As 48V battery electric vehicles (BEV) are being introduced to the market, many global carmakers are considering the transition from 12V to 48V within their automotive systems. As 48V was previously only used to improve efficiency in mild hybrid vehicles, there are challenges to implementing a 48V low-voltage architecture in BEV, hybrid electric vehicles (HEV) and plug-in hybrid electric vehicles (PHEV) generating 48V off a high voltage battery. This presentation will outline 48V architectures and potential design solutions for 48V in future electric vehicles (EVs).
