Hybrid/Plug-in Hybrid System Overview

H2
HEV (HYBRID ELECTRIC VEHICLE) SYSTEM
The Kia Hybrid Electric Vehicle (HEV) uses both the gasoline engine and the electric motor for power. The electric
motor is run by a 270V high-voltage HEV battery.
Depending on the driving conditions, the HEV computer selectively operates between the engine and the electric
motor or even both at the same time.
Fuel efficiency increases when the engine is at idle, or when the vehicle is driven by the electric motor with the HEV
battery.
The HEV battery charge must be maintained because, at times, the engine may come on even at idle to act as a gen-
erator. Charging also occurs when decelerating or by regenerative braking.

H3
PHEV (PLUG-IN ELECTRIC VEHICLE) SYSTEM
The Kia Plug-in Hybrid Electric Vehicle (PHEV) shares the characteristics of both a conventional hybrid electric vehi-
cle and an all-electric vehicle.
When used as a conventional hybrid electric vehicle, the HEV computer selectively operates between the engine and
the electric motor or even both at the same time.
When it is operating in the electric vehicle mode, the vehicle is driven only using the electric motor over a certain dis-
tance until the hybrid battery becomes low. The driving distance in EV mode depends on customer driving style and road
conditions. Aggressive driving maneuvers may at times temporarily enable the engine to operate for maximum power.
The hybrid battery can be fully charged by connecting a plug to an external electric power source.

Charging Information
• AC Charger: The plug-in hybridvehicle is charged by plugging into
a AC charger installed in your
home or a public charging station.
(For further details, refer to the 'AC
Charge'.)
Trickle Charger: The plug-in hybrid vehicle can be charged by using
household electricity. The electrical outlet in your home
must comply with regulations and
can safely accommodate the
Voltage / Current (Amps) / Power
(Watts) ratings specified on the
trickle charge.
Charging Time
AC Charger: Takes about from 2
and a half hours to 3 hours at room
temperature (Can be charged to
100%.). Depending on the condition and
durability of the high-voltage bat-
tery, charger specifications, and
ambient temperature, the time
required for charging the high-volt-
age battery may vary.
Trickle Charger: For charging at home. Please note that the Trickle
Charger is slower than the AC
Charger.

Charging Status
You can monitor the charging status
outside of the vehicle when charging
the high-voltage battery.
Scheduled Charging
(if equipped)
You can set reserved chargingusing the AVN.
Refer to the AVN for detailed infor-
mation about setting reserved
charging.
Scheduled charging can only be done when using a AC charger or
the portable charging cable (ICCB:
In-Cable Control Box).

H6 When scheduled charging is set
and the AC charger or the portable
charging cable (ICCB: In-Cable

charging, the indicator lamp blinks
(for 3 minutes) to indicate that
scheduled charging is set.
When scheduled charging is set, charging is not initiated immediate-
ly when the AC charger or portable
charging cable (ICCB: In-Cable
Control Box) is connected. When
immediate charging is required,
use the AVN to deactivate the
scheduled charge setting.

WARNING
- Fires caused by dust or
water
Do not connect the charging
cable connector plug to the
vehicle if there is water or dust
on the charging inlet.
Connecting while there is water
or dust on the charging cable
connector and plug may cause
a fire or electric shock.

WARNING
-
Public Electric Outlets
Do not use old or worn out pub-
lic electric outlets to charge
your vehicle. There may be a
risk of fire and injury when
using old worn out public elec-
trical outlets.

H7
Comply with the following in orderto prevent electrical shock when
charging:
- Use a waterproof charger
- Make sure to not touch the charg-ing connector and charging plug
when your hand is wet
- Do not charge when there is light- ning
- Do not charge when the charging connector and plug is wet
WARNING
-
Interference with electron-
ic medical devices
When using medical electric
devices such as an implantable
cardiac pacemaker, make sure to
ask the medical team and manu-
facturer whether charging your
electric vehicle will impact the
operation of the medical
devices. In some instances, elec-
tromagnetic waves that are gen-
erated from the charger can seri-
ously impact medical electric
devices such as an implantable
cardiac pacemaker.
WARNING
-
Touching the charging
connector
Do not touch the charging con-
nector, charging plug, and the
charging inlet when connecting
the charging connector cable to
the charging outlet and the
charging inlet on the vehicle.
Doing so may result in electro-
cution.

H8 Always keep the charging connec-
tor and charging plug in clean and
dry condition. Be sure to keep the
charging cable in a condition where
there is no water or moisture.
Make sure to use the designated charger for charging the vehicle.
Using any other charger may
cause failure.
Before charging the battery, turn the vehicle OFF.
Be careful not to drop the charging connector. The charging connector
can be damaged.
AC Charge
You can charge your vehicle by plug-
ging into a public charger at a charg-
ing station.

WARNING - Charging
cable
• Immediately stop charging when you discover abnormal
symptoms (smell, smoke).
Replace the charging cable if the cable coating is damaged
to prevent electrical shock.
When connecting or removing the charging cable, make sure
to hold the charging connec-
tor handle.
If you pull the cable itself
(without using the handle), the
internal wires may disconnect
or get damaged. This may lead
to electric shock or fire.
WARNING - Cooling fan
Do not touch the cooling fan
while vehicle is charging. When
the vehicle is switched OFF
while charging, the cooling fan
inside the motor compartment
may automatically operate.
