    Abstract: A power calculation apparatus includes a microprocessor and a memory. The microprocessor is configured to perform: acquiring a power amount information regarding amounts of power input to and output from a plurality of vehicles, the amounts of power being detected by a plurality of measuring instruments provided in the plurality of vehicles or interposed between a power grid and the plurality of vehicles; classifying the plurality of measuring instruments based on errors possessed by the plurality of measuring instruments to set a plurality of groups; and calculating a total power input and output in each of the groups, based on the power amount information. The setting the plurality of groups includes setting the plurality of groups such that a mean value of errors of amounts of power in the groups is a predetermined value or less.

    Abstract: An output current of a DC/DC converter which serves as a step-down device for charging the low-voltage electric storage device is detected. Based on the detected output current and the efficiency of the DC/DC converter, the electric power consumed by an auxiliary equipment load that is connected parallel to the low-voltage electric storage device is controlled to make the efficiency of the DC/DC converter equal to or greater than a prescribed efficiency, so that the low-voltage electric storage device can be charged from a high-voltage electric storage device or an external power supply.
