Description

Technical Field

[0001] The present invention relates to the technical field of blockchain connection, and in particular to a smart charging device, system and charging method based on blockchain connection. Background Art

[0002] With the widespread popularity of electric vehicles, the convenience and efficiency of charging facilities have become increasingly key concerns for the development of the industry. In existing charging scenarios, when users drive electric vehicles to charging stations for charging, there are generally many inconveniences and inefficiencies.

[0003] The traditional charging process requires users to manually scan the QR code on the charging pile to start the charging process after parking. This process is not only cumbersome, but also requires users to operate accurately. In the case of poor network signal or damaged or blurred QR code, it is very easy to cause charging startup failure, which consumes a lot of users' time and energy.

[0004] A more prominent problem is the poor maintenance of charging piles. Due to the lack of effective real-time monitoring and early warning mechanisms, users often encounter multiple damaged charging piles in succession. These damaged charging piles may have problems such as charging interface failure, abnormal power transmission, or internal circuit short circuit, resulting in the inability to charge the electric vehicle normally. Users have to try to find available charging piles one by one. This process greatly affects the charging efficiency, greatly prolongs the user's originally short charging waiting time, and seriously reduces the user experience.

[0005] Moreover, the existing charging system has obvious lag and opacity in the information exchange between users and charging piles and charging station operators. It is difficult for users to know the real-time working status of each charging pile in advance, and the operator cannot obtain the fault information of the charging pile in time for rapid maintenance, which further aggravates the waste of charging resources and inconvenience in use.

[0006] To sum up, the existing electric vehicle charging mode urgently needs an innovative solution that can simplify the charging operation process, monitor the status of charging piles in real time and realize efficient information interaction to improve charging efficiency and user satisfaction. The emergence of smart charging devices, systems and charging methods based on blockchain connection is particularly urgent and necessary, and is expected to bring new changes and breakthroughs to the field of electric vehicle charging.

[0007] In response to the above technical problems, the present invention proposes an intelligent charging device, system and charging method based on blockchain connection, which can effectively improve the efficiency of users using charging piles, avoid long waiting time for vehicles and excessive energy loss, and ultimately improve the user experience of using charging piles.

[0009] Furthermore, the entry information includes a vehicle identification code, an entry time and a current location.

[0010] Furthermore, the measurement method includes any one of RSSI ranging, Bluetooth 6.0 channel ranging, AOA ranging and AOD ranging.

[0011] Furthermore, if all the charging piles in the charging station detect that the vehicle to be charged is not within the preset range, all the charging piles in the charging station stop measuring the distance of the vehicle to be charged.

[0012] Furthermore, the intercommunication information includes vehicle battery information, commonly used charging pile status information and other charging pile status information.

[0025] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0026] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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. The present invention will be specifically described below in conjunction with the accompanying drawings: A smart charging system based on blockchain connection, such as Figure 1 As shown, it includes several charging piles and vehicles to be charged.

[0028] Any one of the plurality of charging piles is used to charge the vehicle to be charged.

[0029] Each of the plurality of charging piles establishes a communication link with two adjacent charging piles arranged in a predetermined order, thereby forming a ring communication network.

[0030] The predetermined order includes a clockwise direction or a counterclockwise direction.

[0031] It is understandable that if Figure 1 As shown, in a charging station with 8 charging piles, starting from the charging pile numbered 1 in the lower right corner, in a clockwise direction, charging pile No. 1 is connected to charging pile No. 2, charging pile No. 2 is connected to charging pile No. 3, charging pile No. 3 is connected to charging pile No. 4, charging pile No. 4 is connected to charging pile No. 5, charging pile No. 5 is connected to charging pile No. 6, charging pile No. 6 is connected to charging pile No. 7, charging pile No. 7 is connected to charging pile No. 8, and charging pile No. 8 is connected to charging pile No. 1, thereby achieving a closed loop of information interaction between the charging piles.

[0032] A smart charging device based on blockchain connection is applied to a smart charging system based on blockchain connection, such as Figure 2 As shown, it includes a main control unit and a communication unit.

