The present invention relates to a power supply device, method, and program capable of ensuring billing processing occurs after charging. When a vehicle ID registered beforehand in an external storage device (13) and a vehicle ID obtained by a reader/writer (34) match, a control unit (31) requests that information determining the amount of power to be charged is input by the operation of a display unit (39) comprising a touch panel. Once the information determining the amount of power to be charged is input, the control unit (31) controls a billing unit (31c), causes the amount of power to be calculated, and causes a billing server (14) to execute billing of the corresponding amount. Then, the control unit (31) controls a communications unit (32), turns ON a switching switch (37), and causes a battery (52) in an electric vehicle (12) to be charged using power superimposed by a low-pass filter (36). This technology can be applied to a power supply system. |
