A secondary battery is capable of storing and discharging electrical energy. Energy regenerated by the motor under deceleration is stored in the secondary battery
Plug-in hybrid vehicles are equipped with lithium-ion batteries, which have much greater capacity than conventional nickel-metal hydride batteries. Using the external battery charger, the battery is able to charge more electricity from household electrical outlets.
An AC synchronous motor and a high efficiency DC brushless motor running on AC are used in plug-in hybrid vehicle. A high performance motor has been made possible through neodymium magnet (permanent magnet) combined with a laminated electromagnetic steel plate rotor. In addition, the permanent magnets are aligned in a V-shape, the optimum configuration for maximizing torque and power output. High voltage power supply also provides large amounts of electricity. All of these refinements have resulted in the creation of an electric motor with the highest level of power-to-weight and power-to-volume ratios in the world.
Max. power output: 60 kW (82 PS)
Max. torque: 207 N·m (21.1 kgf·m)
The power control unit in plug-in hybrid vehicle consists of an inverter to convert battery-supplied DC to motor-driving AC and a voltage booster circuit that increases voltage up to 650 volts. The reactor has been modified in accordance with the improved rated voltage of the battery.
Plug-in hybrid vehicles come equipped with a battery charger, which allows the battery to be recharged from a household electrical outlet. Charging time is about 90 minutes at 200 VAC, and about 180 minutes at 100 VAC.
