ABSTRACT:
A method and a device for determining the battery discharge characteristics and estimating the remaining battery capacity easily by a simple mechanism even if time elapses. A discharge characteristics calculation section reads voltage, current, and temperature from a voltage sensor, a current sensor, and a temperature sensor, respectively, and determines the approximated discharge characteristics at a given time based on a position relationship of the discharge characteristics curved surface function V=a.multidot.log(H.sub.0 -H)+b.multidot.H+c to voltage-temperature-duration of discharge axes. A duration of discharge characteristics calculation section determines the duration of discharge from a fully charged state to the present based on the approximated discharge characteristics. A remaining capacity calculation section determines the remaining capacity based on the approximated discharge characteristics.
