Planetary gear set
The component of the ECVT that delivers the efficient
mix of engine and electric power to the rear wheels.
The operation of the planetary gear set helps provide
responsive and smooth acceleration. The LS 600h L
uses a compact, double planetary Ravigneaux-type geartrain to provide low
and high drive, to maximize performance or economy in economy driving
conditions.
Regenerative Braking
Regenerative braking is a feature that allows an
electric motor to act as a generator when braking.
It converts the kinetic energy of the car's motion into
electrical energy. Whenever the LS 600h L is braking
or slowing, the electrical energy made during regenerative braking is used to
recharge the hybrid battery and is measured in Watt Hours (Wh) on the
Consumption Monitor screen.
Volt
The unit of measure for voltage. Voltage is the electrical pressure which causes
current to flow in an electrical circuit.
Watt
A unit of electrical power. One watt equals 1/746th horsepower.
Wh (Watt hours)
Electrical power used, or in the case of the LS 600h L,
regenerated and measured in terms of time.
