As a representative of green transportation, new energy vehicles have many advantages of energy conservation and environmental protection compared with traditional fuel vehicles. And the economic and environmental costs are also low. New energy vehicles are widely accepted by people. In the era of rapid development of new energy vehicles, charging piles have become an important part of new energy vehicles. In recent years, China's new energy vehicles have achieved rapid development. But there are also some problems in this process. The development of charging piles is lagging behind, which seriously restricts the development of new energy vehicles. Therefore, it is of great significance to study the selection and installation of charging piles for new energy vehicles.
At present, green environmental protection has become the mainstream of the world. Countries around the world have promoted new energy vehicles. The automobile industry has entered the stage of new energy. In China, the development of new energy vehicles has become a national strategy. On the one hand, new energy vehicles are very important to the construction of our country. Automobile power has important guiding significance. On the other hand, the development of new energy vehicles is a measure to solve the current environmental pollution problem. The "Made in China 2025 Automobile Plan" also proposes energy-saving and new energy vehicles, and clearly puts forward the development goal of reaching one-sixth of the domestic market share of new energy vehicles by 2025. The development of new energy vehicle charging piles is lagging behind, which has a great impact on the promotion of new energy vehicles. Therefore, the current construction of new energy vehicle charging piles is conducive to promoting the development of new energy vehicles in the country. At present, the charging of new energy vehicles is mainly divided into two ways: vehicle charging and battery replacement. Vehicle charging is divided into conductive charging and inductive charging according to the charging equipment and the settings accepted by the car. There is also a battery swap mode to replace the battery. Mainly through conduction charging, including AC charging and DC charging. The direction and magnitude of the DC current is constant, whereas the AC current changes differently over time. Different charging stations use different charging times. Charging stations are also used in different locations. In this case, the charging pile uses direct current for a long time, and the charging efficiency is low. It usually takes about ten hours. Due to the dispersion of charging stations, AC charging is very difficult and difficult to maintain. 。
