At present, the roadside parking system has been applied in most cities, which can solve the problems of parking difficulties and random parking. The geomagnetic sensor checks the status of the parking space and uploads it to the terminal to facilitate people's travel. The current roadside parking system can not only solve the parking problem, but also provide a new solution for charging new energy vehicles.
Charging piles are arranged in the parking spaces on the roadside, which can temporarily charge electric vehicles. A special point is that the public charging piles are not the user's own. The early charging piles do not have a charging function and are only suitable for household use.
In addition, some tangled problems of the electric meter do not exist in the charging pile. The first is the battery problem. The battery failure of the electric energy meter is very high, and there is no concept of a battery in the charging pile, and no battery is needed. The charging pile loop does not need more than 1,000 data items of State Grid Corporation, only need to pay attention to the instantaneous value of voltage, current, power, etc., only need to pay attention to the single charge. Secondly, when there are some changes in the peak and valley rate, the meter cannot respond, and the charging pile system is only responsible for metering, and the rest is issued by the background system. It is connected to the server through broadband. The server will issue a time and fee for every communication. Rates, charges, etc.
The charging pile equipment itself does not have too high technical content, the standard is unified, the compatibility is good, the quality is stable, and the construction is proper. The difference in competition is mainly reflected in the stability of the production equipment, cost control, brand reputation and appeal.
There are currently four construction and operation modes: official-led, enterprise-led, mixed mode, and crowdfunding mode.
① Officially led: invested and operated by the government. The advantage is strong promotion, but the disadvantage is high capital pressure and low operating efficiency, which may not necessarily adapt to marketization.
②Enterprise-led: invested and operated by enterprises, matched with electric vehicle sales and charging pile production. The advantage is high efficiency of operation and management, but the disadvantage is the lack of unified management, which may cause disorderly competition.
③Mixed mode: the government participates in the support and the enterprise is responsible for the construction. The advantage is that the government and enterprises can complement each other and promote industrial development faster, but the disadvantage is that it is greatly affected by policies.
④ Crowdfunding model: the integration of official, corporate, social and other forces to participate together. The advantage is that it can improve the utilization rate of social resources, adapt to the market, and focus on user needs. The disadvantage is that it is difficult to integrate the interests of all parties, and ultimately it must rely on policy guidance.
