为了充分利用电动汽车(EV)储能系统的价值，迫切需要 整体电机驱动效率保持在较高水平。变速箱是任何 电动汽车或系列插电式混合动力(PHEV)传动系统。在电动汽车/混合动力汽车中，可以连接牵引 电机直接连接到传动轴，因为电机的扭矩-速度特性表现出平稳过渡。 (1-速度安排)。然而，这是一个特别昂贵的过程，并且描述了相当低的传动系统 效率。考虑到这一不足，该项目的主要目标之一是准确地模拟典型的 EV/系列PHEV传动系，使用现有的变速器拓扑(单速驱动)。开发的模型将 然后进行模拟，以针对特定的功率需求执行详细的驾驶循环负载研究。然后，一个 将使用以下收集的数据进行全面的参数分析和性能比较 InMotive的InGear®专利技术适用于电动汽车动力传动系统。该项目还将承担 永磁同步电机关键性能参数的建模、仿真与分析 (PMSM)驱动器，与建模的1速驱动系统配合使用。永磁同步电机1速变速器 本项目中研究的模型将很好地定位项目，为后续的实际验证和 发展阶段。

In order to utilize the full value of an electric vehicle (EV) electric energy storage system, it is imperative that the overall motor drive efficiency be maintained at an elevated level. The transmission is an integral part of any EV or series plug-in hybrid electric (PHEV) drivetrain. In EVs/PHEVs, it is possible to connect the traction motor directly to the drive shaft, since the motor torque-speed characteristics exhibit smooth transitions (1-speed arrangement). However, this is a particularly costly process, and depicts rather low drivetrain efficiency. Keeping this deficiency in mind, one of the major goals of this project is to accurately model typical EV/Series PHEV drivetrains, using existing transmission topologies (1-speed drive). The developed model will then be simulated, to perform detailed drive cycle load studies for a particular power demand. Then, a comprehensive parametric analysis and performance comparison will be conducted, using data collected from the inMotive's patented inGear® technology for an EV drivetrain. The project will also undertake the modeling, simulation, and analysis of key performance parameters for permanent magnet synchronous motor (PMSM) drives, working in conjunction with the modeled 1-speed drive system. The PMSM 1-speed drive models studied in this project will position the project nicely for the subsequent practical validation and development phase.
