Generally believed that domestic and foreign auto manufacturers of hybrid electric vehicles is the most promising new development and promotion of transport. The original motivation for hybrid electric vehicles, electric motors, energy storage devices (batteries) together, a good match between them and optimize the control unit can take advantage of the natural advantages of cars and electric vehicles, to avoid their shortcomings, is the The most significant practical development of low emissions and low fuel consumption car, hybrid electric vehicles to carry out the research has very important practical significance, and hybrid vehicles are very bright prospects.This article analyzes the basic types of HEV and their characters. The present condition of HEV in the home and outside and its trends are presented. The proposal to
