How to make money by investing in charging piles? In recent years, the investment in charging piles has become more and more popular. As of July 2021, the number of public charging posts nationwide will be 950000, a high growth of 67.85% year on year, and the charging power will increase by 44% year on year. So, is this the right time for operators who are investigating the charging pile market or preparing to invest in construction? The answer is yes. Under the background of "dual carbon", the new energy vehicle market is a huge market with continuous growth, belongs to the blue ocean market, and is rigid demand. The investment threshold is relatively low compared with gas stations. Since the market is so good, why can't many charging stations make money? At present, the main profit sources of charging piles are service fees, power price difference and value-added services.

Why does the new energy vehicle suddenly "break the circle" and make many consumers "turn into fans"? Compared with traditional fuel vehicles, what are the unique attractions of new energy vehicles for consumers? What are the characteristics and differences in products, marketing and services of different automobile enterprises? With these hot topics in mind, the reporter recently selected three enterprises in the high-end field of new energy vehicles, namely Tesla, Weilai and BYD New Energy stores in Beijing for experiential interviews to observe the changes of new energy vehicles in product power, price, marketing and service from the perspective of consumers. I hope to read with readers the reasons behind the unexpected growth of the new energy vehicle industry in the middle and high-end field, which is the "race track" of new energy vehicles.

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.
