  "textContent": "A power system includes: a first power circuit having a first battery; a second power circuit having a second battery, wherein a used voltage range of the second battery with respect to a closed circuit voltage overlaps with the first battery, and a static voltage of the second battery is lower than the first battery; a voltage converter, converting a voltage between the first and the second power circuit; a power converter, converting power between the first power circuit and a driving motor; a current sensor; a passing current control section, operating the voltage converter so that the passing current becomes a target current; and a failure determining section. The failure determining section determines the voltage converter fails in a case where the difference is greater than a threshold and the passing current flows from the side of the first power circuit to the side of the second power circuit.",
