Description

Technical Field

[0001] The present invention relates to the technical field of blockchain connection, and particularly relates to an intelligent charging device, system and charging method based on blockchain connection. Background Art

[0002] With the wide popularization of electric vehicles, the convenience and efficiency of charging facilities have increasingly become the key concerns in the industry development. In the 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 program after parking. This process is not only cumbersome, but also requires users to operate precisely. Moreover, in the case of poor network signal or damaged or blurred QR codes, it is extremely easy to cause the charging start to fail, wasting a lot of time and energy of users.

[0004] A more prominent problem is the poor maintenance condition of charging piles. Due to the lack of an effective real-time monitoring and early warning mechanism, users often encounter multiple damaged charging piles continuously. These damaged charging piles may have problems such as charging interface failures, abnormal power transmission, or internal circuit short circuits, resulting in the inability to charge electric vehicles normally. Users have to try one by one to find available charging piles, which greatly affects the charging efficiency, significantly extends the original short charging waiting time of users, and seriously reduces the user experience.

[0005] Moreover, there are obvious lags and opaqueness in the information interaction between users, charging piles and charging station operators in the existing charging system. It is difficult for users to know in advance the real-time working status of each charging pile in the charging station, and the operator cannot obtain the fault information of the charging pile in time for rapid repair, further exacerbating the waste of charging resources and the inconvenience of use.

[0006] In summary, the existing electric vehicle charging mode urgently needs an innovative solution that can simplify the charging operation process, real-time monitor the status of charging piles and achieve efficient information interaction to improve charging efficiency and user satisfaction. The emergence of the intelligent charging device, system and charging method 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.

[0025] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more unless otherwise specifically defined.

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

[0027] Next, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] The present invention will be specifically described below with reference to the drawings:

[0029] An intelligent charging system based on blockchain connection, as Figure 1 shown, includes a plurality of charging piles and vehicles to be charged.

[0030] Any one of the plurality of charging piles is used to charge the vehicle to be charged.

[0031] Each of the plurality of charging piles establishes a communication link with the adjacent two charging piles arranged in a predetermined order to form a ring-shaped communication network.

[0032] The predetermined order includes the clockwise direction or the counterclockwise direction.

[0033] It is understandable that, as Figure 1 shown, in a charging station with 8 charging piles, starting from the charging pile numbered 1 in the lower right corner and moving in a clockwise direction, the charging pile numbered 1 is communicatively connected to the charging pile numbered 2, the charging pile numbered 2 is communicatively connected to the charging pile numbered 3, the charging pile numbered 3 is communicatively connected to the charging pile numbered 4, the charging pile numbered 4 is communicatively connected to the charging pile numbered 5, the charging pile numbered 5 is communicatively connected to the charging pile numbered 6, the charging pile numbered 6 is communicatively connected to the charging pile numbered 7, the charging pile numbered 7 is communicatively connected to the charging pile numbered 8, and the charging pile numbered 8 is communicatively connected to the charging pile numbered 1 again, thereby achieving a closed-loop information interaction among the charging piles.

[0034] An intelligent charging device based on blockchain connection is applied to an intelligent charging system based on blockchain connection, as Figure 2 shown, and includes a main control unit and a communication unit.

[0035] The main control unit is used to comprehensively manage and coordinate the charging process.

[0036] The communication unit is used to establish a communication link with the communication units of two adjacent charging piles arranged in a predetermined order, thereby forming a ring-shaped communication network.

[0037] The communication unit is also used to establish a Bluetooth connection with the vehicle to be charged.

