A vehicle power supply device includes a battery (B1 and B2), a charging device (a charger (6), booster converters (12A and 12B) and inverters (14, 22)) capable of performing an internal charging operation for performing charging with an electric power generated by a motor generator (MG1 and MG2) and an external charging operation for performing charging by coupling to a power supply (8) outside the vehicle, and a control device (30) detecting a state of charge of the battery (B1 and B2) and controlling the charging device. The control device (30) executes a first estimation processing of estimating the state of charge in the internal charging operation and a second estimation processing of estimating the state of charge in the external charging operation. |
