New energy vehicles are the general direction of the development of the automobile industry. However, for electric vehicles, the biggest problem currently facing is not the performance, price, brand problems, but the cruising range and charging problems. The charging problem is not solved, and the development of electric vehicles is Subject to great constraints. At present, China's existing charging piles are mostly mixed models, and what is the ranking of charging pile manufacturers? In this issue, Xiaobian collected relevant data and ranked the main domestic charging pile manufacturers: 1, the function of the charging pile The charging pile is similar in function to the tanker inside the gas station. It can be fixed on the ground or wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can be based on different voltage levels. Charge all types of electric vehicles. The input end of the charging post is directly connected to the AC grid, and the output end is equipped with a charging plug for charging the electric vehicle. The charging pile generally provides two charging modes of conventional charging and fast charging. One can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile, and perform corresponding charging mode, charging time, cost data printing and the like. Charging pile display can display data such as charge amount, cost, charging time, etc. 2. Construction requirements for charging piles As the electric vehicle charging pile on the electric side of the power grid, the particularity of its structure determines that the characteristics of the automatic communication system are that the points to be measured are large and scattered, the coverage is wide, and the communication distance is short. And with the development of the city, the network topology requires a flexible and expansive structure. Therefore, the choice of the communication method of the electric vehicle charging pile should consider the following problems: 1. Reliability of communication - The communication system must withstand the test of harsh environment and strong electromagnetic interference or noise interference for a long time, and keep the communication smooth. 2, construction costs - on the premise of meeting the reliability, comprehensive consideration of construction costs and long-term use and maintenance costs. 3, two-way communication - not only can achieve the upload of information, but also to achieve the release of control. 4. Data transmission rate of multi-services - With the continuous increase of terminal traffic, the communication between the primary station and the sub-station and the sub-station to the terminal has higher and higher requirements for realizing the data transmission rate of multiple services. 5, communication flexibility and scalability - because the charging pile has many features of control points, wide and scattered, requires the use of standard communication protocols, with the development of "ALLIP" network technology trends and power operations Growing, you need to consider IP-based service bearers, and at the same time require easy installation, commissioning, operation, and maintenance. 3. Safety requirements for charging piles 1. The substation should be equipped with a safety fence, warning signs, safety lights and alarm bells. 2. The “stop, high voltage danger†warning sign should be hung on the safety fence of the high voltage power distribution room and the transformer room or the substation. The sign of the warning sign must face the outside of the fence. 3. There should be significant operating instructions on the high-voltage power distribution unit. The grounding point of the equipment should have a clearly visible mark. 4. There should be obvious “safe passage†or “safe exit†signage in the room. In addition, the layout of substations and distribution equipment should be easy to install, operate, transport, overhaul, test and monitor. High and low voltage distribution rooms, transformer rooms, capacitor rooms, and control rooms should not have pipes and lines that are not related to them. Of course, even if the technical bottleneck of the charging station is well solved, the construction of the charging station may still have problems such as difficulty in site selection. New energy vehicles should be dominated by cities first, but the prosperous areas are often tightly landed and the land price is high. This requires the government to tilt the policy and promote the construction of charging facilities. The development and operation of electric vehicle charging stations by power companies has inherent advantages. It is a new business for power companies to sell electricity directly to vehicles, and it is hoped that power companies will be able to transform. 4. Future development of charging piles It is estimated that the direct market size of domestic energy vehicle charging piles (station) in the next five years is expected to reach 126 billion yuan; the annual profit of the charging pile (station) industry can reach 1.8 to 2.7 billion yuan. With charging pile enterprise ranking: 1. Ranked by 2015 shipments: 2. Ranked according to the installed capacity in 2015: 3. According to the operating income in the first half of 2015: 4. Charging pile listed company's profit ranking in the first half of 2016: At present, there are more than 300 charging pile companies in China. The whole industry is in a period of rapid development, especially the planned capacity of 5 million in 2020. The overall development of the charging pile industry is good, and there is no rumor that the company has closed down. In recent years, the market is still in the early stage of development. Whether it is new construction or renovation, the diversity of the main players involved, there are still many uncertainties in the future charging pile industry. The heroes are competing, who is up and down?
