The present invention relates to a power conversion device having a battery heating function. The power conversion device includes: a battery; a bidirectional converter including a first circuit portion coupled between the battery and a DC link, a relay between a second node and a first node to which the first circuit portion and the battery are coupled, and second and third circuit portions which are coupled to each other between the second node and the DC link; and a controller configured to heat the battery by controlling the bidirectional converter in a battery heating mode. According to the present invention, the power conversion device can perform the battery heating function without a separate heating device. |
