Description

Technical Field

[0001] The present invention relates to the field of new energy consumption, and particularly to a method and system for determining the charging components of electric vehicles. Background Art

[0002] With the development of electric vehicle-related technologies and the strong promotion of new energy vehicles by the state, the sales volume of electric vehicles has been increasing year by year. However, the phenomenon of large-scale disorderly charging of electric vehicles is becoming more and more serious. On the one hand, disorderly charging refers to the uncertainty brought to the distribution network dispatching when electric vehicles charge during peak electricity consumption periods; on the other hand, it means that electric vehicles charge with electricity generated from non-renewable resources, indirectly causing environmental pollution. In addition, as renewable resources, wind and light resources have been widely used all over the world, but there have always been problems with the consumption of wind and light resources. To sum up, the current new energy power generation and large-scale disorderly charging of electric vehicles pose a severe challenge to the economic operation of the distribution network. If two clean energy sources, wind and light, are used to provide charging services for electric vehicles, not only can the consumption of new energy be increased, but also the virtuous interaction of the clean energy trading-production-distribution-consumption ecological platform can be promoted. Therefore, the consumption of new energy can be improved by guiding the orderly charging of electric vehicles. In order to guide the orderly charging of electric vehicles, suppliers encourage electric vehicle users to charge with green electricity through subsidy policies. Green electricity refers to electricity generated from new energy. To determine whether an electric vehicle has charged with green electricity, it is necessary to determine whether there is green electricity in the charging components of the electric vehicle. Due to the characteristics of blockchain such as immutability, traceability, and trustworthiness, it has been widely used in the electricity market.

[0044] To better understand the present invention, the content of the present invention will be further described below in conjunction with the accompanying drawings of the specification and examples.

[0045] Example 1: As Figure 1 shown, a method for determining the charging components of an electric vehicle provided in this embodiment includes:

[0046] S1 Obtain the charging order number of the electric vehicle;

[0047] S2 Parse the charging order number to obtain the identifier of the charging component corresponding to the electric vehicle during the charging behavior;

[0048] S3 Determine whether the charging component contains a type that meets the set requirements based on the identifier of the charging component;

[0049] Among them, the type includes green electricity and non-green electricity; the identifier is generated through a consortium blockchain.

[0050] The background of the technical solution provided in this embodiment is: the invention of electric vehicles has alleviated the panic caused by the depletion of automobile fuel, and also reduced automobile exhaust emissions. However, if the electricity charged by electric vehicles is generated by non-renewable resources, it indirectly pollutes the environment. At the same time, the phenomenon of wind and power abandonment needs to be solved urgently. If new energy vehicles are guided to use new energy electricity, the consumption of new energy electricity can be improved, especially in areas near new energy power plants. Local consumption can bring higher economic benefits. Provide rewards for new energy vehicles that use new energy electricity. To implement the rewards, it is necessary to determine whether the new energy vehicles are charged with new energy electricity.

[0051] Therefore, this embodiment provides a method of obtaining the charging order number of the electric vehicle and parsing the obtained charging order number, obtaining the identifier pre-added for the type of electricity being charged when the electric vehicle is charging through the parsing, and determining the type of electricity being charged by the electric vehicle through the identifier.

[0052] The solution provided in this embodiment can be used to guide electric vehicles to charge green electricity to improve the consumption of new energy electricity. To determine whether electric vehicles are charged with new energy electricity, that is, green electricity, it is necessary to add a unique identifier to the green electricity charged by the electric vehicle through the alliance chain, generate a charging order number based on the identifier, and then determine whether the electric vehicle is charged with green electricity by parsing the charging order number. This solution is not limited to identifying green electricity only, but can also identify non-green electricity according to actual needs, or identify specific types of green electricity such as wind power generation and photovoltaic power generation, and determine the components charged by the electric vehicle through the identifier, thereby reflecting the consumption of various types of electricity. The identification can be achieved through blockchain.

[0053] The embodiments of the present invention utilize the open, transparent, and tamper-proof technical characteristics of blockchain and operating mechanisms such as privacy protection and smart contracts to create an innovative "blockchain + new energy" model, realize a new energy vehicle charging and new energy electricity technology platform with mutual trust and resource sharing among multiple parties, promote the benign interaction of the clean energy trading-production-distribution-consumption ecological platform, enhance the mutual trust and resource sharing among multiple parties in the ecological system, break the interaction barriers between new energy producers and consumers, and enhance the efficiency of new energy utilization in the whole society.

