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.

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.

Small electric vehicles are different from traditional gasoline vehicles. What should we pay attention to during maintenance? For electric vehicles, the battery acts as its "heart", controlling the forward power of the vehicle. Especially in the charging process, we need to pay special attention! Common sense of electric vehicle charging: batteries should not be overcharged or discharged too much: overcharge and discharge of batteries will reduce their service life. Overcharging will cause the battery to heat up, which may cause spontaneous combustion, explosion and other hazards in serious cases. While driving, if the electricity meter indicates the red light area, the driver needs to stop running and charge as soon as possible, otherwise the battery loss rate will greatly increase in the long run. It is understood that the average charging time of the general battery is about 10 hours. The charging time should be well controlled. If the battery temperature exceeds 65 degrees, the charging should be stopped.

Any problems arising from development must be solved with a development perspective and innovative practice. By innovating the operation mode of "mixed ownership", Shenzhen has solved the problem of "one kilometer after Z" in the promotion of new energy public transport, and the measures to realize the pure electrification of exclusive public transport are worthy of reference for the industry. "The charging pile has a large capital investment and rapid technology update. Without the intervention of companies with technical reserves and market power, it would be difficult for enterprises to survive." As one of the top three bus companies in Shenzhen, Yu Gang, the chairman of Shenzhen Bus Group, has a deep understanding of the "charging pile problem" encountered in the promotion of pure electric bus. Yu Gang introduced that the public transport group in a city in China had invested more than 200 million yuan to build 200 charging piles, each charging pile cost about 1 million yuan, 2-3 times the market price. Z could not recover the cost at last, and because it could not keep up with the technology update, many equipment was currently idle.

The increase of power battery capacity of new energy vehicles: the fast charging performance of the power battery determines the ceiling of the fast charging pile. The development of DC fast charging pile requires the cooperation of the power battery. At present, battery manufacturers such as Ningde Times and BYD are trying to improve the energy density of batteries to enhance the endurance. In 2020, the energy density of new pure electric passenger vehicles has basically exceeded 150Wh/kg, and the average endurance mileage has exceeded 400km. The improvement of the endurance mileage of new energy vehicles has improved the practicability of high-power DC public piles, and accelerated the preference of vehicle owners for DC piles, which is the key reason why DC piles will become the choice direction of public piles in the future.