[0033] The main control unit is used to comprehensively control and coordinate the charging process.

[0034] The communication unit is used to establish a communication link with the communication units of two adjacent charging piles arranged in a predetermined order, so as to form a ring communication network.

[0035] The communication unit is also used to establish a Bluetooth connection with the vehicle to be charged.

[0036] It is understandable that the main control unit is used to comprehensively control and coordinate the charging process. Specifically, it is responsible for real-time monitoring of various working status parameters of the charging pile, such as voltage, current, power, etc., and accurately controlling the charging power and duration based on the preset charging strategy, so as to adapt to the battery characteristics and charging requirements of different vehicles to be charged; collecting, sorting and encrypting various data generated during the charging process, such as vehicle identification information, charging start and end time, charging power, etc., to ensure the integrity and security of the data; interacting with the vehicle's battery management system, receiving real-time status information of the vehicle battery, such as remaining power, battery temperature, etc., and dynamically adjusting the charging parameters based on this information; and, working in coordination with the communication unit, transmitting the processed data to adjacent charging piles and other related nodes in the blockchain network with the help of the communication unit, achieving data sharing and synchronization, and ensuring the efficient and stable operation of the entire charging system and trusted interaction based on blockchain.

[0037] It is understandable that the communication unit is used to establish a communication link with the communication units of two adjacent charging piles arranged in a predetermined order, so as to form a ring communication network. In addition, the communication unit is also used to establish a Bluetooth connection with the vehicle to be charged, so as to receive the charging request, battery information and other data sent by the vehicle, and send charging authorization, charging progress, estimated full time and other feedback information to the vehicle, maintain stable data interaction during the charging process, ensure smooth communication between the vehicle and the charging pile, provide strong support for intelligent charging services, and also lay the foundation for blockchain-based charging data recording and verification, and ensure the accurate transmission and storage of transaction information between vehicles, charging piles and blockchain networks.

[0038] It should be noted that the ring communication network can use a wired ring communication network or a wireless ring communication network.

[0039] The wired ring communication network includes Ethernet cables and optical fibers.

[0040] The wireless ring communication network includes WiFi, Bluetooth, ZigBee or other 2.4G frequency band networks.

[0041] It is understandable that the wired ring communication network usually uses Ethernet cables, optical fibers and other wired transmission media to connect the communication units of each charging pile. First, the stability of data transmission is extremely high, and it is not easily affected by external environmental factors such as electromagnetic interference and signal shielding, which can ensure that data is accurately and reliably transmitted between charging piles; second, the transmission speed is fast, which can meet the needs of rapid exchange of large amounts of data between charging piles; third, it has strong security, the wired network is relatively closed, and it is not easy to be illegally invaded by the outside world, which reduces the risk of data leakage and malicious tampering, and ensures the security and credibility of charging data based on blockchain.

[0042] It is understandable that the wireless ring communication network is constructed using WiFi, Bluetooth, ZigBee or other 2.4G frequency band wireless private network technologies. Compared with the wired ring network, firstly, there is no need for complex cable laying projects, and the network can be quickly established on the basis of existing charging pile facilities, which is especially suitable for scenarios where existing charging stations are upgraded to be intelligent. Secondly, it has strong scalability. When it is necessary to add new charging piles or adjust the network topology, the operation is relatively simple, which can effectively reduce the cost and time of system upgrades. Thirdly, the wireless communication network can realize seamless connection between charging piles and surrounding smart devices, such as data interaction with smart parking management systems, environmental monitoring equipment, etc., further expanding the intelligent functions of the charging system.

[0043] A smart charging method based on blockchain connection, applied to a smart charging system based on blockchain connection, see Figure 6As shown, the charging method comprises the following steps: Step S100: within a preset range, the charging pile obtains broadcast information of the vehicle to be charged.

[0044] In this step, the charging pile is any charging pile in the charging station; the charging pile periodically scans and obtains Bluetooth broadcast information data in the environment through a Bluetooth module.

