Description

technical field [0001] The invention relates to the technical field of charging electric vehicles, in particular to an intelligent and efficient charging device for electric vehicles. Background technique [0002] With the increasing shortage of traditional energy and the seriousness of environmental pollution, the development of clean energy is the long-term direction of the future. In order to solve the air pollution problem of urban vehicles, electric vehicles powered by rechargeable batteries have been greatly developed. Due to the limited storage energy of batteries at present, the application of electric vehicles is seriously restricted. Therefore, how to charge electric vehicles efficiently and quickly, become a very urgent and important issue. [0003] At present, my country has introduced policies to support and guide the healthy development of the electric vehicle industry, and formulated technical standards for electric vehicles, which provides a good opportunity...
