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.

Method and apparatus for determining the state-of-charge of a battery

A method for operating a battery system having multiple battery packs. The method includes decoupling the output of a discharged battery pack from the vehicle load, reducing the voltage between an output of a charged battery pack and the vehicle load prior to coupling the output of the charged battery pack to the vehicle load.