[0045] It is understandable that if Figure 3 As shown, the vehicle to be charged will periodically broadcast its own identification code. When the vehicle to be charged enters a certain range of the charging station, any charging pile in the charging station monitors its broadcast information through the Bluetooth module of its communication unit. Once a broadcast signal that complies with the protocol is detected, it will receive and parse the broadcast information and extract key data, such as the vehicle's unique identification, current location, etc., for subsequent vehicle identification and processing procedures.

[0046] It is understandable that if Figure 3 As shown, for example, if charging pile No. 1 is within a preset range of 10 meters and detects that a vehicle to be charged has entered the charging area, it starts to obtain and parse the broadcast information of the vehicle to be charged.

[0047] In step S200, the charging pile determines whether the vehicle to be charged is a backup vehicle. If not, it is ignored; if so, it proceeds to step S300.

[0048] In this step, the backup vehicle refers to the vehicle to be charged being a registered charging vehicle or a pre-authorized vehicle in the charging station.

[0049] It is understandable that the charging station compares the received vehicle identification code with the locally stored list of registered or pre-authorized vehicles. This list can be updated synchronously from other charging stations or the management center through the blockchain network in the charging station, and contains the information of vehicles that are allowed to charge in this charging system. If the identification code matches successfully, it means that the vehicle is a rechargeable vehicle recognized by the system and continues to the subsequent steps; if it does not match, the vehicle broadcast information is ignored to avoid unnecessary processing of unauthorized vehicles and ensure the safety and standardization of the charging system.

[0050] Step S300: The charging pile sends the entry information of the vehicle to be charged to other charging piles through blockchain transmission.

[0051] In this step, the entry information refers to the information recognized by the charging pile when the vehicle to be charged enters the preset range.

[0052] The entry information includes a vehicle identification code, an entry time and a current location.

[0053] It is understandable that by using the distributed ledger technology of blockchain, the entry information of the vehicle to be charged, such as the vehicle identification code, entry time, current location and other data, is encrypted to form a transaction information record. Then, according to the consensus algorithm of the blockchain network, the transaction information is broadcast to other charging pile nodes in the entire charging network. After receiving the information, other charging pile nodes verify it. If the verification is successful, the information is recorded in their respective local ledgers to achieve synchronous sharing of information, ensuring that all charging piles know that a vehicle has entered the system and where it has entered, so as to facilitate subsequent collaborative processing.

[0054] It is understandable that if Figure 3 As shown, assuming that after charging pile No. 1 obtains the entry information of the vehicle to be charged, charging pile No. 1 sends the entry information to charging pile No. 2 and charging pile No. 8 respectively, then charging pile No. 2 sends the entry information to charging pile No. 3, and charging pile No. 8 sends the entry information to charging pile No. 7, then charging pile No. 3 sends the entry information to charging pile No. 4, and charging pile No. 7 sends the entry information to charging pile No. 6, then charging pile No. 4 or charging pile No. 6 sends the entry information to charging pile No. 5. In this way, charging piles No. 1 to No. 8 know that the vehicle to be charged has entered the charging area and is ready to be charged.

[0055] It is understandable that the current location information can be calculated by the charging pile through Bluetooth ranging, including RSSI ranging, Bluetooth channel ranging, AOA ranging and AOD ranging.

[0056] Step S400: Based on the entry information, each charging post in the charging station measures the distance between the vehicle to be charged and itself.

[0057] In this step, the measurement method includes any one of RSSI ranging, Bluetooth 6.0 channel ranging, AOA ranging and AOD ranging.

[0058] It is understandable that, for example, based on the channel detection method of Bluetooth 6.0, each charging pile in the charging station measures the location information of the vehicle to be charged and itself, and uses the channel ranging algorithm of PBR and RTT to calculate the straight-line distance between itself and the vehicle to be charged. In the calculation process, the influence of positioning error needs to be considered, and appropriate error correction processing needs to be performed to improve the accuracy of distance measurement and provide a reliable data basis for subsequent distance bidding.

[0059] It is understandable that if Figure 4 As shown, each charging pile measures the distance to the vehicle, which is helpful to further quickly determine which charging pile is connected to the vehicle to be charged by Bluetooth.

