Charging or changing? It is difficult to break through the pain points of the construction of power exchange stations: the construction speed of power exchange stations is amazing. From August 2019 to December 2020, the number of power exchange stations has increased from 245 to 734 in more than a year. The top three operators are respectively Aodong, Weilai and Botan, 286, 175 and 94. The electric vehicle power change mode refers to the centralized storage, charging and distribution of a large number of batteries through a centralized charging station, and the battery replacement service for electric vehicles in the battery distribution station or the integration of battery charging, logistics allocation and power change services. However, the pain point of the power exchange mode is still the bottleneck that is difficult to break through.

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.

Both the mileage and the number of charging posts have made great progress over the previous years. According to the reporter, at present, the driving range of the mainstream models of new energy vehicles and passenger vehicles in China has reached more than 300 kilometers, which is in line with the international advanced level. The energy density of the single power battery of the leading enterprise has reached 2 watt hours per kilogram, and the price has reached 1.2 yuan per watt hour. These two indicators have respectively increased by two times and decreased by 70% compared with 2012. At the same time, the construction of charging network is progressing steadily, and the coverage of public places, residential quarters, internal units, highways and other major places is increasing significantly. By the end of 2017, 214000 public piles had been built nationwide, an increase of 51% year on year, ranking first in the world in terms of ownership, and the installation rate of new users' private piles exceeded 80%.

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.

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.
