In relation to an electric energy storage device or others, a configuration of efficient power feeding means to a control circuit is achieved. A storage device of a present embodiment includes a storage battery; an input/output terminal connectable to a power supply; a power converting device between the storage battery and the terminal; a control unit including a control circuit to controls charge/discharge of the storage battery; a first DC/DC converter connected to a first node between the storage battery and the power converting device and which outputs a first voltage; a second DC/DC converter connected to a second node inside the power converting device and which outputs a second voltage; a first diode connected between the first DC/DC converter and the control circuit; and a second diode connected between the second DC/DC converter and the control circuit. The first voltage and the second voltage are different from each other. |
