High-voltage system
This BMW i is a hybrid vehicle. In addition to
the combustion engine, the vehicle features a
high-voltage system that consists of an elec‐
tric motor and a high-voltage battery among
other things.

units: the drive module made from aluminum
and the life module made from carbon fiber re‐
inforced plastic (carbon).At a glance1Vehicle battery2Electrical drive unit3High-voltage battery4Fuel filler flap5Combustion engine6Charging port
The concept
The hybrid system makes it possible to opti‐
mize fuel consumption and driving characteris‐
tics.
An electric motor assists the combustion en‐
gine. In certain driving situations, the vehicle
can also be driven using only electric power,
thereby reducing fuel consumption.
In addition to this, the electric motor acts like
an alternator: during braking and coasting, it
converts the vehicle's kinetic energy into elec‐ tricity. The current is stored in the high-voltage
battery and is used to drive the electric motor.
Functions
Acceleration boost: ASSIST and eBOOST
Driving off and accelerating require a lot of en‐
ergy. To reduce fuel consumption during high
acceleration and to optimize acceleration, the
electric motor supports the combustion en‐
