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.

In fact, in order to effectively develop the new energy vehicle industry, in addition to the problems exposed in the construction of charging piles, such as difficult site selection, power connection and property coordination, the integration of infrastructure resources, the unification of public charging facilities information platform, the standardization of charging interfaces, and the billing and settlement in the charging process also need to be solved. The charging infrastructure of new energy vehicles is a new type of urban infrastructure. Its construction is a systematic project involving land, power grid, electricity price, mechanism and many other links, which is also the reason why the charging infrastructure construction is relatively difficult. However, as long as the relevant parties meet each other and reach consensus, instead of talking to themselves and going their own way, these problems will eventually be solved.

The scheme of the charger in the ground charging station, which is composed of a rectifier that can convert the input AC power into DC power and a power converter that can adjust the DC power. By inserting the plug with wires into the supporting socket on the electric vehicle, DC power is input into the battery to charge it. The charger is equipped with a locking lever to facilitate the insertion and removal of the plug. At the same time, the lever can also provide a signal to confirm that it has been locked to ensure safety. According to the communication between the charger and the on-board battery management system, the power converter can adjust the DC charging power online, and the charger can display the charging voltage, charging current, charging amount and charging cost. This is just the basic principle of the charging pile. Many details should be constantly improved in practical application, and a convenient use scheme has been obtained.
