The invention provides an external power source device and a power supply system. The external power source device comprises a power supply processing circuit, a first external interface circuit and a second external interface circuit, wherein the first external interface circuit and the second external interface circuit are connected with the power supply processing circuit. The first external interface circuit is used for providing a connection interface for a power supply circuit for an external library, and the second external interface circuit is used for providing a connection interface for a power bus for an external motor train unit. The power supply processing circuit is used for providing a power source of the power supply circuit for the external library for various power supply loads needed by the motor train unit through the power bus. The mounting position of the external power source device can be flexibly arranged, and the number of the devices can be set according to needs.
