Alternator
Due to the high power capacity of 180 A, the alternator is cooled by the engine's cooling
system to enhance heat dissipation. The brushless Bosch alternator is installed in an alu-
minum housing which is mounted to the engine block. The exterior alternator walls are sur-
rounded with circulated engine coolant. The function and design of the alternator is the
same as in the M62, with only minor modifications. The BSD interface (bit-serial data inter-
face) for the ECM is new.

section
Regulation
The alternator communicates with the Engine Control Module (ECM) via the BSD (bit-seri-
al data interface). The alternator conveys data such as model and manufacturer. This is
necessary to allow the engine management system to adapt it’s calculations and specific
control to the type of alternator fitted.
