a charging system, charging management method and device. Background Technology

[0002] With the explosive growth of electric vehicles and other electric equipment, the demand for charging stations has also increased. However, the reserved power capacity of charging stations is currently limited. Once the number of charging stations reaches the installation limit, no more can be added, failing to meet users' demand for additional charging stations. Therefore, how to meet users' demand for additional charging stations after the installation limit is reached, given the limited reserved power capacity, is an urgent problem that needs to be solved. Summary of the Invention

[0003] To address the aforementioned problems, embodiments of this application provide a charging system, charging management method, and apparatus. This application connects multiple charging piles in parallel via a shared power line. When the number of charging piles reaches the installation limit, a charging strategy is determined to solve the charging problem of multiple charging piles when the reserved power capacity is limited.

[0004] Therefore, the following technical solutions are adopted in the embodiments of this application:

[0005] In a first aspect, this application provides a charging system comprising: a power mainline; multiple charging piles connected in parallel to the power mainline for power supply; and a management module configured to determine the power limit of the multiple charging piles and the total power demand of the charging piles performing charging operations; and when the total power demand exceeds the power limit, to determine a charging strategy based at least on the power limit to manage the charging operations of the multiple charging piles; wherein the charging strategy includes determining the charging sequence of the charging piles performing charging operations, or determining the charging duration, or determining the charging amount, or determining the charging power.

[0006] In this embodiment, the charging strategy includes determining the charging order of the charging piles based on the order in which charging requests are received or based on the priority of each charging pile; or taking turns charging the charging piles based on a preset charging time period or a preset charging amount; or simultaneously charging one or more charging piles at a preset charging power. When multiple charging piles are charging simultaneously, and the total demand power exceeds the power limit, a charging strategy is determined at least within the power limit to manage the charging operations of the multiple charging piles, thereby solving the charging problem when the total demand power of multiple charging piles exceeds the allowable power capacity. Furthermore, by using a shared power line for the installation and wiring of the charging piles, when additional charging piles are needed, the charging cables of the newly added charging piles are directly connected to the shared power line, eliminating the need for repeated installation work and reducing the installation cost of the charging piles.

[0007] In one implementation, the power limit of the plurality of charging piles is determined based on a pre-set power.

[0008] In this embodiment, the method for pre-determining the power limit may include the rated power of the household electricity meter or the available power of the remaining power capacity of the power system. By pre-determining the power limit, the power usage of multiple charging piles in the charging system of this embodiment can be controlled, thereby completing the charging operation of the charging system while ensuring electrical safety.

[0009] In one implementation, the power limit is determined based on the power of other loads connected to the power main.

[0010] In this embodiment, since the charging system is a complete system, it includes not only charging piles but also other loads, such as lighting devices. Because the connection status of these other loads changes in real time, their power consumption also changes in real time. Therefore, this embodiment considers the situation where other loads are connected to the charging system. The power limit is determined based on the power of these other loads connected to the main power line, allowing for real-time adjustments to the power limit, thus improving the utilization rate of available power and the charging efficiency of the charging system.

[0011] In one embodiment, each of the plurality of charging piles is equipped with a communication module to enable communication between the management module and each charging pile.

[0012] In this embodiment, a communication module is configured to establish a communication connection between the management module and each charging pile, resolving the information exchange issue between the management module and the charging piles. This communication module can transmit charging strategies and obtain real-time information on the charging pile's operational status, including whether any devices are connected to the charging pile and whether any charging pile has completed its charging operation, allowing for adjustments to the charging strategy. This enables the charging system in this embodiment to establish communication connections and network the charging piles currently performing charging operations.

[0013] In one embodiment, the management module is further configured to: in response to the number of charging piles performing charging operations being greater than or equal to a preset threshold, send activation and networking instructions to the communication modules in the charging piles performing charging operations, and network the charging piles performing charging operations with each other, wherein the network connection between the charging piles performing charging operations refers to the communication network connection between the charging piles performing charging operations.

[0014] In this embodiment, based on the specific circumstances of the multiple charging piles in the charging system, different networking operations are adopted according to the number of charging piles currently performing charging operations by setting preset thresholds. For example, when the number of charging piles currently performing charging operations is less than the preset threshold, the total power demand of the charging system is less than the power limit, and charging operations can proceed directly without inter-pile networking. When the number of charging piles currently performing charging operations is greater than or equal to the preset threshold, the total power demand of the charging system is greater than or equal to the power limit, and charging operations need to be performed using a charging strategy. This involves networking the charging piles currently performing charging operations to transmit the charging strategy. This embodiment further limits the use of charging strategies for charging operations by setting preset thresholds. When the number of charging piles currently performing charging operations is less than the preset threshold, charging operations can proceed directly, improving charging efficiency.

[0015] In one embodiment, the management module is further configured to acquire charging pile operating status information of the plurality of charging piles, the charging pile operating status information including the power consumption of the charging pile and whether the charging pile is in charging operation state; and to determine the charging strategy based on the power limit and the charging pile operating status information of the plurality of charging piles.

[0016] In this embodiment, when a device to be charged is connected to a charging pile, or when a charging pile completes a charging operation, the charging pile working status information of the multiple charging piles will change. The charging strategy is also related to the charging pile working status information of the multiple charging piles. By obtaining the charging pile working status information of the multiple charging piles, this embodiment enables the charging strategy to be adjusted in a timely manner, thereby improving the charging system's charging efficiency and response performance.

[0017] In one embodiment, the management module is located at each of the plurality of charging piles.

[0018] In this embodiment, the management module is set at each of the multiple charging piles. Compared with a separate external management module, this avoids the need for wiring and installation facilities, reducing the complexity of the system. At the same time, when the management module in use fails, the management module of another charging pile can be selected to perform the charging operation, ensuring that the charging system can continue to operate smoothly when the management module fails.

