A power supply device includes a combination of one power supply module of a plurality of power supply modules having different power supply performances and one controller of a plurality of controllers having different functions, which are selectively combined. Each of the plurality of power supply modules includes a power supply module side connection portion common to the plurality of power supply modules, and each of the plurality of controllers includes a controller side connection portion common to the plurality of controllers and connectable to the power supply module side connection portion, to allow the one power supply module and the one controller are selectively combined.

Power supply device and method for providing power supply device

An auxiliary power supply device includes an auxiliary power supply; and an auxiliary power supply control unit configured to switch a mode of the auxiliary power supply to an output mode or a non-output mode when electric power is output from a main power supply to a drive motor. The auxiliary power supply control unit is configured to switch the mode to the non-output mode when a required power value required by the drive motor is equal to or smaller than a predetermined power value and to switch the mode to the output mode when the required power value is larger than the predetermined power value, the predetermined power value being set to a value smaller than outputtable electric power that is electric power outputtable from the main power supply.