[0038] It is understandable that the main control unit is used to comprehensively manage and coordinate the charging process. Specifically, it is responsible for real-time monitoring of various working state parameters of the charging pile, such as voltage, current, power, etc., accurately controlling the charging power and duration based on a 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 times, charging power, etc., to ensure the integrity and security of the data; interacting with the battery management system of the vehicle, receiving real-time state information of the vehicle battery, such as remaining power, battery temperature, etc., and dynamically adjusting the charging parameters according to this information; and, cooperating with the communication unit to transmit the processed data to adjacent charging piles and other relevant nodes in the blockchain network through the communication unit, achieving data sharing and synchronization, and ensuring the efficient and stable operation of the entire charging system and the trustworthy interaction based on the blockchain.

[0039] It can be understood 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, thereby forming 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 data such as charging requests and battery information sent by the vehicle end, and send feedback information such as charging authorization, charging progress, and estimated full charge time to the vehicle, maintaining stable data interaction during the charging process, ensuring smooth communication between the vehicle and the charging pile, providing strong support for intelligent charging services, and at the same time laying a foundation for blockchain-based charging data recording and verification, ensuring the accurate transmission and storage of transaction information between the vehicle, the charging pile, and the blockchain network.

[0040] It should be noted that the ring communication network can use a wired ring communication network or a wireless ring communication network.

[0041] The wired ring communication network includes Ethernet cables and optical fibers.

[0042] The wireless ring communication network includes WiFi, Bluetooth, ZigBee, or other 2.4G frequency band networks.

[0043] It can be understood that the wired ring communication network usually uses wired transmission media such as Ethernet cables and optical fibers to connect the communication units of each charging pile. First, the stability of data transmission is extremely high, not easily affected by external environmental factors such as electromagnetic interference and signal blockage, and can ensure accurate and reliable data transmission between each charging pile; second, the transmission speed is fast, which can meet the rapid exchange needs of a large amount of data between charging piles; third, the security is strong. The wired network is relatively closed and not easily illegally invaded from the outside, reducing the risk of data leakage and malicious tampering, and ensuring the security and credibility of blockchain-based charging data.

[0044] It can be understood that the wireless ring communication network is constructed using wireless private network technologies such as WiFi, Bluetooth, ZigBee, or other 2.4G frequency bands. Compared with the wired ring network, first, there is no need to carry out complex cable laying projects, and it can quickly form a network on the basis of existing charging pile facilities, especially suitable for the scenario of intelligent upgrading and transformation of existing charging stations. Second, it has strong scalability. When new charging piles need to be added or the network topology needs to be adjusted, the operation is relatively simple, which can effectively reduce the cost and time of system upgrading. Third, the wireless communication network can achieve seamless connection between the charging pile and surrounding intelligent devices, such as data interaction with the intelligent parking lot management system, environmental monitoring equipment, etc., further expanding the intelligent functions of the charging system.

[0045] An intelligent charging method based on blockchain connection is applied to an intelligent charging system based on blockchain connection. See Figure 6As shown, the charging method includes the following steps:

[0046] Step S100, within a preset range, the charging pile acquires the broadcast information of the vehicle to be charged.

[0047] In this step, the charging pile is any one of the charging piles in the charging station; the charging pile scans and acquires the Bluetooth broadcast information data in the environment at regular intervals through the Bluetooth module.

[0048] It can be understood that, as Figure 3 shown, the vehicle to be charged broadcasts its identification code periodically. When the vehicle to be charged enters a certain range of the charging station. Any one of the charging piles in the charging station listens to its broadcast information through the Bluetooth module of its communication unit. Once a broadcast signal that conforms to the protocol is detected, it receives and analyzes the broadcast information, extracts the key data therein, such as the vehicle unique identifier, current position, etc., for subsequent vehicle identity recognition and processing procedures.

[0049] It can be understood that, as Figure 3 shown, for example, when Charging Pile No. 1 acquires that the vehicle to be charged has entered the charging area within the preset 10-meter range, it starts to acquire and analyze the broadcast information of the vehicle to be charged.

[0050] Step S200, the charging pile determines whether the vehicle to be charged is a backup vehicle. If not, it ignores it; if so, it proceeds to Step S300.

