A remaining-battery-capacity estimation method provides measurement of battery discharge exploited to allow the true value to be estimated in a short time. The estimation method estimates the remaining capacity of a battery that is rechargeable and, an explained variable for estimating remaining capacity of a battery is defined. A plurality of explanatory variables that are of high importance as elements and are used for the estimation of remaining capacity and that have linearity are extracted. A relational formula represents the relationship between the explained variable and the explanatory variables and is derived as a regression formula; the regression formula is utilized to carry out a timewise lapse estimate for at least one of the battery discharge voltage and the battery discharge current, to estimate the remaining battery capacity.
