Description

Technical Field

[0001] This invention relates to the field of blockchain technology applications in electric vehicles, specifically to a blockchain-based energy interaction method, platform, system, device, and medium. Background Technology

[0002] With the rapid development of electric vehicle technology, electric vehicles, in addition to being a means of transportation, possess unique spatiotemporal characteristics that endow them with diversified roles and functions. As charging and discharging entities, electric vehicles can interact with multiple other entities (mobile phones, electrical appliances, other electric vehicles, and the power grid). Utilizing electric vehicles as mobile energy storage units to meet diverse energy needs is one of their important functions. However, the process of energy interaction between electric vehicles and other electricity consumers involves many uncertainties, making it difficult for these entities to quickly achieve interactive matching. Furthermore, with the diversification of energy interaction entities, the interaction becomes increasingly complex. The energy transfer process between unfamiliar entities often struggles to establish a shared trust mechanism. Moreover, due to losses during energy storage and use, in unequal evaluation mechanisms and centralized systems, it is difficult to achieve efficient interaction modes among the energy interaction entities, and there is also a risk of data tampering between entities.

[0003] Blockchain is a novel application model of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanisms, and encryption algorithms. It features decentralization, immutability, full traceability, accountability, collective maintenance, and transparency. Blockchain's most fundamental capability is solving the problem of information asymmetry, enabling collaborative trust and unified action among multiple entities. Applying blockchain technology to energy interaction in electric vehicles leverages its transparency and immutability to address issues of information mismatch and unfair energy trading, effectively preventing the tampering of transaction information. However, current technologies merely implement information recording and management on the blockchain, or focus on using blockchain for transactions, settlements, or recording functions, failing to achieve flexible energy management and diverse interactions.

[0085] S3. Obtain confirmation information from the terminal; wherein the confirmation information is determined by the terminal based on the published power information and energy transmission data. Before performing step S1 of this invention, which involves determining the mobile power supply entity providing the transaction service and completing the handshake, the process includes:

[0086] The blockchain platform obtains the charging level and current power level of the mobile power supply unit after charging is completed, and records the information on the blockchain.

[0087] The blockchain platform obtains the power supply capacity and price range of mobile power supply entities released by the terminals;

[0088] The power supply price range is selected and determined by the mobile power supply entity based on a pre-determined power supply price, and the power supply price is determined by a consensus mechanism for charging and discharging energy.

[0089] The determination of the power supply price in this invention includes:

[0090] The blockchain platform uses a pre-trained battery charging and discharging model of the power supply entity to rate the charging and discharging status of the battery of the mobile power supply entity.

[0095] Step S1 of the present invention can be implemented in at least two ways. One way is that the power user selects the mobile power supply unit at the terminal, and the process is as follows:

[0096] The blockchain platform obtains the electricity consumption information and electricity demand of the electricity users published by the terminal, and completes on-chain accounting based on the electricity consumption information of the electricity users.

[0097] The blockchain platform obtains the mobile power supply provider selected by the electricity user based on the terminal.

[0098] The blockchain platform will publish the electricity users and mobile power supply entities involved in this transaction service, and complete the handshake between the electricity users and mobile power supply entities.

[0099] Step S1 of the present invention can also be based on blockchain recommendation, the process of which is as follows:

[0100] The blockchain platform obtains the electricity consumption information and electricity demand of the electricity users published by the terminal, and completes on-chain accounting based on the electricity consumption information of the electricity users.

[0101] The blockchain platform broadcasts the electricity demand published by the terminal on the blockchain and selects an electricity price range from the pre-determined electricity prices;

[0102] The blockchain platform recommends mobile power providers to offer services for this transaction based on the electricity demand and price range.

[0103] The blockchain platform will publish the electricity users and mobile power supply entities involved in this transaction service and complete the handshake between the electricity users and mobile power supply entities;

[0104] The electricity price is determined by a consensus mechanism for charging and discharging energy. The determination of the electricity price in this invention includes:

[0105] The blockchain platform assesses the energy consumption loss of the electricity users based on a pre-trained energy loss model and determines the status level of each electricity user based on the assessment results.

[0106] The blockchain platform determines electricity prices based on the aforementioned status levels;

[0107] The training of the energy loss model includes: training it using a neural network prediction algorithm based on the historical transaction data of each electricity user. The historical transaction data of the electricity user includes: electricity user type, historical charging performance of the electricity user, and the service life of the electricity user.

