The present invention provides a hybrid energy storage device. The hybrid energy storage device of the present invention comprises: a DC/DC converter which receives power from a power line and converts power into a driving voltage; a first energy storage unit which receives and stores a driving voltage from the DC/DC converter and outputs power during a propulsion operation; a second energy storage unit for storing regenerative energy generated from a motor; an inverter for driving the motor by receiving the power from the first energy storage unit and storing the regenerative energy generated from the motor in the second energy storage unit; a power converting device for converting the power of the second energy storage unit and supplying the converted power to the first energy storage unit; a first switching unit for forming a current path between the inverter and the second energy storage unit; a backflow blocking unit for blocking the regenerative energy from flowing to the first energy storage unit; and a control unit which controls the power converting device and the inverter during the propulsion operation to drive the motor, and controls the inverter and the first switching unit during regeneration to store the regenerative energy in the second energy storage unit. Therefore, energy efficiency can be increased by utilizing all the characteristics of the heterogeneous energy storage media.
