Title: POWER SUPPLY DEVICE
Abstract:
A power supply device is provided with a disconnection means (AND element) for forcibly disconnecting a battery module from a series connection regardless of a gate signal. The power supply device forcibly disconnects partial battery modules from the series connection by the disconnection means (AND element) during powering by a power supply output, thereby performing control so that the accumulated discharge current amounts thereof per unit time become smaller than those of the other battery modules.
