Electric Vehicles (EVs)
Battery electric vehicles (BEVs or
EVs) are driven using a battery and
an electric motor. While general vehi-
cles use an internal combustion
engine and gasoline as fuel, electric
vehicles use electrical energy that is
charged inside the high voltage bat-
tery. 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 ener-gy that is charged inside the high
voltage battery. In terms of air pol-
lution and greenhouse gas emis-
sions, EVs are cleaner than con-
ventional vehicles.
2. A 150 kW electric drive motor mated to a reduction gearbox
comprises the vehicle drivetrain.
This electric-only powertrain sig-
nificantly 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?
Regenerative braking uses the electric
motor when decelerating or braking
which converts vehicle motion (kinetic
energy) to electrical energy to charge
the high voltage battery.
Battery Information
The vehicle is composed of a highvoltage 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.

Lamp statusDetails
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 man-
agement is set to control the climate setting
and the heater or air conditioner is turned on.
Lamp statusDetails
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 POWER button is in the
OFF position with all doors, hood
and liftgate closed, the Aux. Battery
Saver+ activates according to the
auxiliary battery status.
Automatic Mode :
When the POWER button is in the
ON position with the charging con-
nector plugged in, the function acti-
vates according to the auxiliary bat-
tery status to prevent overdischarge
of the auxiliary battery.Information
• The Aux. Battery Saver+ activatesfor a maximum of 20 minutes. If the
Aux Battery Saver+ function acti-
vates for more than 10 times consec-
utively in automatic mode, the func-
tion will be disabled. (Note: There
may be a problem with the 12V aux-
iliary battery.)
If the vehicle is driven normally and
12V battery is able to charge nor-
mally, 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, a message will be dis-
played on the instrument cluster
and the high voltage battery level
may have decreased.

System Setting
The driver can activate the Aux.
Battery Saver+ function by placing
the POWER button to the ON posi-
tion and by selecting:
'User Settings →Other → Aux.
Battery Saver+'
The Aux. Battery Saver+ function
deactivates, when the driver cancels
the system setting.
LCD Message
This message is displayed when the
Aux. Battery Saver+ function has
been operating while the vehicle was
turned off.
However, if the LCD display mes-
sage pops up frequently, we recom-
mend that your vehicle's auxiliary
battery or electric/electronic compo-
nents be serviced by an authorized
HYUNDAI dealer.

When the function is activating
the indicator lamp will illumi-
nate and high voltage electricity
will be flowing in the vehicle. Do
not touch the high voltage elec-
tric 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.
