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 electricalenergy 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 energyloss and increases the distance to
empty.
4.When the battery charge is not suf- ficient, AC charge, DC 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 high voltage 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.

Main Components
On-Board Charger (OBC) :
A device that charges the high volt-
age battery by converting AC
power from a charging station to
DC power.
• Inverter : A device that transforms
direct current (DC) from the high
voltage battery into alternating cur-
rent (AC) to supply power to the
electric motor and transforms AC
back into DC when available to
charge the high voltage battery.
LDC : An LDC is a Low Voltage
DC-to-DC converter that trans-
forms power from the high voltage
battery to the low voltage battery
(12V) in order to supply electrical
power to the vehicle to operate the
lights, wipers, multimedia, etc. Electric Motor :
A device that con-
verts electrical energy from the
high voltage battery into mechani-
cal energy which is then trans-
ferred as rotational torque to the
wheels in order to drive the vehi-
cle.
Reduction gear : Delivers rota-
tional force of the motor to the tires
at appropriate speeds and torque.
EV Battery (Lithium-ion) : On
board high voltage storage devicewith a capacity up to 64 kWh
❈ OBC : On-Board Charger
❈ LDC : Low Voltage DC-DC
Converter
Do not remove or disassem-
ble high voltage components
and high voltage battery con-
nectors and wires. Also, be
careful not to damage high
voltage components and the
high voltage battery. It may
cause serious injury and sig-
nificantly impact the perform-ance and durability of the
vehicle.
When inspection and mainte-
nance is required for high volt-
age components, contact an
authorized HYUNDAI dealer.
WARNING

H5
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.
If the vehicle will not be in use for an extended period of time, charge
the high voltage battery once every
three months to prevent it from dis-
charging. Also, if the chargeamount is not enough, immediate-
ly charge to full and store the vehi-
cle.
AC charge is recommended to keep the high voltage battery inoptimal 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 isrecommended.)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 HYUNDAIdealer to inspect whether the
high voltage battery is still con-nected.
CAUTION

H6
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.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 -35°C (-31°F).

Energy Information
Select ‘EV Energy Information’ on
the screen.
You can check battery information and energy consumption.
Battery information
You can check the vehicle expected
range, total battery power remaining,
and expected charging time for each
charge type.
The displayed range is calculated based on the real time energy effi-
ciency while driving. The displayed
range may change as the driving
pattern or conditions change.
Note that the range may be differ- ent from a given state of charge
(SOC%) depending on drive mode,
drive conditions, and driving pat-
terns.
Energy consumption
You can check the current energy
consumption for each system of the
vehicle. ➀ ‘Driving’ shows the total power and
energy consumption of the electric
motor kW usage when driving and
kW storage when regenerative
braking is applied.
➁ ‘Climate’ shows the power and
energy consumption which are
used by the heater or air condition-
er.
➂ ‘Electronics’ shows the power and
