PROBLEM TO BE SOLVED: To provide a power conversion system for performing intermittent output to a power storage device in which disconnection abnormality can be appropriately determined while structure is simplified.SOLUTION: A power conversion system includes: a DC/DC converter 10 which is connected to an electric load 8 and a sub-battery 7, converts voltage, and outputs electric power to the electric load 8 and the sub-battery 7; a voltage sensor 101 which detects output voltage of the sub-battery 7; a current sensor 102 which detects output current of the DC/DC converter 10; and a control section 11. The control section 11 controls the DC/DC converter 10, starts output when a detection value of the voltage sensor 101 is lower than voltage V1, and then stops output of the DC/DC converter 10 according to a charge state of the sub-battery 7. Furthermore, when a detection value of the current sensor 102 does not rise to an abnormality determination value Ie at the time of output execution, it is determined that disconnection abnormality occurs in a connection path L which connects the DC/DC converter 10 and the sub-battery 7 and the electric load 8. |
