Main Components of Electric
Vehicle
• On-Board Charger (OBC) : A device
that charges the high voltage 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 current (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 transforms 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
converts electrical energy from the
high voltage battery into mechanical
energy which is then transferred as
rotational torque to the wheels in
order to drive the vehicle.
• Reduction gear : Delivers rotational
force of the motor to the tires at
appropriate speeds and torque.
• EV Battery (Lithium-ion) : On board
high voltage storage device with a
capacity up to 64 kWh

à OBC : On-Board Charger

à LDC : Low Voltage DC-DC Converter
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, we recommend that you
contact an authorized HYUNDAI
dealer.
High Voltage Battery
(lithium-ion polymer)
• 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.
• Electric range may vary depending
on the driving conditions, 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
vehicle electric range.
• The high voltage battery is used when
using the air-conditioner / heater. This
may reduce the vehicle range. 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 vehicle
range.

If you have a flat tire while driving
If a tire goes flat while you are driving: • Take your foot off the accelerator
pedal and let the vehicle slow down
while driving straight ahead. Do not
apply the brakes immediately or
attempt to pull off the road as this
may cause loss of vehicle control
resulting in an accident. When the
vehicle has slowed to such a speed
that it is safe to do so, brake carefully
and pull off the road. Drive off the
road as far as possible and park on
firm, level ground. If you are on a
divided highway, do not park in the
median area between the two traffic lanes.
• When the vehicle is stopped, press the
hazard warning flasher button, shift to
P (Park), apply the parking brake, and
place the START/STOP button in the OFF position.
• Have all passengers get out of the
vehicle. Be sure they all get out on the
side of the vehicle that is away from
traffic.
• When changing a flat tire, follow the
instructions provided later in this
chapter.
