Description

Technical Field

[0001] The present invention relates to the technical field of Internet of Things, and in particular to an IPv6-based intelligent networked charging pile system. Background Art

[0002] At present, with the rapid development of new energy vehicles in recent years, charging piles have also been rapidly popularized. Especially with the deep integration of new technologies such as cloud computing, big data, the Internet of Things, and artificial intelligence with electric vehicle charging, energy trading and balance, the electric vehicle charging infrastructure has gradually evolved towards green, wireless, intelligent, and autonomous driving. However, the existing charging pile operator's independent networking and operation model seriously restricts the further development of the charging pile industry. The current intelligent charging pile system is mainly composed of three parts: charging pile hardware equipment, operator business management platform, and mobile terminal application. It mostly adopts a distributed architecture based on IPv4 (Internet Protocol Version 4) Ethernet. The communication between the charging pile and the business management platform is mainly realized by TCP / IP (Transmission Control Protocol / Internet Protocol). The platform and the pile body are deployed in the same enterprise's proprietary network environment, and are interconnected and communicated through a local area network or the Internet. With the help of 4G / 5G, cloud computing and other technologies, the sharing and payment of charging piles are realized. There are currently many common charging pile communication protocols, such as OCPP (Open Charge Point Protocol), CAN (Controller Area Network), Modbus (Modbus Protocol) and MQTT (Message Queuing Telemetry Transport). These protocols have their own characteristics and are suitable for different application scenarios. The OCPP protocol is often used as a charging station communication protocol, the CAN protocol is mainly used for internal vehicle communication, the Modbus protocol is often used in the field of industrial automation, and the MQTT protocol is suitable for low-bandwidth, high-latency IoT scenarios. However, these protocols have certain limitations in the application of electric vehicle charging, such as lack of standardization, poor interoperability, and the inability to form unified management.

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] First, the existing charging piles use the distributed architecture of IPv4 Ethernet. Affected by the shortage of IPv4 addresses, each operator uses a proprietary network to realize charging pile billing management. Different private networks cannot be interconnected, and there are a large number of overlapping IPv4 private addresses, which makes it impossible to form a global management mode. The charging pile must be connected to a private network and communicate with the outside world through a designated business platform. Users need to install APPs (Applications) developed by different charging pile operators to search for piles, make reservations, pay, and other services. It is not convenient and fast to use, and the user experience is not good. Because there are a lot of overlaps in private IP (Internet Protocol) addresses, they cannot be directly recognized by the Internet. NAT (Network Address Translation) must be used to convert internal IP addresses into available IP addresses on the Internet, so as to realize the communication between the internal IP addresses of the private network and the external Internet, which will reduce the transmission efficiency of the system network. At the same time, since common charging pile communication protocols such as OCPP, CAN, Modbus, and MQTT have not formed a unified access standard that supports IPv6 (Internet Protocol Version 6), it is impossible to form a global management model, and it is impossible to achieve functions such as full network interaction, intelligent early warning, and vehicle-pile transactions, which restricts the development of electric vehicle charging infrastructure.

[0028] Secondly, most of the current personal charging piles do not have the ability to connect to the Internet and operate independently, and most of the time they are idle, resulting in a waste of resources. Sharing private charging piles can activate idle resources, but safety, compatibility and cost issues have become the main problems that plague shared private charging piles.

[0029] Finally, there is currently no universal charging pile identification and coding specification, the charging facility data is scattered and the standards are inconsistent. Although some regions have issued relevant local standards, there is no correlation and universality between the local standards, and it is impossible to form a universal charging pile unified coding rules and standards. Moreover, all current charging pile identification codes only have the function of carrying information and do not have communication capabilities.

[0030] Based on this, an embodiment of the present invention provides an IPv6-based smart networked charging pile system, which adopts a layered system architecture. By inventing a city-level IPv6 smart charging pile public, open access cloud platform and a universal IPv6 smart charging pile network access chip / module, smart charging piles with independent networking and operation capabilities are produced. By utilizing the pure IPv6 end-to-end characteristics, individuals and piles of various operators can smoothly access the IPv6-based smart networked charging pile system, realizing the "decentralization and de-platforming" of the smart charging pile system, and creating an interconnection mode between the platform and the pile body MN.

