An effective online PMS is critical for the future electrified vehicles as it has direct impacts on fuel economy, greenhouse gasses (GHG) emission, as well as the durability of power-train components. In this paper, we considered a PMS developed based on the concept of model predictive control (MPC) which formulates the control design as an optimization problem that is solved based on forecasted system behaviors over a limited prediction horizon to obtain the optimal control actions for the current time instant. The main contribution of this paper is that we take a systematic approach to examine the link between model fidelity and controller performance for the case of a hybrid energy storage system in a light-duty hybrid electric vehicle. A sensitivity analysis approach is developed and presented in this paper along with preliminary simulation results to demonstrate the impact of battery model fidelity on the performance of the proposed PMS.
