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 high-voltage HEV bat
-
tery.
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 vehi
-
cle is driven by the electric motor with
the HEV battery.
The HEV battery charge must be main
-
tained, 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.