[0019] In one implementation, the management module is further configured to select a main charging pile from the plurality of charging piles, the main charging pile being used to determine a charging strategy.

[0020] In this embodiment, by further dividing the work of determining the charging strategy, the workload of the management module can be reduced, and the charging efficiency and response performance of the charging system can be improved. For example, when there is a separate peripheral management module, the main charging pile determines the charging strategy, which can reduce the workload of the management module and improve its response performance; when the management module is set at each of the multiple charging piles, the management module of the main charging pile can determine the charging strategy, and the management modules of other charging piles do not need to perform the work of determining the charging strategy, thereby reducing the workload of the management module.

[0021] In one implementation, the management module is further configured to receive signal data from the terminal device; the determination of the charging strategy is also related to the signal data from the terminal device.

[0022] In this implementation, the signal data from the terminal device includes processing operation information for the corresponding charging pile, such as fault handling, charging time adjustment, and charging pile priority adjustment. When determining the charging strategy, the content requirements of the signal data from the terminal device must also be met. Users can influence the charging operation of the charging system through their terminal devices, satisfying their charging requirements and improving the user experience.

[0023] In one embodiment, the charging strategy includes: controlling the charging piles to perform charging operations according to the order in which charging requests are received; controlling the corresponding charging piles to perform charging operations within a preset time period; controlling each charging pile to perform charging operations based on the priority of each charging pile; controlling each charging pile to perform charging operations in turn based on the preset power capacity of each charging pile; controlling multiple charging piles to perform charging operations simultaneously; and controlling multiple charging piles to perform charging operations in turn based on the charging pile numbers of the multiple charging piles that are currently performing charging operations, one or more of the following.

[0024] In this embodiment, by selecting or combining different charging strategies, the charging strategy of the charging system is determined, thereby meeting the charging operation requirements of the charging system.

[0025] Secondly, this application provides a charging management method, including: determining the power limit of multiple charging piles and the total power demand of the charging piles performing charging operations; when the total power demand is greater than the power limit, determining a charging strategy based at least on the power limit to manage the charging operations of the multiple charging piles; wherein the charging strategy includes determining the charging sequence of the charging piles performing charging operations, or determining the charging duration, or determining the charging amount, or determining the charging power.

[0026] In one implementation, the power limit of the plurality of charging piles is determined based on a pre-set power.

[0027] In one implementation, the power limit is determined based on the power of other loads connected to the power main.

[0028] In one embodiment, before determining the charging strategy based at least on the power limit, the method further includes: when the number of charging piles performing charging operations is greater than or equal to a preset threshold, sending an activation and networking command to the communication module in the charging piles performing charging operations to form an inter-pile network for the charging piles performing charging operations, wherein the inter-pile network refers to the communication network connection between the charging piles performing charging operations.

[0029] In one embodiment, before determining the charging strategy at least according to the power limit, the method further includes: selecting a main charging station from the plurality of charging stations, the main charging station being used to determine the charging strategy.

[0030] In one embodiment, the charging management further includes: acquiring the charging pile operating status information of the plurality of charging piles, the charging pile operating status information including the power consumption of the charging pile and whether the charging pile is in charging operation state; and determining the charging strategy based on the power limit and the charging pile operating status information of the plurality of charging piles.

[0031] In one embodiment, the charging management further includes: receiving signal data from the terminal device; and the determination of the charging strategy is also related to the signal data from the terminal device.

[0032] In one embodiment, the charging strategy includes: controlling the charging piles to perform charging operations according to the order in which charging requests are received; controlling the corresponding charging piles to perform charging operations within a preset time period; controlling each charging pile to perform charging operations based on the priority of each charging pile; controlling each charging pile to perform charging operations in turn based on the preset power capacity of each charging pile; controlling multiple charging piles to perform charging operations simultaneously; and controlling multiple charging piles to perform charging operations in turn based on the charging pile numbers of the multiple charging piles that are currently performing charging operations, one or more of the following.

[0033] Thirdly, this application provides a charging management device, including: a transceiver unit for establishing a communication connection between the charging management device and the charging piles; a processing unit for determining power limits of multiple charging piles and the total power demand of the charging piles performing charging operations; and when the total power demand exceeds the power limits, determining a charging strategy based at least on the power limits to manage the charging operations of the multiple charging piles; wherein the charging strategy includes determining the charging sequence of the charging piles performing charging operations, or determining the charging duration, or determining the charging amount, or determining the charging power.

[0034] In one embodiment, the processing unit is specifically configured to determine the power limit of the plurality of charging piles based on a preset power.

[0035] In one implementation, the processing unit is specifically configured to determine the power limit based on the power of other loads connected to the power mainline.

[0036] In one embodiment, the transceiver unit is specifically used to send activation and networking instructions to the communication modules of the charging piles performing the charging operation when the number of charging piles performing the charging operation is greater than or equal to a preset threshold, so as to form an inter-pile network between the charging piles performing the charging operation. The inter-pile network refers to the communication network connection between the charging piles performing the charging operation.

[0037] In one embodiment, the processing unit is specifically used to select a main charging pile from the plurality of charging piles, the main charging pile being used to determine a charging strategy.

[0039] In one embodiment, the processing unit is specifically configured to receive signal data from the terminal device; and the determination of the charging strategy is also related to the signal data from the terminal device.

[0040] In one embodiment, the charging strategy includes: controlling the charging piles to perform charging operations according to the order in which charging requests are received; controlling the corresponding charging piles to perform charging operations within a preset time period; controlling each charging pile to perform charging operations based on the priority of each charging pile; controlling each charging pile to perform charging operations in turn based on the preset power capacity of each charging pile; controlling multiple charging piles to perform charging operations simultaneously; and controlling multiple charging piles to perform charging operations in turn based on the charging pile numbers of the multiple charging piles that are currently performing charging operations, one or more of the following.

