48-volt commercial vehicle solutions

Many commercial vehicles will shift from 12- and 24-volt electrical architectures to 48-volt to enable manufacturers to achieve future emissions regulations.  As a leader in power conversion and protection, Eaton can assist commercial vehicle manufacturers in transitioning to 48-volt systems with various solutions to produce and manage that power safely and efficiently.

Stringent emissions regulations drive change

Across the globe, emission standards are tightening for vehicle manufacturers. Collectively, these new regulations will reduce tailpipe NOx limits by up to 90 percent and CO2 by up to 30 percent, thus accelerating the need for global engine manufacturers to employ additional emissions reduction strategies.

Traditionally, vehicles have operated with a 12- or 24-volt system, but with fuel economy regulations tightening and new power consuming components being added to vehicles, the need for more power is driving the move towards 48-volt systems.

Developing tailored solutions

Eaton can assist commercial vehicle manufacturers in the transition to 48-volt systems with technologies that reduce mechanical and incorporate more electrical components. From improving diesel engine efficiency, to 48-volt systems, to full vehicle electrification, Eaton takes a consultative approach to tailor the 48-volt technologies to meet emissions regulation challenges and system requirements.

On and off-highway OEMs are faced with significant challenges as components move toward electrification

Trucks and construction/agricultural equipment that once had hundreds of electrical circuits now have thousands. Multiplexing offers a cost-effective solution for simplifying and improving these systems.

Why OEMs are considering 48-volt electrical architectures

More stringent emissions regulations and increased demands on the vehicle's electrical architecture are driving commercial vehicle manufacturers toward 48-volt architectures.
