Abstract: Range extended electric vehicle can effectively play the advantages of pure electric vehicles, it solves the problem of short range. The range extended electric vehicle is the research object, the power transmission scheme of the range extended electric vehicle is designed. This design calculates the motor, internal combustion engine, battery and other main power unit parameters, the design of energy recovery and control strategy are studied, new european driving cycle and FTP-75 operating conditions are simulated, the simulation results show that the design of electric vehicles, It gives full play to the characteristics of electric vehicles, such as zero emissions, less petrochemical energy, The design parameters meet the road driving conditions, the design energy efficiency is excellent and meets the requirements of electric vehicles driving range.

Key words: Range extended electric vehicle; Power system; Parameter matching; Simulation analysis