[0054] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0055] In this article, the term "and / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three cases: A exists alone, A and B exist simultaneously, and B exists alone. The symbol " / " in this article indicates that the related objects have an "or" relationship; for example, A / B means A or B.

[0056] The terms "first" and "second," etc., used in the specification and claims herein are used to distinguish different objects, not to describe a specific order of objects. For example, "first response message" and "second response message," etc., are used to distinguish different response messages, not to describe a specific order of response messages.

[0057] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0058] In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more, for example, multiple processing units means two or more processing units, multiple elements means two or more elements, etc.

[0059] To meet the needs of users who require additional charging stations, one solution is to connect the new charging station using a separate wiring method.

[0060] The above solutions require re-distributing power in the power distribution room. Given the limited reserved power capacity of the charging stations, only a limited number of charging stations can be installed. Once the installation limit is reached, no more charging stations can be added, failing to meet users' needs for additional charging stations. When a new charging station needs to be connected, the separate wiring method requires re-distributing power in the power distribution room and installing electricity meters. Each time a charging station is added, the installation work needs to be repeated, increasing the installation cost of the charging stations.

[0061] Therefore, this application proposes another solution: a charging system comprising: a power mainline; multiple charging piles connected in parallel to the power mainline for power supply; a management module for determining power limits for the multiple charging piles; and determining a charging strategy based at least on the power limits to manage the charging operations of the multiple charging piles. In this embodiment, when multiple charging piles are charging simultaneously, a charging strategy is determined at least within the power limit requirements to manage the charging operations of the multiple charging piles, thereby solving the charging problem when the total power demand of multiple charging piles exceeds the allowable power capacity.

[0062] Figure 1 This is a schematic diagram of a charging system provided in an embodiment of this application. Figure 1 As shown, the system includes a main power line 100, multiple charging piles, and a management module 300. The main power line 100 is a bus that provides input power to the multiple charging piles, which are connected in parallel to the bus for power. The main power line 100 is the DC bus for the charging piles, not a mains power transmission cable. In one embodiment, the main power line 100 loops around all parking spaces to facilitate the connection of any additional charging piles added later. The multiple charging piles may include, for example, a power main line 100... Figure 1 The charging piles 210 and 220 are shown. For each additional charging pile, its charging cable needs to be connected in parallel to the main power line 100. The management module 300 determines the power limit of the multiple charging piles. Under the constraint of this power limit, the management module 300 manages the multiple charging piles to perform charging operations. The networking method between the management module 300 and the multiple charging piles can be wireless or wired.

[0063] In one embodiment, the number of power mains 100 can be selected based on power limits. When the power limit is high, a larger number of power mains 100 can be selected. The connection relationship between the power mains 100 and multiple charging piles in the system architecture with multiple power mains 100 is the same as that in the system architecture with one power main 100. The power limit of the multiple charging piles on multiple power mains 100 is the sum of the power of the multiple charging piles on multiple power mains 100, and the multiple charging piles are connected in parallel to multiple buses for power supply. This embodiment uses one power main 100 as an example for illustration.

[0064] In one embodiment, a communication module may be installed inside the charging pile to facilitate inter-pile ad-hoc network transmission among multiple charging piles. Through this inter-pile ad-hoc network transmission, the communication module can obtain the charging pile's operational status information at a given time, including the charging pile's power consumption and whether the charging pile is in operation. The charging pile sends this operational status information, and the management module 300 receives it, determines and sends a charging strategy, which is then received and executed by the multiple charging piles performing the charging operation.

[0065] In another feasible embodiment, the charging piles may not have an internal communication module. Instead, a management module 300 can be used to network and transmit data among multiple charging piles. The management module 300 can obtain the operating status information of charging piles currently performing charging operations, including the power consumption of the charging piles and whether the charging piles are in a charging operation state. Based on the charging pile operating status information, the management module 300 determines and sends a charging strategy, which is then received and executed by the multiple charging piles performing charging operations.

[0066] Figure 2 This is a schematic diagram of another charging system provided in an embodiment of this application. For example... Figure 2 As shown, the system includes a main power line 100 and multiple charging piles. The main power line 100 is connected to multiple charging piles, which may include, for example, […]. Figure 2 The charging piles 210 and 220 are shown. The main power line 100 is a bus that provides input power to multiple charging piles. For each additional charging pile, its charging cable needs to be connected in parallel to the main power line 100. Power limits for the multiple charging piles are determined. Under these limits, inter-pile signal transmission is achieved through a self-organizing network, and a charging strategy is used to control the charging operations of the multiple charging piles.

[0067] In one embodiment, charging operations are achieved by networking charging piles that are currently performing charging operations. Each charging pile has a communication module and an internal management module. The internal management module refers to the presence of a management module within the charging pile, and is not a limiting description of its location and function. Communication is established through the charging pile's communication module, which can obtain the operating status information of the charging piles performing charging operations at a given time, including the charging pile's power consumption and whether the charging pile is in a charging operation state. After obtaining the operating status information of the charging piles performing charging operations, the communication modules of the multiple charging piles performing charging operations form an inter-pile self-organizing network. For example, based on the charging pile operating status information, the internal management module of the charging pile selects a master charging pile from the multiple charging piles performing charging operations, or it can select a master charging pile from all charging piles. The master charging pile determines and sends a charging strategy, which is received and executed by all the multiple charging piles performing charging operations. The inter-pile self-organizing network enables the transmission of the charging strategy. Meanwhile, the communication module can monitor the working status information of all or a preset number of charging piles in real time, update the working status information of the charging piles in real time, and then update the charging strategy in real time.

