How much is a set of car charging piles

How much is a set of car charging piles? At present, car charging piles are generally divided into two types, DC and AC, and their prices are also different. Car DC Fast Charging piles are more expensive. Generally, a 30kw car DC fast charging pile costs about 20,000 yuan, plus the construction cost is about 5,000 yuan, which is almost 25,000 yuan. It is generally commercial; the price of slow car charging piles is cheaper than DC Many, such as 7kw AC car charging piles, are generally around 2000, and they are used in general households or underground parking lots, and they are connected to power 220V.

1. Construction requirements for car charging piles
As the vehicle charging pile on the power distribution side of the grid, its structure determines that the automatic communication system is characterized by many and scattered points, wide coverage, and short communication distance. And with the development of the city, the network topology requires a flexible and expandable structure. Therefore, the following issues should be considered when selecting the communication mode of the car charging pile:
1. The reliability of communication-the communication system must withstand the test of harsh environment and strong electromagnetic interference or noise interference for a long time, and keep the communication unblocked.
2. Construction costs-on the premise of satisfying reliability, comprehensive consideration of construction costs and long-term use and maintenance costs.
3. Two-way communication-not only can upload the amount of information, but also realize the release of the control amount.
4. Multi-service data transmission rate-With the continuous growth of terminal business volume in the future, the communication between the master station to the sub-station and the sub-station to the terminal requires higher and higher data transmission rates for the realization of multiple services.
5. Communication flexibility and scalability-because the car charging pile has the characteristics of multiple control points, wide coverage and decentralization, it requires the use of standard communication protocols. With the development of the "ALL IP" network technology trend and power operation With the continuous growth of services, it is necessary to consider IP-based service bearer, and at the same time require easy installation, construction, commissioning, operation, and maintenance.

2. Operation strategy of car charging piles
1. Sign cooperative station construction and operation management agreements with large real estate companies, commercial chain institutions, roadside parking management units designated by the Traffic Management Bureau, and other management units with parking spaces (the investor is responsible for charging stations and management, and the institution is responsible for providing venues and To ensure safety, charging and value-added benefits are shared by both parties).
2. Cooperate with relevant government departments (Science and Technology Commission, Association for Science and Technology, Urban Construction, Urban Management, Electric Vehicle Leading Group, Economic Commission, Development and Reform Commission, etc.) or develop joint ventures or apply for funding (disguised policy support).
3. Joint operation with local departments of State Grid.
4. Joint operation with local branches of large powerful enterprises (CNPC, Sinopec, funds, etc.).
