The change to a 42-volt power system has been on the agenda since the late 1990s. Key to the development of the system was the realisation that existing 12-volt/14.2-volt (2W) vehicle power systems would no longer be adequate to deal with the requirements of forthcoming drive-by-wire technologies (including any moves towards automatic vehicle guidance systems, the so-called Intelligent Highway), telematics terminals and on-board multimedia packages.

The systems are likely to follow established industry patterns, being deployed initially in high-series cars and gradually cascading down to smaller vehicles. Early adopters are expected to include Cadillac, Jaguar, Mercedes-Benz and Volvo—all of whom have a vested interest in promoting radical chassis engineering/mechatronic developments.

New innovations mean new opportunities for your business as well as potential hurdles to overcome. Having reliable intelligence is, therefore, essential.

This report from ABOUT Automotive gives you the latest on 42-volt systems, assessing the current state of the market and predicting likely developments. The report also contains profiles of the major players.

Introduction

Chapter 1: Benefits

The changeover from 12-volt to 36-volt batteries – more to it than meets the eye?
Straight to 42 volt – or a hybrid? – manufacturers begin to decide on deployment options
The first 42-volt cars – still at the show stage, but with production models around the corner
Automatic stop and start processes – a key element in improved fuel efficiency
Engine developments – using 42 volts as a means of improving vehicle efficiency
Brake-by-wire and active suspension – how 42 volts can open potential for applications
Battery design – looking to the portable devices industry for inspiration
The truck industry – 42 volts offers the opportunity to catch up with car technology
Hybrid vehicles – how 42 volts can open up new design opportunities
Electronic components – a major market begins to respond to new challenges from 42 volt
Retro-fit accessories – how ready is the industry to deal with new voltage requirements?

Chapter 2: Ramifications

Electro-magnetic compliance – what impact will higher voltages have on interference levels?
Parts sourcing – an imperative to ensure component suppliers are able to meet new demands
Independent service garages – facing their own spares supply chain issues
Technician training – the need to cater for skills shortage cannot be overstressed
