New energy vehicle charging pile It is divided into DC fast charging and AC charging. Generally speaking, fast charging is DC charging, and slow charging is AC charging. DC fast charging is mainly set in large charging stations, which are connected to the power grid in the form of three-phase four wire system to provide sufficient power. The output voltage and current can be adjusted in a wide range. Generally, it takes 1.5~3 hours to charge batteries with DC charging piles, and 8~10 hours to charge batteries with AC charging piles. In the future, the development of new energy will also continue to improve, Electric vehicle charging pile Is it worthwhile for entrepreneurs to invest in and new energy vehicle charging piles? We can draw conclusions from the following two points.

Investment cost: The construction cost of DC fast charging piles generally ranges from hundreds to tens of millions, which is a considerable expense for investors. The input of AC charging pile is relatively small. The cost of a charging port is about 500~3500 yuan, but it can only be used when it is installed in a specific parking space·
Investment risks: There are still some shortcomings in the use of new energy vehicles, such as the problem of endurance, expensive battery replacement, inconvenient charging, generally low maintenance rate, and high insurance costs. Especially in cold cities, low temperature has a great impact on the endurance mileage of electric vehicles. These factors have always restricted the market development of pure electric vehicles, Therefore, the popularity of new energy vehicles in second and third tier cities is not high, and the investment in the installation of car charging piles is likely to cause an embarrassing situation of low utilization rate after the construction of the station.

Operation cost: The installation of DC fast charging requires the construction of an additional transformer, which involves complicated land use approval procedures. In addition, the technology and methods of large current protection are more complex, and the transformation, installation and operation costs are higher, so the car charging pile is not suitable for individual investors.
Human factors: The community has installed charging posts for new energy vehicles. What bothers new energy vehicle owners is not finding charging posts, but the problem of fuel vehicles occupying seats. Fuel vehicles "occupy" the charging parking space, and new energy owners can only stare and stomp. This is also a disadvantageous factor restricting the development of automotive charging piles.

According to the understanding of the investment cost and operating cost of the new energy charging pile, although the initial investment cost of the car charging pile is on the high side at present, there is still a certain development prospect for wave after wave of subsidies, and entrepreneurs are worth considering.