[0068] In another feasible embodiment, charging is not achieved by creating an inter-pile self-organizing network of charging piles currently performing charging operations. Each charging pile has a communication module and an internal management module. When a charging device with charging needs connects to the charging pile, the communication module connects to a preset number or all charging piles. This communication module can obtain the operating status information of the charging piles currently performing charging operations at a given time, including the power consumption of the charging pile and whether the charging pile is in a charging operation state. Based on the charging pile operating status information, the internal management module of the charging pile selects a master charging pile from among the multiple charging piles performing charging operations, or it can select a master charging pile from all charging piles. The master charging pile determines and sends a charging strategy, which is then received and executed by all the multiple charging piles performing charging operations.

[0069] The charging pile in this embodiment has an internal management module. When the management module of the main charging pile malfunctions and cannot determine and send the charging strategy, another charging pile can be selected as the main charging pile to complete the determination and sending of the charging strategy, thereby ensuring the charging operation. In one embodiment, during the selection of the main charging pile, multiple charging piles can be troubleshooted first to eliminate charging piles whose internal management modules are malfunctioning.

[0070] Figure 3 This is a schematic diagram of the architecture of a charging system provided in an embodiment of this application. Figure 3As shown, this architecture includes a main power line 100 and multiple charging piles. Each charging pile is equipped with a communication module and an internal management module. The main power line 100 is connected to multiple charging piles, which may include, for example, […]. Figure 3 The charging piles 210 and 220 are shown. For example, as shown... Figure 3 As shown, charging pile 210 includes a communication module 211 and an internal management module 212, while charging pile 220 includes a communication module 221 and an internal management module 222. The communication modules enable communication connections between multiple charging piles and allow for real-time monitoring of the charging operation status and transmission of charging strategies for all charging piles. The internal management module selects a master charging pile from among the multiple charging piles performing charging operations, or from all charging piles, based on the charging pile's operating status information. The master charging pile's internal management module determines and sends the charging strategy, and the internal management modules of all the multiple charging piles performing charging operations receive and execute this charging strategy.

[0071] In one embodiment, charging operations are achieved by networking the charging piles that are currently undergoing charging. In one embodiment, the self-organizing network between charging piles with communication modules can be a wireless connection, such as Bluetooth, Wireless Fidelity (Wi-Fi), Ethernet, or Low-Power Wide-Area Network (LPWAN); or it can be a wired connection, such as connecting multiple charging piles through cabling, such as fiber optic cables or electrical wires.

[0072] In this embodiment of the application, by determining the power limit of multiple charging piles connected to the main power line 100, the management module 300 controls and manages the charging operation of the multiple charging piles under the limitation of the power limit.

[0073] In another feasible embodiment, the main power line 100 is connected to a household electricity meter, and the rated power of the household electricity meter is lower than the available power of the remaining power capacity of the power system. Based on the rated power of the household electricity meter, the power limits of multiple charging piles connected to the main power line 100 are preset. The rated power of the household electricity meter is preset in the management module 300 or the management module 212 inside the multiple charging piles using program instructions.

[0074] In another feasible embodiment, if the main power line 100 is not connected to a household electricity meter, or if it is connected to a household electricity meter but the rated power of the meter is higher than the available power of the remaining power capacity reserved by the power system for the charging system, then a power limit for the main power line 100 is preset based on the available power of the remaining power capacity of the power system. The available power of the remaining power capacity of the power system is preset in the management module 300 or the management module 212 within the multiple charging piles using program instructions.

[0075] In another feasible embodiment, the power limit is determined based on the power of other loads connected to the main power line. When other loads, such as lighting devices, are connected to the charging system, and this changes in real time, the power available to multiple charging piles in the charging system will also change in real time. For example, when other loads are connected, the total power allowed by the power system minus the power of the other loads is the power limit of the charging system for each charging pile. Based on changes in available power and a pre-set strategy, the power limits for multiple charging piles need to be dynamically set to improve the utilization rate of the remaining power capacity reserved for the charging system by the power system. The pre-set strategy includes: dynamically setting the power limits for multiple charging piles based on a fixed percentage of the power available to multiple charging piles after changes in the connected load of the charging system; and dynamically setting the power limits for multiple charging piles based on a fixed difference in the power available to multiple charging piles after changes in the connected load of the power system.

[0076] In another feasible embodiment, when the rated power of the household electricity meter is lower than the available power of the remaining power capacity of the power system by a predetermined threshold, such as less than half, multiple user meters can be connected by deploying multiple main power lines 100 instead of the single main power line 100 in the previous scheme. Multiple charging piles can then be connected in parallel to these multiple main power lines 100. This ensures that the power limit is the total power of the household electricity meters connected to the multiple main power lines 100, thereby improving the utilization rate of the available power of the remaining power capacity of the power system, increasing charging efficiency, and enhancing the user experience. Alternatively, replacing the meter with a higher-power one can also improve the utilization rate of the available power of the remaining power capacity of the power system.

[0077] In one embodiment, multiple charging piles are connected to the main power line 100 via a non-disconnecting T-connection, forming a multi-pile shared main power line architecture, allowing multiple charging piles to be connected with a single wiring connection. For example, the non-disconnecting node of the main power line 100 uses a T-connection terminal, such as a non-disconnecting wiring method, to connect multiple charging piles. The non-disconnecting wiring method includes a non-disconnecting connector.

[0078] Figure 4 This is a flowchart illustrating a charging pile charging management method provided in an embodiment of this application. Figure 4 As shown, the specific process of the charging pile charging management method is as follows:

[0079] Step S401: Determine the power limit.

