Recently, the first "optical storage charging" electric vehicle charging station of Wuhan state grid was put into operation. The integration can convert solar energy into electric energy, and it is a new type of intelligent charging and energy storage equipment. "Optical storage and charging" specifically refers to the use of distributed photovoltaic power generation equipment for energy storage, and then provide power to new energy vehicles for charging. There are 6 sets of 60 kW DC chargers and 1 set of 60 kW dual gun integrated DC chargers in the "optical storage charging" charging station of Chuangye road of State Grid, which can provide charging services for 8 electric vehicles at the same time. Each set is equipped with two charging guns, 16 kilowatt distributed photovoltaic power generation equipment is installed on the ceiling of charging pile, and 64 kilowatt carbon crystal silicon photovoltaic equipment is installed in the office building, which can store 215 kilowatt hours of electricity and provide electric energy for the charging pile of electric vehicles. It is estimated that the annual average generating capacity will reach 88000 kwh, and the annual average carbon dioxide emissions will be reduced by 87736 kg and the coal saved by 2886 kg. According to local reporters in Wuhan, as of September 2019, there are 452 electric vehicle charging stations in Wuhan, of which 73 are operated by the State Grid, and others are from operators of special power, Putian new energy and other brands. There are about 60000 charging piles in the city, and the number of electric vehicles is about 60000. The ratio of vehicles to piles is basically 1:1. Not only in Hubei Province, as early as August 2015, in front of the exhibition hall square of Qinghai Atomic City, there were special parking spaces and charging piles for new energy vehicles using photovoltaic power generation; in September 2017, the "light storage and charging" integrated electric vehicle charging station in Shanghai was equipped with 12 DC charging piles for electric vehicles, which only cost 1.98 yuan for one charge. In case of insufficient sunlight or more charging vehicles in rainy days, the electric vehicle charging station was equipped with 12 DC charging piles In this case, it can also automatically switch to the public grid for power supply. "Shanghai Songjiang" light storage and charging "integrated electric vehicle charging station" and "light storage and charging" special parking space and charging pile for new energy vehicles in Haibei Tibetan Autonomous Prefecture of Qinghai Province "said Yang Fan, deputy general manager of power supply company of Wuhan Zhuankou economic development zone of State Grid," light storage and charging "integrated charging station realizes coordination and support of new energy, energy storage and intelligent charging through" light support pile " 。
