The forum was chaired by Liu Jingwen from the Travel Service Department of the Ministry of Transport. 
Improve the network of charging facilities
Build transportation that satisfies the people
Liu Jingwen pointed out that in recent years, with the vigorous development of China's new energy vehicle industry, the demand for energy supplement for road travel by new energy vehicle owners has also been increasing. Scientific planning, overall classification to promote the construction and transformation of charging infrastructure along the highway, and accelerate the formation of a charging infrastructure network along the highway with full coverage of important nodes and good operation and maintenance services, is an important carrier to accelerate the construction of a strong transportation country and promote the development of the highway transportation network and energy network, and it is an important measure to serve the public highway travel and build people's satisfactory transportation. The construction of charging infrastructure network has always been a key factor related to the development of the new energy vehicle industry. According to Zou Peng, after long-term development, China has gradually established an ecology based on family slow charging in different scenarios, supplemented by public fast charging, and the construction of charging facilities along the highway is gradually improving, and the problem of charging difficulty is gradually being solved. However, at the same time, with the rising penetration rate of new energy vehicles, problems such as charging difficulties will continue to exist, and the development of China's charging and swapping infrastructure industry still has a long way to go. The "14th Five-Year Plan" is a critical period for the development of intelligent networked vehicles and new energy vehicles in China, which requires the industry to work together and move forward hand in hand, jointly create a new situation in industrial development, and make greater contributions to the construction of a manufacturing power, a network power, a transportation power, and an automobile power. It is the direction of the industry's joint efforts to continuously improve the highway travel experience of new energy vehicle owners, further improve the charging and swapping infrastructure system along the highway, and promote the high-quality development of the new energy vehicle industry. According to Xiao Yao, at present, China's charging and battery swapping facilities along highways are still facing many problems, such as insufficient total, uneven utilization, and insufficient security. Accelerating the construction of charging infrastructure along highways is not only to meet the needs of the public and build transportation that satisfies the people, but also to expand effective investment, promote the green and low-carbon development of the transportation industry, and serve the development of the national industrial strategy. Xiao Yao further pointed out that under the current economic situation, accelerating the construction of charging infrastructure along the highway will effectively solve the problem of electric vehicle charging and the worries of development, resolve the anxiety of electric vehicle owners for long-distance travel, boost the public's confidence in purchasing new energy vehicles, and further promote the consumption of new energy vehicles. In the next step, the Ministry of Transport will continue to promote the construction of charging infrastructure, and will accelerate the construction of charging infrastructure along highways in the "2024 transportation closer to people's livelihood", and continue to increase the number of charging piles and charging parking spaces in highway service areas. At the same time, the Ministry of Transport will further strengthen the guarantee of charging services, optimize and improve the charging pile to check the information, make good use of financial support policies, strengthen the construction of supporting power grids, and implement land use policies. In addition, the Ministry of Transport will also strengthen the coordination and cooperation of multiple departments, promote the socialization of charging infrastructure, guide all kinds of social capital to actively participate in the construction, form a unified and open, competitive and orderly charging service market, encourage charging operators and vehicle enterprises, Internet enterprises to actively explore business cooperation models, and fully create a good atmosphere for industry guidance, local support, and social participation in the construction of charging infrastructure. The integration of four networks solves the problem of development
Chen Guanjie said that under the dual carbon goal, the development of the new energy industry is both an opportunity and a challenge for the development of expressways. In this new track, it is the goal of every high-speed new energy company and the mission of every company's new energy people to build a highway charging and swapping network with high quality, good service and good efficiency, which can better promote the green development of transportation. In order to promote the high-quality development of the charging ecology and solve the development problem, Li Jian put forward eight suggestions from the two levels of external objective and independent decision-making. First of all, the external objective level, the first is to coordinate power grid enterprises to support the planning of highway power grid corridors, increase business expansion, and ensure high-power powerThe second is to coordinate with power grid enterprises to continue to implement the exemption of business expansion supporting load assessment requirements and the exemption of basic electricity charges for large industrial electricityThe third is to appropriately increase construction subsidies and increase operating subsidies to alleviate the operating pressure of expressway investorsThe fourth is to coordinate with the land department to give policy support to the supplementary requisition of land for the expansion of charging facilities. At the level of independent decision-making, the first is to comply with the trend that super fast charging will become the mainstream development direction of passenger cars, adhere to the moderate advancement, build the road of supercharging, and create three supercharging roads from Guangzhou to Zhanjiang, Guangzhou to Shaoguan, and Guangzhou to ShantouThe second is to adhere to low-carbon leadership, comprehensively promote the construction of distributed photovoltaic in service areas, and build energy storage systems in stagesThe third is to adhere to innovation-driven, pilot the "handshake" project through technical means, and reduce power loss. Fourth, we will