Abstract: According to the range extension system scheme design and the matching principle of the range extender. In this paper, the selection of the range extender was analyzed, and the simulation model was established with the help of MATLAB\Simulink platform. Based on the C-WTVC working condition, the performance simulation test of the extender hybrid electric vehicle was completed to determine the fuel economy of the engine and verify the rationality of the range extender selection.

Key words: Range-extender; Performance simulation; Fuel economy
