Electric Vehicle (EVs)
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 (EVs)
1. EVs are using the electrical energy that is charged inside the high voltage
battery. In terms of air pollution and
greenhouse gas emissions, EVs are
cleaner than conventional vehicles.
2. A 150 kW electric drive motor mated to a reduction gearbox comprises
the vehicle drivetrain. This electric-
only powertrain significantly reduces
engine room noise and vibration while driving.
3. When decelerating or driving downhill, regenerative braking is
utilized to charge the high voltage
battery. This helps to minimize energy
loss and increases vehicle range.
4. When the state of charge (SOC) of the
battery is low, the EV battery can be
recharged through several different
charging methods. Refer to “Charging
Information” later in this section.
Information
What does regenerative braking do?
It uses an electric motor when decelerating and braking and transforms kinetic
energy to electrical energy in order to
charge the high voltage battery. (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 system.
• The auxiliary battery is automatically
charged when the vehicle is in the
ready (
) mode or the high voltage
battery is being charged.

Driving history
OOSEV040538L
The driving history displays information
from the last several driving cycles
including date, distance traveled and
energy efficiency rate. A star icon
indicates the driving cycle with the most
efficient energy consumption rate.
EV Settings
OOSEV040539L
Select ‘EV ÞECO settings’ on the
screen. You can set the Winter mode,
Warning and EV route functions.
Utility Mode
The high voltage battery is used instead
of the 12V auxiliary battery for operating
the convenient features of the vehicle.
When driving is not necessary such as
while camping or when stopping the
vehicle for a long time, it is possible to
use the electrical devices (audio, lights,
air conditioner, heater, etc.) for long
hours.

Lamp status Details
An LED in the front of the vehicle near the inner portion of the
H-emblem indicates when the EV battery is being used while the
vehicle is stationary.
The EV battery may be in use to charge the 12V auxiliary battery or
when charge management is set to control the climate setting and the
heater or air conditioner is turned on.
(4) Immediate charging
Lamp status Details
To override any charge scheduling that has previously been set, you
can press the scheduled charging deactivation button.
Scheduled charging will be deactivated allowing you to charge
immediately.

Aux. Battery Saver+
The Aux. Battery Saver+ is a function that
monitors the charging status of the 12 V
auxiliary battery.
If the auxiliary battery level is low, the
main high voltage battery charges the
auxiliary battery.
Information
The Aux. Battery Saver+ function will
be ON when the vehicle is delivered. If the function is not needed, you may turn it off in the Users Settings mode on the
cluster. For more information, refer to the following page.
Mode • Cycle Mode :
When the Start/Stop button is in
the OFF position with all doors,
hood and tailgate closed, the Aux.
Battery Saver+ periodically activates
according to the auxiliary battery
status.
• Automatic Mode :
When the Start/Stop button is in
the ON position with the charging
connector plugged in, the function
activates according to the auxiliary
battery status to prevent over
discharge of the auxiliary battery.
Information
• The Aux. Battery Saver+ activates
for a maximum of 20 minutes. If the Aux Battery Saver+ function activates
for more than 10 times consecutively in automatic mode, the function will
be disabled. (Note: There may be
a problem with the 12V auxiliary
battery.) If the vehicle is driven normally and
12V battery is able to charge normally,
the Aux. Battery Saver+ function will be enabled again.
• The Aux. Battery Saver+ function
cannot prevent battery discharge if the auxiliary battery is damaged, worn out,
used as a power supply or unauthorized
electronic devices are used.
• If the Aux. Battery Saver+ function was activated, the high voltage battery level
may have decreased.
WARNING
OOSEV010011L
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.

If an accident occurs
WARNING
• When a vehicle accident occurs,
move the vehicle to a safe place,
turn OFF the vehicle and remove the
auxiliary battery (12 V) terminal to
prevent high voltage electricity from
flowing.
• If electric wires are exposed from
inside or outside the vehicle, do not
touch the wires.
Also, 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.
WARNING
• When a vehicle accident occurs and
the high voltage battery is damaged,
harmful gas and electrolytes may
leak. Be careful not to touch the
leaked liquid.
• When you suspect leakage of
inflammable gas and other harmful
gases, open the windows and
evacuate to a safe place. If any
leaked fluid comes in contact with
your eyes or skin, immediately clean
the affected area thoroughly with
tap water or saline solution and
have doctors inspect it as soon as possible.
WARNING
• If a small scale fire occurs, use a fire
extinguisher (ABC, BC) that is meant
for electrical fires. If it is impossible
to extinguish the fire in the early
stage, remain a safe distance from
the vehicle and immediately call the
fire department. Also, advise them
that an electric vehicle is involved.
• If the fire spreads to the high
voltage battery, large amount of
water is needed to put out the fire.
Using small amount of water or
fire extinguishers not meant for
electrical fires could cause serious
injury or death from electrical
shocks.
WARNING
If you cannot put out the fire
immediately, the high voltage battery
may explode. Evacuate to a safe place
and do not let other people approach
the site.
Contact the fire department and notify
them of an electric vehicle fire. • If the vehicle is flooded with water,
immediately turn off the vehicle and
evacuate to a safe place. Contact
the fire department or an authorized
HYUNDAI dealer.
