In 2021, China's new energy automobile industry developed rapidly, with sales of 3.521 million units, ranking first in the world for seven consecutive years, with a market share of 13.4%. Whether the service guarantee capacity of electric vehicle charging infrastructure can meet the demand has aroused widespread concern.
The National Development and Reform Commission, the National Energy Administration and other ten departments recently issued the "Implementation Opinions on Further Improving the Service Guarantee Capacity of Electric Vehicle Charging Infrastructure", which clarifies that by the end of the "14th Five-Year Plan", the charging guarantee capacity of electric vehicles in the mainland will be further improved, forming a moderately advanced, balanced layout, intelligent and efficient charging infrastructure system, which can meet the charging needs of more than 20 million electric vehicles.
How to improve the service guarantee capacity of electric vehicle charging infrastructure
Charging piles in the community will increase significantly. The "Implementation Opinions" proposes that the mechanism for promoting the construction of charging facilities in residential communities should be improved. Promote the construction of charging facilities in existing residential communities, and residential communities with installation conditions should be equipped with a certain proportion of public charging parking spaces, and establish a time-sharing mechanism for charging parking spaces to create conditions for users to charge. Strictly implement the requirements for the allocation of new residential communities. Newly built residential communities should ensure that 100% of the fixed parking spaces are built with charging facilities or reserved installation conditions. Innovate the business model of charging services in residential communities, and encourage new models such as "sharing near parking spaces" and "multi-vehicle and one pile".
The ability to guarantee charging and replacing electricity in urban and rural areas will be improved. Strengthen the layout of charging networks in counties and townships. Accelerate the effective coverage of the expressway fast charging network, accelerate the formulation of phased coverage plans for the expressway fast charging network in various provinces, clarify the standards and specifications for the construction of expressway fast charging stations, and include fast charging stations in the scope of supporting infrastructure in the expressway service area. Strive to 2025, the national ecological civilization pilot zone, air pollution prevention and control key areas of the highway service area fast charging station coverage rate of not less than 80%, other areas not less than 60%.
Technological innovation powers charging. The "Implementation Opinions" proposes to promote the interactive technological innovation and pilot demonstration of the vehicle network, and support the upstream and downstream of the industrial chain such as power grid enterprises and car companies to build an integrated innovation platform for new energy vehicles and smart energy. Actively promote pilot demonstrations, explore the implementation path for new energy vehicles to participate in the electricity spot market, and study and improve the trading and dispatch mechanisms for the consumption of new energy vehicles and the storage and discharge of green electricity. Explore the integrated pilot application of "light storage, charging and discharging" in units and internal charging facilities in the park. Encourage the promotion of intelligent and orderly charging, gradually increase the proportion of intelligent and orderly charging pile construction, encourage intelligent and orderly charging into the functional scope of charging piles and new energy vehicle products, and accelerate the formation of unified industry standards. Strengthen the innovation and standard support of charging and replacing technology. Accelerate the promotion and application of the power exchange mode. Focusing on scenarios such as mine farms, ports, and urban transfers, we will support the construction and layout of special substations, accelerate the exploration and promotion of vehicle-electricity separation modes, and promote the electrification transformation of heavy trucks and internal port collection cards.
In addition, local governments will be encouraged to strengthen subsidies for demonstration facilities such as high-power charging and vehicle network interaction to promote the transformation and upgrading of the industry. Innovative use of financial instruments such as special bonds and funds, focusing on supporting charging facilities and supporting power grid construction and transformation projects. Encourage all kinds of financial institutions to provide financial support for the construction of charging facilities through various channels. Encourage insurance institutions to develop insurance products suitable for charging facilities.
Zhang Jianping, deputy director of the Academic Committee of the Research Institute of the Ministry of Commerce, told reporters that the current construction speed and spatial layout of electric vehicle charging piles cannot meet the practical needs of the rapid growth of new energy vehicle sales. To improve the service guarantee capacity of electric vehicle charging infrastructure, it is necessary to do a good job in medium- and long-term planning to ensure the construction speed and spatial layout of charging infrastructure. The "Implementation Opinions" put forward specific construction opinions from multiple angles, which is conducive to improving the service guarantee capacity of electric vehicle charging infrastructure and meeting the growing demand for electric vehicle charging.
