Abstract

As one of the core technologies of new energy vehicles, the electric drive system is crucial for improving energy efficiency and vehicle performance. The efficiency optimization of the electric drive system can not only effectively extend the driving range but also reduce energy consumption, promoting the development of green transportation. This paper proposes a multi-objective control-based method, aiming to optimize the performance of the electric drive system in terms of power output, energy recovery, thermal management, etc., simultaneously. By analyzing the multi-dimensional operation characteristics of the system, control strategies adapted to different working conditions are designed to achieve more efficient energy utilization. The optimized electric drive system can effectively improve the overall efficiency in various driving environments, showing strong practical application potential.
