12 V battery, which is certainly charged,
and more power is needed.
When acting as an electric motor, the
mild hybrid system provides additional
power to the thermal engine at start-up,
when starting from a standstill or when
there is a demand for greater drive
torque, or in the 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 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
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.
Understanding the Vehicle
•
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 rear bottom side passenger
compartment with a plug/stopper. The
air must circulate in the battery system
at any time to prevent its heating.
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
