Main Components of Electric
Vehicle
• On-Board Charger (OBC) : A device
that charges the high voltage battery
by converting AC power of the power
grid to DC power.
• 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).
• VCU : Control the various controls on
the vehicle.
• Motor : Uses electrical energy stored
inside the high voltage battery to drive
the vehicle (functions like an engine in
a standard vehicle).
• Reduction gear : Delivers rotational
force of the motor to the tires at
appropriate speeds and torque.
• High voltage battery (lithium-ion
battery) : Stores and supplies power
necessary for the electric vehicle
to operate (12 V auxiliary battery
provides power to the vehicle features
such as lights and wipers).

à OBC : On-Board Charger

à LDC : Low Voltage DC-DC Converter

à VCU : Vehicle Control Unit
WARNING
• Do not intentionally remove
or disassemble high voltage
components and high voltage
battery connectors and wires. Also,
be careful not to damage high
voltage components and the high
voltage battery. It may cause serious
injury and significantly impact the
performance and durability of the
vehicle.
• When inspection and maintenance
is required for high voltage
components and the high voltage
battery, contact an authorized
HYUNDAI dealer.
High Voltage Battery
(lithium-ion battery)
• The charge amount of the high
voltage battery may gradually
decrease when the vehicle is not
being driven.
• 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 conditions
(such as outside temperature), 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 distance to empty.
• The high voltage battery is used when
using the air-conditioner / heater.
This may reduce the distance to
empty. Make sure to set moderate
temperatures when using the air-
conditioner/heater.

Charging current
ONE1Q011030L
• You can adjust the charging
current for an AC charger. Select an
appropriate charging current.
• If the charging process does not
start or abruptly stops in the middle,
reselect another proper current and
re-try charging the vehicle.
• Charging time varies depending on
which charging current is selected. Winter ModeONE1Q011031L
You can select or deselect the Winter mode.
The Winter mode is efficient during
the winter time when the high voltage
battery temperature is low.
This mode is recommended to improve
driving and DC charging performances
during winter by raising the battery
temperature to an adequate level.
However, the driving distance may be
reduced as the energy is required to
increase battery temperature.
Also, if the battery temperature is low during driving or when scheduled air
conditioner/heater is activated, this
mode is operated to improve driving
performance.
However, the mode is not operated to
ensure driving distance when the battery
level is low.
Information
This mode is available for the vehicles
equipped with the battery heater.

Virtual Engine Sound System
The Virtual Engine Sound System
generates engine sound for pedestrians
to hear vehicle sound because there is
no sound while the Electric Vehicle (EV)
is operating. • If the vehicle is in the ready (
)
mode and the gear is not in P (Park),
the VESS will be operated.
• When the gear is shifted to R
(Reverse), an additional warning
sound will be heard.
CAUTION
• The vehicle is much quieter while
driving than a conventional gasoline-
powered vehicle. Be aware of your
surroundings and always drive safely.
• After you park the vehicle or while
you are waiting at a traffic light,
check whether there are children or
obstacles around the vehicle.
• Check if there is something behind
the vehicle when driving in reverse.
Pedestrians may not hear the sound
of the vehicle.
Distance to Empty
ONE1Q011049E
The distance to empty is displayed
differently according to the selected
drive mode in the Drive Mode Integrated
Control System.
For more information, refer to “Drive
Mode Integrated Control System” in
chapter 6.
When destination is not set • On average, a vehicle can drive about
199 miles (320 km) (Standard type) /
249 miles (400 km) (Extended type).
• Under certain circumstances where
the air conditioner/heater is ON,
the distance to empty is impacted,
resulting in a possible distance range
from 106 ~ 286 miles (170 ~ 460 km)
(Standard type) / 130 ~ 354 miles
(210 ~ 570 km) (Extended type).
When using the heater during cold
weather or driving at high speed, the
high voltage battery consumes a lot
more electricity. This may reduce the
distance to empty significantly.
• After ‘0 km’ has been displayed,
the vehicle can drive an additional
2~5 miles (3~8 km) depending on
driving speed, heater/air conditioner,
weather, driving style, and other
factors.

•
Distance to empty that is displayed
on the instrument cluster after
completing a recharge may vary
significantly depending on previous
operating patterns.
When previous driving patterns
include high speed driving, resulting
in the high voltage battery using more
electricity than usual, the estimated
distance to empty is reduced. When
the high voltage battery uses little
electricity in ECO mode, the estimated
distance to empty increases.
• Distance to empty may depend on
many factors such as the charge
amount of the high voltage battery,
weather, temperature, durability of
the battery, geographical features,
and driving style.
• 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 destination is set
When the destination is set, the distance
to empty may change. The distance
to empty is recalculated using the
information of the destination. However,
the distance to empty may vary
significantly based on traffic conditions,
driving habits, and condition of the
vehicle.
Tips for Improving Distance to
Empty
• If you operate the air conditioner /
heater too much, the driving battery
uses too much electricity. This
may reduce the distance to empty.
Therefore, it is recommended that
you set the cabin temperature to
22°C AUTO. This setting that has
been certified by various assessment
tests to maintain optimal energy
consumption rates while keeping the
temperature fresh.
Turn OFF the heater and air
conditioner if you do not need them.
• When the heater or air conditioning
system is on the energy consumption
is reduced if recirculation mode is
selected instead of selecting the fresh
mode. The fresh mode requires large
amount of energy consumption as
the outside air has to be re-heated or cooled.
• When using the heater or air
conditioning system use the DRIVER
ONLY or scheduled air conditioner/
heater function.
• Depress and hold the accelerator
pedal to maintain speed and drive
economically.
• Gradually depress and release the
accelerator pedal when accelerating
or decelerating.
• Always maintain specified tire
pressures.
• Do not use unnecessary electrical
components while driving.
• Do not load unnecessary items in the
vehicle.
• Do not mount parts that may increase
air resistance.