According to the requirements of the document, the new residential community should ensure that 100% of the fixed parking spaces are built to build charging facilities or reserve installation conditions, which on the one hand reflects the determination of the state to develop new energy, on the other hand, for real estate development enterprises, it is necessary to have more thinking about the design, construction and cost of charging piles; On the other hand, it means that the cost of real estate development will increase again.
The following focuses on the cost and construction mode of charging piles.
Real estate project charging pile construction mode
According to the policy requirements, the new community needs to build charging piles, which are mainly divided into three construction modes:
Mode 1: 100% construction of charging facilities for fixed parking spaces
Mode 2: A certain proportion of fixed parking spaces to build charging equipment, a certain proportion of reserved installation conditions, but construction + reservation ratio = 100%
Mode 3: 100% reserved installation conditions for fixed parking spaces
Cost analysis of charging piles for real estate projects
1. The main cost composition of the charging pile
The construction of charging piles involves many contents, such as chargers, transformers, cables, distribution cabinets, battery maintenance equipment, monitoring equipment, switch cabinets, etc., and the proportion of each cost is shown in the following figure.
2. Charging pile cost analysis
In addition to the construction of the charging pile itself, many accessories and facilities are common to the pile, such as distribution rooms, cables, bridges, etc., so the construction cost of each pile will vary, and the ratio of parking spaces, equipment material brands, etc., the cost of a single pile is about 2000 yuan / ~ 6000 yuan / range.
3. Other cost increases caused by charging piles
Setting up a charging pile is not only about building the charging pile itself, but also about the increase in other costs due to the charging pile.
3.1 Increase in underground area
Although there are various forms of charging piles to choose from (column type, wall mounted type, car gear type, etc.), it is inevitable to increase the area in order to use the feeling and equipment.
usually:
The area of single parking spaces without reserving charging pile installation space increases by about 1.9 square meters, and if the charging pile installation space is reserved, the single parking area increases by about 3.05 square meters.
3.2 Increased capacity of electricity
Whether it is reserved installation conditions or one-time installation, the setting of the charging pile will increase the project capacitance demand, so the increase due to power capacity must be considered when doing design and cost control.
A small project, perhaps an 800kVA box transformer can meet the demand; However, if you set up 20 charging parking spaces and configure 10 120kW dual-gun fast charging piles, you need 1200kVA capacity.
3.3 Increases in other costs
Let's take two fire zones as an example
Increase the cost of construction: increase the fireproof partition wall, fireproof roller blinds, fire doors, fan rooms, etc., and increase about 40 yuan / square meter per square meter
Structure increase cost: increase 4 water collection pits, about 10,000 yuan / one
HVAC increases costs: 4 smoke exhaust fans, the comprehensive price of 19,000 yuan / piece
Electrical appliances increase costs: charging bridge is about 800 meters, about 80 yuan per meter
Water supply and drainage increase costs: 8 fire hydrants, 8 drainage pumps
The above increase cost is about 70 yuan / square meter (here the loss of revenue caused by the decrease in parking spaces caused by the increase in parking space area is ignored).
brief summary
The country to promote the new energy strategy, electric vehicles are one of the key links, it is expected that in the next 5 to 7 years, electric vehicles will fully replace the current gasoline vehicles, but although the status of new energy vehicles in the entire energy strategy is so important, but from the current number of new energy vehicles far from being comparable to traditional gasoline vehicles, the reason is that it is very important that the new energy vehicle mileage anxiety problem.
With the substantial growth of demand for new energy vehicles, the imbalance between supply and demand of charging piles and the mismatch of time and space are being magnified in front of the market. Therefore, the latest document of the National Development and Reform Commission fully explains the requirements of the state for the new energy strategy.
For real estate enterprises, the promotion of new energy needs to build supporting facilities, which will inevitably further increase the construction cost of houses.
Only when we study the charging pile thoroughly and optimize it in place can we not only meet the national strategy, but also improve our own product competitiveness and corporate profitability.
