48V - a key automotive technology of the 2020s

48V is clearly going to be a very important technology in the coming decade. Some senior OEM executives say it should be one of those fundamental technologies that should be adopted by all ICE vehicles in the future. Key benefits for 48V are that it is is a system that augments combustion engines to reduce fuel consumption, reduces particulate emissions in diesels and improves the driver experience by increasing the responsiveness of the vehicle. 48V systems can help OEMs deliver most of the reductions in CO2 emisisons required by regulations at a fraction of the cost of full electrification - a real benefit in a world of political uncertainty about the future of EV subsidies - and without having to tackle the barriers to adoption (such as range and cost) thrown up by more fully electric solutions.

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.

Who buys Autelligence reports?

Currently over 250 companies have corporate or individual subscriptions to reports from Autelligence. Most reports are bought by CEOs, other C-level executives, partners, directors, vice-presidents and country managers at automotive suppliers across marketing, engineering, R&D, and purchasing functions. Subscribers also include OEMs, financial analysts and management consultants.

48V systems will get better

There is a lot of room for improvement in the technology, according to two leading engineering consultants familiar with the area:

Jason McConnell, Business Unit Director at IAV Automotive Engineering:

"People are looking to integrate technologies, putting the battery, power electronics from the inverter and the DC-DC converter in one box so you've got less cabling. 48V technologies can be adopted over a large number of vehicles; there's definitely reusability and scalability in most designs."

Tomasz Salamon, Engineering Operations Manager for Hybrid and Electric Systems at Ricardo: "Eventually we'll see more components going to 48V, which gives you smaller and more-efficient electrical components-and more power capability." And these benefits will be enhanced by scale effects.

Rudolf Stark, head of the Hybrid Electric Vehicle Business Unit at Continental has said that his company expects "good market penetration across all vehicle segments, from A to D." That, he says, will "bring large quantities of the technology to market" and "ensure cost-effective production".

Bonus 48V launch database

48-Volt power supply system database (June 2018) includes almost 600 announcements involving 48 -Volt Power supply systems, from May 2016 to June 2018. The majority of the announcements are new vehicle launches by OEMs. The spreadsheet also includes major announcements by suppliers such as Continental, Bosch, and Delphi, as well as other companies such as engineering consultancies.

OEM groups and brands are identified for each of the announcements and where a new model is involved the model and variant is identified. The list is searchable by country. For each announcement the list provides the headline summary and a link to the relevant news story.

Who is the report for?

Chief Executive Officers, Marketing Directors, Business and Sales Development executives, Product and Project management, Purchasing and Technical Directors that need a powerful third party perspective and overview of the trends and issues in their sector and the potential ramifications for their business.