[0060] It should be noted that if all the charging piles in the charging station detect that the vehicle to be charged is not within the preset range, all the charging piles in the charging station stop measuring the distance to the vehicle to be charged.

[0061] It is understandable that if Figure 4 As shown, when each charging pile calculates that the distance between the vehicle to be charged and itself exceeds the preset range of 10 meters, it exits the distance measurement between itself and the vehicle to be charged.

[0062] It is understandable that when the vehicle to be charged re-enters the preset 10-meter range of any charging pile in the charging station, the charging pile re-enters step S100.

[0063] Step S500: Each charging pile informs other charging piles of the distance information between itself and the vehicle to be charged through blockchain transmission.

[0064] It is understandable that, similar to step S300, each charging pile encrypts the distance data between itself and the vehicle to be charged and constructs blockchain transaction information. With the help of the blockchain broadcast mechanism, this transaction information is propagated to other charging pile nodes in the network. After receiving and verifying the information, other nodes update the local data record of the distance relationship between the vehicle to be charged and each charging pile, so that the entire charging network can fully grasp the distance between each charging pile and the vehicle, providing a basis for determining the most suitable charging service provider.

[0065] It is understandable that if Figure 4 As shown, it is assumed that when the vehicle to be charged moves in front of charging pile No. 2, the distance between the vehicle and charging pile No. 1 is 5 meters, 3 meters from charging pile No. 2, 5 meters from charging pile No. 3, 7 meters from charging pile No. 4, 8 meters from charging pile No. 5, 6 meters from charging pile No. 6, 4 meters from charging pile No. 7, and 6 meters from charging pile No. 8. At the current moment, each charging pile sends the distance between itself and the vehicle to be charged to other charging piles in the charging station through the blockchain. When the vehicle to be charged moves to charging pile No. 3, the same applies.

[0066] Step S600, through distance bidding, the charging pile closest to the vehicle to be charged establishes a Bluetooth connection with the vehicle to be charged, and realizes information exchange.

[0067] In this step, the intercommunication information includes vehicle battery information, commonly used charging pile status information and other charging pile status information.

[0068] It can be understood that the distance bidding is an algorithm protocol pre-implanted in each charging pile. After knowing the distance relationship between all charging piles in the blockchain and the vehicles to be charged, the charging piles each execute the corresponding strategy.

[0069] It is understandable that, according to the data information transmitted by the blockchain, each charging pile has its own distance from the vehicle to be charged, as well as the distance between other charging piles and the vehicle to be charged. According to the preset agreement, the charging pile closest to the vehicle to be charged can be connected to the vehicle to be charged by Bluetooth. After the connection is established, the two parties conduct handshake communication and exchange information such as encryption keys and communication protocol versions to ensure the security and compatibility of subsequent information interaction and achieve stable intercommunication information, including vehicle battery information, commonly used charging pile information and current charging pile status information exchange.

[0070] It is understandable that if Figure 4 As shown, it is assumed that when the vehicle to be charged moves in front of charging pile No. 2, the distance between the vehicle and charging pile No. 1 is 5 meters, 3 meters from charging pile No. 2, 5 meters from charging pile No. 3, 7 meters from charging pile No. 4, 8 meters from charging pile No. 5, 6 meters from charging pile No. 6, 4 meters from charging pile No. 7, and 6 meters from charging pile No. 8. At the current moment, each charging pile sends the distance between itself and the vehicle to be charged to other charging piles in the charging station through the blockchain. Each charging pile knows that the distance between charging pile No. 2 and the vehicle to be charged is the shortest. Therefore, charging pile No. 2 automatically connects to the vehicle to be charged through Bluetooth, and other charging piles refuse to connect to the vehicle to be charged through Bluetooth. Similarly, when the vehicle to be charged moves in front of charging pile No. 3, charging pile No. 2 automatically disconnects the Bluetooth connection with the vehicle to be charged, charging pile No. 3 automatically disconnects the Bluetooth connection with the vehicle to be charged, and other charging piles refuse to connect to the vehicle to be charged through Bluetooth.

