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.
