Guiyang Electric Vehicle Maintenance Project
In this environment, major automobile manufacturers in the automobile industry are also constantly shifting their focus to the research and development of new energy vehicle technology, and have also launched many new energy vehicles to replace oil with electricity and reduce emissions. This also represents the new direction of future automobile development. In China, friends who pay more attention to cars can see that more and more new energy vehicles are running on the road. More people are also aware of the benefits that new energy vehicles bring to the earth. The country is also introducing various preferential policies to vigorously promote the development of new energy vehicles. However, the main reason why some people are unwilling to buy new energy vehicles is the lack of endurance and inconvenient charging. However, with the continuous popularity of electric vehicles, these problems will certainly be solved in the future. Previously, the country also made a series of decisions in order to facilitate the charging of cars in the future.

DC type: a) Power input voltage of charging pile (plug): three-phase four wire 380VAC ± 15%, frequency 50Hz ± 5%; b) The charging pile (plug) shall meet the charging object; c) The output of the charging pile (plug) is DC, and the output voltage meets the battery system requirements of the charging object; d) Zui's large output current meets the charging requirements of battery system 1C of the charging object, and is downward compatible; e) The charging mode can be divided into conventional and fast charging modes. The conventional charging mode is 5-hour charging mode, and the fast charging mode is 1-hour charging mode (selected for different battery types); f) Realize intelligent IC management; g) Each charging pile (plug) is equipped with an operator for the user to select charging mode and guide operation, and display the battery status of electric vehicles and the user's IC card charge information to achieve unattended management;

Integrated overview: the fast charging pile (plug) equipment adopts the AC/DC integrated structure. It can realize both DC charging and AC charging. When there are many charging services in the daytime, DC mode is used for fast charging. When there are few users in the charging station at night, AC charging can be used for slow charging. Appearance features: 1. Ergonomic design, taking full account of Chinese characteristics, after installation, the height of the whole machine, the height of the screen, the height of the keyboard, and the height of the charging connector slot are suitable for operation; 2. The form of upper outlet saves half of the operator's physical strength; 3. In consideration of people's usage habits and durability, touch and keyboard are mutually backed up. Touch screen and keyboard are designed to be rain proof and dust-proof; 4. Emergency stop switch with emergency stop; The charging connector placement slot is waterproof; 5m long flexible cable.

Safety requirements (1) The substation shall be equipped with safety bulletin board, warning board, safety signal light and alarm bell. (2) The warning sign of "Stop, High Voltage Danger" shall be hung outside the door of the high-voltage distribution room and transformer room or on the safety column of the substation. The warning signs must face the outside of the fence. (3) There shall be obvious operation instructions on the high-voltage distribution device. The grounding point of the equipment shall have obvious signs. (4) There should be obvious signs of "safe passage" or "emergency exit" in the room. In addition, the layout design of substation and distribution equipment shall facilitate installation, operation, handling, maintenance, test and monitoring. High and low voltage distribution room, transformer room, capacitor room and control room should not have unrelated pipes and lines passing through. New energy vehicles should first focus on cities, but the busy IX region is often short of land, and the cost of land is high. In this regard, the government needs to give preferential policies to promote the construction of charging facilities. The development and operation of electric vehicle charging stations by electric power enterprises have inherent advantages.
