Abstract
An ECU switches a control mode to an HV mode when an SOC decreases to a lower limit during an EV mode. The ECU calculates an evaluation value ΣD of high-rate deterioration indicating a deterioration component of a secondary battery due to non-uniformity in salt concentration in a battery. The ECU executes high-rate deterioration inhibiting control when the HV mode is currently selected and when the battery is evaluated as deteriorating based on the evaluation value ΣD, the high-rate deterioration inhibiting control being control for increasing the SOC by making a control target of the SOC higher than the lower limit of the SOC. On the other hand, the ECU does not execute the high-rate deterioration inhibiting control when the EV mode is currently selected.
