Model diversification: many people find that there are more new energy vehicles running on the street today, and the models are more abundant. Is that the case? By visiting the stores of the three automobile enterprises mentioned above one by one, the reporter found that the product power of new energy vehicles has been greatly improved, and can intuitively feel the strong development momentum of the industry. In Tesla's Beijing Huamao Store, two Model 3 cars are in the middle, and Model Y and Model X of SUV models are on both sides. The three models have the same style, dynamic and fashionable appearance, and simplified interior. The center console has no other physical buttons except for the center control display. From the appearance, the products of the three new energy vehicle brands all have a prominent feature, that is, the design style is fashionable, which is obviously ahead of fuel vehicles at the same price, close to or even beyond international luxury brands. Under the new consumption feature of "beauty is justice", this alone has greatly enhanced the attractiveness of products.

As China joins the ranks of "carbon neutrality", the global carbon emission reduction process continues to accelerate, and new energy vehicles have achieved leapfrog development in the world. Not only are new energy passenger vehicles surging worldwide, many companies in the transportation industry have begun to increase the use of new energy vehicles such as electric buses. New energy charging infrastructure should be taken into the fast lane. Some domestic independent brands began to target overseas markets. Among them, the industry leader TESTU stands out. With advanced products, flexible strategies and rich experience in going to sea, TESTU charging solutions have entered the public transport sector in various places to provide clean energy power for electric buses in many places. The sword is in hand, and the momentum of "winning" is rising

After the completion of charging piles in some places, operation and maintenance become a problem. On the one hand, the number of urban public charging facilities is small, and the distribution is uneven and unreasonable; On the other hand, the management service platforms of the charging infrastructure construction and operation units have not yet achieved interconnection, nor has there been a unified, open and convenient payment platform, which has caused great inconvenience to charging infrastructure users. In addition, in the development process of new energy vehicle industry, there is a widespread problem of focusing on vehicles rather than charging infrastructure. In addition, the national early support policy is mainly aimed at new energy vehicles and does not cover charging facilities. Except for a few cities, most cities have no local subsidies. "This leads to the coexistence of vehicles without piles and piles without vehicles." Moreover, charging infrastructure construction involves urban planning, construction land, distribution network construction and transformation, property management and other aspects, and it is necessary to coordinate multiple competent departments and relevant units in the implementation process.

The increase of power battery capacity of new energy vehicles: the fast charging performance of the power battery determines the ceiling of the fast charging pile. The development of DC fast charging pile requires the cooperation of the power battery. At present, battery manufacturers such as Ningde Times and BYD are trying to improve the energy density of batteries to enhance the endurance. In 2020, the energy density of new pure electric passenger vehicles has basically exceeded 150Wh/kg, and the average endurance mileage has exceeded 400km. The improvement of the endurance mileage of new energy vehicles has improved the practicability of high-power DC public piles, and accelerated the preference of vehicle owners for DC piles, which is the key reason why DC piles will become the choice direction of public piles in the future.
