Claim 4:
5. A method for controlling electric power of a hybrid vehicle including:
an internal combustion engine (11);
a motor (21) that can generate drive power of the vehicle when being supplied with the electric power;
a generator (22) that is driven by the internal combustion engine (11) and can generate the electric power;
a first secondary battery (31) that can supply the electric power to the motor (21);
a second secondary battery (32) that can be charged with the electric power generated by 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),
the power control method for the hybrid vehicle comprising:
supplying the 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.
