Abstract
A hybrid vehicle includes an engine, a motor generator, a main battery, a DC-DC converter, a sub-battery, a starter, and an electronic control unit. The DC-DC converter is a bidirectional converter configured to convert a voltage of electric power from the sub-battery and output the electric power to the motor generator. The electronic control unit is configured to control the DC-DC converter such that the sub-battery outputs electric power to the motor generator when a first available electrical energy of the main battery is smaller than a required electrical energy at the time when the engine is started with the use of the motor generator.
