KIA Soul EV: Russian premiere at the MIAS 2014
Moscow, August 27, 2014 At the Moscow International Motor Show 2014 the Russian premiere of KIA Soul EV.
Retaining the recognizable "family resemblances" recently released on the market of secondgeneration Russian
KIA Soul Soul EV is the first electric vehicle brand, intended for sale in the world. Serial production of the model
was launched in June 2014.
President of KIA Motors Rus Mr. Kim Sunghwan talks about the new product: «Soul EV is not just a stylish car
that attracts attention. It retains all of the same high quality standards that are demanding modern buyer expects
car brand KIA. It is subject to the same unique factory warranty is offered for KIA vehicles on traditional fuels. Soul
EV equally attractive regardless of how choices are made mind or heart. He is fully consistent with our brand
strategy offering customers stylish cars that provide a minimum of adverse effects on the environment and at the
same time has an excellent value for money. "
Iconic design of a modern model
Soul EV retained in its design the same principle as the Soul of the second generation with internal combustion
engines: fully updated, more "adult" look, while maintaining the absolute recognition appearance that brought
worldwide popularity first generation KIA Soul. The most noticeable difference Soul EV from their counterparts on
traditional fuels is the twotone paint with contrasting emphatic "floating" roof line, the original design of 16inch
alloy wheels and LED rear optics. On the front fenders, near the base of the roof rack placed special distinctive
badges «ECO ELECTRIC». Electric car also received the original design of the front and rear body panels, and the
front grille of the increased size provides sockets for connecting the charger connector.
For Soul EV developed a new interior design: use more high quality materials and architecture front panel is more
focused on the driver.The electric car is the first model of KIA, equipped entirely new dashboard, made by
technology OLED (organic liquid crystals). Twocolor trim scheme gives a feeling of spaciousness, openness and
fullness air. The twovolume decorative trim on the front panel of a soft material also visually adds to her sense of
Audiotsentr with builtin navigation (AVN) for Soul EV shift from "normal» Soul, however, received a number of
additional features designed just for the new features, the electric model. Among them the timer setting cabin
ventilation and charging timer. Also standard set of functions that allow the driver to not worry about the power
reserve. He provided information about the actual energy consumption and the ability to use the search the nearest
charging station, and the display of the navigation system displays information about the range of up to the next
Bestinclass battery charge density
Soul EV motor has a power of 81.4 kW (110 hp) and a torque of 285 Nm. Battery lithiumion polymer batteries have
high power reserve (27 kWh) and is located under the floor of the cabin. Traction motor is transmitted to the front,
drive wheels via a stepless gearbox, allowing the electric vehicle to accelerate to 100 km / h in less than 12
seconds and a maximum speed of 145 km / h. Real power reserve of about 200 km.
Effective layout of the electric motor and other electronic systems allow designers to reduce the mass of the battery
and reduce the amount lost by her in the storage space in the cabin. One of the most important achievements of
engineers was the firmness of the charge that has been made in creating battery: value of 200 Wh / kg suggests a
bestinclass energy content relative to the total mass of the batteries.
Work on developing the battery was conducted for three years jointly by KIA Motors and experts from leading
Korean company in the field of alternative energy sources SK innovation. The project's goal was to achieve
maximum efficiency, as well as the creation of the electrolyte composition capable of providing a stable battery
performance at both high and low ambient temperatures. Achieve a more efficient transfer of energy has allowed a
reduced internal resistance, achieved by using cathodes of nickelcobaltmagnesium alloy and carbongraphite
Using the lithiumion polymer battery (compared to the more common lithiumion) led to a higher charge density.
In this case, a simpler design of cells reduces the cost of production, better layout capabilities and a wider range
of temperature control.
According to the principles of maximum security in case of an accident, which adheres to the KIA plate separators
each cell received a ceramic coating that provides mechanical protection for the battery. Special overcharge
protection circuit monitors the temperature of the battery and the electric current at each time point.
To achieve better performance and increase the power reserve Soul EV allowed regenerative system that converts
kinetic energy into electrical energy electric every time he deceleration or braking. The driver has the possibility of
selecting between three modes intensity recovery depending on whether he wants to notice an auxiliary force to the
brakes and what percentage of energy required to obtain a recovery process.
You can choose between two different driving modes: Drive and Brakes. Mode Brakes (braking) allows for the
"return" the maximum possible amount of energy from the regenerative braking system. Each of these modes can
also be activated in a special ECOmode, allowing further increase the reserve of Soul EV. This is achieved by
optimizing the performance and energy consumption of ventilation systems, heating and air conditioning, as well
as directly to the motor.
Soul EV is equipped with a heating system battery. It provides thermal insulation batteries and preheating, which
reduces the negative impact on the charge level of the low external temperatures.
Included in standard equipment Soul EV charger AC power 6.6 kW allows a full charge an electric vehicle for 5
hours. This figure may vary slightly depending on the characteristics of the used power supply. 80 percent charge
level in the "quick charge" with the 100kW DC device is achieved in 25 minutes, and when using a 50kilowatt unit
for 33 minutes.
New technologies that increase the efficiency of heating, ventilation and airconditioning
Already at a very early stage of design engineers KIA formulate the problem in principle to reduce the energy
consumption of heating, ventilation and air conditioning (HVAC). In the most severe operating conditions, with
maximum use of devices HVAC reduction of electric power reserve can reach 50%. To cope with this problem,
experts KIA developed and used to create the Soul EV four new technologies that are directly related to the HVAC.
These technologies include a new highdesign of the heat pump, the intelligent air intake system, individual mode
of ventilation for the driver and blower on a predetermined schedule.