[0051] In this step, the backup vehicle refers to that the vehicle to be charged is a registered charging vehicle or a pre-authorized vehicle in the charging station.

[0052] It can be understood that the charging pile compares the received vehicle identification code with the list of registered or pre-authorized vehicles stored locally. This list can be synchronized and updated from other charging piles or the management center through the blockchain network in the charging station and contains the vehicle information allowed to charge in this charging system. If the identification code matches successfully, it indicates that the vehicle is a rechargeable vehicle recognized by the system, and the subsequent steps are continued; if not, the vehicle broadcast information is ignored to avoid unnecessary processing of unauthorized vehicles and ensure the security and standardization of the charging system.

[0053] Step S300, through the blockchain transmission method, the charging pile sends the entry information of the vehicle to be charged to other charging piles.

[0054] In this step, the entry information refers to the information identified by the charging pile when the vehicle to be charged enters the preset range.

[0055] The entry information includes the vehicle identification code, entry time, and current location.

[0056] It is understandable that by using the distributed ledger technology of the blockchain, after encrypting the entry information of the vehicle to be charged, such as vehicle identification code, entry time, current location, etc., a transaction information record is formed. 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 passes, the information is recorded in their respective local ledgers, realizing the synchronous sharing of information and ensuring that all charging piles know that a vehicle has entered the system and where it entered, so as to facilitate subsequent collaborative processing.

[0057] It is understandable that as Figure 3 shown, assuming that 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. Subsequently, 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. Subsequently, 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. Subsequently, 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 all know that the vehicle to be charged has entered the charging area and is ready to be charged.

[0058] It is understandable that the information of the current location can be measured by the charging pile through Bluetooth ranging, including any one of RSSI ranging, Bluetooth channel ranging, AOA ranging, and AOD ranging.

[0059] Step S400, based on the entry information, each charging pile in the charging station measures the distance between the vehicle to be charged and itself.

[0060] In this step, the measurement method includes any one of RSSI ranging, Bluetooth 6.0 channel ranging, AOA ranging, and AOD ranging.

[0061] 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 position information between itself and the vehicle to be charged, and uses the channel ranging algorithms of PBR and RTT to calculate the straight-line distance between itself and the vehicle to be charged. During the calculation process, the influence of positioning error needs to be considered and appropriate error correction processing is carried out to improve the accuracy of distance measurement and provide a reliable data basis for subsequent distance bidding.

[0062] It is understandable that as Figure 4 shown, each charging pile measures the distance from the vehicle, which is conducive to further quickly determining which charging pile will establish a Bluetooth connection with the vehicle to be charged.

[0063] 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, then all the charging piles in the charging station will stop calculating the distance to the vehicle to be charged.

[0064] It can be understood that as Figure 4 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 calculation between itself and the vehicle to be charged.

[0065] It can be understood that when the vehicle to be charged re-enters the preset 10-meter range of any charging pile in the charging station, that charging pile re-enters step S100.

[0066] Step S500: In the way of blockchain transmission, each charging pile informs other charging piles of the distance information between itself and the vehicle to be charged.

[0067] It can be understood that similar to step S300, each charging pile encrypts the calculated distance data between itself and the vehicle to be charged and constructs blockchain transaction information. With the help of the broadcast mechanism of the blockchain, this transaction information is spread to other charging pile nodes in the network. After other nodes receive and verify the information, they update the local data records on the distance relationship between the vehicle to be charged and each charging pile, enabling the entire charging network to comprehensively grasp the distance status between each charging pile and the vehicle, providing a basis for determining the most suitable charging service provider.

[0068] It can be understood that as Figure 4 shown, assume that when the vehicle to be charged moves in front of the No. 2 charging pile, the measured distances between the vehicle and the No. 1 charging pile is 5 meters, the No. 2 charging pile is 3 meters, the No. 3 charging pile is 5 meters, the No. 4 charging pile is 7 meters, the No. 5 charging pile is 8 meters, the No. 6 charging pile is 6 meters, the No. 7 charging pile is 4 meters, and the No. 8 charging pile is 6 meters. 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 the No. 3 charging pile, the same principle applies.

