48V electrical systems have advantages over current 12V systems, providing 4 times the power and providing greater efficiency when powering fans, pumps, electric power steering racks, and compressors. Higher voltages are more efficient, but automotive regulations demand costly shielded cabling (galvanic isolation) above 60V, so 48V systems keep the cost down. 48V systems used in Mild hybrids, are the cost effective, yet emission reducing first step on the electrification ladder.
48V electric supercharger
With the aim of reducing CO2 emissions, turbocharger systems are evolving from exhaust gas driven to electric driven forms for use in Mild Hybrid Electric Vehicles (MHEV). The superchargers improve the response of the engines at low revolutions and
