HEV (Hybrid Electric Vehicle) system
The Kia Hybrid Electric Vehicle (HEV) uses both the petrol engine and the electric
motor for power. The electric motor is run by a 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 vehicle is driven by the electric motor with the
HEV battery.
The HEV battery charge must be maintained, so at times the engine will come on
even at idle to act as a generator. Charging also occurs when decelerating or by
regenerative braking.
