A battery pack includes a plurality of modules connected in series to one another. Each of the plurality of modules includes a plurality of cells connected in parallel to one another. If a first condition and a second condition are satisfied, an ECU diagnoses an abnormality in which a current path of a cell included in any module breaks. The first condition is a condition that the voltage difference between the maximum voltage and the minimum voltage among a plurality of voltage values is less than a reference value before execution of plug-in charging control, each of the plurality of voltage values being detected by a corresponding one of a plurality of voltage sensors. The second condition is a condition that the voltage difference between the maximum voltage and a voltage is more than or equal to the reference value after execution of the plug-in charging control.

In the case that there is the charge record of the charger at the system startup time, the motor travel priority mode is set as the travel mode when the accumulated charge ration SOC is more than or equal to the threshold value Sev, and the hybrid travel priority mode is set as the travel mode when the accumulated charge ratio SOC is less than the threshold value Sev. In the case that there is no charge record of the charger, the travel mode is set in the same way as the case that there is the charge record when the hybrid travel shift flag Fhv is equal to value 0, and the hybrid travel priority mode is set as the travel mode when the hybrid travel shift flag Fhv is equal to value 1.
