HYBRID SYSTEM
28
The electronic power supervisor 4
automatically manages the operation of the
two power units (Diesel and electric) to provide the lowest consumption.
An inverter and a transformer are needed to manage the electric power.
The inverter acts on the torque of the electric motor, by regulating the current
coming from the high voltage battery pack. Its operating range is between 150 and
270 volts.
The transformer converts the 200 V of the battery pack to 12 V, to power the
vehicle's ancillary systems.
The Stop & Start system 5
allows the Diesel engine to be put into standby dur-
ing stops (traffi c lights, a stop, or in a traffi c jam, for example) or during phases of
running in all-electric mode.
The stopping and restarting of the Diesel engine is done in a way that is instanta-
neous and transparent for the driver.
The electronic gear control gearbox 6
provides, in automatic mode, signifi cant
savings in fuel consumption compared to a conventional manual gearbox, thanks
to its electronic control system.
It also offers improved driving pleasure with the possibility at any time of choosing
the gear changing mode: automatic or manual, using the paddles located behind
the steering wheel.