[0071] It should be noted that the status information of the commonly used charging piles and the status information of the other charging piles can be displayed through the vehicle computer of the vehicle to be charged.

[0072] It is understandable that, assuming that the user frequently uses charging piles No. 2 and No. 3, when the charging piles establish a Bluetooth connection with the vehicle to be charged, the car computer on the vehicle to be charged can highlight the current status of charging piles No. 2 and No. 3, including the status of being in use, idle and faulty.

[0073] It is understandable that, assuming that charging piles No. 7 and No. 8 are currently faulty, the car computer on the vehicle to be charged can highlight the fault status of charging piles No. 7 and No. 8, prompting the vehicle not to go there to avoid wasting time and energy.

[0074] In this way, the charging efficiency of the vehicle to be charged can be effectively improved based on the commonly used charging pile status information and other charging pile status information.

[0075] Step S700: The charging pile closest to the vehicle to be charged obtains data information of the vehicle to be charged, and informs other charging piles of the data information through blockchain transmission.

[0076] In this step, the data information includes the remaining battery power, battery type, battery health status, vehicle charging history and charging cover status.

[0077] The charging cover state includes a charging cover open state and a charging cover closed state.

[0078] It is understandable that the connected charging pile sends a data request instruction to the vehicle to be charged, and the vehicle responds and sends detailed data information, such as the remaining battery power, battery type, battery health, vehicle charging history, etc. to the charging pile. After receiving this data, the charging pile uses blockchain technology again to encrypt and package the data into transaction information and spread it to other charging pile nodes. Other nodes receive and store this data so that they can perform data analysis, fault diagnosis, or charging strategy optimization when needed, while also ensuring the consistency and traceability of data in the entire charging network.

[0079] It is understandable that no matter the vehicle to be charged is charged at another charging pile next time, or is charged at a different charging pile midway during the current charge, each charging pile can accurately know the specific or real-time information of the vehicle to be charged.

[0080] Step S800, whether the data information of the vehicle to be charged includes the charging cover opening status information of the vehicle to be charged, if not, return to step S700; if yes, enter step S900.

[0081] In this step, the information on the opening state of the charging cover of the vehicle to be charged is a type of the charging cover state information.

[0082] It is understandable that the charging pile analyzes the received data information of the vehicle to be charged to check whether it contains a specific identification or status information indicating that the charging cover is open. If the information is not detected, the charging pile continues to maintain communication with the vehicle and re-acquires the vehicle data information regularly or according to the set conditions to wait for the update of the charging cover opening status; if the charging cover is detected to be open, it indicates that the vehicle is ready to receive charging services and can enter the next step to start the charging process.

[0083] It is understandable that if Figure 5As shown in the figure, when the vehicle to be charged stops in front of charging pile No. 2, the vehicle to be charged establishes a Bluetooth connection with charging pile No. 2. According to Bluetooth communication, the two parties exchange their information every 10ms. At this time, when the user opens the charging cover, charging pile No. 2 obtains the information that the vehicle to be charged has opened the charging cover, indicating that the user is ready to use charging pile No. 2 to charge the vehicle to be charged. Therefore, charging pile No. 2 starts the charging power in advance, and when the user connects the charging connector, it can quickly enter the charging state.

[0084] Step S900, starting the charging power of the charging pile closest to the vehicle to be charged.

[0085] In this step, before starting the charging power, the charging pile closest to the vehicle to be charged needs to formulate a charging strategy based on the battery information of the vehicle.

[0086] It is understandable that, based on the vehicle's battery information and the pre-set charging strategy, the charging pile closest to the vehicle to be charged calculates the appropriate initial charging power. For example, for vehicles with low power and batteries that allow fast charging, a higher initial charging power can be set, but at the same time, the power output limit of the charging pile itself and the grid load must be considered. Before starting the charging power, the charging pile also needs to perform a series of self-test operations, such as checking whether the charging line connection is normal and whether the charging gun is working properly, to ensure the safety of the charging process. If the self-test passes, a start command is sent to the charging module to start outputting the set charging power.

