While sales for both battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs) are accelerating rapidly, there are other significant changes too. Vehicle electrical subsystem power loads have grown over 20x in recent years – driving interest in 48V systems that efficiently handle exponentially increased power demand while supporting 12V legacy systems. OEMs must respond with power delivery networks (PDNs) that match fluctuating market conditions. Very high-power density and efficiency from minimally sized, lightweight, flexible, scalable, reusable systems is essential.
This eBook shows that the best way to meet these objectives is to adopt a modular approach using compact, efficient, lightweight modules with high power density. It includes case studies covering various aspects of 48V and 12V system design; it also has more in-depth articles, which equip designers to better understand not only the EV PDNs, but also the infrastructures, and market conditions in which the vehicles must operate.