[0054] Based on blockchain technology, a green electricity traceability system for new energy vehicles is provided. Through the application of blockchain technology, new energy vehicles can use new energy electricity, improve the friendly interaction capabilities of the smart car networking platform, and provide a technical basis for electric vehicle users to participate in the consumption of clean energy. Relying on the abundant electric vehicle electricity resources, the advantages of blockchain technology are used to open up the entire link of clean energy trading-production-distribution-consumption, and the power transaction information is opened up through blockchain technology. At the same time, it breaks the interaction barriers between new energy production and consumption, and enhances customer participation in charging. It lays a technical foundation for guiding user charging behavior in the future, strengthening the dispatching capabilities of the entire clean energy network, and promoting the production and consumption of clean energy.

[0055] The traceability mechanism for new energy vehicles to consume new energy electricity provided in this embodiment includes:

[0056] The distributed ledger, data privacy and security, data accuracy and rights-based mechanisms of blockchain break through the information barriers between the trading center, dispatching and electricity users, and promote data sharing and collaboration. The electricity components in the charging order are given unique digital identifiers, and the green electricity can be traced back by tracing the digital identifiers. Figure 2 As shown, through core technologies such as asymmetric encryption algorithms and consensus mechanisms, mutual trust and secure transmission of data among institutions are achieved; distributed storage, multi-point maintenance, and cross-chain collaborative technologies are used to improve the collaborative efficiency of various entities; and smart contracts are used to ensure the transparency of the business execution process and realize the trusted generation and transmission of credentials.

[0057] With the help of the technical characteristics and advantages of blockchain, a technical platform for "new energy vehicles with new energy electricity" with mutual trust and resource sharing among multiple parties is established. The information of power trading centers, dispatching centers, Internet of Vehicles platforms and social operators is integrated to trace the energy types and regions for charging new energy vehicles; the infrastructure for the formation of green electricity tokens for new energy vehicles with new energy electricity is established, and green electricity tokens and green electricity charging orders are introduced to strengthen the user's sense of participation in the use of green electricity according to the user's diverse charging preferences; a circulation mechanism for token archiving, auditing and distribution is established to improve the policy guidance foundation for new energy vehicles with new energy electricity. In order to meet the needs of new energy vehicles with new energy electricity and realize the service capability of electric vehicle electricity consumption for the overall power grid to reduce peaks and fill valleys, this project is planned to realize the green electricity traceability of "new energy vehicles with new energy electricity" based on blockchain technology, promote the benign interaction of the clean energy production-distribution-consumption ecological platform, and support peak reduction and valley filling, clean energy consumption and other businesses.

[0058] According to the various usage patterns of users, the type and origin of new energy are matched based on blockchain technology. When the user completes the charging behavior, a corresponding token number will be generated. One type of electricity in the charging order corresponds to a token, which records the source, type, and charging amount of electricity. Through the three dimensions of quantity, price, and time, the type and region of energy used by new energy vehicles are traced.

[0059] like Figure 3 As shown, the architecture design for new energy vehicles to absorb new energy electricity is based on the underlying blockchain technology platform, and builds a green electricity traceability application for new energy vehicles on the smart Internet of Vehicles platform. By opening up the power trading system, the traceability of charging orders is achieved based on the e-charging APP, providing a technical basis for electric vehicle users to participate in the absorption of clean energy, and improving users' charging experience and sense of participation. The traceability process is the process of determining the charging components.

[0060] Building the underlying blockchain platform, including constructing a consortium blockchain participated by charging operators, power trading centers, and dispatching centers through the underlying blockchain platform. According to the operation mechanism and business requirements of the consortium blockchain, customize and develop functions such as partition consensus, privacy protection, and smart contracts, and provide common services such as accessing the blockchain for the participants in the consortium blockchain.

[0061] This embodiment provides data uploading to the blockchain and smart contract development, including: designing the transmission service and interface standard of the blockchain, realizing the uploading of data such as power trading center, dispatching curve, and charging order to the blockchain, including relevant information such as green power contract, contract announcement number, sending end, receiving end, power type, and dispatching curve. At the same time, develop a smart contract program to generate green power tokens for the smart contract automatically triggered for each green power charging order, and realize the generation and circulation of "green power tokens", and provide token query services for the front-end business.

