Analysis of charging pile industry for new energy vehicles

A particularly easy-to-understand truth: a glass of water, not filled with some water, will not necessarily overflow, but if you are not satisfied with a full glass of water, it will definitely overflow. In the past two years, the development speed of new energy vehicles is obvious to all. Now, new energy vehicles have become one of the leading industries in China and even the world. China's new energy production and sales reached 794,000 vehicles and 777,000 vehicles respectively, reaching 6.5438+0.8 million vehicles, accounting for more than 50% of the global market share, ranking first in the world for three consecutive years. 90% of new energy vehicles are electric vehicles to be charged, so charging facilities have become a vital infrastructure for the development of new energy vehicles. At the same time, charging facilities have also become the biggest shortcoming that restricts the rapid advancement of new energy vehicles. Let's take a look at the analysis of this vehicle system on the charging pile industry of new energy vehicles.

Classification analysis of charging piles in new energy vehicle charging pile industry

According to the different charging power, charging piles can be divided into DC fast charging and AC slow charging. AC charging pile is a power supply device that is fixedly installed in community parking lots, residential quarters, large shopping malls, service areas, roadside parking lots and other places, and connected to the power grid to provide controllable unidirectional AC power supply or three-phase AC power supply for electric vehicle chargers. The AC charging pile itself has no charging function, it only provides power output, and it is also connected to the on-board charger of the electric vehicle to charge the battery of the electric vehicle. Because most of the power in electric car charger is quite small, AC charging piles can't be charged quickly. DC charging piles are also fixed charging devices installed outdoors, such as community parking lots, residential quarters, large shopping malls, service areas, roadside parking lots, special charging stations for electric vehicles and other places, which are connected to the power grid to provide DC power for electric vehicle batteries. Because DC charging piles can directly charge the batteries of electric vehicles, most of them use three-phase four-wire system or three-phase three-wire system for power supply, and the output voltage and current can be adjusted in a wide range, which can quickly charge electric vehicles. Simply put, because lithium batteries must be charged by DC, DC charging piles can directly convert electric energy from AC to DC, while AC charging piles need to complete the conversion process of on-board chargers of electric vehicles, which are limited by the size of on-board chargers, and most of them have low power and slow charging speed.

Analysis and practical problems of automobile new energy charging pile industry

In the past two years, the year-on-year lag of basic supporting facilities such as charging piles has become increasingly prominent. Although the number of charging piles is growing rapidly, it cannot be ignored that the growth scale of new energy vehicles is still much higher than that of charging piles, which means that the gap between piles is still widening. By the end of the year, about 2 1 1,000 public charging piles have been built in China, and the ratio of total vehicles to piles is about 8: 1, which is far from meeting the normal charging demand of new energy vehicles. In addition, according to the survey, whether the configuration of charging piles is complete, whether charging is convenient enough, and whether it is feasible to install charging piles by themselves are all crucial factors that users need to worry about when buying electric vehicles. Therefore, we believe that the mature development of the charging pile industry is the basis for the further development of new energy vehicles. The further maturity of new energy vehicles will also promote the development of the charging pile industry. They promote each other, complement each other and are inseparable.

Analysis and development trend of automobile new energy charging pile industry

With the explosive growth of the number of new energy vehicles in recent two years, the construction scale of charging piles in supporting facilities has also expanded accordingly. During the seven years from 20 10 to 2007, the number of charging piles in China increased from more than 1000 to 2 10000. 20 15, 110/0. In October, the National Development and Reform Commission, the Energy Bureau, the Ministry of Industry and Information Technology and the Ministry of Housing and Urban-Rural Development jointly issued the Guide for the Development of Electric Vehicle Charging Infrastructure (20 15-2020), which clearly stated that by 2020,

The disadvantage of new energy vehicles is that it is difficult to charge. If this thorny problem can be solved, everyone will be very happy. In the future, we can imagine that there is a higher level of energy in the current new energy. As far as the development law of the industry is concerned, the explosion of technology is not impossible, but now, new energy still has a long way to go. Whether it is technical requirements such as more efficient energy storage batteries, faster and safer charging schemes, or the development of a better profit model, it basically needs the concerted efforts of all practitioners, and there is a long way to go. The above is the analysis information of new energy vehicle charging pile industry shared by Bian Xiao Auto.