[0108] In this invention, the blockchain platform recommends mobile power supply providers for this transaction based on the electricity demand and electricity price range, including:

[0109] The blockchain platform makes recommendations based on the electricity demand and price range, as well as the status level and price range of each mobile power supply entity.

[0110] Step S2 of the present invention includes:

[0111] The blockchain platform obtains the electricity information of the mobile power supply entity and the electricity consumption entity after the energy interaction is completed, and records it on the chain;

[0112] The blockchain platform calculates the discharge amount of the mobile power supply entity, the charging amount of the power consumption entity, the lost amount of electricity, and the payer of the lost amount of electricity based on the electricity information of the mobile power supply entity before the completion of the energy interaction, the electricity information of the mobile power supply entity after the completion of the energy interaction, the electricity information of the power consumption entity before the completion of the energy interaction, and the electricity information of the power consumption entity after the completion of the energy interaction.

[0115] The determination of the lost electricity and the payer for the lost electricity in this invention includes:

[0116] The blockchain platform uses a pre-trained neural network model to predict the energy loss of the mobile power supply entity and the power consumption entity in different power consumption processes based on the power supply entity's power consumption information before the energy interaction is completed, the power supply entity's power consumption information after the energy interaction is completed, the power consumption entity's power consumption information before the energy interaction is completed, and the power consumption entity's power consumption information after the energy interaction is completed.

[0117] The blockchain platform will perform on-chain authentication of the energy losses of the mobile power supply entity and the power consumption entity during different power consumption processes;

[0120] Step S3 in this invention includes:

[0121] The blockchain platform records transactions on-chain based on confirmation information from the receiving terminal, completing the on-chain transaction. After publishing the electricity information and energy transmission data of this energy interaction, the blockchain platform generates power supply orders and purchase orders related to the energy interaction. These are then mutually confirmed by both the electricity user and the mobile power supplier, realizing the on-chain record-keeping function. This ledger is collectively maintained by all users on the chain and is tamper-proof. Simultaneously, the blockchain platform has open interfaces for information exchange and data sharing with power trading platforms, vehicle networking platforms, and government regulatory platforms, further ensuring the accuracy of charging information, the security of the interaction process, and that electricity transaction prices comply with electricity standards.

[0122] Example 2

[0123] To further describe the blockchain-based energy interaction method provided by this invention, this embodiment provides an example of energy interaction between an electric ride-hailing vehicle and a passenger's handheld device. This embodiment is only used to more clearly illustrate the technical solution of this invention and should not be used to limit the scope of protection of this invention. This embodiment is as follows... Figure 2 The illustration shows an example of energy interaction between an electric ride-hailing vehicle and a passenger's handheld device, which can solve the problem of passengers urgently needing to charge their devices during a ride but being unable to determine their value. In this mode, the energy is completely fragmented, and the process includes the following steps:

[0124] Step 1: After the electric ride-hailing vehicle has finished charging, the charging power and current power information are recorded on the blockchain. This information serves as the basis for consensus information, ensuring that the vehicle's power value has not been tampered with.

[0125] Step 2: Electric ride-hailing vehicles publish their available power supply capacity and select a power supply price range on the blockchain. At the same time, the blockchain will complete the status rating of the ride-hailing vehicles. This rating is related to the power supply price range. It should be noted that electric ride-hailing vehicles consume a lot of electricity during operation, and the available power supply capacity will be limited to a lower energy level during operation, mainly interacting with wearable and handheld devices. During shutdown, the power supply will mainly be selected from the power grid, public facilities and large electrical equipment.

[0126] Step 3: The current battery level of the passenger's handheld device is recorded on the blockchain, and the power demand of the handheld device is broadcast on the blockchain, and the electricity price range is selected.

[0127] Step 4: Passengers board electric ride-hailing vehicles. Given a confirmed vehicle, passengers manually select the electric vehicle for power supply. If the price matches, passengers choose the charging service, completing the interaction. It's important to note that electric ride-hailing vehicles exchange energy during operation. Energy loss during operation is determined by the current rating. Historical operating data models and neural prediction algorithms calculate power consumption during operation. When passengers select a power supply vehicle, they implicitly accept the power supplier's rating. The historical operating data model here obtains the relationship curve between battery degradation and time through statistical analysis of charging and discharging data from numerous similar electric vehicles.

