A hybrid vehicle (1) includes a battery (10-1), a motor-generator (32-2) operable to produce driving force using electric power of the battery (10-1), a charger (28) operable to charge the battery (10-1) by means of an external power supply, and an ECU (40). The ECU (40) stores a given parameter used in battery model expressions. The parameter varies according to the status of the battery (10-1). During running of.the hybrid vehicle (1) and during charging of the battery (10-1) with the external power supply, the ECU (40) collects data related to the status of the battery (10-1), corrects the parameter based on the data, and calculates a value of charging rate (SOC) of the battery (10-1). The ECU (40) controls charge/discharge of the battery (10-1), based on the calculated SOC value. |