New heat pump uses the energy released in the process of airconditioning and power electrical systems and
thus increases the efficiency of the heating system and ventilation. Additional regenerated energy is directed to
heat the cabin, reducing the consumption of electricity from the main battery.
The heat pump consists of a compressor, evaporator and condenser. It allows the heating and ventilation systems
Soul EV use the heat generated during operation of electrical devices. Instead of spending for heating the
passenger compartment exclusively obtained from the main battery electricity heat pump recirculates it radiant
heat, redirecting it to the needs of heating and ventilation systems, and increasing the energy efficiency of HVAC.
Reducing the load on the main battery, this solution allows to increase the total mileage Autonomous Soul EV.
In conjunction with a heat pump works and intelligent air intake as accurately controlling the amount supplied to
the interior and exhaust air out of it, as well as the humidity level in the cabin. This system recirculates the air that
has already been heated or cooled air conditioning or heater to the desired temperature, and then dosed mixes it
with the best of fresh air from the outside of the cabin. By optimizing the air flow in the cabin, the HVAC system is
able to operate more efficiently by reducing the work of the heater or air conditioner while driving. To control the
supply of fresh air into the cabin system manipulates data humidity sensors, temperature control and drive the
external air intake.
For the first time on a production car in principle on Soul EV system used individual ventilation. It reduces energy
consumption, providing ventilation and heating only directly to the driver's seat. The remaining ducts both upper
and lower completely disconnected from the circuit HVAC. This is the fundamental difference between the system
of circuits, traditionally used in modern cars: usually overlap of a duct simply redirects the flow of cold or hot air
ducts in the other, without reducing the overall load on the air conditioner or heater and reducing the consumption
of these energy systems.
Individual ventilation mode is activated by pressing the "driver only" on the instrument panel and provides a
comfortable environment for the driver's seat with a minimum of energy, helping to achieve more autonomous path
of an electric vehicle.
Soul EV is equipped with a new system of preair conditioning, heating and ventilation of salon timer. This solution
is used for KIA cars for the first time. Management of heating and ventilation systems through a common control
interface, and the owner can set the preheating or cooling of the air in the cabin. It is activated for 30 minutes
before starting the engine, while Soul EV still plugged in for recharging.Cooling or heating air to a predetermined
temperature by the driver comes before work begins the main battery electric vehicle. Thus reducing the load on
the battery when disconnected from the network and the beginning of autonomous movement.
Effective layout solutions for Soul EV
Fundamentally bodywork Soul EV similar versions of the second generation of Soul with internal combustion
engines, but also applied a number of specific design solutions designed specifically for electric vehicles. They
are primarily related to the further strengthening of the body structure and layout, providing accommodation battery
with minimal impact on the useful volume of the cabin.
One of the most important of these decisions has been the emergence of five crosspower beams under the body
to secure the battery and make the body more torsional rigidity. In the power structure of the Body Soul EV also
widely used in ultrahigh steel in the first place to strengthen the Bpillars and sills. Win the use of highstrength
steel is 37.1% (in versions with internal combustion engine 35.0%). All these decisions have led to 27% to
improve torsional stiffness of the body relative to the "nonelectric" versions, though for the Soul of the second
generation, and so the rate was improved by 29% compared to its predecessor.
The principal challenge for the engineers when creating KIA Soul EV was the development of such an
arrangement, in which the battery is quite heavy, placed under the floor of the cabin took up a minimum of storage
space, which is famous for KIA Soul. As a result of these calculations has been achieved that the stock of legroom
in the back row was reduced by only 80 mm, and the shape of the rear seat cushion provides higher location
knees passengers, which compensates for the loss of space. Part of the space under the boot floor, which is in
the "normal» Soul hiding compartment at Soul EV set aside for storage of the charging cable. Repair kit for tire
placed in the same compartment under the boot floor, and that version of Soul with internal combustion engines.
The result of the engineers and designers is that associated with the appearance of an additional battery pack
loss of usable volume in Soul EV are a record low against the competition. External dimensions Soul EV while the
dimensions are identical versions of Soul with petrol or diesel engines.
Improved ride and handling
Soul EV provides excellent ride comfort and confident handling in urban environments. Due to the increased rigidity
of the body compared to a "normal» Soul the designers managed to improve driving performance electric vehicle.
Location battery under the floor of the passenger compartment has significantly lower center of gravity and get a
better sense of stability in motion. Soul EV fully supports the longstanding reputation as a KIA Soul interesting in
the management of the car with the energetic character.
Protection against noise and vibration in the Soul EV also improved relative to the "base» Soul. Due to the lack of
noise from the petrol or diesel engine, as well as due to less, than its competitors, the effect of "howl" when the
motor a major challenge for engineers KIA in working through fine tuning Soul EV in additional measures to
reduce mechanical vibrations, noise and tire aerodynamic noise.
Electric suspension provides better energy consumption, and the original design of wheels makes them 15%
more rigid, reducing the level of vibration. The casing battery disposed under a floor is shaped to better
aerodynamic qualities and reducing noise from the air flow.Favorable impact on the level of noise and vibration
using modern environmentally friendly noise insulation materials in finishing the front panel, the engine
compartment and on the board of the engine compartment at the base of the windshield.
Another original solution was the use of tires with ultralow rolling resistance. They are designed from the
company Kumho tire manufacturers directly for the Soul EV and have the dimension 205/60R16. Use of a special
compound and the original profile of the tire reduces rolling resistance by 10%, even with respect to the
characteristics of tires with low rolling resistance. Of fundamental importance in this case is that achieved no
negative impact on ride comfort, handling, noise, and braking performance tires.
