We propose a novel time scale-based observer to estimate the state-of-charge (SoC) of a Lithium-ion battery. The design of the observer promises eventual hardware instantiations that require less power to operate than standard observer designs, while still increasing the accuracy of SoC estimation relative to Coulomb counting methods.1
