DC/DC Converter Control Unit, Basic Function - GF54.10-P-9891A
MODEL all (CAR)
with CODE B01 (48V technology)
Location in engine compartment
Location in vehicle interior
Location
The DC/DC converter control unit together with the 48 V on-board electrical system battery is located as a power pack in either the engine compartment or the vehicle interior depending on the vehicle model and equipment involved.
Task
The DC/DC converter control unit consists of an output unit and a logic section. The output unit connects the 12 V on-board electrical system to the 48 V on-board electrical system, and it enables energy to be transferred in both directions. The logic section is responsible for communication with other control units and for actuation of the output unit.
The DC/DC converter control unit is connected to the network architecture of the vehicle and networked with the front central control unit and the 48 V on-board electrical system battery.
The DC/DC converter control unit also processes the following information:
- Circuit status
- Engine running status
- Starter-alternator status
- Starter-alternator voltage actual value
- Starter-alternator current actual value
- Charging voltage specified value
- On-board electrical system battery voltage actual value
- Battery current switch status
- Vehicle speed
- Status of driver door (open or closed)
The DC/DC converter control unit processes these input factors and also sends the following information:
- Operating rate of DC/DC converter
- DC/DC converter current
- Temperature of DC/DC converter
- Charge level of 48 V on-board electrical system battery
- Temperature of 48 V on-board electrical system battery
- Current of 48 V on-board electrical system battery
- Voltage of 48 V on-board electrical system battery
