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.

DC piles are the inevitable choice of public piles in the future: at present, the proportion of public AC and DC charging piles remains around 6:4, and the proportion of AC piles is more, mainly because in the early stage of the industry development, slow charging AC piles are very suitable for manufacturers to seize the market, relying on the characteristics of simple structure, mature technology and low cost, However, after the technology and market of charging piles become mature, DC piles are the inevitable choice for future public charging piles. The average charging time of the DC charging pile is 1 hour and 54 minutes. 85% of the users can finish charging within 2.5 hours, while the average charging time of the AC charging pile is 5 hours and 45 minutes. 66.2% of the users need more than 5 hours of lengthy charging time. The difference between the two nearly 4 hours of time directly determines the obvious use preference of the car owner Z.

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.

The function of the charging post is similar to that of the gas dispenser in the gas station. It can be fixed on the ground or wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations, and can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected with the AC power grid, and the output end is equipped with a charging plug for charging the electric vehicle. Generally, the charging pile provides two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to print the corresponding charging method, charging time, cost data and other operations. The charging pile display screen can display the charging amount, cost, charging time and other data.

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.
