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.

01
1-9
•
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
distance to empty keep falling,
contact an authorized HYUNDAI
dealer 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 discharging.
Also, if the charge amount is not
enough, immediately charge to full
and store the vehicle.
• AC 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 performance
in optimal condition if you charge the
high voltage battery to 100%. (Once a
month or more is recommended.)
The value of the high voltage battery
charge level may vary according to
the charging conditions (state of
charger, outside temperature, battery
temperature, etc.). In order to fully
charge the battery, the current of the
high voltage battery will be gradually
decreased, so that the longevity and
safety of the battery can be secured.
CAUTION
• If the vehicle is kept with insufficient
charge 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 connected.
• Using the V2L function may reduce
the mileage due to the use of high
voltage battery energy, and repeated
use of the V2L function may cause
a decrease in the life of the high
voltage battery.
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 connected, the
warmer system automatically operates
according to the battery temperature.
Charging time may shorten compare to
vehicles without the high voltage battery
warmer system. But, electricity charge
may increase because of high voltage
battery warmer system operation.
CAUTION
The high voltage battery warmer
system operates when the charging
connector is connected to the vehicle.
However, the high voltage warmer
system may not operate when battery
temperature drops below -31°F (-35°C).

How to connect
Outdoor
ONE1Q011063
1. Open the cover of the V2L connector.
2. Close the cover after connecting home appliances and electronical
products to the power outlet.
3. Connect the V2L connector to the charging inlet on the vehicle.
4. Press the switch (1) of the V2L
connector and check whether the
light (2) is on or off. The light (2) may
not turn on normally when:
- See the battery discharging limit for high voltage battery for driving
in ‘Electricity Use’ menu on the
screen. If it is higher than the
current amounts of high voltage
battery, the light (2) does not turn on.
- Check whether the light of V2L connector or indoor power outlet
turns on or not. - If the warning message for V2L
appears on the cluster, refer to the
message entirely.
- If V2L does not operate previously when you connects another home
appliances, have your vehicle
inspected by an authorized
HYUNDAI dealer.
5. Press the switch (1) to turn off the light (2) the the V2L will be off. You can
disconnect the V2 connector when
the light (2) turns off or the charging
connecter lock is deactivated pressing
the door unlock button on the smart
key.
Information
Please connect the V2L connector to the
charging inlet within 60 seconds after the
charging cover opens. To prevent theft
after connecting, it is changed to auto lock automatically so that it is impossible to separate.
When using V2L, cancel the scheduled air
conditioning setting. V2L operation may
be blocked by scheduled air conditioning operation conditions.

Charging the eleCtriC vehiCle (abrupt stop)
Action to be taken when charging stops abruptly
When the high voltage battery does not charge, check the followings:
1. Check the charging setting for the vehicle. Refer to “Charge Management”, in this chapter (for example, When scheduled charging is set, charging is not initiated
immediately when the AC charger or portable charger (ICCB: In-Cable Control Box)
is connected.)
2. Check the operation status of AC charger, portable charger and DC charger. (Charging Status Indicator Lamp for Portable Charger, refer to “Checking Charging
Status” for trickle charge in this chapter.)
à Actual method for indicating the charging status may vary in accordance with the
charger manufacturer.
3. When the vehicle does not charge and a warning message appears on the cluster, check the corresponding message. Refer to “LCD Display Messages”, in this chapter.
4. If the vehicle is properly charged when charged with another normally working
charger, contact the charger manufacturer.
5. If the vehicle does not charge when charged with another normally working charger, contact an authorized HYUNDAI dealer for inspection.
6. If charging fails and the service warning light (
) is lit in the cluster, contact an
authorized HYUNDAI dealer.

WARNING
ONE1Q011038
When the function is activating the
indicator lamp will illuminate and high
voltage electricity will be flowing in the
vehicle. Do not touch the high voltage
electric wire (orange), connector, and
all electric components and devices.
This may cause electric shock and lead
to injuries. Also, do not modify your
vehicle in any way. This may affect your
vehicle performance and lead to an
accident.
