Korea start to develop the zero emission
vehicles from Seoul Olympic on 1988. Fossil fuel vehicle
continue to occur much air pollution. By government will
be more and more made to tight the environment rule against
vehicle.
In 1991, Hyundai Motor Company launched Sonata EV that
originally designed production passenger car.
Ministry of Environment make the schedule distribute
Hybrid vehicle at public organization in 2004 and buy
350 Hybrid vehicle.
 Fuel Cell Vehicles
Fuel cell vehicles feature higher fuel efficiency than
hybrid electric vehicles, the fuel supply convenience
of gasoline vehicles, and the quietness similar to
that electric vehicles. With the use of hydrogen
as fuel, they do not produce any exhaust emissions.
Fuel cell technology was first used to provide spaceships
with a power source and astronauts with the water
they needed to survive in outer space. When fuel
cell technology advances in terms of price, performance
and safety so that such a system can be mounted on
vehicles, the system will also be applied to vessels,
buildings, small-scale power plants, submarines and
low-noise vehicles, and mobile communications. If
the industrialization of the 20th century can be
characterized by the development of the internal-combustion
engine, the 21st century will be called the age of
fuel cells.
Hybrid Vehicles
By making up for the weaknesses of internal-combustion
and electric vehicles, hybrid electric vehicles can
both reduce exhaust emissions and improve fuel consumption
and power performance. The power transmission system
of a hybrid electric vehicle features the integration
of the driving parts including the engine and motor.
The motor mounted on a hybrid electric car performs
the roles of both engine assister and generator at
the same time and can charge the car battery without
an outside charger when the car is running or braking.
The hybrid electric vehicle operates in various driving
modes depending on driving conditions to save energy
and reduce exhaust emissions, thus realizes higher
fuel economy, more efficient driving, and a higher
level of quietness and comfort than existing internal-combustion
engine vehicles.
Electric Vehicles
From the 1990s, All country have given more and more
attention to the development of electric vehicles
and have actively pursued the technologies needed
to make them for environment. Korea automaker has
also made enormous investments in the research and
development of electric vehicles beginning with the
development of the Sonata electric car in 1991 by
Hyundai motor company. Currently, the Santa Fe electric
vehicle enables the car to travel 160km per one-time
charge, a battery controller, a driving motor, a
charger mounted on the controller, a direct current
converter, etc. The electrical energy stored in the
battery supplies the power source to the running
motor through the motor controller, thus driving
the wheels of the vehicle. When speed is reduced,
the recovered energy is stored in the battery, realizing
a highly efficient cycling of energy.
