混合动力汽车中的电力驱动过程简析(简报)

    Analysis of electric drive process of hybrid electric vehicles

    • 摘要: 该文在概略说明了为什么要发展混合动力汽车并介绍了混合动力汽车的3种主要类型后,对其电力驱动系统的组成和运行状态进行了分析,包括启动、轻载和满载运行以及刹车制动等工况。重点分析了电力驱动系统中,随着给定电压的变化(由高到低),电动机从电动状态进入再生制动状态的详尽物理过程,指出在这一过程中电机电感所起的关键作用,可加深对电动机工作过程的理解。

       

      Abstract: The main purpose of the article is to help to get a better understanding of the working process of an electric motor in a hybrid electric vehicle. Followed the summary on the benefits of developing hybrid electric vehicles and the brief introduction to three major types of hybrid electric vehicles, this article analyzed the electric drive system and the working conditions, including the condition of starting, partial loading, full loading and braking. The analysis focused on, along with the change of given voltages (from high to low) in an electric drive system, the exhaustive physics process of the electric motor switched from driving condition to regenerative braking, and the paper pointed out the key function of motor inductance played in the process.
