PHEV (Plug-in Hybrid Electric Vehicle) system

The Kia Plug-in Hybrid Electric Vehicle (PHEV) shares the characteristics of both a
conventional hybrid electric vehicle 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 distance until the hybrid battery becomes low. The driv -
ing distance in EV mode depends on the driver's driving style and road conditions.
Aggressive driving maneuvers may at times temporarily enable the engine to oper -
ate.
The engine power could be limited during the emission reduction control period at
cold engine condition.
The hybrid battery can be fully charged by connecting a plug to an external electric
power source.
An engine can be turned on due to factors such as the heater and a frequent opera -
tion of the accelerator pedal by a driver in CD mode.
