Abstract

The present disclosure includes systems and methods for state of charge estimation. In one embodiment, the present disclosure includes a method comprising receiving a voltage corresponding to a state of charge of a battery, converting the voltage to an estimated state of charge using different algorithms across different ranges. In another embodiment, an offset state of charge is applied to a first state of charge to produce an estimated state of charge.
