Claim 0:
1. A device (42) for controlling electric power of a hybrid vehicle, the power control device (42) comprising:
an internal combustion engine (11);
a motor (21) that can be coupled to a drive wheel (18) of the vehicle;
a generator (22) that can be coupled to the internal combustion engine (11);
a first secondary battery (31) that is 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 is connected to the first secondary battery (31) and the second secondary battery (32), 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), wherein
the power control device (42) of the hybrid vehicle is configured to supply electric power that is generated by the generator (22) to the first secondary battery (31) via the second secondary battery (32) and the converter (33) when a charging rate (SOC2) of the second secondary battery (32) is equal to or higher than a specified value or when an increase rate of the charging rate (SOC2) of the second secondary battery (32) is equal to or higher than a specified value.
