In addition, according to the different ways of energy conversion when charging the electric vehicle battery, charging devices can be divided into contact type and induction type. With the rapid development of power electronics technology and converter control technology, the maturity and popularization of high-precision controllable converter technology, the phased constant current charging mode has been basically replaced by the constant voltage current limiting charging mode with continuous changes in charging current and charging voltage. The constant voltage current limiting charging mode dominates the charging process. The big problem of contact charging is its safety and versatility. In order to make it meet the strict safety charging standard, many measures must be taken in the circuit to enable the charging equipment to charge safely in various environments. Constant voltage current limiting charging and phased constant current charging are both contact charging technologies. New induction charging technology for electric vehicles has developed rapidly.

Nezha Auto, whose products focus on middle and low-end models, delivered 10127 new cars in December, a year-on-year increase of 236%, with monthly sales exceeding 10000 yuan. In 2021, Nezha Auto delivered 69674 units, a sharp increase of 362% year on year. According to official data, in 2021, about 64% of Nezha's users will come from first tier, new first tier and second tier cities - which means that nearly 40% of Nezha's users will come from third tier, fourth tier and fifth tier cities, or sinking markets. In addition, it is worth noting that the high-end new energy sub brands of Landu Auto and Krypton, two traditional car companies, both exceeded 3000 vehicles in December. Although the number is not large, for a new brand that has only been established for a year or two and has only been delivered for a few months, the deeper meaning is to get through the process. The next step is to continue to expand production capacity and sales channels.

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;

When the charging post is built, it should be used and managed well. The implementation of management responsibility and clear operation mode can make the charging pile safe and reliable. At present, the charging pile is faced with the problem of unclear management responsibility and unclear operation mode. There are some problems such as the aging of distribution facilities in the community, who will pay for the reconstruction, the quality of piles is mixed, and who will solve the hidden fire hazards. The same is true of public charging posts. There are not many DC fast charging piles with high investment standards and high power, but "problem piles" and "zombie piles" are common. In recent years, the number of charging pile construction and operators in China has grown rapidly, but the level of enterprises is uneven.

Any problems arising from development must be solved with a development perspective and innovative practice. By innovating the operation mode of "mixed ownership", Shenzhen has solved the problem of "one kilometer after Z" in the promotion of new energy public transport, and the measures to realize the pure electrification of exclusive public transport are worthy of reference for the industry. "The charging pile has a large capital investment and rapid technology update. Without the intervention of companies with technical reserves and market power, it would be difficult for enterprises to survive." As one of the top three bus companies in Shenzhen, Yu Gang, the chairman of Shenzhen Bus Group, has a deep understanding of the "charging pile problem" encountered in the promotion of pure electric bus. Yu Gang introduced that the public transport group in a city in China had invested more than 200 million yuan to build 200 charging piles, each charging pile cost about 1 million yuan, 2-3 times the market price. Z could not recover the cost at last, and because it could not keep up with the technology update, many equipment was currently idle.
