When an abnormality of one of current sensors (20) corresponding to a plurality of phases is detected during charging, a control device (16) of a vehicle power source device (10) configured to execute a ripple restraining control to continue the charging while controlling switching elements (Q1, Q2) in remaining normal phases of the plurality of phases such that a ripple current (Ir) to be generated by operation of the switching elements (Q1, Q2) in the normal phases does not exceed a ripple current threshold (THr). The ripple current threshold (THr) corresponds to an allowable value of the ripple current (Ir) to be generated by operation of the switching elements (Q1, Q2) in the plurality of phases when there is no abnormality in any of the current sensors (20) corresponding to the plurality of phases.
