Abstract

A battery condition detecting method is provided which includes the steps of setting a current required during standard discharge of a battery as a set current, detecting a discharge current and a voltage of the battery, determining a battery voltage when the battery discharges the set current based on the discharge current and the voltage of die battery, and projecting an actual voltage of the battery based on the battery voltage determined.
