On board charging device refers to the device installed on the electric vehicle that uses the ground AC power grid and the on-board power supply to charge the battery pack, including the on-board charger (Figure 1-13), the on-board charging generator set and the operating energy recovery charging device. A AC power cable with a plug is directly inserted into the charging socket of the electric vehicle to charge the battery. On board charging devices usually use contact chargers with simple structure and convenient control, or inductive chargers. It is designed completely according to the type of on-board battery, with strong pertinence. Off board charging device, i.e. ground charging device, mainly includes special charger, special charging station, general charger, charging station for public places (Figure 1-14), etc. It can meet various charging modes of various batteries. Generally, the off board charger has large power, volume and weight to adapt to various charging modes.

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.

After the completion of charging piles in some places, operation and maintenance become a problem. On the one hand, the number of urban public charging facilities is small, and the distribution is uneven and unreasonable; On the other hand, the management service platforms of the charging infrastructure construction and operation units have not yet achieved interconnection, nor has there been a unified, open and convenient payment platform, which has caused great inconvenience to charging infrastructure users. In addition, in the development process of new energy vehicle industry, there is a widespread problem of focusing on vehicles rather than charging infrastructure. In addition, the national early support policy is mainly aimed at new energy vehicles and does not cover charging facilities. Except for a few cities, most cities have no local subsidies. "This leads to the coexistence of vehicles without piles and piles without vehicles." Moreover, charging infrastructure construction involves urban planning, construction land, distribution network construction and transformation, property management and other aspects, and it is necessary to coordinate multiple competent departments and relevant units in the implementation process.

What should be paid attention to when charging electric vehicle batteries? When the electric vehicle starts and goes uphill, it is necessary to avoid emergency braking and acceleration as much as possible, because large current discharge will be formed during this process, which will damage the performance of the battery. There are also two points that need special attention when stopping for a long time. 1. Parking without power supply should be avoided: unlike traditional gasoline vehicles, electric vehicles have their own "unique taste" for the state of vehicle parking. If the "hungry stomach" is used too long, it will "rebel". When the electric vehicle is parked in the case of power loss, the battery is prone to sulfation, blocking the electric ion channel, resulting in insufficient charging and declining battery capacity. 2. Deep discharge shall be carried out regularly: when the electric vehicle is almost out of power, undervoltage protection will automatically occur, but during this process, its voltage is unstable, and it will also be up and down, causing repeated undervoltage protection status
