2018 KIA NIRO PLUG-IN HYBRID battery

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 360V 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 for the times when the engine acts as a generator, such as when
stopped at idle. Charging also occurs when decelerating or by regenerative braking.

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.
The engine can be turned on due to factors such as heater usage and a frequent operation of the accelerator pedal
by a driver in CD mode.

Charging Information
• Normal Charger: The plug-inhybrid vehicle is charged by plug-
ging into a normal charger installed
in your home or a public charging
station. (For further details, refer to
the 'Normal 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. Use only as a back-
up charger.
Charging Time
Normal Charger: Takes about 2hours 15 minutes at room tempera-
ture (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 : Use in emergency situations only.

When scheduled charging is setand the normal charger or the
portable charging cable (ICCB: In-
Cable Control Box) is connected
for 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 normal charger or
portable charging cable (ICCB: In-
Cable Control Box) is connected.
If charging is required immediately, turn off the scheduled charge
using the vehicle’s touchscreen or
UVO eco smartphone application
or press the vehicle's scheduled
charge release button( ).
When the scheduled charge is set, the charge start time is calculated
by itself. In some cases, charging
may start immediately after con-
necting the charger. If you press the scheduled charging
deactivation ( ) button to immedi-
ately charge the battery, charging
must be initiated 3 minutes after the
charging cable has been connected.
When you press the scheduled
charging deactivation ( ) button
for immediate charging, the sched-
uled charge setting is not com-
pletely deactivated. If you need to
completely deactivate the sched-
uled charge setting, use the AVN
to finalize the deactivation.
Refer to "Normal Charge or Trickle
Charge" for details about connect-
ing the normal charger and the
portable charger (ICCB: In-Cable
Control Box).

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 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.
Always inspect the charging con- nector terminals for damage or
overheating. Do not use if dam-
aged, as this may damage the
vehicle side charge connector and
is not a warrantable repair.
WARNING - Charging
cable
• Immediately stop charging when you find 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 and charging plug.
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 engine compartment
or interior rear seat may auto-
matically operate.

6. Check if the charging cable con-nection indicator of the high volt-
age battery in the instrument clus-
ter is turned ON.
Charging does not occur when the
indicator is OFF. When the charg-
ing connector is not connected
properly, reconnect the charging
cable to charge.
✽ ✽ NOTICE
• Charging is in progress only when
the shift lever is in P (Park).
Charging the battery with the
Engine Start/Stop button in the
ACC position is possible. However,
it may discharge the 12-V battery.
Thus, if possible, charge the bat-
tery with the Engine Start/Stop
button in the OFF position.
• The charging process is interrupt- ed temporarily when the shift lever
is moved from P (Park) to Not P(R
(Reverse)/N (Neutral)/D (Drive))
during charging. To resume(restart)
charging, move the shift lever to the
P (park) position. Then, the charging
process is resumed(restarted).
7. After charging has started, the
estimated charging time is dis-
played on the instrument cluster
for about 1 minute. It is also dis-
played, when the driver’s door is
opened with charging in progress.
When scheduled charging is set,
the estimated charging time is dis-
played as “--" .
