We present an equivalent-circuit-based battery model, capable of simulating charge and discharge behavior of lithium-ion batteries (LiB). The model, although simple in concept, can simulate complex discharge behavior with high fidelity, as validated

Cells were life-cycled cells using profiles with a 3, 6, or 9% change in state of charge (ΔSOC) at 40, 50, 60, and 70 °C. From the voltage response of the cells to the life-cycle profile at each temperature, we separated the overall impedance rise
