·The new energy vehicle charging pile standard in the Yangtze River Delta will be unified

The Yangtze River Delta teamed up to tackle the problem and add innovative and pragmatic measures. The reporter learned from the 16th Mayor's Joint Meeting of the Yangtze River Delta Urban Economic Coordination Meeting held by Jinhua that the three provinces and one city in the Yangtze River Delta, which accounted for one-third of the national new energy vehicle market, jointly initiated the establishment of the Yangtze River Delta New Energy Vehicle Development Promotion Alliance. It is committed to cracking the charging infrastructure charging compatibility, transaction payment interconnection and other issues.
At present, the new energy automobile industry is standing at the “window”. The main leaders of the three provinces and one city in the Yangtze River Delta last year also decided to promote the low-carbon development of transportation facilities in the Yangtze River Delta. From the actual situation, the capital of the new energy vehicle market is surging, and it is frequently used. As of the end of last year, the number of charging piles that have been built in the Yangtze River Delta has exceeded 37,000, accounting for more than 70% of the national total. Moreover, the charging pile facilities will continue to show a surge. Take Shanghai as an example. According to the “Shanghai Special Plan for Electric Vehicle Charging Infrastructure (2016-2020)”, Shanghai New Energy Vehicle Charging Pile will increase by at least 212,000 on the basis of the existing 21,700 units in 2020. Other cities are also making rapid efforts in the field of new energy vehicles. At present, more than 90% of buses in Hangzhou are new energy vehicles. At the end of this year, the remaining buses in Hangzhou will all be updated to new energy vehicles.
However, at the same time of rapid development, the problem is also prominent. According to the research report of the China Electric Vehicles 100 People's Association, there are currently large differences in the existing charging pile standards in the Yangtze River Delta. The charging infrastructure operators lack consensus on the unified payment methods, and there are also concerns about the interconnection and interconnection of public platforms. In addition, vehicle companies have concerns about data opening, and many problems directly lead to difficulties for owners to find, difficult to charge, and difficult to pay, and inhibit the enthusiasm of the new energy vehicle consumer market.
Liu Jianhua, director of the Shanghai New Energy Vehicle Promotion Office, told reporters that at the beginning of the year, the state introduced five national standards for electric vehicle charging interfaces and communication protocols, but these standards are recommended standards. At present, there are different understandings of standards in the industry, which leads to the presented There are differences in product compatibility. Therefore, it is particularly necessary to take the lead in reaching a standard consensus in the three provinces and one city of the Yangtze River Delta, which accounts for one-third of the national new energy vehicle market. Alliance Initiative: The Yangtze River Delta New Energy Alliance cities should open a fair use environment, encourage fair competition; unify charging pile standards; promote new energy vehicle charging mode, and jointly promote the development of the Yangtze River Delta micro-bus and time-sharing business; Long-term mechanism, the establishment of the Yangtze River Delta New Energy Promotion Alliance. According to Yao Hai, director of the Shanghai Cooperation and Exchange Office and secretary general of the Yangtze River Delta Urban Economic Coordination Committee, the alliance will unite 30 cities in the Yangtze River Delta to leverage the “Internet +” to promote the development of time-sharing and micro-bus.

Air Compressor

As you can see our selection of air compressors including portable air compressors, small air compressors, electric & gas air compressors and much more.

An air compressor is a device that converts power (using an electric motor, diesel or gasoline engine, etc.) into potential energy stored in pressurized air (i.e., compressed air). By one of several methods, an air compressor forces more and more air into a storage tank, increasing the pressure. When the tank's pressure reaches its engineered upper limit, the air compressor shuts off. The compressed air, then, is held in the tank until called into use.


The energy contained in the compressed air can be used for a variety of applications, utilizing the kinetic energy of the air as it is released and the tank depressurizes. When tank pressure reaches its lower limit, the air compressor turns on again and re-pressurizes the tank. An air compressor must be differentiated from a pump because it works for any gas/air, while pumps work on a liquid.


It mainly used in a lot of drilling fields, such as Water Well Drilling Rig in rocky layer,DTH Drilling Rig in rock works,underground jumbo drilling rig,percussion drilling piling rig,Core Drilling Rig in geological investigation and so on.
