Research on the Real Time Simulation of HEV Motor Pre-Charge Using an Embedded Control System

Power battery in the HEV normally has a high capacity. Therefore during the start-up procedure of HEV motor, pre-charge phase is essential in order to reduce the impact of high current. In this paper, we build a HEV motor pre-charge model then deploy it on cRIO embedded control system to simulate the whole process with high real time. Finally the paper tests some typical fault conditions which demonstrate great benefits.
