Abstract
A battery remaining capacity measuring system for an electric motor vehicle in which current data and voltage data are sampled at an interval of 1 ms so that a plurality of current data and a plurality of voltage data are averaged at an interval of 100 ms, respectively, to obtain sets of average current data and average voltage data which in turn, are collected and plotted on a current-voltage-axis coordinate. In addition, the current-voltage-axis coordinate is divided into a plurality of zones, and when an in-zone quantity decision section decides that the number of sets of average current data and average voltage data exceeds a given value in all the zones, a correlation coefficient decision section decides a coefficient of correlation between current and voltage. When the coefficient of correlation shows a high correlation, an approximate straight line calculating section calculates an approximate straight line, while a remaining capacity calculating section calculates and displays a remaining capacity.
