➤The energy interaction between new energy vehicles and the power grid represents the development and layout of distributed energy. It is of great significance in power dispatching and responding to major natural disasters in some remote areas. This is a major breakthrough for it to help new infrastructure.
The General Office of the State Council recently issued the "New Energy Automobile Industry Development Plan (2021-2035)" (hereinafter referred to as the plan). The author believes that the strategic significance of combing the full text of the plan is far beyond the development of new energy vehicle products and the technical route itself. The strategic intention of using intelligent new energy vehicles to help new infrastructure, overtaking on the corners of the intelligent new energy vehicle track, and accelerating the entry into automobiles The strategic goals of a powerful country are very clear.
The plan proposes that by 2025, the average power consumption of new pure electric passenger vehicles will be reduced to 12.0 kWh/100 kilometers, the sales of new energy vehicles will reach about 20% of the total sales of new vehicles, and highly autonomous vehicles will achieve restricted areas and Commercial application in specific scenarios.
Since 2010, China's new energy vehicles have grown rapidly, with sales accounting for 55% of global new energy vehicles. At present, China has the largest number of new energy vehicles in the world.
This data will firmly consolidate my country's leading position in the number of new energy vehicles. The average power consumption of new pure electric passenger cars has dropped to 12.0 kWh/100 kilometers. The big game behind it is to guide product energy consumption more scientifically, effectively reducing my country's dependence on foreign oil, and promoting energy conservation and emission reduction. Highly autonomous vehicles realize commercial applications in restricted areas and specific scenarios, which outlines the pulling effect of smart new energy vehicles on the 5G and Internet of Vehicles industries.
The plan proposes to use pure electric vehicles, plug-in hybrid (including extended range) vehicles, and fuel cell vehicles as the "three verticals" to lay out the entire vehicle technology innovation chain. Take the power battery and management system, drive motor and power electronics, network connection and intelligent technology as the "three horizontal" to build a key component technology supply system.
Through comparison, it can be found that the "three verticals" remain unchanged, and the "three horizontals" have evolved from the past multi-energy powertrain system, motor drive system and control unit, power battery and battery pack management system to networked and intelligent technology. , Ranks in the "three horizontal", which means that network connection and intelligence will become the focus of research.
Coincidentally, "Intelligent Connected Vehicle Technology Roadmap 2.0" was announced recently. Compared with version 1.0 in 2016, version 2.0 proposes that half of new cars will have L2/L3 autonomous driving in five years. In 2030, the proportion of L2 and L3 autonomous driving models will reach 70%. By 2035, China will plan for intelligent networked vehicles. The technology and industrial system has been fully established, the industrial ecology is sound and perfect, the level of intelligence of the entire vehicle has been significantly improved, and the large-scale application of network-connected highly autonomous intelligent connected vehicles. This corresponds to the planning goal and fully demonstrates the powerful new infrastructure driving force of the Internet of Vehicles and smart new energy vehicles.
The plan is clear to strengthen the energy interaction between new energy vehicles and the power grid (V2G). In this regard, officials from the Ministry of Industry and Information Technology recently stated that they will accelerate the construction of standard systems such as V2G interfaces and vehicle-network interaction, and encourage places where conditions permit to explore and develop new energy vehicles and power grid (V2G) energy interaction application demonstrations, and take advantage of the distributed advantages of new energy vehicles.
V2G refers to the two-way flow between electric vehicles and the power grid. A large number of electric vehicles can act as a buffer between the power grid and renewable energy, and play the role of a dynamic balance of electricity. During low-cost electricity and non-peak hours, electric vehicles use the grid to charge, and during peak electricity consumption, electric vehicles can sell electricity back to the grid. In other words, in the future, new energy vehicles will still be smart mobile terminals for information interaction and smart energy storage units. The energy interaction between new energy vehicles and the power grid represents the development and layout of distributed energy. It is of great significance in power dispatching and responding to major natural disasters in some remote areas. This is another breakthrough point for it to help new infrastructure.
The plan points out that the new energy vehicle industry ecology is gradually evolving from the "chain relationship" between parts, vehicle R&D, production, and marketing service companies to a "network" involving multiple actors in various fields, such as automobiles, energy, transportation, and information communications. State ecology". Cross-industry, cross-field integration and innovation and more open and inclusive international cooperation have become the characteristics of the times in the development of the new energy automobile industry.
The author believes that this is a new infrastructure bonus for China's unswerving promotion of its new energy vehicle strategy and a higher-dimensional curve overtaking path to build a powerful automobile country.