[0080] In one embodiment, the power limit is used to restrict the total power of the charging pile performing the charging operation to prevent damage to the power facilities from exceeding the maximum allowable power.

[0081] In one embodiment, the power limit can be the power limit of multiple charging piles connected to the main power line 100, that is, the power limit of the total power of charging piles operating simultaneously. Methods for determining the power limit include: pre-setting a power limit based on the rated power of the household electricity meter; pre-setting a power limit based on the available power of the remaining power capacity of the power system; and dynamically determining the power limit based on a pre-set strategy. The specific details of the methods for determining the power limit are not elaborated here.

[0082] In one embodiment, the power limit can be preset and stored in the management module inside the charging pile.

[0083] Step S402: Obtain the charging pile's working status information.

[0084] In one embodiment, the operating status information of charging piles can be obtained by establishing communication connections with all or a preset number of charging piles. For example, when there are charging piles needed for emergency situations or special requirements, communication connections can be established with the preset number of charging piles. The operating status information of the charging piles includes the power consumption of the charging piles and whether the charging piles are in a charging operation state.

[0085] In one embodiment, a preset number or all charging piles are connected via a communication module. This communication module can obtain the operational status information of charging piles currently performing charging operations, including the number of charging piles and their serial numbers. This communication connection enables real-time monitoring of the charging operation status of all charging piles, real-time updates of the charging pile operational status information, and consequently, real-time updates to the charging strategy managing multiple charging piles.

[0086] In another feasible embodiment, the management module 300 obtains the working status information of the charging pile that is charging at a certain moment through a wired or wireless connection, and then updates the charging strategy in real time.

[0087] Step S403: Select the main charging station.

[0088] In one embodiment, a self-organizing network, also known as an inter-pile network, can be established among the charging piles currently performing charging operations. Based on the charging pile's operational status information, a master charging pile can be selected from multiple charging piles currently performing charging operations. Alternatively, the charging pile can be selected from all or a preset number of charging piles using a preset method, including random selection or selection by charging pile number.

[0089] In one embodiment, based on the charging pile's operational status information, a self-organizing network is established between multiple charging piles currently charging. Alternatively, the communication connections of all or a preset number of charging piles can be utilized. The internal management module of each charging pile can select a master charging pile from among the multiple charging piles performing charging operations, or it can select a master charging pile from all charging piles. Simultaneously, the self-organizing network enables the transmission of charging strategies. Compared to communication connections, establishing a self-organizing network between multiple charging piles currently charging reduces the number of charging piles receiving charging strategies, thus improving the transmission efficiency of charging strategies.

[0090] In one embodiment, at least one backup main charging pile can be selected as the main charging pile to complete the determination and transmission of the charging strategy when the management module inside the main charging pile fails and cannot determine and send the charging strategy, so as to ensure the charging operation can proceed.

[0091] In one embodiment, based on the charging pile's operating status information, the management module 300 or the internal management module of the charging pile determines the number of charging piles currently performing charging operations. When the number of charging piles currently performing charging operations is greater than or equal to a preset threshold, such as 1 or 10, the sum of the power of the charging piles currently performing charging operations in the charging pile operating status information is the total required power. If it is greater than or equal to the power limit, inter-pile self-organizing network or selection of a master charging pile is required. The management module 300 or the internal management module of the charging pile sets up inter-pile networking for the charging piles currently performing charging operations. In one embodiment, a master charging pile is selected to determine the charging strategy, and the inter-pile self-organizing network transmits the charging strategy used to manage the charging operations of multiple charging piles.

[0092] In one embodiment, the inter-pile networking process includes:

[0093] Step 1: A preset threshold for the number of charging piles is pre-set in the charging pile management module 212 or the peripheral device management module 300. For example, the preset threshold is the integer part of the power limit divided by the power consumption of a single charging pile, wherein when the power of the charging piles is different, the power consumption of a single charging pile is the power consumption of the charging pile with the highest power consumption.

[0094] Step 2: Monitor the working status information of multiple charging piles via wired or wireless means.

[0095] Step 3: Determine the number of charging piles to be charged based on the charging pile's working status information.

[0096] Step 4: When the number of charging piles exceeds the preset threshold for the number of charging piles, the management module 212 of the charging piles or the management module 300 of the peripheral devices sends activation and networking instructions to the communication module of the charging piles performing the charging operation.

[0097] Step 5: The communication modules of the charging piles performing the charging operation establish inter-pile networking, connecting the charging piles performing the charging operation to a communication network. Here, inter-pile networking refers to the communication network connection established between the charging piles performing the charging operation.

[0098] In one embodiment, when the number of charging piles in operation in the charging pile working status information is less than or equal to a preset threshold, such as 1 or 10, the total power demand of the charging piles in operation in the charging pile working status information is less than the power limit. There is no need for self-organizing a network between piles or selecting a main charging pile. When there is a device to be charged connected to the charging pile, the charging operation can be carried out directly according to the actual demand.

[0099] In one embodiment, the method for selecting the main charging pile includes: determining the main charging pile based on the charging pile number of multiple charging piles that are currently charging; and determining the main charging pile based on the order in which charging requests are received.

[0100] Step S404: The main charging station determines the charging strategy.

[0101] In one embodiment, based on the charging pile's operating status information or power limit, the internal management module of the main charging pile determines the charging strategy and sends the charging strategy through the main charging pile's communication module.

[0102] In one embodiment, charging strategies can be sent and received through the communication module of the charging pile, or through the management module 300.

