Abstract: As the important link in the new energy car power system, the output stability and efficiency of the electro-driving system are crucial to the performance and energy consumption of the vehicle. In order to provide a reference for vehicle and motor control method and matching traction battery of the electro-driving system, the impact of DC voltage on performance of the electro-driving system was analyzed based on the mathematical and simulation model. A permanent magnet synchronous motor was used to conduct a bench test, and the validness of the theoretical analysis method was illustrated by experimental results.

Key words: voltage, electro-driving system, performance, impact analysis
