The objective of the present invention is to improve the reliability of a charging device while maintaining a high battery charging efficiency. When a battery voltage Vbatt is less than VbattL, a situation in which surplus power Pdump is generated, a voltage command value sent to a first converter 107 is controlled in such a way that a power output P1out output from the first converter 107 changes from the state indicated by the dotted line to the state indicated by the solid line. By this means, the power output P1out output by the first converter 107 tracks a power output P2out output by a second converter 108. As a result, a rise in a link voltage Vlink can be suppressed in such a way that the link voltage Vlink changes from the state indicated by the dotted line to the state indicated by the solid line. |
