Abstract: By comparing the whole vehicle architecture of pure electric vehicle and extended range electric vehicle (EREV), the feasibility of transforming pure electric vehicle into EREV mule car is analyzed. It is lower cost source and shorter updated time when using existing models to EREV mule car. Taking into account the differences between the two vehicle models, determine the development plan for the mule cart of this model. Based on a EREV mule car, this paper expounds the main reform contents such as the general layout analysis of the prototype car, the design of the compound power system, the compatibility of the prototype car controller and the software development, and the development of the body-in-white etc. From the body strength control method, body precision control method, vehicle airtightness control method, suspension system modification method, exterior decoration parts modification method, instrument table tube beam modification method, the application of innovative methods is described in detail.
