ABOUT MULTI-PURPOSE ELECTRIC VEHICLE
gKAZh
KAZ
is a high performance and highly functional vehicle compared with a
conventional ICE (Internal Combustion Engine) MPV (Multi Purpose Vehicle) thanks
to the development of new component technologies and system technologies.
KAZ was
designed from the ground up and has, therefore, not been converted from an ICE
MPV, making the design of the body very flexible.
KAZ
uses three innovative component technologies. The Lithium-ion battery was the
most important in order to supply a high energy and high power to KAZ. The
Intelligent Power Module (IPM) was useful to make inverters with low energy
loss and of a compact size. The motors realised with Nd-Fe Rare Earth magnets
are highly efficient, with high torque and high-speed with a compact size.
KAZ
is composed of three newly developed technologies.
1.
In-Wheel drives assemble a motor, a reduction gear system, a mechanical brake
and a wheel bearing inside a driving wheel. It decreases the transmission loss
between a motor and a wheel, reduces the total weight of the vehicle and
increases the useful space in the cabin. KAZ uses eight In-Wheel drive with
55kW (73PS) maximum power in each wheel. It means the total output power of KAZ
is 440kW (590PS).
2.
The components built-in frame integrates all batteries and electric components
inside the strong floor structure. It makes the vehicle lighter in weight,
leaves more space to be set aside for the passenger compartment and gives a
lower center of gravity. As the height of the integrated chassis is 15cm, the
lower height of KAZ is almost the same as a conventional sedan and much lower
than a conventional MPV, thus making access much easier.
3.
The tandem suspension system is based on pairs of wheels with hydraulic
control. It decreases the wheelhouse to the minimum possible and makes driving
very comfortable and very stable.
To
make electric vehicles socially acceptable, performance and functions must be
superior to those of existing cars. Until now, the battery (energy storage)
limited the range and autonomy of an electric vehicle. This, together with lack
of acceleration and poor top speeds, are the main reasons why such vehicles
have not become popular. The size of the batteries meant that vital space had
to be given up by the passenger compartment, making electric vehicles far less
versatile in use. KAZ aims to free electric vehicles of their limits based on
the following three basic concepts:
a.
Ground-up design,
b.
Collection of best technology,
c.
Adoption of technologies peculiar to electric vehicle.
Thanks to
ground-up design, new component technologies and newly developed system
technology, KAZ has a very high performance. The maximum speed is 311km/h, 0-400m
acceleration time is 15.3 sec and range per charge will be 300km using the
Lithium-ion battery. The range will increase to 600Km with a range extender
(output power 10kW) which is currently under development.
KAZ
is a Zero-Emission electric vehicle with highly innovative features which
really takes care of environmental issues and addresses energy problems with
its highly efficient power source.
KAZ
means peace and it is the first prototype to come out of this important
research project into highly functional electric vehicles for the 21st century.
KAZ is very stable and comfortable. No tail squat in acceleration and no dive
in braking because of a low center of gravity and eight-wheel drive.
Acceleration feeling is perfect because the torque of the motor is constant
from zero to higher speed.
KAZ
handles very well. Vibration on a rough road is reduced because of the function
of tandem suspension system. Cornering is stable because of a low center of
gravity, eight-wheel drive and tandem suspension system.
KAZ
of course is environmental friendly. No pollution and low noise when it is run.
The energy efficiency is around 1.7 times that of a conventional car.
KAZ
has an interesting appearance which is a modern interpretation of MPV designed by
the team at I.DE.A Institute, where this first running prototype was also
developed and built.
KAZ
technology can be applied to all kinds of vehicles, for example a completely
low and flat floor minibus, a low floor and large space van or a high performance
passenger car.
