Abstract

The invention provides a power control device for hybrid vehicles capable of allowing Power is generated by a generator connected to the low voltage battery regardless of the compression rate. low voltage battery charge A hybrid vehicle will include: a motor (21) that can be connected to the driving wheels (18) of the vehicle; generator (22) that can be connected to an internal combustion engine (11); First secondary battery (21) connected to the motor (21); Secondary battery (32) connected with the generator (22) and its voltage, which is lower than that of the first secondary battery (31); and a converter (33) that increases the DC voltage received from the second secondary battery (32) and can output the added DC voltage to the first secondary battery (31).