[0031] To facilitate understanding of this embodiment, an IPv6-based intelligent networked charging pile system disclosed in an embodiment of the present invention is first introduced in detail.

[0032] Embodiment 1:

[0033] The embodiment of the present invention provides an IPv6-based intelligent network charging pile system, see Figure 1 The structure diagram of an IPv6-based intelligent networked charging pile system shown in the figure includes: an intelligent charging pile access platform, multiple operators or individuals' IPv6-based charging piles, multiple operators' charging pile platforms, a third-party new energy vehicle application system, an electric vehicle with vehicle-mounted communication, and a supervision system;

[0034] Each client, platform and charging pile in the IPv6-based intelligent network charging pile system are connected to the IPv6 Internet through a unified IPv6 charging pile communication access standard;

[0035] The smart charging pile access platform is used for the registration, access authentication and authorization of charging piles; interconnection with the supervision system and charging pile platform; and providing an open standard interface to third-party new energy vehicle application systems;

[0036] Multiple IPv6-based charging piles are all provided with an IPv6 communication module for accessing the intelligent networked charging pile system through a unified IPv6 intelligent charging pile network access standard;

[0037] The charging pile platforms of multiple operators are used to access the intelligent networked charging pile system through the unified IPv6 intelligent charging pile network access standard;

[0038] The third-party new energy vehicle application system is used to connect to the smart charging pile access platform through an open standard interface;

[0039] Electric vehicles with on-board communications are provided with an IPv6 communication module for accessing the intelligent networked charging pile system through a unified IPv6 intelligent charging pile network access standard;

[0040] The supervision system is used to implement centralized supervision of charging piles within a city on a city basis.

[0041] This embodiment discloses a charging pile intelligent networking method based on IPv6, which can be found in Figure 2 The diagram shows the structure of an intelligent networked charging pile system based on IPv6. The system includes an intelligent charging pile access platform 1, an IPv6-based charging pile 2 of operator #1, an IPv6-based charging pile 3 of operator #2, a personal IPv6-based charging pile 4, an operator #1 charging pile platform / APP 5, an operator #2 charging pile platform / APP 6, a third-party new energy vehicle application system / APP 7, an electric vehicle (including vehicle-mounted communication) 8, and a supervision system 9. All clients, platforms, and charging piles are connected to the IPv6 Internet through a unified IPv6 charging pile communication access standard. There can be multiple third-party new energy vehicle application systems / APPs, charging piles, and electric vehicles (including vehicle-mounted communication) in the system. Figure 2 Only one case when two operators are connected is shown. Theoretically, the number of operators can be increased infinitely. When one or more operators are connected, the present invention is applicable.

[0042] The system adopts IPv6 single-stack networking, breaking through the limitations of existing private IPv4 networks. All clients, platforms and charging piles in the system are connected to the IPv6 Internet through a unified IPv6 charging pile communication access standard, achieving end-to-end information exchange and communication.

[0043] In some embodiments, the above-mentioned IPv6 network provides encryption and authentication mechanisms through the IPsec protocol.

[0044] Compared with IPv4 networks, IPv6 provides a faster end-to-end communication method, greatly improving network efficiency. At the same time, IPv6 provides more security mechanisms, such as built-in support for the IPsec (Internet Protocol Security) protocol, which provides encryption and authentication mechanisms for IPv6 network connections, making the IPv6-based charging pile intelligent network system more secure and ensuring the integrity and confidentiality of end-to-end communications at the network layer.

[0045] The smart charging pile access platform 1 is the "brain" of the smart networked charging pile system based on IPv6, and its functions include at least: charging pile registration and access authentication and authorization; interconnection with the supervision system 9 and the operator charging pile platform / APP 5 / 6; and providing an open standard interface to the third-party new energy vehicle application system / APP 7, so that third-party developers can develop special new energy vehicle applications / APPs based on the standard interface. By introducing the smart charging pile access platform 1, loose coupling between charging piles and new energy vehicle applications can be achieved, allowing new energy vehicle applications to connect with multiple operator charging piles at the same time.

