Abstract

The power source apparatus enables each battery pack to be charged with power supplied from an external charging power supply, and allows power stored in each battery pack to be output externally. Each battery pack is provided with battery pack fault output terminals to send battery pack error signals to other battery packs or to the protection unit when a malfunction occurs. The protection unit is provided with protection unit input-output terminals to connect with battery pack fault output terminals, and a protection circuit capable of cutting-off battery pack current. When a battery pack malfunction occurs, a battery pack error signal is output from the battery pack fault output terminals to the protection unit input-output terminals. When the protection unit detects a battery pack error signal, the protection circuit cuts-off current.
