Glossary of Hybrid Technology Terms (continued)
Hybrid Battery
Composed of sealed Nickel-Metal Hydride (NiMH)
modules, the 288-volt hybrid battery provides electric
motor power during start-up, acceleration,
uphill driving, and reverse. It also stores energy
captured during regenerative braking. The hybrid battery is covered for 8
years/100,000 miles which ever occurs first. In normal use, we expect the
battery to last longer than the length of this warranty.
Lexus Hybrid Drive
Lexus hybrid technology that combines an advanced
gasoline engine, electric motor/generators, a hybrid
battery, an Electronically-controlled Continuously
Variable Transmission (ECVT) and advanced electronic
controls to provide powerful acceleration, responsive and smooth performance,
economy in economy driving conditions, and very clean tailpipe emissions.
Inverter
The inverter converts the hybrid battery's high voltage
DC current into AC current for the electric motors and
vice versa, depending on driving demands and the
needs of the electrical system. The inverter can also
boost the battery's power up to 650 volts as needed for maximum power.
kW (Kilowatts)
A unit of instantaneous electrical power equal to 1000 watts or 1.34
horsepower.
Motor/Generator (MG1)
In a hybrid vehicle, the word "motor" refers to an
electric motor which works with the vehicle's engine
to efficiently drive the vehicle.
The LS 600h L uses permanent magnet AC motors:
an electric starter motor/generator (MG1), and an electric drive motor (MG2).
