A device and a method for storing hybrid energy are provided. A hybrid energy storage device according to one embodiment of the present invention comprises: a first bidirectional switch which is provided between a UC and a bidirectional DC/DC converter and provides a bidirectional energy flow path between the UC and a DC link capacitor; and a second bidirectional switch which is provided between a battery and the bidirectional DC/DC converter and provides a bidirectional energy flow path between the battery and the DC link capacitor, wherein one end of the bidirectional DC/DC converter is connected to the DC link capacitor and the other end thereof is connected to the UC and the battery. Accordingly, since an energy flow between a plurality of various energy storages is enabled with a single bidirectional DC/DC converter, a separate bidirectional DC/DC converter for each energy storage is unnecessary. |
