In recent years 48 volt technology has been identified as an answer to some of the challenges faced by the automotive industry, and we are beginning to see the fruition of development in this area. Emission targets are a key driver for 48 volt systems, and electric vehicles and full hybrid vehicles have already demonstrated significant improvements in fuel efficiency.

The EU has set fleet average targets for CO2 of 95g/km by 2020, while China has installed targets of 117g/km by the same year. The US market has compelled manufacturers to reach average fuel economy targets of 54.5mpg by 2025. As the previous flirtation with higher voltage systems in the early 1990’s showed however, the cost of implementation in mass volume manufacturing has to be balanced against the benefits. Thus the development of mild-hybrid vehicles has gained traction in terms of efficiency and cost.
