Abstract

A power supply apparatus has a first electric storage section, a second electric storage section having an excellent energy density and a poor output density compared with the first storage section, and a control section that acquires first data and second data before and after each time of transferring charge between the first and storage sections, the first data being a combination of an SOC and an OCV of the first storage section, the second data being a combination of an SOC and an OCV of the second storage section, estimates a first correlation between the SOC and the OCV of the first storage section from an aggregation of the first data including reference data, and estimates a second correlation between the SOC and the OCV of the second storage section based on a comparison between a plurality of stored data and an aggregation of the second data.
