Hybrid
Vehicle
Combine
the benefits of gasoline engines and electric motors
and can be configured to obtain different objectives,
such as improved fuel economy, increased power, or
additional auxiliary power for electronic devices
and power tools

HYBRID
SYNERGY DRIVE uses synchronous A/C motors, which
can efficiently produce strong torque up into
the high revolution ranges and provide freedom
to control the motors revolutions and torque.
A parallel hybrid system uses both an electric
motor and an internal combustion engine to drive
the wheels. The basic components are an electric
motor, an internal combustion engine, a battery,
an inverter and |
a
transmission.The
parallel hybrid system, the motor is powered by the
battery to drive the wheels, and is also used as a generator
to recharge the battery. Consequently, the motor cannot
be used to generate electricity while the car is running.
Its basic components are electric motors, an internal
combustion engine, a generator, a battery and an inverter.
A small displacement internal combustion engine is turned
on to intermittently turn the generator to supply electric
power directly to the motor or to recharge the battery
as the car runs. The name "Series Hybrid"
is derived from the fact that the power produced by
the internal combustion engine is connected in series
to the electric motors. In addition to being light-weight
and having a long service life, the high power output
nickel metal hydride (Ni-MH) battery used in the HYBRID
SYNERGY DRIVE system provides a high input/output to
weight ratio (power output in relation to weight). It
does not require recharging from an outside power source,
nor does it require periodical replacement. The connection
structure of the cells (individual batteries) has been
redesigned and different materials are employed for
the electrodes resulting in lower internal resistance.
Furthermore, the system maintains the battery charge
at a constant level at all times by monitoring and computing
the cumulative amount of discharge under acceleration,
and recharging by regenerative braking or with surplus
power under normal running conditions. This avoidance
of excessive battery draining/recharging is another
reason for the long life of the battery.
For
market trends, the hybrid-electric vehicle market,
which has already branched into most major vehicle
classes, receives another couple high-profile nameplates
this model year in the Toyota Camry Hybrid and Nissan
Altima Hybrid. Each averaging 39 miles per gallon
in combined city/highway driving, these cars offer
new options to consumers seeking clean and ultra-efficient
mobility in a midsize sedan. On the conventional vehicle
front, models continue to receive advanced, environment-friendly
technologies. Cylinder deactivation, the recent fuel-saving
engine design in which some cylinders shut off when
maximum power is not needed, is being incorporated
into greater numbers of vehicles this year.
