Power supply apparatus, transport device including power supply apparatus, estimating method of estimating correlation information between charge rate and open-end voltage of electric storage section, and computer readable medium for estimating correlation information

Abstract

A power supply apparatus includes a first and second electric storage sections, a charge/discharge circuit performing charge/discharge between the first and second storage sections, and a control section controlling the charge/discharge circuit. The control section sets at least one of the first and second storage sections as a target storage section, acquires a target SOC and a target OCV which are respectively a charge rate and an open-end voltage of the target storage section, collects, by using charge transfer between the first and second storage sections, data including the target SOC and the target OCV in an order based on a collection rule determined by collected data and the target SOC, the collected data being an aggregation of the data which is collected, and estimates correlation information between an SOC and an OCV of the target storage section based on a plurality of the data.
