A DC power supply device sharing a protection circuit module (PCM) according to the present invention is capable of supplying power in an embedded battery to other devices. The DC power supply device sharing a PCM comprises: a power relay unit capable of selectively connecting a separate external battery that is connectable to the embedded battery; a protective circuit module for protecting internal circuit devices of the power supply device; a console unit for allowing a user to select one among the embedded battery and the external battery as a power source for supplying power to the other devices, or allowing the user to select an output voltage to output to the other devices; an external battery connector to be connected to the external battery through a cable; a cell balancing connector for cell balancing checking of the external battery; and a selecting circuit unit for changing configuration of a circuit inside the power supply device according to settings or selections by the console unit. |
