A system for evaluating a battery assembly includes an acquisition module configured to acquire parameters related to a battery assembly, and an evaluation module configured to acquire an equivalent circuit model representing a battery cell of the battery assembly and run the equivalent circuit model to simulate charging and discharging. The equivalent circuit model includes an open circuit voltage (OCV), an internal resistance, and three resistor-capacitor (R-C) pairs, each R-C pair being a parallel R-C network connected in series to the internal resistance, each R-C pair having a time constant selected from a respective time constant range, each respective time constant range selected based on estimations of physical phenomena associated with operation of the battery cell.
