The 600 Hybrid version is powered by
an hybrid system that uses:
an electric motor ("e-machine")
integrated in the automatic
transmission, mechanically connected
to the heat engine and powered by an
auxiliary lithium ion battery (48V)
a BS (Belt Starter), activated by the
auxiliary services belt, which makes it
possible to start the heat engine with
the car stationary or when driving at a
low speed. In some phases, such as
during "electric driving", it replaces the
starter motor of the heat engine. In the
latter case, when the car is stopped
with automatic engine shutdown, the
engine will be restarted by the BS (Belt
Starter) device.
an auxiliary 48V lithium ion
battery that has the function of storing
energy for the car.
The Hybrid system makes it possible
to improve performance (prompter
response during transient stages), while
reducing fuel consumption and CO2
emissions.
NOTE The Hybrid system does not
operate continuously, but is activated
based on the state of the car, the state
of charge of the auxiliary lithium ion
battery (48V), the driving conditions
(acceleration/deceleration/braking,
engine starting) and on the conditions
of the road surface (e.g. downhill
road).The 48 V Li-ion (Lithium-
ion) auxiliary battery stores the
electrical energy needed to propel
the vehicle.The traction battery is
automatically charged to ensure that
the charge level is always around
50% of the maximum level, in order
to fully exploit the hybrid functionality
and, at the same time, always have
some capacity available for the energy
recovery operation.It is located under
the front left seat.The traction battery's
range varies depending on the type of
driving, the route and the ageing of its
components.
The Hybrid system provides a power
boost to the internal combustion
engine during vehicle start-up when
more traction torque is required, or at
times of higher fuel consumption and
emissions. In certain driving conditions,
the Hybrid system control module
regulates the energy flows based on
the charge level of the auxiliary lithium
ion battery (48V).
NOTE The vehicle always starts
with the petrol engine to ensure the
efficiency of the catalytic converter and
the availability of the brake assist.
The driving in all-electric is possible
for parking manoeuvring, for 20 mph
(30 km/h) speed zones in city, on
urban and country roads with smooth
driving and on motorways in slight
deceleration or downhill. The electric
motor is integrated into the automatic
gearbox.
With the PRND command in P ("Park")
and N ("Neutral"), an increase in noise
from the engine compartment may
be heard as the auxiliary battery (48V)
charging phase begins: this is normal
and not a fault.
Energy recovery
Maximise the vehicle's inertia by
releasing the accelerator pedal so that
the vehicle slows down by itself (e.g.
when driving downhill or approaching a
traffic light).
When the accelerator pedal is released,
provided that the slider on the power
indicator in the instrument panel is still
moving in the CHARGE zone, energy
recovery is optimal.
Energy recovery makes it possible to
make efficient use of the "passive"