[0046] The IPv6-based charging pile 2 of operator #1, the IPv6-based charging pile 3 of operator #2 and the personal IPv6-based charging pile 4 are the "foundation" of the IPv6-based intelligent networked charging pile system. They are all equipped with IPv6 communication modules and connected to the intelligent networked charging pile system through the unified IPv6 intelligent charging pile network access standard. Because they have a globally unique IPv6 address, they can directly communicate with the intelligent charging pile access platform 1, the operator's charging pile platform / APP 5 / 6, the third-party new energy vehicle application system / APP 7 and the electric vehicle (including vehicle communication) 8 end-to-end, realize cross-platform linkage, obtain the current battery status and charging requirements of the electric vehicle, and allow users to view the charging progress and status in real time while waiting for charging. At the same time, since the IPv6 network connection provides IPsec encryption and authentication mechanisms, it avoids the leakage of user personal information in the process of obtaining battery charging data, and strengthens user privacy protection.

[0047] Operator #1 charging pile platform / APP 5 and operator # do not change the operator's own business structure.

[0048] The third-party new energy vehicle application system / APP 7 is connected to the smart charging pile access platform 1 through an open standard interface (such as API, etc.). The third party can develop a special new energy vehicle application / APP based on the standard interface, thereby realizing the loose coupling between the charging pile and the new energy vehicle application, and allowing the new energy vehicle application to be connected with the charging piles of multiple operators at the same time. Users can use any third-party new energy vehicle application system / APP in the system to search for the charging piles of multiple operators or personal charging piles in the system, and even realize the location query, idle status display, optimal route planning, online reservation, touchless payment and other services of the charging piles in the whole network according to the special business of the third-party developer.

[0049] In some embodiments, the electric vehicle with on-board communication is also used to feed back the current battery status and charging requirements of the electric vehicle to the charging pile, and synchronously display the charging time and battery charging status.

[0050] The electric vehicle (including on-board communication) 8 is equipped with an IPv6 communication module, which accesses the intelligent networked charging pile system through the unified IPv6 intelligent charging pile network access standard. It can directly communicate with the charging pile, and safely feed back the current battery status and charging requirements of the electric vehicle to the charging pile, and simultaneously display the charging time and battery charging status, so that users can understand the charging process more intuitively.

[0051] The supervision system 9 follows the unified access standard, allowing centralized supervision of all charging piles in the city on a city-by-city basis. By introducing IPv6 technology, the IPv6-based charging pile 2 of operator #1, the IPv6-based charging pile 3 of operator #2, and the IPv6-based charging pile 4 of individuals can all obtain globally unique IPv6 addresses. The supervision system 9 connects to the smart charging pile access platform 1 through an open standard interface (such as API, etc.), thereby obtaining the geographic location, working status, charging power, battery status, temperature and other information of all charging piles in the system in real time, and realizing remote monitoring and unified intelligent management of all smart charging piles in the system.

[0052] An IPv6-based smart networked charging pile system provided in an embodiment of the present invention adopts a layered system architecture, and produces smart charging piles with independent networking and operation capabilities by inventing a city-level IPv6 smart charging pile public, open access cloud platform and a universal IPv6 smart charging pile network access chip / module. By utilizing the pure IPv6 end-to-end characteristics, individuals and piles of various operators can smoothly access the IPv6-based smart networked charging pile system, thereby realizing the "decentralization and de-platforming" of the smart charging pile system and creating an interconnection mode between the platform and the pile MN.

In some embodiments, the above-mentioned charging pile based on IPv6 is provided with: an operation screen module, a central processing unit, a data storage module, a control module, a charging module and an IPv6 communication module.

[0055] In some embodiments, the IPv6 communication module set in the above-mentioned charging pile is used to be equipped with corresponding peripheral circuits according to the type of charging pile, to form a standard communication and control interface of the charging pile main control unit, and to form a standard physical size; the IPv6 communication module set in the charging pile is connected to the central processing unit, and is used to connect the charging pile to the intelligent networked charging pile system.

[0056] See also Figure 3The figure shows a schematic diagram of the internal modules and external connections of an IPv6-based smart networked charging pile device. The appearance of the IPv6-based smart networked charging pile device provided in this embodiment is similar to that of an existing charging pile. The smart networked charging pile device is internally provided with an operation screen module (preferably a liquid crystal touch screen), a central processing unit, a data storage module, a control module, a charging module and an IPv6 communication module.

