An on-vehicle power supply device includes: batteries (B1, B2); charge devices (a charger (6), boosting converters (12A, 12B), and inverters (14, 22)) which are configured to perform an internal charge operation for charge by power generated by motor generators (MG1, MG2) and an external charge operation for performing charge by connection to a power source (8) outside the vehicle; and a control device (30) which detects the charge state of the batteries (B1, B2) and controls the charge devices. The control device (30) executes a first estimation process for estimating the charge state upon the internal charge operation and a second estimation process for estimating the charge state upon the external charge operation. |
