Summary: The inaccuracy of state-of-power and state-of-charge estimation in electric vehicle batteries leads to virtual loss of battery performance. An in-situ electrochemical impedance spectroscopy system is demonstrated to improve estimation accuracy. The impact of estimation errors on battery performance is quantified through simulations, and the accuracy of three common extraction techniques is examined. Experimental results show an improvement of approximately 8%-9% in SOP estimation accuracy compared to a baseline model.