[0057] Unlike existing charging piles, an IPv6 communication module 100 is added inside the charging pile provided by the present invention, so that the charging pile has independent networking and operation capabilities. The IPv6 communication module 100 needs to be equipped with corresponding peripheral circuits according to different charging pile types to form a standard communication and control interface with the charging pile main control unit, and form a standard physical size to reduce the manufacturer's R&D and production investment. The IPv6 communication module 100 is connected to the central processor to enable the charging pile to be connected to the IPv6-based intelligent networked charging pile system, so that the charging pile can obtain a globally unique IPv6 address, thereby communicating end-to-end with the platform and charging pile application system in the system, and realizing functions such as pile body query, charging appointment, and contactless payment.

[0058] Embodiment three:

[0059] The embodiment of the present invention provides another intelligent networked charging pile system based on IPv6. This embodiment is implemented on the basis of the above embodiment, and focuses on describing the IPv6 communication chip. In some embodiments, the core of the IPv6 communication module set in the above charging pile is the IPv6 communication chip; the IPv6 communication chip is integrated and encapsulated with the IPv6 digital space identity.

[0060] See also Figure 4 A schematic diagram of the structure of an IPv6 communication module is shown. The core of the IPv6 communication module 100 is a universal IPv6 communication chip 101. The IPv6 communication chip 101 should integrate and encapsulate an independent and legal IPv6 digital space identity, as well as IPv6 unified access, blockchain anti-tampering, digital RMB transaction and other capabilities, so that the charging piles have an independent and legal communication identity on the Internet, allowing all new smart charging piles including personal charging piles to connect to multiple operator platforms at the same time, truly realizing the sharing economy.

[0061] In some embodiments, the above-mentioned IPv6 digital space identity is an IPv6 address; the IPv6 address includes: prefix, location information, production information, reserved subnet, charging pile body information and interface ID.

[0063] See also Figure 5 The present invention discloses a method of using IPv6 address as charging pile digital identity identification, which aims to ensure the unified coding of electric vehicle charging facilities. The IPv6 address space is 10 38 The massive address space is sufficient to support the digital identity system. Using IPv6 addresses as digital identity identifiers for charging piles makes the identification code of charging piles unique, universal, and convenient. It not only has the function of information bearing, but also has direct communication capabilities. Figure 5 Introducing a charging pile identification coding structure based on IPv6 address:

[0064] An IPv6 address consists of 128 bits, which are divided into 8 groups in hexadecimal, with each group separated by a ":".

[0108] Embodiment seven:

[0109] The embodiment of the present invention provides another IPv6-based intelligent networked charging pile system. This embodiment is implemented on the basis of the above embodiment, and focuses on describing the communication process based on IPv6 between the supervision system and the intelligent charging pile access platform using the above IPv6 intelligent networked charging pile system. Fig. 9 A schematic diagram of the communication process between a supervision system and an access platform based on IPv6 includes the following steps:

[0110] Step 601, the supervision system is initialized and registration / login is performed.

[0111] Step 602: The smart charging pile access platform server performs identity authentication. If the identity authentication is successful, execute step 603; if the identity authentication is unsuccessful, execute step 604.

[0112] Step 603: After the identity verification is successful, the supervision system and the access platform server are successfully connected. If a link is broken after the supervision system and the access platform server are successfully connected, step 604 is executed; if the communication is normal, step 605 is executed.

[0113] Step 604: After identity verification fails or the link is disconnected, the system automatically attempts to connect. If the connection is successful, step 603 is executed; if the connection is unsuccessful, step 610 is executed.

[0114] Step 605, the access platform server issues corresponding permissions according to the registration information. The present invention adopts hierarchical permission setting: the first-level super administrator has the highest level of system management authority and can manage and configure all resources of the system, including security settings, user authority allocation, charging pile grouping, etc.; the second-level system operation and maintenance administrator is responsible for the daily operation and maintenance of the system, and can perform system configuration, user management and other operations; the third-level system inspector is responsible for monitoring the charging pile data and tracking the alarm accidents, has the management authority of specific applications, and can perform basic application operations and program upgrades, etc.

[0115] Step 606: Log in to the supervision system account and initiate a request for charging pile information.

[0116] Step 607, the smart charging pile access platform server agrees to supervise the charging pile sensor and communication module data within the system call authority based on the account authorization, including at least the total number of charging guns, the number of idle charging guns, the maximum charging current, the maximum charging voltage, the charging reservation time, the charging process, the temperature, and the system status.

