Abstract

The invention relates to the field of electric cars and new energy sources and discloses an energy storage DC rapid charging pile system, comprising an energy storage device, wherein one end of the energy storage device receives alternating current from a power supply device with a relatively low input power and outputs alternating current with relatively high output power through a charging interface after storing the electric energy for a period of time. The invention further discloses an application method of the energy storage DC rapid charging pile system. The energy storage DC rapid charging pile system and the application method thereof have the advantages that the problems that a power grid needs to be reformed and grid fluctuation can be caused easily when electric power is taken from a civil power supply line through the charging interface can be solved; stable and high-power discharging to the charging pile can be realized; the charging efficiency is improved; the interference with power supply to the charging pile due to power grid reasons can be reduced; the problem about direct connection with the civil power supply line can be solved.

Description

technical field

[0001] The invention relates to the field of electric vehicles and new energy applications, in particular to an energy storage DC fast charging pile system and a method for applying the charging pile system, which have the characteristics of fast charging, convenient installation and good application prospects. Background technique

[0002] With the rapid development of the automobile industry, the petrochemical energy crisis and automobile exhaust pollution are becoming increasingly serious. Energy-saving and environmentally friendly electric vehicles are of great significance to the sustainable development of our country. The use of electric vehicles can replace traditional petrochemical energy with electric energy on the one hand, effectively reducing dependence on petrochemical energy; on the other hand, it can reduce vehicle exhaust emissions and alleviate urban smog and other environmental pollution issues. In recent years, the development of domestic ...
