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.

The scheme of the charger in the ground charging station, which is composed of a rectifier that can convert the input AC power into DC power and a power converter that can adjust the DC power. By inserting the plug with wires into the supporting socket on the electric vehicle, DC power is input into the battery to charge it. The charger is equipped with a locking lever to facilitate the insertion and removal of the plug. At the same time, the lever can also provide a signal to confirm that it has been locked to ensure safety. According to the communication between the charger and the on-board battery management system, the power converter can adjust the DC charging power online, and the charger can display the charging voltage, charging current, charging amount and charging cost. This is just the basic principle of the charging pile. Many details should be constantly improved in practical application, and a convenient use scheme has been obtained.

3. Power requirements: ① Input voltage: single-phase 220V; ② Output power: single-phase 220V/5KW; ③ Frequency: 50Hz ± 2Hz; ④ Allowable voltage fluctuation range: single-phase 220V ± 15%; 4. Electrical requirements: ① After the correct connection of plug and socket is confirmed to be successful, the circuit that can be opened and closed with load can be closed to supply power to the socket; ② The leakage protection device shall be installed on the incoming side of the power supply cable; ③ The protection of low-voltage distribution equipment and lines shall meet the relevant provisions in the Code for Design of Low Voltage Power Distribution (GB/50053); ④ For the distribution line of IT system, in case of ground fault, the insulation monitoring device shall send out audio or light signals. In case of the second phase to phase ground fault, the fault circuit shall be cut off by the over-current protection appliance or leakage current action protector; ⑤ In the lighting distribution system, the lighting and socket circuits should not be powered by the same circuit.

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.
