With the increase in the number of electric vehicles, the number of charging piles is also increasing. Statistics from the National Energy Administration show that by the end of June 2024, the total number of charging piles in the country reached 10.244 million units, an increase of 54% year-on-year. Among them, 3,122,000 public piles and 7,122,000 private piles, with the total rated power of public piles exceeding 110 million kilowatts. Industry insiders pointed out that with the continuous growth of new energy vehicle sales and the large-scale development of autonomous driving, traditional charging piles have been far from meeting market demand, and it has become imperative to move from "pile" to "network".
Ⅰ What is a charging network?
The charging network is a deeply integrated intelligent charging system, emphasizing the interconnection of energy and data. It is classified according to urban and rural functional planning. For example, in a city, we must first make classification planning according to different charging scenarios, different vehicle needs, and different operating equipment requirements.
For example, the bus charging network is mainly used along the bus line and to meet the needs of daily bus travel, to meet the requirements of high power and field, including the high-power automatic flexible charging products used in the core cities, Shanghai and Chengdu, to meet the bus system. Logistics charging network, including ports, airports, docks, logistics transfer stations, heavy truck application scenarios, the need for exclusive logistics charging network, high power demand and rapid energy requirements are very clear and prominent.
In addition, as a passenger vehicle, especially including taxi, online car and private car daily travel, public travel is the most seen by all partners, but also a relatively large part of the investment, for private vehicles, 24 hours a day, more or in the family and enterprise park. Charging networks for the community and microgrids for enterprise parks are also an inevitable trend in the development of the industry.
Ⅱ How the charging network works
The charging network is a new type of infrastructure that links users, cars, batteries and energy. With the development of the automotive revolution, the attributes of the car have been transformed from a typical mechanical product to an electronic Internet product based on mechanical products, which will become the second mobile intelligent "device" after the mobile phone and enter thousands of households.
The charging network is an organic system composed of power transformation and distribution equipment, power electronic energy conversion and distribution equipment, intelligent scheduling system, big data and cloud platform, which supports the safe and efficient interaction between large-scale people, machines and things, and realizes the deep interaction of information, energy and data. It is the basic support for the development of large-scale electric vehicles, and a new form of two-way integration of new energy and new transportation.
Ⅲ What does the charging network include?
The construction of a charging network is not a matter of opening a bunch of charging stations and erecting a bunch of charging piles. Charging piles and charging stations are the foundation, but the most important thing is to form a network.
For example, Tesla, as a representative of its own charging network, currently has 1,870 superchargers and 16,585 superchargers around the world. In addition to the charging speed, the charging operation, the accuracy of information, payment, the follow-up of relevant software, the operation of charging stations, etc., all form a mature closed loop in the control of details. It solves not only the single event of charging, but also considers the user's use scenario and use experience, and regards charging as a system.
It is worth noting that this is precisely the basis of the charging network. It also requires technical support from multiple aspects. In addition to car companies, many technology and Internet companies will also participate, such as the HiCharger DC fast charge module released by Huawei not long ago.
As part of the "new infrastructure", the charging network is the hub between people, vehicles and energy, and maintains real-time online and a large number of interactions, with the application of 5G, vehicle networking and other technologies, the energy and data attributes of the charging network will be further played.
Ⅳ What is the difference between charging pile and charging network?
As different stages in the development process of the charging industry, charging piles and charging networks are two distinct products. If the charging pile is compared to the 1.0 stage of development, then the charging network is the 2.0 or even 3.0 stage of development.
Industry insiders pointed out that the biggest difference between the charging network and the charging pile comes from the fact that the charging network is equivalent to a physical network connection for each charging terminal and each charging station, so that each new energy vehicle can give priority to the new energy, photovoltaic, hydropower and electricity issued on the spot, so that new energy vehicles can be charged with new energy electricity and do not grab the load of the daily big grid. Especially in cities with electricity shortages, relying on the development of microgrids, local consumption of new energy can be achieved.
If the new energy power generation is too sufficient, such as in the noon period, when the solar power generation is very sufficient, new energy vehicles can become a flexible energy storage device that actively consumes new energy charging or power generation, and play a key positive role in the interaction of the vehicle network. When the load of the large power grid is insufficient, through the way of peak regulation and frequency regulation, the reverse power supply for the large power grid.
Ⅴ The value of urban charging network layout
① the advance layout of the charging network can provide more convenient charging services for new energy owners, solve the range anxiety, and improve the experience of owners. For cities where the development of new energy vehicles is relatively slow, the charging network can solve the charging problem of car owners and accelerate the promotion of local new energy vehicles by appropriately advancing the layout of the charging network.
② Improve the utilization rate of parking lot resources. Public charging stations are generally built in commercial complexes and attached parking lots of public buildings. In the current situation of urban parking resources shortage, parking and charging are combined into one, and the single parking function is expanded to both parking and charging functions, which can optimize the allocation of parking resources and effectively improve the utilization rate of urban land.
③ optimize the urban distribution network, ensure orderly charging when the scale development of new energy vehicles. If the characteristics of the power grid are ignored, large-scale construction of high-power charging equipment will cause disorderly charging, which will cause damage to the balance of the power grid. Through the intelligent regulation of the charging network, during the peak period of electricity consumption, let the new energy vehicles charge less or no charge, and then charge through the intelligent regulation and regulation of the charging network, which can improve the utilization rate of the power grid. Achieve less power consumption in the peak period and more power consumption in the low period, and regulate the load to relieve the pressure of the grid.
④ conducive to the construction of urban smart ecosystem. An important part of the new transportation is the new energy vehicle, which is an important carrier to achieve green transportation. The digital and connected attributes of new energy vehicles themselves can accelerate the development of new transportation modes such as automatic driving, intelligent transportation, and intelligent parking. The "New energy vehicle + charging network" links new energy and new transportation, creating a new industry of two-way integration in the future.
⑤ Promote the development of urban new energy industry. The application innovation of charging network can promote the development of regional new energy industry, increase the share of new energy vehicles, and increase the tax and fiscal revenue of the automobile industry. Promote the process of electrification of buses, e-hailing cars and taxis to provide more travel choices for citizens; It can effectively stimulate the upstream and downstream development of new energy vehicles, such as vehicle production, after-sales maintenance, battery recycling, etc., provide employment opportunities for labor-intensive industries, improve residents' incomes, and achieve social stable development.
⑥ new energy storage consumption, help to achieve carbon neutrality. The new energy vehicle battery can be regarded as an energy storage device, which can charge low-cost new energy electricity such as wind, light and water into the vehicle battery when it is idle, and release the electricity again during the peak period to achieve the "peak shift and valley filling" of the grid.
As a new type of urban infrastructure, the charging industry is showing a new development trend, and the charging service network system is more three-dimensional, which can not only meet the charging of general passenger cars, but also meet the different charging needs of special vehicles, including public transport and logistics.
With the large-scale development of new energy vehicles, the new energy vehicle batteries linked by the charging network will become the largest energy storage network, which will be used to consume new energy electricity such as landscape water, reduce coal burning for power generation, and truly realize new energy vehicle charging new energy electricity.
