MAIN CHARACTERISTICS OF THE MILD
HYBRID SYSTEM
The main features of the Mild Hybrid
system are:
"eBraking" mode
"eCoasting" mode
"eCreeping" function
"eLaunch" mode
"eQueueing" mode
"eBoosting" mode
"eParking" mode
NOTE All of the characteristics listed
above cannot be selected by the driver,
but are activated automatically by the
Mild Hybrid system based on the driving
conditions and the state of charge of the

auxiliary battery.

For a description of the various features

WARNING
1) Improper use, or inappropriate
interventions on the system components,
can cause serious electric damage and
cause serious accidents that can even result
in death if the provided instructions are not
observed. Always contact an Alfa Romeo
Dealership.
2) In case of an accident, the system
9650025 components could have suffered damage
that cannot be seen. Do not touch or
tamper with damaged components of the
battery system: be careful to avoid short
circuits. Contact an Alfa Romeo Dealership
immediately.
3) Do not make any type of change to the
components of the battery system: always
contact an Alfa Romeo Dealership.
4) Do not puncture, crush, shake or deform
the battery system.
5) The lithium ion auxiliary battery (48V)
is located at the bottom of the vehicle:
therefore avoid getting the battery system
wet with any type of liquid and do not park
the vehicle over sources of external heat.
AUXILIARY BATTERY
(Mild Hybrid version)
6) 1) 1) 2)
The car is equipped with a sealed 48V
auxiliary lithium-ion battery with the
function of energy storage for the car.
The main functions performed by the
auxiliary lithium-ion battery are to
store the electric energy developed
while braking and to supply it to the
system when the electric motor starts to
function.
The auxiliary lithium ion battery is
partially charged during driving by
recovering the kinetic energy of the car
when slowing down and braking.
The auxiliary lithium ion battery
recharges automatically to ensure that
the charge level is always around 50% of
the maximum level, in order to take full
advantage of the hybrid functionality
and, at the same time, always have a
certain capacity useful for the energy
recovery operation.
The battery does not require any type of
maintenance.
To ensure that the lithium ion battery is
maintained properly over time, the car
must not be exposed to temperatures
below -10°C and above +40°C for
extended periods of time, as some
car functions may change or become
deactivated as the battery capacity
