摘要
吉利帝豪EV450电机控制器控制着动力电池组到电机之间能量的传输,同时采集电机位置信号和三相电流检测信号,精确地控制驱动电机运行。电机控制器将动力电池中高压直流电逆变为交流电以驱动电机,同时具备能量回收功能,车辆制动或滑行阶段,将车轮旋转的动能转换为电能给动力电池充电,电机作为发电机应用。本文详细介绍了吉利汽车帝豪EV450的电驱动系统,从结构组成、工作模式、工作原理及故障检修等方面进行系统阐述。
The Geely Emgrand EV450 motor controller controls the energy transmission from the power battery pack to the motor,and collects the motor position signal and the three-phase current detection signal at the same time to accurately control the operation of the drive motor.The motor controller inverts the high-voltage DC power in the power battery to AC power to drive the motor.It also has an energy recovery function.The kinetic energy of the wheel rotation is converted into electrical energy to charge the power battery during the braking or coasting phase of the vehicle.The motor is used as a generator.This article introduces the electric drive system of Geely Auto’s Emgrand EV450 in detail,and systematically explains the structure,working mode,working principle,and troubleshooting.