[0069] Step S600: Through distance bidding, the charging pile with the shortest distance to the vehicle to be charged establishes a Bluetooth connection with the vehicle to be charged and realizes information intercommunication.

[0070] In this step, the information intercommunication includes vehicle battery information, the status information of the frequently used charging pile, and the status information of other charging piles.

[0071] It can be understood that the distance-based bidding is an algorithm agreement pre-implanted in each charging pile. After learning the distance relationships between all charging piles in the blockchain for the vehicle to be charged, each charging pile executes its corresponding strategy.

[0072] It can be understood 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 distances between other charging piles and the vehicle to be charged. According to the preset agreement, the charging pile with the shortest distance to the vehicle to be charged can establish a Bluetooth connection with the vehicle to be charged. 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 information exchange, including the exchange of vehicle battery information, frequently used charging pile information, and the current status information of the current charging pile.

[0073] It can be understood that as Figure 4 shown, assume that when the vehicle to be charged moves in front of the No. 2 charging pile, the measured distance between the vehicle and the No. 1 charging pile is 5 meters, the distance to the No. 2 charging pile is 3 meters, the distance to the No. 3 charging pile is 5 meters, the distance to the No. 4 charging pile is 7 meters, the distance to the No. 5 charging pile is 8 meters, the distance to the No. 6 charging pile is 6 meters, the distance to the No. 7 charging pile is 4 meters, and the distance to the No. 8 charging pile is 6 meters. At the current moment, each charging pile sends its own distance from the vehicle to be charged to other charging piles in the charging station through the blockchain. Each charging pile knows that the No. 2 charging pile has the shortest distance to the vehicle to be charged. Therefore, the No. 2 charging pile automatically establishes a Bluetooth connection with the vehicle to be charged, and other charging piles refuse to establish a Bluetooth connection with the vehicle to be charged. Similarly, when the vehicle to be charged moves in front of the No. 3 charging pile, the No. 2 charging pile automatically disconnects the Bluetooth connection with the vehicle to be charged, the No. 3 charging pile automatically disconnects the Bluetooth connection with the vehicle to be charged, and other charging piles refuse to establish a Bluetooth connection with the vehicle to be charged.

[0074] It should be noted that the frequently used charging pile status information and the status information of other charging piles can be displayed on the in-vehicle computer of the vehicle to be charged.

[0075] It can be understood that assume that the user frequently uses the No. 2 and No. 3 charging piles. When the charging pile establishes a Bluetooth connection with the vehicle to be charged, the current status of the No. 2 and No. 3 charging piles, including the in-use, idle, and faulty statuses, can be prominently prompted on the in-vehicle computer of the vehicle to be charged.

[0076] It can be understood that assume that the No. 7 and No. 8 charging piles are currently faulty. Then, the faulty statuses of the No. 7 and No. 8 charging piles can be prominently prompted on the in-vehicle computer of the vehicle to be charged, prompting not to go there to avoid wasting time and energy.

[0077] In this way, according to the frequently used charging pile status information and the status information of other charging piles, the charging efficiency of the vehicle to be charged can be effectively improved.

[0078] Step S700: The charging pile closest to the vehicle to be charged obtains the data information of the vehicle to be charged and, through blockchain transmission, notifies other charging piles of the data information.

[0079] In this step, the data information includes the remaining battery power, battery type, battery health status, vehicle charging history, and charging cover status.

[0080] The charging cover status includes the charging cover open state and the charging cover closed state.

[0081] It can be understood that the established charging pile sends a data request command to the vehicle to be charged. After the vehicle responds, it sends detailed data information, such as the remaining battery power, battery type, battery health status, vehicle charging history, etc., to the charging pile. After receiving these 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 these data for operations such as data analysis, fault diagnosis, or charging strategy optimization when needed, while also ensuring the consistency and traceability of the data in the entire charging network.

