(Cost)-Efficient System Solutions e.g. Integrated Battery Management, Communication and Module Supply for the 48V Power Supply in Passenger Cars

摘要

Although the implementation of the 48V voltage supply in next generation passenger vehicles is certain to go ahead, economic and technical challenges remain to be overcome. The cost of lithium based batteries is falling, but costs for energy and power per liter/kg still remain an impediment to the application of the new voltage domain in high volumes. Engine cold-start, aging, efficient use of available energy and effective battery management systems are all facing problems that require technical solutions. ams AG provides (cost)-efficient IC solutions for lithium based battery systems, in-vehicle communication and power supplies for electronic modules for 48V systems. The Virtual Vehicle Competence Center provides the co-simulation environment for system integration and simulation-based evaluation of these systems.
