Deploy six priority tasks

(1) Coordinate the promotion of core technology research on vehicle-network interaction

Increase the key technology research of power batteries, increase the cycle life of power batteries to 3,000 times or more on the basis of no obvious increase in costs, and overcome battery safety prevention and control technologies under high-frequency bidirectional charging and discharging conditions. We have developed highly reliable, flexible, and low-energy vehicle-network interactive system architecture and bidirectional charging and discharging equipment, developed key technologies for grid-friendly charging and swapping stations such as optical storage and charging integration, and flexible mutual assistance of DC bus, and conquered the technology of accurate prediction and aggregation and regulation of massive distributed vehicle-network interactive resources. Strengthen the research on key technologies of vehicle-network interactive information interaction and information security, build a "vehicle-pile-network" full-chain intelligent and efficient interaction and collaborative security prevention and control technology system, realize "plug and charge" intelligent and convenient interaction, and ensure information security and power grid operation security.

(2) Accelerate the establishment of a standard system for vehicle-network interaction

Accelerate the formulation and revision of national and industry standards related to vehicle-network interaction, and give priority to the formulation and revision of key technical standards such as interactive interfaces, communication protocols, power regulation, scheduled charging, and vehicle wake-up in orderly charging scenarios, and strive to complete the formulation and revision of key technical standards such as charging and discharging equipment and vehicle technical specifications, vehicle pile communication, grid-connected operation, two-way metering, charging and discharging safety protection, and information security in bidirectional charging and discharging scenarios by the end of 2025. At the same time, we will improve the standard supporting testing and certification system, and promote the implementation of intelligent and orderly charging standard requirements in vehicle production access, charging pile production, installation, acceptance and other links. Actively participate in the cooperation of international standards in the field of vehicle-network interaction, and enhance the international influence of Chinese standards.

(3) Optimize and improve supporting electricity prices and market mechanisms

Encourage the development of independent peak-to-valley time-of-use electricity price policies for charging facilities with strong load guidance such as residents' personal piles, and establish a differentiated price system around residents' charging loads and residents' living loads, and strive to realize the full application of residents' charging peak-valley time-of-use electricity prices by the end of 2025, and further stimulate the flexible adjustment potential of various charging and swapping facilities. Research and explore the price mechanism of new energy vehicles and charging and swapping stations for grid discharge. Establish and improve the demand-side management and market trading mechanism for the aggregation of vehicle-network interactive resources, optimize and improve the auxiliary service mechanism, enrich the trading varieties, expand the scope of participation, increase the frequency and scale of vehicle-network interactive resources to participate in demand response, and explore the implementation path of various charging and swapping facilities as flexible resource aggregation to participate in the spot market, green certificate trading, and carbon trading. Encourage bidirectional charging and discharging facilities, storage/charging/optical storage and charging integrated stations, and battery swap stations to participate in the pilot demonstration of the power market through resource aggregation, and verify the equivalent energy storage potential of bidirectional charging and discharging resources.

(4) Explore and carry out comprehensive demonstration of two-way charging and discharging

Actively explore the bidirectional charging and discharging application mode of efficient integration of new energy vehicles with parks, buildings, family residences and other scenarios. Priority should be given to building a number of two-way charging and discharging demonstration projects for vehicles in the public sector such as official business, leasing, shuttle buses, school buses, sanitation, and public transportation; Combined with the pilot demonstration, actively explore the sustainable business model of two-way charging and discharging, improve the business process and management mechanism of two-way charging and discharging in typical application scenarios, establish and improve the battery quality assurance system of bidirectional charging and discharging vehicles, strengthen the protection of consumer rights and interests, strengthen the evaluation and summary of pilot effectiveness, and form a number of typical models and experiences that can be replicated and promoted.

(5) Actively improve the interactive level of charging and swapping facilities

Vigorously promote intelligent and orderly charging facilities, in principle, new charging piles uniformly adopt intelligent and orderly charging piles, and promote the intelligent transformation of existing charging piles as needed. Establish and improve the management system and process of intelligent and orderly charging in residential communities, clarify the responsibilities and rights of power grid enterprises, third-party platform enterprises and new energy vehicle users, and clarify the conditions and response requirements for orderly charging in communities. Encourage power grid enterprises to cooperate with charging operators to establish an efficient interaction mechanism between the power grid and charging and swapping stations, and improve the power response and regulation capacity of charging and swapping stations. Explore and study the verification methods and related standards and specifications for the power access capacity of different types of intelligent and orderly charging and swapping facilities, so as to effectively improve the access capacity of the distribution network. Charging operators are encouraged to accept the entrustment of owners to carry out "unified construction and service" of charging facilities in residential areas. Charging operators are encouraged to build integrated stations for optical storage and charging according to local conditions to promote the integrated development of transportation and energy.

(6) Systematically strengthen the support and guarantee capabilities of power grid enterprises

Incorporate vehicle-network interaction into power demand-side management and promote the construction of the electricity market as a whole. Support power grid enterprises to carry out vehicle-network interactive management in combination with the new power load management system, give priority to the unified access and management of charging and swapping facility resources of 10 thousand volts and above, and gradually cover all kinds of charging and swapping facility resources behind low-voltage distribution networks and gateway meters. Further improve the functions of the power grid demand-side management and power regulation and control platform, and provide basic support and technical services for vehicle-network interactive aggregation transactions. Accelerate the improvement of the requirements and technical specifications for grid connection, metering, protection control and information interaction of vehicle-network interaction, and explore the independent metering scheme of charging and swapping facilities behind the gate meter. Optimize the grid clearing and settlement mechanism, and support vehicle-network interactive load aggregators to directly participate in the clearing and settlement of the electricity market. ：
