At present, solar cells are divided into several types according to the raw materials, structures and manufacturing methods used. Among them, crystalline silicon solar cells mostly refer to monocrystalline silicon solar cells and polycrystalline silicon solar cells using silicon semiconductor substrates as raw materials; In addition, there are amorphous silicon solar cells, which are made by evaporating amorphous silicon on glass substrates rather than silicon substrates based on the same film preparation method as liquid crystal panels. Monocrystalline silicon solar cells form solar cells on monocrystalline silicon substrates, and there are also products with conversion efficiency up to about 20%, which have excellent performance and reliability. However, the price of silicon substrate as raw material is expensive, and the power generation cost per watt is high. Although the conversion efficiency of polycrystalline silicon solar cells is lower than that of monocrystalline silicon solar cells, they have the advantage of relatively low cost.

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.

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.

Charging every day: For many commuters, it may be enough to charge the car once every two or three days. However, some experts suggest that you should not try to save time and charge frequently every day, so that the battery can be in a shallow cycle state, which is more conducive to extending the service life. Pay attention to the phenomenon of poor contact between the plugs at both ends of the charging line: poor contact will lead to the heating of the plug, and once the heating time is too long, short circuit may occur, thus damaging the charger and battery. Therefore, the owner needs to check and replace the connector in time.

At present, the living standard of our people is constantly improving, and the automobile industry is also growing. The car has been basically popular, but with the increase of cars, many problems have also come. Oil is the fuel of traditional cars, not only in China, but also globally, the oil gap in many regions is growing, and the gap will continue to rise in the future. Moreover, the exhaust emissions also cause air pollution. Developing a low-carbon and environmentally friendly economy has always been an economic model advocated by countries around the world. Vigorously developing new energy models not only can protect the environment and save energy, but also new energy technologies are a new round of business opportunities for major enterprises.

Integrated overview: the fast charging pile (plug) equipment adopts the AC/DC integrated structure. It can realize both DC charging and AC charging. When there are many charging services in the daytime, DC mode is used for fast charging. When there are few users in the charging station at night, AC charging can be used for slow charging. Appearance features: 1. Ergonomic design, taking full account of Chinese characteristics, after installation, the height of the whole machine, the height of the screen, the height of the keyboard, and the height of the charging connector slot are suitable for operation; 2. The form of upper outlet saves half of the operator's physical strength; 3. In consideration of people's usage habits and durability, touch and keyboard are mutually backed up. Touch screen and keyboard are designed to be rain proof and dust-proof; 4. Emergency stop switch with emergency stop; The charging connector placement slot is waterproof; 5m long flexible cable.