[0103] In one embodiment, under the condition of meeting the power limit requirement, the main charging pile determines a charging strategy to perform charging operations based on the charging pile's operating status information or the power limit. For example, when the number of charging piles currently performing charging operations in the charging pile's operating status information exceeds a preset threshold (e.g., 1, 10), or when the total power of the charging piles currently performing charging operations exceeds the power limit. Alternatively, without determining whether the power exceeds the preset threshold or the power limit, the main charging pile can determine a charging strategy to perform charging operations based on the charging pile's operating status information or the power limit.

[0104] In one embodiment, instead of selecting a main charging pile and determining a charging strategy for the main charging pile, the internal management module of the charging piles that are currently charging, or a preset number of, or all of the charging piles can be used to perform the determination of the charging strategy, wherein the charging strategy management determines the charging piles for that charging strategy.

[0105] In one embodiment, the management module 300 can perform the task of determining the charging strategy, and the charging strategy can be executed on the charging piles that are currently charging, or on a preset number of charging piles, or on all charging piles.

[0106] The charging strategy of this application embodiment can be obtained by selecting or combining different charging strategies of the present invention embodiment.

[0107] The charging strategy in this invention includes, but is not limited to, controlling the charging piles to perform charging operations according to the order in which charging requests are received. In one embodiment, charging operations are performed first on one or more charging piles that have submitted charging requests, and then other charging operations are performed after the charging requests are completed.

[0108] The charging strategy of this invention includes, but is not limited to, controlling corresponding charging piles to perform charging operations during preset charging time periods. In one embodiment, multiple charging piles performing charging operations are carried out in turn during different charging time periods. For example, this can meet the needs of users with urgent short-distance travel, allowing them to pick up the vehicle immediately after it has been fully charged.

[0109] The charging strategy in this embodiment of the invention includes, but is not limited to, controlling each charging pile to charge based on its priority. In this embodiment, the management module 300 is also used to receive signal data from the terminal device. The signal data from the terminal device includes user-set priorities. Charging is first performed on one or more charging piles with higher priorities.

[0110] The charging strategy of this invention includes, but is not limited to, controlling each charging pile to perform charging operations in turn based on the preset power level of each charging pile. In one embodiment, the preset power level is used to charge multiple charging piles in turn. For example, this can meet the needs of users with urgent short-distance travel, allowing them to pick up the vehicle immediately after it has reached a sufficient preset power level.

[0111] The charging strategies of this invention include, but are not limited to, simultaneously charging multiple charging piles at a preset charging power. In one embodiment, the preset charging power is lower than the demand management of the charging piles, ensuring that the total power demand of the charging piles is lower than or equal to the power limit. For example, during nighttime vehicle charging, one or more charging piles are simultaneously charged at a low power. After charging is complete, all charging piles are turned off or put into hibernation to save power.

[0112] The charging strategy in this invention includes, but is not limited to, taking turns charging multiple charging piles based on their charging pile numbers. In one embodiment, the charging pile with the highest number is charged first. For example, in a public parking lot, charging the charging pile with the highest number is charged first to facilitate charging pile management. This could be because the charging pile with the highest number is a first-in, first-out location, or because customer levels are set.

[0113] In one embodiment, the charging strategy described above in this invention can be pre-stored in a management module inside the charging pile. The method by which the management module inside the charging pile determines the charging strategy includes selecting or combining preset charging strategies. For example, when the total power demand of a high-priority charging pile is lower than a power limit, a priority-based charging strategy can be combined with a charging strategy based on a preset charging time period to obtain the final required charging strategy. The priority-based charging strategy is used to perform charging operations on the high-priority charging pile. The charging strategy based on a preset time period, within the remaining power limit after the priority-based charging strategy is executed (i.e., the difference between the power limit and the total power demand of the high-priority charging pile), is used for the low-priority charging pile to execute the charging strategy.

[0114] In one embodiment, the communication module of the charging pile of this invention can also receive signal data from the terminal device, as well as charging pile-related information sent to the terminal device. The signal data from the terminal device includes processing operation information for the corresponding charging pile, such as fault handling, charging time adjustment, and charging pile priority adjustment. The charging pile-related information sent to the terminal device includes the charging pile's operating status, such as the time required to complete charging, the charging power of the charging pile, and the charging pile's priority. In one embodiment, when the internal management module of the main charging pile determines the charging strategy, it also needs to meet the content requirements of the signal data from the terminal device.

[0115] In step S405, multiple charging stations execute the charging strategy.

[0116] In one embodiment, multiple charging piles that are currently charging may receive and execute the charging strategy, or all charging piles may receive and execute the charging strategy.

[0117] In one embodiment, multiple charging piles other than the main charging pile that are currently charging can be referred to as slave charging piles. Slave charging piles need to receive and execute charging strategies. When the main charging pile is currently charging, it needs to determine and send the charging strategy, as well as receive and execute it. When the main charging pile is not currently charging, it needs to determine and send the charging strategy. The communication modules of all the multiple charging piles currently charging receive the charging strategy, and their internal management modules execute it.

[0118] In one embodiment, the management module inside the charging pile may not receive and execute the charging strategy; instead, the management module inside the main charging pile controls the charging operation of the charging pile through the charging strategy.

[0119] In one embodiment, the present invention may also omit the inter-pile self-organizing network and execute the relevant contents of steps S403, S404 and S405 based on the communication connection. This application embodiment is not limited here.

