Abstract
A method and apparatus for determining the state-of-charge of a battery. In response to detecting that the battery is in a rest state, a pre-conditioning current is drawn from the battery to affect a correlation between the state-of-charge of the battery and an open-circuit voltage of the battery. Thereafter, the open-circuit voltage of the battery is measured, and used to determine the state-of-charge.
