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

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 piles are the inevitable choice of public piles in the future: at present, the proportion of public AC and DC charging piles remains around 6:4, and the proportion of AC piles is more, mainly because in the early stage of the industry development, slow charging AC piles are very suitable for manufacturers to seize the market, relying on the characteristics of simple structure, mature technology and low cost, However, after the technology and market of charging piles become mature, DC piles are the inevitable choice for future public charging piles. The average charging time of the DC charging pile is 1 hour and 54 minutes. 85% of the users can finish charging within 2.5 hours, while the average charging time of the AC charging pile is 5 hours and 45 minutes. 66.2% of the users need more than 5 hours of lengthy charging time. The difference between the two nearly 4 hours of time directly determines the obvious use preference of the car owner Z.

How to properly charge in the hot link when using the charging pile of new energy vehicles? 1. Take care of your electric donkey and don't let it get sunburnt: in hot summer, you often sweat, and the rechargeable battery often "gets high fever". Here, it is recommended that the owner choose a place with a parking shed or a barrier to cover the electric vehicle as far as possible, and don't let the electric vehicle be exposed to the sun immediately, which will endanger the service life of the vehicle. In addition, fire accidents are very likely to occur under high temperatures. 2. Do not "steam up and cook down": the temperature is already hot. If the electric car is exposed to the sun at the moment, but you are charging the car, the rechargeable battery will generate heat in the whole process of charging. At this time, all cars are in the "steam up and cook down" mode, and you will "deploy" carelessly. 3. The electric vehicle must also take a proper "rest". 4. The charging time must be well controlled.

6. Safety protection function: ① The AC charging pile (bolt) shall be equipped with an emergency stop switch, which can be used to stop charging manually or by remote communication; ② The AC charging pile (bolt) shall have the leakage protection function at the output side; ③ AC charging pile (plug) shall have output side overcurrent and short circuit protection functions; ④ AC charging post (bolt) shall have flame retardant function; 7. IP protection level: AC charging pile (plug) shall comply with IP54 (outdoor), and be equipped with necessary rain proof and sun protection devices; 8. Three proofing (anti moisture, anti mildew, and anti salt fog) protection The printed circuit board, connector and other circuits in the charger shall be treated against moisture, mildew, and salt fog. The salt fog corrosion resistance shall meet the requirements in Table 9 of GB/T 4797.6-1995 Natural Environmental Conditions for Electrical and Electronic Products Dust, Sand, and Salt Fog, so that the charger can be wet Normal operation in the environment with salt fog;