[0087] It is understandable that the detection device and switch are built into the charging gun. After the charging pile starts the power, when the detection device does not detect that the charging head is connected to the charging port of the vehicle to be charged, the switch is turned on and the power current is injected into the ground wire; when the detection device detects that the charging head is connected to the charging port of the vehicle to be charged, the switch is turned on and the power current is injected into the vehicle to be charged. In this way, safety accidents can be effectively avoided.

[0088] It is understandable that compared with the original charging method, users need to park the car in front of the charging pile, connect the vehicle to be charged to the charging connector, and then scan the code with the mobile phone to obtain the status information of the charging pile to verify whether the charging pile is normal. After a series of complicated payment processes, the charging pile will start scanning the information of the vehicle to be charged, formulate corresponding charging strategies, and finally start the corresponding charging power.

[0089] Therefore, the traditional charging process and method are not conducive to the efficiency of user charging operation, and reduce the user's charging experience.

[0090] Step S1000, within a preset time threshold, detect whether the vehicle to be charged is plugged into a charging head, if not, proceed to step S1200; if yes, proceed to step S1100.

[0091] It is understandable that after starting the charging power, the charging pile starts timing and waits for the vehicle to be plugged into the charging head. The preset time threshold can be set according to actual conditions, such as 2 minutes. During the waiting period, the charging pile continuously monitors the connection status of the charging gun, and detects the voltage and current changes or specific connection sensing signals at the charging gun interface through another detection path of the detection device to determine whether the charging head is inserted. If the charging head is detected to be inserted within the specified time, the normal charging process is entered; if the charging head is still not detected after the time threshold, it is considered that the charging process is abnormal, which may be an operational error or other fault on the vehicle side, and the next step is entered for processing.

[0092] It is understandable that the detection device and switch are built into the charging gun. After the charging pile starts the power, when the detection device does not detect that the charging head is connected to the charging port of the vehicle to be charged, the switch is turned on and the power current is injected into the ground wire; when the detection device detects that the charging head is connected to the charging port of the vehicle to be charged, the switch is turned on and the power current is injected into the vehicle to be charged. In this way, safety accidents can be effectively avoided.

[0093] Step S1100, the charging pile closest to the vehicle to be charged charges the vehicle to be charged until charging is completed.

[0094] It is understandable that after the charging head is inserted, the charging pile maintains close communication with the vehicle's battery management system. The charging pile monitors the charging current, voltage, power and other parameters in real time, and dynamically adjusts the charging power according to the feedback information of the vehicle battery, such as battery temperature, voltage change, etc., to ensure the safety and efficiency of the charging process. At the same time, the charging pile transmits the data information of the charging process, such as charging power, charging time, real-time power, etc., to other charging pile nodes through the blockchain at certain time intervals for recording and backup. When the vehicle battery is fully charged, the charging pile stops charging output and sends a charging completion notification to the vehicle. At the same time, the final charging data information is fully recorded in the blockchain network for subsequent billing, statistical analysis, and troubleshooting.

[0095] It can be understood that a detection device and a switch are built into the charging gun muzzle. After the charging pile starts the power, when the detection device detects that the charging head is connected to the charging port of the vehicle to be charged, the switch is turned on and the power current is injected into the vehicle to be charged.

[0096] Step S1200, stop starting the charging power until manual intervention is performed.

[0097] It is understandable that since the charging head is not detected to be inserted within the preset time, the charging pile stops the currently started charging power output to avoid energy waste and potential safety risks. At the same time, the charging pile will record the abnormal event information locally, including the vehicle identification code, time, abnormal cause, etc., and transmit the information to other charging pile nodes and the management center through the blockchain network. At this time, the charging pile enters a waiting state until it receives a manual intervention instruction, such as the operation and maintenance personnel conduct an on-site inspection and manually start the charging process, or the remote management personnel send a restart instruction through the monitoring system, and then try to charge again.

[0098] It can be understood that a detection device and a switch are built into the charging gun muzzle. After the charging pile starts the power, when the detection device does not detect that the charging head is connected to the charging port of the vehicle to be charged, the switch is turned on and the power current is injected into the ground wire.
