Abstract
There is provided a power supply device including a plurality of battery modules, the battery modules being connected in series with one another according to a gate driving signal from a controller, the power supply device transmitting the gate driving signal from upstream of the series connection toward downstream of the series connection after the gate driving signal is delayed at delay circuits included in the respective battery modules, and returning the gate driving signal to the controller from a most downstream battery module, wherein the power supply device performs malfunction determination of the delay circuits based on a time difference from a transmission time of a signal from the controller to a reception time of the signal.
