Are the main drivers for future power supply system development FE improvement / CO2 reduction and an increased feature content? Is the dual voltage 48V / 12V architecture a potential solution to address these drivers? Bastian Hartmann, Research Engineer - Advanced Power Supply and Energy Management from the Ford Motor Company in Germany prepared the following presentation on the topic area "Drivers, opportunities and challenges of the 48V system".

AGENDA

3. 3 06/11/2014 FORD – Drivers, opportunities and challenges of the 48V system
 Fuel economy (cycle and real world)
 Extended stop/start operation
 Recuperation + torque assist or power supply of loads
 Reduced electrical losses
 New demand-controlled electrified actuators
 Electrification of mechanical PT actuators
 Increased feature content
 Comfort
 Driveability
 Increased electric demand, limits of 12V alternator capacity and ampacity of cables
-> voltage quality issues
 Weight reduction
 Downsized actuators and cables
