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.

Over the past few years, China's new power vehicles have entered a new stage of development. Compared with the previous two years, its functions have entered a new stage. The environmental trend of new power vehicles has become more mature. Since the launch of new power vehicles, the national policy has been continuously supported, and friends have gradually taken over the new power vehicles, But do friends inquire about new power cars? The following editor will explain to friends what the policy of charging pile for new power vehicles is! Description of new power vehicle charging pile policy - brief introduction The threshold of awards for the city of atmospheric pollution in 2016-2020 The number of new power vehicles promoted is divided into no less than 30000, 35000, 43000, 55000, 70000, and the number of new power vehicles promoted accounts for no less than 3%, 4%, 5%, 8%, and 10% of the total number of new and updated vehicles in the inland area.

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.

On board charging device refers to the device installed on the electric vehicle that uses the ground AC power grid and the on-board power supply to charge the battery pack, including the on-board charger (Figure 1-13), the on-board charging generator set and the operating energy recovery charging device. A AC power cable with a plug is directly inserted into the charging socket of the electric vehicle to charge the battery. On board charging devices usually use contact chargers with simple structure and convenient control, or inductive chargers. It is designed completely according to the type of on-board battery, with strong pertinence. Off board charging device, i.e. ground charging device, mainly includes special charger, special charging station, general charger, charging station for public places (Figure 1-14), etc. It can meet various charging modes of various batteries. Generally, the off board charger has large power, volume and weight to adapt to various charging modes.
