Infineon's extensive portfolio for 48 V systems in EVs & mild hybrids
In the pursuit of zero CO? emissions, efficient hybridization and electrification of mobility is crucial. Infineon stands for the introduction of the 48 V power supply and already offers an extensive application and product portfolio for 48 V solutions in electric and mild hybrid cars. Traditionally, battery electric vehicles (BEVs) have been equipped with a high-voltage (HV) power supply and a 12 V power supply. With the increasing number of new BEV platforms, the stage is set for incorporating a 48 V rail as a third voltage rail in the power distribution system (PDS).
48 V as replacement for 12 V power supply
This solution has the potential for overall savings across the vehicle ecosystem ¡ª for passenger cars as well as commercial and agricultural vehicles. As the market leader in automotive semiconductor solutions, we work with our customers to develop a holistic approach across the entire vehicle usage pattern and parameter range. Discover Infineon's comprehensive 48 V system portfolio for many applications in electric vehicles.
48 V as third voltage rail in electric cars
Lower cost, reduced harness weight and simplified mounting or heat sink design are one of the main goals for 48 V add-on applications in electric vehicles. With our comprehensive chipset solutions, our customers can realize a cost potential of up to 30% at vehicle system level based on current Si /SiC and future GaN-technologies.
Efficient 48 V mild hybrid systems
48 V in mild hybrid electric vehicles (MHEV) will pave the way for meeting stricter regulations for CO? emissions (e.g. Euro7) and enabling higher efficiency for internal combustion engine (ICE) vehicles. With more than 7 years of experience in supplying 48 V applications for the automotive industry, we support our customers with outstanding system knowledge.