[0128] Step 5: After charging is completed, the current battery level of the electric ride-hailing vehicle and the handheld device is recorded on the blockchain. The discharge battery level of the electric ride-hailing vehicle, the charging battery level of the handheld device, and the battery level lost during transmission are also recorded on the blockchain.

[0129] Step 6: Both parties confirm the interaction order, and the order is recorded on the blockchain.

[0130] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention. For example, blockchain-based methods for energy interaction between electric vehicles, energy interaction between electric vehicles and public facilities, and energy interaction between electric vehicles and the power grid should also be considered within the scope of protection of the present invention.

[0131] Example 3

[0132] This invention also provides a blockchain-based energy interaction system. This system utilizes blockchain technology to enable electric vehicles as mobile power sources to interact with other entities (wearable and handheld devices V2P, other electric vehicles V2V, public facilities and household appliances V2H, power grid V2G, etc.) via energy interaction (V2X mode). This invention includes: energy interaction scenarios and blockchain interaction methods, as well as an interaction system built to achieve energy interaction, including system design architecture, consensus mechanisms for charging and discharging energy, energy interaction processes, and on-chain information interaction, such as... Figure 3 As shown.

[0133] The blockchain-assisted V2X energy trading scenario mainly realizes various situations in which electric vehicles that can be powered can interact with other entities. The trading scenarios and methods include: (1) Electric vehicles powering personal wearable and handheld devices (V2P mode). Compared with electric vehicles, portable devices have lower power consumption and higher power consumption frequency, and fragmented power consumption is the most obvious. The transaction may occur in various locations such as electric taxis, electric ride-hailing vehicles, and electric buses. When the transaction interaction is required, the integration capability of the blockchain can be used to realize energy interaction directly, quickly and efficiently on the chain; (2) Electric vehicles discharging to other electric vehicles (V2V mode). When other electric vehicles suddenly lose power and break down, the cost of long-distance transportation is high and the time is long. If the energy between electric vehicles is used to achieve this, the energy interaction can be realized. Interaction, with the help of blockchain on-chain broadcasting and transaction matching, can more easily solve the urgent need for electricity; (3) Electric vehicles supply electricity to public facilities and household appliances (V2H mode). When the power supply facilities of public facilities, office areas and other locations suddenly lose power and need to be urgently dispatched by energy storage equipment, the power supply service can be provided by publishing the power demand on the chain and the electric vehicles on the chain responding; (4) Electric vehicles assist the power grid in energy interaction process (V2G mode). With the continuous deepening of the vehicle-to-grid interaction business model, the energy storage role of electric vehicles helps the power grid to realize the consumption of new energy and solve the problem of power overload. This is one of the important roles of large-scale electric vehicles assisting the power grid. With the help of the information integration capability of blockchain, the scale and commercial value of vehicle-to-grid interaction can be improved.

[0134] The system architecture of this interactive system is divided into three parts: the resource layer, the service layer, and the application layer. Figure 4 As shown

[0135] The resource layer includes various energy trading entities, including electric vehicles that supply power and diverse electricity users that exchange energy with them. It is used to store information about each energy trading entity and to connect with each energy trading entity to obtain and store energy trading-related data.

[0136] The service layer is implemented by a blockchain platform. This blockchain platform provides multiple transaction scenarios; it also initiates transaction requests based on the selected transaction scenario by calling the service layer, determines the electric vehicle providing the power supply service from the energy trading entities managed by the resource layer, and confirms the transaction under the selected transaction scenario. Figure 5As shown, the blockchain platform provided by this invention provides basic security capabilities. The blockchain platform includes an interface module and multiple functional modules. The interface module supports the access of mobile power supply entities such as electric vehicles and the access of energy-consuming entities. Each functional module realizes the energy interaction capability of electric vehicles. Each functional module does not require additional devices and completes data authentication by relying on big data models and neural network algorithm prediction algorithms. Functional module 1 is the charge / discharge metering submodule, which mainly completes the on-chain accounting of electric vehicle charging and discharging power. Functional module 2 is the energy loss metering submodule, which mainly completes the identification of energy loss values ​​of electric vehicles during placement, use, and transmission. Through historical data analysis and neural network algorithm prediction, it can assess the energy loss of each electric vehicle and each entity during placement, use, and transmission, and realize on-chain authentication. Placement and use losses belong to the electric vehicle owner, while transmission losses are paid by the energy recipient. Functional module 3 is the transaction handshake submodule, which helps users on the chain to achieve rapid interactive authentication. The transaction handshake submodule can be recommended on the chain or use a manual input selection mode to improve energy interaction efficiency. Functional module 4 is the order management submodule, which realizes on-chain accounting function based on terminal confirmation information and completes on-chain transactions. This ledger is collectively maintained by all users on the chain and cannot be tampered with. At the same time, the blockchain platform has open interfaces for information interaction and data sharing with power trading platforms, vehicle networking platforms, and government regulatory platforms, further ensuring the accuracy of vehicle charging information, the security of the interaction process, and that the electricity trading price complies with electricity standards.