[0120] In the above embodiments, the charging piles involved include, but are not limited to: AC charging pile networks for electric vehicles and low-power DC charging pile networks. The internal management module of a charging pile generally refers to a module with processing functions, which can be a microprocessor (MCU), an embedded ARM processor, or even a cloud server; this application embodiment does not limit this. The communication module of a charging pile generally refers to a module with communication functions, which can be a wired communication component or a wireless communication component. For example, to simplify the wiring layout, the communication module of the charging pile can be specifically set as a wireless communication component, such as a chip component for Wireless Fidelity (Wi-Fi), a chip component for Bluetooth technology, a chip component for Zigbee technology, or a chip component for Long Range (LoRa) data transmission technology, etc., so that the self-organizing network between charging piles can transmit signals wirelessly. To improve charging safety and reduce the probability of charging hazards in practical applications, the communication module of the charging pile can be specifically selected as a wired communication component, such as an RS-232 standard interface component (recommended standard, RS), so that the charging piles in the self-organizing network can transmit signals through wired communication. In one embodiment, the charging pile can also be equipped with both wired and wireless communication components to meet different needs in practical applications. This application does not limit the scope of the embodiments described herein.

[0121] The following describes the implementation process of the technical solution of the embodiments of this application from the software perspective.

[0122] In this embodiment, for charging pile manufacturers, in order to realize the functions of inter-pile self-organizing network and adaptive power limiting, it is necessary to develop control software for managing the charging piles and install it in the charging piles. In one embodiment, it is installed in the internal management module of the charging pile. When preset usage conditions are met, the control software is activated to control the charging pile to perform charging operations, including detecting the charging pile's working status information, determining, sending, receiving, and executing charging strategies, etc. Figure 5 This is a flowchart illustrating the process of establishing a charging management method as provided in the embodiments of this application, such as... Figure 5 As shown, the specific implementation process is as follows:

[0123] Step S501: Determine the power limit.

[0124] In one embodiment, the charging pile's control software controls the charging pile's internal management module to acquire data signals from other devices, including whether a power meter is installed, the power meter's power information, the available power of the power system's remaining capacity, and information about other devices connected to the power system. Based on the data signals acquired from other devices, the internal management module determines power limits to restrict the charging operation of the charging pile. The methods for determining power limits include: pre-setting power limits based on the rated power of the power meter; pre-setting power limits based on the available power of the power system's remaining capacity; and dynamically determining power limits based on a pre-set strategy. Further details are omitted here.

[0125] Step S502: Send charging pile working status information.

[0126] In one embodiment, the control software of the charging pile controls the internal management module of the charging pile to obtain the charging pile's operating status information, including the charging pile's power consumption and whether the charging pile is in charging operation. Through a communication connection, the communication module can send the charging pile's operating status information to the communication modules of other charging piles. Simultaneously, the charging pile's communication module also receives charging pile operating status information from other charging piles.

[0127] Step S503: Select the main charging pile.

[0128] In one embodiment, a self-organizing network between charging piles can be established, or a main charging pile can be selected from multiple charging piles operating at the charging level, or from all charging piles, based on the charging pile's operational status information via communication connection. The main charging pile can be selected based on charging pile number, the order of access to charging, or random selection. Multiple backup main charging piles can also be selected. This is used when the management module inside the main charging pile malfunctions and cannot determine and send the charging strategy; in this case, a backup main charging pile can be selected as the main charging pile to complete the determination and transmission of the charging strategy, thus ensuring the charging operation continues.

[0129] Step S504: Determine whether the charging pile belongs to the main charging pile.

[0130] In one embodiment, for example, after identifying the main charging pile, a signal is sent to the main charging pile, enabling its internal management module to receive the signal and determine the charging strategy. If the charging pile receives the signal, the result of determining whether it is the main charging pile is "yes"; otherwise, the result is "no". Alternatively, an enable signal can be used to enable the main charging pile's internal management module to perform the work of determining the charging strategy and determining whether it is the main charging pile.

[0131] Step S505: Determine and send the charging strategy.

[0132] In one embodiment, this step is performed if the charging pile belongs to a main charging pile. Based on the charging pile's operating status information or power limit, the main charging pile determines a charging strategy to perform the charging operation. While meeting the power limit requirements, the charging pile's internal management module determines the charging strategy to achieve optimal charging efficiency.

[0133] In one embodiment, the charging strategy of this invention includes, but is not limited to: controlling the charging piles to perform charging operations according to the order in which charging requests are received; controlling the corresponding charging piles to perform charging operations within a preset time period; controlling each charging pile to perform charging operations based on its priority; controlling each charging pile to perform charging operations in turn based on its preset power capacity; controlling multiple charging piles to perform charging operations simultaneously; and controlling multiple charging piles to perform charging operations in turn based on their charging pile numbers. The above-mentioned charging strategy of this invention can be pre-stored in the management module inside the charging pile. The method by which the management module inside the charging pile determines the charging strategy includes: selecting or combining preset charging strategies.

[0134] Step S506: Receive and execute the charging strategy.

[0135] In one embodiment, the main charging pile, or a slave charging pile when the result of determining whether it is a main charging pile is "no" (where slave charging piles refer to multiple charging piles other than the main charging pile that are currently charging), receives the charging strategy through a communication module and then executes the charging strategy through its internal management module, or directly receives and executes the charging strategy through the communication module. The execution actions of the charging strategy include starting charging, pausing charging, and ending charging.

[0136] Figure 6 This is a flowchart illustrating the usage process of a charging management method provided in an embodiment of this application. Figure 6 As shown, this method is executed when a device to be charged is connected to a charging station, or when a charging station has completed its charging operation. The specific steps are as follows:

[0137] Step S601: Send the charging pile working status information.

[0138] In one embodiment, when a device with charging needs connects to a charging pile, or when a charging pile completes its charging operation, the internal management module of that charging pile sends its charging pile operating status information. Upon receiving this information, the internal management module of the main charging pile updates the previous charging pile operating status information. Based on the power limit and the updated operating status information of multiple charging piles, the charging strategy is determined. For example, when a device connects to a charging pile, the number of charging piles currently charging increases, and the total power demand of the charging piles increases. Due to the power limit, the charging strategy needs to be redefined and resent. Conversely, when a charging pile completes its charging operation, the number of charging piles currently charging decreases. Due to the power limit, there is surplus power, requiring a re-determination and execution of the charging strategy to improve the utilization rate of the remaining power capacity of the power system and increase the efficiency of the charging operation.

