In a power output apparatus 10, a complex motor 30 includes a stator 32, a rotor 34 linked with a crankshaft 56 of an engine 50, and a rotor 36 linked with a drive shaft 22, wherein the stator 32 and the rotor 34 constitute a first motor MG1 constructed as an induction motor and the stator 32 and the rotor 36 constitute a second motor MG2 constructed as an induction motor. A driving circuit 92 regulates the frequency of an exciting electric current to be flown through three-phase coils 38 of the stator 32 within a range between the frequency of the rotor 34 and the frequency of the rotor 36. This procedure enables the first motor MG1 and the second motor MG2 to function respectively as a generator and a motor. Electromagnetic energy regenerated by the first motor MG1 is supplied to the second motor MG2 not via the driving circuit 92 but directly from the stator 32. Compared with a system for driving a motor via a driving circuit, such as an inverter, the structure of the present invention enhances the energy efficiency of the power output apparatus 10 and reduces the size of the whole power output apparatus 10.

In response to connection of a vehicle with an external power supply, a PLG-ECU performs a first charging operation of controlling a charger using a target value which is set to a state of charge lower than a predetermined full state of charge, until the state of charge of a power storage device reaches the target value. After the state of charge reaches the target value, the PLG-ECU stops charging of the power storage device, and restarts charging of the power storage device so that the state of charge reaches the predetermined full state of charge at a scheduled time to end charging which is specified through the use of an input unit.

A control apparatus for controlling an output torque of a brushless electric motor based on a torque command signal received from a torque command signal generator. The control apparatus includes magnetic pole position sensors for producing position signals indicative of a rotational position of a rotor of the motor. A counter outputs an address signal based on the position signals. A sine wave memory, which stores plural sine waves, outputs a sine wave signal based on the address signal. Then the amplitude of the sine wave signal is linearly controlled based on the torque command signal, and stator current is applied to stator windings of the motor based on the linearly controlled sine wave signal.

An electric automobile driving apparatus installed in an electric automobile for driving the same. The driving force of the electric automobile is generated by a main battery as the rotating force of a motor. The motor is an AC motor and driven by an AC current output from the main battery and converted into a DC voltage by an inverter. Electric appliances installed in the automobile are driven by a DC voltage having a different value which is output from an auxiliary battery. The auxiliary battery is charged with the DC voltage obtained by rectifying the output from a secondary coil which is disposed in close proximity to a primary coil of the motor.

An accessory drive apparatus includes a power source, an accessory system that provides an input to the power source, an accessory driving source that drives the accessory system, and a power combination/distribution mechanism that is connected to the power source and the accessory system to transmit power from both the power source and the accessory driving source to the accessory system. With this arrangement, the accessory system is driven by a combination of power received from the accessory driving source and the power source.