[0117] Step 608: The supervision system monitors the basic parameters, working status and other data of the charging pile in real time and performs analysis and processing.

[0118] In step 609, the monitoring system compares the real-time data of the charging pile with the fault warning threshold set in advance. Once the data exceeds the threshold, step 611 is executed. If the data is normal, this step is always executed.

[0119] In step 610, the system performs error reporting and pushes corresponding error and warning information to personnel at all levels of the supervision system.

[0120] Step 611, the system alarm is triggered and the faulty charging pile is stopped urgently. At the same time, the location of the charging pile is informed to the rescue personnel to facilitate the first-time rescue.

[0121] Step 612, end.

[0122] In summary, the embodiments of the present invention mainly provide the following contents:

[0123] 1. Use IPv6 digital space identity so that each charging pile has an IPv6 identity independent of the network location, which is convenient for lifelong tracking and maintenance of charging piles, and also convenient for automatic networking of charging piles, reducing the difficulty of network distribution. Common charging pile identification does not have communication capabilities, but through the resolution system with IPv6 address as digital identity, it can not only realize identification allocation, registration and resolution services within the enterprise charging pile, but also realize external communication. The external communication address is the IPv6 address prefix of the internal identification.

[0124] 2. A hierarchical structure is adopted, and a public access platform is introduced to separate the construction and maintenance of charging piles from business operations. Third-party developers are allowed to develop special businesses based on charging piles of different operators. Each charging pile APP can connect to multiple operators' charging piles at the same time, which is convenient for users. It also allows centralized supervision of all charging piles in the city on a city basis to eliminate safety hazards.

[0125] 3. Using IPv6 single-stack networking, each charging pile has an independent and legal communication address on the Internet, breaking through the limitations of existing private IPv4 networks. It can be directly connected to multiple operator platforms and even independently operated by connecting to maps such as Gaode and Baidu.

[0126] In summary, the above contents provided by the embodiments of the present invention mainly have the following advantages:

[0127] The present invention realizes the hierarchical structure of charging piles, access platforms, and application systems by stipulating the interface standards between charging piles and access platforms, charging piles and mobile phone terminals, access platforms and application systems, access platforms and supervision systems, and access platforms and operator cloud platforms, allowing independent investment, construction, and operation and maintenance of charging piles, and developing and deploying access platforms and system applications separately, forming a loosely coupled architecture between operators and pile bodies, and creating an interconnection mode between the platform and pile body MN. First of all, through the present invention, users only need to install any third-party new energy vehicle application system / APP in the system to search, make reservations, pay, and other operations for IPv6-based intelligent networked charging piles of different operators or individuals in the system, greatly improving the user experience. In addition, the supervision system can unify the basic information and operation status of all intelligent networked charging pile devices in the system in real time, realizing intelligent management while also greatly ensuring the security and privacy of charging pile site information and user data.

[0128] Secondly, the present invention configures an IPv6 communication chip for the smart charging pile. The chip integrates and encapsulates an independent and legal IPv6 digital space identity, as well as IPv6 unified access, blockchain anti-tampering, digital RMB transactions and other capabilities, so that the charging pile has a legal communication identity on the Internet, enabling it to have independent operation and settlement capabilities, allowing all new smart charging piles including personal charging piles to connect to multiple operator platforms at the same time, truly realizing the sharing economy. Through the present invention, personal charging piles are also included in the supervision system, greatly reducing the safety risks of electrical failures and random charges during the use of personal charging piles. The basic information of the charging pile, such as model, interface, and electrical, can be viewed through a third-party APP, which is convenient for users to identify and solve the problem of compatibility of shared private charging piles.

[0129] Finally, the present invention integrates and encapsulates an independent and legal IPv6 digital space identity for the charging pile communication chip, and discloses a coding method using the IPv6 address as the charging pile identity, which ensures the consistency and uniqueness of the charging pile coding, and can completely solve the problem of scattered charging facility data and different standards. In addition, the IPv6 address is internationally recognized, has universality and applicability, and has communication capabilities, which helps to effectively manage charging facilities, promote the interconnection of information between various manufacturers and operators, improve the quality of charging facility data, and promote the charging pile industry to better provide services to the society.
