At present, China's electric vehicle industry has just started, and the number of electric vehicles put into use is relatively small. The number of electric vehicles in the country is not more than 10,000. We rarely see electric vehicles on the road. The electric vehicle charging station is a charging station set up to facilitate the timely charging of electric vehicles. So, in the future, what is the market prospect of electric vehicle charging stations? As a kind of motor vehicle with lower energy consumption and less emissions, electric vehicles are strongly advocated and promoted worldwide. In China, the development of electric vehicles is an inevitable trend and will gradually become popular in the future. In order for an electric car to enter the homes of ordinary people, it must have a very convenient energy supply station, that is, an electric vehicle charging station. Many new energy companies are currently promoting the construction of electric vehicle charging stations to seize market opportunities. According to the research report of relevant agencies, in the next five years (2016-2020), the market size of China's electric vehicle charging stations will have an annual growth rate of 115%. Especially in some large and medium-sized cities, such as Shanghai, Hong Kong, Shenzhen, Beijing, Guangzhou and Jiangsu, in order to cope with the intensified air pollution, the monitoring of the emission of carbon dioxide and particulate matter from vehicle exhaust gas is becoming increasingly stringent. Therefore, the government's leading role in the promotion of electric vehicles is a general trend, and electric vehicle charging stations also have the main driving force for development. The market development trend of energy conservation and emission reduction has made electric vehicles and electric vehicle charging stations have more optimistic prospects, and the industry has higher investment value. At present, many large automotive R&D companies and energy companies at home and abroad have tested the electric vehicle industry, such as BYD, ABB Switzerland, and Hong Kong Electric Energy Company. However, the construction of electric vehicle charging stations cannot be completed in the short term. The main reason is that electric vehicles must be charged quickly and must have instantaneous and powerful high-power power. The conventional power grid cannot meet the requirements at all and must be built specifically for car charging. Charging network. Therefore, the construction of an electric vehicle charging station requires the transformation of the entire power supply network, which not only costs huge capital, but also has a long construction period.
