Expanding the Use of Data Charging Piles —— Development of Electric Vehicles

Construction of charging stations, small charging piles and other facilities can also transform some existing densely distributed gas stations into charging stations. This charging station looks like a gas station, but the investment cost is only 65,438+00% of that of ordinary gas stations, and the safety requirements are lower than those of gas stations.

1, Japan

In Japan, TEPCO, the largest power company in Japan, has close cooperation with automobile manufacturers. Not long ago, a large-scale fast charger was successfully developed, which greatly shortened the charging time and further improved the possibility of popularizing electric vehicles in Japan. TEPCO pointed out that if it is fully charged every 65,438+00 minutes, the distance it can travel is 60 kilometers.

In order to facilitate drivers to charge in the street, it must be promoted through large-scale infrastructure construction projects. At the same time, TEPCO also announced that it will introduce 3,000 electric vehicles based on "environmental protection" and "economy" for commercial and service purposes.

The cost of setting up the charger is 4 million yen. The company plans to build charger equipment in public places such as supermarket parking lots, convenience stores and post offices in Japan. So that people can get off to shop and let the car replenish power when doing things. The Japanese automobile industry believes that electric vehicles are suitable for urban driving, and it is expected that as long as the basic charging equipment is complete, they will soon be accepted by ordinary consumers.

2. Europe

France provides subsidies for the long-term innovation of electric vehicles and their components. The annual budget compiled by the power company headed by EDF exceeds 65,438+0.1billion francs (accounting for 0.05% of the company's operating income), and it is invested in the research and development of batteries and chargers. There are hundreds of chargers in Paris, and all important parking lots are equipped with chargers and special plugs for charging electric vehicles.

Germany also plans to exempt electric vehicle tax and weight tax within five years; Enterprises that develop electric vehicles can enjoy five-year tax exemption. Most charging stations (68%) are completely free, and a few charge charging fees or parking fees.

3. China

In April 2009, Nissan Motor Company established a cooperative relationship with the Ministry of Industry and Information Technology of China. Nissan Motor Co., Ltd. will provide the Ministry of Industry and Information Technology with relevant information on the development of electric vehicles, and formulate a comprehensive plan including establishing and maintaining a battery charging network and promoting the large-scale use of electric vehicles. Wuhan will be the first pilot of Nissan's plan to implement zero-emission vehicles in China. In the future, Wuhan must follow Nissan's standards, which will establish Nissan's dominant position in the competition of electric vehicles.

July 14, 2009 It was reported from Shenzhen that the city may purchase 30 BYD dual-mode electric vehicles as taxis in the future. According to BYD, the power consumption of this F3 dual-mode electric vehicle is 16 kWh, which is about that of 9 yuan. A person in charge of BYD said that BYD has built a number of charging piles in Shenzhen to solve the charging problem of electric vehicles, but the scope is limited to the vicinity of the main city of Shenzhen.

The local policy of Anhui Province also pointed out that in the future, all new buses and taxis in the city will buy hybrid vehicles and pure electric vehicles made in Anhui Province, implement registration management for new energy vehicles that meet the technical conditions of motor vehicle operation safety, reduce and exempt various taxes and fees for new energy vehicles, and support the construction land and supporting funds for electric vehicle charging stations.

2065438+July 2005, Qinghai's first electric vehicle charging station with integrated optical storage was built and put into operation. It is reported that the electric vehicle charging station with integrated light storage is a 20 15 science and technology support project of the Science and Technology Department of Qinghai Province, with a total investment of about 2 million yuan, and it is a permanent charging station. The charging station integrates many advanced technologies such as photovoltaic power generation, intelligent charging piles and energy storage batteries, which breaks through the bottleneck that photovoltaic power stations cannot charge electric vehicles at night.

The electric vehicle charging station with integrated optical storage has an installed photovoltaic capacity of 35kW, a daily power generation capacity of about 200 kWh, an installed energy storage capacity of 150 kw and charging piles of 12, which can provide fast DC charging and slow AC charging services for mainstream electric vehicles at home and abroad. At present, State Grid Qinghai Electric Power Company has built 9 charging stations in Xining, Haibei and Hainan, with 7.2km of 1 0kV line, high pressure ring network cabinet1set, transformer 15 set, 32 slow charging piles of 7kW, 36 fast charging piles of 40kW and fast charging piles of100kW.
