THS II (Toyota Hybrid System II)
D The '07 Camry Hybrid model is powered by a THS II (Toyota Hybrid System II), which has been
developed under a "Hybrid Synergy Drive" concept to pursue better environmental performance and to
realize "fun to drive" feeling. Under this concept, the THS II has achieved significant advances in control
systems, which aim for synergy between the power of the motor and the power of the engine. By greatly
boosting the power supply voltage, this system has achieved a high level of balance between
environmental performance and power.
D This hybrid system consists of a high efficiency 2AZ-FXE engine and a high speed, high power output
MG2 (Motor Generator No.2), which cooperate optimally through a hybrid transaxle that excels in
transmission performance. Furthermore, this system uses a high-output HV battery with a nominal voltage
of DC 244.8 V, which is supplied to MG1 (Motor Generator No.1) and MG2 by a variable-voltage system.
The variable-voltage system has a boost converter, which boosts the operating voltage of the system to
a maximum voltage of DC 650 V, and an inverter, which converts it into an alternating current.
Through these elements, the dynamic performance of a class above has been realized, in addition to
realizing a high level of regenerative capability. Together with the highly efficient cooperative control of
the engine and the motor, a dramatic fuel economy performance has been realized.