[0137] The application layer includes user terminal apps involved in the energy interaction between electric vehicles and various entities. The terminal apps provide multiple transaction scenarios; help each entity complete the on-chain accounting of the current power consumption when an event occurs, complete the on-chain broadcast of electric vehicle energy supply and energy demand of each entity, and realize on-chain order confirmation when the energy interaction is completed. Specifically, it is used to initiate a transaction request by calling the service layer based on the selected transaction scenario, determine the electric vehicle providing power supply service from the energy trading entities managed by the resource layer, and realize transaction confirmation under the selected transaction scenario.

[0138] The charging and discharging energy consensus mechanism in this scheme primarily utilizes the consensus capabilities of blockchain to complete the electric vehicle status rating and energy loss assessment. Since electric vehicles of different types, with different power consumption processes and varying service lives, will have different battery charging and discharging capabilities and discharge damage, to ensure fair transactions, the battery's charging and discharging capabilities will be rated based on historical operating data models and neural prediction algorithms. The rating is from 1 to 10 (10 being the highest). Electric vehicles with stronger battery power supply capabilities and less battery damage will have higher ratings and will be prioritized for on-chain interactions. Energy is lost during use, placement, and transmission. The energy loss assessment mainly focuses on the value assessment of the energy transmission process, also with a rating from 1 to 10 (10 being the highest). This assessment primarily evaluates various power users; power recipients with less loss during transmission and more sufficient energy reception will have higher ratings and will also be prioritized for on-chain interactions.

[0139] To achieve on-chain data transmission, on-chain energy sharing, on-chain energy alerts, and on-chain energy control, this solution's energy interaction process and on-chain information exchange are as follows: Figure 6 As shown. After each entity completes charging, the charging amount and current power level are recorded on the blockchain. The power supply vehicle will broadcast its available power supply capacity and target users on the blockchain, and select a power supply price range. The price range is provided by the blockchain platform and is related to the electric vehicle's status evaluation. The higher the evaluation level, the higher the priority and the higher the electricity price. Users with electricity demand will broadcast their electricity demand on the blockchain and select an electricity price range. The price range is provided by the blockchain platform and is related to the energy loss assessment of the electricity user. The higher the evaluation level, the higher the priority and the lower the electricity price. The two parties to the transaction reach an interactive agreement through the blockchain's handshake module. After the transaction is completed, the discharge amount, lost amount, and charging amount are recorded on the blockchain as the data basis for on-chain evaluation. Finally, the two parties to the transaction confirm the power supply and purchase bills, and complete the on-chain accounting.

[0140] The technical solution of this invention relies on the integration capabilities of on-chain transactions to effectively fragment the energy of electric vehicles and improve the energy interaction capability; it incorporates energy usage loss calculation and transmission loss calculation into the blockchain consensus algorithm to realize a trusted transaction mechanism for energy interaction among various entities, ensuring fair transactions of electric vehicles charging and discharging with multiple entities; based on the unforgeability of blockchain, it guarantees the data security of the charging and discharging process and safeguards the vested interests of various entities.

[0141] The technical solution provided by this invention can refine the processing of interactive energy between electric vehicles and electricity users, enabling reliable energy information exchange. Through a blockchain consensus algorithm, energy losses before and after transactions are confirmed among the stakeholders, resolving disputes over energy storage and transmission, and preventing data tampering during storage and transmission. Leveraging the technical characteristics and advantages of blockchain, a V2X multi-stakeholder mutually trusted energy interaction system is established. This method can improve the supply capacity of electric vehicles as mobile energy storage devices, increase energy flow efficiency, and help improve the elasticity of electricity supply and demand and the operational efficiency of the power grid.
