An input unit sets a charge time band or a discharge time band. A first firmware storage unit stores first firmware defining an operation content of a power supply device as a whole. An acquisition unit acquires second firmware which is firmware for an update, and a second firmware storage unit stores the second firmware. A control unit refers to the charge time band or the discharge time band and the like received from the input unit, and extracts a first time band in which the charge time band or the discharge time band is not set. The control unit preferentially sets a firmware update timing for the first time band. |
