Abstract: A selector is to choose a target facility from the at least one facility based on a supplier position and a quantity of the energy suppliable. A distance calculator is to calculate a vehicle-facility distance from a current position to a facility position of a target energy supplier. A drivable range calculator is to calculate a drivable range of a vehicle based on a quantity of energy stored in an energy storage. A determining device is to determine whether or not to permit a power supplier to supply an electrical energy to an external device based on the vehicle-facility distance and the drivable range to control electricity supply from the power supplier to the external device.

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.
