Electric Vehicle
An electric vehicle is driven using a
battery and an electric motor. While
general vehicles use an internal
combustion engine and gasoline as
fuel, electric vehicles use electrical
energy that is charged inside the
high voltage battery. As a result,
electric vehicles are eco-friendly in
that they do not require fuel and do
not emit exhaust gases.
Characteristics of Electric
Vehicles
1. It is driven using the electricalenergy that is charged inside the
high voltage battery. This method
prevents air pollution since fuel,
like gasoline, is not required,
negating the emission of exhaust
gases.
2. A high performance motor is used in the vehicle as well. Compared
to standard, internal combustion
engine vehicles, engine noise and
vibrations are much more minimal
when driving.
3. When decelerating or driving downhill, regenerative braking is
utilized to charge the high voltage
battery. This minimizes energy
loss and increases the distance to
empty.
4. When the battery charge is not sufficient, normal charge, quick
charge and trickle charge are
available. (Refer to "Charge Types
for Electric Vehicle" for details.)
Information
What does regenerative braking do?
It uses the electric motor when decel-
erating or braking which transforms
vehicle motion (kinetic energy) to elec-
trical energy to charge the high volt-
age batteries. (Torque is applied in the
opposite direction when decelerating
to generate braking force and electric
energy.)
Battery Information
• The vehicle is composed of a highvoltage battery that drives the
motor and air-conditioner, and an
auxiliary battery (12 V) that drives
the lamps, wipers, and audio sys-
tem.
The auxiliary battery is automati- cally charged when the vehicle is in
the ready ( ) mode or the high
voltage battery is being charged.

On-Board Charger (OBC) : External device (low speed) to charge the high
voltage battery.
Inverter : Transforms direct current into alternate current to supply power
to the motor, and transforms alternate current into direct current to charge
the high voltage battery.
LDC : Transforms power from the high voltage battery to low voltage (12 V)
to supply power to the vehicle (DC-DC).

Reduction Gear
Main Components of Electric Vehicle
Motor : Uses electrical energy
stored inside the high voltage bat-
tery to drive the vehicle (functions
like an engine in a standard vehi-
cle).
Reduction Gear : Delivers rota-
tional force of the motor to the tires
at appropriate speeds and torque.
High voltage battery (lithium-ion
polymer) : Stores and supplies
power necessary for the electric
vehicle to operate (12 V auxiliary
battery provides power to the vehi-
cle features such as lights and
wipers).

High Voltage Battery (lithium-
ion polymer)
The charge amount of the highvoltage battery may gradually
decrease when the vehicle is not
driving.
The battery capacity of the high voltage battery may decrease
when the vehicle is stored in
high/low temperatures. Distance to empty may vary
depending on the driving condi-
tions, even if the charge amount is
the same. The high voltage battery
may expend more energy when
driving at high speed or uphill.
These actions may reduce the dis-
tance to empty.
The high voltage battery is used when using the air-conditioner /
heater. This may reduce the dis-
tance to empty. Make sure to set
moderate temperatures when
using the air-conditioner/heater.
Natural degradation may occur with the high voltage battery
depending on the number of years
the vehicle is used. This may
reduce the distance to empty.
When the charge capacity and dis- tance to empty keep falling, con-
tact an authorized HYUNDAI deal-
er for inspection and maintenance.
•Do not intentionally remove or
disassemble high voltage
components and high voltage
battery connectors and wires.
Also, be careful not to dam-
age high voltage components
and the high voltage battery. It
may cause serious injury and
significantly impact the per-
formance and durability of the
vehicle.
When inspection and mainte-
nance is required for high volt-
age components and the high
voltage battery, contact an
authorized HYUNDAI dealer.
WARNING
OAEEQ016002

H6
If the vehicle will not be in use foran extended period of time, charge
the high voltage battery once every
three months to prevent it from dis-
charging. Also, if the charge
amount is not enough, immediate-
ly charge to full and store the vehi-
cle.
Normal charge is recommended to keep the high voltage battery in
optimal condition.
If the high voltage battery charge
amount is below 20%, you can
keep the high voltage battery per-
formance in optimal condition if
you charge the high voltage battery
to 100%. (Once a month or more is
recommended.)High Voltage Battery Warmer
System
The high voltage battery warmer
system prevents reduction of battery
output when battery temperature is
low. If the charging connector is con-
nected, the warmer system automat-
ically operate according to the bat-
tery temperature.
Charging time may shorten compare
to vehicles without the high voltage
battery warmer system. But, electric-
ity charge may increase because of
high voltage battery warmer system
operation.Make sure to use a designated
charger when charging the
high voltage battery. Using dif-
ferent types of chargers may
have a serious impact on vehi-
cle durability.
Make sure that the high volt-
age battery charger gauge
does not reach ''L (Low)". If the
vehicle is kept at ''L (Low)" for
a long period, it may damage
the high voltage battery and
the high voltage battery may
have to be replaced depending
on the level of degradation.
If the vehicle is in a collision,
contact an authorized HYUNDAI
dealer to inspect whether the
high voltage battery is still con-
nected.
CAUTION
The high voltage battery warmer
system operates when the charg-
ing connector is connected to
the vehicle.
However, the high voltage
warmer system may not operate
when battery temperature drops
below -31°F (-35°C).
