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 relatively expensive. Generally, a 30kw car DC fast charging pile costs about 20,000 yuan, plus construction costs of about 5,000 yuan, which is about 25,000 yuan. It is generally commercial; the price of car slow charging piles is cheaper than DC Many, such as 7kw AC car charging piles are generally around 2000, generally used in homes or underground parking lots, and connected to a power supply of 220V. 1. The construction requirements of automobile charging piles As the automobile charging piles on the power distribution side of the power grid, the particularity of its structure determines that the characteristics of the automated communication system are many and scattered measured points, wide coverage, and short communication distances. And with the development of the city, the network topology requires a flexible and scalable structure. Therefore, the selection of the communication mode of the car charging pile should consider the following issues: 1. Communication reliability——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 smooth. 2. Construction costs——On the premise of satisfying the reliability, comprehensively consider the construction cost and the long-term use and maintenance cost. 3. Two-way communication——Not only can upload the amount of information, but also realize the release of the amount of control. 4. Multi-service data transmission rate——With the continuous growth of terminal traffic in the future, the communication between the main station and the sub-station, and the sub-station to the terminal requires higher and higher data transmission rates to realize multi-service. 5. Communication flexibility and scalability——Since the car charging pile has the characteristics of many control points, wide areas and scattered, it is required to adopt a standard communication protocol.“ALL IP”With the development of network technology trends and the continuous growth of power operation services, it is necessary to consider IP-based service bearer, and at the same time require easy installation, construction, commissioning, operation, and maintenance. 2. Car charging pile operation strategy 1. Sign cooperation station building and operation management agreements with large real estate companies, commercial chain organizations, on-street parking management units designated by the Traffic Management Bureau, and other management units with parking spaces (investors are responsible for putting charging stations and Management, the organization is responsible for providing venues and ensuring safety, charging and value-added benefits are shared by both parties). 2. Carry out joint ventures or apply for funding (policy support in disguise) with relevant government departments (Science and Technology Commission, Science and Technology Association, Urban Construction, Urban Management, Electric Vehicle Leading Group, Economic Commission, Development and Reform Commission, etc.). 3. Joint venture with local departments of State Grid. 4. Joint venture with local branches of large powerful enterprises (CNPC, Sinopec, funds, etc.).
