초록 ▼

In a power output apparatus (20) of the present invention, a controller (80) controls a clutch motor (30) and an assist motor (40), thereby converting energy output from an engine (50) and expressed by the product of the revolving speed and the torque of a crankshaft (56) of the engine (50) to energy expressed by the product of the revolving speed and the torque of a drive shaft (22) and outputting the converted energy to the drive shaft (22). When the remaining charge of a battery (94) is less than a predetermined range, the battery (94) is charged with electric power, which is regenerated from part of the energy output from the engine (50) by either the clutch motor (30) and the assist motor (40). When the remaining charge of the battery (94) exceeds the predetermined range, on the other hand, part of electric power consumed by either the clutch motor (30) or the assist motor (40) is supplied by electric power released from the battery (94). These procedures enable the remaining charge of the battery (94) to be kept within the predetermined range.
