A battery system includes a battery panel (10A) which includes a battery pack (14) including a plurality of secondary battery cells (13), and a battery management unit (12) to monitor at least one of a voltage, a temperature and a degradation level of the secondary battery cell (13); and a DC/DC conversion device (20). The DC/DC conversion device (20) includes an interactive DC/DC converter (28) which converts power discharged from the battery pack (14) into a prescribed voltage to output converted power, and converts power supplied from outside into a prescribed voltage to output converted power; a control unit (26) which controls the interactive DC/DC converter (28); a communication unit (24) which communicates with the battery management unit (12) and the control unit (26); a control source unit (22) which converts the power supplied from the interactive DC/DC converter (28) or from outside into a prescribed voltage to supply converted power to the control unit (26), the communication unit (24), and the interactive DC/DC converter (28); and a battery (BT) connected to a power supply line of the control source unit (22) through a switch (SW). |
