Real-Time Simulation of a Complete Electric Vehicle Based on NI VeriStand Integration Platform

Abstract

The paper presents a virtual test bench for the evaluation of a complete electric vehicle in Real-time based on the new configuration-based software environment NI VeriStand, using the scale vehicle dynamic testing. LMS Amesim software is used for testing and verification of a virtual electric vehicle model on a route where a New European driving cycle (NEDC) must be achieved. The model is uploaded into the real-time processor of the NI PXIe-8135 but first has to be converted into a DLL file (Dynamic-link library). Two FPGA’s will be used in order to model the machine, a Permanent Magnet Synchronous Machine (PMSM) and the control of the machine with Field Oriented Control. The connection between the FPGA’s and the PXI is done by digital and analog I/Os, using the connection boxes. The equipment’s and the software used to programmed them are from National Instruments. The link between the Amesim model and the LabView FPGA, that is used to programmed the FPGA’s, was made in NI Veristand.
