Abstract
Challenges and opportunities of integrating electric vehicles (EV) with an electric grid have been of great interest for the past few years. In order to integrate with an electric grid, a battery model of the EV should have adequate control mechanisms. In this paper, we consider a nonlinear model of a 2-RC battery. For optimal tracking of a reference terminal voltage, a closed-loop optimal control strategy is obtained by using the State-Dependent Riccati Equation (SDRE) technique with performance index to minimize the quadratic error between the reference and actual trajectories. Simulation results with a lithium-ion (li-ion) battery shows good tracking performance.
