Eaton unveils 48-volt plans to support emissions rules

Eaton has unveiled a series of 48-volt offerings to support the shift from traditional 12- and 24-volt vehicle systems, as OEMs look for new ways to meet emissions regulations.

Many of today’s systems are driven directly by the mechanical power generated by an engine, which runs 12-volt systems like air conditioning and pumps, Eaton notes.

The manufacturer has responded with 48-volt systems including motor generators and inverters, as well as 48-volt DC/DC converters that step down from the 48-volt architecture to power 12- and 24-volt systems.

It’s also developing power electronics for 48-volt electric catalyst heating, an electric engine cooling fan and air conditioning compressor, and energy storage solutions such as lead-acid batteries and supercapacitors.
