Small electric vehicles are different from traditional gasoline vehicles. What should we pay attention to during maintenance? For electric vehicles, the battery acts as its "heart", controlling the forward power of the vehicle. Especially in the charging process, we need to pay special attention! Common sense of electric vehicle charging: batteries should not be overcharged or discharged too much: overcharge and discharge of batteries will reduce their service life. Overcharging will cause the battery to heat up, which may cause spontaneous combustion, explosion and other hazards in serious cases. While driving, if the electricity meter indicates the red light area, the driver needs to stop running and charge as soon as possible, otherwise the battery loss rate will greatly increase in the long run. It is understood that the average charging time of the general battery is about 10 hours. The charging time should be well controlled. If the battery temperature exceeds 65 degrees, the charging should be stopped.

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 control circuit of the electric vehicle charging pile (plug) is mainly completed by the embedded ARM processor. Users can swipe their cards to carry out user authentication, balance query, billing query and other functions, and can also provide voice output interface to achieve voice interaction. The user can select four charging modes according to the indication of the LCD screen: charging on time, charging according to the quantity of electricity, automatic charging, charging according to the mileage, etc. The electric vehicle charger controller and concentrator use CAN bus for data interaction, and the concentrator and server platform use wired Internet or wireless GPRS network for data interaction. For security reasons, the electricity billing and amount data are encrypted securely.

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

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.
