Understanding the Vehicle
most demanding moments in terms of
consumption and emissions.
Based on the information from
the on-board sensors, the hybrid
system ECU decides when it is more
2
convenient recover energy such as
when a vehicle precedes, a phase in
which the system slows down the car
with the BSG generating energy to be
stored in the 48 V battery or to power
the car's services.
In certain driving conditions, the
hybrid system ECU also regulates
energy flows taking into account the
charge level of the 48 V battery. This
management is optimal especially
when using some ADAS systems
because the energy recovery start
automatically even when a vehicle is
detected in front of the car, slowing
down the vehicle with the activation
of the BSG.
The eBooster is used to support the
main turbocharger and improve
vehicle acceleration and driveability.
Bi-directional DC/DC converter is used
to link 48 V and 12 V board net. In
forward mode works as converter to
supply the 12 V net; in pre-charge
mode works as converter to pre-charge
the 48 V net with limited current.
The connection cable between the 48
V battery and the BSG is sufficiently
16
protected and housed in a position
that cannot be accessed by the user.
General Safety Instructions on
the 48 V Battery System
Although this is no high-voltage
battery system (link voltages remain
below 60 V), misuse or inappropriate
interventions on the system
components using insufficiently
insulated tools can generate short-
circuits and cause injury due to the
flow of high currents and/or the
resulting high temperatures. To avoid
these problems, carefully follow the
recommendations below.
WARNING!
• Battery system components may be
damaged in an accident, although
the damage may not be visible.
If you touch or move damage
components of battery system, you
may be electrocuted.
•
Never perform modifications to
components of battery system.
• Only technicians with the necessary
experience and equipment are
allowed to work on the battery
system. In case of battery system
problems, do not intervene but
contact the Service Network.
• Do not open the battery housing, or
otherwise disassemble the battery
system.
• Do not puncture, impact, crush,
shock, or deform the battery system.
• Avoid touching the battery housing,
as its surface may be hot both during
and after usage.
•
Do not wet the battery system with
any type of liquid.
•
Do not expose the battery system to
external heat.
• Do not cover or close the air intake
grill on the left side of the rear
parcel shelf with a plug/stopper.
The battery system must be able to
breath at any time.
In Case of Damage to the 48 V Battery
The 48 V battery cell has a hermetically
sealed metal housing and do not
represent a danger to health if the
battery is used correctly.
If the battery system is used
improperly, damaged, overheated,
abused, or unusual environmental
conditions may cause the cell to leak
with release of flammable electrolyte
fumes. In these cases the car warns the
user through the hybrid system failure
warning light and a message that
