Implementation of Electric Vehicle Hardware-in-the-Loop Test Platform

Abstract

This paper presents a finite element model-based real-time simulation system for the permanent magnet synchronous motor (PMSM) driving system, which, in combination with the vehicle kinetic model, forms a complete electric vehicle (EV) hardware-in -theloop (HIL) simulation and test platform. The software JMAG is used to establish the PMSM finite element model, and the platform of field-programmable gate array (FPGA) is adopted to construct the PMSM real-time simulation model. The finite element model is also retrieved to coordinate with the vehicle kinetic model in order to facilitate the testing and development of the controller of the EV, the matching of the driving system, the kinetics control algorithms, etc. Through comparing the real-time simulation of the motor driving system with the experimental results of the test bench, as well as analyzing the HIL simulation results of the entire vehicle model, this paper verifies the accuracy and effectiveness of this HIL simulation and test platform.
