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 240V 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.
The engine can be turned on based on a number of factors such as heater usage and a frequent operation of the
accelerator pedal by a driver in Charge Depleting mode.

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. Use only as a back-
up charger.
Charging Time
AC Charger: Takes about 2 hours
15 minutes 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.

LOCK mode (button indicator off) :
The connector locks when the
charging connector is plugged into
the charging inlet. The connector is
locked until all doors are unlocked
by the driver. This mode can be used
to prevent charging cable theft.
- If the charging connector isunlocked when all doors are
unlocked, but the charging cable
is not disconnected within 15 sec-
onds, the connector will be auto-
matically locked again.
- If the charging connector is unlocked when all doors are
unlocked, but all doors are locked
again, immediately, the connector
will be automatically locked again.
AUTO mode (button indicator on) : The connector locks when charg-
ing starts. The connector unlocks
when charging is complete. This
mode can be used when charging
in a public charging station.
If the connector does not unlock
automatically after the charging is
completed in AUTO mode, the con-
nector will unlock when all the
doors are unlocked. ❈ ❈