work together for a win-win situation, build brand charging and swapping stations with new energy vehicle companies, and build a charging ecosystem at the exit of toll stations. "The transportation is fully electrified, and the integration of the four networks (referring to the Internet + radio and television network + telecommunication network + power grid) must be realized. Li Biao said that unified brand, unified platform, unified planning, unified standards, zoning operation and maintenance is the future development direction, power grid enterprises should not only provide products to meet the needs of users, but also build a platform, through value-added product and service innovation to guide users, to provide professional and diversified services, so as to achieve "liberation of users". At the same time, Li Biao also reminded that state-owned central enterprises must pay attention to controllable risks, compliant procedures, and guaranteed profits when promoting transportation networks and energy networks, which are in line with their main business. "Sinopec should not only operate oil products, but also develop in the direction of high-quality charging and battery swapping business, build a full-scene service brand, and build a 'multi-in-one' ecology of oil, gas, hydrogen and electric volt. For how to create a high-quality charging and swapping ecology, Wang Weimin put forward the following views: first, the large-scale construction of charging piles needs to follow three principles, one is the overall planning, from the overall design of the group company to build a national charging network;Second, it is necessary to unify the design, construction, platform, and operation and maintenance to form a network togetherThe third is classified implementation, which is uniformly implemented according to different scenarios. In addition, Wang Weimin also stressed that in the process of building charging piles and hydrogen refueling stations, safety must be put in the first place, and security, technical defense and civil air defense measures must be strengthened. Gao Jie said that high speed is the most anxious place for users, which is also the direction of Li Auto's next step. To achieve this goal, Gao Jie proposed a three-step strategy: the first step is to open up the intercity connectivity of the four economic belts, including the Beijing-Tianjin-Hebei region, the Yangtze River Delta, the Greater Bay Area, and Chengdu-Chongqing. The second step is to build a nine-vertical and nine-horizontal supercharging network on expressways in 2024, covering 70% of the country's high-speed main lines. The third step is to open up more than fourth-tier cities by 2025, covering more than 90% of the main lines of national expressways, which requires joint development with expressway companies and other partners. Intelligent management,
Open up new ideas for road network operation and maintenance
At the forum, Li Biao pointed out that "someone builds, someone manages, and can be sustained" is the nine-word policy of charging infrastructure investment, construction and operation services. Coincidentally, Wang Xiaobo also emphasized that in order to build a high-quality energy charging network, its operation and maintenance management is very important. Wang Xiaobo pointed out that the operation of third-party platforms can no longer meet the needs of highway operation at this stage, and highway operators need to establish their own charging station operation and management platform to meet the increasing user needs. Secondly, the fault recovery and handling of the charging pile should also have the ability to respond at the hour-level level, and in principle, the fault problem should be solved within one hour. In this regard, Wang Linxian also expressed a similar view. In his view, the high-speed charging equipment in the service area should have the characteristics of intelligent management in operation. For the operation platform, the functions of remote upgrade and remote control of equipment start and stop should be realized. The O&M applet needs to monitor the status of the charging pile in the service area in real time, and once an abnormality is found, the O&M personnel should be immediately notified through WeChat or SMS to ensure that the equipment is repaired in time. In addition, the use of big data and cloud computing technology for charging early warning and vehicle guidance is of great significance to meet the demand for large-scale travel charging. According to Jin Wenbiao, the biggest problem in the operation of Zhejiang Expressway service area is the shortage of capacity, and in order to alleviate the shortage of capacity, Zhejiang Expressway has made many efforts. The first is to expand the service area with large traffic and tight parking to create strong conditions for the expansion of charging pilesThe second is to implement the transformation and upgrading of the service area. In the past two years, Zhejiang has been improving relevant service facilities and adding charging piles through the adjustment of parking spaces. In addition, when designing and constructing the service area, Zhejiang Expressway will also include the equipment of charging piles as a rigid requirement in the relevant design content, saving subsequent reconstruction costs. How to improve the comprehensive service capacity of the service area?Jin Wenbiao put forward a number of suggestions: one is the conservation of land, the second is the low-carbon development, the third is the wisdom of management, and the fourth is the quality of service. At the same time, in terms of charging services, it is necessary to carry out intelligent services, provide more convenient and convenient travel service information, and implement a network operation. In terms of management services, Jin Wenbiao also encouraged the expressway companies to strengthen capital investment to promote and guide social funds to participate in the construction of charging stations. In Chen Guanjie's view, the establishment of a joint venture is a channel to achieve a win-win situation. First of all, the establishment of a joint venture company can realize resource sharing, and it is more convenient to use both software and hardware to improve the efficiency of energy replenishment and the fine level of operation and maintenance of charging stations in the service area. Secondly, the establishment of a joint venture company can achieve mutual promotion, and the vicious competition caused by the implementation of different entities can be effectively avoided through the unified operation of charging stations in the service area. In addition, it is possible to further share and analyze the traffic volume and charging volume to better develop and operate charging stations and achieve the effect of precise policy.