[0082] It can be understood that whether the vehicle to be charged charges at another charging pile next time or changes the charging pile during this charging process, each charging pile can accurately know the specific or real-time information of the vehicle to be charged.

[0083] Step S800: Whether the data information of the vehicle to be charged includes the information on the open state of the charging cover of the vehicle to be charged. If not, return to step S700; if so, enter step S900.

[0084] In this step, the information on the open state of the charging cover of the vehicle to be charged is one type of the charging cover status information.

[0085] It can be understood that the charging pile parses the received data information of the vehicle to be charged and checks whether it contains a specific identifier or status information indicating that the charging cover is open. If this information is not detected, it continues to maintain a communication connection with the vehicle and regularly or according to set conditions re-obtains the vehicle data information to wait for the update of the open state of the charging cover; if it detects that the charging cover is open, it indicates that the vehicle is ready to receive charging services and can enter the next step to start the charging process.

[0086] It can be understood that as Figure 5As shown in the figure, when the vehicle to be charged stops in front of Charging Pile No. 2 and a Bluetooth connection is established between the vehicle to be charged and Charging Pile No. 2, according to Bluetooth communication, both parties exchange their own information every 10 ms. At this time, when the user opens the charging cover, Charging Pile No. 2 obtains the information that the charging cover of the vehicle to be charged is opened, 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, so that when the user connects the charging connector, it can quickly enter the charging state.

[0087] Step S900: The charging pile closest to the vehicle to be charged starts the charging power.

[0088] In this step, before starting the charging power, the charging pile closest to the vehicle to be charged needs to formulate a charging strategy according to the battery information of the vehicle.

[0089] It can be understood that according to the battery information of the vehicle and the preset charging strategy, the charging pile closest to the vehicle to be charged calculates an appropriate initial charging power. For example, for a vehicle with a low battery level and a battery that allows 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 situation need to be considered. Before starting the charging power, the charging pile also needs to perform a series of self-check 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-check passes, a start command is sent to the charging module to start outputting the set charging power.

[0090] 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 opened 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 opened and the power current is injected into the vehicle to be charged. In this way, safety accidents can be effectively avoided.

[0091] It can be understood that compared with the original charging method, the user needs to park the car in front of the charging pile. After connecting the charging connector to the vehicle to be charged, then obtain the status information of the charging pile by scanning the code with the mobile phone, verify whether the charging pile is normal, and then go through a series of complex payment processes before the charging pile starts to scan the information of the vehicle to be charged, formulate a corresponding charging strategy, and finally start the corresponding charging power.

[0092] Therefore, the traditional charging process and method are very unfavorable to the charging efficiency of the user and reduce the user experience of charging operation.

[0093] Step S1000: Detect whether the charging head is inserted into the vehicle to be charged within a preset time threshold. If not, go to step S1200; if so, go to step S1100.

[0094] 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.

[0095] 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.

[0096] Step S1100, the charging pile closest to the vehicle to be charged charges the vehicle to be charged until charging is completed.

[0097] 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.

[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 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.

[0099] Step S1200, stop starting the charging power until manual intervention is performed.

[0100] It is understandable that since the charging head is not detected within the preset time, the charging pile stops the output of the currently started charging power, avoiding power waste and potential safety risks. At the same time, the charging pile records the information of this abnormal event locally, including the vehicle identification code, time, reason for the abnormality, etc., and spreads this information to other charging pile nodes and the management center through the blockchain network. At this time, the charging pile enters the waiting state until it receives a manual intervention instruction, such as when the operation and maintenance personnel conduct on-site inspections and manually start the charging process, or when the remote management personnel send a restart instruction through the monitoring system, will it attempt to perform the charging operation again.

[0101] It is understandable that a detection device and a switch are built into the charging gun nozzle. 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.
