According to the new national standard, the charging plug standard of different models in the future is the same. Xu Xinchao said, "Although there will be differences in voltage and power, theoretically it can be used in the same charging point. In addition, the new national standard attaches particular importance to the safety of the charging pile, which has always been the top priority. The standardized charging pile of new energy vehicles will automatically cut off power after charging, making breakthroughs in insulation and avoiding electric shock in rainy days, so as to avoid unnecessary dangers for new energy owners during charging.

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 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, 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 charging pile industry comes with the development of new energy vehicles. In 2020, the charging pile will be included in the new infrastructure and written into the government work report, which will become the precondition for developing new energy vehicles, stimulating new consumption demand and helping the industry upgrade. Under the exploration of new business model and the guidance of a new round of policies, new channels for the development of charging piles have been opened, ushering in new opportunities. The charging pile industry chain is divided into supply terminals such as equipment manufacturers and power suppliers, operation terminals such as operators and new energy vehicle enterprises, and support terminals such as map navigation and payment functions. The core link is the operation end, which is responsible for the investment, construction and operation management of the charging pile. At present, Chinese funded enterprises, private capital and vehicle enterprises are all involved in the operation.
