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

An estimating method of estimating correlation information between an SOC and an OCV which are respectively a charge rate and an open-end voltage of a power supply apparatus, the power supply apparatus including:

• a first electric storage section;
• a second electric storage section;
• and
• a charge/discharge circuit which performs charge/discharge between the first electric storage section and the second electric storage section, wherein
• the estimating method comprises:
• setting at least one of the first electric storage section and the second electric storage section as a target electric storage section,
• acquiring a target SOC, which is an SOC of the target electric storage section, and a target OCV, which is an OCV of the target electric storage section,
• collecting, by using charge transfer between the first electric storage section and the second electric storage section, 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
• estimating correlation information between an SOC and an OCV of the target electric storage section based on a plurality of the data.
