Alternator: Description and Operation

Generator

The generator is liquid-cooled and has a rated current/output of 190 A/2,660 W or 220 A/3,080 W.

For the purposes of generator regulation, the battery sensor information is transferred to the gateway via a LIN (Local Interconnect Network) and the energy requirements are then calculated in the gateway (using an algorithm). The gateway sends this requirements request to the generator regulator, which is designed as a bit-synchronous interface regulator, and the generator regulator then regulates the energy requirements according to the requirements request. The gateway receives the utilization status via the DFM signal (Dynamo Field Monitor) and uses these values to recalculate the energy requirements in the vehicle electrical system.
