A battery monitoring system for a battery pack of an electric vehicle. The battery monitoring system may include a virtual cell model configured for generating a definitive output based on a current through the battery pack and a definitive equivalent circuit model (ECM) for a virtual cell and a physical cell model configured for generating an indefinitive output based on the current and an indefinitive ECM for the battery pack. The battery monitoring system may include an SOC transformation module configured for generating a battery SOC for the battery pack based at least in part on the definitive and indefinitive outputs.
