Abstract

The invention discloses a multi-gun direct current charging pile system of an electric automobile. According to the system, multiple electric automobiles can be charged at the same time, the charging powers of the multiple electric automobiles can be allocated dynamically in real time, and the using efficiency of a charging pile is improved. The system comprises n AC-DC power supply modules, m charging guns, a microprocessor and mxn contactors; wherein the n and m are integers more than or equal to 2; each AC-DC power supply module is connected with the microprocessor through the m contactors; after the charging guns are connected with the electric automobiles, the charging parameters of the electric automobiles are obtained through the microprocessor; and the microprocessor controls the breakover of the normally open contacts of corresponding contactors, thus charging the electric automobiles through the electric automobiles connected with the contactors.

Description

technical field [0001] The invention relates to the technical fields of new energy electric vehicles and power electronics, and in particular to a multi-tip DC charging pile system for electric vehicles and a method for using the system. Background technique [0002] With the advancement of technology and the development of science and technology, as well as the increasingly serious environmental pollution, new energy vehicles are more and more accepted by the public due to their energy saving and environmental protection. The charging problem of electric vehicles is also more and more paid attention to by people. Many charging piles have been built in many places in China to charge electric vehicles, which has played a very good role in the promotion of electric vehicles. [0003] The DC charging piles used for charging electric vehicles are commonly known as "fast charging". The current DC charging piles in the industry are classified by the number of built-in charging gu...