[0062] This embodiment provides the development of a green power traceability management system, including developing a green power traceability management system based on the intelligent vehicle networking platform, using the blockchain to obtain green power transaction information and dispatching curve information, developing a new energy characteristic curve algorithm, and realizing the order matching mechanism for the ordered green power submitted by each operator in the consortium blockchain, and providing maintenance services for the entire life cycle of green power tokens. The main functions include green power contract management, green power dispatching management, green power inventory management, green power order matching management, green power token management, etc. At the same time, provide services such as displaying green power tokens on the blockchain and verifying green power tokens on the blockchain for the APP. The order matching mechanism for the ordered green power submitted by each operator in the consortium blockchain of this embodiment includes based on the rules of the matching time and electricity quantity of green power in each province, and based on the inventory of green power at each time point, deducting from the inventory according to the first-come-first-served rule.

[0063] This embodiment also provides the development of the e-charging APP function, including: to increase the user's sense of participation and experience, provide functions such as online green power selection, token management, and charging report for charging users based on the e-charging APP 3.0. Develop a green power charging traceability module to provide green power configuration and usage preference settings. Through interacting with the underlying blockchain platform, green power traceability and other systems, realize the traceability of the user's charging order, and at the same time provide token query for the user through the blockchain interface, and regularly generate a green power charging report to enhance the user's sense of participation and honor.

[0064] This embodiment also provides the development of the order center function, including obtaining transaction information on the blockchain and setting priorities for green electricity types according to the green electricity traceability preferences of the operator. That is, when there is inventory for all types, the green electricity type with a higher priority is preferentially matched. The green electricity types include wind power, hydropower, photovoltaic power, etc. And according to relevant matching rules, a green electricity token is generated for the charging order provided to electric vehicle users to identify relevant information such as the green electricity type, green electricity source, charging operator, charging pile, etc. It is possible to combine with the green electricity traceability system to establish a message queue push mechanism to update to the green electricity traceability management system to complete the collaborative work between systems.

[0065] This embodiment also provides the visualization of blockchain information, including: developing a visualization display interface for new energy vehicle's use of new energy electricity to display relevant information such as green electricity transactions, green electricity consumption, and green electricity tokens in real time. At the same time, around the scenario of new energy vehicle's use of new energy electricity, relevant blockchain visualization information is provided, including global statistical information such as block height and green electricity tokens. At the same time, the immutable characteristic of the blockchain is used to provide a credible data endorsement for the displayed content.

[0066] This embodiment analyzes the results with the example of new energy vehicles consuming new energy electricity, including analyzing according to the data of the vehicle networking platform. The peak periods of charging demand mainly concentrate around the evening rush hour and before going to bed at night. The charging behavior mainly occurs in three intervals: the morning rush hour, the evening rush hour, and around 23:00 at night. And the charging volume from 1:00 to 7:00 is the least, and the charging power from 8:00 to 14:00 is significantly less than that from 15:00 to 0:00. It can be seen that the behavior guidance of new energy vehicles using new energy electricity requires the support of specific data and policies.

[0067] In 2019, the pilots of new energy vehicles using new energy electricity were launched and implemented in Beijing, Zhejiang, and Chongqing. Beijing: 0.75 billion kWh was completed in 2019; the types of electricity purchased were: green electricity transactions for poverty alleviation in Qinghai and wind power in Gansu. Zhejiang: 0.93 billion kWh was completed in 2019; 0.465 billion kWh of green electricity was additionally purchased from the northwest in July; 0.48 billion kWh of green electricity was additionally purchased from Sichuan in August. Chongqing: 0.6 billion kWh was completed in 2019, purchasing hydropower from Sichuan.

[0068] The green electricity traceability of the State Grid pile orders in the Beijing area in 2019 was carried out using the new energy vehicle's use of new energy electricity system based on blockchain technology. A total of approximately 0.4 billion kWh of green electricity was traced, and 1.7 million green electricity tokens were generated. It positively proves that electric vehicles can consume new energy electricity and is beneficial to giving play to the energy-saving and environmental protection benefits of electric vehicles. The carbon dioxide emission reduction amount and the saved energy equivalent per 1 kWh of electric energy consumed by electric vehicles will be increased by 4.2 times and 1.8 times respectively compared with the current situation.

[0069] Through the above data, it can be verified that guiding new energy vehicles to use new energy electricity through the technical solution provided in this embodiment can not only improve the consumption of new energy electricity, but also reduce the carbon dioxide emissions.
