Hi voltage battery KIA OPTIMA PHEV 2020 Owners Manual

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.

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).

Changing plug-in hybrid mode
Pressing the HEV button changes
the plug-in hybrid system modes,
between Electric (Charge
Depleting/CD) mode and Hybrid
(Charge Sustaining/CS) mode.
Each time the mode is changed a
corresponding message is displayed
on the instrument cluster as follows.
Plug-in hybrid mode indicator
: The high-voltage(hybrid) battery is
used to drive the
vehicle.
: The high-voltage(hybrid) battery
and gasoline
engine is used to
drive the vehicle.
A corresponding message is displayed
to indicate the selected mode.

✽ ✽NOTICE
Coasting guide is only a supplemen-
tal system to assist with fuel-efficient
driving in certain situations. Thus,
the operating conditions may be dif-
ferent in accordance with
traffic/road conditions (i.e. driving
in a traffic jam, driving on a slope,
driving on a curve). Thus, take the
actual driving conditions into con-
sideration, such as distances from
the vehicles ahead/ behind, while
referring to the coasting guide sys-
tem as guidance.
Unplug vehicle to start
(Plug-in hybrid)
This message is displayed when you
start the engine without unplugging
the charging cable. Unplug the
charging cable, and then start the
vehicle.
Remaining time (Plug-in hybrid)
This message is displayed to notify
the remaining time to fully charge the
battery.

This message is displayed when the
charging connector is plugged with
the shift lever in R (Reverse), N
(Neutral) or D (Drive). Move the shift
lever to P (Park) and re-start the
charging process.
Electric/Hybrid modes (Plug-in hybrid)
A corresponding message is dis-
played when a mode is selected by
pressing the HEV button.
Low battery. Maintaining Hybridmode (Plug-in hybrid)
This message is displayed when the
vehicle is unable to convert to EV
mode even when pressing the HEV
button during HEV mode driving due
to insufficient high-voltage (hybrid)
battery level.

AUX. BATTERY SAVER+ (For
Plug-in Hybrid, if equipped)
The Aux. Battery Saver+ is a function
that monitors the charging status of
the 12V auxiliary battery.
If the auxiliary battery level is low, the
main high voltage battery charges
the auxiliary battery.
✽ ✽NOTICE
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 LCD display. For more infor-
mation, refer to the "System setting"
on the following page.
Mode

When the vehicle is OFF with all
doors, hood and liftgate closed, the
Aux. Battery Saver+ periodically acti-
vates according to the auxiliary bat-
tery status.

When the engine start/stop button is
in the ON position with the charging
connector plugged in, this function
activates according to the auxiliary
battery status to prevent over-dis-
charge of the auxiliary battery.
✽ ✽NOTICE
The Aux. Battery Saver+ activates
for a maximum of 20 minutes. If the
Aux. Battery Saver+ function acti-
vates more than 10 times consecu-
tively, in the Automatic Mode, this
function will stop activating, judg-
ing that there is a problem with the
auxiliary battery. In this case, drive
the vehicle for some period of time.
The function will start activating if
the auxiliary battery returns to nor-
mal.
✽ ✽NOTICE
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.

CAUTION
The Aux. Battery Saver+ func-
tion cannot prevent battery dis-charge if the auxiliary battery isdamaged, worn out, used as apower supply or unauthorizedelectronic devices are used.

System setting
The driver can activate the Aux.
Battery Saver+ function by placing
the engine start/stop button to the

"User Settings \bOther \b Aux.
Battery Saver+"
LCD message
This message is displayed when the
Aux. Battery Saver+ function has
been completed when the vehicle is
turned ON.
However, if the LCD message pops
up frequently, have your vehicle`s
auxiliary battery or electric/electronic
components serviced by an author-
ized Kia dealer.
OJFHP048632L
WARNING
The Aux. Battery Saver+ relies
on the high voltage battery to
charge the 12V battery. The
charging indicator lamp will blink
rapidly when this is occurring.
To reduce the risk of electrical
shock, do not touch any high
voltage components (orange) or
other electrical devices while
charging is occurring.
