In the future, the charging pile industry will not only be limited to providing charging services, but may also expand to other areas, such as the combination of charging piles with convenience stores, highway rest stops, etc., to further increase the commercial value of the industry.

A research report from Zhongtai Securities shows that there are currently three main categories of domestic charging pile operating entities - the operator-led model, the car company-led model and the third-party charging service platform-led model. Professional operators are the current mainstream operating model for EV charging piles. The four leading operators and platforms, including State Grid, Telecall, Xingxing Charging, and Cloud Quick Charge, account for about 60% of the market share. In terms of car companies, in addition to their early efforts to In addition to Tesla, which has built its own charging piles, NIO, Xpeng Motors, Jikrypton, SAIC-GM-Wuling, etc. are actively deploying public charging piles and opening them to the whole society. Data disclosed by NIO shows that 76% of the electricity is used by non-NIO brands. Among these non-NIO brands, BYD accounts for 17.6%, Tesla accounts for 15.8%, and Xpeng accounts for 4.10%.

As the electric vehicle market continues to expand, the importance of charging piles as infrastructure has become increasingly prominent. By the end of 2022, a total of 5.21 million charging piles and 1,973 battery swap stations have been built across the country, of which 2.593 million new charging piles and 675 battery swap stations will be added in 2022. The construction of charging and swap infrastructure has accelerated significantly. The current barriers faced by the domestic charging pile industry are:

(1) The charging current ranges from 10 amps to 100 amps, which requires high-power charging modules at charging piles.

(2) The lithium-ion batteries used in electric vehicles have strict requirements on overcharge and over-discharge, and the charging device needs to be equipped with a high-precision monitoring system.

(3) At present, the charging station market is basically dominated by the two major power grid companies, State Grid and China Southern Power Grid, and new entrants will face high barriers.

(4) There are still problems such as unreasonable layout of public charging facilities, difficulty in building piles and charging in some residential areas, irregular operation of the charging market, and inadequate maintenance of facilities. The state and local governments have actively introduced a series of industrial encouragement policies. In order to better respond to national policies, they should actively develop DC charging piles and promote the efficient construction and rational layout of charging piles.

(5) The shortcomings of charging infrastructure have become an important factor restricting the development of new energy vehicles.

Operation strategy of charging pile industry
