Glossary of Hybrid Technology Terms (continued)
Planetary gear set
The component of the ECVT that delivers the efficient
mix of engine and hybrid power to the front wheels.
The operation of the planetary gear set provides
seamless acceleration without shift points.
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 RX400h 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 (vehicles with optional Navigation Systems only).
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 RX 400h,
regenerated and measured in terms of time.
