Abstract
A hybrid vehicle includes an engine, a motor generator, a battery, and an ECU (Electronic Control Unit). The ECU is configured to calculate an evaluation value indicating a degree of progress of deterioration of the battery, the deterioration being caused by an imbalance in a salt concentration in the battery, and is configured to execute a high-rate deterioration suppressing control that raises a target SOC (State of Charge) of the battery when the battery is evaluated to be deteriorated in accordance with the evaluation value. The ECU is configured to also raise the target SOC when an actual SOC is increased due to an electric power generation by the motor generator during the execution of the high-rate deterioration suppressing control. The raised target SOC is lower than the increased actual SOC.
