Assessment of power consumption control strategy for battery management system using hardware-in-the-loop simulation

Abstract

Based on a self-designed battery management system (BMS), four different working modes with different power consumption levels are set according to driving conditions of hybrid electric vehicle. A power consumption control strategy including the communication rules between vehicle management system (VMS) and battery management system (BMS) is created to make BMS switch reasonably and reliably among different working modes so as to realize as low power consumption as possible. Especially, to validate the feasibility, reliability and necessity of the strategy, hardware in the loop (HIL) simulation is introduced. Also some abnormal events are simulated or fabricated during HIL simulation process to test the performance of the control strategy. After the HIL simulation, the power consumption and whole work consumption integral of BMS is evaluated and assessed.
