POWER CONTROL DEVICE AND POWER CONTROL METHOD FOR HYBRID VEHICLE

The present invention provides a power control device for a hybrid vehicle that can allow power generation by a generator connected to a low-voltage battery regardless of a charging rate of the low-voltage battery. The hybrid vehicle includes: a motor (21) that can be coupled to a drive wheel (18) of the vehicle; a generator (22) that can be coupled to an internal combustion engine (11); a first secondary battery (21) connected to the motor (21); a second secondary battery (32) that is connected to the generator (22), and a voltage of which is lower than that of the first secondary battery (31) ; and a converter (33) that steps up a DC voltage received from the second secondary battery (32) and can output the stepped-up DC voltage to the first secondary battery (31).
