DUBLIN—Research and Markets has announced the addition of the "Automotive 48V Power Supply Systems - Implications, Opportunities and Prospects - 2nd Edition" report to their offering.

Why are 48V power supply systems coming?

Leading industry executives say 48V systems can reduce the percentage of CO2 emissions by double digits, capture energy typically lost while braking, and provide torque in the low rpm range for start-stop hybrids.

48V Power Supply Systems can allow downsized engines to deliver fuel efficiency without a loss of engine performance.

But 48V systems promise more than energy efficiency and driving experience - they will affect climate control systems, for example, and a range of other power-consuming applications around the future vehicle.

How fast will they come?

The deployment of 48V is following the classic diffusion model of the automotive industry - from top end premium models, to high volume mass market models, and finally to low-cost entry level models. Diffusion rates are constrained by the industry's model cycle, but tougher fuel economy standards in Europe and China may be accelerating the usual innovation cycle - spurring new ideas and faster introduction.

What will be affected

The higher voltage is being used for handling stop-start systems, compressors, electric power steering, regenerative brakes and other energy-efficient electrical systems. But although it is driven by energy-saving, it has implications, potentially, for all the electrical systems in a vehicle. Initially 12V and 48V systems will coexist, but in the long run, as volumes rise and more 48V systems are offered in the mass market, car makers will look at the possibility of eliminating the older system.

What this report offers

The report offers insight into the opportunities and challenges offered by the development of 48V Power Supply Systems for automotive OEMs, established suppliers and potential new entrants.

It looks at new systems and new applications that are enabled by higher voltage power systems - and the ripple effects on electrical and electronic architectures and feature configurations that could follow.
