Abstract
A reduction in the discharge voltage, caused due to a memory effect of a battery, is checked during a discharge operation. An initial discharge characteristic curve, representing an initial relationship between the discharge voltage and the discharge amount of the battery, is parallel shifted so as to coincide with the actual discharge condition, thereby obtaining an estimated discharge characteristic curve in a non-discharged region.
