According to the State Council executive meeting of the "accelerate the construction of electric vehicle charging infrastructure guidance", by 2020 China has basically completed the pile pile, intelligent and efficient charging infrastructure system to meet the needs of more than 5 million electric vehicles charging; 2000 Electric vehicles must be equipped with a public charging station to encourage the construction of integrated mechanical parking charging integration facilities.
But from the current situation, the charge is difficult to promote new energy vehicles is an important bottleneck, in addition, there are a large number of out of the electric vehicle battery pack needs to be addressed. That is, the existing charging mode, the family slow charge need to charge 10 hours, but the fast-charge mode, power at 60-120 kilowatts (KW), charging time is only 1-2 hours.
According to the accounting, slow charging mode requires charging time 8-10 hours, while the charging cost is electricity + service charge 1.8 yuan / degree + parking fee (8-10 yuan / hour) = 140 yuan / times. Beiqi EV160 electric vehicles, for example, charge a power need more than 140 yuan, 120 km battery life, the driving cost of 1.15 yuan / km, much higher than the cost of gasoline vehicles. Slow charging mode of charging a long time, high cost, resulting in a large number of slow filling current idle, no car to charge, the development of fast-filling pile is an inevitable trend.
From the domestic and international situation, the current research and development of China's charging pile of 30 listed companies, 95% of the use of alternating current 380 volts (V) of conventional products, no one developed out of net energy fast charging solar charging pile. In foreign countries are all fast-charge mode, such as the United States Tesla company on the highway to establish hundreds of electric vehicle solar charging stations, completely independent of the grid, all use of solar energy as a source of energy. While Israel, Germany, Japan and other countries also have a large number of new energy charging stations.
Beijing Xinke Shaped Optoelectronic Technology Co., Ltd. said the person in charge of the Beijing Branch of the new photoelectric use of "electric vehicles for charging solar high-voltage DC energy storage device" and other three of its own patented technology, designed the first full-off from the network Type solar power generator energy storage electric vehicle charging station, and in August this year in Dongguan Yu Jia Industrial Park built and put into use. The project through the photovoltaic high-voltage lithium battery pack for DC charging, and then by the high-voltage battery pack to the electric vehicle DC discharge. To avoid the conventional charging equipment, boost, inverter, rectifier, filter and other links, greatly improve the charging efficiency.
