Abstract
A life prediction apparatus for an electrical storage device, which has a life predictor, includes: an operation controller for life prediction that controls operation of the electrical storage device; a data collector that collects measurement data with respect to a plurality of operation conditions and calculates and successively accumulates evaluation characteristics; a data analyzer that creates a regression formula representing a relationship between the evaluation characteristic and an operation time by curve fitting, with an appropriate approximation function, the accumulated evaluation characteristic data; and a life prediction formula creator that creates a life prediction formula for calculating a predicted value of the evaluation characteristic under random operation conditions on the basis of the regression formula.