[0139] In one embodiment, when a device to be charged connects to a charging pile, or when a charging pile completes its charging operation, it can be determined whether a new primary charging pile needs to be selected to improve charging efficiency. For example, when implementing a charging strategy where multiple charging piles take turns charging, the charging pile with the later priority can be changed to the primary charging pile. This avoids the charging pile having to perform two tasks: determining and executing the charging strategy, which reduces work efficiency. When implementing a charging strategy that charges according to priority, the charging pile with the lower priority can be changed to the primary charging pile, thus improving charging efficiency.

[0140] In one embodiment, the charging pile's operational status information can be transmitted via an inter-pile ad-hoc network or communication connection. For example, the ad-hoc network component of the communication module of the charging pile currently charging, or all charging piles, is always enabled (e.g., Bluetooth or wireless network components). When a device to be charged connects to the charging pile, the ad-hoc network component of the communication module receives the charging pile's operational status information from the newly connected charging pile and updates this information to the operational status information of the multiple charging piles currently charging, thereby re-determining the charging strategy. To conserve power, the ad-hoc network component of the main charging pile's communication module can also be kept always enabled, with the internal management modules of the other charging piles only activating when the main charging pile's ad-hoc network component sends a data signal. Alternatively, the self-organizing network components of the communication modules of all charging piles can remain in a closed state. When data needs to be sent or received, or when the communication module of the main charging pile receives the charging pile working status information of a newly connected charging pile, a start signal is sent to the communication modules of the other charging piles through the internal management module of the main charging pile to enable the self-organizing network components of the communication modules of the other charging piles.

[0141] Step S602: Redetermine and send the charging strategy.

[0142] In one embodiment, the management module inside the main charging pile re-determines the charging strategy and controls the communication module of the main charging pile to resend the charging strategy.

[0143] In one embodiment, in order to improve charging efficiency, increase the utilization rate of the available power of the power system's remaining power, and improve the user experience, it is necessary to redetermine the charging strategy.

[0144] In one embodiment, when a device to be charged connects to a charging pile, the total power of the charging piles already charging may increase further, potentially exceeding the power limit. First, the operating status information of the newly connected charging pile, such as its priority, is determined. Second, based on the determination result, the operating status information of the charging piles already charging is updated. Finally, based on the updated operating status information of the charging piles already charging, the charging strategy is redefined and adjusted. For example, if the newly connected charging pile has a high priority, a priority-based charging strategy and a pre-set time-based charging strategy can be combined to obtain the final charging strategy. For example, the priority-based charging strategy is used to perform charging operations on high-priority charging piles; the pre-set time-based charging strategy is used for lower-priority charging piles within the remaining power limit after the priority-based charging strategy is executed.

[0145] In one embodiment, when a charging pile completes its charging operation, residual power is generated, necessitating timely updates to the charging pile's operational status information to improve charging efficiency. For example, when a charging pile completes its charging operation, analysis reveals that the total power of the charging piles currently charging is below a power limit. The operational status information of these charging piles is then updated, and the charging strategy of charging according to a preset power level is changed to a strategy of simultaneously charging multiple charging piles.

[0146] In one embodiment, the charging piles currently charging can be re-established through an inter-pile ad-hoc network to send charging strategies. When a device waiting to be charged connects to a charging pile, or when a charging pile completes its charging operation, changes in the working status information of the charging piles currently charging, including changes in the number of charging piles currently charging and the power consumption of the charging piles, necessitate re-establishing the inter-pile ad-hoc network to send new charging strategies.

[0147] Step S603: Re-receive and execute the charging strategy.

[0148] In one embodiment, when a device to be charged is connected to a charging pile, or when a charging pile completes a charging operation, the charging pile that is currently charging receives and executes the charging strategy again based on the updated charging strategy.

[0149] In one embodiment, after receiving a new charging strategy, the charging station executing the new strategy can perform the following actions: first, follow the original charging strategy for a preset time; second, charge for a predetermined amount of electricity; or third, charge until the preset charging station has completed its charging operation, and then execute the newly received charging strategy. A charging station already charging can directly execute the newly received charging strategy after receiving a new one.

[0150] In this embodiment of the invention, when a charging pile that is currently charging executes a re-receiving charging strategy, if a device to be charged is connected to the charging pile, or if a charging pile has completed its charging operation, the method is executed again.

[0156] In one embodiment, the processing unit 702 is specifically used to select a main charging pile from the plurality of charging piles, the main charging pile being used to determine a charging strategy.

[0157] In one embodiment, the processing unit 702 is specifically used to acquire the charging pile operating status information of the plurality of charging piles, the charging pile operating status information including the power consumption of the charging pile and whether the charging pile is in charging operation state; and to determine the charging strategy based on the power limit and the charging pile operating status information of the plurality of charging piles.

[0158] In one embodiment, the processing unit 702 is specifically used to receive signal data from the terminal device; and the determination of the charging strategy is also related to the signal data from the terminal device.

[0159] In one embodiment, the charging strategy includes: controlling the charging piles to perform charging operations according to the order in which charging requests are received; controlling the corresponding charging piles to perform charging operations within a preset time period; controlling each charging pile to perform charging operations based on the priority of each charging pile; controlling each charging pile to perform charging operations in turn based on the preset power capacity of each charging pile; controlling multiple charging piles to perform charging operations simultaneously; and controlling multiple charging piles to perform charging operations in turn based on the charging pile numbers of the multiple charging piles that are currently performing charging operations, one or more of the following.
