Abstract
In accordance with aspects of the present invention, a method of providing a fuel gauge is provided. The method includes measuring a battery current through and a battery voltage across a battery; determining an equivalent resistance from the current and the voltage using a multiplier K; determining an open circuit voltage based, in part, on the equivalent resistance; determining a state-of-charge based on the open circuit voltage; and adjusting the multiplier K based on the current and the state-of-charge.
