采用模块化设计方法研制了一套大功率、宽转速的电动车动力系统测试平台，可针对不同类型的电动汽车驱动电机、控制器和动力总成等进行单部件及系统测试，可适应不同通信协议的电机CAN通信配置，且可进行自定义路况试验（包含电惯量模拟）。主要从测试平台总体设计原理，测试平台测控系统设计和试验结果分析3个方面进行分析。结果表明，该测试平台能够满足不同类型的宽转速范围的电机及控制器的测试需求。

A set of high-power and wide-speed-range test platform for electric vehicle power system is developed by using modular design method. It can perform single component and system testing for different types of electric vehicle drive motors, controllers, and powertrains. It can adapt to the CAN configuration of different communication protocols, and can carry out custom road tests (including electric inertia simulation). The overall design principle of the test platform, the design of the measurement and control system of the test platform, and the analysis of the test results are given detailedly. The results show that the test platform can meet the test requirements of different types of motors and controllers with wide speed range.
